Gnostic writings offer striking perspectives on both early Christian and non-Christian thought. For example, some gnostic texts suggest that god should be celebrated as both mother and father, and that self-knowledge is the supreme path to the divine. Only in the past fifty years has it become clear how far the gnostic influence spread in ancient and medieval religions—and what a marvelous body of scriptures it produced. The selections gathered here, in poetic, readable translation, represent Jewish, Christian, Hermetic, Mandaean, Manichaean, Islamic, and Cathar expressions of gnostic spirituality. Their regions of origin include Egypt, the Greco-Roman world, the Middle East, Syria, Iraq, China, and France. Also included are introductions, notes, an extensive glossary, and a wealth of suggestions for further reading.

    Madison Smartt Bell’s enthralling narrative reads like a race to the finish line, as the very circumstances that enabled Lavoisier to secure his reputation as the father of modern chemistry—a considerable fortune and social connections with the likes of Benjamin Franklin—also caused his glory to be cut short by the French Revolution.

    Beginning millions of years ago with ancient “ant odometers” and moving through time to our modern-day quest for new dimensions, it covers 250 milestones in mathematical history. Among the numerous delights readers will learn about as they dip into this inviting anthology: cicada-generated prime numbers, magic squares from centuries ago, the discovery of pi and calculus, and the butterfly effect. Each topic gets a lavishly illustrated spread with stunning color art, along with formulas and concepts, fascinating facts about scientists’ lives, and real-world applications of the theorems.

    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.

    Based on selective breeding of human beings, eugenics began in laboratories on Long Island but ended in the concentration camps of Nazi Germany. Cruel and racist laws were enacted in 27 U.S. states, while the supporters of eugenics included progressive thinkers like Woodrow Wilson, Margaret Sanger and Oliver Wendell Holmes. Ultimately, over 60,000 "unfit" Americans were coercively sterilized, a third of them after Nuremberg had declared such practices crimes against humanity. This is a timely and shocking chronicle of bad science at its worst—with many important lessons for the genetic age in which an interest in eugenics has been dangerously revived.

    Using the dialogue form, a genre common in classical philosophical works, Galileo masterfully demonstrates the truth of the Copernican system over the Ptolemaic one, proving, for the first time, that the earth revolves around the sun. Its influence is incalculable. The Dialogue is not only one of the most important scientific treatises ever written, but a work of supreme clarity and accessibility, remaining as readable now as when it was first published. This edition uses the definitive text established by the University of California Press, in Stillman Drake’s translation, and includes a Foreword by Albert Einstein and a new Introduction by J. L. Heilbron.

    "It would be hard to design a more reliable timekeeper." In Nature's Clocks, Macdougall tells how scientists who were seeking to understand the past arrived at the ingenious techniques they now use to determine the age of objects and organisms. By examining radiocarbon (C-14) dating—the best known of these methods—and several other techniques that geologists use to decode the distant past, Macdougall unwraps the last century's advances, explaining how they reveal the age of our fossil ancestors such as "Lucy," the timing of the dinosaurs' extinction, and the precise ages of tiny mineral grains that date from the beginning of the earth's history. In lively and accessible prose, he describes how the science of geochronology has developed and flourished. Relating these advances through the stories of the scientists themselves—James Hutton, William Smith, Arthur Holmes, Ernest Rutherford, Willard Libby, and Clair Patterson—Macdougall shows how they used ingenuity and inspiration to construct one of modern science's most significant accomplishments: a timescale for the earth's evolution and human prehistory.

    . . a book that enriches our understanding of how the struggle to think new thoughts is shared across time and space and people.”—The Sunday Telegraph (London)Christmas, 1859. Just one month after the publication of On the Origin of Species, Charles Darwin received an unsettling letter. He had expected criticism; in fact, letters were arriving daily, most expressing outrage and accusations of heresy. But this letter was different. It accused him of failing to acknowledge his predecessors, of taking credit for a theory that had already been discovered by others. Darwin realized that he had made an error in omitting from Origin of Species any mention of his intellectual forebears. Yet when he tried to trace all of the natural philosophers who had laid the groundwork for his theory, he found that history had already forgotten many of them.Darwin’s Ghosts tells the story of the collective discovery of evolution, from Aristotle, walking the shores of Lesbos with his pupils, to Al-Jahiz, an Arab writer in the first century, from Leonardo da Vinci, searching for fossils in the mine shafts of the Tuscan hills, to Denis Diderot in Paris, exploring the origins of species while under the surveillance of the secret police, and the brilliant naturalists of the Jardin de Plantes, finding evidence for evolutionary change in the natural history collections stolen during the Napoleonic wars. Evolution was not discovered single-handedly, Rebecca Stott argues, contrary to what has become standard lore, but is an idea that emerged over many centuries, advanced by daring individuals across the globe who had the imagination to speculate on nature’s extraordinary ways, and who had the courage to articulate such speculations at a time when to do so was often considered heresy.With each chapter focusing on an early evolutionary thinker, Darwin’s Ghosts is a fascinating account of a diverse group of individuals who, despite the very real dangers of challenging a system in which everything was presumed to have been created perfectly by God, felt compelled to understand where we came from. Ultimately, Stott demonstrates, ideas—including evolution itself—evolve just as animals and plants do, by intermingling, toppling weaker notions, and developing over stretches of time. Darwin’s Ghosts presents a groundbreaking new theory of an idea that has changed our very understanding of who we are.

    In the hands of one of today’s hottest young physicists, that simple fact of breakfast becomes a doorway to understanding the Big Bang, the universe, and other universes, too. In From Eternity to Here, Sean Carroll argues that the arrow of time, pointing resolutely from the past to the future, owes its existence to conditions before the Big Bang itself, a period modern cosmology of which Einstein never dreamed. Increasingly, though, physicists are going out into realms that make the theory of relativity seem like child’s play. Carroll’s scenario is not only elegant, it’s laid out in the same easy-to- understand language that has made his group blog, Cosmic Variance, the most popular physics blog on the Net. From Eternity to Here uses ideas at the cutting edge of theoretical physics to explore how properties of spacetime before the Big Bang can explain the flow of time we experience in our everyday lives. Carroll suggests that we live in a baby universe, part of a large family of universes in which many of our siblings experience an arrow of time running in the opposite direction. It’s an ambitious, fascinating picture of the universe on an ultra-large scale, one that will captivate fans of popular physics blockbusters like Elegant Universe and A Brief History of Time.

    In this book, Peter Dear offers an accessible introduction to the origins of modern science for both students and general readers.Beginning with what was worth knowing in 1500, Dear takes the reader through natural philosophy, humanism, mathematics, and experimentalism until he can describe what was worth knowing by the eighteenth century. Along the way, he discusses the key ideas, individuals, and social changes that constituted the Scientific Revolution.For all of its economy and broad appeal, Revolutionizing the Sciences never sacrifices sophistication of treatment. Dear questions triumphal ideas of scientific progress, unravels the connections between scientific knowledge and power over nature, and distinguishes between the scientific renaissance that characterized the sixteenth century and the more fundamental revolution that occurred in the seventeenth.This is an ideal textbook on the Scientific Revolution for courses on the history of science or the history of early modern Europe. The text is chronologically arranged and fully covers both the sixteenth and seventeenth centuries, standing alone as an up-to-date, complete general introduction to the origins of modern science in Europe.Revolutionizing the Sciences is the best available choice for teaching or learning about the developments that came to be called the Scientific Revolution.

    One On One With SatanA chilling and highly convincing account of possession and exorcism in modern America, hailed by NBC Radio as "one of the most stirring books on the contemporary scene."

    In this masterfully written and brilliantly informed work of scientific history and explanation, Dr. Thorne, the Feynman Professor of Theoretical Physics at Caltech, leads his readers through an elegant, always human, tapestry of interlocking themes, coming finally to a uniquely informed answer to the great question: what principles control our universe and why do physicists think they know the things they think they know? Stephen Hawking's A Brief History of Time has been one of the greatest best-sellers in publishing history. Anyone who struggled with that book will find here a more slowly paced but equally mind-stretching experience, with the added fascination of a rich historical and human component.

    While psychedelics of all sorts are demonized in America today, the visionary compounds found in plants are the spiritual sacraments of tribal cultures around the world. From the iboga of the Bwiti in Gabon, to the Mazatecs of Mexico, these plants are sacred because they awaken the mind to other levels of awareness--to a holographic vision of the universe.Breaking Open the Head is a passionate, multilayered, and sometimes rashly personal inquiry into this deep division. On one level, Daniel Pinchbeck tells the story of the encounters between the modern consciousness of the West and these sacramental substances, including such thinkers as Allen Ginsberg, Antonin Artaud, Walter Benjamin, and Terence McKenna, and a new underground of present-day ethnobotanists, chemists, psychonauts, and philosophers. It is also a scrupulous recording of the author's wide-ranging investigation with these outlaw compounds, including a thirty-hour tribal initiation in West Africa; an all-night encounter with the master shamans of the South American rain forest; and a report from a psychedelic utopia in the Black Rock Desert that is the Burning Man Festival.Breaking Open the Head is brave participatory journalism at its best, a vivid account of psychic and intellectual experiences that opened doors in the wall of Western rationalism and completed Daniel Pinchbeck's personal transformation from a jaded Manhattan journalist to shamanic initiate and grateful citizen of the cosmos.
