The Elegant Universe, Part 1: Einstein's Dream (2003) | Full Documentary | NOVA | PBS

Video Description

"The Elegant Universe" 3-part-series will be available for the first time ever on YouTube. First premiering 20 years ago, this series is one of our most popular, and we are thrilled to make it accessible to a newer audience. These episodes will be lifted from the NOVA archives over the next few months. #NOVAPBS Official Website: https://to.pbs.org/3Yz4RKb Eleven dimensions, parallel universes, and a world made out of strings? It's not science fiction, it's string theory. Bestselling author and physicist Brian Greene offers a tour of this seemingly strange world in "The Elegant Universe," a three-part Peabody Award-winning miniseries. Part 1, "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.
