Link to The elegant universe: 1- Einsteins dream documentary
Documentary Description
"Einstein's Dream," 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 big things like 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.
