It’s exciting to see that Geometric Algebra is back on an upward path.
Grant Sanderson is 3Blue1Brown on Youtube, and he and others are inviting submissions for their “Summer of Math Education”. There’s a video about it at Why aren't you making math videos? (Also, a 3b1b podcast) - YouTube, but relevant links appear below the video (hit the “MORE” button). Deadline is August 22. Well, it’s a locked-down winter where I am, but I’m planning to do a submission.
My video will be “Geometric Algebra for High School”, and I’m hoping to concentrate on geometric understanding. If anyone is willing to review my submission before it goes in, then let me know.
Other folk might like to put in a more high-powered submission, which is more what they’re looking for.
