Lecture 4 | Topics in String Theory

(January 31, 2011) Leonard Susskind gives a lecture on string theory and particle physics that focuses on the geometry of a black hole near the horizon. He describes how standard concepts from quantum physics can explain the physics that occur at this point.

In the last of course of this series, Leonard Susskind continues his exploration of string theory that attempts to reconcile quantum mechanics and general relativity. In particular, the course focuses on string theory with regard to important issues in contemporary physics.

This course was originally presented in Stanford's Continuing Studies program. Leonard Susskind is the Felix Bloch Professor of Physics at Stanford University.

Hi guys, I am a psych grad and I am grateful to Stanford for posting knowledge online. So recently, I have started my own lecture series on Psychology, Behavioral Science. do check out my channel if you are interested!

Great video. This is a wonderful lecture to listen at.

It seams time invariant equations would mean that if a thing happens, then (time being one dimension) to go backwards would simply be to undo (and unlearn) what had happened. Alice comes out, but neither of them remember her going in to begin with. No? Sorry if I'm just stupid and/or confused :n)

what is string theory

[cloffff]

@mccdotedu Feynman has been dead since the 1980s.

nice of him to represent feynman since feynman openly ridicules string theory

thank you!!!! i have told people that when we see something we are viewing it in the past relative to the person.... i just wish i knew the math to explain it...

you make me wanna cookie...

@GunsNRosesbitches ah alright :)
