The Elegant Universe. Einstein's Dream

Description

This program introduces string theory and shows how modern physics - composed of two theories that are ferociously incompatible - reached its schizophrenic impasse. One theory, general relativity, successfully describes the stars and galaxies, while another, quantum mechanics, is equally successful at explaining small things like atoms and subatomic particles. Albert Einstein, the inventor of general relativity, dreamed of finding a single theory that would embrace all of nature's laws. But in this quest for the so-called "unified" theory, Einstein came up empty-handed, and the conflict between general relativity and quantum mechanics has stymied all who've followed. That is, until the discovery of string theory.
