The Elegant Universe Science Documentary hosted by Brian Greene, published by PBS - English narration Information ------------------------------ Nova: The Elegant Universe Physicist Brian Greene's bestselling book comes to the small screen in this stimulating look at a complicated topic: the search for order in the universe. Is a revolutionary proposal--"string theory"--the answer scientists have been seeking for centuries? Greene tackles the mind-boggling complexity of the theory with vivid, clear images, and calmly points the way to the answer 1) Einsteins Dream "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. 2) Strings the Thing "String's the Thing," opens with a whimsical scene in a movie theater in which the history of the universe runs backwards to the Big Bang, the moment at which general relativity and quantum mechanics both came into play, and therefore the point at which our conventional model of reality breaks down. Then it's string theory to the rescue as Greene describes the steps that led from a forgotten 200-year-old mathematical formula to the first glimmerings of strings-quivering strands of energy whose different vibrations give rise to quarks, electrons, photons, and all other elementary particles. Strings are truly tiny, being smaller than an atom by the same factor that a tree is smaller than the solar system. But, as Greene explains, they are able to combine the laws of the large and the laws of the small into a proposal for a single, harmonious theory of everything. 3) Welcome to the 11th Dimension Part 3 of "The Elegant Universe" with host Brian Greene shows how Edward Witten of Princeton's Institute for Advanced Study, aided by others, revolutionized string theory by successfully uniting the five different versions into a single theory that is cryptically named "M-theory," a development that requires a total of eleven dimensions. Ten...eleven...who's counting? But the new 11th dimension implies that strings can come in shapes called membranes, or "branes" for short. These have truly science fiction-like qualities, since in principle they can be as large as the universe. A brane can even be a universe-a parallel universe-and we may be living on one right now. Witten has described string theory as "a part of 21st-century physics that fell by chance into the 20th century." In fact, the theory is so far ahead of experimental technique that there is as yet no way to verify whether strings are real. But scientists at the CERN atom-smasher on the French-Swiss border are working to test of one of the predictions of string theory. This experiment may take an important step in showing that string theory is not just a crazy idea, but crazy reality.

With the number of space related TV shows I have been watching recently I should enroll in an OU astrophysics course, maybe then I'll be able to grasp some of the mind boggling concepts in quantum mechanics. |

Ahhh... you'd think so, but I bet you'd end up even more confused, but with a degree in it! |

Pretty sure I downloaded this yonks ago, the elegant universe rings a bell and it was about the same topic. Or did I... Damn quantum physics.. Oh well, can't hurt to watch it again and with my brain it'll be like watching it for the first time anyway!! |

ye this is old 2003 and i think i have seen it before, if i remember correctly the last part is about string theory and stuff so just remember that is not fact like the other parts, quantum and relativity, i think Brian Greene got some criticism whit his new book that he keeps on selling this string stuff but for all these years there is no evidence at all for it , so it might just be alotta bull =) but i still watch his new show on pbs , i need my pop sci fix!! =) |

All true. Strings' only claim to fame as an alternative to quantum gravity seems to be how "pretty" or elegant the multi-dimensional math is- which means zippity as far as I'm concerned. Still, 1st 2 parts are solid and the 3rd part is interesting enough with segments on the universal constants for our universe and what it might mean for that to be just a brane within a 'loaf'. I bought the set on DVD when it was on sale 2 years ago. |
