I am usually amazed twice by 3B1B videos. First by the way he presents the material, then by the fact that I've never seen it presented anything like the way he did it. While I'm no mathematical scholar, I have read and re-read a lot of "basic" linear algebra and calculus. Usually choosing a different source every time I have to go back and re-read it. And I've never come across anything that does as good as his series on those two subjects. Granted, I'll still forget the material since I don't use it every day. But I do believe it gave me a deeper insight, and will help me remember it longer.
