How Hidden Webs of Information Are Finally Solving the Mystery of Life

The Demon in the Machine

'A gripping new drama in science ... if you want to understand how the concept of life is changing, read this' Professor Andrew Briggs, University of Oxford 
 
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.

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

Boundary-transcending ... Davies claims that life's defining characteristics are better understood in terms of information ... there is grandeur in this view of life

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

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.

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

Paul Davies always probes the deepest questions in science. Here, addressing the deepest of all -- Schrödinger'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

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

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

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.

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 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, Schrödinger, Turing, Gödel, 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.

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.

Are We Alone in the Universe?

The Eerie Silence

Searching for Ourselves in the Universe

Paul Davies' The Eerie Silence: Searching For Ourselves in the Universe is an engaging and lucid guide to the 'Fermi Paradox' - why isn't the universe teeming with alien life? 
 
 If aliens ever contact us, it will be the single most significant event in human history. And Paul Davies will be responsible for saying something back. 
 
 For fifty years the Search for Extra-Terrestrial Intelligence has been scanning the skies. Now Davies, head of SETI's Post-Detection Task Group, with 'a rare talent for making physics mind-bogglingly vivid and exciting' (Times Higher Education), explores what the mysterious silence it has encountered could mean. 
 
 Here he looks at exciting new ways to make contact with extra-terrestrial life. He considers what form advanced alien intelligence is likely to take if it exists. And more importantly, what exactly it would mean if it didn't ­- how extraordinary it would be if we were alone, to be human and here in this staggering, eerie silence...

Why is the Universe Just Right for Life?

The Goldilocks Enigma

From the bestselling author of The Mind of God

Paul Davies' The Goldilocks Enigma: Why is the Universe Just Right for Life? gets to the heart of what makes the universe tick ­- and what makes our place in it so special. 
 
 It's not too hot, it's not too cold, and its forces act together in a way that's just right: why does the universe seem so perfectly tailor-made for life to exist? 
 
 Paul Davies, one of the world's most acclaimed science writers, shows how everything from the humble carbon atom to the speed of light and the laws of physics themselves interact. He asks: is there a theory of everything within our grasp? If there was a big bang, what happened before it? Is there on universe or many? Could we exist within an endless time loop?

The Goldilocks Enigma is Paul Davies spectacular and eagerly awaited return to cosmology. Here he tackles all the 'big questions' and introduces the latest discoveries that have allowed scientists to piece together the story of the universe in unprecedented detail. And he explains why, despite all this, cosmologists are more divided than ever. Why is everything just right for life on earth? And how have we tried to explain this? How has belief shaped the scientific debate? What do we really know about our place in the universe? Paul Davies decodes the real science and gets to the very heart of our understanding of the universe.

God and the New Physics

In God and the New Physics, Paul Davies explains how science has come of age, and can now offer a surer path to divinity than religion. 
 
Science is now on the verge of answering our most profound questions about the nature of existence. Here Paul Davies explains how the far-reaching discoveries of recent physics are revolutionizing our world and, in particular, throwing light on many of the questions formerly posed by religion, such as: 
 
Why is there a universe? 
Where did we come from? 
What is life? 
How is the world organized? 
 
Examining subjects from the creation to the soul, free will to time, black holes to miracles, he travels through science and religion to show us that there is more to the world than meets the eye.

Science and the Search for Ultimate Meaning

The Mind of God

Paul Davies' The Mind of God: Science and the Search for Ultimate Meaning explores how modern science is beginning to shed light on the mysteries of our existence. 
 
 Is the universe - and our place in it - the result of random chance, or is there an ultimate meaning to existence? Where did the laws of nature come from? Were they created by a higher force, or can they be explained in some other way? How, for example, could a mechanism as complex as an eye have evolved without a creator? 
 
 Paul Davies argues that the achievement of science and mathematics in unlocking the secrets of nature mean that there must be a deep and significant link between the human mind and the organization of the physical world. In this quest for an ultimate explanation of the universe, he examines the origin of the cosmos, the possibility of other universes and the claim that we inhabit a kind of gigantic computer. The universe is, he concludes, no mere quirk of fate but a meaningful place for thinking beings. Through science, we can truly glimpse the mind of God.

Einstein's Unfinished Revolution

About Time

In About Time: Einstein's Unfinished Revolution Paul Davies confronts the puzzles and paradoxes of time that have bemused the world's greatest thinkers throughout the ages. 
 
When Albert Einstein formulated his theory of relativity it brought about a revolution in our understanding of time, yet also presented a new set of mysteries. Einstein's time can be warped, leading to bizarre possibilities such as black holes and time travel, while making a nonsense of our perception of a 'now' or a division of time into past, present and future. 
 
In About Time Paul Davies tackles the tough questions about time, including the strange relationship between physical time and our psychological perception of it. He gives straightforward descriptions of topics such as the theory of relativity, the relation between time dilation and the speed of light and Hawking's 'imaginary time'. He concludes that, despite decades of progress in unravelling the mysteries of time, the revolution is still underway...

And Other Cosmic Questions

In the constellation of Eridanus there lurks a cosmic mystery. It's as if something has taken a huge bite out of the universe, leaving a super-void. What could be the culprit? A super massive black hole? Another, bigger universe? Or an expanding vacuum bubble, destined to envelop and annihilate everything in existence? 
 
Scientists now understand the history of our universe better than the history of our own planet, but they continue to uncover startling new riddles-the hole in the universe being just one. In this electrifying book, award-winning physicist Paul Davies walks us through the puzzles and paradoxes that have preoccupied cosmologists from ancient Greece to the present day. Laying bare the audacious research that has led us to mind-bending solutions, Davies reveals how we might begin to approach the greatest outstanding enigmas of all.
