Classical Field Theory and the Stress-Energy Tensor (Second Edition) is an introduction to classical field theory and the mathematics required to formulate and analyze it. The development of the mathematical formalism, previously in an appendix, is integrated into the presentation of the physical concepts. The book develops the core concepts of field theory by applying Newtonian physics to the stretched string, emphasizing the relationship between fields and the observer's coordinate systems and using basic concepts of differential geometry and functional techniques. This collection of insights should be invaluable to both the student, instructor, and active researcher since it presents a unified view of field theories without the added complication of quantization.

Key Features

This is a self-contained and compact introduction tothe derivation and methods of path integral approaches to quantum mechanics andquantum field theory. The necessary background mathematics as well asillustrative examples are included.

This extended and updated second edition course text presents a logical and concise introduction to the basic concepts, applications, and physical meaning of quantum mechanics. An initial review of classical mechanics and electromagnetism provides the reader with the context for quantum mechanics. Starting with atomic level experimental results, the probabilistic nature of quantum mechanics is derived, with the wave function related to the statistical theory of random variables. Applying the requirement of Galilean invariance yields the Schrodinger equation, and the Copenhagen interpretation of the wave function is discussed. After numerous basic applications of wave mechanics, including the hydrogen atom and the harmonic oscillator, the text then presents Dirac notation and Hilbert space theory. New chapters discuss perturbation theory, path integrals, scattering theory, and quantum entanglement.
