I’ve tried five different times to understand quaternions; I’ve shipped production code to hundreds of millions of devices involving them 👹, and I *still* don’t get them 😓. Well, didn’t!—this is the first time I’ve really understood. 👏

It’s here! Quaternions: youtu.be/d4EgbgTm0Bg “But Grant, 30 minutes seems like a bit much to set aside right now.” Pssht, don’t give me that, I saw you on Netflix last night.

Thanks so much Andy!

Actually, what was the production code your referencing? Maybe this would make a good example for the follow-on video...

Same here! I know how to do the magic, know when and how to use it, but could never wrap my head quite around it.

Serious question. Twitter isn't searchable at all in any meaningful fashion. Do you blog or post links elsewhere?

I blog intermittently on my research at medium.com/khan-academy-e and other things at blog.andymatuschak.org, but it's a much lower volume. I acknowledge the weakness of the medium! Thanks for being interested.
