I have two wolves inside me—a mathematician and an artist—and I feed them equally well.

All of my art is made without AI. I find generative AI repulsive. I have no desire to use it, nor do I wish to collaborate with anyone who uses it.
Two knight's tour (32x32 and 64x64). Two terms of an infinite sequence of tours.

I had a really nice couple of days at Oberlin College hanging out with @baabbbaash.bsky.social, his colleagues, and students! While walking around campus, I saw this unusual window. Assuming it is the unit circle, what's the equation of the ellipse?

[Edited] On behalf of the Oberlin Mathematics Department, I am thrilled to say that Dave Richeson will be delivering this year's Tamura/Lilly Lecture, "A Romance of Many (and Fractional) Dimensions," on 11.6.25. The reception will be at 3:30pm in King 203. The talk will be at 4:30pm in King 337.
I'm excited to give this year's Tamura/Lily lecture at Oberlin College (this Thursday, November 6, 4:30 pm). It will be nice to see @baabbbaash.bsky.social, his colleagues, and his students. If you are at Oberlin, stop by! www.oberlin.edu/events/mathe...

For nearly 80 years, an algorithm called the simplex method has been one of the most widely used tools for when a logistical decision needs to be made under complex constraints. A new update makes it faster than ever. www.quantamagazine.org/researchers-...

The leading approach to the simplex method, a widely used technique for balancing complex logistical constraints, can’t get any better.

What are folks’ recommendations for places that 3D print in metal (say, for math sculptures)?

I never have printed in metal before, but I’ve got a couple of designs that I’m really happy with…(and there was prize money from the math fest art show!)

An open knight's tour of a 128x128 chessboard. The knight starts in the lower left corner, finishes near the lower right corner, and visits each of the sixteen 32x32 regions in the same order that they'd be visited by a second-stage Hilbert curve. #mathart

Not receiving a salary raise in an era of rampant inflation is essentially a pay cut. But so is the laying off of support staff whose jobs faculty are expected to absorb.

Doing tech support, extra advising, admin assistant duties, etc. = less time for the work of being a teacher / faculty member.

This is how you interview people from the Trump admin; past , present, and future. Full stop.

So well done.
Me: "So which country should @aoc.bsky.social go back to?"
Mick Mulvaney: "She's an American citizen."
Me: "So why did Trump tell her to go back to her country?"

I asked former Trump WH chief of staff Mulvaney if he ever challenged his then boss on his racist tweets.

The US will stop making pennies in 2026, which got me thinking about what to do with a giant collection of too-expensive, low-value coins. Here's what I made with them.

Sick of everything being Orwellian or Kafkaesque. I demand more Scarrylous situations, where animals drive vehicles and run small businesses.

A knight's tour of a 32x32 chessboard. The knight's path is unicursal. If you start in the lower left corner and follow the path move by move, you will visit each square once and only once and end near the lower right corner. Inspiration: Szpakowski's linear ideas. #mathart #mathsart #orms #chess
