Lecture 1 | String Theory and M-Theory


StanfordUniversity asked:

(September 20, 2010) Leonard Susskind gives a lecture on the string theory and particle physics. He is a world renown theoretical physicist and uses graphs to help demonstrate the theories he is presenting. String theory (with its close relative, M-theory) is the basis for the most ambitious theories of the physical world. It has profoundly influenced our understanding of gravity, cosmology, and particle physics. In this course we will develop the basic theoretical and mathematical ideas, including the string-theoretic origin of gravity, the theory of extra dimensions of space, the connection between strings and black holes, the "landscape" of string theory, and the holographic principle. This course was originally presented in Stanford's Continuing Studies program.

    It’s incredible that such an intellectual powerhouse is contained in such a seemingly approachable person.

    @YawnGod The original “creators” of the graph didn’t really create it at all, they merely noticed the correlation of L to M^2 without knowing the reasons why. They came across it merely by observing, without knowing the mathematical cause. That’s why he calls them “lucky”. The next 1 1/2 hours were spent on him explaining those reasons. If you see him as bullying, that’s only because he’s short on time. He doesn’t have their cowardice, he has their respect, which he undoubtedly deserves.

    The first 5 minutes really gave me a negative first impression of this professor. He has a very dick-like douche bag quality about him. First the idea of gluons didn’t exist at the time. Then they did exist, but were not recognized or taken seriously. Then the creators of the graph of L to M^2 were lucky and stupid. But then later when challenged he recants and says they weren’t lucky nor stupid. If he’s trying to be funny, he’s failing, and he is being a bully, he does has their cowardice.

    that guy that talks around 4:37 has to say something in EVERY VIDEO. never a question but just some random statement about whatever Susskind is talking about at the moment like he wants everyone to know that he has some great understanding of what is being covered in lecture. SHUT UP and let him teach!

    “…including├»┬╗┬┐ following my own grandfather’s advice, which was whenever you give a talk to a thousand people about Richard Feynman, sustain yourself.”

    I can’t help but think about this watching professor Susskind’s lectures. =D

    Anyone else notice? Someone accidentally hit the thumbs down button. I assume it must have been a slip of the mouse.
