Lecture 9 | String Theory and M-Theory

(November 23, 2010) Leonard Susskind gives a lecture on the constraints of string theory and gives a few examples that show how these work.
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.

No no,

no no no no,

no no no no,

no no there's no limit!

@Engravingsful > String theory are superstition

A stunningly ignorant statement.

[grunder20]

Really didnt understand what M theory is.

Prof. Susskind seems not to be a fan of his colleagues doing F-theory, they have 10 space and 2 time (alltogether 12 !) dimensions LOL :-D ...

"If you want to know the future history of it..."

[csmcmillion]

"and take it, to the limit, one more time."

[agapitoflores001]

This is just so informative. It's as if I'm in Stanford.

[euroroomer]

i am literally amazed such a university and such a professor of such caliber would offer this...for free. Tale about a commitment to education!

@superok4luv2u sorry the e8 dig was out of context since the theorys still not past 1st level fermions its incomplete and therefore unfalsifiable :)
