Its author's engaging voice is one reason, and the compelling subjects he addresses is another; the nature of space and time, the role of God in creation, the history and future of the universe. But it is also true that in the years since its publication, readers have repeatedly told Professor Hawking of their great difficulty in understanding some of the book's most important concepts. This is the origin of and the reason for A Briefer History of Time: its author's wish to make its content more accessible to readers - as well as to bring it up-to-date with the latest scientific observations and findings.Although this book is literally somewhat "briefer", it actually expands on the great subjects of the original. Purely technical concepts, such as the mathematics of chaotic boundary conditions, are gone. Conversely, subjects of wide interest that were difficult to follow because they were interspersed throughout the book have now been given entire chapters of their own, including relativity, curved space, and quantum theory.This reorganization has allowed the authors to expand areas of special interest and recent progress, from the latest developments in string theory to exciting developments in the search for a complete unified theory of all the forces of physics. Like prior editions of the book - but even more so - A Briefer History of Time will guide nonscientists everywhere in the ongoing search for the tantalizing secrets at the heart of time and space. Thirty-seven full-color illustrations enhance the text and make A Briefer History of Time an exhilarating addition in its own right to the literature of science.

    Now he offers a framework for envisioning the twenty-first century--an age in which the marriage of human sensitivity and artificial intelligence fundamentally alters and improves the way we live. Kurzweil's prophetic blueprint for the future takes us through the advances that inexorably result in computers exceeding the memory capacity and computational ability of the human brain by the year 2020 (with human-level capabilities not far behind); in relationships with automated personalities who will be our teachers, companions, and lovers; and in information fed straight into our brains along direct neural pathways. Optimistic and challenging, thought-provoking and engaging, The Age of Spiritual Machines is the ultimate guide on our road into the next century.

    He believes that we should investigate what makes some countries more capable than others. Complex products—from films to robots, apps to automobiles—are a physical distillation of an economy’s knowledge, a measurable embodiment of its education, infrastructure, and capability. Economic wealth accrues when applications of this knowledge turn ideas into tangible products; the more complex its products, the more economic growth a country will experience.A radical new interpretation of global economics, Why Information Grows overturns traditional assumptions about the development of economies and the origins of wealth and takes a crucial step toward making economics less the dismal science and more the insightful one.

    When weapons builders detonated the first hydrogen bomb in 1952, they tapped into the vastest source of energy in our solar system--the very same phenomenon that makes the sun shine. Nuclear fusion was a virtually unlimited source of power that became the center of a tragic and comic quest that has left scores of scientists battered and disgraced. For the past half-century, governments and research teams have tried to bottle the sun with lasers, magnets, sound waves, particle beams, and chunks of metal, have struggled to harness the power of fusion. (The latest venture, a giant, multi-billion-dollar, international fusion project called ITER, is just now getting underway.) Again and again, they have failed, disgracing generations of scientists. Throughout this fascinating journey Charles Seife introduces us to the daring geniuses, villains, and victims of fusion science: the brilliant and tortured Andrei Sakharov; the monomaniacal and Strangelovean Edward Teller; Ronald Richter, the secretive physicist whose lies embarrassed an entire country; and Stanley Pons and Martin Fleischmann, the two chemists behind the greatest scientific fiasco of the past hundred years. Sun in a Bottle is the first major book to trace the story of fusion from its beginnings into the 21st century, of how scientists have gotten burned by trying to harness the power of the sun.

    The story of how we got from there to here is full of fascinating people, and in this elegant, entertaining book, Paul Strathern introduces us to ancient philosophers, medieval alchemists, and the earliest chemists-and to Dimitri Mendeleyev, the card-playing nineteenth-century Russian who claimed that the answers came to him in a dream. "Chemistry has been a neglected area of science writing, and Mendeleyev, the king of chemistry, is a largely forgotten genius. [This book] goes a long way toward correcting this injustice." (Simon Singh, author of Fermat's Last Theorem, in the Sunday Telegraph)

    Encyclopaedia Anatomica does just this, page after page, with its high-quality color reproductions of the collection of Florence's Museo La Specola. This amazing set of anatomical models, made mostly of wax, are so brilliantly lifelike that the casual reader is sure to mistake them for extraordinarily well-preserved bodies. Organized by anatomical section, each of hundreds of models are displayed to show off their most flattering aspect; despite the respectful attitudes held by the book editors and designers, the macabre nature of the exhibits is irrepressible. Particularly eerie are the tableaux of Gaetano Giulio Zumbo, who used similar techniques to create terrifying metaphorical portraits of the harsh life of the 18th century. While the descriptions aren't specific enough to yield much insight into the anatomical detail, this would still make an excellent companion to a text or laboratory manual. The introductory essays cover the history of the museum, the artists, and their techniques thoroughly and engagingly. If the inside of the body is as beautiful to you as the outside, you should find Encyclopaedia Anatomica a charmingly powerful work. --Rob Lightner

    Since 2000, science has seen a surge in data and interest on several fronts related to E.T. (extraterrestrials); A.I. (artificial intelligence); and SETI (search for extraterrestrial intelligence). The debate has intensified over whether life exists outside our solar system, what that life would look like, and whether we’ll ever make contact.Included here are essays from a broad spectrum of the scientific community: cosmologists, astrophysicists, NASA planetary scientists, and geneticists, to name just a few, discussing the latest research and theories relating to alien life. Some of the topics include: If life exists somewhere in space, what are the odds that it evolves into something we would recognize as intelligent? What will space travel look like in the future, and will it all be done by cyborg technology? How long until we are ruled by robot overlords? (This is actually a serious consideration.) Are we simply a simulation in the mind of some supreme being, acting out a virtual reality game?For those who have ever wondered, Is there anybody out there? here are the latest theories and evidence that move us closer to answering that question.

    Michael Hanlon identifies ten scientific questions that we simply can't seem to answer and explains why these compelling mysteries will remain unsolved for years to comeHow did life begin? Why are there two sexes? Where did language originate? In Hanlon's characteristically witty style, he ponders the ways these questions have persisted in frustrating the best minds and asks what might be needed to get to the bottom of it all. From politics to lack of technology, each question has its own set of circumstances holding it back. By exploring these unanswerable questions, Hanlon exposes some of science's greatest failings and missteps--and charts a hopeful direction for getting science back on the road to discovery.

    Sufferers report feeling suffocated, held down by some "force," paralyzed, and extremely afraid.The experience is surprisingly common: the author estimates that approximately 15 percent of people undergo this event at some point in their lives. Various cultures have their own name for the phenomenon and have constructed their own mythology around it; the supernatural tenor of many Old Hag stories is unavoidable. Hufford, as a folklorist, is well-placed to investigate this puzzling occurrence.

    Often billions of times more massive than the Sun, they lurk in the inner sanctum of almost every galaxy of stars in the universe. They're mysterious chasms so destructive and unforgiving that not even light can escape their deadly wrath.Recent research, however, has led to a cascade of new discoveries that have revealed an entirely different side to black holes. As the astrophysicist Caleb Scharf reveals in Gravity's Engines, these chasms in space-time don't just vacuum up everything that comes near them; they also spit out huge beams and clouds of matter. Black holes blow bubbles.With clarity and keen intellect, Scharf masterfully explains how these bubbles profoundly rearrange the cosmos around them. Engaging with our deepest questions about the universe, he takes us on an intimate journey through the endlessly colorful place we call our galaxy and reminds us that the Milky Way sits in a special place in the cosmic zoo—a "sweet spot" of properties. Is it coincidental that we find ourselves here at this place and time? Could there be a deeper connection between the nature of black holes and their role in the universe and the phenomenon of life? We are, after all, made of the stuff of stars.

    A lively account of our age-old quest for brighter colors, which changed the way we see the world, from the best-selling author of Proof: The Science of Booze

    In Peter Woit's view, superstring theory is just such an idea. In Not Even Wrong , he shows that what many physicists call superstring "theory" is not a theory at all. It makes no predictions, even wrong ones, and this very lack of falsifiability is what has allowed the subject to survive and flourish. Not Even Wrong explains why the mathematical conditions for progress in physics are entirely absent from superstring theory today and shows that judgments about scientific statements, which should be based on the logical consistency of argument and experimental evidence, are instead based on the eminence of those claiming to know the truth. In the face of many books from enthusiasts for string theory, this book presents the other side of the story.

    Over ninety percent of the universe consists of "missing mass" or "dark matter" - what Lawrence Krauss, in his classic book, termed "the fifth essence."In this new edition of T he Fifth Essence , retitled Quintessence after the now widely accepted term for dark matter, Krauss shows how the dark matter problem is now connected with two of the hottest areas in recent cosmology: the fate of the universe and the "cosmological constant." With a new introduction, epilogue, and chapter updates, Krauss updates his classic for 1999 and shares one of the most stunning discoveries of recent years: an anti-gravity force that explains recent observations of a permanently expanding universe.

    And liberated from its mathematical underpinnings, physics suddenly becomes accessible to anyone with the curiosity and imagination to explore its beauty. Science without math? It's not that unusual. For example, we can understand the concept of gravity without solving a single equation. So for all those who may have pondered what makes blueberries blue and strawberries red; for those who have wondered if sound really travels in waves; and why light behaves so differently from any other phenomenon in the universe, it's all a matter of quantum physics. Absolutely Small presents (and demystifies) the world of quantum science like no book before. It explores scientific concepts--from particles of light, to probability, to states of matter, to what makes greenhouse gases bad--in considerable depth, but using examples from the everyday world. Challenging without being intimidating, accessible but not condescending, Absolutely Small develops the reader's intuition for the very nature of things at their most basic and intriguing levels.

    It follows that the belief that there is a significant chance that we will one day become posthumans who run ancestor-simulations is false, unless we are currently living in a simulation. A number of other consequences of this result are also discussed.
