Nova | The Elegant Universe

"The fundamental particles of the universe that physicists have identified—electrons, neutrinos, quarks, and so on—are the "letters" of all matter. Just like their linguistic counterparts, they appear to have no further internal substructure. String theory proclaims otherwise. According to string theory, if we could examine these particles with even greater precision—a precision many orders of magnitude beyond our present technological capacity—we would find that each is not pointlike but instead consists of a tiny, one-dimensional loop. Like an infinitely thin rubber band, each particle contains a vibrating, oscillating, dancing filament that physicists have named a string."

All three hours of this popular mini-series are now viewable online! You'll need Quicktime or a Realplayer alternative (I don't recommend Realplayer) like Real-Alternative to view. Worth every minute - a definite must-see.
