The Elegant Universe: It's String Theory

is a 3-hour miniseries exploring one of the most ambitious theories ever proposed: the "theory of everything." String theory proposes that the fundamental ingredients of nature are tiny strings of energy whose different modes of vibration underlie everything that happens in the universe. It unites the laws of general relativity and quantum mechanics, breaking a logjam that has frustrated scientists for nearly a century. Watch all 3 hours online.

Interesting Fact:

An early attempt to explain the concept of extra dimensions came in 1884 with the publication of Edwin A. Abbott's Flatland: A Romance of Many Dimensions. This novel is a "first-person" account of a two-dimensional square who comes to appreciate a three-dimensional world.
