About The Book
The Principle of Least Action in Quantum Mechanics by Richard Feynman, edited by Laurie M. Brown, presents Feynman’s previously unpublished doctoral thesis, which became a cornerstone of his remarkable contributions to theoretical physics. Feynman’s thesis, originally focused on quantizing classical electrodynamics, adopted a new approach to quantum theory by using the Lagrangian function and the principle of least action, thus giving rise to the path integral formulation. This path integral approach has not only shaped quantum mechanics but also led to the development of Feynman diagrams, essential in the field of quantum field theory.

The book also includes Feynman’s related review article “Space-Time Approach to Non-Relativistic Quantum Mechanics,” Paul Dirac’s seminal work on the Lagrangian in quantum mechanics, and an insightful introduction by Laurie M. Brown. Feynman’s thesis, with its innovative space-time perspective, has applications across a wide range of areas, including quantum field theory, statistical mechanics, atomic and molecular scattering, and Brownian motion, offering new insights into the interpretation of quantum theory. This volume is an indispensable resource for physicists and students seeking to understand the foundational work that influenced much of modern physics.math
