For millennia Europeans believed that the world consisted of three parts: Europe, Africa, and Asia. They drew the three continents in countless shapes and sizes on their maps, but occasionally they hinted at the existence of a "fourth part of the world," a mysterious, inaccessible place, separated from the rest by a vast expanse of ocean. It was a land of myth--until 1507, that is, when Martin Waldseemuller and Matthias Ringmann, two obscure scholars working in the mountains of eastern France, made it real. Columbus had died the year before convinced that he had sailed to Asia, but Waldseemuller and Ringmann, after reading about the Atlantic discoveries of Columbus's contemporary Amerigo Vespucci, came to a startling conclusion: Vespucci had reached the fourth part of the world. To celebrate his achievement, Waldseemuller and Ringmann printed a huge map, for the first time showing the New World surrounded by water and distinct from Asia, and in Vespucci's honor they gave this New World a name: America."The Fourth Part of the World "is the story behind that map, a thrilling saga of geographical and intellectual exploration, full of outsize thinkers and voyages. Taking a kaleidoscopic approach, Toby Lester traces the origins of our modern worldview. His narrative sweeps across continents and centuries, zeroing in on different portions of the map to reveal strands of ancient legend, Biblical prophecy, classical learning, medieval exploration, imperial ambitions, and more. In Lester's telling the map comes alive: Marco Polo and the early Christian missionaries trek across Central Asia and China; Europe's early humanists travel to monastic libraries to recover ancient texts; Portuguese merchants round up the first West African slaves; Christopher Columbus and Amerigo Vespucci make their epic voyages of discovery; and finally, vitally, Nicholas Copernicus makes an appearance, deducing from the new geography shown on the Waldseemuller map that the earth could not lie at the center of the cosmos. The map literally altered humanity's worldview.One thousand copies of the map were printed, yet only one remains. Discovered accidentally in 1901 in the library of a German castle it was bought in 2003 for the unprecedented sum of $10 million by the Library of Congress, where it is now on permanent public display. Lavishly illustrated with rare maps and diagrams, "The Fourth Part of the World "is the story of that map: the dazzling story of the geographical and intellectual journeys that have helped us decipher our world.

    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.

    Einstein famously quipped that God does not play dice with the universe, and Schrödinger is equally well known for his thought experiment about the cat in the box who ends up “spread out” in a probabilistic state, neither wholly alive nor wholly dead. Both of these famous images arose from these two men’s dissatisfaction with quantum weirdness and with their assertion that underneath it all, there must be some essentially deterministic world. Even though it was Einstein’s own theories that made quantum mechanics possible, both he and Schrödinger could not bear the idea that the universe was, at its most fundamental level, random.As the Second World War raged, both men struggled to produce a theory that would describe in full the universe’s ultimate design, first as collaborators, then as competitors. They both ultimately failed in their search for a Grand Unified Theory—not only because quantum mechanics is true, but because Einstein and Schrödinger were also missing a key component: of the four forces we recognize today (gravity, electromagnetism, the weak force, and the strong force), only gravity and electromagnetism were known at the time.Despite their failures, though, much of modern physics remains focused on the search for a Grand Unified Theory. As Halpern explains, the recent discovery of the Higgs Boson makes the Standard Model—the closest thing we have to a unified theory—nearly complete. And while Einstein and Schrödinger tried and failed to explain everything in the cosmos through pure geometry, the development of string theory has, in its own quantum way, brought this idea back into vogue. As in so many things, even when he was wrong, Einstein couldn’t help but be right.

    In movies, in novels, in comic strips, and on television, we’ve all seen dinosaurs—or at least somebody’s educated guess of what they would look like. But what if it were possible to build, or grow, a real dinosaur, without finding ancient DNA? Jack Horner, the scientist who advised Steven Spielberg on Jurassic Park, and a pioneer in bringing paleontology into the twenty-first century, teams up with the editor of The New York Times’s Science Times section to reveal exactly what’s in store. In the 1980s, Horner began using CAT scans to look inside fossilized dinosaur eggs, and he and his colleagues have been delving deeper ever since. At North Carolina State University, Mary Schweitzer has extracted fossil molecules—proteins that survived 68 million years—from a Tyrannosaurus rex fossil excavated by Horner. These proteins show that T. rex and the modern chicken are kissing cousins. At McGill University, Hans Larsson is manipulating a chicken embryo to awaken the dinosaur within: starting by growing a tail and eventually prompting it to grow the forelimbs of a dinosaur. All of this is happening without changing a single gene. This incredible research is leading to discoveries and applications so profound they’re scary in the power they confer on humanity. How to Build a Dinosaur is a tour of the hot rocky deserts and air-conditioned laboratories at the forefront of this scientific revolution.

    Most know Richard Feynman for the hilarious anecdotes and exploits in his best-selling books Surely You're Joking, Mr. Feynman! and What DoYou Care What Other People Think? But not always obvious in those stories was his brilliance as a pure scientist—one of the century's greatest physicists. With this book and CD, we hear the voice of the great Feynman in all his ingenuity, insight, and acumen for argument. This breathtaking lecture—"The Motion of the Planets Around the Sun"—uses nothing more advanced than high-school geometry to explain why the planets orbit the sun elliptically rather than in perfect circles, and conclusively demonstrates the astonishing fact that has mystified and intrigued thinkers since Newton: Nature obeys mathematics. David and Judith Goodstein give us a beautifully written short memoir of life with Feynman, provide meticulous commentary on the lecture itself, and relate the exciting story of their effort to chase down one of Feynman's most original and scintillating lectures.

    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.

    Randall Fuller takes us back to one of those turning points, in 1860, with the story of the influence of Charles Darwin's just-published On the Origin of Species on five American intellectuals, including Bronson Alcott, Henry David Thoreau, the child welfare reformer Charles Loring Brace, and the abolitionist Franklin Sanborn.Each of these figures seized on the book's assertion of a common ancestry for all creatures as a powerful argument against slavery, one that helped provide scientific credibility to the cause of abolition. Darwin's depiction of constant struggle and endless competition described America on the brink of civil war. But some had difficulty aligning the new theory to their religious convictions and their faith in a higher power. Thoreau, perhaps the most profoundly affected all, absorbed Darwin's views into his mysterious final work on species migration and the interconnectedness of all living things.Creating a rich tableau of nineteenth-century American intellectual culture, as well as providing a fascinating biography of perhaps the single most important idea of that time, The Book That Changed America is also an account of issues and concerns still with us today, including racism and the enduring conflict between science and religion.

    Indeed, as Tom Standage reveals in his scintillating new book, social media is anything but a new phenomenon.From the papyrus letters that Roman statesmen used to exchange news across the Empire to the advent of hand-printed tracts of the Reformation to the pamphlets that spread propaganda during the American and French revolutions, Standage chronicles the increasingly sophisticated ways people shared information with each other, spontaneously and organically, down the centuries. With the rise of newspapers in the nineteenth century, then radio and television, “mass media” consolidated control of information in the hands of a few moguls. However, the Internet has brought information sharing full circle, and the spreading of news along social networks has reemerged in powerful new ways.A fresh, provocative exploration of social media over two millennia, Writing on the Wall reminds us how modern behavior echoes that of prior centuries-the Catholic Church, for example, faced similar dilemmas in deciding whether or how to respond to Martin Luther's attacks in the early sixteenth century to those that large institutions confront today in responding to public criticism on the Internet. Invoking the likes of Thomas Paine and Vinton Cerf, co-inventor of the Internet, Standage explores themes that have long been debated: the tension between freedom of expression and censorship; whether social media trivializes, coarsens or enhances public discourse; and its role in spurring innovation, enabling self-promotion, and fomenting revolution. As engaging as it is visionary, Writing on the Wall draws on history to cast new light on today's social media and encourages debate and discussion about how we'll communicate in the future.

    Pulitzer Prize-winning astronomer Carl Sagan, author of Cosmos and Contact, and writer Ann Druyan explore the origin, nature, and future of comets, and the exotic myths and portents attached to them. The authors show how comets have spurred some of the great discoveries in the history of science and raise intriguing questions about these brilliant visitors from the interstellar dark.Were the fates of the dinosaurs and the origins of humans tied to the wanderings of a comet? Are comets the building blocks from which worlds are formed?Lavishly illustrated with photographs and specially commissioned full-color paintings, Comet is an enthralling adventure, indispensable for anyone who has ever gazed up at the heavens and wondered why."SIMPLY THE BEST." *The Times of London"FASCINATING, EVOCATIVE, INSPIRING." *The Washington Post"COMET HUMANIZES SCIENCE.

    The name dinosaur was coined in 1842 by an English anatomist Richard Owen, a highly ambitious, machiavellian schemer and villain of Deborah Cadbury's The Dinosaur Hunters: A True Story of Scientific Rivalry and the Discovery of the Prehistoric World. Her hero is Gideon Mantell, a practising doctor, who found and first described many of the bones of the beasts that subsequently became known as dinosaurs. Full of quotes from contemporary sources, The Dinosaur Hunters brilliantly evokes the Dickensian world of early Victorian science and society. From Mary Anning, the self-taught fossil hunter of Lyme Regis to the academic and deeply eccentric Dean Buckland of Oxford University, the story tells of reputations made and lost as self-help, self-promotion, over-wheening pride, folly and social climbing all played their part in the emerging story of the geological past. The dinosaurs, although central to the story, are also a vehicle for the much larger, more interesting and important story about the struggle to understand the meaning of fossils and what they tell us about prehistory. Deborah Cadbury, an award-winning TV science producer and acclaimed author of The Feminisation of Nature has thoroughly researched her topic and steeped herself in the intricacies of the scientific debates of the time. With black and white illustrations, extensive notes, a bibliography and index, the result is one of the best popular science histories. --Douglas Palmer.

    Far less well-known is a much greater catastrophe that took place at the end of the Permian period 251 million years ago: 90 percent of life was destroyed, including saber-toothed reptiles and their rhinoceros-sized prey on land, as well as vast numbers of fish and other species in the sea.This book documents not only what happened during this gigantic mass extinction but also the recent rekindling of the idea of catastrophism. Was the end-Permian event caused by the impact of a huge meteorite or comet, or by prolonged volcanic eruption in Siberia? The evidence has been accumulating through the 1990s and into the new millennium, and Michael Benton gives his verdict at the very end. From field camps in Greenland and Russia to the laboratory bench, When Life Nearly Died involves geologists, paleontologists, environmental modelers, geochemists, astronomers, and experts on biodiversity and conservation. Their working methods are vividly described and explained, and the current disputes are revealed. The implications of our understanding of crises in the past for the current biodiversity crisis are also presented in detail. 46 b/w illustrations.

    “A marvelously readable and level-headed explanation of basic science and how it relates to the issues.” —John Tierney, New York TimesThis is “must-have” information for all presidents—and citizens—of the twenty-first century: Is Iran’s nascent nuclear capability a genuine threat to the West? Are biochemical weapons likely to be developed by terrorists? Are there viable alternatives to fossil fuels that should be nurtured and supported by the government? Should nuclear power be encouraged? Can global warming be stopped?

    With lively anecdotes and vivid detail, The Madame Curie Complex reveals how women scientists have often asked different questions, used different methods, come up with different explanations for phenomena in the natural world, and how they have forever transformed a scientist's role.
