Basic Books is proud to announce the first volumes of the complete audio CD collection of the recorded lectures delivered by the late Richard P. Feynman, lectures originally delivered to his physics students at Caltech and later fashioned by the author into his classic textbookLectures on Physics. Ranging from the most basic principles of Newtonian physics to such formidable theories as Einstein's general relativity, superconductivity, and quantum mechanics, Fenyman's lectures stand as a monument of clear exposition and deep insight.
