I've got a new paper that I'm proud of: arxiv.org/abs/2507.17936. While teaching discrete math, we got some results about the topology of finite subsets, finite tuples, and compact subsets of a given space. I was teaching combinatorics, so I wondered about ordered compact subsets. This is the result

AI companies are just like every other profiteer horning in on public education money. They aren't trying to fool educators, who know better. They're trying to fool politicians, who are stupid af and easily bought.

@scalzi.com's Kaiju Preservation Society was the perfect book to help me through *8* hours of flight delays today. What a fun read!

Today was my first day at a non academic job since I earned my PhD.
Academia turned out to be a corrosive environment for me, but I hope to continue my research as a hobby now.
I'm hopeful that I can thrive in my new work environment and also do some good for the world.

I found this to be a really interesting video. A good attempt to separate Feynman the man from his stories and his physics. Also an indictment of the popular science publishing industry.

I absolutely loved working on this cover art w/ @statsteph.bsky.social, @ivelasq3.bsky.social, & Rebecca Powell! Fantasy maps + data? What a dream.

The joy of finishing the thing that means you can get back to the thing you need to finish before you can get back to doing the thing you're supposed to be doing.

Have any of y'all ran a senior seminar/independent study in set theory before? I'm running one this fall with an interested, talented student who lacks any real set theory experience.
Any advice you have is appreciated.

In honor of the Chinese remainder theorem, I'm going to refer to Newton's method as the British root approximation theorem from here on out.

Lol some arXiv moderator reassigned my preprint to CS.DB - does this mean I'm a computer scientist now? arxiv.org/abs/2404.05778

It's the moment you (may) have been waiting for!

The first episode of the History of Philosophy in China, which will appear every other week from now on, from me and co-author Karyn Lai.

The first episode looks at the many meanings of Dao:

Wonka was pretty good. I have yet to see something from Paul King that I dislike. He just needs to get better trailers.

I'm really glad my terrible teenage edgelord nonsense was limited to Xanga and instant messenger. I can't imagine being a teenager today.

My coauthor and I just had a paper accepted. Cusco maps are neat and the name always makes me think of the emperor's new groove.
