Richard Feynman, Nobel Prize winner for his work on the description and calculation of interactions between particles, was a genius of our time. Quantum physics theoretician, enfant terrible of the Manhattan project and ascerbic critic of the investigative committee of the American space shuttle, Feynman left a profound impression on modern physics. James Gleick, a former journalist at The New York Times and author of the best-selling Chaos Theory, tells how Feynman's ideas were formed and how he reinvented particle physics. Through this portrait, Gleick explores the nature of genius itself and provides insight about the fascination that it engenders.
