These two volumes in the collection comprise a complete course on matter:
Volume 3: From Crystal Structure to Magnetism includes chapters on the internal geometry of crystals, the refractive index of dense materials, elastic materials, dielectrics, and magnetism.
Volume 4: Electrical and Magnetic Behavior includes chapters on propagation in a crystal lattice, semiconductors, the independent particle approximation, the Schrodinger equation in a classical context, superconductivity, paramagnetism and magnetic resonance, and ferromagnetism.
Richard Phillips Feynman was an American theoretical physicist known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, and the physics of the superfluidity of supercooled liquid helium, as well as in particle physics for which he proposed the parton model. For his contributions to the development of quantum electrodynamics, Feynman, jointly with Julian Schwinger and Sin-Itiro Tomonaga, received the Nobel Prize in Physics in 1965. - Wikipedia
