Although the laws of physics create a powerful impression that time is flowing, in fact there are only timeless `nows'. In The End of Time, the British theoretical physicist Julian Barbour describes the coming revolution in our understanding of the world: a quantum theory of the universe that brings together Einstein's general theory of relativity - which denies the existence of a unique time - and quantum mechanics - which demands one. Barbour believes that only the most radical of ideas can resolve the conflict between these two theories: that there is, quite literally, no time at all. The End of Time is the first full-length account of the crisis in our understanding that has enveloped quantum cosmology. Unifying thinking that has never been brought together before in a book for the general reader, Barbour reveals the true architecture of the universe and demonstrates how physics is coming up sharp against the extraordinary possibility that the sense of time passing emerges from a universe that is timeless. The heart of the book is the author's lucid description of how a world of stillness can appear to be teeming with motion: in this timeless world where all possible instants coexist, complex mathematical rules of quantum mechanics bind together a special selection of these instants in a coherent order that consciousness perceives as the flow of time. Finally, in a lucid and eloquent epilogue, the author speculates on the philosophical implications of his theory: Does free will exist? Is time travel possible? How did the universe begin? Where is heaven? Does the denial of time make life meaningless? Written with exceptional clarity and elegance, this profound and original work presents a dazzlingly powerful argument that all will be able to follow, but no-one with an interest in the workings of the universe will be able to ignore.

    Yet it is so ravaged by human activity that half its species could be gone by the end of the present century. These two contrasting truths—unexpected magnificence and underestimated peril—have become compellingly clear during the past two decades of research on biological diversity.In this dazzlingly intelligent and ultimately hopeful book, Wilson describes what treasures of the natural world we are about to lose forever—in many cases animals, insects, and plants we have only just discovered, and whose potential to nourish us, protect us, and cure our illnesses is immeasurable—and what we can do to save them. In the process, he explores the ethical and religious bases of the conservation movement and deflates the myth that environmental policy is antithetical to economic growth by illustrating how new methods of conservation can ensure long-term economic well-being.The Future of Life is a magisterial accomplishment: both a moving description of our biosphere and a guidebook for the protection of all its species, including humankind.

    The planet most like ours, it has still been thought impossible to reach, let alone explore and inhabit.Now with the advent of a revolutionary new plan, all this has changed. leading space exploration authority Robert Zubrin has crafted a daring new blueprint, Mars Direct, presented here with illustrations, photographs, and engaging anecdotes.The Case for Mars is not a vision for the far future or one that will cost us impossible billions. It explains step-by-step how we can use present-day technology to send humans to Mars within ten years; actually produce fuel and oxygen on the planet's surface with Martian natural resources; how we can build bases and settlements; and how we can one day "terraform" Mars--a process that can alter the atmosphere of planets and pave the way for sustainable life.

    At age thirteen, he is mentally and developmentally between one and three years old and will need constant care for the rest of his life. Brown travels the globe, meeting with genetic scientists and neurologists as well as parents, to solve the questions Walker’s doctors can’t answer. In his journey, he offers an insightful critique of society’s assumptions about the disabled, and he discovers a connected community of families living with this illness. As Brown gradually lets go of his self-blame and hope for a cure, he learns to accept the Walker he loves, just as he is. Honest, intelligent, and deeply moving, The Boy in the Moon explores the value of a single human life.

    Everything around us, including matter, is energy. A deep look into the mysteries of the subatomic world – the particles that make up the atom – provides answers to basic questions about how the universe works. To solve the future of mankind’s energy needs we need to understand the basic building blocks of the universe, including the atom and its parts. By exploring the subatomic world we’ll find more answers to our questions about time, forces like gravity and the matter that surrounds us. More importantly, we’ll find new ways to tap into the energy that exists around us to power our growing needs. In a new branch of particle physics, where tiny particles are thought of as energy waves, we find new answers that may help us in our quest to find alternative energy sources.

    Eventually he left his life in science to study with Tibetan teachers, and he is now a Buddhist monk and translator for the Dalai Lama, living in the Shechen monastery near Kathmandu in Nepal. Trinh Thuan was born into a Buddhist family in Vietnam but became intrigued by the explosion of discoveries in astronomy during the 1960s. He made his way to the prestigious California Institute of Technology to study with some of the biggest names in the field and is now an acclaimed astrophysicist and specialist on how the galaxies formed. When Matthieu Ricard and Trinh Thuan met at an academic conference in the summer of 1997, they began discussing the many remarkable connections between the teachings of Buddhism and the findings of recent science. That conversation grew into an astonishing correspondence exploring a series of fascinating questions. Did the universe have a beginning? Or is our universe one in a series of infinite universes with no end and no beginning? Is the concept of a beginning of time fundamentally flawed? Might our perception of time in fact be an illusion, a phenomenon created in our brains that has no ultimate reality? Is the stunning fine-tuning of the universe, which has produced just the right conditions for life to evolve, a sign that a “principle of creation” is at work in our world? If such a principle of creation undergirds the workings of the universe, what does that tell us about whether or not there is a divine Creator? How does the radical interpretation of reality offered by quantum physics conform to and yet differ from the Buddhist conception of reality? What is consciousness and how did it evolve? Can consciousness exist apart from a brain generating it?The stimulating journey of discovery the authors traveled in their discussions is re-created beautifully in The Quantum and the Lotus, written in the style of a lively dialogue between friends. Both the fundamental teachings of Buddhism and the discoveries of contemporary science are introduced with great clarity, and the reader will be profoundly impressed by the many correspondences between the two streams of thought and revelation. Through the course of their dialogue, the authors reach a remarkable meeting of minds, ultimately offering a vital new understanding of the many ways in which science and Buddhism confirm and complement each other and of the ways in which, as Matthieu Ricard writes, “knowledge of our spirits and knowledge of the world are mutually enlightening and empowering.” “The Quantum and the Lotus is a mind-expanding, eye-opening exploration of the exciting parallels between cutting-edge thinking in physics and Buddhism–a scintillating conversation any thinking person would delight in overhearing.” —Daniel Goleman, author of Emotional Intelligence“The Quantum and the Lotus is the rich and inspiring result of a deeply interesting dialogue between Western science and Buddhist philosophy. This remarkable book will contribute greatly to a better understanding of the true nature of our world and the way we live our lives.” —His Holiness the Dalai Lama

     The Science Book covers every area of science--astronomy, biology, chemistry, geology, math, and physics, and brings the greatest scientific ideas to life with fascinating text, quirky graphics, and pithy quotes.

    But almost everything about it, from the elements that forged stars, planets, and lifeforms, to the fundamental forces of physics, can be traced back to what happened in just the first three minutes of its life.In this book, Nobel Laureate Steven Weinberg describes in wonderful detail what happened in these first three minutes. It is an exhilarating journey that begins with the Planck Epoch - the earliest period of time in the history of the universe - and goes through Einstein's Theory of Relativity, the Hubble Red Shift, and the detection of the Cosmic Microwave Background. These incredible discoveries all form the foundation for what we now understand as the "standard model" of the origin of the universe. The First Three Minutes examines not only what this model looks like, but also tells the exciting story of the bold thinkers who put it together.Clearly and accessibly written, The First Three Minutes is a modern-day classic, an unsurpassed explanation of where it is we really come from.

    At the subatomic level, one particle seems to know what the others are doing, and according to Heisenberg's "uncertainty principle", there is a limit on how accurately nature can be observed. And yet the theory is amazingly accurate and widely applied, explaining all of chemistry and most of physics. "Introducing Quantum Theory" takes us on a step-by-step tour with the key figures, including Planck, Einstein, Bohr, Heisenberg and Schrodinger. Each contributed at least one crucial concept to the theory. The puzzle of the wave-particle duality is here, along with descriptions of the two questions raised against Bohr's "Copenhagen Interpretation" - the famous "dead and alive cat" and the EPR paradox. Both remain unresolved.

    The first, which describes the force of gravity, is widely known: Einstein's General Theory of Relativity. But the theory that explains everything else--the Standard Model of Elementary Particles--is virtually unknown among the general public.In The Theory of Almost Everything, Robert Oerter shows how what were once thought to be separate forces of nature were combined into a single theory by some of the most brilliant minds of the twentieth century. Rich with accessible analogies and lucid prose, The Theory of Almost Everything celebrates a heretofore unsung achievement in human knowledge--and reveals the sublime structure that underlies the world as we know it.

    What happened during those years and what has happened since to refine the understanding of this phenomenon is the fascinating story told here.We move from a coffee shop in Zurich, where Einstein and Max von Laue discuss the madness of quantum theory, to a bar in Brazil, as David Bohm and Richard Feynman chat over cervejas. We travel to the campuses of American universities—from J. Robert Oppenheimer’s Berkeley to the Princeton of Einstein and Bohm to Bell’s Stanford sabbatical—and we visit centers of European physics: Copenhagen, home to Bohr’s famous institute, and Munich, where Werner Heisenberg and Wolfgang Pauli picnic on cheese and heady discussions of electron orbits.Drawing on the papers, letters, and memoirs of the twentieth century’s greatest physicists, Louisa Gilder both humanizes and dramatizes the story by employing their own words in imagined face-to-face dialogues. Here are Bohr and Einstein clashing, and Heisenberg and Pauli deciding which mysteries to pursue. We see Schrödinger and Louis de Broglie pave the way for Bell, whose work is here given a long-overdue revisiting. And with his characteristic matter-of-fact eloquence, Richard Feynman challenges his contemporaries to make something of this entanglement.

    Isaac Asimov writes about actual and fictional scientists--from Archimedes in his bath to the alien astronomers on the far planet of Largesh--whose minds and discoveries have shaped our past, present, and future

    Written by one of the world's few practicing alchemists, it's a concise reference guide that provides easy-to-follow information so that anybody can be a wizard-in-training.

    She is also a superbly gifted writer–witty, insightful, at once deeply humane and refreshingly wry. In Another Day in the Frontal Lobe, Dr. Firlik draws on this rare combination to create a neurosurgeon’s Kitchen Confidential–a unique insider’s memoir of a fascinating profession.Neurosurgeons are renowned for their big egos and aggressive self-confidence, and Dr. Firlik confirms that timidity is indeed rare in the field. “They’re the kids who never lost at musical chairs,” she writes. A brain surgeon is not only a highly trained scientist and clinician but also a mechanic who of necessity develops an intimate, hands-on familiarity with the gray matter inside our skulls. It’s the balance between cutting-edge medical technology and manual dexterity, between instinct and expertise, that Firlik finds so appealing–and so difficult to master. Firlik recounts how her background as a surgeon’s daughter with a strong stomach and a keen interest in the brain led her to this rarefied specialty, and she describes her challenging, atypical trek from medical student to fully qualified surgeon. Among Firlik’s more memorable cases: a young roofer who walked into the hospital with a three-inch-long barbed nail driven into his forehead, the result of an accident with his partner’s nail gun, and a sweet little seven-year-old boy whose untreated earache had become a raging, potentially fatal infection of the brain lining. From OR theatrics to thorny ethical questions, from the surprisingly primitive tools in a neurosurgeon’s kit to glimpses of future techniques like the “brain lift,” Firlik cracks open medicine’s most prestigious and secretive specialty. Candid, smart, clear-eyed, and unfailingly engaging, Another Day in the Frontal Lobe is a mesmerizing behind-the-scenes glimpse into a world of incredible competition and incalculable rewards.From the Hardcover edition.
