Volume 2 makes up a course in Advanced Quantum Mechanics and includes chapters on symmetry in physical laws, identical particles, symmetry and conservation laws, the hydrogen atom and the periodic table, and the Schrödinger equation in a classical context (this chapter also includes a seminar on superconductivity).
Don't miss any of Richard P. Feynman's engaging physics lectures.

The only way to follow these lectures is if you have the books
(ISBN 0-201--51003-0, 0-201-51004-9,0-201-501005-7) so you can follow the formulas and the diagrams.
However, the audio are all in just put together without a seeming order and you will have to buy all the audio volumes to follow the lectures in the order given in the books.
Vol 2 (audio) contains the following lectures.
Symmetry in Physical Laws (Vol. 1 Chapter 52 in the book)
Identical Particles (Vol 3 Chapter 4)
The Hyperfine Splitting in Hydrogen (Vol 3 Chapter 12)
Symmetry and Conservation Laws (Vol 3 Chapter 17)
The Hydrogen Atom and the Periodic Table (Vol. 3 Chapter 19)
The Schroedinger Equation in a Classical Context: A Seminar in Superconductivity (Vol 3 Chapter 21)
More delightful explanations of the weirdo quantum stuff from the master! If you haven't the hardcopy of the relevant lectures, or prior exposure to the math, then some of the board scribbling will sound rather foggy. If so, don't despair, close attention will still repay. Indistinguishable alternatives combine amplitudes. If Bose particles they add. If Fermi particles they subtract. So photons tend to aggregate - hence say, induced emission and lasers. Electrons tend to exclude - hence say, stability and chemical properties of matter. Remember that the wave/particle models are only useful guides to behaviour, depending on circumstance. The accuracy of quantum mechanics ( with respect to prediction of experiment ) comes using the math machinery as defined, and there's the rub. It's hard because it's not ( macroscopically/everyday ) intuitive, and at the end of the calculations one then has to obtain a physical interpretation. However Mr Feynman is a very helpful guide... and recall he said that nobody understands quantum mechanics!
It's true: large parts of this volume are impossible to follow. I've had a course in quantum mechanics and so I can understand parts of this volume. But the discussion on hyperfine splitting in the hydrogen atom is completely opaque without the boardwork.
You can still get the broad ideas, though, and Feynman's presentation is as charming as ever. So as a cultural/historical piece, it's fine. But don't expect to come away with a detailed understanding of the mechanics.
Without seeing what is being written on the board, these lectures are very difficult to understand, unless maybe you have already completed a similar course in a classroom setting. Many times things are written on the board with very little desciption of what is being written.
Hard to follow due to the fact that the lectures are in front of a blackboard and Mr. Feynman uses the blackboard to explain many of his key points. Would be a very good if it were video and the listener could see the blackboard. Without the visual, much of the audio is hard to follow.
The books and audios really go together ,the sound quality at times in this series is bad but it is 50years old and the audios don't match up with the chapters in the books if only the would clean up the sound and put the lectures in the orders with the riverside books as they were meant to be,that wold be heaven for serious students. But in spite of those flaws it's still beautifull
To me the study of atom and molecules,plus his discussion of quantum he should have been proud of thatp
Quantum and relativity always has an extreme reaction ,laugh?cry?no, amazed that such things are even possible would be more like it
