This is a fully visually evident proof of the fact that the diagonal of a regular unit pentagon is the golden ratio. arxiv.org/abs/2610.18903

This bad boy can fit so many nationalized space companies inside it you wouldn’t believe it

PSA: For anyone writing a recommendation for the NSF grad fellowship this year, recs are due on Fri Oct 16, 8pm Eastern, cleverly *before* the actual application deadline. This tidbit isn't on the NSFGRF front page anymore; it's buried inside the program solicitation:

For A Few Dollars More For Tax Purposes

the answer is no, they do not know if many of these results are just slop, and have already withdrawn 3 of them

The Association for Human Mathematics (AHM) statement on OpenAI’s October 6 release of mathematical documents just dropped! www.ahmath.org/statements

If Metro is determined to practice subtractive change, we should demand that they match their cuts with growth and new investments. Not in things like fare gates, which tilt at windmills, but in services that meaningfully improve the experience and functionality of transit in this region.

I had a conversation w a Lyft driver a few weeks ago that I still think about. I hope this musician, eager to share her art, finds her way to teaching. While the conversation started rocky, Im glad she got an opportunity to talk about her ambitions. Piano teachers are way more valuable than A.I.

Trans women are women. There is no asterisk in that sentence, and I have absolutely no time for anything that suggests otherwise, including but not limited to "except when they play sports".

here is the american mathematical society's statement on the navier-stokes issue

Among other things, it sounds like at one point, this involved researcher A demanding that B remove C from authorship of a paper, on which A would not also be a coauthor. Is there any circumstance under which that's consistent with academic ethics?

For anyone not following the drama, there's been apparently a big development in ai math, along with some accusations of very bad behavior by OpenAI. But we don't have details yet. If I understand it, Buckmaster and Levent Alpoge made a big discovery on Navier-Stokes. Events go something like this:

It is Followers' Cats Week for the upcoming week! I am going to creep through my followers on my different social media and pick a random cat from someone's profile. For today, it is the one and only Vertical Benny! Cat of @taterdash.bsky.social #art #cat #illustration

In yesterday's intro-to-proof class, I managed to invoke the Blues Brothers and Dolly Parton in the same example problem. The problem: use quantifiers to express the statement "everybody loves somebody" in terms of symbolic logic.

Actually good #mathnews? A proof that there are infinitely many pairs of consecutive primes whose difference is at most 240 No, I don’t understand the proof, but I can appreciate the result #MathSky #SciSky

I'm at a world championships watch party that's holding a coloring contest. #PlayPokemon

Alright, I'll put in a prediction for #PokemonTCG worlds in 2027: Either Paris or Singapore.

We need to build a second Fair above, or below, the current Fairgrounds

Ok so, this shirt was a HUGE hit at the fair. I've never been stopped more for anything remotely as much as people of all ages stopped to compliment this shirt. @racketmn.com if you find a vendor at the fair to sell these next year, they'll sell like Amish Donuts.

I assume they already had this in their repertoire, but I do like thinking that someone got the news over dinner yesterday, stayed up all night arranging, and had this ready to rehearse first thing in the morning.

(1/2) Since I haven't seen anyone else mention this one... It was an open secret that Dolly Parton secretly funded a massive number of southern high school bands, most especially predominantly Black high schools. A marching band member in her youth, Dolly never forgot the joy that playing snare drum

The fell eye of the cosmic Cookie Monster turns toward us. All shall crumble.

1/3: Someone has been harassing me non-stop this past week to try to stop me from attending Worlds. They created tickets w/ Pokémon Support, accounts here, Instagram, Bluesky, YT & now they're emailing large creators their fake screenshots. Known accounts are listed in reply.

I wouldn't call myself a cartoonist, but I had the vision and just needed it to be on paper to the best of my ability.

Who put the Rice Marching Owl Band in charge of the Secret Service?

wow what a blessing to exist

A PSA to my fellow cis people who are (or want to believe they are) trans allies If you are getting pushback from trans people and your reaction is to be all “no! not me! I’m one of the good ones!” please remember that “being one of the good ones” is something you DO, not something you ARE

Went to the Arch this morning and drew some things nearby. #art #stl

wait.

my cat is the prettiest cat in the whole world and she chooses to be my best friend and she has little mittens and big ol marble eyes and also I love her

Hello from #SGDQ2026 finale night!

My parents' Doonesbury collection (along with asking them to explain the jokes) was probably the second-best American history textbook I ever had.

SHINY RATICATE GET!
