NOVA - The Elegant Universe - PBS

Eleven dimensions, parallel universes, and a world made out of strings. It's not science fiction, it's string theory. One of the most ambitious and exciting theories ever proposedone that may be the long-sought "theory of everything," which eluded even Einsteingets a masterful, lavishly computer-animated explanation from bestselling author-physicist Brian Greene, when NOVA presents the nuts, bolts, and sometimes outright nuttiness of string theory. Also known as superstring theory, the startling idea proposes that the fundamental ingredients of nature are inconceivably tiny strings of energy, whose different modes of vibration underlie everything that happens in the universe. The theory successfully unites the laws of the largegeneral relativityand the laws of the smallquantum mechanicsbreaking a conceptual logjam that has frustrated the world's smartest scientists for nearly a century.
