Feynman's Thesis: A New Approach to Quantum Theory,New
Delivery time: 8-12 business days (International)
Richard Feynmans never previously published doctoral thesis formed the heart of much of his brilliant and profound work in theoretical physics. Entitled 'The Principle of Least Action in Quantum Mechanics,' its original motive was to quantize the classical actionatadistance electrodynamics. Because that theory adopted an overall spacetime viewpoint, the classical Hamiltonian approach used in the conventional formulations of quantum theory could not be used, so Feynman turned to the Lagrangian function and the principle of least action as his points of departure.The result was the path integral approach, which satisfied and transcended its original motivation, and has enjoyed great success in renormalized quantum field theory, including the derivation of the ubiquitous Feynman diagrams for elementary particles. Path integrals have many other applications, including atomic, molecular, and nuclear scattering, statistical mechanics, quantum liquids and solids, Brownian motion, and noise theory. It also sheds new light on fundamental issues like the interpretation of quantum theory because of its new overall spacetime viewpoint.The present volume includes Feynmans Princeton thesis, the related review article 'SpaceTime Approach to NonRelativistic Quantum Mechanics' [Reviews of Modern Physics 20 (1948), 367 387], Paul Diracs seminal paper 'The Lagrangian in Quantum Mechanics [Physikalische Zeitschrift der Sowjetunion, Band 3, Heft 1 (1933)], and an introduction by Laurie M Brown.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
