The next series of YouTube lessons will be on Einstein’s Theory of Relativity. Loosely based on the Summer School series of the same name, I’ll be covering the Special and General theories. I won’t be posting with every update, though: I plan to break the original nine lessons up into a larger number of smaller videos. I’ll periodically update with links to the playlist once a batch of lessons are complete. The introductory lesson (which ends with a link to that playlist) is included below.
