In this video, I give an elegant solution to 3blue1brown's colliding block problem using linear algebra. More precisely, I first find the matrix A that encodes the whole process and show that we basically just need to find A^n, and I then do that by diagonalizing…

In 1995 I published an article in the Mathematical Intelligencer. This article was about giving the ultimate visual explanations for a number of stunning circle stacking phenomena. In today's video I've animated some of these explanations.

Here is a copy…

This is how the integrals were started!
We will be using n equal width right endpoint rectangles to approximate the area under y=x^3 from 0 to 1, then get the actual area. As a bonus, I will of course show you the integral way of doing this at the end. …
