几何代数快速入门（Sudgylacmoe）

An animated introduction to geometric algebra, presented as a language that can describe most of physics. It was made with manim and covers multivectors and how they generalize familiar tools like cross products and quaternions.

Why HN likes it: HN calls it the best video on geometric algebra, one that makes the subject click in about 40 minutes.

“If you want an inspiring (imho) overview of the power of geometric algebra, I thoroughly enjoyed the video”
