Geometric algebra: a very short video introduction.

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:…

second experiment in screen recording

Here’s a second attempt at recording a blackboard style screen recording:

  To handle the screen transitions, equivalent to clearing my small blackboard, I switched to using a black background and just moved the text as I filled things up.  This worked much better.  I still drew with mischief, and recorded with OBS, but then did a…

experiment in screen recording: An introduction to Geometric Algebra.

I’ve been curious for a while what it would take to create lesson style screen recordings, and finally got around to trying one myself:

  This is an introduction to Geometric (Clifford) algebra.  I briefly outline a geometrical interpretation of various products of unit vectors, rules for reducing products of unit vectors, and the…
