Steven Johnson's "Emergence: The Connected Lives of Ants, Brains, Cities and Software" is a fascinating look at how self-organising systems are changing the world. Why do people cluster together in neighborhoods? How do internet communities spring up from nowhere? Why is a brain conscious even though no single neuron is? What causes a media frenzy? The answer, as Steven Johnson's groundbreaking book shows, is emergence: change that occurs from the bottom up. When enough individual elements interact and organize themselves, the result is collective intelligence - even though no-one is in charge. It is a phenomenon that exists at every level of experience, and will revolutionize the way we see the world. "Exhilarating". (J.G. Ballard). "A dizzying, dazzling romp through fields as disparate as urban planning, computer-game design, neurology and control theory". ("Economist"). "Mind-expanding ...intelligent, witty and tremendously thought-provoking...Popular science books interesting enough to read twice don't come along all that often". ("Guardian"). "Not just a fascinating quirk of science: it's the future". ("The New York Times").
