His ideas spread like wildfire across Europe, offering the scientific view that the natural world, including the soul of man, was a proper subject of study. The rediscovery of these ancient ideas sparked riots and heresy trials, caused major upheavals in the Catholic Church, and also set the stage for today's rift between reason and religion. In Aristotle's Children, Richard Rubenstein transports us back in history, rendering the controversies of the Middle Ages lively and accessible-and allowing us to understand the philosophical ideas that are fundamental to modern thought.

    Together, the direct, forceful twelfth-century Grænlendinga Saga and the more polished and scholarly Eirik's Saga, written some hundred years later, recount how Eirik the Red founded an Icelandic colony in Greenland and how his son, Leif the Lucky, later sailed south to explore - and if possible exploit - the chance discovery by Bjarni Herjolfsson of an unknown land. In spare and vigorous prose they record Europe's first surprise glimpse of the eastern shores of the North American continent and the natives who inhabited them.

    Says author Daniel Pinkwater of this novel of sociological import: "I honestly don't remember writing this. Are you sure there hasn't been some mistake?"

    Oceans cover two-thirds of the earth's surface with an average depth of more than two miles--yet humans had never ventured more than a few hundred feet below the waves. One of the great scientific and archaeological feats of our time has been finally to cast light on the eternal darkness of the deep sea. This is the story of that achievement, told by the man who has done more than any other to make it possible: Robert Ballard.Ballard discovered the wreck of the Titanic. He led the teams that discovered hydrothermal vents and black smokers--cracks in the ocean floor where springs of superheated water support some of the strangest life-forms on the planet. He was a diver on the team that explored the mid-Atlantic ridge for the first time, confirming the theory of plate tectonics. Today, using a nuclear submarine from the U.S. Navy, he's exploring the ancient trade routes of the Mediterranean and the Black Sea for the remains of historic vessels and their cargo. In this book, he combines science, history, spectacular illustrations, and first-hand stories from his own expeditions in a uniquely personal account of how twentieth-century explorers have pushed back the frontiers of technology to take us into the midst of a world we could once only guess at.Ballard begins in 1930 with William Beebe and Otis Barton, pioneers of the ocean depths who made the world's first deep-sea dives in a cramped steel sphere. He introduces us to Auguste and Jacques Piccard, whose Bathyscaphdescended in 1960 to the lowest point on the ocean floor. He reviews the celebrated advances made by Jacques Cousteau. He describes his own major discoveries--from sea-floor spreading to black smokers--as well as his technical breakthroughs, including the development of remote-operated underwater vehicles and the revolutionary search techniques that led to the discovery and exploration of the Titanic, the Nazi battleship Bismarck, ancient trading vessels, and other great ships.Readers will come away with a richer understanding of history, earth science, biology, and marine technology--and a new appreciation for the remarkable men and women who have explored some of the most remote and fascinating places on the planet.

    During that time the original small band grew into a formidable army, backed by an extensive network of preceptories in the Latin West. In October 1307, the members of this seemingly invulnerable and respected Order were arrested on the orders of Philip IV, King of France and charged with serious heresies, including the denial of Christ, homosexuality and idol worship. The ensuing proceedings lasted for almost five years and culminated in the suppression of the Order. The motivations of the participants and the long-term repercussions of the trial have been the subject of intense and unresolved controversy, which still has resonances in our own time. In this new edition of his classic account, Malcolm Barber discusses the trial in the context of new work on the crusades, heresy, the papacy and the French monarchy.

    The father of English literature did not enjoy in his lifetime the literary celebrity that he has today—far from it. The middle-aged Chaucer was living in London, working as a midlevel bureaucrat and sometime poet, until a personal and professional crisis set him down the road leading to The Canterbury Tales. In the politically and economically fraught London of the late fourteenth century, Chaucer was swept up against his will in a series of disastrous events that would ultimately leave him jobless, homeless, separated from his wife, exiled from his city, and isolated in the countryside of Kent—with no more audience to hear the poetry he labored over. At the loneliest time of his life, Chaucer made the revolutionary decision to keep writing, and to write for a national audience, for posterity, and for fame. Brought expertly to life by Paul Strohm, this is the eye-opening story of the birth one of the most celebrated literary creations of the English language.

    Vividly portraying legendary and semi-legendary figures such as Lear, Cymbeline, Merlin the magician and the most famous of all British heroes, King Arthur, it is as much myth as it is history and its veracity was questioned by other medieval writers. But Geoffrey of Monmouth's powerful evocation of illustrious men and deeds captured the imagination of subsequent generations, and his influence can be traced through the works of Malory, Shakespeare, Dryden and Tennyson.

    Birds were rarely used in similar studies on the grounds that they were merely talented mimics--that they were, after all, "birdbrains." Experiments performed primarily on pigeons in Skinner boxes demonstrated capacities inferior to those of mammals; these results were thought to reflect the capacities of all birds, despite evidence suggesting that species such as jays, crows, and parrots might be capable of more impressive cognitive feats.Twenty years ago Irene Pepperberg set out to discover whether the results of the pigeon studies necessarily meant that other birds--particularly the large-brained, highly social parrots--were incapable of mastering complex cognitive concepts and the rudiments of referential speech. Her investigation and the bird at its center--a male Grey parrot named Alex--have since become almost as well known as their primate equivalents and no less a subject of fierce debate in the field of animal cognition. This book represents the long-awaited synthesis of the studies constituting one of the landmark experiments in modern comparative psychology.

    DickIn late January 2006, a young robotocist on the way to Google headquarters lost an overnight bag on a flight somewhere between Dallas and Las Vegas. In it was a fully functional head of the android replica of Philip K. Dick, cult science-fiction writer and counterculture guru. It has never been recovered.In a story that echoes some of the most paranoid fantasies of a Dick novel, readers get a fascinating inside look at the scientists and technology that made this amazing android possible. The author, who was a fellow researcher at the University of Memphis Institute of Intelligent Systems while the android was being built, introduces readers to the cutting-edge technology in robotics, artificial intelligence, and sculpture that came together in this remarkable machine and captured the imagination of scientists, artists, and science-fiction fans alike. And there are great stories about Dick himself his inspired yet deeply pessimistic worldview, his bizarre lifestyle, and his enduring creative legacy. In the tradition of popular science classics like "Packing for Mars" and "The Disappearing Spoon," "How to Build an Android" is entertaining and informative popular science at its best."

    It looks at medieval times from the point of view of those men and women who either would not or could not conform to the conventions of a society whose insistence upon conformity was obsessive.

    

    Carlo Ginzburg uses the trial records of Domenico Scandella, a miller also known as Menocchio, to show how one person responded to the confusing political and religious conditions of his time.For a common miller, Menocchio was surprisingly literate. In his trial testimony he made references to more than a dozen books, including the Bible, Boccaccio's Decameron, Mandeville's Travels, and a "mysterious" book that may have been the Koran. And what he read he recast in terms familiar to him, as in his own version of the creation: "All was chaos, that is earth, air, water, and fire were mixed together; and of that bulk a mass formed—just as cheese is made out of milk—and worms appeared in it, and these were the angels."

    At the center of a triangle of Anglo Saxons, Vikings, and Normans all jostling for control of England, Emma was a political pawn who became an unscrupulous manipulator. Regarded by her contemporaries as a generous Christian patron, an admired regent, and a Machiavellian mother, Emma was, above all, a survivor: hers was a life marked by dramatic reversals of fortune, all of which she overcame.

    Since then, a number of historians have built on Jonathan Riley-Smith's original conclusions. Now in its fourth edition, this classic starting point for the study of the crusading movement has been updated to take into account the latest developments in the field.What Were the Crusades?   elucidates key ideas and institutions which have been neglected in the past   demonstrates, through the analysis of European campaigns, that the movement was not confined to expeditions launched to recover the Holy Land - or to defend the Christian presence there - and shows that it continued, in one form or another, into the eighteenth century and perhaps beyond   draws attention to the increasing interest of historians in the motivation of crusaders   now includes material on a child crusader and concludes with a short discussion of the current effects of aggressive Pan-Islamism   features a new map illustrating the different theatres of war       Original in its conception, this essential guide is a contribution of major importance to crusading scholarship. In its clear and concise treatment of the issues, it remains an unequalled introduction to the subject for students and general readers alike.

    To its contemporaries, the event was a journey and the men who took part in it pilgrims. Only later were those participants dubbed Crusaders--"those signed with the Cross." In fact, many developments wit
