Finally, a hot take I agree with

Diamond Open Access for the win!! ACTG :) Love the name!

new journal from the Association for Mathematical Research just dropped...

my love-letter to the humanities: a book on mathematics & poetry. it starts with the question: "Where the Hell is Heaven?" thesis: in imagining the afterlife, poets from ancient times used the same imaginative skills that geometers and topologists use to imagine abstract

25 years ago, I struggled with whether to do mathematics or music as a profession. Then one of my University teachers mentioned off-hand that he'd had a similar struggle, and chose as profession what would be harder to make a hobby. Now he's written a book only he could write.

Want to generate point clouds? Our (Ernst Röell) #NeurIPS2025 paper shows a topology-driven method that is fast, simple, and high-quality. 🔥 1/n

> Went in to work dressed as a reporter for Halloween. > Asked pure mathematicians "what are some real world applications of your work?" > Asked applied mathematicians "which of your theorems are you most proud of?" > Great day.

FFS Grok, this headline should be WILL STILL WON'T STILL BE MANAGER

not gonna screen-shot & dump on those commenting on the depth of linear algebra... for i too was once a fool and did not appreciate its beauty (a long time ago)... better to point out beauty than ridicule stupidity... so here is something beautiful about linear algebra (or, even,

there once was a writer named witt whose actions would shock you (a bit) his piece tried to playtrices with products of matrices and math nerds just want him to quit

Picked this off the bookshelf and wondered how Petersen Geometries met his wife Tilde. How's your weekend been?

This is absolutely glorious.

Just wrote a gentle introduction to injective morphisms between orbifolds. Please check out my substack.
