Ubiquity

“Buchanan succeeds where others fail. . . . [He] is able to communicate this novel way of thinking without compromising scientific integrity.”—New Scientist

“I grabbed this book and turned the pages. Does Buchanan get it right? Does he really understand how this might change the way we look at the world? He does. This is the book I wish I had written.”
—Per Bak, author of How Nature Works

“Ubiquity explains better than any previous book why many fields of the natural world and human life are unpredictable.”
—Financial Times (London)

“There are many subtleties and twists in the story to which we shall come later in this book, but the basic message, roughly speaking, is simple: The peculiar and exceptionally unstable organization of the critical state does indeed seem to be ubiquitous in our world. Researchers in the past few years have found its mathematical fingerprints in the workings of all the upheavals I’ve mentioned so far, as well as in the spreading of epidemics, the flaring of traffic jams, the patterns by which instructions trickle down from managers to workers in an office, and in many other things. At the heart of our story, then, lies the discovery that networks of things of all kinds—atoms, molecules, species, people, and even ideas—have a marked tendency to organize themselves along similar lines. On the basis of this insight, scientists are finally beginning to fathom what lies behind tumultuous events of all sorts, and to see patterns at work where they have never seen them before.”
