The idiosyncrasies of human decision-making have confounded economists and social theorists for years. If each person makes choices for personal (and often irrational) reasons, how can people's choices be predicted by a single theory? How can any economic, social, or political theory be valid? The truth is, none of them really are. Mark Buchanan makes the fascinating argument that the science of physics is beginning to provide a new picture of the human or "social atom," and help us understand the surprising, and often predictable, patterns that emerge when they get together. Look at patterns, not people, Buchanan argues, and rules emerge that can explain how movements form, how interest groups operate, and even why ethnic hatred persists. Using similar observations, social physicists can predict whether neighborhoods will integrate, whether stock markets will crash, and whether crime waves will continue or abate. Brimming with mind games and provocative experiments, The Social Atom is an incisive, accessible, and comprehensive argument for a whole new way to look at human social behavior.

But as Mark Buchanan brilliantly demonstrates with examples from the world all around us, there's a bigger force at work that explains the world far better. Surprisingly, th For readers of Freakonomics and The Wisdom of Crowds, an enlightening introduction to a groundbreaking physics-based view of the social world that reveals the essential simplicity of human behavior.
