Lecture 5 | String Theory and M-Theory

(October 18, 2010) Professor Leonard Susskind delivers a lecture concerning plonck variables and how they relate to string theory in the context of modern physics.

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 Professor Leonard Susskind delivers a lecture concerning plonck variables and how they relate to string theory in the context of modern physics.

" The stiffer they are, the smaller they are "...I'm glad that's not true for everything :P

Great respect to the great Susskind, but you really cannot throw away infinities as readily as he would like.

59:30 Is John Goodman in this class??

@ugowar Plunk.

thank you very much to make me understand

Very cute and (even for me) understandable explanation of the D = 26 for bosonic strings.

And he was SO funny again; just cant get enough of these lectures :-) ...

@theJtot It's a continue education course - people who've graduated. It can be taken by anyone. From what I gather, it's mostly people who've been out of school for a while take it (~30-40 years), some retired, of various background. Thus the simple math.

I have to wonder what level students he's teaching...i took complex variables in my second year

i had thought these were PhD students

but i find it hard to imagine that he would have to ask PhD students to go prepare for complex analysis

@dragonograd Of course, it only feels that way.
