A Beautiful Math: John Nash, Game Theory, and the Modern Quest for a Code of Nature

The title capitalizes on the popularity of the Oscar-winning movie about Nobel Prize–winning mathematician John Nash. But this is a serious and adroit look at a branch of mathematics, influenced by Nash's work, that is steadily sending tendrils into nearly every area of science. It may even, says science journalist Siegfried, result in a mathematical description of nature of the sort imagined and called "psychohistory" by Isaac Asimov in his Foundation trilogy. Siegfried is talking about game theory, which was originally conceived as a model of economics predicting what rational people would do when competing for monetary gain. But with the help of the "Nash equilibrium," it has since evolved into a system that helps describe social networking, physics, evolution and more. In guiding the reader through the outgrowths of game theory, Siegfried steps nimbly around anything that would bog down the narrative, crisply painting the key concepts and framing them with pop culture, biographies of and conversations with giants in the field, and reacting ("Now, you have to admit, that's a little strange") to each new discovery. His clear and easy voice makes the content effortless and a pleasure to read. (Oct. 20)
