“A splendid, edifying report from the front lines of theorectical physics” (San Francisco Chronicle). In this illuminating book, renowned physicist Lee Smolin argues that fundamental physics—the search for the laws of nature—is losing its way. Ambitious ideas about extra dimensions, exotic particles, multiple universes, and strings have captured the public’s imagination—and the imagination of experts. But these ideas have not been tested experimentally, and some, like string theory, seem to offer no possibility of being tested. Even still, these speculations dominate the field, attracting the best talent and much of the funding, while creating a climate in which emerging physicists are often penalized for pursuing other avenues. The situation threatens to impede the very progress of science. With clarity, passion, and authority, Smolin offers an unblinking assessment of the troubles that face modern physics, and an encouraging view of where the search for the next big idea may lead. “The best book about contemporary science written for the layman that I have ever read.” —The Times (London)

Human beings, says Lee Smolin, author of The Trouble With Physics, have always had a problem with the boundary between reality and fantasy, confusing our representations of the world with the world itself. Nowhere is this more evident than in quantum physics, which forms the basis for our understanding of everything from elementary particles to the behaviour of materials. While quantum mechanics is currently our best theory of nature at an atomic scale, it has many puzzling qualities - qualities that preclude realism and therefore give an incomplete description of nature. Rather than question this version of quantum mechanics, however, whole groups of physicists have embraced it as correct and rejected realism. Subscribing to a kind of magical thinking, they believe that what is real is far beyond the world we perceive: indeed, that the 'true' world is hidden from our perception. Back in the 1920s Einstein, both a realist and a physicist, believed that it was necessary to go beyond quantum mechanics to discover what was missing from a true theory of the atoms. This was Einstein's unfinished mission, and it is Lee Smolin's too. Not only will this new model of quantum physics form the basis of solutions to many of the outstanding problems of physics, but, crucially, it is a theory that is realist in nature. At a time when science is under attack, and with it the belief in a real world in which facts are either true or false, never has the importance of building science on the correct foundations been more urgent.

A radical new view of the nature of time and the cosmos—“at once entertaining, thought-provoking, fabulously ambitious and fabulously speculative” (The New York Times Book Review). What is time? This deceptively simple question is the single most important problem facing science as we probe deeper into the fundamentals of the universe. All of the mysteries physicists and cosmologists face—from the Big Bang to the future of the universe, from the puzzles of quantum physics to the unification of forces and particles—come down to the nature of time. The fact that time is real may seem obvious. You experience it passing every day when you watch clocks tick, bread toast, and children grow. But most physicists, from Newton to Einstein to today’s quantum theorists, have seen things differently. The scientific case for time being an illusion is formidable. That is why the consequences of adopting the view that time is real are revolutionary. Here, the author of The Trouble with Physics argues that a limited notion of time is holding physics back—and what we need now is a major shift in scientific thought. The true reality of this manmade construct could be the key to the next big breakthrough in theoretical physics—and could hold implications relevant to issues from climate change to the economy. What if the laws of physics themselves were not ageless? What if they could evolve? Time Reborn offers a radical approach to cosmology that embraces the concept of time and opens up a whole new universe of possibilities. “With rare conceptual daring, Smolin beckons toward a new perspective for doing cosmological theory . . . A thrilling intellectual ride.” —Booklist, starred review

Today we are blessed with two extraordinarily successful theories of physics. The first is Albert Einstein's general theory of relativity, which describes the large-scale behaviour of matter in a curved spacetime. This theory is the basis for the standard model of big bang cosmology. The discovery of gravitational waves at the LIGO observatory in the US (and then Virgo, in Italy) is only the most recent of this theory's many triumphs. The second is quantum mechanics. This theory describes the properties and behaviour of matter and radiation at their smallest scales. It is the basis for the standard model of particle physics, which builds up all the visible constituents of the universe out of collections of quarks, electrons and force-carrying particles such as photons. The discovery of the Higgs boson at CERN in Geneva is only the most recent of this theory's many triumphs. But, while they are both highly successful, these two structures leave a lot of important questions unanswered. They are also based on two different interpretations of space and time, and are therefore fundamentally incompatible. We have two descriptions but, as far as we know, we've only ever had one universe. What we need is a quantum theory of gravity. Approaches to formulating such a theory have primarily followed two paths. One leads to String Theory, which has for long been fashionable, and about which much has been written. But String Theory has become mired in problems. In this book, Jim Baggott describes ": an approach which takes relativity as its starting point, and leads to a structure called Loop Quantum Gravity. Baggott tells the story through the careers and pioneering work of two of the theory's most prominent contributors, Lee Smolin and Carlo Rovelli. Combining clear discussions of both quantum theory and general relativity, this book offers one of the first efforts to explain the new quantum theory of space and time.

"Following Vattimo's postmodern philosophy, Badiou's postmetaphysical ontology, and i ek's revolutionary style, the authors of this marvelous book invites us to reactivate our politics of resistance against our greatest enemy: corporate capitalism. The best solution to the ecological, energy, and financial crisis corporate capitalism has created, as Crockett Clayton and Jeffrey Robbins suggest, is a new theological materialism where Being is conceived as energy both subjectively and objectively. All my graduate students will have to read this book carefully if they want to become philosophers." - Santiago Zabala, ICREA Research Professor at the University of Barcelona "This is a book of an extraordinary timeliness, written in an accessible and strikingly informative way. It is excellently poised to become a synthetic and agenda setting statement about the implications of a new materialism for the founding of a new radical theology, a new kind of spirituality. I consider this therefore quite a remarkable book which will be influential in ongoing discussions of psychoanalysis, continental philosophy, and theology. Moreover, it will be, quite simply, the best book about spirituality and the new materialism on the market today. While all of the work of the new materialists engage at one level or another the question of a new spirituality, I do not think there is anything comparable in significance to what Crockett and Robbins have provided here." - Ward Blanton, University of Kent "This book will perhaps be most appreciated by the reader with an intuitive cast of mind, able to recognize the force of an argument in its imaginative suggestiveness . . . New Materialism is about energy transformation, we are told, energy which cannot be reduced to matter because it resonates with spirit and life . . . Yet the book strikes a fundamental note of hard reality: 'if we want our civilization to live on earth a little longer we will have to recognize our coexistence with and in earth'." - Christian Ecology Link

Utterly beautiful. Profoundly disconcerting. Quantum theory is quite simply the most successful account of the physical universe ever devised. Its concepts underpin much of the twenty-first century technology that we now take for granted. But at the same time it has completely undermined our ability to make sense of the world at its most fundamental level. Niels Bohr claimed that anybody who is not shocked by the theory has not understood it. The American physicist Richard Feynman went further: he claimed that nobody understands it. The Quantum Story begins in 1900, tracing a century of game-changing science. Popular science writer Jim Baggott first shows how, over the space of three decades, Einstein, Bohr, Heisenberg, and others formulated and refined the theory--and opened the floodgates. Indeed, since then, a torrent of ideas has flowed from the world's leading physicists, as they explore and apply the theory's bizarre implications. To take us from the story's beginning to the present day, Baggott organizes his narrative around forty turning-point moments of discovery. Many of these are inextricably bound up with the characters involved--their rivalries and their collaborations, their arguments and, not least, their excitement as they sense that they are redefining what reality means. Through the mix of story and science, we experience their breathtaking leaps of theory and experiment, as they uncover such undreamed of and mind-boggling phenomenon as black holes, multiple universes, quantum entanglement, the Higgs boson, and much more. Brisk, clear, and compelling, The Quantum Story is science writing at its best. A compelling look at the one-hundred-year history of quantum theory, it illuminates the idea as it reveals how generations of physicists have grappled with this monster ever since.
