3Blue1Brown
Videos and explanations of some of the most fascinating concepts within math.
From the official website:
“3blue1brown, or 3b1b for short, is primarily a YouTube channel about discovery and creativity in math. On this site, you can find written versions of many of these lessons, often with more interactive elements sprinkled in.
Topics tend to fall into one of two categories:
- Those people might be seeking out, like linear algebra, neural networks, calculus, Fourier transforms, quantum mechanics, etc.
- Problems in math which many people may not have heard of, and which seem quite challenging at first, but where some shift in perspective makes it both doable and beautiful.
Loosely speaking, the first category motivates math by its usefulness, and the second motivates math as an art form. But of course, the line dividing these two is easily blurred.”
