So, why do we perceive a flow of time? Is the future “already there”, and is the past “still there”, even though we are only aware of a single moment of time? Drawing on the latest ideas from both relativity and quantum theory, award-winning science writer John Gribbin (In Search of Schrödinger’s Cat) addresses the questions that have baffled philosophers since antiquity and Zeno’s arrow paradox. Along the way, we find that in the quantum world it is literally true that a watched pot never boils, and learn how physicists have come to terms with the idea of the four-dimensional block universe as an explanation of the distinction between past, present and future. Why do eggs break when we drop them, but never unbreak? The Universe as we know it began in a Big Bang, which in some sense marks the beginning of time. Is it possible that we need to invoke the Big Bang to explain why we never see unbroken eggs? This idea glories in the name “the past hypothesis”, but many physicists regard it as no more than an attempt to sweep the problem of the arrow of time under the rug.

    His influence on 20th-century thinking and issues is arguably unparalleled, affecting attitudes on sex, religion, art, culture, and more. Written for the layperson, Freud for Beginners explains the doctor's dogma with wit and clarity, all in a contemporary context.

    Now he stands ready to revolutionize both neuroscience and computing in one stroke, with a new understanding of intelligence itself.Hawkins develops a powerful theory of how the human brain works, explaining why computers are not intelligent and how, based on this new theory, we can finally build intelligent machines.The brain is not a computer, but a memory system that stores experiences in a way that reflects the true structure of the world, remembering sequences of events and their nested relationships and making predictions based on those memories. It is this memory-prediction system that forms the basis of intelligence, perception, creativity, and even consciousness.In an engaging style that will captivate audiences from the merely curious to the professional scientist, Hawkins shows how a clear understanding of how the brain works will make it possible for us to build intelligent machines, in silicon, that will exceed our human ability in surprising ways.Written with acclaimed science writer Sandra Blakeslee, On Intelligence promises to completely transfigure the possibilities of the technology age. It is a landmark book in its scope and clarity.

    And two giants at the foundations of modern science were converging, step-by-step, on the answer: Albert Einstein, an young, obscure German physicist experimenting with measuring time using telegraph networks and with the coordination of clocks at train stations; and the renowned mathematician Henri Poincaré, president of the French Bureau of Longitude, mapping time coordinates across continents. Each found that to understand the newly global world, he had to determine whether there existed a pure time in which simultaneity was absolute or whether time was relative.Esteemed historian of science Peter Galison has culled new information from rarely seen photographs, forgotten patents, and unexplored archives to tell the fascinating story of two scientists whose concrete, professional preoccupations engaged them in a silent race toward a theory that would conquer the empire of time.

    It comprises non-technical essays on every aspect of the vast subject, including articles by scores of eminent mathematicians and other thinkers.

    It draws on the increasing evidence accumulated over recent decades that prehistoric humanity was peaceful and egalitarian, rather than war-like and crude. It is not natural for human beings to kill each other, for men to oppress women, for individuals to accumulate massive wealth and power, or to abuse nature. The worldwide myths of a Golden Age or an original paradise have a factual, archaeological basis.

    But was he right? Can the quantum theory of fields and Einstein's general theory of relativity, the two most accurate and successful theories in all of physics, be united in a single quantum theory of gravity? Can quantum and cosmos ever be combined? On this issue, two of the world's most famous physicists--Stephen Hawking ("A Brief History of Time") and Roger Penrose ("The Emperor's New Mind" and "Shadows of the Mind")--disagree. Here they explain their positions in a work based on six lectures with a final debate, all originally presented at the Isaac Newton Institute for Mathematical Sciences at the University of Cambridge.How could quantum gravity, a theory that could explain the earlier moments of the big bang and the physics of the enigmatic objects known as black holes, be constructed? Why does our patch of the universe look just as Einstein predicted, with no hint of quantum effects in sight? What strange quantum processes can cause black holes to evaporate, and what happens to all the information that they swallow? Why does time go forward, not backward?In this book, the two opponents touch on all these questions. Penrose, like Einstein, refuses to believe that quantum mechanics is a final theory. Hawking thinks otherwise, and argues that general relativity simply cannot account for how the universe began. Only a quantum theory of gravity, coupled with the no-boundary hypothesis, can ever hope to explain adequately what little we can observe about our universe. Penrose, playing the realist to Hawking's positivist, thinks that the universe is unbounded and will expand forever. The universe can be understood, he argues, in terms of the geometry of light cones, the compression and distortion of spacetime, and by the use of twistor theory. With the final debate, the reader will come to realize how much Hawking and Penrose diverge in their opinions of the ultimate quest to combine quantum mechanics and relativity, and how differently they have tried to comprehend the incomprehensible.

    The chapters may be read independently of one another. But when read in order, they tell a more or less continuous story. We begin with some reflections about the legacy of Socrates and then go on to the existence of God, which is perhaps the most basic philosophical question of all because our answer to it influences how we will answer all the others. This leads naturally to a discussion of death and the soul, and then to more modern ideas about the nature of persons. The later chapters are about whether it is possible for us to have objective knowledge in either science or ethics. James Rachels, from the Preface Problems from Philosophy and The Truth About the World: Basic Readings in Philosophy are at once James Rachels' newest contributions to philosophy and his last. In these two books, Rachels found a culminating expression for his love of philosophy.

    As he wanders the land year upon year, Raymo gathers the revelations embedded in the geological and cultural history of this wild and ancient place.

    Donning cape and mask as “The Underground Grammarian,” Mitchell sallied forth upon his newsletter against the nonsense being spoken, written, and, indeed, encouraged by the educational establishment. (“One thing led to another,” as he tells it, “a front page piece in The Wall Street Journal, a proÞle in Time, and other such. Before it was over, The Underground Grammarian came to be, in the world of desktop printing, the Þrst publication to have subscribers on every continent except Antarctica.”) What began as a vivid catalog of ignorance and inanity in the written work of professional educators and their hapless students soon became an enterprise of most noble moment: an investigation, via mordant wit and Þerce intelligence, of “what we might usefully decide to mean by ‘education.’” The results of Mitchell’s inquiries are as stimulating today as they were when Þrst articulated. His project remains a telling explication of how, through writing, we discover thought and make knowledge. It is certainly the most drolly entertaining.
