(January 24, 2011) Leonard Susskind uses the most complex math that will be used in the course with the hopes that it will give a better idea of how a black whole works mathematically. 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.
