When Darwin set out to explain the origin of species, he made no attempt to answer the deeper question- what is life?

For generations, scientists have struggled to make sense of this fundamental question. Life really does look like magic- even a humble bacterium accomplishes things so dazzling that no human engineer can match it. And yet, huge advances in molecular biology over the past few decades have served only to deepen the mystery. So can life be explained by known physics and chemistry, or do we need something fundamentally new?

In this penetrating and wide-ranging new analysis, world-renowned physicist and science communicator Paul Davies searches for answers in a field so new and fast-moving that it lacks a name, a domain where computing, chemistry, quantum physics and nanotechnology intersect. At the heart of these diverse fields, Davies explains, is the concept of information- a quantity with the power to unify biology with physics, transform technology and medicine, and even to illuminate the age-old question of whether we are alone in the universe.

From life's murky origins to the microscopic engines that run the cells of our bodies, The Demon in the Machine is a breath-taking journey across the landscape of physics, biology, logic and computing. Weaving together cancer and consciousness, two-headed worms and bird navigation, Davies reveals how biological organisms garner and process information to conjure order out of chaos, opening a window on the secret of life itself.

Paul Davies is a theoretical physicist, cosmologist, astrobiologist, author and broadcaster. On 1 September 2006 Paul Davies will take up a new position as college professor at Arizona State University, the largest public university campus in the USA. He will have the distinctive assignment to establish a new centre on foundational questions in science, to encompass cosmology, life, astrobiology and philosophy - a think tank for addressing complex issues in these areas.He has achieved an international reputation for his ability to explain the significance of advanced scientific ideas in simple language. He is the author of some twenty-five books including The Mind of God, The Last Three Minutes and How to Build a Time Machine. Among other awards he has won the Templeton Prize, The Royal Society's Michael Faraday Prize for science communication and a Glaxo Science Writers' Fellowship. In April 1999 the asteroid 1992 OG was officially named (6870) Pauldavies in his honour. Davies has extensive experience in all facets of the media. He writes regularly for newspapers, journals and magazines in several countries. Notable among his contributions to radio are a series of documentaries on BBC Radio 3, and his television work has ranged from chat shows to scripting and presenting various documentaries, including his own series entitled The Big Questions and More Big Questions. Committed to bringing science to the wider public, Davies engages in a heavy program of public lecturing around the world, addressing scientific and religious topics. As a supporter of the arts, he is also frequently involved in literary and artistic events both in Australia and internationally. The recipient of many awards and commendations, Davies won the Eureka Prize in 1991 for the promotion of science in Australia, and in 1993 he was presented with an Advance Australia Award for outstanding contributions to science. In 1995 Davies was awarded the Templeton Prize for progress in religion, the world's largest prize for intellectual endeavour. Paul Davies is married, and has four children. He remains a British citizen. In addition to his passion for both traditional and contemporary art, he is interested in the history of the second world war, politics and economics. He also enjoys keeping fit and discussing geographical trivia.

Reviews for The Demon in the Machine: How Hidden Webs of Information Are Finally Solving the Mystery of Life

What is life? Questions don't come much bigger than that. It's asked regularly by biologists, philosophers, lawyers, law-makers, astrobiologists and, occasionally, wide-eyed children. It's not so often asked by physicists, which makes Paul Davies' new book, The Demon In The Machine, that much more fascinating. * Sydney Morning Herald * Paul Davies takes us on a fascinating tour of what is known about what life is. Along the way he speculates interestingly about what may become known. His theme, drawn from Darwin, Schroedinger, Turing, Goedel, Shannon and von Neumann, is that what separates life from non-life is information. But how? Exploring that question illuminates biology by revealing its deep roots in physics, mathematics and computer science. -- David Deutsch A tour-de-force of a fascinating and frontier topic: information as a distinguishing, central aspect of those physical systems known as living ones. The Demon in the Machine is simultaneously rigorous, state-of-the-art, and highly readable - very hard to put down -- Michael Levin, Allen Discovery Center at Tufts University Paul Davies narrates a gripping new drama in science, in which the plot is the story of life and the leading actor is information. With his characteristic blend of erudition and clarity, he brings together some of the most rapidly advancing knowledge in physics and technology to show how information controls biology. If you want to understand how the concept of life is changing, read this. -- Professor Andrew Briggs, University of Oxford, author of The Penultimate Curiosity and It Keeps Me Seeking. The Demon in the Machine encompasses some of the most intriguing and unsolved mysteries of the universe: the existence of an arrow of time imprinted on the cosmos, and the emergence of life itself. Davies' crisp but rich narrative succeeds in untangling various highly complex ideas and processes, while fluently and intelligently setting out its own arrow of argument. -- Mikhail Prokopenko, The University of Sydney This creative demon shadows DNA and the promise of quantum computing, answering some basic questions. What is consciousness, why is life so good at predicting where it might go next? The bridge connecting fundamental physics, biology and the most advanced labs of computation is what Davies calls information patterns. He shows how it organizes for top-down creativity, and thereby holds off the grim reaper of entropy. With striking insight, and metaphors that illuminate the landscape of science today, Davies once again becomes a guide to the near future. -- Charles Jencks, The Garden of Cosmic Speculation Paul Davies always probes the deepest questions in science. Here, addressing the deepest of all -- Schroedinger's What is Life? -- he tells us what life is: matter plus information - beyond the laws of physics, but compatible with them. To elaborate this thesis, he deploys his trademark talent: getting to the heart of the most abstruse and technical aspects of science (biology as well as physics), without jargon and with down-to-earth analogies -- Michael Berry, HH Wills Physics Laboratory The molecular biology revolution has led to extraordinary understandings of how life emerges from physical processes. But comprehension of the nuts and bolts of these processes omits a key feature of what is going on: what separates life from non-life is information. In this characteristically clearly written and engaging book, ranging from physics to biology and evolutionary theory to neuroscience, Paul Davies strongly makes the case that at its core, life is about information flows. There is much food for thought here. Highly recommended. -- George F.R. Ellis, University of Cape Town, co-author of The Large Scale Structure of Space-Time This is one of the most exciting books I have read in years. Paul Davies celebrates a significant anniversary with a demonically brilliant investigation of a fundamental question that only the very latest science and philosophy can deal with. Now we have a view from the master that's as thrilling as it is satisfying. Superb. -- Robyn Williams Paul Davies is a courageous explorer of the boundaries of what we can know about our world. This book makes his explorations available to all who enjoy pushing those boundaries. Written with a light entertaining touch, even the most abstruse science acquires the clarity of exposition for which the author is justly renowned -- Denis Noble, University of Oxford, author of Dance to the Tune of Life: Biological Relativity Boundary-transcending ... Davies claims that life's defining characteristics are better understood in terms of information ... there is grandeur in this view of life * Nature * Important and imaginative -- Clive Cookson * Financial Times * Brilliantly vivid ... The big idea is that understanding the information flow in organisms might be the missing part of our scientific jigsaw puzzle. The informational approach [to life], in David's elegant and lucid exposition, is highly promising -- Steven Poole * Guardian *
