www.ted.com/ In clear, nontechnical language, string theorist Brian Greene explains how our understanding of the universe has evolved from Einstein's notions of gravity and space-time to superstring theory, where minuscule strands of energy vibrating in 11 dimensions create every particle and force in the universe. (This mind-bending theory may soon be put to the test at the Large Hadron Collider in Geneva).

    I have a lot of respect for this guy. His ability to explain things in a way that allows you to really understand and not seem so abstract is a sign of true intelligence I think.. his books are even better
  • @giuseppe3010
    The signature of a good teacher is his/her ability to explain very well what he is teaching. Brian Greene has that signature!
  • I think Brian's ability to communicate such concepts is awesome.
  • @guydreamr
    Great speaker and his book "The Elegant Universe" is legendary.
  • @mickeypopa
    Fast forward 15 years and still nothing, jury is still out.
  • @joedoe783
    I've watched many videos on string theory but this is the first time I think I've grasped it. This guy is an excellent communicator.
  • Brian Greene is my favorite, love to listen him, and he always demonstrate thing visually.Easy to learn from him. Very educational.
  • He's such a good writer; I had no idea he was also such a good speaker. Best of luck to those guys. Whether you think string theory is a valid enterprise or not, someone has to prove it either way, which is what they're doing. If they're right... what a discovery. If they're wrong... what a discovery.

    Sometimes when I start to think I'm really smart I like to watch stuff like this to keep my ego grounded.
  • @Boogieplex
    Brian Greene is the total package. He’s a brilliant mathmatician,theorist,physicist,cosmologist,scientist all with the ability to explain things that would be otherwise impossible to understand. I remember watching “the elegant universe “ as a kid and being blown away.
  • @whoisray1680
    I can keep listening to him forever without getting tired of it and still understand all of it
  • @AlpNewYork
    I can only show two dimensions on the screen but some of you guys will fix that some day :)
  • @fortuner123
    Excellent. Very easy to understand with his perfect delivery.
  • What we must always remember is that when we find the answer to the meaningful we realize how little later we know. What makes times so special as to be one and absolute? There’s always more, let’s all work together in unity and love
  • @ZaChYmO
    Still after almost 2 decades, the best string theory Beautifully explained by Dr. Brian Greene
  • @Lo2y
    The best explanation of string theory ever ❤️
  • @sharinglanguage
    This is a fantastic summary of his book: "The elegant universe"
  • @fawnwoods6123
    I'm grateful for his talks, because his books are over my head.

    Its going to be a breakthrough when we prove the existence of other dimensions with particle collision and converge the ideas and theories of every scientific genius. To know we are one collision away just makes it that more exciting . We found the higgs boson particle now onward to the graviton !! Love this TED talk btw !! Very smart man.
