More linear algebra quizzes. Cramer's rule is a neat trick for solving equations, and for understanding inverse matrices. Understanding the geometry behind it is a great workout for testing your geometric intuitions of L.A.

One of my goals this year is to invest in translations for 3blue1brown. I’d like to hire translators directly, preferably ones with experience teaching, and who are willing to help experiment with some software tools which I hope can make the process less tedious.

For early experiments, we’re budgeting for five languages (Arabic, French, German, Spanish, Hindi). If you’re interested in helpin3Blue1BrownPost · 2 months ago
I'd like to share some music from the channel's regular composer, Vince Rubinetti, for a project never (yet) made: https://vincerubinetti.bandcamp.com/a...
I spent an embarrassingly large amount of mindshare in 2021 and 2022 researching the story of Évariste Galois, and began to assemble a large video about it. The end of of the story is quite famous to those who study math: He died in a duel at 20 years old, preceded by a night frantically compiling notes representing some of the first steps into group t3Blue1BrownPost · 3 months ago
