"The Trouble with Physics" is a groundbreaking account of the state of modern physics: of how we got from Einstein and Relativity through quantum mechanics to the strange and bizarre predictions of string theory, full of unseen dimensions and multiple universes. Lee Smolin not only provides a brilliant layman's overview of current research as we attempt to build a 'theory of everything', but also questions many of the assumptions that lie behind string theory. In doing so, he describes some of the daring, outlandish ideas that will propel research in years to come.

Einsteins Unfinished Revolution

A daring new vision of quantum theory from one of the leading minds of contemporary physics Quantum physics is the golden child of modern science. It is the basis of our understanding of atoms, radiation, and so much else, from elementary particles and basic forces to the behavior of materials. But for a century it has also been the problem child of science: it has been plagued by intense disagreements between its inventors, strange paradoxes, and implications that seem like the stuff of fantasy. Whether it's Schrödinger's cat--a creature that is simultaneously dead and alive--or a belief that the world does not exist independently of our observations of it, quantum theory challenges our fundamental assumptions about reality. In Einstein's Unfinished Revolution, theoretical physicist Lee Smolin provocatively argues that the problems which have bedeviled quantum physics since its inception are unsolved and unsolvable, for the simple reason that the theory is incomplete. There is more to quantum physics, waiting to be discovered. Our task--if we are to have simple answers to our simple questions about the universe we live in--must be to go beyond quantum mechanics to a description of the world on an atomic scale that makes sense. In this vibrant and accessible book, Smolin takes us on a journey through the basics of quantum physics, introducing the stories of the experiments and figures that have transformed our understanding of the universe, before wrestling with the puzzles and conundrums that the quantum world presents. Along the way, he illuminates the existing theories that might solve these problems, guiding us towards a vision of the quantum that embraces common sense realism. If we are to have any hope of completing the revolution that Einstein began nearly a century ago, we must go beyond quantum mechanics to find a theory that will give us a complete description of nature. In Einstein's Unfinished Revolution, Lee Smolin brings us a step closer to resolving one of the greatest scientific controversies of our age.

Einstein's Unfinished Revolution: The Search for What Lies Beyond the Quantum

History & Philosophy

We live in the age of a new scientific revolution, one as sweeping and profound as that launched by Copernicus, one that continues to unfold. Beginning at the turn of the century, with the discovery of relativity and quantum mechanics, this second revolution has collapsed the elegant old Newtonian universe. Yet physicists have yet to complete a replacement, as they search for a grand unified theory. Now cosmologist Lee Smolin offers a startling new approach--a theory of the universe that is at once elegant, comprehensive, and radically different from anything proposed before. In The Life of the Cosmos, Smolin cuts the Gordian knot of cosmology with a simple, powerful idea: "The underlying structure of our world," he writes, "is to be found in the logic of evolution." Today's physicists, he writes, have overturned Newton's view of the universe, yet they continue to cling to an understanding of reality not unlike Newton's own--as a clock, an intricate yet static mechanism. Smolin sees the very fabric of reality as changing and developing. "The laws of nature themselves," he argues, "like the biological species, may not be eternal categories, but rather the creations of natural processes occurring in time." A process of self organization like that of biologal evolution shapes the universe, as it develops and eventually reproduces through black holes, each of which may result in a new big bang and a new universe. Natural selection may guide the appearance of the laws of physics, favoring those universes which best reproduce. Smolin's ideas are based on recent developments in cosmology, quantum theory, relativity and string theory, yet they offer, at the same time, a completely new view of how these developments may fit together to form a new theory of cosmology. The result will be a cosmology according to which the fact that the universe is a home to life will be seen to be a natural consequence of the fundamental principles on which it has been built. This will be in direct contrast with the older point of view, coming from Newtonian physics, according to which the fact that the universe contains life, or any form of organization, is accidental. We exist in a universe filled with an array of beautiful structures ranging from the molecular organization of living things upwards to the galaxies, and science must ultimately explain why. In so doing, science will give us a picture of the universe in which, as the author writes, "the occurrence of novelty, indeed the perpetual birth of novelty, can be understood." Lee Smolin is one of the leading cosmologists at work today, and he writes with an expertise and force of argument that will command attention throughout the world of physics. As startling as many of his ideas sound, each is subject to testing, and he includes several ideas on how they might be confirmed or disproved. Perhaps most important, however, is the humanity and sharp clarity of his prose, offering access for the layperson to the mind bending space at the forefront of today's physics.

Cosmologist Lee Smolin offers a startling new theory of the universe that is at once elegant, comprehensive, and radically different from anything proposed before. In The Life of the Cosmos, Smolin cuts the Gordian knot of cosmology with a simple, powerful idea: "The underlying structure of our world, " he writes, "is to be found in the logic of evolution." Today's physicists have overturned Newton's view of the universe, yet they continue to cling to an understanding of reality not unlike Newton's own - as a clock, an intricate mechanism, governed by laws which are mathematical and eternally true. Smolin argues that the laws of nature we observe may be in part the result of a process of natural selection which took place before the big bang. Smolin's ideas are based on recent developments in cosmology, quantum theory, relativity and string theory, yet they offer, at the same time, an unprecedented view of how these developments may fit together to form a new theory of cosmology. From this perspective, the lines between the simple and the complex, the fundamental and the emergent, and even between the biological and the physical are redrawn. The result is a framework that illuminates many intractable problems, from the paradoxes of quantum theory and the nature of space and time to the problem of constructing a final theory of physics. As he argues for this new view, Smolin introduces the reader to recent developments in a wide range of fields, from string theory and quantum gravity to evolutionary theory the structure of galaxies. He examines the philosophical roots of controversies in the foundations of physics, and shows how they may be transformed as science moves towardunderstanding the universe as an interrelated, self-constructed entity, within which life and complexity have a natural place, and in which "the occurrence of novelty, indeed the perpetual birth of novelty, can be understood."

Since the ancients, physicists have argued that time is not real, that we may think we experience time passing but it's just a human illusion in a timeless universe operating on predetermined laws. Lee brilliantly shows how this thinking came about from our deep need for stability and the eternal, but that indeed time may be the only thing that is real.
