Essential Physics, Part 1: Relativity, Particle Dynamics, Gravitation and Wave Motion

The first chapter contains key mathematical ideas, including some invariants of geometry and algebra, generalized coordinates, and the algebra and geometry of vectors. The importance of linear operators and their matrix representations is stressed in the early lectures. These mathematical concepts are required in the presentation of a unified treatment of both Classical and Special Relativity. Students are encouraged to develop a “relativistic outlook” at an early stage. The fundamental Lor...
