The Character Of Physical Law A Series Of Lectures Etc

A series of classic lectures, delivered in 1960 and recorded for the BBC. This is Feynman's unique take on the problems and puzzles that lie at the heart of physical theory - with Newton's Law of Gravitation; on whether time can ever go backwards; on maths as the supreme language of nature. Demonstrates Feynman's knack of finding the right everyday illustration to bring out the essence of a complicated principle - eg brilliant analogy between the law of conservation energy and the problem of drying yourself with wet towels. 'Feynman's style inspired a generation of scientists. This volume remains the best record I know of his exhilarating vision' - Paul Davies

The Concept of Physical Law is an original and creative defense of the Regularity theory of physical law, the concept that physical laws are nothing more than descriptions of whatever universal truths happen to be instanced in nature. Prof. Brooks identifies and analyzes the arguments and intuitions of the opposing Necessitation theory, and argues that the standard objection to the Regularity theory turns on a mistaken view of what Regularizes mean by 'physical impossibility'; that it is impossible to construct an empirical test that can distinguish between events Necessitations call 'mere accidents' and those they call 'neurologically necessary', and that the Necessitation theory cannot account for human beings' free wills. It is strange, but on the rare occasions when I have been invited to play the drum in public,1the presenter never thought it necessary to remember that I also deal with theoretical physics. Maybe it's because we respect the arts more than the sciences. Renaissance artists used to say that man's primary interest must be man: however, there are other interesting things in the world, and even artists appreciate sunsets, ocean waves and the walk of the stars across the skies. So there are good reasons to sometimes talk about something else as well. When we look at the beauties of nature, we derive an aesthetic pleasure from direct observation. Among the phenomena of nature, however, there is also a structure, a rhythm that does not appear directly to the eye, but that is revealed only after a more careful analysis; and it is these rhythms and structures that we call physical laws. What I want to discuss in this series of lectures is the general feature of physical laws; if you will, this is a higher level of generality that is above the laws themselves. More precisely, what I want to consider is nature and its more general qualities as they appear on detailed analysis. Now, such a subject has a certain tendency to become too philosophical precisely because it becomes so general: when it is spoken in such general terms that everyone can understand, then the subject is considered profound philosophy. I would like to be a little more.

An introduction to modern physics and to Richard Feynman at his witty and enthusiastic best, discussing gravitation, irreversibility, symmetry, and the nature of scientific discovery. Richard Feynman was one of the most famous and important physicists of the second half of the twentieth century. Awarded the Nobel Prize for Physics in 1965, celebrated for his spirited and engaging lectures, and briefly a star on the evening news for his presence on the commission investigating the explosion of the space shuttle Challenger, Feynman is best known for his contributions to the field of quantum electrodynamics. The Character of Physical Law, drawn from Feynman's famous 1964 series of Messenger Lectures at Cornell, offers an introduction to modern physics—and to Feynman at his witty and enthusiastic best. In this classic book (originally published in 1967), Feynman offers an overview of selected physical laws and gathers their common features, arguing that the importance of a physical law is not “how clever we are to have found it out” but “how clever nature is to pay attention to it.” He discusses such topics as the interaction of mathematics and physics, the principle of conservation, the puzzle of symmetry, and the process of scientific discovery. A foreword by 2004 Physics Nobel laureate Frank Wilczek updates some of Feynman's observations—noting, however, “the need for these particular updates enhances rather than detracts from the book.” In The Character of Physical Law, Feynman chose to grapple with issues at the forefront of physics that seemed unresolved, important, and approachable.

The Feynman Lectures on Gravitation are based on notes prepared during a course on gravitational physics that Richard Feynman taught at Caltech during the 1962-63 academic year. For several years prior to these lectures, Feynman thought long and hard about the fundamental problems in gravitational physics, yet he published very little. These lectures represent a useful record of his viewpoints and some of his insights into gravity and its application to cosmology, superstars, wormholes, and gravitational waves at that particular time. The lectures also contain a number of fascinating digressions and asides on the foundations of physics and other issues.Characteristically, Feynman took an untraditional non-geometric approach to gravitation and general relativity based on the underlying quantum aspects of gravity. Hence, these lectures contain a unique pedagogical account of the development of Einstein's general theory of relativity as the inevitable result of the demand for a self-consistent theory of a massless spin-2 field (the graviton) coupled to the energy-momentum tensor of matter. This approach also demonstrates the intimate and fundamental connection between gauge invariance and the principle of equivalence.

One of the most famous science books of our time, the phenomenal national bestseller that "buzzes with energy, anecdote and life. It almost makes you want to become a physicist" (Science Digest). Richard P. Feynman, winner of the Nobel Prize in physics, thrived on outrageous adventures. In this lively work that “can shatter the stereotype of the stuffy scientist” (Detroit Free Press), Feynman recounts his experiences trading ideas on atomic physics with Einstein and cracking the uncrackable safes guarding the most deeply held nuclear secrets—and much more of an eyebrow-raising nature. In his stories, Feynman’s life shines through in all its eccentric glory—a combustible mixture of high intelligence, unlimited curiosity, and raging chutzpah. Included for this edition is a new introduction by Bill Gates.

Many appreciate Richard P. Feynman's contributions to twentieth-century physics, but few realize how engaged he was with the world around him -- how deeply and thoughtfully he considered the religious, political, and social issues of his day. Now, a wonderful book -- based on a previously unpublished, three-part public lecture he gave at the University of Washington in 1963 -- shows us this other side of Feynman, as he expounds on the inherent conflict between science and religion, people's distrust of politicians, and our universal fascination with flying saucers, faith healing, and mental telepathy. Here we see Feynman in top form: nearly bursting into a Navajo war chant, then pressing for an overhaul of the English language (if you want to know why Johnny can't read, just look at the spelling of "friend"); and, finally, ruminating on the death of his first wife from tuberculosis. This is quintessential Feynman -- reflective, amusing, and ever enlightening.
