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:
twitter.com/mathlava/status/11
twitter.com/5Hanayome/status/1
(I was most inspired by twitter.com/potetoichiro .)

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).
Thanks from twitter.com/takatasennsei !

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.”

@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

You can download it from notabug.org/halcyon-suite/halc but please don't forget to add the new option in your config.ini

@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.
