Feynman Lectures on Tuva

Bill Gates bought the rights to a series of lectures by Richard Feynman called "The Character of Physical Law". And now they're available for free online!

I've heard, of course, of the legend that is Feynman, but this is the first time I've actually cared to look into it. Now that I've seen him, he's a great lecturer for sure. Though the lectures are on the basic, general level, they say things that even I've never thought about.

So far, my favorite lecture is number 2, "The Relation of Mathematics and Physics". He even goes so far as to refer to Lagrangian Mechanics as a mathematical alternative to Newtonian Mechanics or field mechanics. That makes anyone awesome in my book.
