This text concerns continuum mechanics, electrodynamics and the mechanics of electrically polarized media, and gravity. Its accessible approach formulates theories according to the principle of least action, a concise method that makes the physical content of classical subjects intelligible to advanced undergraduates and graduate students. 1976 edition.
