Interesting Lectures - Part 3

So this amazingly long running two part series finally continues with a third piece!

Continuing from the last part is part 10/27 from Richard A. Muller's Physics for future Presidents course at UC Berkely, and this particular one is on Gravity and Satellites. Almost all the physics here is pretty basic, but is laid out in such a way as to make it easy to understand the concepts involved. Richard Muller does it particularly well, and even if you're already aware of everything contained therein, it's still an enjoyable watch.
