Nothing in particular, though I like anything futurist or math. Saw you mention you had an interest, and from Ulam quote I found out about Ulam spirals (kinda cool). I have been enjoying math stuff th...

I was quite fond of mathematical logic and associated fields like model theory and non-standard algebra (hyperreal numbers). Using the hyperreal numbers in math education would actually be pretty cool.

Once I made a small fractal generator with JavaScript to make the fancy images I used in the Fractal Future Forum. But that was actually rather elementary. Huh, maybe I could turn that into an actual app. Migrating it to Rust and Wasm should definitely amp up its performance.

Mostly I focused on geometry at university: Differential geometry, algebraic topology, a little bit of algebraic geometry. In my last job in geoinformatics I actually needed about zero of that, but having had that background was still nice.

Ah, and I considered coming up with a "coviariant" notation for ordinary mathematics. The usual notation is actually "contravariant" in the sense that you need to read f(g(x)) from right to left. A covariant notation would be something like x|g|f (first apply g to x then f).

Actually, I am not doing much with math right now, but focus on getting into the Bitcoin / Lightning / Nostr dev space.

Oh cool, that's right up my alley, though it sounds like you know far more than I do (good for me, sucks for you). Hyperreals, I just looked them up, seems to be very similar to Surreals, just not a proper class. I'll have to look into them more someday soon. Covariant notation seems a bit like reve...
