Here’s another geometric algebra video, weighing in at a massive 2:29 (minutes.)

This video is a very short introduction to geometric algebra, showing the most basic concepts and how to apply them to the 2D geometric algebra of the Euclidean plane. Those concepts aren’t developed further in this video, but the idea is just to show the most basic consequences of the definitions.

Prerequisites: basic vector algebra (basis, vector space, dot product space, arrow representation of vectors, graphical vector addition, …)

If you watched yesterday’s video, don’t both watching this one, since it is extracted from that with no additions.

You can find the video on Google’s censorship-tube, and on odysee.
