Timothy Ferris provides a clear, elegantly written overview of current research and a forecast of where cosmological theory is likely to go in the twenty-first century. He explores the questions that have occurred to even casual readers -- who are curious about nature on the largest scales: What does it mean to say that the universe is "expanding," or that space is "curved"? -- and sheds light on the possibility that our universe is only one among many universes, each with its own physical laws and prospects for the emergence of life.

    This seminal work is reproduced here for a whole new generation to enjoy. In Sagan's typically lucid and lyrical style, he discusses many topics from astrophysics and solar system science, to colonization, terraforming and the search for extraterrestrials. Sagan conveys his own excitement and wonder, and relates the revelations of astronomy to the most profound human problems and concerns: issues that are just as valid today as they were thirty years ago. New to this edition are Freeman Dyson's comments on Sagan's vision and the importance of the work, Ann Druyan's assessment of Sagan's cultural significance as a champion of science, and David Morrison's discussion of the advances made since 1973 and what became of Sagan's predictions. Who knows what wonders this third millennium will reveal, but one thing is certain: Carl Sagan played a unique role in preparing us for them.

    Thus began one of the boldest scientific projects in history, the Search for Extraterrestrial Intelligence (SETI). But after a half century of scanning the skies, astronomers have little to report but an eerie silence—eerie because many scientists are convinced that the universe is teeming with life. The problem, argues the leading physicist-astrobiologist Paul Davies, is that we’ve been looking in the wrong place, at the wrong time & in the wrong way. Davies should know. For more than three decades, he's been closely involved with SETI & now chairs its Post-Detection Taskgroup, charged with deciding what to do if we’re confronted with evidence of alien intelligence. In this extraordinary book, he shows how SETI has lost its edge & offers a new exciting road map for the future. Davies believes our search so far has been overly anthropocentric: we tend to assume an alien species will look, think & behave like us. He argues that we need to be far more expansive in our efforts, & in this book he completely redefines the search, challenging existing ideas of what form an alien intelligence might take, how it might try to communicate with us & how we should respond if it does. A provocative & mind-expanding journey, The Eerie Silence will thrill fans of science & science fiction alike.

    Gleick's story begins at the turn of the twentieth century with the young H. G. Wells writing and rewriting the fantastic tale that became his first book, an international sensation, The Time Machine. A host of forces were converging to transmute the human understanding of time, some philosophical and some technological the electric telegraph, the steam railroad, the discovery of buried civilizations, and the perfection of clocks. Gleick tracks the evolution of time travel as an idea in the culture from Marcel Proust to Doctor Who, from Woody Allen to Jorge Luis Borges. He explores the inevitable looping paradoxes and examines the porous boundary between pulp fiction and modern physics. Finally, he delves into a temporal shift that is unsettling our own moment: the instantaneous wired world, with its all-consuming present and vanishing future.

    He looks at the difficult dialogue between science and religion; the conflict between our human desire for permanence and the impermanence of nature; the possibility that our universe is simply an accident; the manner in which modern technology has separated us from direct experience of the world; and our resistance to the view that our bodies and minds can be explained by scientific logic and laws. And behind all of these considerations is the suggestion—at once haunting and exhilarating—that what we see and understand of the world is only a tiny piece of the extraordinary, perhaps unfathomable whole.

    But are there limits to what we can discover about our physical universe?In this very personal journey to the edges of knowledge, Marcus du Sautoy investigates how leading experts in fields from quantum physics and cosmology, to sensory perception and neuroscience, have articulated the current lie of the land. In doing so, he travels to the very boundaries of understanding, questioning contradictory stories and consulting cutting edge data.Is it possible that we will one day know everything? Or are there fields of research that will always lie beyond the bounds of human comprehension? And if so, how do we cope with living in a universe where there are things that will forever transcend our understanding?In What We Cannot Know, Marcus du Sautoy leads us on a thought-provoking expedition to the furthest reaches of modern science. Prepare to be taken to the edge of knowledge to find out if there’s anything we truly cannot know.

    13 extraordinary essays shed new light on the mysteries of the universe & on one of the most brilliant thinkers of our time.In his phenomenal bestseller A Brief History of Time, Stephen Hawking literally transformed the way we think about physics, the universe, reality itself. In these thirteen essays and one remarkable extended interview, the man widely regarded as the most brilliant theoretical physicist since Einstein returns to reveal an amazing array of possibilities for understanding our universe. Building on his earlier work, Hawking discusses imaginary time, how black holes can give birth to baby universes, and scientists’ efforts to find a complete unified theory that would predict everything in the universe. With his characteristic mastery of language, his sense of humor and commitment to plain speaking, Stephen Hawking invites us to know him better—and to share his passion for the voyage of intellect and imagination that has opened new ways to understanding the very nature of the cosmos.

    Based on the premise that all human beings are curious about their existence, Rosen's collection brings together primary excerpts from the works of prominent thinkers such as Plato, Nietzsche, Descartes, Machiavelli, and Kant. Experts in each field have carefully selected the sources and provided brief introductions to help readers gain insight into the readings. Newly revised in order to emphasize its broad appeal, The Philosopher's Handbook is a solid introduction to Western philosophy for all inquiring minds.

    The author shows that no matter how bizarre a people's behavior may seem, it always stems from concrete social and economic conditions. It is by isolating and identifying these conditions that we will be able to understand and cope with some of our own apparently senseless life styles. In a devastating attack on the shamans of the counterculture, the author states the case for a return to objective consciousness and a rational set of political commitments.

    From the Senate, SATs, and sex, to crime, celebrities, and cults, he takes stories that may not seem to involvemathematics at all and demonstrates how a lack of mathematical knowledge canhinder our understanding of them.After reading A Mathematician Reads the Newspaper, it will beimpossible to look at the newspaper in the same way.-- PhiladelphiaInquirer It would be great to have John Allen Paulos living next door. Everymorning when you read the paper and come across some story that didn't seemquite right--that had the faint odor of illogic hovering about it-- you couldjust lean out the window and shout, 'John! Get the hell over here!'. A fun, spunky, wise little book that would be helpful to both the consumers of thenews and its purveyors. -- Washington Post Book World

    Here we go again with real life and opinions made to look like one big, preposterous animal not unlike an invention by Dr. Seuss...--Kurt Vonnegut, from Fates Worse Than Death

    Luminous, witty, and provocative, the essays address such topics as "The Attic of the Brain," "Falsity and Failure," "Altruism," and the effects the federal government's virtual abandonment of support for basic scientific research will have on medicine and science.Profoundly and powerfully, Thomas questions the folly of nuclear weaponry, showing that the brainpower and money spent on this endeavor are needed much more urgently for the basic science we have abandoned--and that even medicine's most advanced procedures would be useless or insufficient in the face of the smallest nuclear detonation. And in the title essay, he addresses himself with terrifying poignancy to the question of what it is like to be young in the nuclear age."If Wordsworth had gone to medical school, he might have produced something very like the essays of Lewis Thomas."--TIME "No one better exemplifies what modern medicine can be than Lewis Thomas."--The New York Times Book Review

    From submarine cables to fiber optics to neutrino and tachyon (faster than light) communications, he traces the global changes these innovations left or will leave in their wake.

    His works have been translated into every major language, and the Nobel Prize awarded to him in 1954 recognized his impact on contemporary writing. While many people are familiar with the public image of Hemingway and the legendary accounts of his life, few knew him as an intimate. With this collection of letters, presented for the first time as a Scribner Classic, a new Hemingway emerges. Ranging from 1917 to 1961, this generous selection of nearly six hundred letters is, in effect, both a self-portrait and an autobiography. In his own words, Hemingway candidly reveals himself to a wide variety of people: family, friends, enemies, editors, translators, and almost all the prominent writers of his day. In so doing he proves to be one of the most entertaining letter writers of all time. Carlos Baker has chosen letters that not only represent major turning points in Hemingway's career but also exhibit character, wit, and the writer's typical enthusiasm for hunting, fishing, drinking, and eating. A few are ingratiating, some downright truculent. Others present his views on writing and reading, criticize books by friend or foe, and discuss women, soldiers, politicians, and prizefighters. Perhaps more than anything, these letters show Hemingway's irrepressible humor, given far freer rein in his correspondence than in his books. An informal biography in letters, the product of forty-five years' living and writing, Ernest Hemingway: Selected Letters leaves an indelible impression of an extraordinary man. Ernest Hemingway was born in Oak Park, Illinois, in 1899. At seventeen he left home to join the Kansas City Star as a reporter, then volunteered to serve in the Red Cross during the First World War. He was severely wounded at the Italian front and was awarded the Croce di Guerra. He moved to Paris in 1921, where he devoted himself to writing fiction, and where he fell in with the expatriate circle that included Gertrude Stein, F. Scott Fitzgerald, Ezra Pound, and Ford Madox Ford. His novels include The Sun Also Rises (1926), A Farewell to Arms (1929), To Have and Have Not (1937), For Whom the Bell Tolls (1940), and The Old Man and the Sea (1952). He was awarded the Nobel Prize for literature in 1954. He died in Ketchum, Idaho, on July 2, 1961.

    Breaking down the symbols themselves, they pose a series of questions: What is energy? What is mass? What has the speed of light got to do with energy and mass? In answering these questions, they take us to the site of one of the largest scientific experiments ever conducted. Lying beneath the city of Geneva, straddling the Franco-Swiss boarder, is a 27 km particle accelerator, known as the Large Hadron Collider. Using this gigantic machine—which can recreate conditions in the early Universe fractions of a second after the Big Bang—Cox and Forshaw will describe the current theory behind the origin of mass.Alongside questions of energy and mass, they will consider the third, and perhaps, most intriguing element of the equation: 'c' - or the speed of light. Why is it that the speed of light is the exchange rate? Answering this question is at the heart of the investigation as the authors demonstrate how, in order to truly understand why E=mc2, we first must understand why we must move forward in time and not backwards and how objects in our 3-dimensional world actually move in 4-dimensional space-time. In other words, how the very fabric of our world is constructed. A collaboration between two of the youngest professors in the UK, Why Does E=mc2? promises to be one of the most exciting and accessible explanations of the theory of relativity in recent years.
