Many of Ian Fleming's short stories have been the inspiration for the extremely successful James Bond film franchise, and included in this collection are such stories as Octopussy, The Living Daylights, and For Your Eyes Only. The title story, Quantum of Solace, lends its name to the upcoming James Bond film, slated to release in Fall 2008. This collection will be published to coincide with the film's release, as well as to continue Penguin's centenary celebrations of Fleming's birth.
In a detailed reconstruction of the genesis of Feynman diagrams the author reveals that their development was constantly driven by the attempt to resolve fundamental problems concerning the uninterpretable infinities that arose in quantum as well as classical theories of electrodynamic phenomena. Accordingly, as a comparison with the graphical representations that were in use before Feynman diagrams shows, the resulting theory of quantum electrodynamics, featuring Feynman diagrams, differed significantly from earlier versions of the theory in the way in which the relevant phenomena were conceptualized and modelled.

Quantum: Einstein, Bohr and the Great Debate
Quantum theory is weird. As Niels Bohr said, if you aren't shocked by quantum theory, you don't really understand it. For most people, quantum theory is synonymous with mysterious, impenetrable science. And in fact for many years it was equally baffling for scientists themselves. In this tour de force of science history, Manjit Kumar gives a dramatic and superbly written account of this fundamental scientific revolution, focusing on the central conflict between Einstein and Bohr over the nature of reality and the soul of science.
