In August of Japan, the method of cutting pizza and cake into equal areas as shown in the figure was popular on Twitter! It can be found at the following URLs:
(I was most inspired by twitter.com/potetoichiro .)
cf. zh.wikipedia.org/wiki/%E6%8A%A
and arxiv.org/abs/1512.03794

Recently I was taught the following two expressions formula,

From youtu.be/dO40DZk-qNU , I found wolframalpha.com/input/?i=(1%2 , Still I can't prove this proof yet.
It does not matter at all,
"Tangential quadrilateral" en.wikipedia.org/wiki/Tangenti has an inscribed circle if only three sides (The fourth side must be $$a+b-c$$ .) are decided (The shape is completely determined by the determination of another angle).

Now I make PDF shinshu.us/itou.pdf , Thanks! We will plan to generalize Twitter "じゃがりきんａｐｕ長ピーポ黄金角形" twitter.com/wasanp_/status/109 in the future.

@jsiehler I'm playing your with so exciting! homepages.gac.edu/~jsiehler/ga (If I understand mechanism that one piece moving one time anyway is counted as 1-move, I may be able to reduce MOVES more!)

Now, I am interested in the following three.

1: "Sums of three cubes" en.wikipedia.org/wiki/Sums_of_ has generalized parametric representation "A New Method in the Problem of Three Cubes" arxiv.org/abs/1802.06776 (cf. ex. Old article in Japanese asahi-net.or.jp/~KC2H-MSM/math ).
2: DANIEL SCHER "A DOUBLE SPIRAL FROM DAVID HENDERSON" sineofthetimes.org/a-double-sp
3: Paul Bourke "Danzer Aperiodic Tiling" paulbourke.net/geometry/tiling telling by GirihApp@Twitter twitter.com/GirihApp/status/11 . I do similar one of the attached image

The migration of influencers “sends a signal to the people running Twitter that influencers can move out – perhaps completely – if the company doesn’t play fair. Mastodon has already begun to enjoy network effects and FOMO that will attract, initially at least, a higher quality user base. If Twitter chooses to ignore the signal, then Mastodon will more likely take off.”

Still some people using the WordPress comments plugin, I might update it.

I've made a new thing. I've called it "The Homologist's Nightmare".

@no_TL And I found the image's duality. I'm very surprised because I didn't know this !

@no_TL In September, I was studying the "inverse geometry" en.wikipedia.org/wiki/Inversiv of Japanese mathematics "Wasan" en.wikipedia.org/wiki/Japanese. I thought the following image was the simplest and most beautiful result

We've just released #Halcyon 2.4.4 with the following changes:
- Added a option to rewrite all #Birdsite links to a #Nitter instance which can be set by the instance admin
- Click on animated GIFs is now handled in the same way as normal images
- Enabling full height for images does now also work for animated GIFs

@no_TL And I'm testing the crossposter.masto.donte.com.br Thanks!

@no_TL addons.mozilla.org/ja/firefox/ can tweet from WebUI (visibility: "public" (& "unlisted" until v2.4?))! Well, I still can't CW etc…

@bremner One other thing -- in addition to .tex files we also support using .md (markdown) files with embedded latex. This can be useful for (collaborative) notes, since it's more friendly than full latex.

@bremner Thanks for you trying cocalc.com! Feel free to click Help button in cocalc in the upper right for any questions about course plans versus subscriptions or anything else, or if you just want to video chat with us.

I founded CoCalc to create a company that would be ideally aligned with heavily supporting open source math-related software development, and that is our ultimate goal.

Thanks to @dansup I can use #Fedilab with #Pixelfed 👍
Now it's time to work on improvements with the app and contribute as much as possible to Pixelfed.
