Lecture 7 of Leonard Susskind's Modern Physics course concentrating on Classical Mechanics. Recorded November 26, 2007 at Stanford University.

This Stanford Continuing Studies course is the first 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.

    Isn't the area remaining constant in phase space, another way of saying that the total energy of a collection of systems remains constant....?

    Professor Suskind.Guess his one of a kind.One of a few Hardcore physics lecturer in our country today.

    Nvm that, the whole L = T-V thing is a mnemonic. I was just reading about this in Shankar and the EM Lagrangian he uses is correct. For more info check "R. Shankar - Principles of QM, page 83".

    At about 1:43, he actually gets -Bx and -By. My guess is that when he set up the Lagrangian he put +V instead of -V for the potential, in this case magnetic vector potential. So he ends up with -(v x B) instead of (v x B).

    It'll be nice if someone can confirm this.

    He's not talking about localizing a particle's position in space, but its simultaneous position and momentum in phase space. A minimum phase space area of hbar implies delta p * delta q >= hbar, which is basically just a geometric interpretation of the Heisenberg uncertainty principle. Why he writes hbar instead of hbar / 2 for the area is unclear to me, but it may just be a simplification.

    I am studying Physics in Germany and this lecture helped me a lot! I can't find any electrodynamics Lecture. He didn't give one? :(
