This is the boxed set of physics textbooks based upon the lectures of renowned physicist Richard P. Feynman. Originally delivered to California Institute of Technology undergraduate students from 1961 to 1963, the lectures were made famous due to Feynman’s penchant for teaching complex concepts using easy-to-understand language, which earned him the moniker “The Great Explainer” by his contemporaries. Spanning three volumes and 115 chapters, Feynman explains how the perpetual motion of atoms attracting and repelling one another amounts to “jiggling”—faster jiggling equates to heat while slower jiggling equates to cold. He later uses the layer of dust on a fast-moving fan blade in volume II to explain how the velocity of a fluid (air) is exactly zero at the surface of a solid (fan blade).
