Richard Phillips Feynman (/ ˈ f aɪ n m ə n /; May 11, 1918 – February 15, 1988) was an American theoretical physicist.He is best known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, the physics of the superfluidity of supercooled liquid helium, and in particle physics, for which he proposed the parton model.
The Meaning of It All: Thoughts of a Citizen Scientist is a non-fiction book by the Nobel Prize-winning physicist Richard Feynman. It is a collection of three previously unpublished public lectures given by Feynman in 1963. [1] The book was first published in hardcover in 1998, ten years after Feynman's death, by Addison–Wesley.
The original motivation stemmed from the desire to obtain a quantum-mechanical formulation for the Wheeler–Feynman absorber theory using a Lagrangian (rather than a Hamiltonian) as a starting point. These are five of the infinitely many paths available for a particle to move from point A at time t to point B at time t’(>t).
The names of action principles have evolved over time and differ in details of the endpoints of the paths and the nature of the variation. Quantum action principles generalize and justify the older classical principles. Action principles are the basis for Feynman's version of quantum mechanics, general relativity and quantum field theory.
Perfectly Reasonable Deviations from the Beaten Track: The Letters of Richard P. Feynman is a collection of Nobel Prize winner Richard Feynman's letters. [ 1 ] [ 2 ] [ 3 ] The book was edited by his daughter, Michelle Feynman , and includes a foreword by Timothy Ferris .
The Feynman Lectures on Physics is a physics textbook based on a great number of lectures by Richard Feynman, a Nobel laureate who has sometimes been called "The Great Explainer". [1] The lectures were presented before undergraduate students at the California Institute of Technology (Caltech), during 1961–1964.
A Feynman diagram is a graphical representation of a perturbative contribution to the transition amplitude or correlation function of a quantum mechanical or statistical field theory. Within the canonical formulation of quantum field theory, a Feynman diagram represents a term in the Wick's expansion of the perturbative S-matrix.
Feynman's comments on the reliability of the shuttle, published as an appendix to the Rogers Commission's final report, are included. The second section of the book was dramatized in a television movie by BBC/Science Channel titled The Challenger Disaster. The book is much more loosely organized than the earlier Surely You're Joking, Mr. Feynman!
