An electrifying biography of one of the most extraordinary scientists of the twentieth century and the world he made. The smartphones in our pockets and computers like brains. The vagaries of game theory and evolutionary biology. Nuclear weapons and self-replicating spacecraft's. All bear the fingerprints of one remarkable, yet largely overlooked, man- John von Neumann. Born in Budapest at the turn of the century, von Neumann is one of the most influential scientists to have ever lived. A child prodigy, he mastered calculus by the age of eight, and in high school made lasting contributions to mathematics. In Germany, where he helped lay the foundations of quantum mechanics, and later at Princeton, von Neumann's colleagues believed he had the fastest brain on the planet-bar none. He was instrumental in the Manhattan Project and the design of the atom bomb, he helped formulate the bedrock of Cold War geopolitics and modern economic theory, he created the first ever programmable digital computer, he prophesized the potential of nanotechnology, and, from his deathbed, he expounded on the limits of brains and computers-and how they might be overcome.
