== 'Wikidata item' link is moving, finally. ==
Hello everyone, I previously wrote on the 27th September to advise that the ''Wikidata item'' sitelink will change places in the sidebar menu, moving from the '''General''' section into the '''In Other Projects''' section. The scheduled rollout date of 04.10.2024 was delayed due to a necessary request for Mobile/MinervaNeue skin. I am happy to inform that the global rollout can now proceed and will occur later today, 22.10.2024 at 15:00 UTC-2. [[m:Talk:Wikidata_For_Wikimedia_Projects/Projects/Move_Wikidata_item_link|Please let us know]] if you notice any problems or bugs after this change. There should be no need for null-edits or purging cache for the changes to occur. Kind regards, -[[m:User:Danny Benjafield (WMDE)|Danny Benjafield (WMDE)]] 11:28, 22 October 2024 (UTC)

:Hi @[[User:Danny Benjafield (WMDE)|Danny Benjafield (WMDE)]]: I Just noticed your post above, and it is timely.
:I have been participating in the English WikiUniversity for a few years, much less often recently. I seems like something in the way the site displays is different, but I cannot put my finger on it. Your posting gave me a clue. Can you please tell me where the link to wikidata items has moved to? [[User:Ottawahitech|Ottawahitech]] ([[User talk:Ottawahitech|discuss]] • [[Special:Contributions/Ottawahitech|contribs]]) 17:23, 11 December 2024 (UTC)
::Hello @[[User:Ottawahitech|Ottawahitech]], sure, I would be happy to. The button/sitelink name didn't change, just its position. You should find it in the sidebar-menu under the section '''In other projects''' (where the links to all other Wikimedia Projects are displayed). If you do not see it, please reach out to us on the [[m:Talk:Wikidata_For_Wikimedia_Projects/Projects/Move_Wikidata_item_link|Move Wikidata item - Discussion page]]. Thank you, -[[User:Danny Benjafield (WMDE)|Danny Benjafield (WMDE)]] ([[User talk:Danny Benjafield (WMDE)|discuss]] • [[Special:Contributions/Danny Benjafield (WMDE)|contribs]]) 09:24, 12 December 2024 (UTC)
:::@[[User:Danny Benjafield (WMDE)|Danny Benjafield (WMDE)]], thank you for responding. I intend to followup on the ''Move Wikidata item - Discussion page'' as per your post above by putting it on my ever growing todo list.
:::I don't know about others on this wiki, as I said I have not been visiting here frequently, but for me the constant changes are a big distraction. I have been around wikimedia projects since 2007, so why do I have to spend so much time learning and re-learning how to find what I came here for? [[User:Ottawahitech|Ottawahitech]] ([[User talk:Ottawahitech|discuss]] • [[Special:Contributions/Ottawahitech|contribs]]) 16:41, 12 December 2024 (UTC)
::::Hi @[[User:Ottawahitech|Ottawahitech]], thanks for you thoughts. Your input whether positive or critical helps us understand the impacts to editors so we welcome your further thoughts when you reach us in your To Do List :)
::::I can't speak about the other changes you've experienced here but I do hope they are made with a spirit of improvement for the community as a whole. -[[User:Danny Benjafield (WMDE)|Danny Benjafield (WMDE)]] ([[User talk:Danny Benjafield (WMDE)|discuss]] • [[Special:Contributions/Danny Benjafield (WMDE)|contribs]]) 10:43, 16 December 2024 (UTC)
:::::@[[User:Danny Benjafield (WMDE)|Danny Benjafield (WMDE)]]:
:::::Re: '''Your input whether positive or critical helps us understand the impacts to editors'''
:::::Today I (finally) checked [[Move Wikidata item - Discussion page]] and discovered that it is a talkpage on META where, unfortunately, I am infinitely blocked, so cannot participate. Even so, I proceeded to try and see what others are saying and immediately came to the conclusion that the few who actually participated in that discussin viewed the change negatively. It must be disheartening for developers to meet such a hostile attitude from the community. Please don't take it personally, this is a common phenomena in wikimedia community wide discussions , IMIO.
:::::I further checked the [https://pageviews.wmcloud.org/?project=meta.wikimedia.org&platform=all-access&agent=user&redirects=0&range=latest-90&pages=Talk:Wikidata_For_Wikimedia_Projects/Projects/Move_Wikidata_item_link page view statistcics] which showed there were only 828 pageviews in the last 90 days, and what's worse [https://meta.wikimedia.org/w/index.php?title=Talk:Wikidata_For_Wikimedia_Projects/Projects/Move_Wikidata_item_link&action=info#mw-pageinfo-watchers the page has "Fewer than 30 watchers"].
:::::Since [[META:User:Danny Benjafield (WMDE)|your userpage on META]] says that you are the: "Community Communications Manager Wikidata Integrations Team", may I ask how this apparent apathy is being addressed by your own management?
:::::I apologize if my post is not welcome on the Wikiversity:Colloquium, as i said I am a rather infrequent visitor to this wiki. I probably would not have followed up if you did not assure us that our feedback positive or negative is sought. Cheers, [[User:Ottawahitech|Ottawahitech]] ([[User talk:Ottawahitech|discuss]] • [[Special:Contributions/Ottawahitech|contribs]]) 20:49, 3 January 2025 (UTC)
::::::Dear @[[User:Ottawahitech|Ottawahitech]], I am so so sorry for leaving you on read for these last months, I have no excuse other than reading your comment and then getting lost before making a reply.
::::::The team I am working with, [[m:Wikidata_For_Wikimedia_Projects|Wikidata for Wikimedia Projects]] is a new development team, so I think management has allowed a certain amount of elbow room or leeway for us to make small changes whilst developing our confidence tackling the MediaWiki codebase with onboarding tasks that won't 'rock the boat' too much. We certainly expected some pushback or resistance to moving the Wikidata item as editors are so used to where it previously resided. Now it has been some time and hopefully the communities have gotten used to the change.
::::::Please do not apologise, your comments are always welcome, critical or not, as a new team I think we certainly "fly under the radar" to an extent and I hope that changes as we continue to work on projects that deepen the integrations between Wikidata and the other sibling projects. Once again, my sincere apologies for the delay in this reply. -[[User:Danny Benjafield (WMDE)|Danny Benjafield (WMDE)]] ([[User talk:Danny Benjafield (WMDE)|discuss]] • [[Special:Contributions/Danny Benjafield (WMDE)|contribs]]) 13:59, 1 April 2025 (UTC)
== Wikiversity - Newsletters ==
Hello All,
I wanted to create a newsletter on Wikiversity, which would highlight what is going on in certain months and events on Wikiversity; which would bolster engagement by many people. This would be on the website and would have its dedicated 'Newsletter' tab.
I hope you acknowledge this idea. [[User:RockTransport|RockTransport]] ([[User talk:RockTransport|discuss]] • [[Special:Contributions/RockTransport|contribs]]) 21:05, 8 December 2024 (UTC)
:@[[User:RockTransport|RockTransport]], What sort of things do you plan to include in your newsletter? Will they be different than what is currently in [[Main Page/News]]? Just curious.
:I am also wondering about your motive which I think is: to bolster engagement by many people. I am asking because I wonder if others who are currently active here also think this I is desirable? Have you asked them? [[User:Ottawahitech|Ottawahitech]] ([[User talk:Ottawahitech|discuss]] • [[Special:Contributions/Ottawahitech|contribs]]) 17:34, 11 December 2024 (UTC)
::Not yet, which was why I was asking this on the colloquium. I plan to include things that many people have created on Wikiversity over the month, as it is a monthly newsletter. It would be somewhere on the website here. It will be more frequent that the ones seen on [[Main Page/News]]. We will include people's resources to essentially promote them. [[User:RockTransport|RockTransport]] ([[User talk:RockTransport|discuss]] • [[Special:Contributions/RockTransport|contribs]]) 06:50, 12 December 2024 (UTC)
:::@[[User:RockTransport|RockTransport]], I Think what you are saying is that ''Main Page/News'' does not update frequently enough?
:::If this is the reason, why not start small by simply increasing the frequency of posting news on the main page, instead of trying to start a newsletter?
:::If there is more, can you articulate what else is missing. Thanks in advance, [[User:Ottawahitech|Ottawahitech]] ([[User talk:Ottawahitech|discuss]] • [[Special:Contributions/Ottawahitech|contribs]]) 16:51, 12 December 2024 (UTC)
::::I meant going to detail into topics covered in that month, rather than just giving a few points. [[User:RockTransport|RockTransport]] ([[User talk:RockTransport|discuss]] • [[Special:Contributions/RockTransport|contribs]]) 16:53, 12 December 2024 (UTC)
:::::What sort of details did you have in mind? You can pick one of the links provided in [[Main Page/News]] to illustrate. cheers, [[User:Ottawahitech|Ottawahitech]] ([[User talk:Ottawahitech|discuss]] • [[Special:Contributions/Ottawahitech|contribs]]) 15:29, 16 December 2024 (UTC)
::::::I'm thinking of the community entering their projects, and discussing those in the newsletter. It depends on what they want, though. There would be a dedicated page for giving the information about their projects [[User:RockTransport|RockTransport]] ([[User talk:RockTransport|discuss]] • [[Special:Contributions/RockTransport|contribs]]) 17:24, 16 December 2024 (UTC)
:::::::I might start working on this soon, depending on the projects being created on Wikiversity. @[[User:Ottawahitech|Ottawahitech]] @[[User:Atcovi|Atcovi]] [[User:RockTransport|RockTransport]] ([[User talk:RockTransport|discuss]] • [[Special:Contributions/RockTransport|contribs]]) 18:25, 17 December 2024 (UTC)
::::::::I'd recommend you start off with putting this under a userspace page (something like [[User:RockTransport/Wikiversity Newsletter]]), and drafting what you desire. Let us know once it's done, and the community can provide their input. —[[User:Atcovi|Atcovi]] [[User talk:Atcovi|(Talk]] - [[Special:Contributions/Atcovi|Contribs)]] 18:30, 17 December 2024 (UTC)
:::::::::I will try and make one for this month. This is supposed to be a monthly newsletter, showcasing the different projects mentioned there. Users can put their projects, and we will document them on the newsletter.

::::I '''might''' be able to icnrease the frequency there, but it doesn't go into detail about these topics. [[User:RockTransport|RockTransport]] ([[User talk:RockTransport|discuss]] • [[Special:Contributions/RockTransport|contribs]]) 17:30, 18 December 2024 (UTC)

== <s>Degrees</s> (Certificates (see below)) ==
Why does Wikiversity not provide degrees? I know it was a promise to the Wikimedia Foundation in the Wikiversity project proposal. But anyway, why is that? Wikiversity is about opening doors, i.e., removing obstacles. So, what kind of an obstacle was a paper? Was a certain body of knowledge that you learned well?! Because Wikiversity is not accredited for that? Yes, and do we need official US accreditation? We cannot create our system so that the learners who learn here and would like to continue their science career have a recognizable degree they can continue? [[User:Juandev|Juandev]] ([[User talk:Juandev|discuss]] • [[Special:Contributions/Juandev|contribs]]) 10:19, 18 December 2024 (UTC)
:"I know it was a promise to the Wikimedia Foundation in the Wikiversity project proposal." Was it? Becoming a degree-granting institution is an extremely high bar in the United States, but what is even the point in becoming a degree-granting institution in... Malawi? Tonga? Somewhere else where the servers aren't located or the WMF aren't incorporated? —[[User:Koavf|Justin (<span style="color:grey">ko'''a'''vf</span>)]]<span style="color:red">❤[[User talk:Koavf|T]]☮[[Special:Contributions/Koavf|C]]☺[[Special:Emailuser/Koavf|M]]☯</span> 15:53, 18 December 2024 (UTC)
::I ment certificates. The question is the recognazibility of a certificate. I am not talking here about equal certification, which is provided by governmental institucians to universities, rather on Wikiversity own certification, which might may advocate itself over the time. [[User:Juandev|Juandev]] ([[User talk:Juandev|discuss]] • [[Special:Contributions/Juandev|contribs]]) 15:05, 19 December 2024 (UTC)
::: We could issue certificates in some residing in certain jurisdictions probably (?). To my knowledge, there is no legal prohibition federally against doing this in the USA as long as no misrepresentation happens. Although some states might prohibit it (?). Degrees are likely different (at least with respect to accreditation). Please let me know if you believe I am likely incorrect in my understanding. I asked an LLM this prompt, "is there any prohibition legally in USA for a DAO (decentralized autonomous organization or wiki community related to learning, teaching, and research) from issuing certifications or certificates to those who go through learning materials and educational resources that might be on a decentralized or nonprofit wiki that has an active community?" (i won't post the specific result, but I wrote and engineered that prompt myself). The LLM output seemed to indicate my understanding noted here is correct, but LLM's are sometimes wrong. what do you or others think about this? [[User:Michael Ten|Michael Ten]] ([[User talk:Michael Ten|discuss]] • [[Special:Contributions/Michael Ten|contribs]]) 18:49, 25 December 2024 (UTC)
:From [https://web.archive.org/web/20170703053134/https://wikimediafoundation.org/wiki/Meetings/November_13,_2005 the WMF Board] (repeated at [[WV:WWIN]]):
:<blockquote>"[[Wikiversity:Original proposal|Wikiversity proposal]] not approved, but we will approve it if [[Wikiversity:Approved Wikiversity project proposal|some changes are made]]... The board recommend rewriting the proposal to ''exclude credentials'', exclude online-courses and clarify the concept of elearning platform."</blockquote>
:That is, Wikiversity was prevented from creation until it was codified '''not''' to provide credentials. It is not just ''U.S.'' credentials, but credentials period.
:I see you were around for [[Wikiversity:Community Review/Wikimedia Ethics:Ethical Breaching Experiments|the Reckoning]], so I imagine you are aware of the potential consequences of challenging such a clear policy so explicitly. I worry the community would not withstand another round. [[User:Tule-hog|Tule-hog]] ([[User talk:Tule-hog|discuss]] • [[Special:Contributions/Tule-hog|contribs]]) 19:24, 2 January 2025 (UTC)
::That said, I see nothing wrong with a cute badge of some sort (emulating barnstars) for completion of a resource (perhaps supervised/signed off by the resource creators). Even if there is no pretention of "credentials", who doesn't like a trophy?

:::[[:w:Gamification|Gamification]] is quite different than granting certificates and degrees. And ''even'' if Wikiversity grants certificates, half the battle is getting others to recognize the legitimacy of the certificate. Otherwise people will just think of Wikiversity as a [[:w:diploma mill|diploma mill]] especially if this conversation steers towards purposely issuing certificates in far flung countries for the sole purpose of skirting around the rules. And that's something I don't want to be associated with if Wikiversity goes down that path.

== Citation system ==
How is being maintained citation system on en.wv. I mean, is it completly the same as on English Wikipedia? Do we update it according to English Wikipedia? How we do that? Are the templates like [[Template:Cite book|Cite book]] based on Lua? I dont see any invoke word. [[User:Juandev|Juandev]] ([[User talk:Juandev|discuss]] • [[Special:Contributions/Juandev|contribs]]) 16:20, 2 January 2025 (UTC)
:I was just working on references in [[WikiJournal Preprints/Mobility-aware Scheduling in Fog Computing: Analysis and Challenges]]. And I agree with you. The citation system is so outdated compared to en.wp. Just the fact that I have to do extra clicks to access {{tl|cite journal}} is bizarre. Are there efforts to sync updates to the current citation version on en.wp?

::Not mine, I am just wondering if there is an easy system how to take over citation aparatus. I havent investigated the citation system on English Wikipedia yet, but on the first glance it looks like a very complicated environment. So in the following days Ill be looking on it if its a way to overtake it or if it would be easier to create own citation system.

== Proposal: citation templates for VisualEditor ==
@[[User:OhanaUnited|OhanaUnited]] [[Wikiversity:Colloquium#Citation system|pointed above]], that they had a hard time to create citations via VisualEditor I believe. I think its because of missing map in [[MediaWiki:Cite-tool-definition.json]] ([[phab:T219551|see also]]). And the question is, which citation templates the editor should list. So I would propose the same as on en.wp, i.e. [[Template:Cite book|Cite book]], [[Template:Cite journal|journal]], [[Template:Cite news|news]], and [[Template:Cite web|web]]. [[User:Juandev|Juandev]] ([[User talk:Juandev|discuss]] • [[Special:Contributions/Juandev|contribs]]) 13:38, 3 January 2025 (UTC)
:I support those four templates (book, journal, news, web). Another part of me wonders if we should include other use cases like AV media, thesis and report. But they may have limited usage and will only clutter the screen.

== Deletion of talk pages ==
I wonder if there are any policies here that define when talkpages are deleted?
Thanks in advance, [[User:Ottawahitech|Ottawahitech]] ([[User talk:Ottawahitech|discuss]] • [[Special:Contributions/Ottawahitech|contribs]]) 17:30, 17 January 2025 (UTC)
:I'm not too sure if there are any topics about this. [[User:RockTransport|''Rock Transport'']] 😊 ([[User_talk:RockTransport|Talk page]]) 19:37, 17 January 2025 (UTC)
::Let me explain why I am asking about deletion:
::I have recently posted a question on a WV talk-page. The page was empty when I arrived, so had to be created, or recreated as it turns out because when I tried to post I received this box that said the page had been deleted by @[[User:Guy vandegrift|Guy vandegrift]] as a test page. I then Went ahead and recreated the page by posting at:
::[[Wikiversity talk:Wikidebate/Guy vandegrift#Do we need dialogues?]].
::However a bit later I remembered a discussion on the English Wikiquote Village Pump which was started by a contributor who was active there a long time ago who apparently was looking for their own contributions. It turned out that the history of the contributions had disappeared when the page was deleted and then re-created by another contributor who's became, at least according to the View history, the "owner" of all the previous contributions. Here is the ENWQ-VP discussion: https://en.wikiquote.org/wiki/Wikiquote:Village_pump#Now_this_is_contrary_to_the_spirit_of_Wikipedia.
::I believe deletions of old pages that seem unimportant to new users of the English Wikversity may become problematic in the future. I know that at least one [[User:MathXplore|new admin]] has been added in the last couple of years, but I am not sure how many of the experienced admins are still active, so I don't know who makes deletion decisions here.. History is crucial to maintain when people are no longeraround.
::It would be nice for the ENWV-community to understand how and what files/contributions are deleted.
::note: @[[User:Koavf|Koavf]] @[[User:Juandev|Juandev]], @[[User:OhanaUnited|OhanaUnited]] as recent participants in the Colloquium I wonder if you have any knowledge to contribute?

:::This project is generally pretty policy-lite, so deleting talk pages is probably ad hoc and left to best judgement.

== Subscribing to this talk-page ==
Is anyone here curious to find out what is the best method of subscribing to discussions here? Until today I did not even know one could subscribe to all new topics by clicking on ''Subscribe'' (the second ''Action'' right after ''Move''). I will have to see if indeed I am automatically subscribed to this new thread that I am hoping to start as soon as I hit the ''Add topic'' blue button at the bottom right hand corner.
So far I have had to resort to clicking ''Subscribe'' individually for each topic when I wanted to receive a notification for any new replies, but unfortunately after some items I was subscribed to have been archived on January 30, I received a message telling me I am no longer subscribed. I guess I would have to look for any updates that took place before the archive in the archive itself?
Am I making sense at all? I have managed to confuse myself, LOL. [[User:Ottawahitech|Ottawahitech]] ([[User talk:Ottawahitech|discuss]] • [[Special:Contributions/Ottawahitech|contribs]]) 17:11, 30 January 2025 (UTC)
:You are not subscribed to threads once they are removed from a page (e.g. by archiving). The easiest way to subscribe is by clicking on the "Subscribe" button with the bell next to it that renders near the thread's title. —[[User:Koavf|Justin (<span style="color:grey">ko'''a'''vf</span>)]]<span style="color:red">❤[[User talk:Koavf|T]]☮[[Special:Contributions/Koavf|C]]☺[[Special:Emailuser/Koavf|M]]☯</span> 19:44, 30 January 2025 (UTC)

:Hi @[[User:Wüstenspringmaus|Wüstenspringmaus]], Looks like the RFC you started in an effort to globally ban [[User:Shāntián Tàiláng]] has still not concluded. Forgive me, but I am indef-blocked on META so cannot ask there:
:* Is there no time limit on such nominations?
:* I am not familiar with the subject of this ban nomination, but I think there might be some unsupported allegations against them, such as harassment which is a serious issue. If I'm wrong please forgive me, I did spend a lot of time plowing through this lengthy page.
:* Many of us prefer to spend more of our time adding information to the wiki-projects that we are involved in and less to endless discussions. The Nomination page on META is now '''43,962 bytes long''' and growing, and will require any new participant spend a great deal of unproductive time to come up to speed.
:Is it expectedad that the only people who Support or Oppose your nomination be personally familiar with the User in question? Cheers, [[User:Ottawahitech|Ottawahitech]] ([[User talk:Ottawahitech|discuss]] • [[Special:Contributions/Ottawahitech|contribs]]) 23:43, 16 February 2025 (UTC)

== Self-deleting pages that I nominated for deletion myself ==
In 2024, I nominated multiple pages for deletion via [[:Template:Proposed deletion]] (see also [[Special:WhatLinksHere/Template:Proposed deletion]]). The three-month protective period for most of them now expired.
Example pages: [[Astronomy outline]], [[VELS mathematics]], [[Particle mechanics]].
It would be ideal if the deleting person would be different from the nominating person. However, no one seems to be interested in deleting these pages.
Should I feel free to delete the pages I nominated myself? I think it could be okay, but I can also imagine someone being stringent about these matters and requiring the four-eye principle. One rationale for allowing deleting myself is that the English Wikiversity has only few active administrators and therefore, the four-eye principle would create too much of delay and overhead; on a more admin-populated project, the four-eye principle is more workable. --[[User:Dan Polansky|Dan Polansky]] ([[User talk:Dan Polansky|discuss]] • [[Special:Contributions/Dan Polansky|contribs]]) 06:08, 16 February 2025 (UTC)
:OK I'll bite :-)
:Looks like enwv has a different ''Proposed deletion'' notice than other wiki-projects. One thing I noticed immediately is that there is no reason or explanation required for the deletion proposal.
:I understand that all a deletion will accomplish is to remove those articles from public view. They will still continue to exist, but only admins will see them. May I ask @[[User:Dan Polansky|Dan Polansky]], why do you believe these 3 articles should be deleted? [[User:Ottawahitech|Ottawahitech]] ([[User talk:Ottawahitech|discuss]] • [[Special:Contributions/Ottawahitech|contribs]]) 23:08, 16 February 2025 (UTC)
:: I always provide a reason for deletion. And thus, e.g. [[Astronomy outline]] states: "The Nominator gave the following reason for their nomination:", "too low quality to serve as a learning resource; most links are redlinks; no further reading". --[[User:Dan Polansky|Dan Polansky]] ([[User talk:Dan Polansky|discuss]] • [[Special:Contributions/Dan Polansky|contribs]]) 09:18, 17 February 2025 (UTC)
: I went ahead and deleted the three listed pages. I will wait a little longer before I proceed further. Most of the usual admins do not seem to be around, though, so the absence of opposition does not tell us much. And thus, I am proceeding at risk, and undo is possible by an admin or quasi-admin. --[[User:Dan Polansky|Dan Polansky]] ([[User talk:Dan Polansky|discuss]] • [[Special:Contributions/Dan Polansky|contribs]]) 07:41, 24 February 2025 (UTC)
:@[[User:Dan Polansky|Dan Polansky]] You proposed deletion back in October. Yes, it's fine if you are now the one to delete it. Often there is only one user at a time interested in cleaning up Wikiversity. That person does it until they choose not to. Then after a while, someone else steps up. I cleaned up my own proposed deletions for years with very few complaints. If someone wants to object, they need to be willing to speak up and review your proposed deletions. -- [[User:Dave Braunschweig|Dave Braunschweig]] ([[User talk:Dave Braunschweig|discuss]] • [[Special:Contributions/Dave Braunschweig|contribs]]) 00:51, 26 February 2025 (UTC)

The [[foundation:|Wikimedia Foundation]] will switch the traffic between its data centers. This will make sure that Wikipedia and the other Wikimedia wikis can stay online even after a disaster.
All traffic will switch on '''{{#time:j xg|2025-03-19|en}}'''. The switch will start at '''[https://zonestamp.toolforge.org/{{#time:U|2025-03-19T14:00|en}} {{#time:H:i e|2025-03-19T14:00}}]'''.
Unfortunately, because of some limitations in [[mw:Special:MyLanguage/Manual:What is MediaWiki?|MediaWiki]], all editing must stop while the switch is made. We apologize for this disruption, and we are working to minimize it in the future.
A banner will be displayed on all wikis 30 minutes before this operation happens. This banner will remain visible until the end of the operation.
'''You will be able to read, but not edit, all wikis for a short period of time.'''
*You will not be able to edit for up to an hour on {{#time:l j xg Y|2025-03-19|en}}.
*If you try to edit or save during these times, you will see an error message. We hope that no edits will be lost during these minutes, but we can't guarantee it. If you see the error message, then please wait until everything is back to normal. Then you should be able to save your edit. But, we recommend that you make a copy of your changes first, just in case.
''Other effects'':
*Background jobs will be slower and some may be dropped. Red links might not be updated as quickly as normal. If you create an article that is already linked somewhere else, the link will stay red longer than usual. Some long-running scripts will have to be stopped.
* We expect the code deployments to happen as any other week. However, some case-by-case code freezes could punctually happen if the operation require them afterwards.
* [[mw:Special:MyLanguage/GitLab|GitLab]] will be unavailable for about 90 minutes.
This project may be postponed if necessary. You can [[wikitech:Switch_Datacenter|read the schedule at wikitech.wikimedia.org]]. Any changes will be announced in the schedule.

== Wikidata and Sister Projects: an online event ==
Hello everyone, I’m writing to announce an upcoming event called [[wikidata:Event:Wikidata and Sister Projects|'''Wikidata and Sister Projects''']] that will be a mini online conference to highlight the different ways Wikidata can be connected and integrated with the other WM projects.
We are currently looking for session ideas and speakers for our program and wanted to reach out in case there were any editors here that might have a cool idea for a session proposal. Sessions can be found on the [[wikidata:Event talk:Wikidata and Sister Projects|'''event discussion page''']].
As previously mentioned, we would like to showcase the relationship between Wikibooks and Wikidata, such as the storing of metadata and sitelinking between books and their respective Wikidata items. Do you have an idea for a session? We'd love to hear about it!
The event is scheduled between '''May 29 - June 1st, 2025'''. If you have any questions about the event, would like more information or have a session idea to propose, please feel free to get in touch by replying to this post or writing on the event page or on my [[v:User_talk:Danny_Benjafield_(WMDE)|talk page]].

== Names of pages I am creating, one man's look at X ==
I am creating pages like [[One man's look at LibreOffice]], but I am increasingly dissatisfied with this naming scheme. It just means that "One man's look at X" is nothing but "Dan Polansky's look at X"; what is so special about Dan Polansky that he is the "one man", which other people are not? I prefer "X (Dan Polansky)", but that was previously rejected (I should find the discussion, but I am too lazy now). What was not rejected is "X/Dan Polansky" (as in [[COVID-19/Dan Polansky]]), but I find it greatly suboptimal: there is nothing in that syntax that suggests that "Dan Polansky" is an author name; compare a possible "Philosophy/Aristotle", which would be ''about'' Aristotle and not ''by'' Aristotle.
Perhaps we can have a discussion/conversation about alternative proposals and what makes them preferable and dispreferable, desirable and undesirable? --[[User:Dan Polansky|Dan Polansky]] ([[User talk:Dan Polansky|discuss]] • [[Special:Contributions/Dan Polansky|contribs]]) 08:07, 1 May 2025 (UTC)
: If a main space page is meant only for one user's view, then perhaps that page should instead be located in that user's space. -- [[User:Jtneill|Jtneill]] - <small>[[User talk:Jtneill|Talk]] - [[Special:Contributions/Jtneill|c]]</small> 05:12, 17 May 2025 (UTC)
:: That would not work: pages in user space are not Google search indexed, from what I understand. One's spending effort to write and publish an article and then having it ignored by readers since not found via Google Search is not rewarding; I do not see why people would like to do it, and they apparently don't. Moreover, since other editors can comment on the article on the talk page, it is vital that the author does not have the right to have the article deleted on a whim; an article should be deleted only in well justified rare cases (ethical breach, etc.).
:: I think that a page being author-specific should be the usual case, not the rare case, in Wikiversity. It is the case with Wikijournal articles. It also seems to be the case with the Motivation and Emotion pages, e.g. as listed in [[Motivation and emotion/Book/2024]]; and thus, e.g. [[Motivation and emotion/Book/2024/Abusive supervision]] has TJDuus as the main author as per the assignment and revision history (there are auxiliary editors, but the author seems to maintain editorial control?)
:: Since Wikiversity pages are not organized by the principle of being encyclopedic and by avoidance of original research, I do not see how the free-for-all editing of Wikipedia could possibly work here.
:: Some of the best materials I have seen in the English Wikiversity either have a single author or single main author. --[[User:Dan Polansky|Dan Polansky]] ([[User talk:Dan Polansky|discuss]] • [[Special:Contributions/Dan Polansky|contribs]]) 08:10, 17 May 2025 (UTC)
== We will be enabling the new Charts extension on your wiki soon! ==
''(Apologies for posting in English)''
Hi all! We have good news to share regarding the ongoing problem with graphs and charts affecting all wikis that use them.
As you probably know, the [[:mw:Special:MyLanguage/Extension:Graph|old Graph extension]] was disabled in 2023 [[listarchive:list/wikitech-l@lists.wikimedia.org/thread/EWL4AGBEZEDMNNFTM4FRD4MHOU3CVESO/|due to security reasons]]. We’ve worked in these two years to find a solution that could replace the old extension, and provide a safer and better solution to users who wanted to showcase graphs and charts in their articles. We therefore developed the [[:mw:Special:MyLanguage/Extension:Chart|Charts extension]], which will be replacing the old Graph extension and potentially also the [[:mw:Extension:EasyTimeline|EasyTimeline extension]].
After successfully deploying the extension on Italian, Swedish, and Hebrew Wikipedia, as well as on MediaWiki.org, as part of a pilot phase, we are now happy to announce that we are moving forward with the next phase of deployment, which will also include your wiki.
The deployment will happen in batches, and will start from '''May 6'''. Please, consult [[:mw:Special:MyLanguage/Extension:Chart/Project#Deployment Timeline|our page on MediaWiki.org]] to discover when the new Charts extension will be deployed on your wiki. You can also [[:mw:Special:MyLanguage/Extension:Chart|consult the documentation]] about the extension on MediaWiki.org.
If you have questions, need clarifications, or just want to express your opinion about it, please refer to the [[:mw:Special:MyLanguage/Extension_talk:Chart/Project|project’s talk page on Mediawiki.org]], or ping me directly under this thread. If you encounter issues using Charts once it gets enabled on your wiki, please report it on the [[:mw:Extension_talk:Chart/Project|talk page]] or at [[phab:tag/charts|Phabricator]].
Thank you in advance! -- [[User:Sannita (WMF)|User:Sannita (WMF)]] ([[User talk:Sannita (WMF)|talk]]) 15:07, 6 May 2025 (UTC)

== Progressive translations ==
If you gradually translate more and more words in a text it's called "progressive translation" apparently. If we were doing, say, English to Hungarian it would look like "I took the ''vonat'' (train) to Budapest" and later on "I saw the river from the ''vonat''". I want to be able to read novels and pick up vocabulary in this way, as well as make them (or rather get an AI to make them) and share them with other language learners.
It's education so I thought you might be interested in hosting them, and maybe some people here would be interested in helping out.

== RfC ongoing regarding Abstract Wikipedia (and your project) ==
<div lang="en" dir="ltr" class="mw-content-ltr">
''(Apologies for posting in English, if this is not your first language)''
Hello all! We opened a discussion on Meta about a very delicate issue for the development of [[:m:Special:MyLanguage/Abstract Wikipedia|Abstract Wikipedia]]: where to store the abstract content that will be developed through functions from Wikifunctions and data from Wikidata. Since some of the hypothesis involve your project, we wanted to hear your thoughts too.
We want to make the decision process clear: we do not yet know which option we want to use, which is why we are consulting here. We will take the arguments from the Wikimedia communities into account, and we want to consult with the different communities and hear arguments that will help us with the decision. The decision will be made and communicated after the consultation period by the Foundation.
You can read the various hypothesis and have your say at [[:m:Abstract Wikipedia/Location of Abstract Content|Abstract Wikipedia/Location of Abstract Content]].

== Wikimedia Foundation Board of Trustees 2025 Selection & Call for Questions ==
<section begin="announcement-content" />
:''[[m:Special:MyLanguage/Wikimedia Foundation elections/2025/Announcement/Selection announcement|{{int:interlanguage-link-mul}}]] • [https://meta.wikimedia.org/w/index.php?title=Special:Translate&group=page-{{urlencode:Wikimedia Foundation elections/2025/Announcement/Selection announcement}}&language=&action=page&filter= {{int:please-translate}}]''
Dear all,
This year, the term of 2 (two) Community- and Affiliate-selected Trustees on the Wikimedia Foundation Board of Trustees will come to an end [1]. The Board invites the whole movement to participate in this year’s selection process and vote to fill those seats.
The Elections Committee will oversee this process with support from Foundation staff [2]. The Governance Committee, composed of trustees who are not candidates in the 2025 community-and-affiliate-selected trustee selection process (Raju Narisetti, Shani Evenstein Sigalov, Lorenzo Losa, Kathy Collins, Victoria Doronina and Esra’a Al Shafei) [3], is tasked with providing Board oversight for the 2025 trustee selection process and for keeping the Board informed. More details on the roles of the Elections Committee, Board, and staff are here [4].
Here are the key planned dates:
* May 22 – June 5: Announcement (this communication) and call for questions period [6]
* June 17 – July 1, 2025: Call for candidates
* July 2025: If needed, affiliates vote to shortlist candidates if more than 10 apply [5]
* August 2025: Campaign period
* August – September 2025: Two-week community voting period
* October – November 2025: Background check of selected candidates
* Board’s Meeting in December 2025: New trustees seated
Learn more about the 2025 selection process - including the detailed timeline, the candidacy process, the campaign rules, and the voter eligibility criteria - on this Meta-wiki page [[m:Special:MyLanguage/Wikimedia_Foundation_elections/2025|[link]]].
'''Call for Questions'''
In each selection process, the community has the opportunity to submit questions for the Board of Trustees candidates to answer. The Election Committee selects questions from the list developed by the community for the candidates to answer. Candidates must answer all the required questions in the application in order to be eligible; otherwise their application will be disqualified. This year, the Election Committee will select 5 questions for the candidates to answer. The selected questions may be a combination of what’s been submitted from the community, if they’re alike or related. [[m:Special:MyLanguage/Wikimedia_Foundation_elections/2025/Questions_for_candidates|[link]]]
'''Election Volunteers'''
Another way to be involved with the 2025 selection process is to be an Election Volunteer. Election Volunteers are a bridge between the Elections Committee and their respective community. They help ensure their community is represented and mobilize them to vote. Learn more about the program and how to join on this Meta-wiki page [[m:Wikimedia_Foundation_elections/2025/Election_volunteers|[link].]]

A covalent bond is a form of chemical bonding which is characterized by the sharing of electrons between atoms. Covalent bonds are mainly formed due to the tendency of the elements to attain a completely filled outer shell, that is, attain noble gas configuration and become stable.
Elements forming covalent compounds achieve noble gas configuration by sharing electrons within the atoms, unlike ionic compounds which achieve the noble gas configuration either by gaining or losing electrons from the outermost electron shell.
In covalent bonds, when two atoms are in need of extra electrons to fill their outer valence electron shell, they will often share an electron. The most common example that most people are familiar with is water. The oxygen in water forms a covalent bond with the hydrogen, thus filling the hydrogen's outer shell with two electrons (this is because the outer shell of hydrogen has a maximum capacity of two electrons). While an oxygen atom, originally having six outer electrons, now has seven valence electrons, it requires another in order to fill the shell, and so it bonds with another hydrogen to form H<sub>2</sub>O. Oxygen, thus has attained the configuration of the noble gas neon and the hydrogen atoms have obtained the configuration of the noble gas helium.
Covalent bonding does not produce electrons, it simply pairs them so that each atom has access to at least one more valence electron than before the bond.
Covalent bonding occurs between atoms with similar electronegativity, and thus most often occurs between non-metals. However, as there are sometimes uneven distributions of electronegativity, either one of the elements in any given compound may attract the shared electrons closer to it than the other one. Therefore, it will have more of a negative charge than the other (while the other becomes more positive). Though this is not a charge to the extent of ions when they gain/lose electrons, due to the slight charge, covalent compounds can produce ionic properties.
A simple way to understand the concept of a covalent bond is, <i>Co</i> can be taken as "co-operation" or "jointly" and <i>valence</i>, so ''covalent'' means the co-operation or joining of valence electrons.
==Types of Covalent Bonds==
The bonds formed by sharing of an electron pair between two atoms can typically be single, double or triple; that is, in covalent bonds, atoms may be linked together by single, double or triple bonds.However there is also quadruple covalent bond. In simplest terms, "single", "double", and "triple" refer to the number of shared electron pairs in the bond. For example, in the dioxygen (O<sub>2</sub>) molecule, each oxygen must share two of its electrons in order to obtain the noble gas configuration of 8 valence electrons, resulting in a double bond of two shared electron pairs. The ''valency'' of an atom is the maximum number of bonds it can form, usually the number of electrons required to reach a stable noble gas configuration (there are exceptions to this rule, called the ''octet rule'' as all noble gases except helium have 8 valence electrons, discussed further down). Each double bond counts as 2 bonds for this purpose, and each triple bond counts as 3.
Whether a bond is single, double, or triple is its ''bond order''.
=== <u>Single Covalent Bond</u> ===
In some molecules, a shared pair of electrons are contributed between the atoms, thus creating a "single bond". For example, in a hydrogen molecule, the two atoms of hydrogen are bonded together by a single bond.
How? The ''valency'' of hydrogen is 1, that is, the number of electrons present in the outermost shell is 1 and it needs 1 more electron to attain a noble gas configuration, that is a completely filled outer shell.
<big>'''H'''</big> has a valency of 1 and it needs 1 more electron to become stable.
So, it forms a bond with another hydrogen atom and shares its electron with it and the second hydrogen atom shares its 1 electron with the first one,
{{center top}}(<big>'''H'''</big>x) (x<big>'''H'''</big>){{center bottom}}
(Here, x shows the number of electrons present in the outer shell of a hydrogen atom.)
Now, the first atom shares its one electron with the second hydrogen atom and the second atom shares its one electron with the first one and thus we get one hydrogen atom.
{{center top}}(<big>'''H'''</big>(xx)<big>'''H'''</big>){{center bottom}}
Thus, 2 atoms of hydrogen share their electron to form a molecule of hydrogen, H<sub>2</sub>. This allows each hydrogen atom to attain the electronic configuration of the noble gas helium.
The shared pair of electrons is said to constitute a single bond within the two hydrogen atoms. It is a single bond because only one pair of electrons are shared within the hydrogen atoms. A single bond is denoted by a single line between the atoms. For example, the covalent bond in a hydrogen molecule is represented by:-
{{center top}}<big>'''H—H'''</big>{{center bottom}}
Such single covalent bond is also formed in chlorine molecule, Cl<sub>2</sub>.
=== <u>Double covalent bonds</u> ===
Sometimes, two atoms share two, not just one, electron pairs to attain a noble gas configuration, with each atom contributing two electrons for a total of four bonding electrons. The minimum valency of an atom that can participate in this kind of covalent bonding must have a minimum valence of 2.
<big>'''O'''</big> has a valency of 2, with 6 electrons, needing 2 more to become stable (although oxygen has 6 electrons, it has a valency of 2 because it only needs 2 more for stability). It therefore can form a ''double bond'' with another oxygen atom, with each atom keeping 4 of its electrons uninvolved in bonding and sharing 2 with the other atom.
{{center top}}(xxxx<big>'''O'''</big>xx) (xx<big>'''O'''</big>xxxx){{center bottom}}
thus becomes:
{{center top}}(xxxx<big>'''O'''</big>(xxxx)<big>'''O'''</big>xxxx){{center bottom}}
4 kept electrons plus 4 shared electrons then equals a stable 8-electron configuration.
A double bond is denoted by a doubled line between the bonding atoms:
{{center top}}<big>'''O=O'''</big>{{center bottom}}
Such a double bond is also found in the carbon dioxide molecule CO<sub>2</sub>:
{{center top}}(xxxx<big>'''O'''</big>(xxxx)<big>'''C'''</big>(xxxx)<big>'''O'''</big>xxxx){{center bottom}}
Here, each oxygen atom double-bonds to the carbon atom. The carbon atom has 4 valence electrons, and since it needs 4 more, it has a valency of 4, allowing it to form 2 double bonds (or 4 total bonds):
{{center top}}<big>'''O=C=O'''</big>{{center bottom}}
=== <u>Triple covalent bonds</u> ===
Likewise, when two atoms share three electron pairs, the bonding interaction is a ''triple bond.'' The minimum valency of an atom that can participate in this kind of bonding must be a minimum of 3.
<big>'''N'''</big> has a valency of 3, with 5 electrons, needing 3 more to become stable. It can form a triple bond with another nitrogen atom, with each atom sharing a total of 6 electrons with 2 unshared, making a full octet.
{{center top}}(xx<big>'''N'''</big>xxx) (xxx<big>'''N'''</big>xx){{center bottom}}
bonds to form:
{{center top}}(xx<big>'''N'''</big>(xxxxxx)<big>'''N'''</big>xx){{center bottom}}
A triple bond is denoted by three lines connecting the bonding atoms:
[[Image:Dinitrogen-2D-dimensions.png|50px|center|link=]]
==Exceptions to the octet rule==
Often one or more bonding atoms in a molecule do not satisfy the octet rule, even though the atom is stable with respect to its electron configuration.
For example, sulfur (<big>'''S'''</big>) has 6 valence electrons like oxygen. One might expect it to always share two to gain a noble gas configuration, but in sulfur hexafluoride (SF<sub>6</sub>), it shares all six of its valence electrons in single bonds with fluorine, thus ''exceeding'' the octet rule by 4 electrons:
[[Image:Sulfur-hexafluoride-2D-dimensions.svg|100px|center|link=]]
Likewise, sometimes an atom might have ''less'' than a full octet. Most elements that are not in the main groups (IA, IIA, IIIA-VIIA) don't follow the octet rule in this manner, and group IIIA elements also tend to have less than an octet.
Boron (<big>'''B'''</big>) has 3 valence electrons, needing either 5 more or 3 less to achieve a noble gas configuration. However, gaining 5 is not very easy (although it is possible, discussed later) while boron is too electronegative to fully lose all three.
Therefore, boron has a valency of 3 and shares all three valence electrons. However, other atoms can only share 3 total additional electrons with boron for a total of 6 - 2 short of the octet rule. Boron compounds of this kind are nevertheless stable. One example is boron trichloride (BCl<sub>3</sub>):
[[Image:Boron-trichloride-2D.svg|75px|center|link=]]
The third and least-common violation of the octet rule occurs for molecules where the total valence electron count is an odd number. This makes complete electron pairing impossible and it is not possible to achieve a full octet For example, nitrogen monoxide (NO) has a total of 11 valence electrons. Nitrogen and oxygen easily share two electrons each, but nitrogen still needs a third electron. Oxygen and nitrogen can then be said to be sharing a third electron contributed from oxygen that is unpaired. However, this is not a replacement for a full electron pair and this is not a triple bond. It is more than a double bond, though, and can be called a "2 and a half" bond, where the dashed line represents the "half-bond" (this terminology is not exactly correct but sufficient for this example):
[[Image:Nitric-oxide-2D.png|100px|center|link=]]
As might be expected from the presence of an unpaired electron, odd-number-electron molecules tend to be reactive, as they are made more stable if their unpaired electron is paired.
==Dative covalent bonds==
The bonding pair of electrons need not come from both atoms. In some cases a single atom supplies both electrons shared in a bond. In carbon monoxide (CO), oxygen has 6 valence electrons and carbon 4 valence electrons. If each atom shares two electrons each, then oxygen satisfies the octet rule but carbon is still in need of two.
{{center top}}(xx<big>'''C'''</big>xx) (xx<big>'''O'''</big>xx{{font|color=green|xx}}){{center bottom}}
{{center top}}(xx<big>'''C'''</big>(xxxx)<big>'''O'''</big>xx{{font|color=green|xx}}){{center bottom}}
Oxygen thus will share two more of its electrons with carbon, forming an additional bond with the pair of electrons entirely contributed from oxygen. This bond is a ''dative'' covalent bond. The electrons in question are highlighted in green.
{{center top}}(xx<big>'''C'''</big>(xxxx{{font|color=green|xx}})<big>'''O'''</big>xx){{center bottom}}
This additional bond adds on to the two bonds already made, so this is a triple bond, albeit an unusual one where the atoms don't make equal contributions to the bonding. It is represented like any other triple bond:
[[Image:Carbon_monoxide_2D.svg|100px|center|link=]]
Dative covalent bonds can also allow boron to achieve a complete octet. Boron trifluoride, with the same structure as boron trichloride (mentioned above), can react with ammonia (NH<sub>3</sub>), where nitrogen has 2 unshared electrons. The boron atom can link up to nitrogen in a dative covalent bond using those electrons:

Cannabis, commonly known as '''marijuana''', is a preparation of the cannabis plant intended for use as a psychoactive drug and as medicine. Cannabis is often consumed for its psychoactive and physiological effects, which can include heightened mood or euphoria, relaxation, and an increase in appetite. Unwanted side-effects can sometimes include a decrease in short-term memory, dry mouth, impaired motor skills, reddening of the eyes, and feelings of paranoia or anxiety.<ref>[[Wikipedia: Cannabis (drug)]]

'''<big><noinclude>Diverse Categories of Computer Software: An Ultimate Guide</big>'''
In today’s technology-driven world, computer software plays a critical role in both personal and professional environments. From writing documents and editing photos to managing entire businesses, software is the digital brain behind modern computing. But not all software is the same. To truly understand how technology works, you need to explore the diverse categories of computer software and how they function.
This ultimate guide breaks down the major types of computer software, their roles, examples, and why they matter.
== What is Computer Software? ==
=== <small>Computer software is a set of instructions or programs that tell a computer how to perform specific tasks. Unlike hardware, which is the physical component of a computer, software is intangible but essential for operations.</small> ===
== '''There are two primary classifications of software:''' ==
# System Software
# Application Software
Beyond these, several specialized categories exist, each designed for specific functionalities.
----
== '''1. System Software''' ==
System software serves as the foundation for all other software. It manages hardware components and provides a platform for running application software.
=== Key Subtypes of System Software: ===
* '''Operating Systems (OS)''' Examples: Windows, macOS, Linux Purpose: Manages hardware resources and provides a user interface.
* '''Device Drivers''' Examples: Printer drivers, graphic card drivers Purpose: Enables communication between hardware and the operating system.
* '''Utility Programs''' Examples: Antivirus software, Disk Cleanup tools Purpose: System maintenance and performance optimization.
----
== '''2. Application Software''' ==
Application software allows users to perform specific tasks like writing, designing, or browsing the internet.
=== Types of Application Software: ===
* '''Productivity Software''' Examples: Microsoft Word, Excel, Google Docs Use: Word processing, data analysis, and presentation creation.
* '''Multimedia Software''' Examples: Adobe Photoshop, VLC Media Player Use: Creating and viewing images, videos, and audio.
* '''Web Browsers''' Examples: Google Chrome, Firefox Use: Accessing and navigating the internet.
* '''Communication Tools''' Examples: Zoom, Microsoft Teams, Slack Use: Real-time messaging, video conferencing, and collaboration.
* '''Business Software''' Examples: CRM software, accounting tools like QuickBooks Use: Managing business operations, customer relationships, and finance.
----
== '''3. Programming Software''' ==
Programming software provides tools for developers to write, test, and maintain code. It's essential for software development.
=== Examples: ===
* '''Text Editors''': Notepad++, Sublime Text
* '''Compilers''': GCC, Visual C++
* '''Debuggers''': GDB, LLDB
* '''IDEs (Integrated Development Environments)''': Eclipse, Visual Studio, IntelliJ IDEA
These tools help software developers build applications, test them, and deploy robust solutions.
----
== '''4. Web-Based Software''' ==
Also known as Software as a Service (SaaS), web-based software is hosted in the cloud and accessed via a web browser.
=== Examples: ===
* Google Workspace (Docs, Sheets, Gmail)
* Salesforce CRM
* Canva
* Trello
=== Advantages: ===
* No installation required
* Automatic updates
* Accessible from anywhere with an internet connection
----
== '''5. Commercial vs Freeware vs Open Source''' ==
There are also different licensing models that define how software can be used, modified, and distributed.
=== Commercial Software: ===
* Paid software developed for profit
* Example: Adobe Photoshop, Microsoft Office
=== Freeware: ===
* Free to use but not to modify or redistribute
* Example: Skype, Avast Antivirus
=== Open Source: ===
* Free to use, modify, and share
* Example: Linux OS, GIMP, LibreOffice
Open-source software plays a vital role in innovation and is popular among developers and startups.
----
== '''6. Mobile Software''' ==
With the rise of smartphones, mobile apps have emerged as a significant software category.
=== Types of Mobile Software: ===
* '''Native Apps''' (specific to OS): iOS apps from Apple Store, Android apps from Play Store
* '''Cross-platform Apps''': Developed using frameworks like Flutter or React Native
* '''Mobile Games''': Examples: Candy Crush, PUBG Mobile
----
== '''7. Security Software''' ==
Security software protects devices from malware, viruses, and other cyber threats.
=== Examples: ===
* Antivirus (e.g., Norton, Kaspersky)
* Firewalls
* Anti-spyware
* VPNs
It’s a crucial category as cyberattacks grow more sophisticated.
----
== '''8. Artificial Intelligence (AI) Software''' ==
A growing field, AI software mimics human intelligence and is used in machine learning, natural language processing, and robotics.
=== Examples: ===
* ChatGPT (like you're reading now)
* TensorFlow (AI development framework)
* IBM Watson
* AI-powered CRM tools
----
== '''9. Enterprise Software''' ==
Enterprise software is designed for large organizations to manage internal operations and external relationships.
=== Examples: ===
* ERP systems (SAP, Oracle)
* HRMS tools (Workday, Zoho People)
* Supply Chain Management systems
Most of these are developed by a '''[https://niotechone.com/services/software-development-company/ custom software development company]''' offering software development services to enterprises.
----
== '''10. Custom Software''' ==
Sometimes, off-the-shelf solutions don’t meet specific business needs. That’s where '''[https://niotechone.com/services/software-development-company/ custom software development services]''' come in.
=== '''Why Choose Custom Software?''' ===
* Tailored to your workflow
* Scalable for future needs
* Secure and optimized for performance
=== Delivered By: ===
* A professional software development company
* Experts who '''[https://niotechone.com hire software developers]''' to build robust, secure, and scalable solutions
----
== '''Final Thoughts''' ==
As technology evolves, so does software. From operating systems to AI applications, the world of software is vast, diverse, and essential for daily functioning. Whether you’re an end-user or a business decision-maker, understanding these categories can help you choose the right tools and strategies.
If you're looking to build a tailored solution for your business, consider reaching out to a trusted '''[https://niotechone.com custom software development company]''' that offers end-to-end software development services. They’ll help transform your vision into scalable, secure, and intelligent software.{{wjm_h2|Creation and submission of preprints}}

== Overview ==
=== Algernon Bourke ===
Although the Hon. Algernon Henry Bourke was born in Dublin in 1854 and came from a family whose title is in the Peerage of Ireland,<ref name=":6">1911 England Census.</ref> he seems to have spent much of his adult life generally in England and especially in London. He was "a noted fisherman."<ref>"London Correspondence." ''Freeman's Journal'' 21 December 1897, Tuesday: 5 [of 8], Col. 5c [of 9]. ''British Newspaper Archive'' https://www.britishnewspaperarchive.co.uk/viewer/bl/0000056/18971221/027/0005. Same print title, n.p.</ref>
Because he was the son of the [[Social Victorians/People/Mayo|Earl of Mayo]], perhaps, or perhaps because he was so involved in projects that got reported on, he was mentioned a great deal in the newspapers, but after his bankruptcy, he seems to have receded in prominence, in part because he was living outside of the U.K., and apparently separately from his wife, Gwendolen Bourke.
Bourke ran as the Conservative candidate for Parliament from Clapham (population, c. 70,000) in 1885, a race he did not win. As a candidate he is described like this:<blockquote>Acted as a newspaper correspondent during the Zulu war. Subsequently Poor-law inspector in the West of Ireland. "A loyal supporter of Church and State." Desires to reduce the School Board expenditure, and revive trade; and is opposed to Mr. Chamberrlain's "police of hasty and experimental reform."<ref>"Clapham (70,000)." ''South London Chronicle'' 17 October 1885, Saturday: 5 [of 8], Col. 5a [of 6]. ''British Newspaper Archive'' https://www.britishnewspaperarchive.co.uk/viewer/bl/0000443/18851017/113/0005. Print title ''South London Chronicle and Southwark and Lambeth Ensign'', p. 5.</ref></blockquote>The London ''Weekly Dispatch'' says he is "a dashing and unscrupulous young Tory."<ref>"The Political Campaign in London." ''Weekly Dispatch'' (London) 15 November 1885, Sunday: 9 [of 16], Col. 3c [of 4]. ''British Newspaper Archive'' https://www.britishnewspaperarchive.co.uk/viewer/bl/0003358/18851115/069/0009. Same print title and p.</ref>
"Algy" Bourke was "Man of the Day" (No. DCCII [522) for ''Vanity Fair'' in 1898, caricatured by Leslie Ward (above right):<blockquote>Son of the great and murdered Lord Mayo, he is contemporary with the outbreak of the Crimean War, he is a Member of the London Stock Exchange, he has a beautiful wife and a daughter, and, being a very fashionable young man, he was once refused as their Member by the worthy electors of Clapham. He was an Eton boy, of course: and less naturally he went to Cambridge; where he was made President of the Beefsteak, the Amateur Dramatic, the Athenaeum, the True Blue, and the Hibernian Clubs. When he came down he tried journalism and went to Zululand as a ''Daily Telegraph'' ‘‘special”; after which he was improved into an Inspector of Workhouses [2, Col. 2c – 3, Col. 1a] in Ireland: which may account for his proficiency as a caterer. For seven years he worked under the late Mr. Chinnery on ''The Times'': being popularly supposed to look after that journal's morals. He is a good man of business, and a great organiser who has made White's Club pay even if it be less “smart" than it was. He has done much for Willis’s since he took it in hand; he did well with his Battersea venture, and he thinks that he only failed with the Summer Club in Kensington Gardens because people would not go to the wrong side of the Park. Moreover, he runs a Club at Brighton, and he is Chairman of the Grand Hotel at Monte Carlo: whither he once organised a cheap trip. Altogether he is a veritable Clubman, and a very successful arranger of amusements, associations, and restaurants.
He is a popular fellow who is known to all of us; and though he is a little inclined to be quarrelsome, no one can get much the better of him. He is also a quick grasper of facts and a good talker. His favourite sports are fishing and the organising of associations for the introduction of salmon to the Thames. By way of being an art critic, he has made an interesting collection of engravings of the members of White’s Club from its foundation; but his friends say that he is not a well-dressed man. He has also written a history of White’s, and he is now writing one of Brooks's Club. He is a genial person, who looks as if the world agreed with him well.
He is an aquisition [sic] to a house party; and they call him “Algy.”<ref>"Men of the Day." — No. DCCII [522]. The Hon. Algernon Henry Bourke." ''Vanity Fair'' 20 January 1898, Thursday: 2 [of 4], Col. 2c – 3, Col. 3a. ''British Newspaper Archive'' https://www.britishnewspaperarchive.co.uk/viewer/bl/9900020/18980120/010/0002 and https://www.britishnewspaperarchive.co.uk/viewer/BL/9900020/18980120/005/0003. Same print title, pp. 41–42. Portrait is full page, on p. 1.</ref></blockquote>The Hon. Algernon Bourke and Mr. Algernon Bourke, depending on the newspaper article, were the same person. Calling him Mr. Bourke in the newspapers, especially when considered as a businessman or (potential) member of Parliament, does not rule out the son of an earl, who would normally be accorded the honorific of ''Honorable''.
=== Gwendolen Sloane-Stanley Bourke ===
Mrs. Gwendolen Bourke exhibited at dog shows successfully and was a [[Social Victorians/Timeline/1900s#Society Sportswomen|noted deerstalker]] and "an appreciative listener to good music."<ref>"Vanity Fair." ''Lady of the House'' 15 June 1899, Thursday: 4 [of 44], Col. 2c [of 2]. ''British Newspaper Archive'' https://www.britishnewspaperarchive.co.uk/viewer/bl/0004836/18990615/019/0004.</ref> Her personal beauty is often mentioned in reports, and ''The World'' says she was "a magnificent woman."<ref>"Beauties of To-Day. From the ''World''." ''Clifton Society'' 24 June 1897, Thursday: 14 [of 16], Col. 2c [of 3]. ''British Newspaper Archive'' https://www.britishnewspaperarchive.co.uk/viewer/bl/0002164/18970624/066/0014. Same print and p.</ref> She is the first listed in the ''Graphic''<nowiki/>'s 1891 "Leading Ladies of Society":<blockquote>The Hon. Mrs. Algernon Bourke is a daughter (Gwendoline Irene Emily) of the late Hans Sloane Stanley, Esq., of Poultons, Southampton, and 49, Cadogan Square, S.W. She married, on December 15th, 1887, the Hon. Algernon Bourke, third son of the sixth Earl of Mayo, Governor-General of India (who was assassinated in 1872), and nephew of Lord Connemara, Governor of Madras. Mr. Bourke is a member of the London Stock Exchange, and resides at 33, Cadogan Terrace, S.W.<ref>"Leading Ladies of Society." The Graphic 28 March 1891, Saturday: 6 [of 28], Col. 2c [of 3]. British Newspaper Archive https://www.britishnewspaperarchive.co.uk/viewer/bl/9000057/18910328/019/0006. Print: same title, p. 346.</ref></blockquote>She attended many social events without her husband, especially into the 20th century, usually with an appreciative description of what she wore. She was a sponsor of Irish art needlework as well. Unlike her husband's, Gwendolen's social status seems to have risen as time passed, and she appears in stories associated with the Princess of Wales, and then later with Queen Alexandra.
=== The Sloane-Stanley Family ===
Gwendolen's family consisted of a younger brother, Cyril Sloane-Stanley, as well as her parents, Hans Sloane-Stanley and Emilie Edwards Sloane-Stanley. Exactly one year after she and Algernon Bourke married, Hans Sloane-Stanley died (in 1888), leaving an estate worth £33,704 7s. 5d.<ref name=":17">Principal Probate Registry; London, England; ''Calendar of the Grants of Probate and Letters of Administration made in the Probate Registries of the High Court of Justice in England''. Ancestry.com. ''England & Wales, National Probate Calendar (Index of Wills and Administrations), 1858-1995'' [database on-line]. Lehi, UT, USA: Ancestry.com Operations, Inc., 2010.</ref> (1888, 321) Her mother remarried almost exactly a year after that, to James Shelly Bontein. Bontein's father had been Gentleman Usher and Clerk of the Robes to Queen Victoria.<ref name=":18">"Marriages." "Births, Marriages, and Deaths." ''Belfast News-Letter'' 6 December 1889, Friday: 1 [of 8], Col. 1a [of 8]. ''British Newspaper Archive'' https://www.britishnewspaperarchive.co.uk/viewer/bl/0000038/18891206/001/0001. Same print title and p.</ref>
Shortly after his death ''Truth'' described Gwendolen and Cyril's father Hans Sloane-Stanley:<blockquote>The death of Mr. Sloane Stanley, of Paultons Park, is much regretted in South Hants, as he was one of the most popular landlords in the county, and was greatly esteemed. Mr. Sloane Stanley was well known in yachting circles, and for many years he was Commodore of the Royal Southern Yacht Club, and owned the schooner ''Star of the West''. He was one of the very few owners who continued to keep up the old custom of giving his crew a laying-up supper at the close of each season. There were great festivities at Paultons only a few months ago, when Miss Sloane Stanley was married to Mr. Algernon Bourke.<ref>"Entre Nous." ''Truth'' 27 December 1888, Thursday: 6 [of 48], Col. 2b [of 2]. ''British Newspaper Archive'' [https://www.britishnewspaperarchive.co.uk/viewer/bl/0002961/18881227/023/0006# https://www.britishnewspaperarchive.co.uk/viewer/bl/0002961/18881227/023/0006]. Same print title, p. 1136.</ref></blockquote>When he died in 1944, Cyril Sloane-Stanley's estate was quite a bit larger than his father's had been 50 years before. The probate was divided between what was limited to "settled land" and what was "save and except settled land." What was not settled land totalled £356,114 12s. 10d. and went to John Everett, company director; the Hon. Elwyn Villiers Rhys, captain, H.M. army; and William Adam de Geijer, retired captain, H.M. army.<ref name=":17" /> (1944, 430) His daughter Lavender was married to John Everett, and Diane was married to Elwyn Villiers Rhys. What was settled land totalled £168,975 and went to William Adam de Geijer, retired captain, H.M. army, and George Lawrence Stewart, solicitor.<ref name=":17" /> (1944, 430)
The Sloane-Stanleys descend from Hans Sloane (1660–1753), whose 71,000-item collections "provid[ed] the foundation of the British Museum, the British Library, and the Natural History Museum, London."<ref name=":19">{{Cite journal|date=2025-01-07|title=Hans Sloane|url=https://en.wikipedia.org/wiki/Hans_Sloane|journal=Wikipedia https://en.wikipedia.org/wiki/Hans_Sloane|language=en|via=}}</ref> Much of this Hans Sloane's wealth came from his medical practice as and from Jamaica, where he went as physician to the Governor General of Jamaica, the 2nd Duke of Albemarle, and where he married "a wealthy heiress of sugar plantations" worked by enslaved Jamaicans.<ref name=":19" /> His great-nephew, Hans Sloane, inherited Paultons, near Romsey, "and in recognition of this he adopted the additional surname of Stanley in 1821."<ref>{{Cite journal|date=2023-10-06|title=Hans Sloane (MP)|url=https://en.wikipedia.org/wiki/Hans_Sloane_(MP)|journal=Wikipedia https://en.wikipedia.org/wiki/Hans_Sloane_(MP)|language=en}}</ref>

(From the ''World''.)
The marriage of "Mr. Manton" was the surprise as well the sensation of last week. Although some wise people noticed a certain amount of youthful ardour in the attentions paid by Mr. Marcus Henry Milner to Caroline Duchess of Montrose at '''Mrs. Oppenheim's ball''', nobody was prepared for the sudden ''dénouement''; '''and it''' were not for the accidental and unseen presence [[Social Victorians/People/Mildmay|a well-known musical amateur]] who had received permission to practice on the organ, the ceremony performed at half-past nine on Thursday morning at St. Andrew's, Fulham, by the Rev. Mr. Propert, would possibly have remained a secret for some time to come. Although the evergreen Duchess attains this year the limit of age prescribed the Psalmist, the bridegroom was only born in 1864. Mr. "Harry" Milner (familiarly known in the City as "Millions") was one of the zealous assistants of that well-known firm of stockbrokers, Messrs. Bourke and Sandys, and Mr. Algernon Bourke, the head of the house (who, of course, takes a fatherly interest in the match) went down to Fulham to give away the Duchess. The ceremony was followed by a ''partie carrée'' luncheon at the Bristol, and the honeymoon began with a visit to the Jockey Club box at Sandown. Mr. Milner and the Duchess of Montrose have now gone to Newmarket. The marriage causes a curious reshuffling of the cards of affinity. Mr. Milner is now the stepfather of the [[Social Victorians/People/Montrose|Duke of Montrose]], his senior by twelve years; he is also the father-in-law of [[Social Victorians/People/Lady Violet Greville|Lord Greville]], Mr. Murray of Polnaise, and [[Social Victorians/People/Breadalbane|Lord Breadalbane]].<ref name=":8" /></blockquote>

He walked through the centre door with his suite, and was immediately conducted by Canon Newbolt to General Gordon’s tomb in the north aisle, where a detachment of boys from the Gordon Home received him as a guard of honor.
Li inspected the monument with marked interest, and drew the attention of his suite to the remarkable likeness to the dead hero. He laid a handsome wreath of royal purple asters, lilies, maidenhair fern, and laurel, tied with a broad band of purple silk, on the tomb.

Li Hung Chang has five native cooks in his retinue, and the greatest good fellowship exists between them and their English ''confreres'', although considerable difficulty is experienced in conversation in understanding one another's meaning.

The greater portion of the club property had already been removed to the new premises, but Mr Algernon Bourke, his private secretary, and some of the officials of the club, still occupied bed-rooms at the house in the King’s-road. The corner shop of the street front is occupied by Mr. Marx, a jeweller in a large way of business, and upon his manager arriving at nine o'clock he discovered that the place had been entered through hole in the ceiling, and a great part of a very valuable stock of jewelry extracted. An examination of the morning rooms of the club, which runs over Mr. Marx's establishment reveal a singularly neat specimen of the burglar's art. A piece of the flooring about 15in square had been removed by a series of holes bored side by side with a centre-bit, at a spot where access to the lofty shop was rendered easy by a tall showcase which stood convemently near. A massive iron girder had been avoided by a quarter of an inch, and this circumstance and the general finish of the operation point to an artist in his profession, who had acquired an intimate knowledge of the premises. The club doors were all found locked yesterday morning, and the means of egress adopted by the thief are at present a mystery.<ref>"Burglary at Brighton."

Besides the two that mention her — the ''Morning Post'' and the ''Times'' — only two describe her costume, the London ''Evening Standard'' and the ''Gentlewoman'':
* "Mrs. A. Bourke, as an Egyptian Princess, with the Salambo coiffure, wore a flowing gown of white and silver gauze covered with embroidery of lotus flowers. The top of the gown was ornamented with old green satin embroidered with blue turquoise and gold, and studded with rubies.

==== Salammbô ====
Salammbô is the eponymous protagonist in Gustave Flaubert's 1862 novel.<ref name=":5">{{Cite journal|date=2024-04-29|title=Salammbô|url=https://en.wikipedia.org/w/index.php?title=Salammb%C3%B4&oldid=1221352216|journal=Wikipedia|language=en}} https://en.wikipedia.org/wiki/Salammb%C3%B4.</ref> Ernest Reyer's opera ''Salammbô'' was based on Flaubert's novel and published in Paris in 1890 and performed in 1892<ref>{{Cite journal|date=2024-04-11|title=Ernest Reyer|url=https://en.wikipedia.org/w/index.php?title=Ernest_Reyer&oldid=1218353215|journal=Wikipedia|language=en}} https://en.wikipedia.org/wiki/Ernest_Reyer.</ref> (both Modest Mussorgsky and Sergei Rachmaninoff had attempted but not completed operas based on the novel as well<ref name=":5" />). Alfons Mucha's 1896 lithograph of Salammbô was published in 1896, the year before the ball (above left).[[File:Algernon Henry Bourke Vanity Fair 20 January 1898.jpg|thumb|alt=Old colored drawing of an elegant elderly man dressed in a 19th-century tuxedo with a cloak, top hat and formal pointed shoes with bows, standing facing 1/4 to his right|''Algy'' — Algernon Henry Bourke — by "Spy," ''Vanity Fair'' 20 January 1898]]

'''Lafayette's portrait''' (left) of "Hon. Algernon Henry Bourke as Izaak Walton" in costume is photogravure #129 in the album presented to the Duchess of Devonshire and now in the National Portrait Gallery.<ref name=":4" /> The printing on the portrait says, "The Hon.

National Portrait Gallery https://www.npg.org.uk/collections/search/portrait/mw158492/Hon-Algernon-Henry-Bourke-as-Izaak-Walton.</ref>
This portrait is amazing and unusual: Algernon Bourke is not using a photographer's set with theatrical flats and props, certainly not one used by anyone else at the ball itself. Isaak Walton (baptised 21 September 1593 – 15 December 1683) wrote ''The Compleat Angler''.<ref>{{Cite journal|date=2021-09-15|title=Izaak Walton|url=https://en.wikipedia.org/w/index.php?title=Izaak_Walton&oldid=1044447858|journal=Wikipedia|language=en}} https://en.wikipedia.org/wiki/Izaak_Walton.</ref> A cottage Walton lived in and willed to the people of Stafford was photographed in 1888, suggesting that its relationship to Walton was known in 1897, raising a question about whether Bourke could have used the fireplace in the cottage for his portrait. (This same cottage still exists, as the [https://www.staffordbc.gov.uk/izaak-waltons-cottage Isaak Walton Cottage] museum.)
A caricature portrait (right) of the Hon. Algernon Bourke, called "Algy," by Leslie Ward ("Spy") was published in the 20 January 1898 issue of ''Vanity Fair'' as Number 702 in its "Men of the Day" series,<ref>{{Cite journal|date=2024-01-14|title=List of Vanity Fair (British magazine) caricatures (1895–1899)|url=https://en.wikipedia.org/w/index.php?title=List_of_Vanity_Fair_(British_magazine)_caricatures_(1895%E2%80%931899)&oldid=1195518024|journal=Wikipedia|language=en}} https://en.wikipedia.org/wiki/List_of_Vanity_Fair_(British_magazine)_caricatures_(1895%E2%80%931899).</ref> giving an indication of what he looked like out of costume.

== Notes and Questions ==
#The portrait of Algernon Bourke in costume as Isaac Walton is really an amazing portrait with a very interesting setting, far more specific than any of the other Lafayette portraits of these people in their costumes. Where was it shot? Lafayette is given credit, but it's not one of his usual backdrops. If this portrait was taken the night of the ball, then this fireplace was in Devonshire House; if not, then whose fireplace is it?
#The ''Times'' lists Hon. A. Bourke (at 325) and Hon. Mrs. A. Bourke (at 236) as members of a the "Oriental" procession, Mr. and Mrs. A. Bourke (in the general list of attendees), and then a small distance down Mr. and Mrs. Bourke (now at 511 and 512, respectively). This last couple with no honorifics is also mentioned in the report in the London ''Evening Standard'', which means the Hon. Mrs. A. Bourke, so the ''Times'' may have repeated the Bourkes, who otherwise are not obviously anyone recognizable. If they are not the Hon. Mr. and Mrs. A. Bourke, then they are unidentified. It seems likely that they are the same, however, as the newspapers were not perfectly consistent in naming people with their honorifics, even in a single story, especially a very long and detailed one in which people could be named more than once.
#Three slightly difficult-to-identify men were among the Suite of Men in the [[Social Victorians/1897 Fancy Dress Ball/Quadrilles Courts#"Oriental" Procession|"Oriental" procession]]: [[Social Victorians/People/Halifax|Gordon Wood]], [[Social Victorians/People/Portman|Arthur B. Portman]] and [[Social Victorians/People/Sarah Spencer-Churchill Wilson|Wilfred Wilson]]. The identification of Gordon Wood and Wilfred Wilson is high because of contemporary newspaper accounts. The Hon. Algernon Bourke, who was also in the Suite of Men, is not difficult to identify at all. Arthur Portman appears in a number of similar newspaper accounts, but none of them mentions his family of origin.
#[http://thepeerage.com The Peerage] has no other Algernon Bourkes.
#The Hon Algernon Bourke is #235 on the [[Social Victorians/1897 Fancy Dress Ball#List of People Who Attended|list of people who were present]]; the Hon. Guendoline Bourke is #236; a Mr. Bourke is #703; a Mrs. Bourke is #704.
#Hans Stanley-Sloane's estate was £33,704 7s. 5d. in the final probate in December 1889,<ref>Principal Probate Registry; London, England; ''Calendar of the Grants of Probate and Letters of Administration made in the Probate Registries of the High Court of Justice in England''.

Algernon Henry Bourke was born in Dublin in 1854 and came from a family whose title is in the Peerage of Ireland,<ref name=":6">1911 England Census.</ref> he seems to have spent much of his adult life generally in England and especially in London. He was "a noted fisherman."<ref>"London Correspondence." ''Freeman's Journal'' 21 December 1897, Tuesday: 5 [of 8], Col. 5c [of 9].

Because he was the son of the [[Social Victorians/People/Mayo|Earl of Mayo]], perhaps, or perhaps because he was so involved in projects that got reported on, he was mentioned a great deal in the newspapers, but after his bankruptcy, he seems to have receded in prominence, in part because he was living outside of the U.K., and apparently separately from his wife, Gwendolen Bourke.
Bourke ran as the Conservative candidate for Parliament from Clapham (population, c. 70,000) in 1885, a race he did not win. As a candidate he is described like this:<blockquote>Acted as a newspaper correspondent during the Zulu war. Subsequently Poor-law inspector in the West of Ireland. "A loyal supporter of Church and State." Desires to reduce the School Board expenditure, and revive trade; and is opposed to Mr. Chamberlain's "police of hasty and experimental reform."<ref>"Clapham (70,000)."

"Algy" Bourke was "Man of the Day" (No. DCCII [522) for ''Vanity Fair'' in 1898, caricatured by Leslie Ward (above right):<blockquote>Son of the great and murdered Lord Mayo, he is contemporary with the outbreak of the Crimean War, he is a Member of the London Stock Exchange, he has a beautiful wife and a daughter, and, being a very fashionable young man, he was once refused as their Member by the worthy electors of Clapham. He was an Eton boy, of course: and less naturally he went to Cambridge; where he was made President of the Beefsteak, the Amateur Dramatic, the Athenaeum, the True Blue, and the Hibernian Clubs. When he came down he tried journalism and went to Zululand as a ''Daily Telegraph'' ‘‘special”; after which he was improved into an Inspector of Workhouses [2, Col. 2c – 3, Col. 1a] in Ireland: which may account for his proficiency as a caterer. For seven years he worked under the late Mr. Chinnery on ''The Times'': being popularly supposed to look after that journal's morals. He is a good man of business, and a great organiser who has made White's Club pay even if it be less “smart" than it was. He has done much for Willis’s since he took it in hand; he did well with his Battersea venture, and he thinks that he only failed with the Summer Club in Kensington Gardens because people would not go to the wrong side of the Park. Moreover, he runs a Club at Brighton, and he is Chairman of the Grand Hotel at Monte Carlo: whither he once organised a cheap trip. Altogether he is a veritable Clubman, and a very successful arranger of amusements, associations, and restaurants.
He is a popular fellow who is known to all of us; and though he is a little inclined to be quarrelsome, no one can get much the better of him. He is also a quick grasper of facts and a good talker. His favourite sports are fishing and the organising of associations for the introduction of salmon to the Thames. By way of being an art critic, he has made an interesting collection of engravings of the members of White’s Club from its foundation; but his friends say that he is not a well-dressed man. He has also written a history of White’s, and he is now writing one of Brooks's Club. He is a genial person, who looks as if the world agreed with him well.
He is an aquisition [sic] to a house party; and they call him “Algy.”<ref>"Men of the Day." — No. DCCII [522]. The Hon. Algernon Henry Bourke."

Calling him Mr. Bourke in the newspapers, especially when considered as a businessman or (potential) member of Parliament, does not rule out the son of an earl, who would normally be accorded the honorific of ''Honorable''.

She was a sponsor of Irish art needlework as well. Unlike her husband's, Gwendolen's social status seems to have risen as time passed, and she appears in stories associated with the Princess of Wales, and then later with Queen Alexandra.
=== The Sloane-Stanley Family ===
Gwendolen's family consisted of a younger brother, Cyril Sloane-Stanley, as well as her parents, Hans Sloane-Stanley and Emilie Edwards Sloane-Stanley. Exactly one year after she and Algernon Bourke married, Hans Sloane-Stanley died (in 1888), leaving an estate worth £33,704 7s. 5d.<ref name=":17">Principal Probate Registry; London, England; ''Calendar of the Grants of Probate and Letters of Administration made in the Probate Registries of the High Court of Justice in England''.

Shortly after his death ''Truth'' described Gwendolen and Cyril's father Hans Sloane-Stanley:<blockquote>The death of Mr. Sloane Stanley, of Paultons Park, is much regretted in South Hants, as he was one of the most popular landlords in the county, and was greatly esteemed. Mr. Sloane Stanley was well known in yachting circles, and for many years he was Commodore of the Royal Southern Yacht Club, and owned the schooner ''Star of the West''. He was one of the very few owners who continued to keep up the old custom of giving his crew a laying-up supper at the close of each season. There were great festivities at Paultons only a few months ago, when Miss Sloane Stanley was married to Mr. Algernon Bourke.<ref>"Entre Nous."

Same print title, p. 1136.</ref></blockquote>When he died in 1944, Cyril Sloane-Stanley's estate was quite a bit larger than his father's had been 50 years before. The probate was divided between what was limited to "settled land" and what was "save and except settled land." What was not settled land totalled £356,114 12s. 10d. and went to John Everett, company director; the Hon. Elwyn Villiers Rhys, captain, H.M. army; and William Adam de Geijer, retired captain, H.M. army.<ref name=":17" /> (1944, 430) His daughter Lavender was married to John Everett, and Diane was married to Elwyn Villiers Rhys. What was settled land totalled £168,975 and went to William Adam de Geijer, retired captain, H.M. army, and George Lawrence Stewart, solicitor.<ref name=":17" /> (1944, 430)

(From the ''World''.)
The marriage of "Mr. Manton" was the surprise as well the sensation of last week. Although some wise people noticed a certain amount of youthful ardour in the attentions paid by Mr. Marcus Henry Milner to Caroline Duchess of Montrose at '''Mrs. Oppenheim's ball''', nobody was prepared for the sudden ''dénouement''; '''and it''' were not for the accidental and unseen presence [[Social Victorians/People/Mildmay|a well-known musical amateur]] who had received permission to practice on the organ, the ceremony performed at half-past nine on Thursday morning at St. Andrew's, Fulham, by the Rev. Mr. Propert, would possibly have remained a secret for some time to come. Although the evergreen Duchess attains this year the limit of age prescribed the Psalmist, the bridegroom was only born in 1864. Mr. "Harry" Milner (familiarly known in the City as "Millions") was one of the zealous assistants of that well-known firm of stockbrokers, Messrs. Bourke and Sandys, and Mr. Algernon Bourke, the head of the house (who, of course, takes a fatherly interest in the match) went down to Fulham to give away the Duchess. The ceremony was followed by a ''partie carrée'' luncheon at the Bristol, and the honeymoon began with a visit to the Jockey Club box at Sandown. Mr. Milner and the Duchess of Montrose have now gone to Newmarket. The marriage causes a curious reshuffling of the cards of affinity. Mr. Milner is now the stepfather of the [[Social Victorians/People/Montrose|Duke of Montrose]], his senior by twelve years; he is also the father-in-law of [[Social Victorians/People/Lady Violet Greville|Lord Greville]], Mr. Murray of Polnaise, and [[Social Victorians/People/Breadalbane|Lord Breadalbane]].<ref name=":8" /></blockquote>

Li inspected the monument with marked interest, and drew the attention of his suite to the remarkable likeness to the dead hero. He laid a handsome wreath of royal purple asters, lilies, maidenhair fern, and laurel, tied with a broad band of purple silk, on the tomb.
The visit was not one of inspection of the building, but on passing the middle aisle the interpreter called the attention of His Excellency to the exquisite architecture and decoration of the chancel.

The greater portion of the club property had already been removed to the new premises, but Mr Algernon Bourke, his private secretary, and some of the officials of the club, still occupied bed-rooms at the house in the King’s-road. The corner shop of the street front is occupied by Mr. Marx, a jeweller in a large way of business, and upon his manager arriving at nine o'clock he discovered that the place had been entered through hole in the ceiling, and a great part of a very valuable stock of jewelry extracted. An examination of the morning rooms of the club, which runs over Mr. Marx's establishment reveal a singularly neat specimen of the burglar's art. A piece of the flooring about 15in square had been removed by a series of holes bored side by side with a centre-bit, at a spot where access to the lofty shop was rendered easy by a tall showcase which stood convemently near. A massive iron girder had been avoided by a quarter of an inch, and this circumstance and the general finish of the operation point to an artist in his profession, who had acquired an intimate knowledge of the premises. The club doors were all found locked yesterday morning, and the means of egress adopted by the thief are at present a mystery.<ref>"Burglary at Brighton."

==== Salammbô ====
Salammbô is the fictitious protagonist in Gustave Flaubert's 1862 novel ''Salammbô'', set during the Roman war against Carthage.<ref name=":5">{{Cite journal|date=2024-04-29|title=Salammbô|url=https://en.wikipedia.org/w/index.php?title=Salammb%C3%B4&oldid=1221352216|journal=Wikipedia|language=en}} https://en.wikipedia.org/wiki/Salammb%C3%B4.</ref> Salammbô is a Carthaginian priestess of the lunar goddess Tanit. Matho, a Roman mercenary, breaks into Tanit's temple and steals her sacred veil — the spiritual guardian of Carthage. Salammbô sneaks into Matho's tent in the enemy encampment to steal the veil back. She meets him there, and "believing each other to be divine apparitions," they make love.<ref name=":5" /> Salammbô succceds in getting the veil back, but the effect of both having touched it is that Matho is tortured and executed, which causes her to die of shock.
Ernest Reyer's opera ''Salammbô'' was based on Flaubert's novel and published in Paris in 1890 and performed in 1892<ref>{{Cite journal|date=2024-04-11|title=Ernest Reyer|url=https://en.wikipedia.org/w/index.php?title=Ernest_Reyer&oldid=1218353215|journal=Wikipedia|language=en}} https://en.wikipedia.org/wiki/Ernest_Reyer.</ref> (both Modest Mussorgsky and Sergei Rachmaninoff had attempted but not completed operas based on the novel as well<ref name=":5" />). Alfons Mucha's 1896 lithograph of Salammbô (above left) was published the year before the ball.[[File:Algernon Henry Bourke Vanity Fair 20 January 1898.jpg|thumb|alt=Old colored drawing of an elegant elderly man dressed in a 19th-century tuxedo with a cloak, top hat and formal pointed shoes with bows, standing facing 1/4 to his right|''Algy'' — Algernon Henry Bourke — by "Spy," ''Vanity Fair'' 20 January 1898]]

'''Lafayette's portrait''' (left) of "Hon.

This portrait is amazing and unusual: Algernon Bourke is not using a photographer's set with theatrical flats and props, certainly not one used by anyone else at the ball itself. Isaak Walton (baptised 21 September 1593 – 15 December 1683) wrote ''The Compleat Angler''.<ref>{{Cite journal|date=2021-09-15|title=Izaak Walton|url=https://en.wikipedia.org/w/index.php?title=Izaak_Walton&oldid=1044447858|journal=Wikipedia|language=en}} https://en.wikipedia.org/wiki/Izaak_Walton.</ref> A cottage Walton lived in and willed to the people of Stafford was photographed in 1888, suggesting that its relationship to Walton was known in 1897, raising a question about whether Bourke could have used the fireplace in the cottage for his portrait. (This same cottage still exists, as the [https://www.staffordbc.gov.uk/izaak-waltons-cottage Isaak Walton Cottage] museum.)
A caricature portrait (right) of the Hon. Algernon Bourke, called "Algy," by Leslie Ward ("Spy") was published in the 20 January 1898 issue of ''Vanity Fair'' as Number 702 in its "Men of the Day" series,<ref>{{Cite journal|date=2024-01-14|title=List of Vanity Fair (British magazine) caricatures (1895–1899)|url=https://en.wikipedia.org/w/index.php?title=List_of_Vanity_Fair_(British_magazine)_caricatures_(1895%E2%80%931899)&oldid=1195518024|journal=Wikipedia|language=en}} https://en.wikipedia.org/wiki/List_of_Vanity_Fair_(British_magazine)_caricatures_(1895%E2%80%931899).</ref> giving an indication of what he looked like out of costume.

== Notes and Questions ==
#The portrait of Algernon Bourke in costume as Isaac Walton is really an amazing portrait with a very interesting setting, far more specific than any of the other Lafayette portraits of these people in their costumes. Where was it shot? Lafayette is given credit, but it's not one of his usual backdrops. If this portrait was taken the night of the ball, then this fireplace was in Devonshire House; if not, then whose fireplace is it?
#The ''Times'' lists Hon. A. Bourke (at 325) and Hon. Mrs. A. Bourke (at 236) as members of a the "Oriental" procession, Mr. and Mrs. A. Bourke (in the general list of attendees), and then a small distance down Mr. and Mrs. Bourke (now at 511 and 512, respectively). This last couple with no honorifics is also mentioned in the report in the London ''Evening Standard'', which means the Hon. Mrs. A. Bourke, so the ''Times'' may have repeated the Bourkes, who otherwise are not obviously anyone recognizable. If they are not the Hon. Mr. and Mrs. A. Bourke, then they are unidentified. It seems likely that they are the same, however, as the newspapers were not perfectly consistent in naming people with their honorifics, even in a single story, especially a very long and detailed one in which people could be named more than once.
#Three slightly difficult-to-identify men were among the Suite of Men in the [[Social Victorians/1897 Fancy Dress Ball/Quadrilles Courts#"Oriental" Procession|"Oriental" procession]]: [[Social Victorians/People/Halifax|Gordon Wood]], [[Social Victorians/People/Portman|Arthur B. Portman]] and [[Social Victorians/People/Sarah Spencer-Churchill Wilson|Wilfred Wilson]]. The identification of Gordon Wood and Wilfred Wilson is high because of contemporary newspaper accounts. The Hon. Algernon Bourke, who was also in the Suite of Men, is not difficult to identify at all. Arthur Portman appears in a number of similar newspaper accounts, but none of them mentions his family of origin.

<blockquote>[[W:Branko Grünbaum|Grünbaum]] and [[W:H.S.M.

The 11-cell is described as an abstract 4-polytope, because its cells do not have a realization in Euclidean 3-space. However, we find that the 11-cell has a realization in Euclidean 4-space inscribed in the [[120-cell|120-cell]], the largest regular convex 4-polytope, which contains inscribed instances of all the convex regular 4-polytopes. The 11-cell contains 11 hemi-icosahedra and 11 regular 5-cells. The 120-cell contains 120 dodecahedra and 120 regular 5-cells. We find that the 120-cell also contains: a non-uniform icosahedral polyhedron that is the realization of the abstract hemi-icosahedron; real 11-cells made from 11 of it; and a nondescript compound of eleven real 11-cells. We also find a quasi-regular compound of the compound of eleven 11-cells and [[w:Schoute|Schoute]]'s compound of five 24-cells (the 600-cell). We describe the real 11-cell 4-polytope, which is the 11-point [[wikipedia:Roswitha_Blind|Blind]] polytope, an augmented rectified 5-cell; its compound of eleven 11-cells; the quasi-regular compound; and their relation to the regular polytopes.</blockquote>
== Introduction ==
[[W:Branko Grünbaum|Branko Grünbaum]] discovered the 11-cell around 1970,{{Sfn|Grünbaum|1976|loc=''Regularity of Graphs, Complexes and Designs''}} about a decade before [[W:H.S.M. Coxeter|H.S.M. Coxeter]] extracted hemi-icosahedral hexads from the permutations of eleven numbers, with observations on the perfection of Todd's cyclic pentads and other symmetries he had been studying.{{Sfn|Coxeter|1984|loc=''A Symmetrical Arrangement of Eleven Hemi-Icosahedra''}} Grünbaum started with the hexad, and the impetus for his discovery of the 11-cell was simply the impulse to build with them. Like a child building with blocks, he fit them together, three around each edge, until the arrangement closed up into a 3-sphere and surprise, ''eleven'' of them.
[[File:120-cell.gif|thumb|360px|The picture on the cover of the box.{{Sfn|Hise|2011|loc=File:120-cell.gif|ps=; "Created by Jason Hise with Maya and Macromedia Fireworks. A 3D projection of a 120-cell performing a [[W:SO(4)#Geometry of 4D rotations|simple rotation]]."}} The complex interior parts of the 120-cell, all its inscribed 600-cells, 24-cells, 8-cells, 16-cells, 5-cells and 11-cells, are completely invisible in this view, as none of their edges are rendered at all. The child must imagine them.]]
The 4-dimensional regular polytopes are the most wonderful set of child's building blocks. The simplest two 4-polytopes are the 5-point 4-[[W:Simplex|simplex]] (called the [[5-cell]], because it is built from 5 tetrahedra), and the 8-point 4-[[W:Orthoplex|orthoplex]] (called the [[16-cell]], because it is built from 16 tetrahedra). As building blocks they could not be more different. The 16-cell is the basic building block of everything 4-dimensional. Every other regular convex 4-polytope (''except'' the 5-cell) can be built as a compound of 16-cells, including first of all the [[w:Tesseract|16-point (8-cell) tesseract]], the 4-hypercube, which is a compound of two 16-cells in [[W:Demihypercube|exact dimensional analogy]] to the way a cube is a compound of two tetrahedra. The regular 5-cell, on the other hand, is not found within any of the other regular convex 4-polytopes, except in the largest and most complex one, the [[120-cell|120-cell]], the biggest thing you can build from this set of building blocks (the picture on the cover of the box, which is built from everything in the box). The 5-cell has a fundamental relationship to all the other 4-polytopes, but not one as simple as compounding. The 5-cell is not immediately useful to children trying to learn to build with 4-dimensional building blocks, but the 16-cell is our very starting point, and the most frequently used tool in the box.
Nevertheless, to build the 11-cell, we start with the 5-cell. The 5-cell and 11-cell are both self-reciprocal (their own duals). The 5-cell has 5 vertices that form 5 tetrahedral cells, and a total of 10 triangular faces and 10 edges. The 11-cell has 11 vertices that form 11 hemi-icosahedral cells, each with 10 triangular faces and 15 edges, and a total of 55 triangular faces and 55 edges.
== 5-cells and hemi-icosahedra in the 11-cell ==
[[File:Symmetrical_5-set_Venn_diagram.svg|thumb|The 5-point (10-face) regular 5-cell (the regular 4-simplex). Grünbaum's rotationally symmetrical 5-set Venn diagram{{Sfn|Grünbaum|1975|loc=''Rotationally symmetrical 5-set Venn diagram'', Fig 1 (e)|ps=; partitions the individual elements of the 5-cell.}} is an illustration of the 5-cell labeling each of its <math>2^5</math> elements.{{Sfn|Cmglee: Grunbaum's 5-point Venn Diagram|2019|ps=; each individual element of the 5-cell is labelled; image includes the Python code to render it, optimising for maximum area of the smallest regions.}}]]
[[File:Hemi-icosahedron.png|thumb|The 6-point (10 face) [[W:hemi-icosahedron|hemi-icosahedron]], an abstraction of the regular icosahedron, has half as many faces, edges and vertices. Each element of the abstract polyhedron represents two or more real elements found in different places in a concrete realization of the 11-cell.{{Sfn|Ruen: hemi-icosahedron|2007}}]]
The most apparent relationship between the pentad 5-cell and the hexad hemi-icosahedron is that they both have 10 triangular faces. When we find a facet congruence between a 4-polytope and a 3-polytope we suspect a dimensional analogy. In the exceptional case of 5-cell and icosahedron, which share the same symmetry group <math>A_5</math>, we fully expect a dimensional analogy.{{Efn|There is an exceptional inter-dimensional duality between the regular icosahedron and the 5-cell because they share <math>A_5</math> symmetry. See this question asked on [https://math.stackexchange.com/questions/4235783/the-rotational-symmetry-groups-of-the-5-cell-and-the-icosahedron-are-isomorphi math.stackexchange.com 2021].}} A similar clue that the hemi-icosahedron has something to do with dimensional analogy comes from its realization as the 6-point 5-simplex. Yet another real hexad is the 6-point 3-orthoplex; thus the hemi-icosahedron is related by dimensional analogy to the 4-simplex (5-cell) from above, and to the 4-orthoplex (16-cell) from below, while those two simplest 4-polytope building blocks are ''only'' related to each other indirectly by dimensional analogies, having no chord congruences in 4-space. The 11-cell's cell has only been at the party 5 minutes, and it is already inter-dimensionally ''involved'' with the two earliest arrivals, the 4-simplex (5-cell) and 4-orthoplex (16-cell), who are famously stand-offish with each other. Interesting!
The cell of the 11-cell is an abstract hexad hemi-icosahedron with 5 central planes, most handsomely illustrated by Séquin.{{Sfn|Séquin|2012|loc=A 10-Dimensional Jewel}}{{Sfn|Séquin & Lanier|2007|p=3|loc=Figure 4: (b,c) two views of the hemi-icosahedron projected into 3D space|ps=; Séquin et. al. have a lovely colored illustration of the hemi-icosahedron, subdivided into 10 triangular faces by 5 central planes of its icosahedral symmetry, revealing rings of polytopes nestled in its interior. Their illustration cannot be directly included here, because it has not been uploaded to [[W:Wikimedia Commons|Wikimedia Commons]] under an open-source copyright license, but you can view it online by clicking through this citation to their paper, which is available on the web.}}{{Sfn|Séquin & Hamlin|2007|loc=Figure 2. 57-Cell: (a) vertex figure|ps=; The 6-point [[W:Hemi-isosahedron|hemi-isosahedron]] is the vertex figure of the 11-cell's dual 4-polytope the 57-point [[W:57-cell|57-cell]].}} The 11 hemi-icosahedral cells have 10 triangle faces each, and each cell is face-bonded to the other 10 cells. The 5-cell's 5 tetrahedral cells have 10 faces and 10 edges altogether, and each cell is face-bonded to the other 4 cells.{{Efn|The 11-cell and the 5-cell are the only 4-polytopes where every cell shares a face with every other cell.|name=every cell adjacent}} If 11-cell faces are 5-cell faces, then 3 of each 5-cell's 5 vertices are a hemi-icosahedron face, and its other 2 vertices must be some 11-cell edge lying opposite the face. Coxeter determined that the 11-cell does indeed have an edge opposite each face, that does not belong to the same hemi-icosahedral cell as its opposing face. He found that the 10 edges opposite each hemi-icosahedron's 10 faces are the 10 edges of a single 5-cell, which does not share any vertices, edges or faces with the hemi-icosahedron. For each cell of the 11-point 11-cell, there is exactly one such 5-point 5-cell that is completely disjoint from the 6-point hemi-icosahedron cell.{{Sfn|Coxeter|1984|p=110|loc=§6. The Petrie polygon [of the 11-cell]|ps=; "We may reasonably call this edge and face ''opposites''. It is easy to find the face opposite to a given edge by looking at the faces to which a given edge belongs. ... Conversely, given a face, we can find the opposite edge by seeing which vertices belong to neither of the hemi-icosahedra which share that face. The ten edges opposite to the ten faces of one hemi-icosahedron are the edges of the complementary <math>a_4</math> [4-simplex], that is, the joins of all pairs of the five vertices [of the 11-cell] not belonging to the given hemi-icosahedron."}}
There are 11 disjoint 5-cell 4-polytopes inscribed in each 11-cell, which also contains 11 hemi-icosahedral cells, 55 faces, 55 edges and 11 vertices. The real 11-cell is more complex than the abstract 11-cell representing it, because the real hemi-icosahedron is more complex and harder to see than the abstract hemi-icosahedron. Seeing the real 11-cell will be easier once we have identified the real hemi-icosahedron, and seen exactly where the 11-cell's real elements reside in the other 4-polytopes within the 120-cell with which the 11-cell intermingles.
The 5-cell has 10 faces, and the 11-cell has 10 faces in each of its hemi-icosahedral cells, but that is not how their faces correspond. Each hemi-icosahedron is face-bonded to the other 10 hemi-icosahedra, and to 10 of the 11 5-cells, and there is exactly one 5-cell with which it does not share a face.{{Efn|As Coxeter observes (in the previous citation), that unrepresented 5-point 5-cell is the other 5 vertices of the 11-point 11-cell that are not vertices of this 6-point hemi-icosahedron: the hemi-icosahedron's disjoint complement.}} Each 5-cell has 10 faces which belong to 10 distinct hemi-icosahedra of the 11-cell, and there is just one hemi-icosahedron with which it does not share a face.
In the abstract 11-cell each face represents two conflated icosahedron faces, two actual faces in different places, so the 11-cell's 55 faces represent 110 actual faces: the faces of 11 completely disjoint 5-cells. Each hemi-icosahedron vertex represents conflated icosahedral vertices: multiple actual vertices separated by a small distance which has been reduced to a point at the coarse scale of the abstraction.{{Efn|We shall see that this small eliminated distance is in fact the length of a 120-cell edge, the shortest chordal distance found in the 120-cell.}} Seemingly adjacent hemi-icosahedron faces do not actually meet at an edge; there is a polygon separating them, which has been abstracted to an edge. The 10 hemi-icosahedron faces are 5-cell faces from 10 distinct 5-cells, and they do not actually touch each other: the 120 5-cells in the 120-cell are completely disjoint.
In the 5-cell each face bonds two tetrahedral cells together, and in the 11-cell each face bonds two pairs of tetrahedral cells together, because each 11-cell face represents two actual 5-cell faces in two different planes. Each duplex 11-cell face bonds tetrahedra in two 5-cells in different places, without binding the 5-cells together (they are completely disjoint). One actual 5-cell face is one half of a duplex 11-cell face, so 110 5-cell faces are 55 duplex 11-cell faces. The 11-cell's 11 abstract vertices represent all 55 distinct vertices of the 11 disjoint 5-cells, so they must be abstract conflations of at least 5 vertices. Therefore for any of this to be possible, the 11-cell must not be alone; 11-cells must be sharing vertices, not disjoint as the 5-cells are.

We shall see in subsequent sections that the 11-cell is not in fact alone, but first let us see if we can find an existing illustration of the realization of the abstract hemi-icosahedron, as an actual polyhedron that occurs in the 120-cell. Moxness developed software which uses Hamilton's [[w:Quaternion|quaternion]]s to render the polyhedra which are found in the interior of ''n''-dimensional polytopes.{{Sfn|Moxness: Quaternion graphics software|2023|ps= ; describes the theory and implementation of quaternion-based polytope graphics software.}} [[w:William_Rowan_Hamilton|Hamilton]] was the first wise child to discover a 4-dimensional building block, [[w:History_of_quaternions#Hamilton's_discovery|in his flash of genius on Broom bridge]] in 1843, though he didn't think of his quaternion formula {{math|1=''i''<sup>2</sup> = ''j''<sup>2</sup> = ''k''<sup>2</sup> = ''ijk'' = −1}} as the [[W:Tesseract|16-point (8-cell) tesseract]] 4-polytope. He did not realize then that he had discovered the 4-hypercube polytope and [[W:Tesseractic honeycomb|its honeycomb]], the tetrad (w, x, y, z) Cartesian [[w:Euclidean_geometry#19th_century|coordinates of Euclidean 4-space]]. Moxness built his software out of Hamilton's quaternions, as quite a lot of graphics software is built, because quaternions make rotations and projections in 3D or 4D space as simple as matrix multiplications. The quaternions are 4-hypercube building blocks, analogous to the 3-hypercube wooden blocks everyone built with as a child (only they fit together even better, because they are [[w:8-cell#Radial_equilateral_symmetry|radially equilateral]] like the cuboctahedron and the [[24-cell]], but we digress). Moxness used his software to render illustrations of the polyhedra inside the 120-cell, which he published. Notice his "Hull # = 8 with 60 vertices", lower right. It is a real icosahedron that the abstract hemi-icosahedron represents, as it occurs in the 120-cell. Moxness's 60-point (Hull #8) is a concrete realization of the 6-point hemi-icosahedron in spherical 3-space <math>S^3</math>, embedded in Euclidean 4-space <math>R^4</math>. Its 12 little pentagon faces are 120-cell faces. It also has 20 triangle faces like any icosahedron, separated from each other by rectangles, but beware: those triangles are not the 5-cell faces.

Edges of the larger 5-cell face triangles of edge length <math>\sqrt{5}</math> can also be found in Hull #8, but they are invisible chords below the surface of Moxness's 60-point polyhedron. To see them, notice that six 120-cell edges (little pentagon edges) lie on a great circle, alternating with six rectangle diagonals. Also lying on this irregular {12} great circle are six 5-cell edges, invisible chords joining every other 120-cell edge and running under the 120-cell edge between them. The six long chords and six short edges form two opposing irregular {6} great hexagons (truncated triangles) of alternating 5-cell edges and 120-cell edges, as illustrated. The irregular {12} great dodecagon lies on a great circle of Moxness's 60-point polyhedron, and also on a great circle of the 120-cell, because Moxness's Hull #8 is the ''central'' cell-first section of the 120-cell.{{Efn|The cell-first central section of the 600-cell (and of the 24-cell) is a cuboctahedron with 24-cell edges.

Their 24-cell edges, like the 5-cell edges, are invisible chords of Hull #8 that lie below its surface, on the same irregular {12} great circles. Each 24-cell edge chord spans one 120-cell edge chord (one little pentagon edge) and one rectangle face diagonal chord.

Moxness's 60-point (Hull #8) is a nonuniform form of an Archimedean solid, the 60-point [[W:Rhombicosidodecahedron|rhombicosidodecahedron]] from [[W:Johannes Kepler|Kepler's]] 1619 [[W:Harmonices Mundi|''Harmonices Mundi'']], which has the same 120 edges, 20 triangular faces and 12 pentagon faces, but with 30 squares between them instead of 30 rectangles. Without the squares ''or'' the rectangles it would be the 30-point [[W:icosidodecahedron|icosidodecahedron]], which has the same relationship to Moxness's 60-point (Hull #8) that the 6-point hemi-icosahedron does: they are both abstractions of it by conflation of its 60 points, 2-into-1 (icosidodecahedron) and 10-into-1 (hemi-icosahedron), in what [[w:Alicia_Boole_Stott|Alicia Boole Stott]] named a ''contraction'' operation.{{Efn|The regular 5-point 5-cell can be another abstraction of Moxness's 60-point (Hull #8), 12-vertices-into-1. None of these contractions of Moxness's 60-point is an instance of her operation actually described by Boole Stott, since she did not apply her expansion and contraction operations to uniform polytopes with more than one edge length, but she did explicitly describe contractions of the semi-regular Archimedean rhomibicosidodecahedron.}} In fact Moxness was not the first person to find rhombicosidodecahedra in the 120-cell. Alicia Boole Stott identified the 6th section of {5,3,3} beginning with a cell as the semi-regular rhombicosidodecahedron that is her ''e<sub>2</sub> expansion'' of the icosahedron (or equivalently of its dual polyhedron the dodecahedron).{{Sfn|Boole Stott|1910|loc=§Examples of the e<sub>2</sub> expansion|p=7}} But that 6th section rhombicosidodecahedron identified by Boole Stott is not Moxness's Hull #8, it is the semi-regular Archimedean solid (Moxness's Hull #6), with a single edge length and square faces. Moxness's Hull #8, with its two distinct edge lengths and rectangular faces, is Coxeter's 8<sub>3</sub>, the 8th section of {5,3,3} beginning with a cell, which is missing from the sections illustrated by Boole Stott.{{Sfn|Coxeter|1973|p=258-259|loc=§13.9 Sections and Projections: Historical remarks|ps=; "Alicia Boole Stott (1860-1940) ... also constructed the sections i<sub>3</sub> of {5, 3, 3}, exhibiting the nets in her Plate V. “Diagrams VIII-XIV” refer to the sections 1<sub>3</sub>-7<sub>3</sub>; but 8<sub>3</sub> is missing. Incidentally, Diagram XIII (our 6<sub>3</sub>) is a rhombicosidodecahedron, the Archimedean solid."}} Coxeter found section 8<sub>3</sub> first, and gave its coordinates, but he did not identify it as an irregular rhombicosidodecahedron; his table entry for its description as a polyhedron is empty, suggesting that he never visualized it. Although Moxness was not the first to compute the 60-point 8<sub>3</sub> section, he was apparently the first person to ''see'' it.
The 30-point icosidodecahedron is the quasi-regular product of 5-point pentagon and 6-point hexagon, recalling Coxeter's original discovery of the 11-cell in pentads and hexads, and also the two child's building blocks: one so useless the 5-point (pentad) 5-cell, and the other so useful the 8-point 16-cell with its four orthogonal 6-point (hexad) octahedron central sections, which can be compounded into everything larger. Some children building with the 30-point icosidodecahedron notice that it occurs as the central section 4<sub>0</sub> of the 120-point 600-cell. It is less often noticed that Moxness's 60-point rhombicosidodecahedron is the central section 8<sub>3</sub> of the 600-point 120-cell. It occupies a flat 3-dimensional hyperplane that bisects the 120-cell, and since there are 120 dodecahedral cells, there are 60 such central hyperplanes, each perpendicular to an axis that connects the centers of two antipodal cells.
The 60 central hyperplanes, each containing an instance of Moxness's 60-point (Hull #8), are rotated with respect to each other.{{Efn|Each of the 120 dodecahedral cells lies in the closed, curved 3-dimensional space of the 3-sphere as the center of a series of concentric hulls of increasing size, nested like Russian dolls. Moxness's 60-point (section 8<sub>3</sub>) is the 8th, largest-radius concentric hull, a central section of the 120-cell that bisects the 3-sphere the way an equator bisects an ordinary sphere. Such a central polyhedron is the 4-dimensional analog of an equatorial great circle polygon. Its 60 vertices lie in the same 3-dimensional hyperplane, a flat 3-dimensional section sliced through the 120-cell. There are 60 distinct stacks of such parallel hyperplanes in the 120-cell, one stack spindled on each cell-center-to-antipodal-cell-center axis, with a dodecahedral cell (a section 1<sub>3</sub>) at each end of the stack. The largest-radius 60-point (section 8<sub>3</sub>) central slice lies in the center of the stack, and the smaller non-central section hyperplanes occur in parallel pairs on either side of the central slice. The 120-cell therefore contains 120 instances of each kind of non-central section 1<sub>3</sub> through 7<sub>3</sub>, and 60 instances of the central section 8<sub>3</sub>.|name=polyhedral sections beginning with a cell}} They intersect each other, with 6 rhombicosidodecahedra sharing each vertex and 3 sharing each edge, but each little pentagon face (120-cell face) belongs to just one rhombicosidodecahedron. The 60 central sections lie in distinct isoclinic hyperplanes, that is, the rhombicosidodecahedra are rotated in 4-space symmetrically with respect to each other, by two equal angles.{{Sfn|Kim|Rote|2016|p=7|loc=§6 Angles between two Planes in 4-Space|ps=; "In four (and higher) dimensions, we need two angles to fix the relative position between two planes. (More generally, ''k'' angles are defined between ''k''-dimensional subspaces.)"}} Each pair of rhombicosidodecahedra intersect only in a single central plane containing an irregular {12} dodecagon, and share its 12 vertices. But because the 5-cell faces do not lie in central planes, each 5-cell face occurs in only one rhombicosidodecahedron, just as it occurs in only one 5-cell. The 60 rhombicosidodecahedra meet 6 at each vertex, 2 at each {12} central plane, 3 at each 5-cell edge, 3 at each 120-cell edge, and 2 at each rhombicosidodecahedron face.
We have come far enough with our pentad building blocks, usually so useless to children less wise than Todd or Coxeter, to see that the 60 Moxness's 60-point (Hull #8) rhombicosidodecahedra are real polyhedra which the abstract hemi-icosahedra represent, but we have not yet identified 11 real hemi-icosahedral face-bonded cells, at 11 distinct locations in the 120-cell, as an 11-cell. The abstract hemi-icosahedron's 10 faces represent actual 5-cell faces inscribed in real rhombicosidodecahedra, and its 15 edges represent 5-cell edges (of length {{radic|5}} in a {{radic|2}}-radius 120-cell) that occur as chords lurking under the surface of the rhombicosidodecahedra. Each 5-cell edge is shared by three rhombicosidodecahedra, but each 5-cell face is contained within just one rhombicosidodecahedron.

At this point, we should orient ourselves by recalling that the centers of the 12 little pentagon faces of Moxness's rhombicosidodecahedron are the vertices of the regular icosahedron, which frames ''all'' the regular polyhedra by expansion and contraction operations. Alicia Boole Stott discovered that before 1910,{{Sfn|Polo-Blanco: ''Theory and history of geometric models of Alicia Boole Stott''|2007|loc=§5.3.2 1910 paper on semi-regular polytopes|pp=152-158|ps=; summarizes Boole Stott's method and results from {{Sfn|Boole Stott|1910|loc=''Geometrical deduction of semiregular from regular polytopes and space fillings''|pp=12-45|ps=; presents two cyclical sequences of regular and semi-regular 4-polytopes linked by expansion-contraction operations to their embedded 3-polytopes, comprising a large trans-dimensional polytope family that includes 6 regular 4-polytopes and their 3-polytope dimensional analogues, and 45 Archimedean 4-polytopes and their 13 Archimedean 3-polytope analogues.}}, including her tables of expansion-contraction dimensional analogies and a few of her illustrations.}} and those wise young friends Coxeter & Petrie, building together with polyhedral blocks, rediscovered it before 1938.{{Sfn|Coxeter|du Val|Flather|Petrie|1938|p=4|ps=; "Just as a tetrahedron can be inscribed in a cube, so a cube can be inscribed in a dodecahedron. By reciprocation, this leads to an octahedron circumscribed about an icosahedron. In fact, each of the twelve vertices of the icosahedron divides an edge of the octahedron according to the "[[W:Golden section|golden section]]". Given the icosahedron, the circumscribed octahedron can be chosen in five ways, giving a [[W:Compound of five octahedra|compound of five octahedra]], which comes under our definition of [[W:Stellated icosahedron|stellated icosahedron]]. (The reciprocal compound, of five cubes whose vertices belong to a dodecahedron, is a stellated [[W:Triacontahedron|triacontahedron]].) Another stellated icosahedron can at once be deduced, by stellating each octahedron into a [[W:Stella octangula|stella octangula]], thus forming a [[W:Compound of ten tetrahedra|compound of ten tetrahedra]]. Further, we can choose one tetrahedron from each stella octangula, so as to derive a [[W:Compound of five tetrahedra|compound of five tetrahedra]], which still has all the rotation symmetry of the icosahedron (i.e. the icosahedral group), although it has lost the reflections. By reflecting this figure in any plane of symmetry of the icosahedron, we obtain the complementary set of five tetrahedra. These two sets of five tetrahedra are enantiomorphous, i.e. not directly congruent, but related like a pair of shoes. [Such] a figure which possesses no plane of symmetry (so that it is enantiomorphous to its mirror-image) is said to be ''[[W:Chiral|chiral]]''."}} Before we move on to locating the 11 discrete hemi-icosahedron cells of the 11-cell in the 120-cell, it is important to notice one more icosahedral symmetry of the hidden {{radic|5}} chords lurking below the surface of Moxness's 60-point rhombicosidodecahedron. The 12 little pentagon faces (120-cell faces) are connected to each other in opposing pairs, by 10 sets of six {{radic|5}} chords (5-cell edges). The six chords of each set are disjoint (they don't touch or form 5-cell faces), and they are symmetrically arranged as 3 parallel pairs, {{radic|3}} apart, which lie in 3 orthogonal central planes. Each 120-cell pentagon face lies at one end of ten chords from five disjoint 5-cells: two at each vertex from the same 5-cell, but from two distinct sets of six disjoint chords. It turns out each six-chord set is the six reflex edges of a 12-point non-convex polyhedron called the [[w:Jessen's_icosahedron|Jessen's icosahedron]]. The six disjoint chords are the parallel-orthogonal strut chords of a [[WikiJournal Preprints/Kinematics of the cuboctahedron#Elastic-edge transformation|tensegrity icosahedron]].

== The eleventh chord ==
Each pair of rhombicosidodecahedra intersects only in a single central plane containing an irregular {12} dodecagon. 10 irregular great {12} dodecagons occur in each 60-point (section 8<sub>3</sub>) rhombicosidodecahedron, with 2 dodecagons crossing at each vertex. Each rhombicosidodecahedron shares a {12} central plane with 10 distinct other rhombicosidodecahedra. Groups of 11 rhombicosidodecahedra share central planes pairwise.
Here, at last, we find eleven of something. That group of 11 rhombicosidodecahedra sharing central planes pairwise must comprise an 11-cell. All we have seen them sharing is a single {12} central plane between each pair of rhombicosidodecahedra, much as any 4-polytope's cells share only a single face plane between each pair of adjacent cells.{{Efn|name=every cell adjacent}} But a central plane is not ordinarily a face plane, and the rhombicosidodecahedra do not share the 5-cell faces they contain in their interior.
Each shared {12} central plane contains 6 disjoint 5-cell edges (from 6 different 5-cells), and each rhombicosidodecahedron contains 20 disjoint 5-cell faces (which do ''not'' lie in its ten {12} central planes). Each {12} central plane occurs in 2 rhombicosidodecahedra which meet there. Each rhombicosidodecahedron contains 60 5-cell edges, which form 20 completely disjoint 5-cell faces within the rhombicosidodecahedron. Four 5-cell edges meet at each vertex at the 5-cell's tetrahedral vertex figure. Two 5-cell edges of a face within the rhombicosidodecahedron meet two edges belonging to other faces of the 5-cell: edges and faces which lie within other rhombicosidodecahedra. Adjacent rhombicosidodecahedra share only 5-cell edges, not 5-cell faces: three rhombicosidodecahedra meet around each 5-cell edge. Each 5-cell face is shared by two tetrahedral cells of a 5-cell, but not by two rhombicosidodecahedra: it lies within just one rhombicosidodecahedron. There is no 5-cell face sharing between rhombicosidodecahedra, although each rhombicosidodecahedron shares each of its {12} central planes pairwise with one other rhombicosidodecahedron. Each 5-cell face has its 3 edges in 3 distinct {12} central planes.
[[File:Regular_star_figure_2(15,4).svg|thumb|The [[W:Triacontagon#Triacontagram|{30/8}{{=}}2{15/4} triacontagram]] of the 5-cell rotation.]]There is no face sharing between 5-cells either: the 120 5-cells in the 120-cell are completely disjoint. 5-cells never share any elements, but they are related to each other positionally, in groups of six, by an isoclinic rotation characteristic of the 5-cell: the rotation over the 5-cell's edges.{{Efn|The Petrie polygon of the 120-cell is a skew {30} triacontagon. There are 30 and only 30 distinct chordal distances between vertices in the 120-cell. The 120-cell's edge is the {30/1} chord. The 5-cell edge chord is the {30/8} chord, because it connects two vertices which are 8 120-cell edges apart on the 120-cell's 30-edge Petrie polygon.}} That rotation takes the six 5-cells within each group to each other's positions, and back to their original positions, in a circuit of 15 rotational displacements.{{Sfn|Mamone|Pileio|Levitt|2010|loc=§4.5 Regular Convex 4-Polytopes, Table 2, Symmetry operations|pp=1438-1439|ps=; in symmetry group 𝛢<sub>4</sub> the operation [15]𝑹<sub>q3,q3</sub> is the 15 distinct rotational displacements which comprise the class of pentadecagram isoclinic rotations of the 5-cell in the invariant planes of its edges; in symmetry group 𝛨<sub>4</sub> the operation [1200]𝑹<sub>q3,q13</sub> is the 1200 distinct rotational displacements which comprise the class of pentadecagram isoclinic rotations of the 120-cell in the invariant planes of its edges.}} The 5 vertices of each 5-cell rotate in parallel, on non-intersecting 15-chord circular isocline paths, from 5-cell to 5-cell, before closing their circuits and returning the moving 5-cell to its original location and orientation. Each vertex moves on a curved isocline, over a skew polygon of 15 chords, that is one disjoint half of a {30/8}=2{15/4} compound polygram, in which a {30/8} chord connects every eighth vertex of the {30} triacontagram.{{Efn|We shall have more to say about this rotation later, but please note that the 4-space chordal distance of each rotational displacement, as measured in the stationary reference frame, is not actually a 5-cell edge {30/8} chord of length {{radic|5}}, but a longer {30/10} chord of length {{radic|6}}. The 2-dimensional {30/8}{{=}}2{15/4} compound polygram lies skew in 4-space; it is a circular double helix of two 15-gon helical isoclines, winding through 4 dimensions.

In 4-space those 15 chords are actually {30/10} chords of length {{radic|6}}. Projected to a 2-dimensional perspective view, they are foreshortened into {30/8} chords.}}
[[File:Major chord 11 of 135.5° in the 120-cell.png|thumb|The 120-cell contains 200 irregular {12} central planes containing 1200 135.5° {30/11} chords, six in each plane (shown in blue).

[[File:Regular_star_polygon_30-11.svg|thumb|The [[W:Triacontagon#Triacontagram|{30/11} triacontagram]] of the 11-cell rotation.]]The same {12} central planes also contain six {30/11} chords of length <math>\phi^2</math>, parallel to the six {30/8} chords of length {{radic|5}}. The {30/11} chords are one 120-cell edge longer than the {30/8} chords. They do not form triangles within the rhombicosidodecahedron like the {30/8} chords, but they do meet at a tetrahedral vertex figure. Groups of 11 rhombicosidodecahedra (an 11-cell) share central planes pairwise, including the chords in the central plane. When 11 things, all pairwise-adjacent to each other, are arranged in any circuit of 30 positions, there exists another circuit of 30 positions through every eleventh position, whether the things are 11 vertices, 11 rhombicosidodecahedra, or 11 [[w:Aardvark|aardvarks]] (though it might be impractical to so arrange 11 arrdvarks, e.g. by tying them together pairwise with cords). This is simply a property of the [[w:Rational_number|rational number]] 30/11. Therefore the 11 rhombicosidodecahedra of the 11-cell are linked by a regular {30/11} triacontagram of 30 chords which runs through them. Each successive chord of the 30 in the triacontagram is shared by a distinct pair of rhombicosidodecahedra in the 11-cell group. An isoclinic rotation characteristic of the 11-cell takes the rhombicosidodecahedra in each 11-cell to each other's positions, pair by pair, in a circuit of 30 rotational displacements. The 60 vertices of each rhombicosidodecahedron rotate in parallel, on non-intersecting 30-chord circular paths, from rhombicosidodecahedron to rhombicosidodecahedron, before closing their circuits and returning the moving rhombicosidodecahedron to its original location and orientation. In this isoclinic rotation of a rigid 120-cell, the 60 rhombicosidodecahedra do this concurrently. Each of the 600 vertices moves on a curved isocline, over a skew polygon of 30 {30/11} chords, that is a regular {30/11} polygram, in which a {30/11} chord connects every eleventh vertex of the {30} triacontagram.{{Efn|We shall have more to say about this rotation later, but please note that the 4-space chordal distance of each rotational displacement, as measured in the stationary reference frame, ''is'' a {30/11} chord of length <math>\phi^2</math>. However, the 5-cell edges are not the real 11-cell's rotation plane edges. The actual 11-cell rotation edge chord is ''not'' the 5-cell edge {30/8} chord of length {{radic|5}}, but the longer {30/10) chord of length {{radic|6}}.}}
Consider the incidence of these 30-chord {30/11} triacontagram rotation paths, and their intersections. Each rhombicosidodecahedron has 60 vertices and 60 {30/11} chords, which rotate concurrently on parallel 30-position paths. The 120-cell has only 600 vertices and 1200 {30/11} chords, so the 30-position paths of the 60 vertices circling in parallel cannot be disjoint; they must intersect. But the 11 vertices of an 11-cell must be linked by disjoint 30-position {30/11} triacontagram helices, so their rotation paths never intersect.{{Efn|The isoclines on which a 4-polytope's vertices rotate in parallel never intersect. Isoclinic rotation is a concurrent motion of Clifford parallel (disjoint) objects over non-intersecting (disjoint) circles.}} The 120-cell has 121 distinct {30/11} triacontagram helices, which are 11 disjoint {30/11} triacontagram helices in 11 distinct ways.{{Efn|...}}
In the course of a complete isoclinic revolution (30 rotational displacements), an 11-cell visits the positions of 10 other 11-cells (in several orientations) and returns to its original position and orientation. At each step it occupies the same distinct group of 11 rhombicosidodecahedra sharing {12} central planes pairwise. A group of 4-polytopes related by an isoclinic rotation is a larger 4-polytope which subsumes them. This group of eleven 11-cells related by an isoclinic rotation is not a compound of eleven disjoint 11-cells (since they share vertices), but it is a compound of eleven non-disjoint 11-cells, in the same sense that a 24-cell is a compound of three non-disjoint 8-cell tesseracts.

[[120-cell#Geometry|The 120-cell is the maximally complex regular 4-polytope]], containing inscribed instances of every kind of regular 1-, 2-, 3-, and 4-polytope, up to the heptagon {7}. The 120-cell is the convex hull of a regular [[120-cell#Relationships among interior polytopes|compound of each of the other 5 regular convex 4-polytopes]].
{{Regular convex 4-polytopes|columns=7|wiki=W:|radius={{radic|2}}}}
=== How many building blocks, how many ways ===
The 120-cell is the convex hull of a compound of 75 disjoint 16-cells, of 25 disjoint 24-cells, of 5 disjoint 600-cells, and of 120 disjoint regular 5-cells. Children building the 120-cell up from their 16-cell building blocks will soon learn to protect their sanity by thinking of these nesting 4-polytopes by their alternate names, as ''n''-points symmetrically distributed on the 3-sphere, as synonyms for their conventional names, as ''n''-cells tiling the 3-sphere. They are the 8-point (16-cell), the 16-point (8-cell) tesseract, the 24-point (24-cell), the 120-point (600-cell), and the 600-point (120-cell).
The 8-point (16-cell), not the 5-point (5-cell), is the smallest building block, which compounds to everything else. The 8-point compounds by 2 in the 16-point, and by 3 in the 24-point; what could be simpler? The 16-point compounds in the 24-point by 3 ''non-disjoint instances'' of itself which share pairs of vertices. (We can think of non-disjoint instances as overlapping instances, except that disjoint instances overlap in space too, they just don't have overlapping vertex sets.) The 24-point compounds by 5 disjoint instances of itself in the 120-point, and the 120-point compounds by 5 disjoint instances of itself in the 600-point. So far, our child is happily building, and his castle makes sense to him. Then things get hairy.
The 24-point also compounds by <math>5^2</math> non-disjoint instances in the 120-point; it compounds into 5 disjoint instances of itself, 10 (not 5) different ways. Whichever way the child builds it, the resulting 120-point, magically, contains 25 distinct 24-points, not just 5 (or 10). This means that 15 disjoint 8-point building blocks will construct a 120-point, which then magically contains 75 distinct 8-points.
The 600-point is 5 disjoint 120-points, just 2 different ways (not 5 or 10 ways). So it is 10 non-disjoint 120-points. This means the 8-point building block compounds by 3 times <math>5^2</math> (75) disjoint instances of itself into the 600-point, which then magically contains <math>3^2</math> times <math>5^2</math> (225) distinct instances of the 24-point, and <math>3^3</math> times <math>5^2</math> (675) distinct instances of the original 8-point.
They will be rare wise children who figure all this out for themselves, and even wiser who can see ''why'' it is so. [[W:Pieter Hendrik Schoute|Schoute]] was the first to see that the 120-point (600-cell) is a compound of 5 24-point (24-cells) ''10 different ways'', and after he saw it a hundred years lapsed until Denney, Hooker, Johnson, Robinson, Butler & Claiborne proved his result, and showed why.{{Sfn|Denney, Hooker, Johnson, Robinson, Butler & Claiborne|2020|loc=''The geometry of H4 polytopes''|ps=; This hexad of scholars from New Orleans, Louisiana extracted the truth from the permutations of the 120-point 600-cell as perspicaciously as Coxeter did from the permutations of the 11-point 11-cell.}}
So much for the compounds of 16-cells. The 120-cell is also the compound of 120 disjoint regular 5-cells. This can be seen to be equivalent to the compound of 5 disjoint 600-cells, as follows. Beginning with a single 120-point (600-cell), expand each vertex into a regular 5-cell. For each of the 120 vertices, add 4 new equidistant vertices, such that the 5 vertices form a regular 5-cell inscribed in the 3-sphere. The 120 5-cells are disjoint, and the 600 vertices form 5 disjoint 120-point (600-cells): a 120-cell.
=== Building the building blocks themselves ===
We have built every regular 4-polytope except the 5-cell out of 16-cells, but we haven't made the 16-cell (or the 5-cell) out of anything. So far, we have just accepted them both a priori, like [[W:Euclid's postulates|Euclid's postulates]], and proceeded to build with them. But it turns out that while they are the two atomic ''regular'' 4-polytopes, they are not indivisible, and can be built up as honeycombs of identical smaller ''irregular'' 4-polytopes. They are not a priori miracles; like everything else fundamental in nature, including Euclid's postulates, at root they are an expression of a distinct [[w:Symmetry_group|symmetry group]].
Every regular convex ''n''-polytope can be subdivided into instances of its characteristic ''n''-[[W:Orthoscheme|orthoscheme]] that meet at its center. An ''n''-orthoscheme (not an ''n''-[[w:Orthoplex|orthoplex]]!) is an ''irregular'' ''n''-[[w:Simplex_(geometry)|simplex]] with faces that are various right triangles instead of congruent equilateral triangles. A characteristic ''n''-orthoscheme possesses the complete symmetry of its ''n''-polytope without any redundancy, because it contains one of each of the polytope's characteristic root elements. It is the gene for the polytope, which can be replicated to construct the polytope.{{Efn|A [[W:Schläfli orthoscheme|Schläfli orthoscheme]] is a [[W:Chiral|chiral]] irregular [[W:Simplex|simplex]] with [[W:Right triangle|right triangle]] faces that is characteristic of some polytope if it will exactly fill that polytope with the reflections of itself in its own [[W:facet (geometry)|facet]]s (its ''mirror walls''). Every regular polytope can be partitioned radially by its planes of symmetry (Coxeter's "reflecting circles") into instances of its [[W:Orthoscheme#Characteristic simplex of the general regular polytope|characteristic orthoscheme]] surrounding its center. The characteristic orthoscheme and its chiral mirror image can be replicated rotationally to generate its regular 4-polytope because it is the complete [[W:gene|gene]] for it, containing all of its elements and capturing all of its symmetry without any redundancy. It has the shape described by the same [[W:Coxeter-Dynkin diagram|Coxeter-Dynkin diagram]] as the regular polytope without the ''generating point'' ring that triggers the reflections.|name=Characteristic orthoscheme}}
The regular 4-simplex (5-cell) is subdivided into 120 instances of its [[5-cell#Orthoschemes|characteristic 4-orthoscheme]] (an irregular 5-cell) by all of its <math>A_4</math> planes of symmetry at once intersecting at its center, so its symmetry is of order 120. The 120-cell is the convex hull of the regular compound of 120 disjoint regular 5-cells, so it can be subdivided into <small><math>120\times 120 = 14400</math></small> of these 4-orthoschemes, so that is the symmetry order of the 120-cell. The 5-cell is both 1∕120th of the 120-cell, and 120 ∕120ths of itself.
The regular 4-orthoplex (16-cell) is subdivided into 384 instances of its [[16-cell#Tetrahedral constructions|characteristic 4-orthoscheme]] (another irregular 5-cell) by all of its <math>B_4</math> planes of symmetry at once intersecting at its center, so its symmetry is of order 384. The 120-cell is the convex hull of the regular compound of 75 disjoint 16-cells (which have 2-fold reflective symmetry), so its symmetry is of order <small><math>75\times 384 / 2 = 14400</math></small>.
The regular 24-point (24-cell) is subdivided into 1152 instances of its [[24-cell#Characteristic orthoscheme|characteristic 4-orthoscheme]] (yet another irregular 5-cell) by all of its <math>F_4</math> planes of symmetry at once intersecting at its center, so its symmetry is of order 1152. The 120-cell is the convex hull of the regular compound of 25 disjoint 24-cells (which have 2-fold reflective symmetry), so its symmetry is of order <small><math>25\times 1152 / 2 = 14400</math></small>.
The regular 120-point (600-cell) is subdivided into 14400 instances of its [[600-cell#Characteristic orthoscheme|characteristic 4-orthoscheme]] (yet another irregular 5-cell) by all of its <math>H_4</math> planes of symmetry at once intersecting at its center, so its symmetry is of order 14400. The regular 600-point (120-cell) is the convex hull of the regular compound of 5 disjoint 600-cells (which have 5-fold reflective symmetry), so its symmetry is of order <small><math>5 \times 14400 / 5 = 14400</math></small>.
== Concentric 120-cells ==
The 8-point 16-cell, not the 5-point 5-cell, is the smallest regular 4-polytope atomic building block, which compounds to every larger regular 4-polytope. The 5-point 5-cell is properly viewed as the ''largest'' atomic building block hierarchically, not the smallest, since it compounds to nothing else regular except the leviathan 120-cell polytope: the picture on the cover of the box, that is built from everything in the box. In the sequence of 4-polytope compounds, we start with the 16-cell at the small end, and the 5-cell emerges only at the large end.
To build with the 16-cell blocks, we simply put them on top of each other as interpenetrating compounds. We can build every other regular 4-polytope from them by that method, except the 5-cell. We can also try to build with the 5-cell that way, as when we tried to build a 4-polytope of 11 hemi-icosahedral cells from 11 5-cells, but it was hard going. We found 5-cell edges and faces lurking inside hemi-icosahedral rhombicosidodecahedra, but we didn't get all the way to a whole 11-cell made from 11 5-cells.
That's because ''compounding'' isn't the easiest method for building with the 5-cell. The 5-cell is the largest building block hierarchically, not the smallest, and the most natural way to build with it is in reverse, by ''subdividing'' it, to find what's inscribed inside it. When we've taken the 5-cell apart, all the ways we possibly can, into certain ''irregular'' 4-polytopes found within it, we will have a new set of irregular 4-polytope building blocks, which compound to the 5-cells and everything else, including the 11-cells.
Subdividing a polytope is done by a geometric operation called ''[[w:Truncation_(geometry)|truncation]]''. There are myriad ways to truncate a 5-cell, each corresponding to a distinct ''depth'' of truncation at a particular point on an edge, or a line on a face, or a face on a cell, where a piece of the 5-cell is cut off. The simplest truncations, such as [[w:Rectification_(geometry)|cutting off a vertex at the midedge of each incident edge]], have been very well-studied; but how should we proceed? Well, what happens when we [[w:Truncated_5-cell|truncate the 5-cells]] found in the 120-cell, by the simplest kinds of truncation?
If we cut off the 120-cell's 600 vertices, at some point on its 1200 5-cell edges, we create new vertices on the edges of the 120 5-cells, which lie on a smaller 3-sphere than the 120-cell. How many vertices does the smaller 4-polytope thus created have? That is, how many distinct 5-cell edge truncation points occur in the 120-cell? As many as 1200, the number of 5-cell edges, or perhaps 2400, if each edge is truncated at both ends. But also perhaps fewer; for example, if the 120-cell contains pairs of 5-cells with intersecting edges, and the edges intersect at the point on each edge where we make our cut.

The {6} intersection points (black) of the {{radic|5}} chords form a smaller regular hexagon of radius {{radic|1}} (inscribed in the red circle).]]In the irregular {12} central plane chord diagram, we see six truncation points on the six 104.5° 5-cell edges, where two co-planar 5-cell edges intersect, directly under the midpoint of a 44.5° chord. The six truncation points lie on a red circle that is the circumference of the smaller 4-polytope created by this truncation. They form a red regular hexagon inscribed in the red circle.
Each 104.5° 5-cell edge chord of length {{Radic|5}} has ''two'' points of intersection with other 5-cell edges, exactly 60° apart, the ''arc'' of a 24-cell edge chord, but with ''length'' {{radic|1}}.{{Efn|In the 120-cell, each 5-cell edge is divided into three segments, by its two intersection points with the edges of other 5-cells. The center segment is equal in length to the 120-cell's 41.4° chord, of length 1 in a {{radic|2}}-radius 120-cell. The center segment occupies 60° of arc on the circle which intersects its endpoints, the circumference of a smaller concentric 120-cell of unit radius, so it is a 60° {30/5} chord of that smaller 120-cell. The left and right segments are each equal in length to the 25.2° {30/2} chord of length 1/𝜙 (of the larger {{radic|2}}-radius 120-cell). The lengths of the left, center and right segments sum to the {30/8} chord of length {{radic|5}}, the 5-cell edge.}} The center segment of the 5-cell edge, between the two intersection points, is a 24-cell edge in the smaller 4-polytope, and the red hexagon is a [[24-cell#Great hexagons|24-cell's great hexagon]] in the smaller 4-polytope. Nine other of its great hexagons, in other planes, each intersect with an antipodal pair of these {6} vertices. The dihedral angles between hexagon planes in a 24-cell are 60°, and four great hexagons intersect at each vertex. The 1200 5-cell edges, with two intersection points each, are reduced to 600 distinct vertices, so the smaller 4-polytope is a smaller 120-cell.
The larger 120-cell, of radius {{radic|2}}, is concentric to a smaller instance of itself, of radius {{radic|1}}. Four 5-cell edges meet in 600 tetrahedral vertex figures. Four orthogonally intersecting 5-cell edges meet in cubic vertex figures. The 24-cell's edges also meet in a cubic vertex figure. Two disjoint 5-cell tetrahedral vertex figures are inscribed in alternate positions in each 24-cell cubic vertex figure. The 24-cell edges of the smaller 120-cell are the 5-cell edges of the larger 120-cell, truncated at both ends. The distance between the two points of intersection on the {{radic|5}} chord is the 41.4° chord, of length {{radic|1}} in a {{radic|2}}-radius 120-cell, and length {{radic|1/2}} in a unit-radius 120-cell.
=== Bitruncating the 5-cells ===
The two concentric 120-cells (of radius {{radic|2}} or 1) can be built from 5-cell building blocks, by applying a specific kind of truncation operation to the blocks called [[w:Bitruncation|''bitruncation'']]. This reveals a smaller irregular 4-polytope called the [[w:Bitruncated_5-cell|bitruncated 5-cell]]. The smaller unit-radius 120-cell is the convex hull of a compound of 20 disjoint (and 60 distinct) bitruncated 5-cells, truncated from the 120 disjoint 5-cells of the larger {{Radic|2}}-radius 120-cell.

Its 20 hexagon face planes are not [[24-cell#Great hexagons|24-cell central plane hexagons]], since they intersect each other at their edges, not at their long diameters. The edge length is not the 60° 24-cell edge chord (the {{radic|2}} or 1 radius chord), but the shorter 41.4° chord (of length 1 or {{radic|1/2}}). The long diameter of the hexagon faces is not the 180° 120-cell long diameter chord (of length 2{{radic|2}} or 2) but the 90° 16-cell edge chord (of length 2 or {{radic|2}}). Consequently, three 16-cell tetrahedron cells (from three disjoint 16-cells) are inscribed in each truncated tetrahedron, at the three vertices of each face triangle.
The truncated tetrahedron cell is the truncation of a tetrahedral cell of one of the 120-cell's 5-cells. The four smaller tetrahedra truncated from the corners of the 5-cell tetrahedron lie outside the bitruncated 5-cell, in the space between the larger-radius and smaller-radius 120-cells. Their edges are 25.2° chords (of length 1/𝜙 or {{radic|0.19}}). The truncated tetrahedron edges (of length 1 or {{radic|1/2}}) are 41.4° center sections of 104.5° 5-cell edge chords (of length {{radic|5}} or {{radic|5/2}}). The shorter diagonal of the hexagon faces is the 75.5° chord (of length {{radic|3}} or {{radic|1.5}}), which is the 180° complement of the 104.5° 5-cell edge chord.
The 3-dimensional surface of the bitruncated 5-cell is a honeycomb of 10 truncated tetrahedron cells, truncated from the 5 tetrahedron cells of a 5-cell (each tetrahedron being truncated in two different ways). The truncated tetrahedra are joined face-to-face in a 3-sphere-filling honeycomb (like the cells of any 4-polytope), at both their hexagon and triangle faces. Each hexagonal face of the truncated tetrahedron is joined in complementary orientation to the neighboring truncated tetrahedron. Four truncated tetrahedra meet at each edge, which is shared by two hexagons and one triangle of each cell.
The 30-point bitruncated 5-cell is also the convex common core (spatial [[w:Intersection|intersection]]) of six 5-point 5-cells in dual position. These six 5-cells are completely disjoint: they share no vertices, but their edges intersect orthogonally, at two points on each edge. Four 5-cell edges, from four of the six 5-cells, cross orthogonally in 30 places, the two intersection points on 60 edges: the 30 vertices of a bitruncated 5-cell. The six 5-cells are three dual pairs (in two different ways) of the self-dual 5-cell: six pairs of duals reciprocated at their common midsphere. Each dual pair intersects at just one of the two intersection points on each edge.{{Sfn|Klitzing|2025|loc=''sted'' (Stellated Decachoron)|ps=; [https://bendwavy.org/klitzing/incmats/sted.htm ''sted''] is the compound of two [https://bendwavy.org/klitzing/incmats/pen.htm ''pen'' (Pentachoron)] in dual position. Their intersection core ("Admiral of the fleet") is [https://bendwavy.org/klitzing/incmats/deca.htm ''deca'' (decachoron aka bitruncated pentachoron)].}}
The six 5-cells form a compound that is a stellated 4-polytope with 30 star-points, inscribed in the 120-cell.{{Efn|The stellated compound of six 5-cells in dual position is three pairs of 5-cells reciprocated at their common midsphere. It is composed of dual pairs of the [[W:Compound of five tetrahedra|compound of five tetrahedra]], which form the [[W:Compound of ten tetrahedra|compound of ten tetrahedra]]; its 30 tetrahedral cells are three such dual pairs. In the [[W:Compound of five tetrahedra|compound of five tetrahedra]] the edges of the tetrahedra do not intersect. In the [[W:Compound of ten tetrahedra|compound of ten tetrahedra]] they intersect orthogonally, but not at their midpoints. Each edge has two points of intersection on it. The compound of ten tetrahedra is five pairs of dual tetrahedra reciprocated at their common midsphere. It is inscribed in a dodecahedron (its convex hull). Its ''stellation core'' is an icosahedron, but its ''common core'' where the tetrahedron edges intersect is a dodecahedron, the tetrahedrons' convex spatial intersection. The stellated compound of six 5-cells has the analogous property: it is inscribed in a bitruncated 5-cell (its convex hull), and its common core is a smaller bitruncated 5-cell. (Its stellation core is a [[W:Truncated 5-cell#Disphenoidal 30-cell|disphenoidal 30-cell]], its dual polytope.)}} The convex hull of those 30 star-points is a larger bitruncated 5-cell, inscribed in the 120-cell. In the stellated compound of six 5-cells in dual position, the bitruncated 5-cell occurs in two places and two sizes: as both the convex hull, and the convex common core, of the six 5-cells. In the larger 120-cell of radius {{radic|2}}, the convex hull of six 5-cells is a bitruncated 5-cell with 60 edges of length 1 (inscribed in the 120-cell of radius {{radic|2}}), and the convex common core of the six 5-cells is a bitruncated 5-cell with 60 edges of length {{radic|1/2}} (inscribed in the smaller 120-cell of radius 1).
In the 120-cell, 120 disjoint 5-cell building blocks combine in dual position groups of six, to make 60 bitruncated 5-cells inscribed in the self-dual 5-cells' midsphere (at their edge intersections), and also 60 larger bitruncated 5-cells inscribed in the 120-cell, with each of the 600 vertices shared by three bitruncated 5-cells. The 120-cell is the convex hull of a compound of 20 disjoint (60 distinct) 30-point bitruncated 5-cells.{{Sfn|Klitzing|2025|loc= ''teppix'' (tripesic hexacosachoron)|ps=; ''[https://bendwavy.org/klitzing/incmats/teppix.htm teppix]'' is a compound of 60 [https://bendwavy.org/klitzing/incmats/deca.htm ''deca'' (decachoron aka bitruncated pentachoron)] with 3 ''deca'' sharing each vertex.}}
In the previous section we saw that the six 5-cell edges in each central plane intersect at the {6} vertices of the red hexagon, a great hexagon of a 24-cell. Each 5-cell edge, truncated at both ends at those intersection points, is a 24-cell edge of one of the 24-cells inscribed in a smaller 120-cell: the 600 intersection points. In this section we have seen how that truncation of 5-cell edges at both ends is the bitruncation of the 5-cell, and those 5-cell edges, truncated at both ends, are the same length as edges of bitruncated 5-cells inscribed in the larger 120-cell. Bitruncating the {{radic|2}}-radius 120-cell's 120 5-cells reveals a smaller unit-radius 120-cell. Both 120-cells have 24-point 24-cells and 30-point bitruncated 5-cells inscribed in them. The 60° edge length of the 24-cells equals the radius; it is {{radic|2}} times the 41.4° edge length of the bitruncated 5-cells. The 120-cell contains 25 disjoint (225 distinct) 24-cells, and 20 disjoint (60 distinct) bitruncated 5-cells.
The 41.4° edge of the 30-point bitruncated 5-cell is also the triangle face edge we found in Moxness's 60-point (section 8<sub>3</sub>) rhombicosidodecahedron. There are 60 distinct rhombicosidodecahedra and 60 distinct bitruncated 5-cells in the 120-cell, and they share triangle faces. There are five truncated tetrahedra inscribed in each rhombicosidodecahedron, but they are not face-bound to each other; they are cells of five distinct bitruncated 5-cells, and they are face-bound to truncated tetrahedra in other rhombicosidodecahedra. Each triangle face lies over the center of a larger-by-{{radic|2}} 5-cell face inscribed in the rhombicosidodecahedron. Their edges are also 5-cell edges, truncated at both ends, of a larger-radius-by-{{radic|2}} 120-cell.
=== Rectifying the 16-cells ===
Bitruncation is not the only way to truncate a regular polytope, or even the simplest way. The simplest method of truncation is [[w:Rectification_(geometry)|''rectification'']], complete truncation at the midpoint of each edge.
Moreover, the 5-cell is not the only 120-cell building block we can truncate. We saw how bitruncation of the {{radic|2}}-radius 120-cell's 5-cells reveals the smaller unit-radius 120-cell, as the convex hull of a compound of 20 disjoint (60 distinct) bitruncated 5-cells. In the next paragraph we will see how rectification of the {{radic|2}}-radius 120-cell's 16-cells also reveals the smaller unit-radius 120-cell, as the convex hull of a compound of 25 disjoint (225 distinct) 24-cells. Those two operations on the 120-cell are equivalent. They are the same truncation of the 120-cell, which bitruncates 5-cells into bitruncated 5-cells, and also rectifies 16-cells into 24-cells. This single truncation of the 120-cell captures the distant relationship of the 5-cell building blocks and the 16-cell building blocks to each other.
Rectifying a {{radic|2}}-radius 16-cell of edge 2 creates a unit-radius 24-cell of unit edge, which is the compound of three smaller 16-cells. Rectifying one of those inscribed unit-radius 16-cells of edge {{radic|2}} creates a smaller 24-cell of radius and edge {{radic|1/2}}, which is the [[24-cell#Relationships among interior polytopes|common core (intersection]]) of the unit 24-cell and its three inscribed 16-cells. Like the 120-cell itself, the 24-cell is concentric to a smaller instance of itself of {{radic|1/2}} its radius. The common core of each of the 24-cells in the 120-cell is the corresponding 24-cell in the smaller 120-cell.
=== Rectifying the 5-cells ===
In the previous section we bitruncated the 5-cells and rectified the 16-cells, as one combined truncation operation that yields a smaller 120-cell of {{radic|1/2}} the radius. We can also rectify the 5-cells; but that is another distinct truncation operation, that yields a smaller 4-polytope of {{radic|3/8}} the radius.
[[File:Great (12) chords of rectified 5-cell.png|thumb|400px|5-cell edge chords of the radius {{radic|2}} 120-cell in one of its 200 irregular {12} dodecagon central planes. The {6} bitruncation points (two on each of the 104.5° {{radic|5}} 5-cell edges) lie on a smaller 120-cell of radius 1 (the red circle); they are bitruncated 5-cell vertices. The {6} rectification points (at the midpoints of the 5-cell edges) lie on a still smaller 1200-point 4-polytope of radius {{radic|0.75}} ≈ 0.866 (the magenta circle); they are rectified 5-cell vertices.]]
Rectifying the 5-cell creates the 10-point 10-cell semi-regular [[W:Rectified 5-cell|rectified 5-cell]], with 5 tetrahedral cells and 5 octahedral cells. The 3-dimensional surface of the rectified 5-cell is an alternating [[W:Tetrahedral-octahedral honeycomb|tetrahedral-octahedral honeycomb]] of just 5 tetrahedra and 5 octahedra, tessellating the 3-sphere. If the 120 5-cells in a radius {{radic|2}} 120-cell are rectified, the rectified 5-cells lie on a smaller 4-polytope of radius {{radic|3/4}} (the magenta circle in the diagram), inscribed at the 1200 midedges of the 5-cells. This smaller 4-polytope is not a smaller 120-cell; it is the convex hull of a 1200-point compound of two 120-cells. The rectified 5-cell does not occur inscribed in the 120-cell; it only occurs in this compound of two 120-cells, 240 regular 5-cells, and 120 rectified 5-cells.
Each 10-point rectified 5-cell is the convex hull of a stellated compound of two completely orthogonal 5-point 5-cells: five pairs of antipodal vertices. Their edges intersect at the midedge, and they are ''not'' in dual position (not reciprocated at their common 3-sphere). In this stellated compound of two completely orthogonal 5-cells (which does not occur in the 120-cell), the rectified 5-cell occurs in two places and two sizes: as both the convex hull of the vertices, and the convex common core of the midedge intersections.
The edge length of the rectified 5-cell in the smaller 4-polytope of radius {{radic|3/4}} is {{radic|5/4}}. The edge length of the unit-radius rectified 5-cell is {{radic|5/3}}. The rectified 5-cell is characterized by the ratio between its edge and its radius, {{radic|5}} to {{radic|3}}, the way the regular 5-cell is characterized by the ratio {{radic|5}} to {{radic|2}}. In the 120-cell of radius {{radic|2}}, the 104.5° {{radic|5}} chord is the 5-cell edge, and the 75.5° {{radic|3}} chord is the distance between two parallel 5-cell edges (belonging to two disjoint 5-cells). The 104.5° and 75.5° chords are 180° complements, so they form great rectangles in the {12} central planes of the 120-cell (the red rectangles in the diagram). But in the compound of two 120-cells of radius {{radic|3}} (where 120 rectified 5-cells occur), the {{radic|3}} chord is the ''radius'' (not the 75.5° chord), and the {{radic|5}} chord is the rectified 5-cell edge of arc 80.4° (not the 104.5° chord; the 104.5° edge of the 240 regular 5-cells is {{radic|15/2}}).
Like the rectified 5-cell itself, the 80.4° edge chord does not occur anywhere in the 120-cell, so the rectified 5-cell's edges are not the edges of any polytope found in the 120-cell. The rectified 5-cell's significance to the 120-cell is well-hidden, but it has a crucial indirect role as a building block of the 11-cells in the 120-cell.
=== Truncating the 5-cells ===
[[File:Great (12) chords of unit thirds radius.png|thumb|400px|Truncating the 120-cell's 5-cells at ''one-third'' of their edge length produces a smaller 120-cell of ''one-half'' the radius, with vertices at {6} one-third intersection points of the 120° {{Radic|6}} chords (''not'' of the 104.5° {{Radic|5}} 5-cell edge chords). The green {6} hexagon is a 24-cell great hexagon in the resulting smaller-by-one-half 1200-point 4-polytopes. Because there are {12} such intersection points in each {12} central plane, there are two chiral ways to perform this truncation, which produce disjoint 1200-point 4-polytopes.]]
A third simple way to truncate the 5-cell is at one-third of its edge length. This truncation of the 5-cell creates a 20-point, 10-cell semi-regular 4-polytope, known somewhat ambiguously as ''the'' [[w:Truncated_5-cell|truncated 5-cell]], with 5 truncated tetrahedron cells (like the bitruncated 5-cell's), and 5 regular tetrahedron cells (like the rectified 5-cell's).
The 3-dimensional surface of the truncated 5-cell is an alternating honeycomb of 5 truncated tetrahedra and 5 regular tetrahedra. It resembles the rectified 5-cell, with truncated tetrahedra instead of octahedra.
When the regular 5-cell is truncated at ''one-third'' of its edge length, the radius and edge length of the the resulting truncated 5-cell are ''one-half'' the regular 5-cell's radius and edge length. When the 120 5-cells in a 120-cell of radius 2 are truncated at one-third of their edge length, the truncated 5-cells lie on a smaller 120-cell of radius 1. The edge length of the unit-radius truncated 5-cell is {{radic|5/8}}, one-half the unit-radius 5-cell's edge length of {{radic|5/2}}. The rectified 5-cell is characterized by the ratio between its edge and its radius, {{radic|5}} to {{radic|8}}, the way the regular 5-cell is characterized by the ratio {{radic|5}} to {{radic|2}}, and the rectified 5-cell is characterized by the ratio {{radic|5}} to {{radic|3}}.
The 20-point truncated 5-cell is the convex common core of a stellated compound of four 5-cells (the four 5-cells' spatial intersection). The convex common core has half the radius of the convex hull of the compound. The four 5-cells are orthogonal (aligned on the four orthogonal axes), but none of their 20 vertices are antipodal. The 5-cells are ''not'' in dual position (not reciprocated at their common 3-sphere). The 5-cell edges do ''not'' intersect, but truncating the 120-cell's 5-cell edge chords at their one-third points truncates the 120-cell's other chords similarly. It is the 120-cell's 120° chords (of length {{Radic|6}} in a {{Radic|2}}-radius 120-cell, or {{Radic|3}} in a unit-radius 120-cell) which intersect each other at their one-third points. Four edges (one from each 5-cell) intersect orthogonally at just ''one'' of the two one-third intersection points on each of the 2400 120° chords that join vertices of two disjoint 5-cells. There are two chiral ways to perform this truncation of the 120-cell; they use the alternate intersection points on each edge, and produce disjoint 600-point 120-cells.
The 52.25° edge chord of the truncated 5-cell (one-half the 5-cell's 104.5° edge chord) is not among the [[120-cell#Chords|chords of the 120-cell]], so the truncated 5-cell does not occur inscribed in the 120-cell; it occurs only in a compound of four 120-cells, and 480 regular 5-cells, and 120 truncated 5-cells. In the stellated compound of four orthogonal 5-cells (which does not occur in the 120-cell), the truncated 5-cell occurs in two places and two sizes: as both the convex hull of the 20 vertices, and the convex common core (of half the radius of the convex hull) of the 20 intersection points of four orthogonal 120° chords.
=== The three truncations of the 5-cell in the 11-cell ===
These three semi-regular 4-polytopes are closely related simple truncations of the regular 5-cell:
* The 30-point [[w:Bitruncated_5-cell|bitruncated 5-cell]] is the convex hull, and the convex common core, of a stellated compound of six 5-cells.
* The 20-point [[w:Truncated_5-cell|truncated 5-cell]] is the convex hull, and the convex common core, of a stellated compound of four 5-cells.
* The 10-point [[w:Rectified_5-cell|rectified 5-cell]] is the convex hull, and the convex common core, of a stellated compound of two 5-cells.

== Questions regarding Blind's 11-point augmented rectified 5-cell ==
The geometers who categorized the [[W:Blind polytope|Blind polytopes]] in 1979 discovered a semi-regular 11-point convex 4-polytope with 42 equilateral triangle faces and 36 edges, an [[W:Rectified 5-cell#Other forms|augmented rectified 5-cell]]. It is constructed by adding one point to the 10-point (10-cell) [[w:Rectified_5-cell|rectified 5-cell]], raising an octahedral pyramid on one (actually on each) of the 10-cell's 5 octahedral facets, creating another semi-regular convex 4-polytope with 13 tetrahedral and 4 octahedral facets: a 17-cell.
Since the 10-point rectified 5-cell is found in the 120-cell, is this 11-point (17-cell) 4-polytope that is made from it also found in the 120-cell? If so, where exactly, and in what incidence? What is its relation to the tetrahedral and octahedral cells of the [[w:Rectified_5-cell|rectified 5-cell]], and to the truncated tetrahedral cells of the [[w:Truncated_5-cell|truncated 5-cell]] and [[w:Bitruncated_5-cell|bitruncated 5-cell]]?
What is its relation to the 120-cell's 5-cell edge {30/11} chord, and the isoclinic rotation of period 30 over that chord, which takes hemi-icosahedral rhombicosidodecahedron cells of the 11-cell to each other?
Is the 11-point Blind 4-polytope the realization of the abstract 11-point 11-cell?
== The 11-cell's real elements ==
We seek an object in the 120-cell which is the realization of the abstract 11-cell. The real 11-cell has section 8<sub>3</sub> rhombicosidodecahedra, while the abstract 11-cell has hemi-icosahedron cells. How are the section 8<sub>3</sub> rhombicosidodecahedra different than the abstract hemi-icosahedra?
Consider their incidences, previously established:
* Each 11-cell contains 11 of the 120-cell's 120 completely disjoint 5-cells.
* Each hemi-icosahedron shares a face with 10 distinct 5-cells, and is completely disjoint from 1 of the 5-cells. Each 5-cell shares 1 of its 10 faces with each of 10 hemi-icosahedra, and is completely disjoint from 1 hemi-icosahedron.
* Each rhombicosidodecahedron shares a face with 20 distinct 5-cells, and is completely disjoint from 100 of the 5-cells.{{Efn|Each rhombicosidodecahedron contains only 20 5-cell faces, each from a distinct 5-cell, so it is face-disjoint from 100 of the 5-cells. It contains only 60 5-cell edges, so it is edge-disjoint from those 100 5-cells. It contains only 60 5-cell vertices, so it is vertex-disjoint from those 100 5-cells.}} Each 5-cell shares 1 of its 10 faces with each of 10 rhombicosidodecahedra, and is completely disjoint from 50 rhombicosidodecahedra.
* Each hemi-icosahedron shares its 10 faces (each containing 3 distinct 5-cell edges) with 10 other hemi-icosahedra.
* Each rhombicosidodecahedron shares its 10 {12} central planes (each containing 6 disjoint 5-cell edges) with 10 other rhombicosidodecahedra.
The abstract hemi-icosahedron's 5-cell faces do not actually meet at an edge; each hemi-icosahedron face is actually two 5-cell faces in different places; and 5-cell faces are disjoint in the rhombicosidodecahedra and in the 11-cell. Clearly, the 5-cell edges are not the 11-cell's real edges. The actual 11-cell edge chord is not the 5-cell edge {30/8} chord of length {{radic|5}}, but the longer {30/10) chord of length {{radic|6}}. This ''isocline chord'' of the 5-cell (and the 24-cell) is the ''rotation'' e''dge chord'' of the 11-cell.
The 5-cell faces are not the real 11-cell's faces. The true face of the 11-cell is a great triangle of edge length {{radic|6}} (shown in green in the illustration), lying in a {12} central plane. The green great triangle is where two rhombicosidodecahedrons meet face-to-face as cells do. The 3-polytope cells of the six regular convex 4-polytopes meet pairwise at non-central face planes, forming a honeycomb of cells. Four of the regular 4-polytopes are also compounds of smaller regular 4-polytopes that meet pairwise at central planes. The simplest case is the 16-point (8-cell) tesseract, a non-disjoint compound of two 8-point (16-cells), which meet 2 at a great hexagon central plane. The 24-point (24-cell) is a non-disjoint compound of three 16-point (8-cell) tesseracts, which meet 2 at a great hexagon central plane. The 120-point (600-cell) and the 600-point (120-cell) are also compounds of smaller 4-polytopes, which meet 2 at a central plane. All these regular convex 4-polytopes are a honeycomb of volumetrically disjoint 3-polytope cells, ''and also'' an "inside out honeycomb" compound of smaller 4-polytope "hypercells", with their shared "faces" on the inside, in their central rotation planes.
Like these other 4-polytopes, the 11-cell is a compound of non-disjoint 4-polytope elements meeting 2 at a central plane. Like these other 4-polytopes, it is also an assembly of volumetrically disjoint 3-polytope cells (they are tetrahedral cells of 5-cells), but let us also identify its 4-polytope elements. Each of its 4-polytope "hypercells" is comprised of selected parts of two disjoint polyhedra in different places: a completely orthogonal pair of 60-point (section 8<sub>3</sub>) rhombicosidodecahedrons. Together those selected parts occupy all 4 dimensions, not just a 3-dimensional polyhedral section, and comprise an 11-point, 10-edge, 15-face 4-polytope. The 11-cell is the non-disjoint compound of 11 of these 11-point 4-polytope "hypercells".
The real 11-cell face is a {{Radic|6}} triangle in the {12} central plane parallel to two 5-cell face planes, which lie {{Radic|3}} above and {{Radic|3}} below it. The orthogonal distance between the two 5-cell faces is another {30/10} chord of length {{Radic|6}}, which joins their opposing vertices. That chord is another great triangle edge, in another {12} central plane, but it does not intersect any vertex of the parallel {12} central plane.
We found previously that the abstract hemi-icosahedron face was a {{radic|5}} 5-cell face; then that it was two 5-cell faces in disjoint 5-cells; then that it was really a {{radic|6}} great triangle in a central plane. These findings are not contradictory. The abstract hemi-icosahedron face is realized in a real rhombicosidodecahedron as a rigid object composed of these three parallel triangles. We will visualize that 9-point polyhedron precisely later, but hold the thought that an abstract 11-cell ''face'' is really a ''polyhedron''. This makes sense since the abstract 11-cell ''cell'' is really a ''4-polytope''. Once again, the 11-cell has something to teach us about interdimensional relationships, and the nature of dimensional analogy.
The {12} central plane contains 4 disjoint great triangles (11-cell faces) in distinct rotational orientations, from 4 distinct 11-cells (although to reduce clutter only one of them is shown in green in the illustration). The {12} is the central plane of four distinct 9-point polyhedra, because it contains four distinct great triangles. The two parallel 5-cell face planes also contain triangles (5-cell faces), but these face planes are only {6}s, not {12}s. Each face plane contains only two 5-cell face triangles in opposing rotational orientations, not four triangles, because two of the four distinct 9-point polyhedra share a 5-cell face, the same way two tetrahedral cells of the 5-cell share the face. Pairs of distinct 9-point polyhedra form a 12-point polyhedron with two opposing 5-cell faces, parallel to a hexagon in the central plane between them.{{Efn|There are two regular great hexagons of edge length {{radic|2}} inscribed in each irregular {12} great dodecagon, although to reduce clutter they are not shown explicitly in this illustration. They are the famous [[24-cell#Great hexagons|24-cell great hexagons]]; each 24-cell has 16 of them. Each has two {{radic|6}} [[24-cell#Great triangles|great triangles]] inscribed in it.}} In each of 10 sets of three parallel planes (two 5-cell face planes on either side of a {12} central plane), we find four 9-point polyhedra (four sets of three parallel triangles), paired as two 12-point polyhedra (two sets of two parallel triangles with a parallel hexagon between them). The two opposing 5-cell faces in each {6} face plane belong to two disjoint 5-cells, and also to two distinct rhombicosidodecahedra. The 10 9-point polyhedra are inscribed in a single rhombicosidodecahedron, but the 12-point polyhedra are not.
== The 11-cell rotation ==
Eleven rhombicosidodecahedra are pairwise adjacent in two ways: (1) they are in contact, sharing central planes pairwise, similar to the way two cells of a 4-polytope are bound together at a shared face, and (2) they occupy adjacent Clifford parallel rotational positions in various 30-position isoclinic rotations, not in contact at all, but separated at every vertex by the same small distance. For each pair of rhombicosidodecahedra, these two kinds of adjacency occur in different places. There are places where they share a {{Radic|6}} triangle in a central plane, and other places where their two {{Radic|6}} triangles lie nearby, Clifford parallel, in adjacent positions of an isoclinic rotation which takes them to each other. The rotation takes entire rhombicosidodecahedra to each other's positions, in fact it takes all 60 rhombicosidodecahedra at once to each other's positions; an isoclinic rotation moves everything at once, altogether in parallel, in many different orthogonal directions at once.
This is rather confusing to visualize, but let us try. In this case, the completely orthogonal invariant planes of the isoclinic rotation are pairs of {12} central planes. The 120-cell's 100 completely orthogonal pairs of {12} central planes all rotate at once, by the same displacement angle in each step of the rotation. In this case the angle is 120°, the arc of one edge of a {{Radic|6}} triangle in each central plane. Visualize 800 spherical triangles (or 200 irregular dodecagons, since there are 4 great triangles in each {12} central plane), all rotating like wheels. Now consider that they are 100 completely orthogonal pairs of wheels. Each is not only rotating like a wheel, it is also being rotated sideways like a coin flipping, each vertex moving on a sideways-moving rotating wheel. The actual path through space of each vertex is a closed spiral, a circular helix.
We are visualizing this as a coin rotating like a wheel while it flips sideways in space at the same time, because that is the closest thing to it we have observed in life, but it is more than that. A coin's twisting rotation takes place only in three dimensions: as a wheel in one 2-dimensional plane, and as a flipped coin in another 2-dimensional plane, but those two planes share an axis, because in 3-space there are only 3 orthogonal axes and 3 orthogonal planes through a central point. In 4-space there are 4 orthogonal axes and 6 orthogonal planes through a point (including 3 pairs of [[W:Completely orthogonal|completely orthogonal]] planes which intersect only at the central point, not anywhere in a line). 4-space is potentially very confusing, but the essential thing to understand about its 4 axes is that 4-space is simply roomier. It is more commodious than the 3-space we are confined in, and it has room to spread out in surprising new ways, such as the way two orthogonal circles need not be crammed into sharing an axis, as they must in 3-space. What this means for our visualization process is that we must relax our cramped view of space, and try to see the two completely orthogonal sideways-moving wheels correctly: each occupies a fully independent 2-axis 2-dimensional plane. It is easier to picture their motions ''incorrectly'', the way they would have to happen in 3-space, but a double rotation in 4-space, which we are not in the habit of visualizing correctly because it is unprecedented in our three-dimensional experience, is nonetheless accessible to the human visual imagination, which is a very powerful image processing engine that understands dimensional analogy really well.

== The 11-cell Hopf fibration ==
Most wise children who succeed in building the 120-cell (the picture on the cover of the box of building blocks) do so their first time by assembling it like a round jig-saw puzzle, out of 12 rings of dodecahedral building blocks.{{Sfn|Schleimer & Segerman|2013|loc=''Puzzling the 120-cell''}} Each ring starts out as a stack of 10 dodecahedra piled face-to-pentagon-face, which must then be bent into a circle in the fourth dimension, bringing its top and bottom pentagons together. The entire 120-cell can then be assembled from exactly 12 of these rings, such that every dodecahedron is in contact with 12 other dodecahedra at its 12 pentagon faces, if and only if the wise child learns to link the 12 rings together, so that each passes through all the others. This bundle of 12 interlinked rings of 10 dodecahedra is the 120-cell.
This building process is very clearly described by Goucher in his section of the Wikipedia article on the 120-cell entitled ''[[120-cell#Visualization|§Visualization]]''.{{Sfn|Ruen & Goucher et al. eds. 120-cell|2024|loc=Goucher's ''[[120-cell#Visualization|§Visualization]]'' describes the torus decomposition of the 120-cell into rings two different ways; his subsection ''[[120-cell#Intertwining rings|§Intertwining rings]]'' describes the discrete Hopf fibration of 12 linked rings of 10 dodecahedra}} Goucher was not the first to describe the dodecahedral Hopf fibration of the 120-cell, as the numerous previously published papers cited in the Wikipedia article make clear, but his description of its multi-faceted geometry is also the clearest set of instructions available for how to build it.
The [[W:Hopf fibration|Hopf fibration]] is the general dimensional analogy between the 2-sphere and 3-sphere, which enables us to make a distinct Hopf map describing each special case dimensional analogy between a discrete 3-polytope and 4-polytope. A Hopf map describes a fiber bundle of linked disjoint great circles on the [[W:Clifford torus|Clifford torus]] completely filling the 3-sphere, where each great circle is conflated to a single point on the dimensionally analogous 2-sphere map. Each map of a discrete fibration is an abstract 3-polytope of the real 4-polytope, mapping a particular set of its rings. The Hopf fibration has been studied and described by many mathematicians, some of whom like Goucher have also described it geometrically in succinct English so the rest of us can visualize it.{{Sfn|Dorst|2019|loc=§1. Villarceau Circles|p=44|ps=; "In mathematics, the path that the (1, 1) knot on the torus traces is also known as a [[W:Villarceau circle|Villarceau circle]].
Villarceau circles are usually introduced as two intersecting circles that are the cross-section of a torus by a well-chosen plane cutting it.
Picking one such circle and rotating it around the torus axis, the resulting family of circles can be used to rule the torus.
By nesting tori smartly, the collection of all such circles then form a [[W:Hopf fibration|Hopf fibration]].... we prefer to consider the Villarceau circle as the (1, 1) torus knot rather than as a planar cut."}}
A dimensional analogy is a finding that some real ''n''-polytope is an abstraction of some other real polytope in a space of higher ''n'', where the ''n''-polytope is embedded in some distinct manner in that higher-dimensional space. A Hopf map is a general example, an abstract 3-polytope embedded in 4-space as a rotation of a discrete 4-polytope on the 3-sphere. The crucial point is that it is the rotation object in 4-space which is the real object, and the map in 3-space which is only an abstract object (a lossy description of the real object), not the other way around.{{Sfn|Huxley|1937|loc=''Ends and Means: An inquiry into the nature of ideals and into the methods employed for their realization''|ps=; Huxley observed that directed operations determine their objects, not the other way around, because their direction matters; he concluded that since the means ''determine'' the ends,{{Sfn|Sandperl|1974|loc=letter of Saturday, April 3, 1971|pp=13-14|ps=; ''The means determine the ends.''}} they cannot justify them.}}
To a topologist a Hopf map is not necessarily an actual 3-dimensional object within the 4-dimensional object it is a map of, any more than any map is necessarily an object in the domain of the thing it maps, but in the case of the Hopf maps of the characteristic rotations of the regular convex 4-polytopes, each Hopf map is in fact a 3-polytope found somewhere within the 4-polytope. Thus for example the 12-point (regular icosahedron) is the Hopf map of the bundle of 12 interlinked rings of 10 dodecahedra just described. Each axial great circle of a 120-cell ring of dodecahedra (each fiber in the fiber bundle) is conflated to one distinct point on a 12-point (regular icosahedron) map. The characteristic rotation of the 120-cell which takes dodecahedral cells to each other within their respective rings of 10 dodecahedra is described by this Hopf map. Within the 120-cell (the territory mapped) we find an distinct instance of this map for every instance of the rotation it describes. The 120-cell contains 10 600-cells, each of which has 120 vertices, each with a regular icosahedron vertex figure that is the Hopf map of a distinct isoclinic rotation.
In like fashion, we can look within the 120-cell for the Hopf maps of the 11-cell's characteristic rotations. Such a map would tell us how the eleven cells relate to each other, revealing the cells' external structure, in complement to the way Moxness's 60-point rhombicosidodecahedron reveals the cell's internal structure. We have already identified the 11-cell's characteristic rotation, in which the 11 vertices circulate on 11 disjoint {30/11} skew polygrams with {30/11} chord edges. The Hopf map of this rotation of the real 11-cell 4-polytope will be some 3-polytope that is an abstraction of it. Of course that abstract map must be the abstract 3-polytope we began with, the hemi-icosahedron, or more precisely, its realization as Moxness's 60-point rhombicosidodecahedron 3-polytope.
The rhombicosidodecahedron map has 60 vertices, and each vertex must ''lift'' to a disjoint great circle polygon of the 11-cell. The great circle polygons of the 11-cell rotation are its rotation edge polygons, which we found are {{Radic|6}} great triangles with {30/10} chord edges. These 60 disjoint great circle polygons must exactly fill the real 11-cell 4-polytope, comprising all its vertices. Thus the real 11-cell has 180 vertices. The 11 abstract vertices circulate on 11 disjoint 30-position {30/11} skew polygram isoclines, each abstract vertex visiting one-sixth {30} of the 180 vertices during the rotation. Each abstract vertex is a conflation of .. real vertices on .. {30/11} isoclines, and is represented at one time or another during the rotation by .. distinct vertices which its rotating real vertices visit. There are 11 discrete Hopf fibrations of the 11-cell, with 60 disjoint great {3} triangle fibers each, and 11 disjoint skew {30/11} triacontagram isocline fibers each. Each fibration corresponds to a distinct left (and right) instance of the characteristic isoclinic rotation.

This section is not an historical digression, but a deep dive to the heart of the matter, like Coxeter on Todd's perfect pentads. In this case the heart is found in the [[Kinematics of the cuboctahedron|kinematics of the cuboctahedron]],{{Sfn|Christie|2022|loc=''[[Kinematics of the cuboctahedron|Kinematics of the cuboctahedron]]''}} first described by [[W:Buckminster Fuller|Buckminster Fuller]].{{Sfn|Christie: On Fuller's use of language|2024|loc=''[[W:User:Dc.samizdat#Bucky Fuller and the languages of geometry|Bucky Fuller and the languages of geometry'']]}}
After inventing the rigid geodesic dome, Fuller studied a family of domes which have no continuous compression skeleton, but only disjoint rigid beams joined by tension cables. Fuller called these envelopes ''tension integrity structures'', because they possess independent tension and compression elements, but no elements which do both. One of the simplest [[w:Tensegrity|tensegrity]] structures is the [[w:Tensegrity#Tensegrity_icosahedra|tensegrity icosahedron]], first described by [[W:Kenneth Snelson|Kenneth Snelson]], a master student of Fuller's.{{Efn|Fuller failed to credit [[W:Kenneth Snelson|Snelson]] for the first ascent of the tensegrity icosahedron, a sad lapse for a great educator, as if Coxeter had not gracefully acknowleged Grünbaum.

Buckminster Fuller|publisher=Museum and Arts Center, 1948-1949|place=Black Mountain College|url=https://www.blackmountaincollege.org/buckminster-fuller}}</ref> where Fuller taught the geodesic domes he had invented, and the nascent principles of tension integrity geodesics he was exploring. It would have burnished Fuller's own reputation to gratefully acknowledge his exceptionally quick student's discovery.

Snelson said that he then conceived it on his own, built the first physical model, and presented it to Fuller.}}</ref>|name=Snelson and Fuller}}
A tensegrity icosahedron is an icosahedral geodesic sphere whose 6 orthogonal reflex compression struts float gently in space, linked only by 24 tension cables which frame equilateral faces of the icosahedron, the whole 2-sphere expanding and contracting symmetrically with ''infinitesimal mobility'', a spring-like symmetrical motion leveraged from whatever tiny amount of elasticity remains in the steel struts and cables.
The polyhedron that is the basis for this flexible structure is the Jessen's icosahedron, that we found 10 of in Moxness's 60-point rhombicosidodecahedron, the real cell of the 11-cell. The Jessen's was named by [[w:Adrien_Douady|Douady]] the ''six-beaked shaddock'' because it resembles the fish whose normal affect is with their mouth 90° open, but a cubical shadfish with mouths on all six sides. At the limits, the gender neutral shad can open their six beaks all the way, until they become flat squares and they becomes a cuboctahedron, or they can shut them all tight like a turtle retracting into their octahedron shell. The six mouths always move in unison. This is [[Kinematics of the cuboctahedron#Jitterbug transformations|Fuller's ''jitterbug'' transformation]] of the 12-point ''vector equilibrium'', his name for the unstable [[Kinematics of the cuboctahedron|kinematically flexing cuboctahedron]]. Fuller found that its always-symmetric transformation through 4 distinct forms of the same 12-vertex polyhedron was a closed cycle with two equilibrium points, one stable and the other unstable. The shad's normal 90° open visage is the stable point, the shape the [[Kinematics_of_the_cuboctahedron#Elastic-edge transformation|elastic tensegrity icosahedron]] rests in and strives to return to. The widest-open square-faced cuboctahedron is the unstable inflection point, where the shad gets to decide non-deterministically (that is, without being compelled one way or the other) whether or not to do their ''really'' odd trick -- where they flip their 6 jaws 90 degrees in their 6 faces and shut their 6 beaks on the opposite axis of their squares than the one they opened them on -- or whether they will just shut them all the same way again. Interestingly, the regular icosahedron is one of the shad's guises too, just slightly more gaping than their normal visage. Fuller made a meal of the shad, finding all the insightful things to say about the kinematics of the only fish who can make their edge length exactly the same size as their radius, when they open their mouths all the way. Fuller built physical models of the 12-point vector equilibrium, and even gave demonstrations to audiences of the flexible shad, opening and closing their mouths in spherical synchrony, their 4 pairs of opposite equilateral triangles spiraling toward and away from each other in parallel, always opposed like the two triangles inscribed in a hexagon, counter-rotating like dual [[W:Propellor|tri-propellors]] as they dance toward each other until their edges meet in an octahedron (a hexad), then backing away again while still rotating in the same directions. All this was overlaid with Fuller's own deep commentary, in physical language anyone can understand. Bucky flew the shad through the inflection points in its [[W:Spinor|spinor]] orbit, explaining its [[W:Möbius_loop|Möbius loop]] with vivid apt similes like trimming a submarine's ballast tanks, stalling an airplane at apogee, and nature's abhorrence of the unstable equilibrium point.{{Sfn|Fuller|1975|ps=; In this film Fuller carefully folds a model of the cuboctahedron made of rigid struts with flexible joints through the entire transformation cycle; he also shows how a rigid regular icosahedron can be rotated inside an inscribing "vector edge cube" (a cube with an octahedron inscribed in it), keeping the 12 vertices on the surface of the cube (and on the edges of the octahedron inscribed in the cube) at all times.}}
Earlier, we noticed 10 Jessen's inscribed in each 60-point rhombicosidodecahedron central section of the 120-cell (each real hemi-icosahedron). Each rhombicosidodecahedron is a compound of 5 disjoint Jessen's, in two different ways, just the way the 120-cell is a compound of 5 disjoint 600-cells, in two different ways. In the rhombicosidodecahedron each regular icosahedron vertex has been replaced by the five vertices of a little pentagon face (a 120-cell face), and the regular icosahedron has been replaced by 5 disjoint Jessen's icosahedra.{{Efn|name=compound of 5 cuboctahedra}} The 3 pairs of parallel 5-cell edges in each Jessen's lie a bit uncertainly, infinitesimally mobile and [[Kinematics of the cuboctahedron#Elastic-edge transformation|behaving like the struts of a tensegrity icosahedron]], so we can push any parallel pair of them apart or together infinitesimally, making each Jessen's icosahedron expand or contract infinitesimally. All 600 Jessen's, all 60 rhombicosidodecahedra, and the 120-cell itself expand or contract infinitesimally, together.{{Efn|name=tensegity 120-cell}} Expansion and contraction are Boole Stott's operators of dimensional analogy, and that infinitesimal mobility is the infinite calculus of inter-dimensional symmetry.
The Jessen's unique element set is its 6 long reflex edges, which occur in 3 parallel opposing pairs. Each pair lies in its own central plane, and the 3 central planes are the orthogonal central planes of the octahedron, the orthonormal (x,y), (y,z), and (x,z) planes of a Cartesian basis frame. The 6 reflex edges are all disjoint from one another, but each pair of them forms a merely conceptual great rectangle with the pair of invisible exterior chords that lies in the same central plane. These three great rectangles are storied elements in topology, the [[w:Borromean_rings|Borromean rings]]. They are three rectangular chain links that pass through each other and would not be separated even if all the other cables in the tensegrity icosahedron were cut; it would fall flat but not apart, provided of course that it had those 6 invisible exterior chords as still uncut cables.
[[File:Jessen's √2 radius dimensions.png|thumb|400px|The hemi-icosahedral 60-point rhombicosidodecahedron cell of the 11-cell is a compound of 5 of this 12-point Jessen's icosahedron, shown here on a {{radic|2}}-radius 3-sphere with {{radic|5}} reflex edges. It has an inscribed {{radic|1.5}} green cube. This is a ''vertex figure'' of the 120-cell. The center point is also a vertex of the 120-cell.]]
As a matter of convenience in this paper, we have used {{radic|2}}-radius metrics for 3-sphere polytopes, so e.g. the 5-cell edge is {{radic|5}}, where in unit-radius coordinates it would be {{Radic|5/2}}. Here we give two illustrations of the Jessen's using two different metrics: the 2-sphere Jessen's has a {{radic|5}} diameter, and the 3-sphere Jessen's has a {{radic|2}} radius. This reveals a curiously cyclic way in which our 2-sphere and 3-sphere metrics correspond. In the embedding into 4-space the characteristic root factors of the Jessen's seem to have moved around. In particular, the {{radic|5}} chord has moved to the former {{radic|4}} chord.
We might have expected to find the 6-point hemi-icosahedron's 5-cell triangular faces identified with the Jessen's 8 equilateral triangle faces somehow, but they are not the same size, so that is not the way the two polytopes are identified. The {{radic|5}} reflex edges of the Jessen's are the 5-cell edges. A 5-cell face has its three {{radic|5}} edges in three different Jessen's icosahedra.
The Jessen's is not a cell, but one of the 120-cell's vertex figures, like the [[600-cell#Icosahedra|120 regular icosahedron vertex figures in the 600-cell]]. That is why we find 600 Jessen's, of course. The center point in this Jessen's illustration is another ''vertex'' of the 120-cell, not the empty center of a cell.{{Efn|The 13 vertices of the illustration which include its center point lie in the curved 3-space of the 3-sphere, on the 120-cell's surface. In 4-space, this object is an [[W:Icosahedral pyramid|icosahedral pyramid]] with a Jessen's icosahedron as its base, and the apical center vertex as its apex. The center point in the illustration is a vertex of the 120-cell, and the center of the curved Jessen's, and the apex of the icosahedral pyramid, but it is not the center point in 4-space of a flat 3-dimensional Jessen's icosahedron. The center point of the base Jessen's icosahedron is a point inside the 120-cell, not a 120-cell vertex on its surface. It lies in the same 3-dimensional flat-slice hyperplane as the 12 vertices of the base Jessen's icosahedron, directly below the 13th 120-cell vertex.}}
Each Jessen's includes the central apex vertex, {{radic|2}} radii, {{radic|2}} edges and {{radic|5}} chords of a vertex figure around the 120-cell vertex at its center. The {{radic|2}} face edges are 24-cell edges (also tesseract edges), and the inscribed green cube is the 24-cell's cube vertex figure. The 8 {{radic|2}} face triangles occur in 8 distinct 24-cells that meet at the apex vertex.{{Efn|Eight 24-cells meet at each vertex of a [[24-cell#Radially equilateral honeycomb|honeycomb of 24-cells]]: each one meets its opposite at that shared vertex, and the six others at a shared octahedral cell.{{Efn|In the 600-cell, which contains [[600-cell#Twenty-five 24-cells|25 24-cells]], 5 24-cells meet at each vertex. Each pair of 24-cells at the vertex meets at one of 200 distinct great hexagon central planes. Each 24-cell shares one of its great hexagons with 16 other 24-cells, and is completely disjoint from 8 other 24-cells. In the 120-cell, which contains 10 600-cells (5 disjoint 600-cells two different ways) and 225 24-cells (25 disjoint 24-cells), 8 24-cells meet at each vertex. Each 24-cell shares one of its great hexagons with 16 other 24-cells, and is completely disjoint from 208 other 24-cells. But since in the 120-cell the great hexagons lie in pairs in one of 200 {12} central planes (containing 400 great hexagons), each 24-cell shares one of its {12} central ''planes'' with .. other 24-cells.}}}} This Jessen's vertex figure includes 5-cell edges and 24-cell edges (which are also tesseract edges), so it is descriptive of the relationship between those regular 4-polytopes, but it does not include any 120-cell edges or 600-cell edges, so it has nothing to say, by itself, about the <math>H_4</math> polytopes. It is only a tiny fraction of the 120-cell's full vertex figure, which is a staggeringly complex star: 300 major chords of 15 distinct lengths meet at each of the 600 vertices.
The {{radic|5}} chords are 5-cell edges, connecting vertices in different 24-cells. The 3 pairs of parallel 5-cell edges in each Jessen's lie in 3 orthogonal planes embedded in 4-space, so somewhere there must be a 4th pair of parallel 5-cell edges orthogonal to all of them, in fact three more orthogonal pairs, since 6 orthogonal planes (not just 4) intersect at a point in 4-space. The Jessen's situation is that it lies completely orthogonal to another Jessen's, the vertex figure of the antipodal vertex, and its 3 orthogonal planes (xy, yz, zx) lie completely orthogonal to its antipodal Jessen's planes (wz, wx, wy).{{Efn|name=Six orthogonal planes of the Cartesian basis}} These 6 pairs of parallel 5-cell edges form a 24-point 4-polytope, composed of two completely orthogonal 12-point Jessen's, inscribed in two completely orthogonal rhombicosidodecahedra. This 24-point 4-polytope is not a 24-cell: the 24-cell is not a compound of two 12-point Jessen's. But it turns out that two completely orthogonal 12-point Jessen's indirectly define a 24-point 24-cell. We shall see that their 4-space intersection is a 24-cell.
This finding, of two completely orthogonal 12-point Jessen's isomorphic to a 24-cell, brings Fuller's study of [[w:Tesseract#Radial_equilateral_symmetry|radially equilateral]] vector equilibrium polytopes to its completion in the 24-cell. Fuller began with the hexagon, the 6-point vector equilibrium in 2 dimensions, the only polygon with its radius equal to its edge length. He studied the cuboctahedron, the 12-point vector equilibrium in 3 dimensions, the only polyhedron with its radius equal to its edge length, in all its flexible guises. He discovered its stable equilibrium as the the Jessen's shadfish, with its cube of 6 open mouths and 90° dihedral angles between all its faces, the geometric center of [[WikiJournal Preprints/Kinematics of the cuboctahedron|the cuboctahedron's kinematic transformation]] through the regular polyhedra: tetrahedron, octahedron, Jessen's, regular icosahedron, and cuboctahedron. Fuller's study of kinematic Euclidean geometry did not reach the 4-polytopes, and the ultimate 24-point vector equilibrium in 4 dimensions, the 24-cell, the unique <math>F_4</math> symmetry found only in 4 dimensions. But Fuller led us up to it, through the kinematics of infinitesimal mobility, and that route to it is our clue to the infinite calculus of dimensional expansion and contraction.
We observe this geometry, of two completely orthogonal 12-point Jessen's isomorphic to a 24-cell, only in the 120-cell. The 600-cell contains 12-point Jessen's, but no completely orthogonal pairs of them. The 24-cell individually, and the 25 24-cells in the 600-cell, are not occupied by a pair of 12-point Jessen's. The 24-point 24-cell is not, in fact, a compound of two 12-point Jessen's. While the 120-cell's ratio of disjoint 12-point Jessen's to disjoint 24-point 24-cells is <math>50/25 = 2/1</math>, the ratio of distinct 12-point Jessen's to distinct 24-point 24-cells is <math>600/225 = 8/3 </math>.
We observe another geometry, of 24-cells in dual positions, only in the 120-cell. No two 24-cells in the 600-cell are in dual positions, but in the 120-cell with 225 distinct 24-cells (25 disjoint 24-cells), every 24-cell is in dual position to other 24-cells. The 24-cell is self-dual, and when two 24-cells of the same radius are in dual position, they are completely disjoint with respect to vertices, but they intersect at the midpoints of their 96 orthogonal edges. Since four orthogonal lines intersect at a point in 4-space, in addition to the midedge radius and the two intersecting edges there is a third intersecting edge through each point of contact: ''three'' 24-cells lie in dual positions to each other, with their orthogonal edges intersecting. Three ''pairs'' of 24-cells lie in orthogonal dual positions to each other, sharing no vertices, but the same 96 midedge points.
We also observe this geometry, of 24-cells in dual positions, in the irregular {12} dodecagon central planes, which have two inscribed great {6} hexagons, offset from each other irregularly by a 15.5° arc on one side (a 120-cell edge chord) and a 44.5° arc on the other side. The 600-cell and the 24-cell contain only great {6} hexagon planes. The two inscribed great {6} hexagons in each {12} central plane belong to a pair of 24-cells in dual position.
We observe inscribed 5-cells only in the 120-cell. The 600-cell has <math>5^2 = 25</math> distinct 24-cells inscribed in 120 vertices, and is a regular compound of <math>5</math> disjoint 24-cells in 10 different ways, but it has no inscribed 5-point 5-cells joining corresponding vertices of 5 of its 25 24-cells.{{Efn|The 600-cell does have inscribed 5-point great pentagons joining corresponding vertices of 5 of its 25 24-cells.

These are the same 200 dodecagon central planes illustrated above, which also contain 6 120-cell edges (solid red), which form two opposing ''irregular'' great hexagons (truncated triangles) with the {{radic|5}} chords. The {12} central planes also contain four {{radic|6}} great triangles (green), inscribed in two {{radic|2}} ''regular'' great hexagons. 1200 smaller {{radic|5}} 5-cell ''face'' triangles (blue) occupy 600 other, non-central planes.]]
The Jessen's eight {{radic|6}} triangle faces lie in eight great {6} hexagons in eight {12} central planes of the 120-cell. The Jessen's {{radic|5}} chords lie in great {4} rectangles ({{radic|5}} by {{radic|3}}) in orthogonal central planes of the Jessen's. These are ''also'' {12} central planes of the 120-cell. We can pick out the {{radic|5}} by {{radic|3}} rectangles in the {12} central plane chord diagrams (bounded by red dashed lines). The Jessen's vertex figure is bounded by eight {12} face planes, and divided by six orthogonal {12} central planes, and all 14 planes are {12} central planes of the 120-cell.
The 5-cells' ''face'' planes are ''not'' central planes of the 120-cell. Recall that 10 distinct Jessen's are inscribed in each rhombicosidodecahedron, as two chiral sets of 5 completely disjoint Jessen's, such that two {{radic|5}} 5-cell edges meet at each vertex of the rhombicosidodecahedron. These are two of the four 5-cell edges that meet at each vertex of the 5-cell: edges of a 5-cell face, 20 of which are disjointly inscribed in each rhombicosidodecahedron. In each Jessen's the 6 {{radic|5}} reflex edges are disjoint, and in each rhombicosidodecahedron only two edges meet at each vertex, but in the 120-cell each {{radic|5}} chord meets three others, that lie in three other Jessen's. Each 5-cell face triangle has each edge in a distinct Jessen's, but the face triangle lies in just one rhombicosidodecahedron. The 1200 5-cell face triangles lie in opposing pairs, in one of 600 ''non-central'' hexagon ''face'' planes.
Each of the 60 rhombicosidodecahedra is a compound of 10 Jessen's (5 disjoint Jessen's in two different ways), just the way the 120-cell is a compound of 10 600-cells (5 disjoint 600-cells in two different ways), and the 120-cell's dodecahedron cell is a compound of 10 600-cell tetrahedron cells (5 disjoint tetrahedra in two different ways).
The 600 Jessen's in the 120-cell occur in bundles of 8 disjoint Jessen's, in 4 completely orthogonal pairs, each pair aligned with one of the four axes of the Cartesian coordinate system. Collectively they comprise 3 disjoint 24-cells in orthogonal dual position. They are [[24-cell#Clifford parallel polytopes|Clifford parallel 4-polytopes]], 3 completely disjoint 24-cells 90° apart, and two sets of 4 completely disjoint Jessen's 15.5° apart.
Opposite triangle faces in a Jessen's occupy opposing positions in opposite great hexagons. In contrast, the two completely orthogonal Jessen's are completely disjoint, with completely orthogonal bounding planes that intersect only at one point, the center of the 120-cell. The corresponding {{radic|6}} triangle faces of two completely orthogonal Jessen's occupy completely orthogonal {12} central planes that share no vertices.
If we look again at a single Jessen's, without considering its completely orthogonal twin, we see that it has 3 orthogonal axes, each the rotation axis of a plane of rotation that one of its Borromean rectangles lies in. Because this 12-point (tensegrity icosahedron) Jessen's lies in 4-space, it also has a 4th axis, and by symmetry that axis too must be orthogonal to 4 vertices in the shape of a Borromean rectangle: 4 additional vertices. We see that the 12-point (vertex figure) Jessen's is part of a 16-point (8-cell) tesseract containing 4 orthogonal Borromean rings (not just 3), which should not be surprising since we already found it was part of a 24-point (24-cell) 4-polytope, which contains 3 16-point (8-cell) tesseracts. Each 12-point (6 {{radic|5}} reflex edge) Jessen's is one of 10 concentric Jessen's in a rhombicosidodecahedron, two sets of 5 disjoint Jessen's rotated with respect to each other isoclinically by 12° x 12° = 15.5°, with a total of 60 disjoint {{radic|5}} edges. Each 12-point (24 {{radic|6}} edge) Jessen's is one of 8 concentric Jessen's in two 24-cells in dual positions, rotated with respect to each other isoclinically by 41.4° x 41.4° = 90°, with a total of 192 {{radic|6}} edges.{{Efn|There are 96 {{radic|6}} chords in each 24-cell, linking every other vertex under its 96 {{radic|2}} edges.}} The 24-point 24-cell has 4 Hopf fibrations of 4 hexagonal great circle fibers, so it is a complex of 16 great hexagons, generally not orthogonal to each other, but containing 3 sets of 4 orthogonal great hexagons. Three Borromean link great rectangles are inscribed in each great hexagon, and three tesseracts are inscribed in each 24-cell. Four of the 6 orthogonal [[w:Borromean_rings|Borromean link]] great rectangles in each completely orthogonal pair of Jessen's are inscribed in each tesseract.
== Conclusion ==
Thus we see what the 11-cell really is: not just an [[W:abstract polytope|abstract 4-polytope]], not just a singleton convex 4-polytope, and not just a cell honeycomb on the 3-sphere.{{Sfn|Coxeter|1970|loc=''Twisted Honeycombs''}} Though it is all these things singly, like the regular convex 4-polytopes, it compounds to significantly more.
The 11-cell (singular) is the 11-vertex (17 cell) non-uniform Blind 4-polytope, with 11 non-uniform [[W:Rhombicosidodecahedron|rhombicosidodecahedron]] cells. The abstract regular 11-point (11-cell) has a realization in Euclidean 4-space as this convex 4-polytope, with regular facets and regular triangle faces.
The 11-cell (plural) is subsumed in the 120-cell, just as the regular convex 4-polytopes are. The compound of eleven 11-cells (the ..-cell) and Schoute's compound of five 24-cells (the 600-cell) compound as the quasi-regular 137-point (..-cell) 4-polytope, an object that is the subject of further study.
The 11-cells' realization in the 120-cell as 600 12-point (Legendre vertex figures) captures precisely the geometric relationship between the regular 5-cell and 16-cell (4-simplex and 4-orthoplex), which are both inscribed in the 11-point (17-cell), 137-point (..-cell) and 600-point (120-cell), but are so distantly related to each other that they are not found together anywhere else. More generally, the 11-cells capture the geometric relationship between the ''n''-polytopes of different ''n''.
The symmetry groups of all the regular 4-polytopes are expressed in the 11-cells, paired in a special way with their analogous 3-symmetry groups. It is not simple to state exactly what relates 3-symmetry groups to 4-symmetry groups (there is Dechant's induction theorem),{{Sfn|Dechant|2021|loc=''Clifford Spinors and Root System Induction: H4 and the Grand Antiprism''}} but the 11-cells seem to be the expression of their dimensional analogies.

No doubt this entire essay is too discursive, and mathematically educated writers reach their findings more directly. I have told my story this way, still in a less halting and circuitous manner than it came to me, because it is important to show how I came by my understanding of these objects, since I am not a mathematician. I have been a child building with blocks, and my only guides have been the wiser children who built with the blocks before me, and told me how they did it; that, and my own nearly physical experience building with them, and imagination. I am at pains to show how that can be done, even by as mathematically illiterate a child as I am.

The mentor is a rather dubious [[Soft properties of Boolean functions|soft property]] of a BF. But it seems surprisingly interesting.<br>
It is found in three steps: Creating a [[Boolf-hard#family|family matrix]], getting the senior [[Noble Boolean functions|nobles]] of its rows, and getting their [[Boolf-hard#prefect|prefects]].<br>
The first digits of the prefects form the mentor.

==Walsh permutations==
A Boolean function has a unique mentor for a given arity. The map between mentors can be expressed by four different [[Walsh permutation]]s.<br>
<small style="opacity: .7;">(That is, because a BF can be denoted by its truth table or by its Zhegalkin index. In the images above, they are shown red and green.)</small><br>
In all there are six Walsh permutations, which shall be denoted by Cyrillic letters:
Ж <small>(Zhe)</small>, Ч <small>(Che)</small>, Ш <small>(Sha)</small>, Ю <small>(Yu)</small>, Я <small>(Ya)</small>, Щ <small>(Shcha)</small><br>
Their degree is <math>d = 2^{arity}</math>, i.e. they correspond to invertible binary <math>d \times d</math> matrices.<br>
<small style="opacity: .7;">(The letter Ж is used in two different ways: On its own it represents the permutation. Followed by an integer it represents a BF, identified by its [[Zhegalkin matrix|Zhegalkin index]].)</small>
{{Mentors of Boolean functions/four WP relationships}}
Ч and Ш are both self-inverse. Ю and Я are inverse to each other.
The matrix of Щ is part of a top right Sierpinki triangle. Its diagonals follow a negated XOR pattern. <small style="opacity: .5;">(See [[c:File:Variadic5 antipode; ESAND (ESNOR twin).svg|image]].)</small><br>
The matrix of Ш is almost the same, but with the top right entry inverted.<br>
The matrix of Ч is a family matrix. Its top row is related to that of the Ш matrix. <small>The calculation involves the Zhegalkin twin and reversing the truth table.</small>

{{Collapsible START|relationship between the matrix patterns|collapsed gap-above gap-below}}
The red family matrix has the pattern of Ч.<br>
The green matrix shows the twins of the red rows, and has the pattern of Ю and Я.<br>

The mentor is not simply a bijection between Boolean functions, but between the truth tables for a given arity.<br>
The permutation from Zhegalkin indices to those of their ''n''-ary mentors is '''Ш<sub>''n''</sub>'''. The beginning of Ш<sub>''n''+1</sub> is '''Щ<sub>''n''</sub>'''. <small style="opacity: .5; font-size: 60%;">([[w:Shcha|This letter]] has a little hook on the right.)</small><br>
These two permutations are very similar. They are equal in the first half, and differ by exchanged neighbors in the second.
Neighboring Zhegalkin indices <small>(i.e. 2·''n'' and 2·''n''+1)</small> denote complements.<br>
So although there is no mentor bijection between Boolean functions, there is one between pairs of complements.<br>
Complement and mentor partition the set of all Boolean functions into blocks of size 4 or 2. Such a block shall be called (big or small) ''seminar''.<br>
The Zhegalkin indices in a big seminar are <math>\{ a, a+1, b, b+1 \}</math> with even <math>a</math> and <math>b</math>, so it can be represented by the pair <math>(a, b)</math>.<br>
<small>An example of a seminar is {138, 139, 156, 157}, represented as (138, 156). See [[c:File:Set of 3-ary Boolean functions 12855504354077768210885020350402125463028803369886765232947200.svg|image]]. <small style="opacity: .5;">In the permutation it is represented by the pair (69, 78).</small></small>
The pairs <math>\left( \frac{a}{2}, \frac{b}{2} \right)</math> are the cycles of a self-inverse Walsh permutation of degree <math>2^{arity} - 1</math>. <small style="opacity: .5;">(For arity 3 the degree is 7, and the permuted integers are 0...127.)</small><br>
For arities 1 and 2 this permutation is neutral. For arity 3 is has 64 fixed points <small>(of 128 places, i.e. 1/2)</small>. For arity 5 it has 1024 fixed points <small>(of 32768 places, i.e. 1/32)</small>.<br>

The permutation for arity 4 corresponds to the 15×15 matrix shown on the right.<br>
<small style="opacity: .5; font-size: 60%;">It is described by this vector: (1, 2, 4, 8, 16, 32, 75, 128, 256, 512, 1155, 2048, 4233, 8330, 19252)</small>

Caution! Closed is not the {{Quotation2|opposite|}} of open. {{Quotation2|Most|}} subsets of a metric space are neither open nor closed; there are also some subsets that are both open and closed, e.g., the empty subset and the total space. Open balls are indeed open, and closed balls are indeed closed, see

The boundedness and also compactness depend on the chosen metric. It is important to also have a notion of compactness that is purely topological.

A
{{

is given by a distance function; this implies that two points might be {{Quotation2|closer|}} to each other than two other points. For a mapping
{{
Mapping/display

|pm=
}}
between two metric spaces, one can ask to what extent it is possible to control the distance in the target space {{mat|term= M |pm=}} by the distance in the source space {{mat|term= L |pm=.}} Let
{{
Relationchain
| x
|\in| L

and let
{{

denote the image point. One would like that for a point
{{

that is {{Quotation2|close}} to {{mat|term= x |pm=,}} also the image point {{mathl|term= f(x') |pm=}} is close to {{mathl|term= f(x) |pm=.}} In order to make this intuitive idea more precise, let
{{

the relation
{{

holds. This leads to the concept of a continuous mapping.
{{
inputdefinition
|Metric spaces/Mapping/Continuity in a point/Definition||X=L|Y=M
}}
Instead of working with closed ball neighborhoods, we could work with open ball neighborhoods. The easiest examples of continuous mappings are a constant mapping, the identity of a metric space, and the inclusion
{{
Relationchain

of a subset of a metric space, endowed with the induced metric. See the exercises.

The property (4) shows that continuity is purely a topological property.

A linear mapping is in general not continuous. However, there is a quite simple characterization for continuity of a linear mapping, it is enough to check continuity in the origin. We will see in

The norm and the topology depend only on the underlying real vector space; therefore, we may assume

}}
For a

{{
Relationchain/display
| {{op:Norm|u|}}'
| {{defeq|}} | {{op:Norm| \varphi( u )|}}
||
||
||

we get a norm on {{mat|term= \R^n |pm=.}} Hence, we may directly consider the case
{{
Relationchain
| V
|| \R^n
||
||
||
|pm=.
}}
We compare now an arbitrary norm on {{mat|term= \R^n |pm=}} with the maximum norm and with the Euclidean norm; we know by
{{
Examplelink
|Examplename=

|Nr=

that these two norms are equivalent to each other. Let
{{
Relationchain
| v

||
||

|pm=.
}}
Because of
{{

|\leq| \sum_{i {{=}} 1}^n {{op:Norm|a_i e_i |}}

|\leq| n \cdot {{op:max| {{op:Norm|e_i|}}|i {{=}} 1 {{commadots||}} n |}} {{op:Norm| v |}}_{\rm max}
|pm=,
}}
sufficiently small {{mathl|term= {{op:Norm|-|}}_{\rm max} |pm=-}}open balls are contained in {{mathl|term= {{op:Norm|-|}} |pm=-}}open balls. Therefore, the topology of the maximum norm is as fine as the topology of any other norm. To prove the converse, we consider the identity
{{
Mapping/display
|name=
|\R^n | \R^n
||
|pm=,
}}
where the topology on the left-hand side is given by the Euclidean norm
{{
Extra/Bracket
|text=or maximum norm|
|Ipm=|Epm=,
}}
and on the right-hand side by the norm. The reasoning so far shows that this mapping is continuous. The Euclidean {{mat|term= 1 |pm=-}}sphere {{mat|term= S |pm=}} on the left is
{{
Definitionlink
|compact|
|Context=|

due to the
{{
Factlink

and, according to
{{
Factlink
|Factname=

|Nr=

}}
{{mat|term= S |pm=}} is also compact with respect to the norm {{mathl|term= {{op:Norm|-|}} |pm=.}} We denote this set by {{mat|term= S' |pm=.}} Since {{mat|term= \R^n |pm=}} is a
{{
Definitionlink

with every norm, it follows by
{{
Exerciselink

that {{mat|term= S' |pm=}} is closed. Since the origin does not belong to {{mat|term= S' |pm=,}} there exists a

John|Richard John]] by Spencer Graves about media concentration and how that invites political corruption]]
Columbia University History Professor [[w:Richard R. John|Richard R. John]] discusses the business of communications in the US focusing especially problems stemming from media concentration. Professor John is the author of two books and an editor of eight others related to the business of media and democracy. His two books are:
* (1995) ''Spreading the News: The American Postal System from Franklin to Morse''.<ref>John (1995).</ref>
* (2010) ''Network Nation: Inventing American Telecommunications''.<ref>John (2010).</ref>
More recently, he edited
* with Silberstein-Loeb (2015) ''Making News: The Political Economy of Journalism in Britain and America from the Glorious Revolution to the Internet''.
* with Phillip-Fein (2016) ''Capital Gains: Business and Politics in Twentieth-Century America''.<ref>His other edited volumes include Tedlow and John (1986), and John (2001, 2006, 2012).</ref>
Prof. John discusses his work with Spencer Graves.<ref><!--Spencer Graves-->{{cite Q|Q56452480}}</ref>
== US led the world in numbers of independent newspaper publishers in the nineteenth century ==
Graves said he had seen claims that in the first half of the nineteenth century the US had more independent newspaper publishers than at any other time or place in human history, at least according to Professor John's book with Silberstein-Loeb (2015) on ''The Political Economy of Journalism in Britain and America from the Glorious Revolution to the Internet''. He agreed: "We had an informational environment that fostered decentralization, encouraged the circulation of newspapers to a far flung citizenry with subsidies ... . [I]t was an informational environment in which there were a lot of voices. It was an informational environment in which the total volume of information, in this case printed newspapers, magazines, was much greater than in other countries, and that was understood by Alexis de Tocqueville and others to be a positive good."
Graves asked where he might find numbers to support those claims. Professor John recommended his 1995 book on the early American post office.<ref>John (1995).</ref>
== The media in the US, UK and Germany between the wars ==
When asked to describe the differences between the US, Germany and Britain during the Great Depression and World War II, Professor John began by noting that the information infrastructure in the US was more decentralized. New York City and Chicago were very important, and there was a sharp divide between newspapers and radio. In Great Britain, the BBC had not been a leader in news before the Second World War, and the newspaper press was more consolidated.
For Germany, Heidi J.S. Tworek,<ref><!--Heidi J.S. Tworek-->{{cite Q|Q134875995}}</ref> a fine historian in British Columbia, has written about Germany under Weimar. In the 1920, government administrators wanted to limit what they perceived to be speech that was outside the range of public discourse, and they centralized radio further than it was in the US. This made it easy for Hitler to take it over.
There were clear differences. The US was the most decentralized. By principle, Germany was in the middle. Britain as most centralized. However, in practice, the German infrastructure was the most fragile, easiest to manipulate.
== Trump ==
When asked to describe President Trump's relations with the media, Professor John replied,
{{quote|He's a master of online media. He's like Franklin Roosevelt in that regard with radio or Teddy Roosevelt with newspapers and and photography. He has the rhythms. The cadence of his speech is closely attuned to the affordances of what used to be called [[w:Twitter|Twitter, now X]]. He now has his own social network, a platform, [[w:Truth Social|Truth Social]]. And he recognizes that the most effective online communication is often [[w:Agonism|agonistic]]. It's often critical. It's often very opinionated, very sharply worded. And that has enabled him to dominate many a news cycle.}}
When asked to describe the settlement of President Trump's lawsuits against Meta / Facebook, Professor John replied, "I'm not going to speak on those issues specifically. I don't know enough about them."<ref>This question about Trump's lawsuits against Meta is in the companion video but not the podcast. See also a comment in "Discussion" below.</ref>
== Mayflower and Fairness Doctrines ==
Professor John discussed the [[w:Mayflower doctrine|Mayflower doctrine]],<ref><!--The Mayflower Broadcasting Corporation-->{{cite Q|Q134879570}}</ref> published by the FCC 1941-01-16, after the second world war began but before the US became an official party. This doctrine prohibited radio stations from taking political positions themselves. The FCC hoped thereby to officially encourage the airing of a broad range of opinions without allowing media owners to dominate political discourse.
At that time, radio was a powerful new medium that had already transformed Germany and was transforming Britain. President Roosevelt wanted it to be a conduit for news and not opinion.
After the war, hearings were held in 1948 on the [[w:Mayflower doctrine|Mayflower doctrine]]. This led to a decision in 1949 to repeal that doctrine. Later that year it was replace by the [[w:Fairness doctrine|Fairness doctrine]], which was itself repealed in the late 1980s.
Since that time there has been no effort to police the boundaries of the airwaves. Some say that's good. However, one of the consequences is that it has become very hard to find any legal recourse against those broadcasters, who are challenging norms in ways that can be deleterious to the project of the nation.
== Local News ==
Graves noted that Gao et al. (2018) reported that when local newspapers have died, the cost of local government has increased with increases in head count, executive compensation and the cost of borrowing as the bond rating tended to decline. Those effects lead to increased costs averaging $85 per human per year, which is roughly 0.13 percent of [[w:Gross domestic product|Gross domestic product]] (GDP).
Professor John was asked for his comment. He said, "[[w:Paul Starr|Paul Starr]], a sociologist at Princeton, argued some time ago that if you weaken local news coverage, if you weaken reporting on state houses and city councils, you are inviting political corruption. I think that's a pretty durable generalization."
Graves then noted that McChesney and Nichols have recommended 0.15 percent of GDP be distributed to local news nonprofits with a firewall to prevent political interference and asked for Professor John's comment. He replied,
{{quote|This is a tricky question. [McChesney and Nichols] have done good work. They are committed to a particular non-commercial or anti-commercial vision of the media ecology. I don't share that normative assumption. I think that media have been commercially based in the United States from the eighteenth century to the present. It was commercially based in Britain from the seventeenth century to the present, and, in fact, advertising can serve as a counterweight to tight control. But I do believe that we're at a moment in time when support for local news ... would be beneficial not only to public discourse, but it would also improve the functioning of American institutions.}}
Graves then noted that he had recently interviewed [[Dean Starkman and the watchdog that didn't bark|Dean Starkman]], who makes a distinction between accountability and access journalism. He asked for Professor John's comment. John replied,
{{quote|One of my colleagues, [[w:Todd Gitlin|Todd Gitlin]], used to say that journalists should never interview. They should never curry favor, because if they do, they're inevitably going to see the world through the point of view of whoever it is they're in touch with. I think that's true for some journalists. ... I think it's important that [other journalists] cultivate access, that they're accessible in times of crisis. ... So access journalism has its place.}}
== The need for media reform to improve democracy ==
This article is part of [[:category:Media reform to improve democracy]]. We describe here briefly the motivation for this series.
[[Great American Paradox|One major contributor to the dominant position of the US in the international political economy]] today may have been the [[w:Postal Service Act|US Postal Service Act of 1792]]. Under that act, newspapers were delivered up to 100 miles for a penny when first class postage was between 6 and 25 cents. [[w:Alexis de Tocqueville|Alexis de Tocqueville]], who visited the relatively young United States of America in 1831, wrote, “There is scarcely a hamlet that does not have its own newspaper.”<ref>Tocqueville (1835, p. 93).</ref> McChesney and Nichols estimated that these newspaper subsidies were roughly 0.21 percent of national income (Gross Domestic Project, GDP) in 1841.<ref>McChesney and Nichols (2010, pp. 310-311, note 88).</ref>
At that time, the US probably led the world by far in the number of independent newspaper publishers per capita or per million population. This encouraged literacy and limited political corruption, both of which contributed to making the US a leader in the rate of growth in average annual income (Gross Domestic Product, GDP, per capita). Corruption was also limited by the inability of a small number of publishers to dominate political discourse.
That began to change in the 1850s and 1860s with the introduction of high speed rotary presses, which increased the capital required to start a newspaper.<ref>John and Silberstein-Loeb (2015, p. 80).</ref>
In 1887 [[w:William Randolph Hearst|William Randolph Hearst]] took over management of his father’s ''[[w:San Francisco Examiner|San Francisco Examiner]]''. His success there gave him an appetite for building a newspaper chain. His 1895 purchase of the ''[[w:New York Morning Journal|New York Morning Journal]]'' gave him a second newspaper. By the mid-1920s, he owned 28 newspapers. Consolidation of ownership of the media became easier with the introduction of broadcasting and even easier with the Internet.<ref>John and Silberstein-Loeb (2015). See also Wikiversity, “[[Information is a public good: Designing experiments to improve government]]” and “[[:Category:Media reform to improve democracy]]“.</ref> [[:Category:Media reform to improve democracy|This consolidation seems to be increasing political polarization and violence worldwide]], threatening democracy itself.
=== The threat from loss of newspapers ===
A previous ''Media & Democracy'' interview with Arizona State University accounting professor Roger White on "[[Local newspapers limit malfeasance]]" describes problems that increase as the quality and quantity of news declines and ownership and control of the media become more highly concentrated: Major media too often deflect the public's attention from political corruption enabled by poor media. This too often contributes to other problems like [[w:Scapegoating|scapegoating]] [[w:Immigration|immigrants]] and attacking [[w:Diversity, equity, and inclusion|Diversity, equity, and inclusion]] (DEI) while also facilitating increases in pollution, the cost of borrowing, political polarization and violence, and decreases in workplace safety. More on this is included in other interviews in this ''Media & Democracy'' series available on Wikiversity under [[:Category:Media reform to improve democracy]].
An important quantitative analysis of the problems associated with deficiencies in news is Neff and Pickard (2024). They analyzed data on media funding and democracy in 33 countries. The US has been rated as a "flawed democracy" according to the [[w:Economist Democracy Index|Economist Democracy Index]] and spends substantially less per capita on media compared to the world's leading democracies in Scandinavia and Commonweath countries. They note that commercial media focus primarily on people with money, while publicly-funded media try harder to serve everyone. Public funding is more strongly correlated with democracy than private funding. This recommends increasing public funding for media as a means of strengthening democracy. See also "[[Information is a public good: Designing experiments to improve government]]".

Regarding Trump's lawsuits against Meta, a naive reading of [[w:Section 230|Section 230 of Title 47 of the US Code]] would give Meta a blanked immunity from lawsuits over the content. However, that may not be accurate. The Wikipedia [[w:Lawsuits involving Meta Platforms|Lawsuits involving Meta Platforms]], accessed 2025-06-11, mentions a suit filed 2019-03-28 by the [[w:United States Department of Housing and Urban Development|US Department of Housing and Urban Development]] (HUD) against Facebook over housing discrimination by allowing advertisers to restrict who can see their ads based on certain characteristics, thus violating the federal Fair Housing Act. Facebook agreed to change their system for housing ads and pay $115,000 in penalties, the maximum penalty under the FHA.<ref>{{Cite web |title=Meta settles lawsuit with Justice Department over ad-serving algorithms |url=https://techcrunch.com/2022/06/21/meta-settles-lawsuit-with-justice-department-over-ad-serving-algorithms/ |access-date=2022-06-22 |website=TechCrunch |language=en-US}}</ref>

= '''Chapter 1: Introduction and Evaluation Criteria''' =
== '''1.1 Purpose of Chapter 1''' ==
This chapter introduces the foundational approach of the project. It defines the evaluation criteria we will use to assess and compare cosmological theories and related models. These criteria are designed to be transparent, fair, and applicable across disciplinary boundaries — from physics and astronomy to geology, chemistry, and systems theory.
== '''1.2 Rationale for Using Evaluation Criteria''' ==
Scientific theories often compete within isolated communities, where recognition is tied to tradition, reputation, or alignment with mainstream paradigms. This project proposes a more neutral ground: to evaluate theories based on '''intrinsic quality''', not social acceptance.
Using clear, predefined criteria enables:
* Objective comparison between theories
* Transparent reasoning for inclusion or exclusion
* A structured foundation for AI-assisted analysis
== '''1.3 List of Evaluation Criteria''' ==
Each theory or model will be assessed according to the following criteria. These are not ranked, but considered '''complementary dimensions of scientific value''':
# '''Empirical Adequacy:''' Does the theory fit known observations and experimental data?
# '''Internal Consistency:''' Are the theory’s assumptions, mathematics, and logic self-coherent?
# '''Predictive Power:''' Does the theory make testable predictions that distinguish it from other models?
# '''Cross-Disciplinary Compatibility:''' Is the theory consistent with findings in geology, chemistry, biology, or other fields?
# '''Conceptual Clarity and Simplicity:''' Is the theory elegantly framed and easy to interpret without unnecessary complexity?
# '''Heuristic Value:''' Does the theory stimulate new questions, research, or interdisciplinary insights?
# '''Historical and Philosophical Insight:''' Does the theory integrate or build upon earlier models in a meaningful way?
Detailed star ratings for each theory, based on these criteria, are presented in '''Chapter 8'''.
== '''1.4 Procedure for Adding New Theories''' ==
In line with the inclusive and structured intent of this project, any proposed theory or model will be evaluated using the same criteria (see '''1.3 List of Evaluation Criteria''') and integrated where appropriate into the chapters of this Wikiversity page.
To ensure consistency and clarity, the following rules apply:
'''Mandatory Insertions:'''
* '''Chapter 2: Gravity Theories – Comparison and Mapping'''
If the theory proposes or relies on a specific gravity model (e.g., General Relativity, MOND, Emergent Gravity), it will be mapped here with a brief entry in the theory table.
* '''Chapter 3: Cosmic Expansion and Universe Models'''
All accepted cosmological models must be clearly described in a dedicated subsection of this chapter.
* '''Chapter 8: Critical Evaluation and Future Research Paths'''
Each theory is scored using the evaluation criteria from section 1.3 and added to the AI Evaluation Table.
'''Optional Insertions:'''
These chapters are reserved for theories that affect specific scientific domains:
* '''Chapter 4:''' if the theory addresses planetary or disk formation.
* '''Chapter 5:''' if the theory involves geological evidence or planetary growth.
* '''Chapter 6:''' if biological or paleontological implications are discussed.
* '''Chapter 7:''' if the theory redefines or involves cosmological constants or parameters.
* '''Chapter 9:''' if the theory's development, publication, or challenges are relevant to documentation and transparency.
* '''Chapter 10:''' if specific references, historical context, or acknowledgements need to be added.
This structured approach ensures coherence while allowing new or alternative ideas to be considered on equal footing with established theories.
== '''1.5 Use of AI in Evaluating Theories''' ==
AI (specifically ChatGPT) will apply these criteria when comparing theories, identifying conflicts or synergies, and drafting neutral summaries. The AI does not decide which theory is “true,” but serves as a tool for generating comparisons and identifying theoretical patterns or blind spots.
Human contributors will:
* Approve, question, or refine AI assessments
* Suggest additional theories or data points for consideration
* Monitor the process for epistemic bias or misinterpretation
== '''1.6 Notes on Bias and Inclusion''' ==
The project acknowledges that many valid theories — particularly those outside mainstream academic discourse — are poorly represented in traditional publications or databases. To address this:
* The project will include relevant work from open platforms (e.g., Zenodo, ResearchGate, Wikiversity, Academia.edu).
* Theories will not be excluded based on popularity or institutional origin.
* Arguments must be logical, evidence-based, and presented with intellectual honesty.
== '''1.7 Looking Ahead''' ==
In the next chapters, we will begin applying these criteria to groups of related theories, starting with various gravitational models in Chapter 2. Each theory will be evaluated using a combination of AI-supported summary and human critical review.

== 1.7 '''The Role of AI as Meta-Peer Review''' ==
While this project relies on human oversight and transparent procedures, it also acknowledges the emerging role of Artificial Intelligence (AI) — especially large language models like ChatGPT — as a kind of informal "meta-peer review" system.
Independent theorists, especially those excluded from traditional academic publishing, increasingly consult AI tools to:
* Evaluate internal consistency
* Test mathematical logic and equations
* Check empirical plausibility
* Predict consequences of theoretical assumptions
Though AI output does not replace experimental validation or peer consensus, it can help flag internal contradictions, generate useful predictions, and offer conceptual clarity. As such, AI-assisted analysis may gradually evolve into a **legitimate secondary review system**, especially for theories that challenge or bypass mainstream editorial processes.
This project reflects and formalizes that development: applying AI not as an authority, but as a tool for clarity, critique, and comparison.
== '''1.8 Looking Ahead''' ==
In the next chapters, we will begin applying these criteria to groups of related theories, starting with various gravitational models in Chapter 2. Each theory will be evaluated using a combination of AI-supported summary and human critical review.

=== Optional Insertions for Domain-Specific Context ===
In addition to the core rating in Chapter 8, contributors may request that their theory be referenced in one or more of the following chapters:
* '''Chapter 4''' – if the theory addresses planetary or disk formation.
* '''Chapter 5''' – if geological evidence, Earth expansion, or stratigraphy are relevant.
* '''Chapter 6''' – if biological or paleontological implications are included.
* '''Chapter 7''' – if the theory redefines or involves cosmological constants or universal parameters.
* '''Chapter 9''' – if the development, publication challenges, or authorship history are significant.
* '''Chapter 10''' – for references, historical context, or acknowledgements.
These insertions do not involve separate ratings. They are used to summarize how the theory relates to that domain, and may include an AI-generated comment or brief author-provided summary for clarity.

== '''Chapter 8: Methods, Tools, and AI-Assisted Evaluation''' =
== '''Purpose''' ==
This chapter describes the methodological foundations of the project, including the role of AI in evaluating theories, how contributors interact with the system, and how assessments are recorded, displayed, and updated.
== '''Toolchain and Workflow''' ==
AI tools like ChatGPT are used to analyze, compare, and refine theories
Tables and frameworks are generated collaboratively using open formats
Contributors submit input via email or editing suggestions
Ratings and evaluations are dynamically updated based on ongoing analysis
== '''AI-Based Rating System: Motivation and Procedure''' ==
To support comparative evaluation without personal or institutional bias, this project uses an AI-based rating system. ChatGPT acts as a neutral evaluator, analyzing each theory across clearly defined criteria such as:
Observational Agreement
Internal Logical Consistency
Predictive Value
Compatibility with Other Domains (e.g., geology, biology)
Conceptual Coherence and Simplicity
Each dimension is rated using a 1–5 star system, based on the information provided and the supporting sources that AI can access.
This system is designed to be:
Transparent – Each rating is justified through AI’s large-scale reference analysis.
Dynamic – Contributors may submit additional materials to request re-evaluation.
Consistent – All evaluations are performed by the same AI logic, eliminating personal bias.
Contributors may ask ChatGPT to re-read specific articles, datasets, or theoretical arguments. If new insights are found, ratings will be updated and transparently noted.
This approach represents a shift toward evidence-driven, large-scale comparative review, using AI not as a gatekeeper but as a tool to synthesize and validate.
== '''Open Participation''' ==
This chapter is also where future documentation of the workflow and collaborative mechanisms will be expanded. Users who submit theories are encouraged to:
Describe their framework in terms of assumptions, predictions, and compatibility
Suggest how their model could be tested or falsified
Provide references or original materials for AI evaluation
All analysis is open, and contributors may propose improvements at any time.
== '''8.1 Understanding the Star Ratings''' ==
The AI Evaluation Table below rates theories across seven scientific criteria defined in '''Chapter 1.3'''. Here we provide a full explanation of what each criterion means and how it is applied.
'''1. Empirical Adequacy'''
Does the theory fit known observations and experimental data? High scores require support from astronomy, cosmology, geology, or lab-based physics. Theories that contradict established measurements or lack empirical grounding score lower.
'''2. Internal Consistency'''
Are the theory’s assumptions, mathematics, and logic self-coherent? A consistent theory does not contain contradictions, undefined steps, or ad hoc assumptions.
'''3. Predictive Power'''
Does the theory make clear, testable predictions that distinguish it from others? Theories that anticipate new phenomena or retrodict known data gain higher ratings.
'''4. Cross-Disciplinary Compatibility'''
Is the theory consistent with findings from other scientific fields, such as geology, chemistry, biology, or planetary science? The more compatible it is, the higher the score.
'''5. Conceptual Clarity and Simplicity'''
Is the theory logically simple and intuitively understandable, without unnecessary complexity? This criterion rewards elegance, not oversimplification.
'''6. Heuristic Value'''
Does the theory stimulate new questions, research directions, or rethinking of existing problems? A high score reflects creative scientific potential.
'''7. Historical and Philosophical Insight'''
Does the theory connect meaningfully to the historical development of science or reflect philosophical depth? Theories grounded in tradition or conceptual evolution are valued here.
Each theory receives a rating from ★☆☆☆☆ to ★★★★★ per criterion. The total score (max 35) gives a general measure of its scientific coherence and reach. The reasoning behind the scores is available under each theory or can be requested in more detail.

'''2. Internal Consistency'''
Are the theory’s assumptions, mathematics, and logic self-coherent? A consistent theory does not contain contradictions, undefined steps, or ad hoc assumptions.
'''3. Predictive Power'''
Does the theory make clear, testable predictions that distinguish it from others? Theories that anticipate new phenomena or retrodict known data gain higher ratings.
'''4. Cross-Disciplinary Compatibility'''
Is the theory consistent with findings from other scientific fields, such as geology, chemistry, biology, or planetary science? The more compatible it is, the higher the score.
'''5. Conceptual Clarity and Simplicity'''
Is the theory logically simple and intuitively understandable, without unnecessary complexity? This criterion rewards elegance, not oversimplification.
'''6. Heuristic Value'''
Does the theory stimulate new questions, research directions, or rethinking of existing problems? A high score reflects creative scientific potential.
'''7. Historical and Philosophical Insight'''
Does the theory connect meaningfully to the historical development of science or reflect philosophical depth? Theories grounded in tradition or conceptual evolution are valued here.
Each theory receives a rating from ★☆☆☆☆ to ★★★★★ per criterion. The total score (max 35) gives a general measure of its scientific coherence and reach. The reasoning behind the scores is available under each theory or can be requested in more detail.

These ratings are transparent and intended to support critical evaluation and ongoing refinement of both established and alternative cosmological theories. Constructive feedback, new data, or arguments may lead to adjustments in the scores, provided clear reasoning is presented.
If a contributor or author does not agree with the evaluation or prefers not to have their theory represented under this framework, they may request that all related content and ratings for that theory be removed.

== '''Chapter 8: Methods, Tools, and AI-Assisted Evaluation''' =
== '''Purpose''' ==
This chapter describes the methodological foundations of the project, including the role of AI in evaluating theories, how contributors interact with the system, and how assessments are recorded, displayed, and updated.
== '''Toolchain and Workflow''' ==
AI tools like ChatGPT are used to analyze, compare, and refine theories
Tables and frameworks are generated collaboratively using open formats
Contributors submit input via email or editing suggestions
Ratings and evaluations are dynamically updated based on ongoing analysis
== '''AI-Based Rating System: Motivation and Procedure''' ==
To support comparative evaluation without personal or institutional bias, this project uses an AI-based rating system. ChatGPT acts as a neutral evaluator, analyzing each theory across clearly defined criteria such as:
Observational Agreement
Internal Logical Consistency
Predictive Value
Compatibility with Other Domains (e.g., geology, biology)
Conceptual Coherence and Simplicity
Each dimension is rated using a 1–5 star system, based on the information provided and the supporting sources that AI can access.
This system is designed to be:
Transparent – Each rating is justified through AI’s large-scale reference analysis.
Dynamic – Contributors may submit additional materials to request re-evaluation.
Consistent – All evaluations are performed by the same AI logic, eliminating personal bias.
Contributors may ask ChatGPT to re-read specific articles, datasets, or theoretical arguments. If new insights are found, ratings will be updated and transparently noted.
This approach represents a shift toward evidence-driven, large-scale comparative review, using AI not as a gatekeeper but as a tool to synthesize and validate.
== '''Open Participation''' ==
This chapter is also where future documentation of the workflow and collaborative mechanisms will be expanded. Users who submit theories are encouraged to:
Describe their framework in terms of assumptions, predictions, and compatibility
Suggest how their model could be tested or falsified
Provide references or original materials for AI evaluation
All analysis is open, and contributors may propose improvements at any time.
== '''8.1 Understanding the Star Ratings''' ==
The AI Evaluation Table below rates theories across seven scientific criteria defined in '''Chapter 1.3'''. Here we provide a full explanation of what each criterion means and how it is applied.

Since then, this stance has been embedded in official rhetoric, military programs, state-sponsored education, and symbolic events such as [[Quds Day]].
The rejection of Israel's legitimacy has remained consistent across both hardline and moderate Iranian leaderships. Supreme Leaders Ruhollah Khomeini and [[Ali Khamenei]] have both repeatedly referred to Israel as a "[[Cancer|cancerous]] [[Neoplasm|tumor]]" and publicly called for its elimination. Even reformist leaders and moderate clerics have supported this stance. While the Iranian regime maintains that its opposition is directed at [[Zionism]] rather than at [[Jews]] or [[Judaism]], official propaganda has frequently blurred this distinction, at times incorporating [[Holocaust denial]] and invoking [[Antisemitic trope|antisemitic tropes]].
Iran’s anti-Israel policy is implemented through a centralized institutional framework led by the office of the Supreme Leader and the [[Islamic Revolutionary Guard Corps]] (IRGC). Operational activities are largely carried out via a network of allied non-state actors, including [[Hezbollah]] in [[Lebanon]], the [[Houthis]] in [[Yemen]], [[Hamas]] and [[Palestinian Islamic Jihad]] in the [[Palestinian territories]], and other affiliated groups. These organizations receive sustained Iranian support in the form of funding, weapons, and training, and are collectively referred to by Iranian officials as the "[[Axis of Resistance]]." This proxy network enables Iran to exert influence across multiple fronts while posing an existential threat to Israel through asymmetric conflict. Additionally, statements by senior officials and the regime's hostility toward Israel have led many observers{{which|date=June 2025}} to view [[Nuclear program of Iran|Iran's nuclear ambitions]] as part of a broader strategy to destroy Israel.

Iran has aimed to slowly strangle Israel by keeping it mired in a series of increasingly destructive, unwinnable wars through funneling advanced weaponry and financial backing to groups such as Hezbollah, Hamas, and Palestinian Islamic Jihad. That aggression has compelled Israel to pursue a retaliatory campaign.

Established by Ayatollah Khomeini, [[Quds Day]] (''Ruz-e Qods'', in reference to [[Jerusalem]]) is celebrated annually on the last Friday of [[Ramadan]] and aims to promote Muslim solidarity against Israel.<ref name=":4">{{Cite book |last=Magen |first=Ze'ev |title=Reading revolutionary Iran: the worldview of the Islamic republic's religio-political elite |date=2023 |publisher=De Gruyter |isbn=978-3-11-101810-2 |series=Studies on Modern Orient |location=Berlin, Boston |pages=626}}</ref><ref name="auto"/> Senior clerics, including Ayatollah [[Naser Makarem Shirazi]], have described participation in Quds Day as a form of religious worship (''ebādat''), intended to unite Muslims around the world.<ref name=":4" />
According to an April 2024 report by Iran International, many Iranians see the annual Quds Day event as irrelevant and disconnected from the country's dire social and economic realities.<ref>{{Cite web |last= |first= |date=2024-04-05 |title=Iranians Criticize Quds Day's Futility And Destructive Impact |url=https://www.iranintl.com/en/202404054687 |access-date=2025-06-05 |website=www.iranintl.com |language=en}}</ref>
In 2017, a digital clock was installed in Palestine Square, [[Tehran]] for Quds Day, reportedly counting down to the destruction of Israel.

=== Holocaust denial ===
Until recently, Iran was the only state whose leadership and institutions openly engaged in [[Holocaust denial]] (and at times justification) as part of official ideology.<ref name=":03"/> This rhetoric served to legitimize calls for the destruction of Israel by denying or minimizing the Holocaust, thereby undermining the historical justification for the state's existence and portraying it instead as a product of Western imperialism.<ref name=":032">{{Citation |last=Litvak |first=Meir |title=Iranian Antisemitism and the Holocaust |date=2017 |work=Antisemitism Before and Since the Holocaust: Altered Contexts and Recent Perspectives |pages=205 |editor-last=McElligott |editor-first=Anthony |url=https://doi.org/10.1007/978-3-319-48866-0_9 |access-date=2025-06-16 |place=Cham |publisher=Springer International Publishing |language=en |doi=10.1007/978-3-319-48866-0_9 |isbn=978-3-319-48866-0 |editor2-last=Herf |editor2-first=Jeffrey}}</ref> [[Mohammad-Ali Ramin]], a close advisor to Mahmoud Ahmadinejad, once stated that "the resolution" of the Holocaust issue would lead to the "destruction of Israel."<ref name=":032" />

Iranian media, including outlets aligned with the reformist faction, have accused Israeli intelligence of making efforts to undermine Shi'ite religious rituals and sow sectarian discord.''<ref name=":5">{{Cite book |last=Magen |first=Ze'ev |title=Reading revolutionary Iran: the worldview of the Islamic republic's religio-political elite |date=2023 |publisher=De Gruyter |isbn=978-3-11-101810-2 |series=Studies on Modern Orient |location=Berlin, Boston |pages=625}}</ref>'' In one 2019 example, [[Mossad]] was alleged to have trained Israeli Jews as ''maddahan'' (ritual eulogists) to infiltrate mourning assemblies in Iran and deliberately mislead audiences into cursing or blaspheming.''<ref name=":5" />''
Between 2011 and 2021, Iranian institutions organized dozens of ideologically driven conferences with provocative titles such as ''"Zionism and the [[SARS]] Disease"'', ''"[[Rwandan genocide|Genocide in Rwanda]] and in [[Palestinian genocide accusation|Gaza]]"'' (where only one speaker addressed Rwanda and the remaining fifteen focused on Gaza), and ''"Judaism and [[Hollywood, Los Angeles|Hollywood]]: A Diabolical Conspiracy"'', showing the regime's effort to link Zionism with global ills.''<ref name=":7">{{Cite book |last=Magen |first=Ze'ev |title=Reading revolutionary Iran: the worldview of the Islamic republic's religio-political elite |date=2023 |publisher=De Gruyter |isbn=978-3-11-101810-2 |series=Studies on Modern Orient |location=Berlin, Boston |pages=207–208}}</ref>'' These events, while often poorly attended, are publicly portrayed as major intellectual gatherings, with state media describing a half-empty auditorium as "standing room only" at a conference titled ''"The Jewish Roots of [[MI6|MI-6]]."<ref name=":7" />''

[[Efraim Karsh]], a British–Israeli historian of Middle Eastern politics, has described Iran's posture toward Israel as [[Genocide|genocidal]].<ref name=":0" /> According to American scholar Afshon Ostovar, Iran's campaign against Israel constitutes "the single most destabilizing conflict in the Middle East" and carries "the greatest potential to cause a broader regional war."<ref name=":8" /> American journalist [[Jeffrey Goldberg]] suggests that if Iran acquired nuclear weapons, it would likely intensify its efforts to destroy Israel.<ref name=":9">{{Cite web |last=Goldberg |first=Jeffrey |date=2015-03-09 |title=The Iranian Regime on Israel's Right to Exist |url=https://www.theatlantic.com/international/archive/2015/03/Iranian-View-of-Israel/387085/ |access-date=2025-06-05 |website=The Atlantic |language=en}}</ref>
[[File:Islamic_Republic_of_Iran_Army_Day_2016_(189).jpg|thumb|The words "Death to Israel" in Persian displayed on a parade celebrating Army Day, 2016]]
According to Ze'ev Magen, ''[[Death to Israel]]'' (''marg bar Esra'il''), along with ''[[Death to America]]'', has been a commonly used slogan by Iranian officials for over a quarter of a century.<ref name=":2" /> Magen suggests the call for the conquest of Jerusalem is portrayed as a unifying ''[[jihad]]'' that could redirect Sunni opposition away from Shi'ite Iran, which positions Iran as the vanguard of global Islamic resistance.<ref name=":4"/>
=== Hardliner support within Iran ===
According to [[Mehdi Khalaji]], a new generation of Iranian hardliners, closely tied to the Supreme Leader and the IRGC, has embraced the regime's doctrines, with many believing that Iran is a rising power, the United States is in decline, and that "Israel’s days are numbered."<ref name=":11" />
=== Opposition within Iran ===
[[Sadegh Zibakalam]], an emeritus professor of political science at the [[University of Tehran]], has frequently spoken out against the regime's aggressive policies. He says that the Iranian public, especially the younger generation, is losing interest in the Palestinian issue and even expressing support for figures like Benjamin Netanyahu and Donald Trump. This support does not stem from alignment with their policies, but rather from opposition to the Iranian regime and its backing of groups such as Hamas and Hezbollah. Due to his statements, Zibakalam served an 18-month prison sentence and as of March 2025 was under investigation again, potentially facing further imprisonment.<ref>{{Cite web |last=Azizi |first=Arash |date=2025-03-12 |title=The Iranian Dissident Asking Simple Questions |url=https://www.theatlantic.com/international/archive/2025/03/iran-protest-zibakalam-palestine/682006/ |access-date=2025-06-05 |website=The Atlantic |language=en}}</ref> [[Abdollah Nouri]], a prominent cleric and former interior minister, was sentenced to five years in prison in 1999 (making him the most senior Islamic Republic official to be jailed since the revolution) reportedly for, among other charges, openly challenging Khomeini's doctrine that Israel must be obliterated.<ref>{{Cite book |last=Arjomand |first=Said Amir |title=After Khomeini: Iran under his successors |publisher=Oxford University Press |year=2009 |isbn=978-0-19-539179-4 |location=Oxford ; New York |pages=95–96}}</ref>
=== Jewish religious responses ===
Following the 1979 [[Iranian Revolution]], Jewish religious leaders voiced concern over the potential implications of the new Islamic Republic's policies for Israel and Jewish communities in the region. [[Rabbi Menachem Mendel Schneerson]], known as the [[Lubavitcher Rebbe]], described the revolution as a significant turning point in global politics. In public addresses at the time, he warned that Iran's challenge to the [[United States]] would weaken American influence and embolden hostility toward [[Israel]]. The Rebbe also expressed alarm for the safety of the Jewish community in Iran, which then numbered approximately 50,000, and advocated for a communal day of fasting and prayer in response to the escalating crisis.<ref>{{cite web |last=Shamir |first=Shlomo |title=The Israeli Journalist, Iran, and the Rebbe's Vision |url=https://www.chabad.org/therebbe/article_cdo/aid/2608163/jewish/The-Israeli-Journalist-Iran-and-the-Rebbes-Vision.htm |access-date=2025-06-05 |website=Chabad.org}}</ref>

Since then, this stance has been embedded in official rhetoric, military programs, state-sponsored education, and symbolic events such as [[w:Quds Day|Quds Day]].
The rejection of Israel's legitimacy has remained consistent across both hardline and moderate Iranian leaderships. Supreme Leaders Ruhollah Khomeini and [[w:Ali Khamenei|Ali Khamenei]] have both repeatedly referred to Israel as a "[[Cancer|cancerous]] [[Neoplasm|tumor]]" and publicly called for its elimination. Even reformist leaders and moderate clerics have supported this stance. While the Iranian regime maintains that its opposition is directed at [[Zionism]] rather than at [[Jews]] or [[Judaism]], official propaganda has frequently blurred this distinction, at times incorporating [[Holocaust denial]] and invoking [[w:Antisemitic trope|antisemitic tropes]].
Iran’s anti-Israel policy is implemented through a centralized institutional framework led by the office of the Supreme Leader and the [[Islamic Revolutionary Guard Corps]] (IRGC). Operational activities are largely carried out via a network of allied non-state actors, including [[Hezbollah]] in [[Lebanon]], the [[Houthis]] in [[Yemen]], [[Hamas]] and [[Palestinian Islamic Jihad]] in the [[Palestinian territories]], and other affiliated groups. These organizations receive sustained Iranian support in the form of funding, weapons, and training, and are collectively referred to by Iranian officials as the "[[Axis of Resistance]]." This proxy network enables Iran to exert influence across multiple fronts while posing an existential threat to Israel through asymmetric conflict. Additionally, statements by senior officials and the regime's hostility toward Israel have led many observers{{which|date=June 2025}} to view [[Nuclear program of Iran|Iran's nuclear ambitions]] as part of a broader strategy to destroy Israel.

=== Clerics ===
In 2013, [[Ahmad Alamolhoda]], a prominent Iranian cleric and member of the [[Assembly of Experts]], said the destruction of Israel was "one of the pillars of the Iranian Islamic regime" and said: "We cannot claim that we have no intention of going to war with Israel."<ref name=":9" /> Ayatollah [[Hussein-Ali Montazeri]], once designated as Khomeini’s successor and later a supporter of the reform movement, recalled telling a delegation of reformist parliamentarians that, according to [[Quran 7]], the Jews of Zionism (''yahudiyan-e sahyonizm'') would be afflicted with torment and misery until the [[Judgement Day in Islam|Day of Resurrection]].<ref name=":3">{{Cite book |last=Magen |first=Ze'ev |title=Reading revolutionary Iran: the worldview of the Islamic republic's religio-political elite |date=2023 |publisher=De Gruyter |isbn=978-3-11-101810-2 |series=Studies on Modern Orient |location=Berlin, Boston |pages=127}}</ref> He also cited a 17th-century hadith from ''[[Bihar al-Anwar|Biḥār al-Anwār]]'' in which Imam [[Ja'far al-Sadiq]] is reported to have said three times that those who would ultimately exterminate the Jews (''kasani keh nehayatan yahud ra monqarez mikonand'') would be "the people of [[Qom]]", referring to the Iranian Shi'ite clergy.<ref name=":3" />
In 2010, [[Mohammad Hassan Rahimian]], Khamenei's representative to the [[Mostazafan Foundation]], stated that Iran possesses missile capabilities that would allow it to destroy Israel "in its entirety with a big holocaust."<ref name=":9" /> Ayatollah Mohammad Musavi-e Bojnurdi, a senior jurist known for his association with the reformist [[Iranian Green Movement]], said there was "no room for friendly relations with Israel."<ref name=":3" />

=== Axis of Resistance ===

Iran's refers to its strategic alliance with regional non-state actors, including Hezbollah in Lebanon, Hamas and Palestinian Islamic Jihad in the Palestinian territories, and the Houthi movement in Yemen, as the "Axis of Resistance". These groups receive Iranian support in the form of weapons, funding, and training. According to analyst Afshon Ostovar, the aim of this network is to present Israel with a long-term existential challenge by "slowly strangling" it through a series of "increasingly destructive, unwinnable wars."<ref name=":8">{{Cite book |last=Ostovar |first=Afshon |title=Wars of Ambition: the United States, Iran, and the Struggle for the Middle East |date=2024 |publisher=Oxford University Press |isbn=978-0-19-094098-0 |series= |location=New York, NY |pages=8 |quote=Fifth, the Islamic Republic of Iran’s campaign against Israel is the single most destabilizing conflict in the Middle East, and the one with the greatest potential to cause a broader regional war. The goal of constructing an existential challenge to the State of Israel is the driving motivation behind Iran’s involvement in Lebanon, Syria, Gaza, and the West Bank, and also figures prominently in its support to clients in Iraq and Yemen. Iran has aimed to slowly strangle Israel by keeping it mired in a series of increasingly destructive, unwinnable wars through funneling advanced weaponry and financial backing to groups such as Hezbollah, Hamas, and Palestinian Islamic Jihad. That aggression has compelled Israel to pursue a retaliatory campaign. Because of the wide geography where the Iranian–Israeli conflict has played out, and because of the United States’ deep commitments to Israel and correspondingly hostile relations with Iran, an outbreak of open war between Iran and Israel could encompass much of the region and draw in U.S. involvement.}}</ref>

=== Holocaust denial ===
Until recently, Iran was the only state whose leadership and institutions openly engaged in [[Holocaust denial]] (and at times justification) as part of official ideology.<ref name=":03"/> This rhetoric served to legitimize calls for the destruction of Israel by denying or minimizing the Holocaust, thereby undermining the historical justification for the state's existence and portraying it instead as a product of Western imperialism.<ref name=":032">{{Citation |last=Litvak |first=Meir |title=Iranian Antisemitism and the Holocaust |date=2017 |work=Antisemitism Before and Since the Holocaust: Altered Contexts and Recent Perspectives |pages=205 |editor-last=McElligott |editor-first=Anthony |url=https://doi.org/10.1007/978-3-319-48866-0_9 |access-date=2025-06-16 |place=Cham |publisher=Springer International Publishing |language=en |doi=10.1007/978-3-319-48866-0_9 |isbn=978-3-319-48866-0 |editor2-last=Herf |editor2-first=Jeffrey}}</ref> [[Mohammad-Ali Ramin]], a close advisor to Mahmoud Ahmadinejad, once stated that "the resolution" of the Holocaust issue would lead to the "destruction of Israel."<ref name=":032" />

Iranian media, including outlets aligned with the reformist faction, have accused Israeli intelligence of making efforts to undermine Shi'ite religious rituals and sow sectarian discord.''<ref name=":5">{{Cite book |last=Magen |first=Ze'ev |title=Reading revolutionary Iran: the worldview of the Islamic republic's religio-political elite |date=2023 |publisher=De Gruyter |isbn=978-3-11-101810-2 |series=Studies on Modern Orient |location=Berlin, Boston |pages=625}}</ref>'' In one 2019 example, [[Mossad]] was alleged to have trained Israeli Jews as ''maddahan'' (ritual eulogists) to infiltrate mourning assemblies in Iran and deliberately mislead audiences into cursing or blaspheming.''<ref name=":5" />''
Between 2011 and 2021, Iranian institutions organized dozens of ideologically driven conferences with provocative titles such as ''"Zionism and the [[SARS]] Disease"'', ''"[[Rwandan genocide|Genocide in Rwanda]] and in [[Palestinian genocide accusation|Gaza]]"'' (where only one speaker addressed Rwanda and the remaining fifteen focused on Gaza), and ''"Judaism and [[Hollywood, Los Angeles|Hollywood]]: A Diabolical Conspiracy"'', showing the regime's effort to link Zionism with global ills.''<ref name=":7">{{Cite book |last=Magen |first=Ze'ev |title=Reading revolutionary Iran: the worldview of the Islamic republic's religio-political elite |date=2023 |publisher=De Gruyter |isbn=978-3-11-101810-2 |series=Studies on Modern Orient |location=Berlin, Boston |pages=207–208}}</ref>'' These events, while often poorly attended, are publicly portrayed as major intellectual gatherings, with state media describing a half-empty auditorium as "standing room only" at a conference titled ''"The Jewish Roots of [[MI6|MI-6]]."<ref name=":7" />''

===Academic===
[[Efraim Karsh]], a British–Israeli historian of Middle Eastern politics, has described Iran's posture toward Israel as [[Genocide|genocidal]].<ref name=":0" /> According to American scholar Afshon Ostovar, Iran's campaign against Israel constitutes "the single most destabilizing conflict in the Middle East" and carries "the greatest potential to cause a broader regional war."<ref name=":8" /> American journalist [[Jeffrey Goldberg]] suggests that if Iran acquired nuclear weapons, it would likely intensify its efforts to destroy Israel.<ref name=":9">{{Cite web |last=Goldberg |first=Jeffrey |date=2015-03-09 |title=The Iranian Regime on Israel's Right to Exist |url=https://www.theatlantic.com/international/archive/2015/03/Iranian-View-of-Israel/387085/ |access-date=2025-06-05 |website=The Atlantic |language=en}}</ref>
[[File:Islamic_Republic_of_Iran_Army_Day_2016_(189).jpg|thumb|The words "Death to Israel" in Persian displayed on a parade celebrating Army Day, 2016]]
According to Ze'ev Magen, ''[[Death to Israel]]'' (''marg bar Esra'il''), along with ''[[Death to America]]'', has been a commonly used slogan by Iranian officials for over a quarter of a century.<ref name=":2" /> Magen suggests the call for the conquest of Jerusalem is portrayed as a unifying ''[[jihad]]'' that could redirect Sunni opposition away from Shi'ite Iran, which positions Iran as the vanguard of global Islamic resistance.<ref name=":4"/>
=== Hardliner support within Iran ===
According to [[Mehdi Khalaji]], a new generation of Iranian hardliners, closely tied to the Supreme Leader and the IRGC, has embraced the regime's doctrines, with many believing that Iran is a rising power, the United States is in decline, and that "Israel’s days are numbered."<ref name=":11" />
=== Opposition within Iran ===
[[Sadegh Zibakalam]], an emeritus professor of political science at the [[University of Tehran]], has frequently spoken out against the regime's aggressive policies. He says that the Iranian public, especially the younger generation, is losing interest in the Palestinian issue and even expressing support for figures like Benjamin Netanyahu and Donald Trump. This support does not stem from alignment with their policies, but rather from opposition to the Iranian regime and its backing of groups such as Hamas and Hezbollah. Due to his statements, Zibakalam served an 18-month prison sentence and as of March 2025 was under investigation again, potentially facing further imprisonment.<ref>{{Cite web |last=Azizi |first=Arash |date=2025-03-12 |title=The Iranian Dissident Asking Simple Questions |url=https://www.theatlantic.com/international/archive/2025/03/iran-protest-zibakalam-palestine/682006/ |access-date=2025-06-05 |website=The Atlantic |language=en}}</ref> [[Abdollah Nouri]], a prominent cleric and former interior minister, was sentenced to five years in prison in 1999 (making him the most senior Islamic Republic official to be jailed since the revolution) reportedly for, among other charges, openly challenging Khomeini's doctrine that Israel must be obliterated.<ref>{{Cite book |last=Arjomand |first=Said Amir |title=After Khomeini: Iran under his successors |publisher=Oxford University Press |year=2009 |isbn=978-0-19-539179-4 |location=Oxford ; New York |pages=95–96}}</ref>
=== Jewish religious responses ===
Following the 1979 [[Iranian Revolution]], Jewish religious leaders voiced concern over the potential implications of the new Islamic Republic's policies for Israel and Jewish communities in the region. [[Rabbi Menachem Mendel Schneerson]], known as the [[Lubavitcher Rebbe]], described the revolution as a significant turning point in global politics. In public addresses at the time, he warned that Iran's challenge to the [[United States]] would weaken American influence and embolden hostility toward [[Israel]]. The Rebbe also expressed alarm for the safety of the Jewish community in Iran, which then numbered approximately 50,000, and advocated for a communal day of fasting and prayer in response to the escalating crisis.<ref>{{cite web |last=Shamir |first=Shlomo |title=The Israeli Journalist, Iran, and the Rebbe's Vision |url=https://www.chabad.org/therebbe/article_cdo/aid/2608163/jewish/The-Israeli-Journalist-Iran-and-the-Rebbes-Vision.htm |access-date=2025-06-05 |website=Chabad.org}}</ref>

Since then, this stance has been embedded in official rhetoric, military programs, state-sponsored education, and symbolic events such as [[w:Quds Day|Quds Day]].
The rejection of Israel's legitimacy has remained consistent across both hardline and moderate Iranian leaderships. Supreme Leaders Ruhollah Khomeini and [[w:Ali Khamenei|Ali Khamenei]] have both repeatedly referred to Israel as a "[[Cancer|cancerous]] [[Neoplasm|tumor]]" and publicly called for its elimination. Even reformist leaders and moderate clerics have supported this stance. While the Iranian regime maintains that its opposition is directed at [[Zionism]] rather than at [[Jews]] or [[Judaism]], official propaganda has frequently blurred this distinction, at times incorporating [[Holocaust denial]] and invoking [[w:Antisemitic trope|antisemitic tropes]].
Iran’s anti-Israel policy is implemented through a centralized institutional framework led by the office of the Supreme Leader and the [[w:Islamic Revolutionary Guard Corps|Islamic Revolutionary Guard Corps]] (IRGC). Operational activities are largely carried out via a network of allied non-state actors, including [[w:Hezbollah|Hezbollah]] in [[w:Lebanon|Lebanon]], the [[w:Houthis|Houthis]] in [[w:Yemen|Yemen]], [[w:Hamas|Hamas]] and [[w:Palestinian Islamic Jihad|Palestinian Islamic Jihad]] in the [[Palestinian territories]], and other affiliated groups. These organizations receive sustained Iranian support in the form of funding, weapons, and training, and are collectively referred to by Iranian officials as the "[[w:Axis of Resistance|Axis of Resistance]]." This proxy network enables Iran to exert influence across multiple fronts while posing an existential threat to Israel through asymmetric conflict. Additionally, statements by senior officials and the regime's hostility toward Israel have led many observers{{which|date=June 2025}} to view [[w:Nuclear program of Iran|Iran's nuclear ambitions]] as part of a broader strategy to destroy Israel.

Iran has aimed to slowly strangle Israel by keeping it mired in a series of increasingly destructive, unwinnable wars through funneling advanced weaponry and financial backing to groups such as Hezbollah, Hamas, and Palestinian Islamic Jihad. That aggression has compelled Israel to pursue a retaliatory campaign.

=== Holocaust denial ===
Until recently, Iran was the only state whose leadership and institutions openly engaged in [[Holocaust denial]] (and at times justification) as part of official ideology.<ref name=":03"/> This rhetoric served to legitimize calls for the destruction of Israel by denying or minimizing the Holocaust, thereby undermining the historical justification for the state's existence and portraying it instead as a product of Western imperialism.<ref name=":032">{{Citation |last=Litvak |first=Meir |title=Iranian Antisemitism and the Holocaust |date=2017 |work=Antisemitism Before and Since the Holocaust: Altered Contexts and Recent Perspectives |pages=205 |editor-last=McElligott |editor-first=Anthony |url=https://doi.org/10.1007/978-3-319-48866-0_9 |access-date=2025-06-16 |place=Cham |publisher=Springer International Publishing |language=en |doi=10.1007/978-3-319-48866-0_9 |isbn=978-3-319-48866-0 |editor2-last=Herf |editor2-first=Jeffrey}}</ref> [[Mohammad-Ali Ramin]], a close advisor to Mahmoud Ahmadinejad, once stated that "the resolution" of the Holocaust issue would lead to the "destruction of Israel."<ref name=":032" />

Iranian media, including outlets aligned with the reformist faction, have accused Israeli intelligence of making efforts to undermine Shi'ite religious rituals and sow sectarian discord.''<ref name=":5">{{Cite book |last=Magen |first=Ze'ev |title=Reading revolutionary Iran: the worldview of the Islamic republic's religio-political elite |date=2023 |publisher=De Gruyter |isbn=978-3-11-101810-2 |series=Studies on Modern Orient |location=Berlin, Boston |pages=625}}</ref>'' In one 2019 example, [[Mossad]] was alleged to have trained Israeli Jews as ''maddahan'' (ritual eulogists) to infiltrate mourning assemblies in Iran and deliberately mislead audiences into cursing or blaspheming.''<ref name=":5" />''
Between 2011 and 2021, Iranian institutions organized dozens of ideologically driven conferences with provocative titles such as ''"Zionism and the [[SARS]] Disease"'', ''"[[Rwandan genocide|Genocide in Rwanda]] and in [[Palestinian genocide accusation|Gaza]]"'' (where only one speaker addressed Rwanda and the remaining fifteen focused on Gaza), and ''"Judaism and [[Hollywood, Los Angeles|Hollywood]]: A Diabolical Conspiracy"'', showing the regime's effort to link Zionism with global ills.''<ref name=":7">{{Cite book |last=Magen |first=Ze'ev |title=Reading revolutionary Iran: the worldview of the Islamic republic's religio-political elite |date=2023 |publisher=De Gruyter |isbn=978-3-11-101810-2 |series=Studies on Modern Orient |location=Berlin, Boston |pages=207–208}}</ref>'' These events, while often poorly attended, are publicly portrayed as major intellectual gatherings, with state media describing a half-empty auditorium as "standing room only" at a conference titled ''"The Jewish Roots of [[MI6|MI-6]]."<ref name=":7" />''

===Academic===
[[Efraim Karsh]], a British–Israeli historian of Middle Eastern politics, has described Iran's posture toward Israel as [[Genocide|genocidal]].<ref name=":0" /> According to American scholar Afshon Ostovar, Iran's campaign against Israel constitutes "the single most destabilizing conflict in the Middle East" and carries "the greatest potential to cause a broader regional war."<ref name=":8" /> American journalist [[Jeffrey Goldberg]] suggests that if Iran acquired nuclear weapons, it would likely intensify its efforts to destroy Israel.<ref name=":9">{{Cite web |last=Goldberg |first=Jeffrey |date=2015-03-09 |title=The Iranian Regime on Israel's Right to Exist |url=https://www.theatlantic.com/international/archive/2015/03/Iranian-View-of-Israel/387085/ |access-date=2025-06-05 |website=The Atlantic |language=en}}</ref>
[[File:Islamic_Republic_of_Iran_Army_Day_2016_(189).jpg|thumb|The words "Death to Israel" in Persian displayed on a parade celebrating Army Day, 2016]]
According to Ze'ev Magen, ''[[Death to Israel]]'' (''marg bar Esra'il''), along with ''[[Death to America]]'', has been a commonly used slogan by Iranian officials for over a quarter of a century.<ref name=":2" /> Magen suggests the call for the conquest of Jerusalem is portrayed as a unifying ''[[jihad]]'' that could redirect Sunni opposition away from Shi'ite Iran, which positions Iran as the vanguard of global Islamic resistance.<ref name=":4"/>
=== Hardliner support within Iran ===
According to [[Mehdi Khalaji]], a new generation of Iranian hardliners, closely tied to the Supreme Leader and the IRGC, has embraced the regime's doctrines, with many believing that Iran is a rising power, the United States is in decline, and that "Israel’s days are numbered."<ref name=":11" />
=== Opposition within Iran ===
[[Sadegh Zibakalam]], an emeritus professor of political science at the [[University of Tehran]], has frequently spoken out against the regime's aggressive policies. He says that the Iranian public, especially the younger generation, is losing interest in the Palestinian issue and even expressing support for figures like Benjamin Netanyahu and Donald Trump. This support does not stem from alignment with their policies, but rather from opposition to the Iranian regime and its backing of groups such as Hamas and Hezbollah. Due to his statements, Zibakalam served an 18-month prison sentence and as of March 2025 was under investigation again, potentially facing further imprisonment.<ref>{{Cite web |last=Azizi |first=Arash |date=2025-03-12 |title=The Iranian Dissident Asking Simple Questions |url=https://www.theatlantic.com/international/archive/2025/03/iran-protest-zibakalam-palestine/682006/ |access-date=2025-06-05 |website=The Atlantic |language=en}}</ref> [[Abdollah Nouri]], a prominent cleric and former interior minister, was sentenced to five years in prison in 1999 (making him the most senior Islamic Republic official to be jailed since the revolution) reportedly for, among other charges, openly challenging Khomeini's doctrine that Israel must be obliterated.<ref>{{Cite book |last=Arjomand |first=Said Amir |title=After Khomeini: Iran under his successors |publisher=Oxford University Press |year=2009 |isbn=978-0-19-539179-4 |location=Oxford ; New York |pages=95–96}}</ref>
=== Jewish religious responses ===
Following the 1979 [[Iranian Revolution]], Jewish religious leaders voiced concern over the potential implications of the new Islamic Republic's policies for Israel and Jewish communities in the region. [[Rabbi Menachem Mendel Schneerson]], known as the [[Lubavitcher Rebbe]], described the revolution as a significant turning point in global politics. In public addresses at the time, he warned that Iran's challenge to the [[United States]] would weaken American influence and embolden hostility toward [[Israel]]. The Rebbe also expressed alarm for the safety of the Jewish community in Iran, which then numbered approximately 50,000, and advocated for a communal day of fasting and prayer in response to the escalating crisis.<ref>{{cite web |last=Shamir |first=Shlomo |title=The Israeli Journalist, Iran, and the Rebbe's Vision |url=https://www.chabad.org/therebbe/article_cdo/aid/2608163/jewish/The-Israeli-Journalist-Iran-and-the-Rebbes-Vision.htm |access-date=2025-06-05 |website=Chabad.org}}</ref>

== Spun out from [[w:Iran-Israel relations]] ==
Copied from [[w:Iran-Israel relations]] after another article was merged into it: [[w:Destruction of Israel in Iranian Policy]] after a deletion discussion.
As the "relations" article is very large already, I'm re-creating section on the Islamic republic's destruction policy, as a [[w:WP:SPINOUT]]. It can be analyzed more thoroughly here, as [[Wikiversity:Original research]] is permitted here.
There are many "government policy" articles on Wikipedia. For example America's [[w:Wet feet, dry feet policy]],
or China's [[w:One-child policy]]. So accusations of POV fork made in the deletion discussion, were and are unfounded. There are many forks or spinouts of this policy type. This content area has an article on a ''proposed'' policy of [[w:Proposed Israeli annexation of the West Bank]].
If the article gets merged somewhere, it should have been into an #In_Iranian_policy section of the [[w:Death to Israel]], with that article's content divided on the basis of Country.

'''Cognitive Drive Architecture (CDA)''' is a proposed '''structural field''' within [[cognitive psychology]] that investigates the internal system configurations that enable, sustain, or inhibit cognitive effort. Unlike traditional models that emphasize motivational intention, emotional state, or behavioral output, CDA focuses on the '''structural conditions''' necessary for Drive to emerge at all.
CDA does not explain '''why''' individuals value certain goals or '''how''' they perform tasks once engaged. Instead, it addresses a more foundational layer of inquiry: '''what internal alignments must be present for goal-directed effort to begin, persist, or destabilize in real time.'''
The '''core theory''' that defines and operationalizes CDA is '''Lagunian Dynamics''', a first-principles structural model that formalizes Drive as an emergent property of six internal variables, distributed across three functional domains. These variables belong to Lagunian Dynamics specifically and are used to '''define CDA’s field-level scope''' by differentiating it from trait-based or content-driven psychological theories.
This course introduces CDA as a field through the lens of Lagunian Dynamics, detailing its variables, domain architecture, the Drive Equation, and its empirical and applied implications.

==Learning Objectives==
This course is designed to help learners:
* Understand the '''scope and structural identity''' of Cognitive Drive Architecture as a distinct field in cognitive psychology.
* Explain how '''Lagunian Dynamics''' defines the internal architecture of effort within the CDA field.
* Describe the '''six structural variables''' (Primode, CAP, Flexion, Anchory, Grain, Slip) introduced by Lagunian Dynamics.
* Interpret the functional roles of the '''Ignition''', '''Tension''', and '''Flux''' domains in shaping Drive.
* Analyze the structure and implications of the '''Drive Equation'''.
* Identify common effort breakdowns as patterns of '''variable misconfiguration'''.
* Apply CDA-informed reasoning to '''educational, clinical, technological, and performance contexts'''.

==1.1. Background and Rationale==
'''Cognitive Drive Architecture (CDA)''' emerges as a proposed '''structural field''' in cognitive psychology, responding to a persistent empirical puzzle: '''individuals frequently fail to engage in tasks despite having clear goals, sufficient understanding, and meaningful emotional investment.''' This breakdown is observed across education, therapy, performance, and creative domains.
Traditional models of motivation, executive function, and behavioral decision-making offer partial explanations but do not formally model the '''structural preconditions''' required for Drive to occur in real time. CDA addresses this gap by reframing effort not as a consequence of willpower, value, or skill, but as the emergent result of a cognitive system’s '''internal configuration'''.
CDA positions itself as a '''host field''' that models effort '''beneath''' motivation and executive control, emphasizing the structural alignment of system variables that must be present for action to begin and persist. These internal dynamics are not defined within CDA itself but are made explicit through its '''core theoretical foundation: Lagunian Dynamics'''.
==1.2. Distinction from Adjacent Frameworks==
CDA operates at a distinct level of analysis from conventional psychological models. It does not compete with them but provides the '''structural substrate''' in which they function or fail to. The table below outlines this relationship:
{| class="wikitable"
|+ Comparative positioning of Cognitive Drive Architecture (CDA) relative to major psychological frameworks.
|-
! Framework !! Focus of Explanation !! CDA Interaction
|-
| Self-Determination Theory || Psychological needs and motivation || May influence CAP, but does not determine system ignition
|-
| Executive Function Models || Control processes: inhibition, working memory || Operate within Lagunian Dynamics' Tension domain
|-
| Behavioral Economics || Preferences, discounting, rational choice || Describe the effects of CDA-aligned or misaligned states
|-
| Cognitive Architectures || Procedural cognition simulation || Assume Drive is active; CDA models its entry conditions
|-
|}
'''CDA does not replace these models'''. Rather, it provides a structural lens to understand whether cognitive effort occurs at all and why engagement may fail even in systems with intact goals, knowledge, and intent.
==1.3. Structural Assumptions==
CDA is defined by the structural relationships formalized in '''Lagunian Dynamics''', the core theory that gives CDA its variable architecture. This theory proposes that Drive is not a scalar function of motivation or attention but a '''dynamic output''' generated by six structural variables operating within a cognitive system.
These variables are:
* '''Primode:''' ignition threshold required to initiate Drive
* '''CAP (Cognitive Activation Potential):''' emotional-volitional “voltage” modulating Primode
* '''Flexion:''' adaptability of the task to the internal structure of the system
* '''Anchory:''' attentional tethering force stabilizing engagement
* '''Grain:''' internal resistance that interrupts or impedes Drive
* '''Slip:''' systemic entropy producing variability in otherwise stable systems
Each variable belongs specifically to '''Lagunian Dynamics''', not to CDA in general. Together, they define the '''mechanics''' of Drive as a system output, not a resource or trait. Their configuration determines whether a system transitions from passive readiness to active engagement and whether that engagement remains stable or collapses.

* '''Anchory:''' attentional tethering force stabilizing engagement
* '''Grain:''' internal resistance that interrupts or impedes Drive
* '''Slip:''' systemic entropy producing variability in otherwise stable systems
Each variable belongs specifically to '''Lagunian Dynamics''', not to CDA in general. Together, they define the '''mechanics''' of Drive as a system output, not a resource or trait. Their configuration determines whether a system transitions from passive readiness to active engagement and whether that engagement remains stable or collapses.

==2.1. Overview==
'''Lagunian Dynamics''' is the '''core theoretical model''' that defines the structural mechanics underlying the field of '''Cognitive Drive Architecture (CDA)'''. It formalizes the internal variable interactions that give rise to Drive, not as a trait or motivational state, but as a '''system-level output''' resulting from structural configuration.
Unlike psychological theories that rely on intention, value, or emotion to explain effort, Lagunian Dynamics treats Drive as an '''emergent phenomenon'''. It arises from the interaction of six defined variables that function within a cognitive system's architecture. These variables are not descriptive of behavior or traits; they are '''modeled structurally''', forming the operational backbone of CDA as a field.
==2.2. Variables and Domains==
Lagunian Dynamics defines six structural variables, distributed across three '''functional domains'''. Each domain captures a distinct '''systemic role''' in cognitive effort, operating '''simultaneously''', not sequentially:
{| class="wikitable"
|+ Domain organization of the field of Cognitive Drive Architecture (CDA), showing the structural grouping of variables and their system-level functions
|-
! Domain !! Variables !! System Function
|-
| Ignition || Primode, CAP || Determines if and when Drive is initiated
|-
| Tension || Flexion, Anchory, Grain || Governs sustained engagement and task stability
|-
| Flux || Example || Introduces system variability and entropy
|}
These domains interact dynamically in real time, shaping whether effort begins, holds, or destabilizes.
==2.3. Functional Definitions of Variables==
All six variables are structurally defined; they refer to internal alignment or misalignment conditions, not personality, mood, or motivation. They are as follows:
* '''Primode:''' The '''ignition threshold''', a binary gate. Without its activation, Drive does not begin. It represents the structural readiness to engage, not desire or intention alone.
* '''CAP (Cognitive Activation Potential):''' A modulator of Primode. It amplifies ignition intensity '''exponentially''' but has no effect if Primode is inactive. CAP reflects affective-volitional energy structurally, not motivational want.
* '''Flexion:''' Describes the degree to which a task can be '''internally reshaped''' to match the current cognitive configuration. High Flexion feels fluid; low Flexion feels structurally rigid, regardless of content difficulty.
* '''Anchory:''' Models '''attentional tethering''', the structural force that stabilizes attention over time. It resists distraction but does not create attention.
* '''Grain:''' Represents internal '''friction or resistance''', such as dissonance, mental drag, or affective tension that interrupts sustained Drive.
* '''Slip:''' Reflects '''system entropy''', internal stochastic variability in performance. It does not signal failure but introduces unpredictability across otherwise consistent configurations.
'''Note:''' These variables are not constructs of CDA generically; they '''belong specifically to Lagunian Dynamics''', which provides CDA its structural identity.
==2.4. Interactions and System Logic==
Lagunian Dynamics treats variable interaction as continuous and conditionally constrained. The following principles define its logic:
* '''Primode must be active''' for CAP to modulate Drive. Without ignition, CAP’s intensity has no impact.
* '''Flexion''' does not initiate Drive but governs whether Drive, once started, sustains or collapses.
* '''Anchory and Grain''' act in tension: one stabilizes task engagement, the other disrupts it. Their balance determines stability.
* '''Slip''' operates '''outside''' the main structural control loop; it adds entropy even in well-aligned systems, accounting for intra-individual variability under identical conditions.
This interactional logic allows the model to simulate not only the onset of action but also the '''instability and decay of engagement'''.
==2.5. Structural Framing==
Lagunian Dynamics is not a metaphor or heuristic. It is a '''first-principles structural system''' defining how internal configurations generate or fail to generate Drive. It rests on three central propositions:
* '''Drive is a system output''', not a trait, state, or resource.
* '''Motivation, attention, and emotion''' are modulators or correlates, but not sufficient causes of Drive.
* '''Failure to act''' is often the result of '''misconfiguration''', not laziness, lack of will, or incapacity.
This model reframes effort breakdowns such as procrastination, burnout, or inconsistency not as flaws in personality but as '''structurally explainable system states''', measurable, interpretable, and potentially modifiable.

==3.1. Introduction to the Ignition Domain==
The '''Ignition Domain''', as defined by '''Lagunian Dynamics''', models the structural preconditions necessary for '''Drive to begin'''. It does not explain goal value or task appeal; these belong to motivational or evaluative theories. Instead, this domain asks: '''What must be structurally present for intention to transition into action?'''
Two variables operate within this domain:
* '''Primode:''' the ignition threshold variable
* '''CAP (Cognitive Activation Potential):''' an affective-volitional voltage amplifier
These variables work in tandem to determine whether a cognitive task is entered at all. Without their coordinated presence, effort does not begin, no matter how valuable, urgent, or emotionally charged the goal appears.
==3.2. Primode: The Structural Ignition Threshold==
'''Primode''' is a '''binary structural variable''' that determines whether the system transitions from passive readiness to active engagement. It is not influenced by personality, motivation level, or willpower; it functions like a circuit switch: '''either on or off'''.
'''Key Characteristics:'''
* Not a trait or scalar motivation level.
* Ignition occurs only when attentional focus and intent structurally align.
* No amount of external incentive or inner desire will initiate action if Primode remains inactive.
'''Conceptual Distinctions:'''
* '''Implementation intentions''' (Gollwitzer, 1999) scaffold behavior but do not model ignition.
* '''Executive gatekeeping''' (Chatham & Badre, 2015) controls information flow, not engagement onset.
In Lagunian Dynamics, '''Primode is necessary but not sufficient for Drive'''. It opens the gate, but acceleration depends on downstream structural factors, primarily CAP.
==3.3. CAP: Cognitive Activation Potential==
'''CAP''' is a '''volitional-affective amplifier''' that modulates the ignition system once Primode is structurally active. It is not a measure of desire or motivation, but of the system’s '''energetic readiness''' to transition into action.
'''Key Characteristics:'''
* Modeled as an '''exponential voltage amplifier''', not a linear force.
* Has '''no impact if Primode = 0'''; it only modulates, not initiates.
* When active, even moderate CAP can '''cause rapid Drive acceleration'''.
'''Related Constructs (but not equivalent):'''
* '''Motivational intensity theory''' (Brehm & Self, 1989)
* '''Urgency-based engagement''' (Kuhl, 1985; Silvia, 2006)
CAP does not measure whether someone wants to act; it models whether that desire translates into '''usable system energy''' under ignition-ready conditions. This distinction allows Lagunian Dynamics to structurally explain “motivated inaction.”
==3.4. Interaction Between Primode and CAP==
The interaction between Primode and CAP is '''nonlinear and asymmetric''', forming the foundation of the '''Drive Equation''' within Lagunian Dynamics:
'''Interaction Logic:'''
* If '''Primode = 0''', the entire numerator of the Drive Equation collapses to zero; '''CAP has no effect'''.
* If '''CAP = 0, but Primode = 1''', the Drive signal defaults to '''neutral''': Primode<sup>0</sup> = 1
* When '''both are active''', Drive '''escalates rapidly''' due to CAP’s exponential modulation.
'''Examples from Real Systems:'''
* '''High urgency, no action:''' CAP↑ but Primode = 0 → system remains inert.
* '''Delayed starts:''' ignition fails until CAP rises above a functional threshold.
* '''Emotional strain without action:''' high CAP trapped beneath inactive Primode causes agitation or burnout.
==3.5. Examples of Ignition Domain Failures==
{| class="wikitable"
|+ Drive system configurations in the Ignition domain.
|-
! Configuration !! Observed Behavior !! Structural Explanation
|-
| Primode = 0, CAP = moderate || Intent exists, but task never begins || Ignition gate not structurally open
|-
| Primode = 1, CAP = low || Task begins slowly, weak engagement || Drive initiated, but minimal activation energy
|-
| Primode = 0, CAP = high || Frustration or emotional overload || Energy builds with no ignition pathway
|}
These are not motivational failures or psychological flaws; '''they are configuration states'''. Lagunian Dynamics allows such states to be identified and modeled independently of intention, personality, or external pressure.
==3.6. Empirical Implications==
The structural modeling of the Ignition Domain yields testable predictions for researchers and practitioners:
* '''Time-to-Initiation (TTI)''' should not correlate directly with self-reported motivation.
* '''Primode''' may be inferred through '''readiness potentials''' (e.g., EEG) or '''motor priming latency'''.
* '''CAP''' may be approximated using physiological proxies:
** Skin conductance response (SCR)
** Facial microexpression patterns
** Pupil dilation under task-trigger cues
These predictions create pathways for real-time measurement and experimental validation, forming the empirical basis for later modules in the course.

The Tension Domain (Flexion, Anchory, and Grain) page has been created.
2719681
wikitext
text/x-wiki
==4.1. Overview==
The '''Tension Domain''', as defined in '''Lagunian Dynamics''', governs the '''stability and sustainability''' of Drive once cognitive effort has been initiated. While the Ignition Domain models whether Drive begins, the Tension Domain determines whether that effort can be maintained or whether it will fragment, stall, or decay under structural strain.
This domain is composed of three interacting structural variables:
* '''Flexion:''' adaptability of the task to the cognitive system
* '''Anchory:''' attentional tethering force
* '''Grain:''' internal resistance and systemic friction
These variables do not measure emotional states or task difficulty. Instead, they define whether the '''alignment between system and task''' remains coherent across time. Their interplay models the '''mechanical stability''' of Drive.
==4.2. Flexion: Structural Adaptability==
'''Flexion''' represents the degree to which a task can be internally reshaped to match the system’s real-time cognitive structure. It is not a measure of difficulty or flow state but of '''task malleability''', how workable the task feels moment to moment.
'''Key Characteristics:'''
* '''High Flexion''' → The task conforms easily to the user’s cognitive state; engagement flows.
* '''Low Flexion''' → The task feels rigid or incompatible, even if conceptually understood.
'''Important Distinctions:'''
* '''Flexion ≠ fluency:''' it's not about ease of processing, but adaptability to internal form.
* '''Flexion ≠ flow:''' it does not imply enjoyment, only structural fit.
'''Related Constructs:'''
* '''Cognitive fluency''' (Alter & Oppenheimer, 2009)
* '''Task affordances''' (Norman, 1988)
* '''Mental model alignment''' (Johnson-Laird, 1983)
Flexion is central to understanding why some tasks, despite being familiar or valued, still feel unworkable, a structural, not motivational, misfit.
==4.3. Anchory: Attentional Tethering==
'''Anchory''' models the force that '''binds attention''' to the task environment. It does not generate attention but stabilizes it against drift and distraction. Anchory determines whether focus can hold once initiated.
==Key Characteristics:==
* '''High Anchory''' → Attention remains stable over time despite minor interruptions.
* '''Low Anchory''' → Focus fragments easily, even under minimal friction.
Anchory is dynamic; it can degrade with rising Grain or under sustained entropy (Slip).
'''Related Constructs:'''
* '''Sustained attention''' (Posner & Petersen, 1990)
* '''Executive attentional control''' (Kane & Engle, 2003)
'''Anchory is not capacity-based'''; it's a structural tether. A person may have attention but lack the stability to maintain it under strain.
==4.4. Grain: Internal Resistance==
'''Grain models the frictional forces''' that disrupt sustained effort. These forces can be cognitive (e.g., overload, dissonance) or emotional (e.g., boredom, tension). Grain does not represent emotional states, but the '''structural drag''' they exert on task engagement.
'''Key Characteristics:'''
* '''High Grain''' → task feels abrasive; effort is costly and unstable.
* '''Low Grain''' → engagement feels smooth; resistance is minimal.
'''Related Constructs:'''
* '''Affective resistance''' (Inzlicht et al., 2015)
* '''Intrinsic task aversion'''
* '''Cognitive load''' (Sweller, 1988)
Grain is not a mood or feeling, it's a disruptive force that destabilizes Anchory and limits usable Flexion.
==4.5. Structural Interactions Within the Tension Domain==
The Tension Domain is best understood through interactional balance:
{| class="wikitable"
|+ Tension domain variables in Cognitive Drive Architecture (CDA).
|-
! Variable !! Structural Role !! Effect on Engagement
|-
| Flexion || Task-to-mind adaptability || Increases fluidity, reduces structural tension
|-
| Anchory || Focus stabilization || Maintains attention over time
|-
| Grain || Internal resistance || Disrupts focus, accelerates disengagement
|}
'''Key interactions:'''
* '''Flexion''' supports adaptability; the system reshapes the task to its internal state.
* '''Anchory''' maintains tethering but can fail if Grain rises too fast.
* '''Grain''' introduces destabilization, eroding both Anchory and perceived Flexion.
Drive collapse often results from this triadic imbalance, not from willpower failure, but from structural misalignment.
==4.6. Examples of Tension Domain Failure Patterns==
{| class="wikitable"
|+ Structural failure configurations in the Tension domain of CDA.
|-
! Configuration !! Observed Outcome !! Interpretation
|-
| Flexion ↓, Grain ↑ || Rapid disengagement after initial effort || Task misfit causes overload and retreat
|-
| Anchory ↓, Grain ↑ || Gradual fragmentation of focus || Tether weakens under affective friction
|-
| Anchory ↑, Flexion ↓ || "Busy work" without progress || Focus is present, but engagement is non-adaptive
|}
These breakdowns are often misattributed to laziness or distraction. Lagunian Dynamics reinterprets them as '''configuration failures''', traceable to real-time structural variables.
==4.7. Empirical Considerations==
Each Tension Domain variable is open to empirical modeling and measurement:
* '''Flexion:'''
** Self-reported task–mind fit
** Cursor movement smoothness
** Problem-solving fluency patterns
* '''Anchory:'''
** Eye-tracking fixation duration
** Blink frequency
** Attentional drift markers
* '''Grain:'''
** Subjective resistance or friction scales
** Heart rate variability (HRV) under load
** Facial micro-EMG (e.g., brow tension)
These measures offer a path toward validating the '''structural mechanics of Drive''' in dynamic, real-world tasks, a key aim of CDA as a field defined by '''Lagunian Dynamics'''.

==4.2. Flexion: Structural Adaptability==
'''Flexion''' represents the degree to which a task can be internally reshaped to match the system’s real-time cognitive structure. It is not a measure of difficulty or flow state but of '''task malleability''', how workable the task feels moment to moment.
'''Key Characteristics:'''
* '''High Flexion''' → The task conforms easily to the user’s cognitive state; engagement flows.
* '''Low Flexion''' → The task feels rigid or incompatible, even if conceptually understood.
'''Important Distinctions:'''
* '''Flexion ≠ fluency:''' it's not about ease of processing, but adaptability to internal form.
* '''Flexion ≠ flow:''' it does not imply enjoyment, only structural fit.
'''Related Constructs:'''
* '''Cognitive fluency''' (Alter & Oppenheimer, 2009)
* '''Task affordances''' (Norman, 1988)
* '''Mental model alignment''' (Johnson-Laird, 1983)
Flexion is central to understanding why some tasks, despite being familiar or valued, still feel unworkable, a structural, not motivational, misfit.
==4.3. Anchory: Attentional Tethering==
'''Anchory''' models the force that '''binds attention''' to the task environment. It does not generate attention but stabilizes it against drift and distraction. Anchory determines whether focus can hold once initiated.
==Key Characteristics:==
* '''High Anchory''' → Attention remains stable over time despite minor interruptions.
* '''Low Anchory''' → Focus fragments easily, even under minimal friction.
Anchory is dynamic; it can degrade with rising Grain or under sustained entropy (Slip).
'''Related Constructs:'''
* '''Sustained attention''' (Posner & Petersen, 1990)
* '''Executive attentional control''' (Kane & Engle, 2003)
'''Anchory is not capacity-based'''; it's a structural tether. A person may have attention but lack the stability to maintain it under strain.
==4.4. Grain: Internal Resistance==
'''Grain models the frictional forces''' that disrupt sustained effort. These forces can be cognitive (e.g., overload, dissonance) or emotional (e.g., boredom, tension). Grain does not represent emotional states, but the '''structural drag''' they exert on task engagement.
'''Key Characteristics:'''
* '''High Grain''' → task feels abrasive; effort is costly and unstable.
* '''Low Grain''' → engagement feels smooth; resistance is minimal.
'''Related Constructs:'''
* '''Affective resistance''' (Inzlicht et al., 2015)
* '''Intrinsic task aversion'''
* '''Cognitive load''' (Sweller, 1988)
Grain is not a mood or feeling, it's a disruptive force that destabilizes Anchory and limits usable Flexion.
==4.5. Structural Interactions Within the Tension Domain==
The Tension Domain is best understood through interactional balance:
{| class="wikitable"
|+ Tension domain variables in Cognitive Drive Architecture (CDA).
|-
! Variable !! Structural Role !! Effect on Engagement
|-
| Flexion || Task-to-mind adaptability || Increases fluidity, reduces structural tension
|-
| Anchory || Focus stabilization || Maintains attention over time
|-
| Grain || Internal resistance || Disrupts focus, accelerates disengagement
|}
'''Key interactions:'''
* '''Flexion''' supports adaptability; the system reshapes the task to its internal state.
* '''Anchory''' maintains tethering but can fail if Grain rises too fast.
* '''Grain''' introduces destabilization, eroding both Anchory and perceived Flexion.
Drive collapse often results from this triadic imbalance, not from willpower failure, but from structural misalignment.
==4.6. Examples of Tension Domain Failure Patterns==
{| class="wikitable"
|+ Structural failure configurations in the Tension domain of CDA.
|-
! Configuration !! Observed Outcome !! Interpretation
|-
| Flexion ↓, Grain ↑ || Rapid disengagement after initial effort || Task misfit causes overload and retreat
|-
| Anchory ↓, Grain ↑ || Gradual fragmentation of focus || Tether weakens under affective friction
|-
| Anchory ↑, Flexion ↓ || "Busy work" without progress || Focus is present, but engagement is non-adaptive
|}
These breakdowns are often misattributed to laziness or distraction. Lagunian Dynamics reinterprets them as '''configuration failures''', traceable to real-time structural variables.
==4.7. Empirical Considerations==
Each Tension Domain variable is open to empirical modeling and measurement:
* '''Flexion:'''
** Self-reported task–mind fit
** Cursor movement smoothness
** Problem-solving fluency patterns
* '''Anchory:'''
** Eye-tracking fixation duration
** Blink frequency
** Attentional drift markers
* '''Grain:'''
** Subjective resistance or friction scales
** Heart rate variability (HRV) under load
** Facial micro-EMG (e.g., brow tension)
These measures offer a path toward validating the '''structural mechanics of Drive''' in dynamic, real-world tasks, a key aim of CDA as a field defined by '''Lagunian Dynamics'''.

==5.1. Overview==
The '''Flux Domain''', as defined by '''Lagunian Dynamics''', models the structural basis for '''endogenous variability''' in cognitive performance. Whereas the Ignition and Tension Domains govern whether Drive begins and whether it sustains, the Flux Domain addresses the '''stability''' of Drive's output over time.
This domain is composed of a '''single variable''':
* '''Slip:''' internal entropy or stochastic variability
Slip doesn't initiate or terminate engagement. Instead, it introduces '''inherent irregularity into performance''', even when all other structural variables are optimally aligned. It accounts for '''intra-individual inconsistency''' that cannot be traced to external context, task difficulty, or motivational fluctuation.
==5.2. Slip: Structural Entropy in Cognitive Performance==
'''Slip''' represents '''baseline entropy''' within the Drive system, a persistent, internally generated variability. It is not conceptualized as dysfunction or failure but as a '''native property''' of dynamic cognitive architecture.
'''Key Characteristics:'''
* Slip is not a bug in the system; it is a '''baseline condition''' of all engagement.
* It reflects '''internal instability''', not loss of motivation or attention.
* High-Slip states may present as erratic performance, sudden disengagement, or unexplained lapses.
* Slip interacts with the Ignition and Tension Domains but remains '''functionally independent''' in the Drive Equation:
<math>Drive=\left ( \frac{P^C\times F}{A+G} \right )+S</math>
where,
P = Primode
C = CAP
F = Flexion
A = Anchory
G= Grain
S= Slip
Unlike other terms, '''Slip is additive'''. It does not amplify or suppress Drive directly; it '''modulates consistency''', not magnitude.
==5.3. Role of Slip in Explaining Performance Variability==
Traditional models often explain behavioral inconsistency as:
* Measurement error
* Temporary distraction
* Mood fluctuation
* Arousal or willpower failure
In contrast, '''Lagunian Dynamics reframes variability as structural entropy'''. Slip accounts for:
* '''Abrupt lapses''' in focus despite high motivation and clear intention
* '''Unpredictable shifts''' in productivity under identical conditions
* '''Emotional residue''' from prior tasks that destabilizes performance without conscious awareness
Slip allows CDA to structurally model what appears as “noise” in other paradigms as a signal.
==5.4. Distinctions and Related Constructs==
While no prior model formalizes Slip as Lagunian Dynamics does, it is conceptually adjacent to:
* '''Mind-wandering''' (Smallwood & Schooler, 2015)
* '''Intra-individual variability in attention or reaction time''' (MacDonald et al., 2006)
* '''Cognitive effort limits in high-load tasks''' (Kahneman, 1973)
'''The critical distinction:'''
* Other models treat variability as interference or error.
* '''Lagunian Dynamics treats Slip as a structural feature''', part of the system’s functional reality.
==5.5. Measurement and Empirical Indicators==
Slip can be approximated through multimodal physiological and behavioral signals, especially when other variables (e.g., CAP, Anchory) are held constant.
{| class="wikitable"
|+ Signal types and modalities for detecting cognitive variability in CDA.
|-
! Signal Type !! Measurement Modality
|-
| Performance drift || Reaction time variance, keystroke irregularity
|-
| Cognitive instability || Pupillometric fluctuation, gaze deviation
|-
| Motor/attention noise || Cursor jitter, blink rate volatility
|}
These proxies help isolate Slip from motivational or contextual effects and provide real-time estimates of '''entropy load''' in the system.
==5.6. Behavioral Examples of High-Slip States==
{| class="wikitable"
|+ CDA interpretations of performance variability under stable conditions.
|-
! Context !! Behavioral Signature !! CDA Interpretation
|-
| Task repetition under stable conditions || Fluctuating focus or accuracy || Slip-induced instability
|-
| Emotional residue from the prior task || Delays or disengagement without cause || Entropic carryover disrupting baseline
|-
| Identical routines, variable output || Inconsistent performance across the same input || Structural noise, not motivational change
|}
'''Slip explains why behavior varies meaningfully even when conditions are held constant''', filling a key explanatory gap in traditional models.
==5.7. Theoretical Function of Slip==
Slip plays several essential roles in the architecture of Lagunian Dynamics:
* Introduces '''non-linearity''' into system behavior.
* Prevents oversimplified, deterministic predictions of Drive.
* Accounts for '''state-dependent volatility''' without reducing explanation to emotion or willpower.
* Validates the '''probabilistic character of cognitive effort''', even under optimal configurations.
By formalizing Slip, Lagunian Dynamics reinforces CDA’s aim as a structural field, capable of modeling not just why Drive begins, but why it fluctuates, even under identical conditions.

==6.1. Overview==
At the core of Lagunian Dynamics, the defining theory of Cognitive Drive Architecture (CDA), lies the Drive Equation, '''a structural formulation that models cognitive Drive as a real-time system output'''. Unlike motivational or personality-based models, the Drive Equation '''quantifies the internal alignment required for effort to emerge, sustain, or destabilize'''.
The equation formalizes the interaction of six structural variables across three domains, Ignition, Tension, and Flux, producing a real-time representation of a system’s capacity for goal-directed engagement.
==6.2. The Equation==
The Drive Equation is expressed as:
<math>Drive=\left ( \frac{P^C\times F}{A+G} \right )+S</math>
where,
P = Primode
C = CAP
F = Flexion
A = Anchory
G= Grain
S= Slip
{| class="wikitable"
|+ CDA variables by role and domain.
|-
! Variable !! Role !! Domain
|-
| Primode || Binary ignition threshold || Ignition
|-
| CAP || Exponential ignition amplifier || Ignition
|-
| Flexion || Task adaptability to internal structure || Tension
|-
| Anchory || Attentional tethering || Tension
|-
| Grain || Internal resistance/friction || Tension
|-
| Slip || Structural entropy/variability || Flux
|}
This is not a measure of motivation, personality, or ability. '''It is a structural expression of whether a system can act and whether its effort will hold or collapse under internal conditions.'''
==6.3. Numerator: Activation and Adaptability==
<math>Drive={P^C\times F}</math>
where,
P = Primode
C = CAP
F = Flexion
* '''Primode is a binary switch (0 or 1)'''; without it, no Drive is possible.
* '''CAP modulates Drive exponentially''' only if Primode is active.
* '''Flexion filters ignition through task adaptability'''; it scales the impact of Primode and CAP.
'''Key Properties:'''
* If Primode = 0, Drive = 0, regardless of CAP or Flexion.
* If CAP = 0, then Primode<sup>0</sup> = 1, yielding baseline output.
* Even high CAP cannot overcome low Flexion; the task must fit the cognitive system structurally.
This part of the equation defines initiation power, how strong Drive is when the system is ready and the task is structurally workable.
==6.4. Denominator: Attentional Stability and Resistance==
<math>Drive={Anchory + Grain}</math>
* Anchory holds attention steady.
* Grain introduces tension that disrupts focus.
These forces counterbalance one another:
* High Anchory stabilizes Drive → smaller denominator → stronger Drive output.
* High Grain destabilizes Drive → larger denominator → weakened output.
This sum models the resilience of Drive once ignition has occurred, whether it remains stable or begins to degrade under internal resistance.
==6.5. Additive Term: Systemic Variability==
<math>Drive={+ Slip}</math>
* '''Slip represents endogenous entropy''', non-deterministic fluctuations in performance.
* '''Slip is additive, not multiplicative''', meaning it modifies expression, not structure.
* Slip explains why the same configuration can yield different behaviors across time.
Slip ensures that even well-aligned systems don’t behave deterministically, allowing the model to reflect real-world cognitive volatility.
==6.6. Functional Implications of the Equation==
This structural formulation enables precise interpretation of common engagement outcomes:
{| class="wikitable"
|+ Drive equation interpretations of common effort patterns.
|-
! Pattern !! Equation-Based Explanation
|-
| High urgency, no action || CAP↑, but Primode = 0 → Drive = 0
|-
| Quick start, fast burnout || Primode = 1, but Anchory ↓, Grain ↑ → Denominator ↑
|-
| Inconsistent output across days || Stable configuration, but Slip ↑ → entropy dominates
|-
| Deep engagement/flow || All aligned: high Primode, CAP, Flexion, Anchory; low Grain, moderate Slip
|}
Rather than attributing these outcomes to personality or mood, the equation models them as structural effects of system configuration.
==6.7. Structural Principles Embedded in the Equation==
The Drive Equation encodes core laws of Lagunian Dynamics:
* '''Initiation is binary:''' No Drive unless Primode = 1.
* '''Intensity is nonlinear:''' CAP affects Drive exponentially, not linearly.
* '''Stability is competitive:''' Anchory vs. Grain determines effort duration.
* '''Performance is probabilistic:''' Slip guarantees variability across trials.
* '''Drive is structural:''' Not a trait, but an emergent system state.
These principles form the basis of CDA as a structural field, capable of diagnosing real-time effort breakdowns and transitions.
==6.8. Conceptual Distinctions==
{| class="wikitable"
|+ Comparison between traditional models and the Drive Equation (CDA).
|-
! Traditional Models !! Drive Equation (CDA)
|-
| Motivation as scalar intensity || Drive as emergent system output
|-
| Engagement as trait or capacity || Engagement as dynamic structural configuration
|-
| Variability as measurement error || Variability as structured entropy (Slip)
|-
| Failure = weak will or low value || Failure = misalignment of internal variables
|}

==6.1. Overview==
At the core of Lagunian Dynamics, the defining theory of Cognitive Drive Architecture (CDA), lies the Drive Equation, '''a structural formulation that models cognitive Drive as a real-time system output'''. Unlike motivational or personality-based models, the Drive Equation '''quantifies the internal alignment required for effort to emerge, sustain, or destabilize'''.
The equation formalizes the interaction of six structural variables across three domains, Ignition, Tension, and Flux, producing a real-time representation of a system’s capacity for goal-directed engagement.
==6.2. The Equation==
The Drive Equation is expressed as:
<math>Drive=\left ( \frac{P^C\times F}{A+G} \right )+S</math>
where,
P = Primode
C = CAP
F = Flexion
A = Anchory
G= Grain
S= Slip
{| class="wikitable"
|+ CDA variables by role and domain.
|-
! Variable !! Role !! Domain
|-
| Primode || Binary ignition threshold || Ignition
|-
| CAP || Exponential ignition amplifier || Ignition
|-
| Flexion || Task adaptability to internal structure || Tension
|-
| Anchory || Attentional tethering || Tension
|-
| Grain || Internal resistance/friction || Tension
|-
| Slip || Structural entropy/variability || Flux
|}
This is not a measure of motivation, personality, or ability. '''It is a structural expression of whether a system can act and whether its effort will hold or collapse under internal conditions.'''
==6.3. Numerator: Activation and Adaptability==
<math>Drive={P^C\times F}</math>
where,
P = Primode
C = CAP
F = Flexion
* '''Primode is a binary switch (0 or 1)'''; without it, no Drive is possible.
* '''CAP modulates Drive exponentially''' only if Primode is active.
* '''Flexion filters ignition through task adaptability'''; it scales the impact of Primode and CAP.
'''Key Properties:'''
* If Primode = 0, Drive = 0, regardless of CAP or Flexion.
* If CAP = 0, then Primode<sup>0</sup> = 1, yielding baseline output.
* Even high CAP cannot overcome low Flexion; the task must fit the cognitive system structurally.
This part of the equation defines initiation power, how strong Drive is when the system is ready and the task is structurally workable.
==6.4. Denominator: Attentional Stability and Resistance==
<math>Drive={Anchory + Grain}</math>
* Anchory holds attention steady.
* Grain introduces tension that disrupts focus.
These forces counterbalance one another:
* High Anchory stabilizes Drive → smaller denominator → stronger Drive output.
* High Grain destabilizes Drive → larger denominator → weakened output.
This sum models the resilience of Drive once ignition has occurred, whether it remains stable or begins to degrade under internal resistance.
==6.5. Additive Term: Systemic Variability==
<math>Drive={+ Slip}</math>
* '''Slip represents endogenous entropy''', non-deterministic fluctuations in performance.
* '''Slip is additive, not multiplicative''', meaning it modifies expression, not structure.
* Slip explains why the same configuration can yield different behaviors across time.
Slip ensures that even well-aligned systems don’t behave deterministically, allowing the model to reflect real-world cognitive volatility.
==6.6. Functional Implications of the Equation==
This structural formulation enables precise interpretation of common engagement outcomes:
{| class="wikitable"
|+ Drive equation interpretations of common effort patterns.
|-
! Pattern !! Equation-Based Explanation
|-
| High urgency, no action || CAP↑, but Primode = 0 → Drive = 0
|-
| Quick start, fast burnout || Primode = 1, but Anchory ↓, Grain ↑ → Denominator ↑
|-
| Inconsistent output across days || Stable configuration, but Slip ↑ → entropy dominates
|-
| Deep engagement/flow || All aligned: high Primode, CAP, Flexion, Anchory; low Grain, moderate Slip
|}
Rather than attributing these outcomes to personality or mood, the equation models them as structural effects of system configuration.
==6.7. Structural Principles Embedded in the Equation==
The Drive Equation encodes core laws of Lagunian Dynamics:
* '''Initiation is binary:''' No Drive unless Primode = 1.
* '''Intensity is nonlinear:''' CAP affects Drive exponentially, not linearly.
* '''Stability is competitive:''' Anchory vs. Grain determines effort duration.
* '''Performance is probabilistic:''' Slip guarantees variability across trials.
* '''Drive is structural:''' Not a trait, but an emergent system state.
These principles form the basis of CDA as a structural field, capable of diagnosing real-time effort breakdowns and transitions.
==6.8. Conceptual Distinctions==
{| class="wikitable"
|+ Comparison between traditional models and the Drive Equation (CDA).
|-
! Traditional Models !! Drive Equation (CDA)
|-
| Motivation as scalar intensity || Drive as emergent system output
|-
| Engagement as trait or capacity || Engagement as dynamic structural configuration
|-
| Variability as measurement error || Variability as structured entropy (Slip)
|-
| Failure = weak will or low value || Failure = misalignment of internal variables
|}
This model reframes the study of effort:

'''To''' “Can my system structurally engage, and for how long?”

==7.1. Overview==
Despite sufficient knowledge, intent, or motivation, individuals often fail to begin or sustain effort. These breakdowns are frequently labeled as procrastination, laziness, or lack of discipline. '''Lagunian Dynamics''', the core theory defining the field of '''Cognitive Drive Architecture (CDA)''', offers a structural explanation: such patterns emerge from identifiable misalignments among internal system variables.
This module introduces '''recurrent failure modes''' and stable Drive-disrupting configurations and shows how each can be modeled through the '''Drive Equation'''.
==7.2. What Is a Structural Failure Mode?==
In CDA, a '''structural failure mode''' refers to a reproducible configuration of system variables that leads to one or more of the following:
* '''Ignition failure:''' Drive never initiates.
* '''Volatility:''' Engagement is erratic or short-lived.
* '''Decay:''' Effort begins but cannot be sustained.
These modes are not pathologies. They are '''functional misalignments''' that can occur in any cognitive system under pressure, overload, or poor fit, regardless of will or ability.
==7.3. Common Structural Failure Modes==
{| class="wikitable"
|+ Common Drive system failure modes in CDA.
|-
! Failure Mode !! Key Configuration !! Behavioral Pattern
|-
| Start Failure || Primode = 0; CAP ↑ || Persistent intent with no task entry
|-
| Motivated Stall || Primode = 1; CAP ↑; Flexion ↓ || High urgency but no productive momentum
|-
| Drift Collapse || Anchory ↓; Grain ↑; Slip ↑ || Starts well, then quickly loses focus
|-
| Overwhelm Spike || CAP ↑↑; Grain ↑↑; Anchory ↓ || Bursts of action followed by shutdown
|-
| Resistance Spiral || Flexion ↓; Grain ↑; repeated misfire || Re-attempts with rising aversion and failure
|-
| Entropy Drag || Stable structure; Slip ↑↑ || Output fluctuates despite stable conditions
|}
Each failure mode has a '''distinct structural fingerprint''', identifiable through the Drive Equation and observable behaviorally.
==7.4. Structural Case Examples==
'''Example A: Start Failure'''
'''Drive Equation:'''
<math>Drive=\left ( \frac{O^C\times F}{A+G} \right )+S=O+S</math>
where,
P = Primode = O
C = CAP
F = Flexion
A = Anchory
G= Grain
S= Slip
'''Interpretation:'''
Despite CAP being elevated (strong urgency or emotional charge), '''Primode = 0''' prevents ignition. Drive output defaults to Slip, variability with no engagement.
'''Example B: Drift Collapse'''
'''Drive Equation:'''
<math>Drive=\left ( \frac{1^C\times F}{A(low) + G(high)} \right )+S(high)</math>
where,
P = Primode = 1
C = CAP
F = Flexion
A = Anchory
G= Grain
S= Slip
'''Interpretation:'''
Initial effort exists (Primode = 1), but low Anchory, high Grain, and elevated Slip destabilize Drive quickly. Engagement begins but rapidly deteriorates.
==7.5. Why Traditional Models Struggle with These Failures==
{| class="wikitable"
|+ CDA reinterpretation of common motivational advice.
|-
! Traditional Response !! Structural CDA Interpretation
|-
| "You need more motivation." || CAP is already high; Primode or Flexion misaligned.
|-
| "Just try harder." || May raise Grain or Slip, worsening the misalignment.
|-
| "Use productivity tools." || May help Flexion, but ineffective if Primode = 0.
|}
Traditional models often conflate '''intention with execution'''. CDA separates the two, offering a system-level explanation that clarifies '''why good intentions often fail structurally'''.
==7.6. Failure Mode Recognition in Practice==
{| class="wikitable"
|+ Observable indicators of Drive failure modes in CDA.
|-
! Mode !! Observable Indicators
|-
| Start Failure || Delays despite urgency, overthinking task entry
|-
| Motivated Stall || Frustration without action, lingering inertia
|-
| Drift Collapse || Focus fades quickly; regaining traction is hard
|-
| Resistance Spiral || Cycles of failure and avoidance
|-
| Entropy Drag || Wildly variable performance across similar days
|}
These patterns are '''domain-independent''' and can emerge in academic, professional, or therapeutic contexts, even in highly skilled individuals.
==7.7. Structural Reconfiguration as Intervention==
CDA suggests remediation through '''targeted structural realignment''', not motivational boosting.
{| class="wikitable"
|+ Intervention strategies for Drive failure modes in CDA.
|-
! Failure Mode !! Potential Intervention Targets
|-
| Start Failure || Scaffold Primode (e.g., micro-goals, ignition cues)
|-
| Motivated Stall || Boost Flexion via task restructuring or reframing
|-
| Drift Collapse || Stabilize Anchory (minimal environment switching)
|-
| Overwhelm Spike || Reduce CAP (pressure) and Grain (emotional resistance)
|-
| Resistance Spiral || Introduce high-Flexion tasks to reset system
|-
| Entropy Drag || Use temporal anchors (e.g., rhythmic time blocks)
|}
These shifts can restore Drive without altering personality, emotion, or desire by correcting the misconfiguration at the system level.
==7.8. Summary==
'''Structural failure modes reveal that effort breakdown is not always a question of will or value, but often a matter of internal misalignment.''' Through the lens of Lagunian Dynamics, CDA reframes common performance struggles as: Configurable, measurable, and addressable patterns, not moral failings or motivational gaps.
Understanding these patterns structurally enables more effective, compassionate, and scalable interventions across domains.

==8.1. Overview==
While Cognitive Drive Architecture (CDA) is defined as a structural field within cognitive psychology, its practical utility extends well beyond theoretical modeling. CDA provides a '''real-time system lens for understanding effort''' initiation, maintenance, and volatility in applied settings, including education, therapy, interface design, and high-performance environments.
Traditional interventions often focus on motivation, compliance, or discipline. CDA shifts the frame: '''engagement outcomes are seen as emergent from system configuration, not effort level or desire alone'''. This reframing enables more targeted, structurally intelligent intervention strategies.
==8.2. Education and Learning Design==
'''Challenge:'''
Students frequently fail to begin or persist in academic tasks, even when they care about the outcome or have the necessary skills. Rewards, punishments, and reminders offer limited reliability.
'''CDA Approach:'''
Engagement is treated as a function of variable alignment. Educators can design around structural bottlenecks instead of assuming motivational deficits.
{| class="wikitable"
|+ Educational design strategies aligned with CDA variables.
|-
! CDA Variable !! Educational Design Implication
|-
| Primode || Scaffold ignition (e.g., sentence starters, task cues)
|-
| CAP || Emotional hooks; relevance to student goals
|-
| Flexion || Multimodal entry points; differentiated task framing
|-
| Anchory || Minimize distractions; create focused spaces
|-
| Grain || Simplify unclear steps; reduce unnecessary complexity
|-
| Slip || Normalize variability; allow flexible pacing
|}
'''Example:'''
A student who delays writing despite valuing the topic may exhibit a '''Start Failure'''. Rather than assign blame, instructors can introduce ignition scaffolds, such as time-blocked start windows or pre-filled outlines, to structurally trigger Primode activation.
==8.3. Clinical Psychology and Therapy==
'''Challenge:'''
Clients often know what to do (e.g., use coping tools, maintain routines) but cannot execute consistently. This is often misunderstood as resistance or avoidance.
'''CDA Approach:'''
Therapists can model engagement failures as '''real-time misalignments''', not oppositional behavior. This reframes the problem from “Why aren’t they trying?” to “What’s structurally misaligned?”
{| class="wikitable"
|+ Clinical strategies for addressing Drive-related failure modes.
|-
! Failure Mode !! CDA Interpretation !! Clinical Strategy
|-
| Avoidance Loops || Grain ↑, Flexion ↓ || Reduce resistance; adapt task format
|-
| Inconsistent Progress || Anchory ↓, Slip ↑ || Normalize fluctuation; stabilize routines
|-
| Emotional Shutdown || Primode = 0, CAP ↑↑ || Distinguish urgency from ignition failure
|}
'''Example:'''
A client who repeatedly delays exposure exercises despite insight may show '''low Flexion''' and '''high Grain'''. Adjusting the exposure task’s form, e.g., shifting from verbal to visual or reframing the context, can structurally reduce resistance without requiring greater effort.
==8.4. Interface Design and Human-Computer Interaction (HCI)==
'''Challenge:'''
Users disengage from apps or platforms not because the goals are unclear, but due to hidden resistance, overwhelm, or unstable engagement. Traditional UX approaches often overlook the internal structure of cognitive effort.
'''CDA Approach:'''
Design interfaces to support Drive structurally by lowering Grain, increasing Flexion, and accommodating variability.
{| class="wikitable"
|+ Interface design goals mapped to CDA variables.
|-
! Design Goal !! Mapped CDA Variable(s)
|-
| Minimize friction/confusion || ↓ Grain, ↑ Flexion
|-
| Increase click-to-engagement || ↑ Anchory, ↑ Primode
|-
| Enable microtasking || ↑ Flexion, ↓ Grain
|-
| Allow intermittent use || Slip-accommodating design (autosave, sync)
|}
'''Example:'''
A complex productivity app might overload users with options, raising '''Grain'''. A CDA-informed redesign would prioritize '''progressive disclosure''', reduce task-switching costs, and embed '''ignition points''' (Primode triggers) into the UI flow.
==8.5. Coaching, Workflow, and Performance Strategy==
'''Challenge:'''
Even highly motivated professionals can struggle with consistency, creative block, or burnout. These issues are often misattributed to discipline or personality, missing the structural dynamics at play.
'''CDA Approach:'''
Optimize for '''system alignment''', not willpower. Coaches and strategists can use CDA to isolate bottlenecks and adjust performance environments structurally.
{| class="wikitable"
|+ CDA-informed adjustments for common effort issues.
|-
! Observed Issue !! CDA Interpretation !! Suggested Adjustment
|-
| Chronic procrastination || Start Failure (Primode = 0) || Use ambient cues, preloaded start points
|-
| Creative stagnation || Flexion ↓, Grain ↑ || Modify constraints or medium
|-
| Erratic output || Slip ↑ || Apply rhythm frameworks; normalize flux
|}
'''Example:'''
A freelance writer may produce brilliant content in bursts but unpredictably falter. High '''Slip''' is likely. Structuring creative work around consistent temporal anchors, e.g., same-hour daily drafts, can reduce entropy without limiting creative range.
==8.6. Benefits of CDA-Based Application==
CDA offers applied advantages over models that rely on internal traits, drive, or self-report:
* '''Structural diagnosis:''' Problems reside in system interaction, not personality
* '''Variable-specific interventions:''' Each misalignment has a structural lever
* '''Respect for variability:''' Slip is accounted for, not pathologized
* '''Cross-domain utility:''' Works in education, therapy, tech, performance
* '''Compassionate rigor:''' Enables precise modeling without blame
CDA makes engagement '''measurable''', '''modelable''', and '''modifiable''', a valuable framework wherever persistent action failure resists traditional solutions.

A client who repeatedly delays exposure exercises despite insight may show '''low Flexion''' and '''high Grain'''. Adjusting the exposure task’s form, e.g., shifting from verbal to visual or reframing the context, can structurally reduce resistance without requiring greater effort.
==8.4. Interface Design and Human-Computer Interaction (HCI)==
'''Challenge:'''
Users disengage from apps or platforms not because the goals are unclear, but due to hidden resistance, overwhelm, or unstable engagement. Traditional UX approaches often overlook the internal structure of cognitive effort.
'''CDA Approach:'''
Design interfaces to support Drive structurally by lowering Grain, increasing Flexion, and accommodating variability.
{| class="wikitable"
|+ Interface design goals mapped to CDA variables.
|-
! Design Goal !! Mapped CDA Variable(s)
|-
| Minimize friction/confusion || ↓ Grain, ↑ Flexion
|-
| Increase click-to-engagement || ↑ Anchory, ↑ Primode
|-
| Enable microtasking || ↑ Flexion, ↓ Grain
|-
| Allow intermittent use || Slip-accommodating design (autosave, sync)
|}
'''Example:'''
A complex productivity app might overload users with options, raising '''Grain'''. A CDA-informed redesign would prioritize '''progressive disclosure''', reduce task-switching costs, and embed '''ignition points''' (Primode triggers) into the UI flow.
==8.5. Coaching, Workflow, and Performance Strategy==
'''Challenge:'''
Even highly motivated professionals can struggle with consistency, creative block, or burnout. These issues are often misattributed to discipline or personality, missing the structural dynamics at play.
'''CDA Approach:'''
Optimize for '''system alignment''', not willpower. Coaches and strategists can use CDA to isolate bottlenecks and adjust performance environments structurally.
{| class="wikitable"
|+ CDA-informed adjustments for common effort issues.
|-
! Observed Issue !! CDA Interpretation !! Suggested Adjustment
|-
| Chronic procrastination || Start Failure (Primode = 0) || Use ambient cues, preloaded start points
|-
| Creative stagnation || Flexion ↓, Grain ↑ || Modify constraints or medium
|-
| Erratic output || Slip ↑ || Apply rhythm frameworks; normalize flux
|}
'''Example:'''
A freelance writer may produce brilliant content in bursts but unpredictably falter. High '''Slip''' is likely. Structuring creative work around consistent temporal anchors, e.g., same-hour daily drafts, can reduce entropy without limiting creative range.
==8.6. Benefits of CDA-Based Application==
CDA offers applied advantages over models that rely on internal traits, drive, or self-report:
* '''Structural diagnosis:''' Problems reside in system interaction, not personality
* '''Variable-specific interventions:''' Each misalignment has a structural lever
* '''Respect for variability:''' Slip is accounted for, not pathologized
* '''Cross-domain utility:''' Works in education, therapy, tech, performance
* '''Compassionate rigor:''' Enables precise modeling without blame
CDA makes engagement '''measurable''', '''modelable''', and '''modifiable''', a valuable framework wherever persistent action failure resists traditional solutions.

==9.1. Overview==
Although Cognitive Drive Architecture (CDA) is grounded in a formal structural theory (Lagunian Dynamics), its application does not require advanced tools, digital platforms, or psychological instrumentation. This module introduces '''low-tech methods''' for observing, tracking, and influencing Drive using analog, minimal, and accessible strategies.
These approaches allow individuals, educators, therapists, and coaches to engage with CDA’s structural logic '''without technical infrastructure''', making the framework viable in resource-limited settings or non-digital workflows.
==9.2. Principles of Low-Tech CDA Application==
Low-tech CDA implementation emphasizes '''internal system awareness and external scaffolding'''. The goal is not to enforce productivity but to support '''real-time configuration literacy'''.
'''Core principles:'''
* '''Structural Observation:''' Simple tools (journals, tables, verbal check-ins) help users map the six CDA variables daily.
* '''Minimal Scaffolding:''' Micro-prompts, rituals, and visual cues support key structural thresholds like Primode or Anchory.
* '''Iterative Realignment:''' Users adjust based on observed patterns, rather than pushing through misalignment.
Low-tech CDA helps people recognize where Drive breaks down structurally and how to intervene gently and precisely, without relying on motivation alone.
==9.3. Variable-Level Implementation Tactics==
Each variable in CDA can be supported through simple, analog strategies:
{| class="wikitable"
|+ Low-tech strategies to support CDA variables.
|-
! Variable !! Low-Tech Support Method
|-
| Primode || Use a ritual start phrase, visual cue, or time-based trigger (e.g., countdown, “3-2-1 begin”)
|-
| CAP || Brief reflection on urgency, value, or consequence before attempting task
|-
| Flexion || Break task into smaller steps; personalize form or framing (e.g., sketch instead of write)
|-
| Anchory || Use environmental anchors (e.g., background music, timer, physical boundaries)
|-
| Grain || Log friction points; simplify confusing components; modify tone or pacing
|-
| Slip || Allow fluid time windows; keep notes on inconsistency without judgment
|}
These tactics can be tracked using paper planners, index cards, sticky notes, or even whiteboards.
==9.4. Manual Configuration Mapping==
A '''daily configuration map''' allows users to reflect on Drive breakdowns structurally. A simple grid might look like:
{| class="wikitable"
|+ Sample self-assessment using CDA variables.
|-
! Variable !! Configuration (1–5) !! Notes
|-
| Primode || 2 || Couldn't start; hesitated repeatedly
|-
| CAP || 4 || Felt urgency to meet deadline
|-
| Flexion || 2 || Didn't know how to enter the task
|-
| Anchory || 3 || Focused briefly, then distracted
|-
| Grain || 4 || Felt emotional resistance
|-
| Slip || 3 || Output was inconsistent
|}
This self-report structure replaces judgmental narratives (“I failed”) with diagnostic clarity (“Flexion misalignment, Grain ↑”).
==9.5. MVA: Minimal Viable Application Format==
An MVA is a compact CDA implementation that uses only analog tools. It includes:
* A '''daily configuration table''' (see 9.4)
* A '''ritual start cue''' (e.g., a phrase, gesture, or dot drawn on a page)
* A '''Grain log''' (records recurring friction sources)
* A '''small-win tracker''' (e.g., moments when all variables aligned and action flowed)
These elements are deployable in:
* Paper journals
* Visual boards
* Sticky notes
* Session worksheets
No apps, devices, or logins required.
==9.6. CDA Coaching Prompts (Offline Use)==
In analog coaching, therapy, or education sessions, facilitators can use reflection questions to guide structural awareness:
* “Did you want to start, or were you structurally unable to?”
* “What part of your focus dropped first, attention, clarity, or emotional energy?”
* “Where was today’s Grain, external confusion or internal resistance?”
* “Could you reshape the task to match your current capacity?”
These prompts enable shared diagnosis and help users externalize system misalignment rather than internalize failure.
==9.7. Examples in Use==
{| class="wikitable"
|+ Low-tech CDA strategies across applied contexts.
|-
! Context !! Low-Tech CDA Strategy
|-
| Student journaling || Daily Drive log with checkboxes for Flexion and Grain
|-
| Therapy homework || Track Primode and CAP pre- and post-task
|-
| Creative projects || Mood board tracking Anchory and Slip visually
|-
| Coaching sessions || Weekly configuration reviews using planner inserts
|}
These approaches have been piloted in classrooms, therapy rooms, and performance coaching, often improving engagement without digital augmentation.
==9.8. Advantages of Low-Tech Implementation==
Low-tech CDA offers unique strengths:
* Zero cost
* Device-independent
* Personalizable
* Offline-capable
* Encourages reflection, not reliance
* Compatible with trauma-sensitive and neurodiverse learning models
'''It also supports self-regulated behavior through structural literacy, rather than willpower or app-driven nudging.'''
In a world increasingly dominated by automated behavior shaping, low-tech CDA offers an empowering alternative: structural self-understanding through minimal, human-centered tools.

==10.1. Overview==
Cognitive Drive Architecture (CDA), grounded in Lagunian Dynamics, is proposed not as a metaphorical or interpretive tool but as a '''formal, falsifiable field'''. Its central mechanism, the Drive Equation, posits structural interactions between six internal variables across three domains. These variables are intended to be '''operationalizable''', '''measurable''', and '''experimentally manipulable'''.
This module outlines empirical strategies for testing CDA’s validity, expanding its application, and exploring its compatibility with existing models in cognitive and behavioral science.
==10.2. Operational Definitions of Core Variables==
To move CDA from theory to testable science, its variables must be mapped to observable indicators. Below is a set of '''candidate operationalizations''':
{| class="wikitable"
|+ CDA variables with theoretical roles and measurable proxies.
|-
! Variable !! Theoretical Role !! Operational Proxy
|-
| Primode || Binary ignition gate || Action onset latency; readiness potential; “go/no-go” task activation
|-
| CAP || Affective-volitional modulator || Self-reported urgency; skin conductance; heart rate variability (HRV)
|-
| Flexion || Task-to-mind adaptability || Task reformatting choice rate; subjective task elasticity
|-
| Anchory || Attentional tethering || Eye fixation duration; blink suppression; focus time
|-
| Grain || Internal resistance or friction || Frustration reports; task aversion scales; cortisol response
|-
| Slip || Structural performance entropy || Intra-individual RT variance; accuracy volatility; keystroke irregularity
|}
These proxies are provisional and open to refinement as empirical data accumulate.
==10.3. Testable Predictions of the Drive Equation==
The Drive Equation enables concrete, falsifiable hypotheses. Key predictions include:
{| class="wikitable"
|+ Testable predictions from the CDA and their implications.
|-
! Prediction !! If Confirmed !! If Falsified
|-
| High CAP with Primode = 0 yields no initiation || Validates ignition gate dependency || Challenges binary ignition logic
|-
| Low Flexion impairs Drive even when CAP is high || Supports structural adaptability hypothesis || Suggests motivational override
|-
| Grain↑ weakens Drive despite high Anchory || Validates friction modeling || Implies denominator model needs revision
|-
| Slip persists across identical trials || Supports entropy theory || Suggests variability is affective or noise
|}
Each prediction maps directly to an interpretable system logic in CDA.
==10.4. Experimental Design Strategies==
Research on CDA may leverage controlled experiments that isolate structural variables while controlling for motivation and instruction.
'''Example paradigms:'''
* '''Primode Manipulation:''' Use pre-task rituals, verbal cues, or trigger scaffolds to activate ignition.
* '''Flexion Modulation:''' Vary task format (rigid vs. flexible entry points).
* '''Grain Adjustment:''' Alter instructions to create or reduce internal friction.
* '''Anchory Measurement:''' Use eye tracking or focus timers in self-paced tasks.
* '''Slip Detection:''' Repeated identical trials to assess internal entropy.
Sample dependent variables:
* Time-to-initiation
* Focus duration
* Task abandonment rate
* Self-reported resistance
* Behavioral drift (Slip)
These setups make CDA accessible for both lab-based and applied research.
==10.5. Cross-Model Integration and Compatibility==
CDA can be integrated with, or compared against, major psychological models:
{| class="wikitable"
|+ Alignment of CDA variables with established psychological models.
|-
! Model !! CDA Correspondence
|-
| Expectancy-Value Theory || CAP = value expectancy; lacks Primode structure
|-
| Dual Process Models || CDA provides substructure for “System 1/System 2” transitions
|-
| Executive Function || Anchory and Flexion correspond to sustained attention and task switching
|-
| Self-Determination Theory || Grain and CAP reflect tension between autonomy, competence, and effort
|}
CDA is not positioned to replace these models, but to '''add a structural layer''' beneath their functional outputs.
==10.6. Research Contexts and Applied Fields==
CDA offers testable value in a range of domains:
* '''Education:''' Diagnosing procrastination, testing assignment framing (Flexion)
* '''Clinical Psychology:''' Modeling avoidance, behavioral activation misfires
* '''HCI/User Experience:''' Interface engagement decay, feature friction mapping
* '''Workplace Studies:''' Burnout profiling, intra-task variability
* '''Human Performance:''' Mapping focus breakdown in complex task environments
These contexts allow high ecological validity and field-tested model refinement.
==10.7. Open Challenges and Methodological Considerations==
Despite its tractability, CDA research faces key challenges:
* '''Isolating Variables:''' Interdependencies between Primode, CAP, and Flexion may obscure causality.
* '''Operationalizing Primode:''' As a binary latent gate, it is hard to observe directly.
* '''Slip vs. Error:''' Behavioral entropy must be distinguished from attention lapses or fatigue.
* '''Equation Complexity:''' Nonlinearity and asymmetry complicate regression-based modeling.
These are addressable through iterative experimental refinement and cross-modal validation.
==10.8. Suggested Research Agenda (Phase I–IV)==
{| class="wikitable"
|+ Proposed research phases for validating the CDA framework.
|-
! Phase !! Research Focus !! Description
|-
| Phase 1 || Variable Validation || Establish reliability and distinctiveness of operational indicators
|-
| Phase 2 || Equation Testing || Manipulate variables (e.g., 2×2 Primode × CAP) to test Drive outputs
|-
| Phase 3 || Applied Studies || Field research on CDA variables in real-world contexts (e.g., student adherence, app usage)
|-
| Phase 4 || Model Refinement || Adjust Drive Equation structure based on empirical fit and observed exceptions
|}
This staged approach allows both '''basic science validation''' and '''applied translation'''.
==10.9. Next Steps for Researchers==
Initial pilot studies can begin immediately using lightweight tools:
* '''Drive Log Diaries:''' Participants self-track variables during task attempts
* '''Task-switch Experiments:''' Measure Grain and Flexion as task structure changes
* '''Latency-to-Engage Trials:''' Examine Primode timing under CAP pressure
* '''Inconsistency Mapping:''' Use Slip to profile variability in high-skill individuals
Findings from these efforts may confirm, refine, or challenge CDA, fulfilling its design as an empirically grounded structural model, not a metaphor or heuristic.

==11.1. Purpose of the Course==
This course introduced Cognitive Drive Architecture (CDA) as a structural, domain-independent framework for '''modeling effort and engagement''' in cognitive systems. Grounded in Lagunian Dynamics, CDA shifts the understanding of Drive from vague motivational traits to '''formally defined internal variables''' interacting within a system equation. Its central goal is to explain how effort arises, when it breaks down, and how it can be realigned, not by boosting motivation, but by structurally configuring the system that supports it.
==11.2. Key Concepts Recap==
{| class="wikitable"
|+ Caption text
|-
! Core Element !! Summary
|-
| Lagunian Dynamics || Foundational theory modeling cognitive effort as the output of real-time variable interaction
|-
| Drive Equation || <math>Drive=\left ( \frac{P^C\times F}{A+G} \right )+S</math>
|-
| Ignition Domain || '''Variables:''' Primode (ignition gate), CAP (volitional amplifier)
|-
| Tension Domain || '''Variables:''' Flexion (task adaptability), Anchory (focus stability), Grain (friction)
|-
| Flux Domain || '''Variable:''' Slip (systemic entropy/variability)
|}
These variables are designed to be observable, testable, and alterable, allowing real-time diagnosis and adjustment of engagement conditions.
==11.3. Failure Modes and Configuration Patterns==
CDA offers a '''non-pathologizing''' model of effort breakdown, reinterpreting struggles as system misconfigurations:
{| class="wikitable"
|+ Drive failure modes with core misconfigurations and outcomes.
|-
! Failure Mode !! Primary Misconfiguration !! Typical Outcome
|-
| Start Failure || Primode = 0 || No initiation despite desire
|-
| Motivated Stall || CAP ↑, Flexion ↓ || Urgency without movement
|-
| Drift Collapse || Anchory ↓, Grain ↑ || Focus dissolves mid-task
|-
| Resistance Spiral || Flexion ↓ + repeated failures || Cyclical disengagement
|-
| Entropy Drag || Slip ↑↑ || High variability; inconsistent output
|}
Understanding these patterns enables '''compassionate''', '''structural intervention''' rather than reliance on discipline or motivation.
==11.4. Applications by Domain==
CDA has practical uses across disciplines:
{| class="wikitable"
|+ Domain-specific applications of CDA variables.
|-
! Domain !! Example Use
|-
| Education || Scaffold Flexion and Primode to reduce disengagement
|-
| Therapy || Address behavioral avoidance via Grain/Anchory modeling
|-
| Interface Design || Lower Grain by simplifying flow; boost Anchory with layout stability
|-
| Coaching || Track system variability; stabilize routines to reduce Slip
|}
Even '''low-tech implementations''' (Module 9) can yield significant insights using simple logs, cues, or environmental scaffolds.
==11.5. Research Opportunities==
CDA is designed to be '''empirically testable''', not just theoretically elegant:
* Operationalize core variables via physiological or behavioral measures
* Test Drive Equation predictions in controlled contexts
* Integrate CDA with motivational, executive function, and attentional models
* Validate Slip as a structured, non-random source of variability
This positions CDA as both a '''practical tool''' and a '''scientific hypothesis''' ready for falsification and refinement.
==11.6. Learning Objectives Revisited==
By completing this course, learners should now be able to:
* Understand and interpret the '''Drive Equation'''
* Recognize '''failure modes''' as structural, not personal
* Apply CDA across contexts (education, therapy, design, coaching)
* Use '''low-tech strategies''' to self-monitor and scaffold Drive
* Design or interpret '''empirical studies''' testing CDA’s predictions
* Rethink effort and inconsistency through a '''system configuration lens'''
==11.7. Continuing Exploration==
Suggested next steps for learners:
* Track a week of tasks using a Drive Log
* Identify a personal “Start Failure” and test a Primode scaffold
* Redesign one task to increase Flexion or reduce Grain
* Share CDA with a colleague or client to map a breakdown nonjudgmentally
* Draft a mini-case study on how Slip impacts your own productivity
==11.8. Course Closing Statement==
Cognitive Drive Architecture reimagines effort not as a trait, not as discipline, and not as motivation, but as a '''system configuration problem'''. It gives us a new lens to interpret engagement, failure, and volatility without shame, blame, or mystification.
Whether you’re a student, educator, therapist, designer, or researcher, CDA offers a way to '''understand action, or inaction, with precision and humanity'''.
The next version of this model will be shaped not just by data, but by the lived experiences of those who apply it. Your logs, reflections, failures, and insights are part of that evolution.

==11.1. Purpose of the Course==
This course introduced Cognitive Drive Architecture (CDA) as a structural, domain-independent framework for '''modeling effort and engagement''' in cognitive systems. Grounded in Lagunian Dynamics, CDA shifts the understanding of Drive from vague motivational traits to '''formally defined internal variables''' interacting within a system equation. Its central goal is to explain how effort arises, when it breaks down, and how it can be realigned, not by boosting motivation, but by structurally configuring the system that supports it.
==11.2. Key Concepts Recap==
{| class="wikitable"
|+ Caption text
|-
! Core Element !! Summary
|-
| Lagunian Dynamics || Foundational theory modeling cognitive effort as the output of real-time variable interaction
|-
| Drive Equation || <math>Drive=\left ( \frac{P^C\times F}{A+G} \right )+S</math>
|-
| Ignition Domain || '''Variables:''' Primode (ignition gate), CAP (volitional amplifier)
|-
| Tension Domain || '''Variables:''' Flexion (task adaptability), Anchory (focus stability), Grain (friction)
|-
| Flux Domain || '''Variable:''' Slip (systemic entropy/variability)
|}
These variables are designed to be observable, testable, and alterable, allowing real-time diagnosis and adjustment of engagement conditions.
==11.3. Failure Modes and Configuration Patterns==
CDA offers a '''non-pathologizing''' model of effort breakdown, reinterpreting struggles as system misconfigurations:
{| class="wikitable"
|+ Drive failure modes with core misconfigurations and outcomes.
|-
! Failure Mode !! Primary Misconfiguration !! Typical Outcome
|-
| Start Failure || Primode = 0 || No initiation despite desire
|-
| Motivated Stall || CAP ↑, Flexion ↓ || Urgency without movement
|-
| Drift Collapse || Anchory ↓, Grain ↑ || Focus dissolves mid-task
|-
| Resistance Spiral || Flexion ↓ + repeated failures || Cyclical disengagement
|-
| Entropy Drag || Slip ↑↑ || High variability; inconsistent output
|}
Understanding these patterns enables '''compassionate''', '''structural intervention''' rather than reliance on discipline or motivation.
==11.4. Applications by Domain==
CDA has practical uses across disciplines:
{| class="wikitable"
|+ Domain-specific applications of CDA variables.
|-
! Domain !! Example Use
|-
| Education || Scaffold Flexion and Primode to reduce disengagement
|-
| Therapy || Address behavioral avoidance via Grain/Anchory modeling
|-
| Interface Design || Lower Grain by simplifying flow; boost Anchory with layout stability
|-
| Coaching || Track system variability; stabilize routines to reduce Slip
|}
Even '''low-tech implementations''' (Module 9) can yield significant insights using simple logs, cues, or environmental scaffolds.
==11.5. Research Opportunities==
CDA is designed to be '''empirically testable''', not just theoretically elegant:
* Operationalize core variables via physiological or behavioral measures
* Test Drive Equation predictions in controlled contexts
* Integrate CDA with motivational, executive function, and attentional models
* Validate Slip as a structured, non-random source of variability
This positions CDA as both a '''practical tool''' and a '''scientific hypothesis''' ready for falsification and refinement.
==11.6. Learning Objectives Revisited==
By completing this course, learners should now be able to:
* Understand and interpret the '''Drive Equation'''
* Recognize '''failure modes''' as structural, not personal
* Apply CDA across contexts (education, therapy, design, coaching)
* Use '''low-tech strategies''' to self-monitor and scaffold Drive
* Design or interpret '''empirical studies''' testing CDA’s predictions
* Rethink effort and inconsistency through a '''system configuration lens'''
==11.7. Continuing Exploration==
Suggested next steps for learners:
* Track a week of tasks using a Drive Log
* Identify a personal “Start Failure” and test a Primode scaffold
* Redesign one task to increase Flexion or reduce Grain
* Share CDA with a colleague or client to map a breakdown nonjudgmentally
* Draft a mini-case study on how Slip impacts your own productivity
==11.8. Course Closing Statement==
Cognitive Drive Architecture reimagines effort not as a trait, not as discipline, and not as motivation, but as a '''system configuration problem'''. It gives us a new lens to interpret engagement, failure, and volatility without shame, blame, or mystification.
Whether you’re a student, educator, therapist, designer, or researcher, CDA offers a way to '''understand action, or inaction, with precision and humanity'''.
The next version of this model will be shaped not just by data, but by the lived experiences of those who apply it. Your logs, reflections, failures, and insights are part of that evolution.
