Perhaps the greatest physicist of the second half of the twentieth century, Richard Feynman changed the way we think about quantum mechanics, the most perplexing of all physical theories. Here Krauss, himself a theoretical physicist and bestselling author, offers a unique scientific biography: a rollicking narrative coupled with clear and novel expositions of science at the limits. An immensely colorful person, Feynman revolutionized our understanding of nature amid a turbulent life. From the death of Feynman's childhood sweetheart during the Manhattan Project to his reluctant rise as a scientific icon, Krauss presents that life as seen through the science. An accessible reflection on the issues that drive physics today, Quantum Man captures the story of a man who was willing to break all the rules to tame a theory that broke all the rules.
