Perseus is proud to announce the release of the next two volumes in the complete collection of audio recordings of Feynman's famous Caltech course from which his classic textbook, Lectures on Physics, was produced.

These fifth and sixth volumes in the collection comprise Feynman on Fundamentals. Volume 5 makes up a beginning course in Energy and Motion, and includes chapters on the conservation of energy, motion, Newton's laws of dynamics, the conservation of momentum, and work and potential energy. Volume 6 makes up a course in Kinetics and Heat, and includes chapters on the kinetic theory of gases, brownian motion, applications of kinetic theory, diffusion, the laws of thermodynamics, and illustrations of thermodynamics.
