Brian Greene's Very Elegant Universe
NOVA | The Elegant Universe | PBS
One of the most fascinating science programs I have ever seen. I first heard of it about a year ago, and I have gone back to rewatch it at least five times since then with friends. Brian Greene, Columbia University physicist and "string theorist" presents very complex concepts in an easily comprehended manner, using very creative teaching techniques and entrancing digital graphics. When you finish the roughly three hour documentary you will find yourself waiting in eager anticipation of scientific break-throughs in things you had never previously heard of, like "super-symmetry" and the "graviton". It is an absolute must-watch, and best of all-- it is totally free.
