'Six degrees of separation' is a cliche, as is 'it's a small world', both cliches of the language and cliches of everyone's experience. We all live in tightly bonded social networks, yet linked to vast numbers of other people more closely than we sometimes think. Only in recent years, however, have scientists begun to apply insights from the theoretical study of networks to understand forms of network as superficially different as social networks and electrical networks, computer networks and economic networks, and to show how common principles underlie them all. Duncan Watts explores the science of networks and its implications, ranging from the Dutch tulipmania of the 17th century to the success of Harry Potter, from the impact of September 11 on Manhattan to the brain of the sea- slug, from the processes that lead to stockmarket crashes to the structure of the world wide web. As stimulating and life- changing as James Gleick's CHOAS, SIX DEGREES is a ground- breaking and important book.
"The insights here are fairly mind-blowing" Independent "Accessible and engaging" Nature "A fascinating read" Good Book Guide "Watts looks at the new science of connectivity studies in a new and informative way...he takes us on a fascinating tour of a newly emerging subject" Focus "Watt's theory is exciting for various reasons, but particularly because it brings together ideas from mathematics, physics and the social science. Oh, and popular culture, of course" Independent on Sunday
