As Chaos explained the science of disorder, Nexus: Small Worlds and the Groundbreaking Science of Networks reveals the new science of connection and the odd logic of six degrees of separation.

How can geometry explain the puzzles of human behavior? In this incisive, insightful work Mark Buchanan presents the fundamental principles of the emerging field of “small worlds” theory—the idea that a hidden pattern is the key to how networks interact and exchange information, whether that network is the information highway or the firing of neurons in the brain.

Nexus is an exciting introduction to the hidden geometry that weaves our lives so inextricably together.
