Lecture 8 of Leonard Susskind's course on Cosmology. Recorded March 16, 2009 at Stanford University.

This Stanford Continuing Studies course is the fifth of a six-quarter sequence of classes exploring the essential theoretical foundations of modern physics. The topics covered in this course focus on classical mechanics. Leonard Susskind is the Felix Bloch Professor of Physics at Stanford University.

  • Whoa! Unexpected change of venue. After watching this series of lectures I'm almost uncomfortable seeing him in front of a board that's not white ;)

    Much respect for Dr. Susskind.

  • As Leonard Susskind said in another set of lectures, "The final exam is buying me lunch".

    :)

  • Statistical Mechanics is the 6th portion of this series of lectures for anyone who was wondering.

  • muddled mess.

  • this scalar field business barely deserves the label of an explanation

  • One of these days he's going to forget which hand has the chalk and which hand has the cookie O:

  • This is simply great! Nice lecture video.

  • Where does 10^(-123) come from? Since 10^(-123) ~ 2^(-408) and there may be 408 types of particles in the universe. Given one of each particle in order in a line with random spin what is the probability that each will have spin-up? Answer 10^(-123).

    Obviously this is contrived but goes to show how the number could come from combinatorial principles and probabilities.

  • A example of an formula which matches the instanton potential curve V(rho) described might be:

    rho_0 + phi^2

    ------------------

    1 + phi^2

    in units where rho_0 is small compared to 1. This curve is almost flat except in the middle where it dips sharply to rho_0.
