The demon in the machine how hidden webs of information are solwing the mytstery of life

"How does life create order from chaos? And just what is life, anyway? Leading physicist Paul Davies argues that to find the answers, we must first answer a deeper question: 'What is information?' To understand the origins and nature of life, Davies proposes a radical vision of biology which sees the underpinnings of life as similar to circuits and electronics, arguing that life as we know it should really be considered a phenomenon of information storage. In an extraordinary deep dive into the real mechanics of what we take for granted, Davies reveals how biological processes, from photosynthesis to birds' navigation abilities, rely on quantum mechanics, and explores whether quantum physics could prove to be the secret key of all life on Earth. Lively and accessible, Demons in the Machine boils down intricate interdisciplinary developments to take readers on an eye-opening journey towards the ultimate goal of science: unifying all theories of the living and the non-living, so that humanity can at last understand its place in the universe."-- Publisher description '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.
