Selig's bulldog 😈 Building civilization demands we make better tools for thought; Geometric Algebra 📐 is going to be a big part of that!

What if light travelled super slow? Part 2 Things get even weirder with moving objects!

I ported Super Monkey Ball to a website. You can access it in the replies. (or just type what you see in the video, I'm not your boss.)

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!

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!

www.twitch.tv/videos/23307... 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 😃😃
