$\begingroup$ Not an answer to your question, but another high-quality video on this topic: youtube.com/watch?v=Zv-XNlE1s8E $\endgroup$Sam Hopkins– Sam Hopkins ♦2026-01-05 00:19:47 +00:00Commented Jan 5 at 0:19

1$\begingroup$ From Wikipedia: "Charles Pugh's chicken-wire models (subsequently stolen from the Mathematics Department at Berkeley)". But no citation to the theft is given. $\endgroup$Alex Kruckman– Alex Kruckman2026-01-05 03:48:26 +00:00Commented Jan 5 at 3:48

$\begingroup$ just to mention it: the chicken wire model is actually a Fullerene graph and must contain 12 pentagons; the rectangular grid computer animation shows a socalled cubed sphere. would be interesting to have the mathematical model of the physicsal chicken wire model $\endgroup$Manfred Weis– Manfred Weis2026-01-05 06:13:09 +00:00Commented Jan 5 at 6:13

5$\begingroup$ I believe the chicken-wire models were based on Bernard Morin's sphere eversion. They were stolen sometime during a summer weekend in the late 1970s. $\endgroup$Daniel Asimov– Daniel Asimov2026-01-05 10:49:17 +00:00Commented Jan 5 at 10:49

- Always respect the author’s intent
- Don’t use edits to reply to the author
How to Format
-
create code fences with backticks ` or tildes ~
```
like so
``` -
add language identifier to highlight code
```python
def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end
- _italic_ or **bold**
- quote by placing > at start of line
- to make links (use https whenever possible)
<https://example.com>[example](https://example.com)<a href="https://example.com">example</a>

$\sin^2 \theta$
How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. ag.algebraic-geometry), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
