pbAn introduction to modern physics and to Richard Feynman at his witty and enthusiastic best, discussing gravitation, irreversibility, symmetry, and the nature of scientific discovery.bppRichard 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. iThe Character of Physical Lawi, 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.ppIn 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 l
