Lecture 10 | String Theory and M-Theory

(November 30, 2010) Professor Leonard Susskind continues his discussion on T-Duality; explains the theory of D-Branes; models QFT and QCD; and introduces the application of electromagnetism.

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.

Good, I like that you share this video, I wish success always is the basis for the most ambitious theories of the physical world

Wow, Leonard Susskind !

The field of D- brane dynamics may no longer be in its infancy, it may be passing a turbulent adolescence time. Let us hope it will arrive at a successful and productive mature life.

Ha ha, now I`ve see all 10 of them :-D

As Lenny Susskind says, You can call me g55 LOL

Many happy thanks for this GREAT course

This is such a privilege. Fight tooth and nail to keep these lectures on youtube. This is a type of video that is all too rare.

thanks for sharing

[thebigfootme]

thanks for the lecture..nice one!

[agapitoflores001]

I think I already watched this video. Might be a duplicate..Or I guess just a continuation..

[FMMAROTO]

Thanks. I couldn't stop watching!

I think it's important to note that, like quantum mechanics, NOBODY truly understands it. As Feynman once explained, we know how to DO quantum mechanics, and we know how to DO string theory, and that's all very well and perhaps these little strings really are the fundamental particles of our universe, but even so that doesn't change the fact all those important "why" questions completely elude us and perhaps always will. String theory being correct has much fewer implications than people assume.

@luzzie9 I don't think you'll like hearing this but to get to the point where you understand the motivation for string theory, you'll need a graduate level understanding of math and basic physics, and yes, also a bit of imagination.
