Did GPT give the correct proof in one shot?, or was it a more iterative process with the prompter?

Seems like there was a lot of work done by humans in completing this proof (much of it done by one of the worlds most eminent mathematicians) so I wouldn't personally give GPT the credit for this one, just for coming up with the initial idea.

Would be fun to add some finite categories to this. Might be something like a categorical OEIS

I still have your tikz presets for drawing Petri nets like that, might break them out if I'm feeling nostalgic :)

Actually nevermind I think it was Lawvere's idea first

2025-09-14 10:04:50 UTC

https://arxiv.org/abs/2509.05900 I had this idea years ago but I never wrote a paper about it...just a blog post https://jadeedenstarmaster.wordpress.com/2019/03/31/dynamical-systems-with-category-theory-yes/
Would have been nice to get a citation...

Did you ever learn the Hamilton Jacobi Bellman equation? That's what I'm focusing on at the moment since I'm also interested in control theory and variational calculus :)

2025-05-25 14:36:00 UTC

I've been learning about PDEs. I think they are a lot fun and even more vibes based than category theory.

I am conflating configuring Pythagorean Theorem with what I want to call Pythagorean Fact...that a^2 + b^2=c^2. The Babylonians certainly discovered the fact!

2025-04-10 20:39:58 UTC

Today I learned Pythagorean Theorem was not discovered by Pythagoras, it was actually discovered 13-15 centuries earlier in Iraq!

without admitting to watching her videos I'll say that she thinks the majorana qubits are fake.

Was Sabine Hoffensfelder right about the Majorana Qubits?

I think my biggest problem for academic jobs was that all my options were in a CS department. I'm much better at teaching calculus than iCS topics which I never learned as a student.

Yes I tried for teaching jobs and academic jobs, they wanted me to move all over the world and I wasn't lucky enough to get any of the ones in Glasgow.
I would still be happy to get an academic job in this city, but hearing about what it's like from my friends who are academics...it seems a lot harder and more stressful than what I currently have.

No but I don't actually work on AI directly, I work on other things and argue that later on it will be useful for making AI better.

You've had the luxury of retirement...and I've had to make some choices. Although I am working on AI, I am comforted by the fact that my job gives me a lot of independence and freedom to work on what I like.

The way that accelerationism has become an excuse for fascism has made me believe more in the opposite philosophy: decelerationism. At the very least I believe that everybody should have the right not to work, especially if we know our work will just hasten the capitalist apocalypse.

I would be interested in reading your take on Noether's theorem. Have you written it down somewhere?

Breaking: Trump says that every subobject classifier in a topos has cardinality 2.

wow magnetohydrodynamics is a topic I quite enjoy. I studied it very briefly in undergrad because it was my undergrad advisor's research specialty. Excited to get into your blog post!

I visited it a few years ago and it was an incredible museum so I hope it survives. I've also got some family in Santa Monica that I haven't heard from yet so I hope they're okay!

I think management consultants are easily sold on the idea of category theory but the actual practice requires too much paradigm shifting

I don't know what debrujin indices are and I'm worried it's too late to ask 😂

They should make journals for papers that are only partially completed
