The GAME2020 event (Geometric Algebra Mini Event) showcased applications in graphics, physics, robotics, neural networks, mathematics. The lectures (from Cambridge, UVA, UPEM, TU Delft, ..) are all available here : https://www.youtube.com/playlist?list=PLsSPBzvBkYjzcQ4eCVAnt...

"Mini Event" = several 1 hour long talks

Was hoping for more (time wise) digestible introductions.

There have been attempts to use it in physics, mainly as a way of unifying the various formalisms that get used there: http://geocalc.clas.asu.edu/html/Overview.html

From a paper (out of a quick google search) [1]:

* neural computing

* image and signal processing

* computer and robot vision

* control problems

I have also seen some work on doing collision checking for robot arm kinematics -- which is a rather nasty problem when done the traditional way.

[edit to add] Also all the classic RF transmission line problems that one would normally solve with Smith Chart techniques map fairly elegantly onto GA(2)
