Selig's bulldog 😈 Building civilization demands we make better tools for thought; Geometric Algebra 📐 is going to be a big part of that!
I've made a video about non-Euclidean geometry in AI! youtu.be/_CJZeTEcb1A maaaaaan things get beautiful when you go to second order 🥹

So cool!
New thing! @jrcpl.us and I have been exploring home-made software. We made a prototype of a tool for making scrappy little apps for you and your friends.

Geometrically, it seems to me that a universe with exactly three spatial dimensions is the the only option if we are to have a a concept of "spaghetti"

The equator has a relationship to the north and south poles that we call "dual". The poles are the furthest you can be, on earth, from the equator.
TIL Buenos Aires and Shanghai have about the same relationship to the Madrid->Nairobe flight path!

I found time to re-edit this video I made about conformal GA :) www.youtube.com/watch?v=kBri... 1h45m may seem like a lot but it was more before!
If you want to learn CGA, you really want Projective GA first. PGA does distances/angles/planes/lines/points/rotations, CGA is more advanced!

My friend Jeff wrote a cool paper connecting Projective Geometric Algebra and concepts like cosets and quotients! Here's us chatting about it for 2 hours 😃😃

A hydraulic erosion simulation, but it's a bit finicky and unstable and I'm not super happy with it. Try it live here: observablehq.com/@rreusser/hy...
