Polyomino loops: https://medium.com/swlh/polyomino-loops-fc8f6fc92c2f

Matthew Yuan wonders, if you play billiards in a polyomino and try shooting a ball diagonally from the midpoint of each of the polyomino edges, how to count the number of loops that these billiard paths will link up into. It's somewhat related to the African lusona drawings that I discussed at https://11011110.github.io/blog/2020/08/02/sona-enumeration.html.

Okay, those black-hole researchers clearly use #Ubuntu.

Two mathematicians messing around on Discord. With @saulsch.

@Placholdr This is the practice, in programming, of explaining your problem to a literal rubber duck. Often the process of explaining the problem helps you figure it out.

There does also seem to be an effect where, the more publicly you post your confusion, the more quickly you realize your silly mistake. Finally, in the classroom, your ability to do math is inversely proportional to your proximity to a whiteboard.

@Placholdr You figured it out *because* you posted the question. #RubberDucking

Who called them dog breeds and not barketypes?

here's a showcase of some of the animations!

Sometimes #learning more about something does not feel like gaining knowledge, but more like the stupid (misconceptions and simplifications you believed to be true) leaving your body.

I found this article to be personally relevant.
My parents had to slip over the border for their wedding. At the time, "mix-race" marriage was illegal in the state of Virginia.

Wednesday May 9th, Tai-Danae Bradley and I are giving talks on entropy and category theory.

Her talk will dig into the consequences of an amazing fact: the function at the heart of entropy, namely

d(x) = -x ln x ,

obeys a version of the product rule!
