A rapturous guide through five major Ice Age sites” (Archaeology).   The cave art of France’s Dordogne region is world-famous for the mythology and beauty of its remarkable drawings and paintings. These ancient images of lively bison, horses, and mammoths, as well as symbols of all kinds, are fascinating touchstones in the development of human culture, demonstrating how far humankind has come and reminding us of the ties that bind us across the ages.   Over more than twenty-five years of teaching and research, Christine Desdemaines-Hugon has become an unrivaled expert in the cave art and artists of the Dordogne region. In Stepping-Stones she combines her expertise in both art and archaeology to convey an intimate understanding of the “cave experience.” Her keen insights communicate not only the incomparable artistic value of these works but also the near-spiritual impact of viewing them for oneself.   Focusing on five fascinating sites, including the famed Font de Gaume and others that still remain open to the public, this book reveals striking similarities between art forms of the Paleolithic and works of modern artists and gives us a unique pathway toward understanding the culture of the Dordogne Paleolithic peoples and how it still touches our lives today.   “Her vivid descriptions help readers visualize the Cro-Magnon man or woman painting the beautiful bison, horses, mammoths, and other symbols. [A] fine reading experience.” —Library Journal

    The ice sheet that covers it is 700 miles wide and 1,500 miles long, and is composed of nearly three quadrillion tons of ice. For the last 150 years, explorers and scientists have sought to understand Greenland--at first hoping that it would serve as a gateway to the North Pole, and later coming to realize that it contained essential information about our climate. Locked within this vast and frozen white desert are some of the most profound secrets about our planet and its future. Greenland's ice doesn't just tell us where we've been. More urgently, it tells us where we're headed.In The Ice at the End of the World, Jon Gertner explains how Greenland has evolved from one of earth's last frontiers to its largest scientific laboratory. The history of Greenland's ice begins with the explorers who arrived here at the turn of the twentieth century--first on foot, then on skis, then on crude, motorized sleds--and embarked on grueling expeditions that took as long as a year and often ended in frostbitten tragedy. Their original goal was simple: to conquer Greenland's seemingly infinite interior. Yet their efforts eventually gave way to scientists who built lonely encampments out on the ice and began drilling--one mile, two miles down. Their aim was to pull up ice cores that could reveal the deepest mysteries of earth's past, going back hundreds of thousands of years.Today, scientists from all over the world are deploying every technological tool available to uncover the secrets of this frozen island before it's too late. As Greenland's ice melts and runs off into the sea, it not only threatens to affect hundreds of millions of people who live in coastal areas. It will also have drastic effects on ocean currents, weather systems, economies, and migration patterns.Gertner chronicles the unfathomable hardships, amazing discoveries, and scientific achievements of the Arctic's explorers and researchers with a transporting, deeply intelligent style--and a keen sense of what this work means for the rest of us. The melting ice sheet in Greenland is, in a way, an analog for time. It contains the past. It reflects the present. It can also tell us how much time we might have left.

    He worked with - and relaxed with - scientific giants of that time such as Edward Teller, Enrico Fermi, Stan Ulam, John von Neumann, and John Wheeler, and here offers illuminating insights into the personalities, the strengths, and the quirks of these men. Well known for his ability to explain physics to nonspecialists, Ford also brings to life the physics of fission and fusion and provides a brief history of nuclear science from the discovery of radioactivity in 1896 to the ten-megaton explosion of “Mike” that obliterated a Pacific Island in 1952. Ford worked at both Los Alamos and Princeton's Project Matterhorn, and brings out Matterhorn's major, but previously unheralded contribution to the development of the H bomb. Outside the lab, he drove a battered Chevrolet around New Mexico, a bantam motorcycle across the country, and a British roadster around New Jersey. Part of the charm of Ford's book is the way in which he leavens his well-researched descriptions of the scientific work with brief tales of his life away from weapons.Contents: The Big Idea The Protagonists The Choice The Scientists, the Officials, and the President Nuclear Energy Some Physics Going West A New World The Classical Super Calculating and Testing Constructing Matterhorn Academia Cowers New Mexico, New York, and New Jersey The Garwin Design Climbing Matterhorn It's More Than a Boy Readership: A memoir for general readership in the history of science.Key Features: It contains real physics, clearly presented for non-specialists Combining historical scholarship and his own recollections, the author offers important insights into the people and the work that led to the first H bomb Personal anecdotes enliven the book

    The subsequent investigation was a maze of politics, bizarre theories, and shrouded answers. Bill Adair, an award-winning journalist, was granted special access to the five-year inquiry by the National Transportation Safety Board (NTSB) while its investigators tried to determine if the world's most widely used commercial jet, the Boeing 737, was really safe. Their findings have had wide-ranging effects on the airline industry, pilots, and even passangers. Adair takes readers behind the scenes to show who makes decisions about airline safety--and why.

    . . Patterson's book must now be considered the definitive Tsavo lion study... one of the world's leading experts on lions as well as an important conservationist.--Publishers WeeklyThrough field research and forensic evidence, a scientist reveals his theory on why two Kenyan lions killed humans and then ate their preyIn March 1898, the British began building a bridge over the Tsavo River in East Africa. In nine months, two male lions killed and ate nearly 135 workers, halting construction.After a long hunt Colonel J. H. Patterson killed the lions, which are now on display at the Field Museum of Natural History in Chicago.As codirector of the Tsavo Research Project, Bruce Patterson has conducted extensive fieldwork throughout the region on these lions. In The Lions of Tsavo, Patterson retells the harrowing story of those bloody nights in Kenya. He presents new forensic evidence on these maneless lions and argues that the man-eating behavior exhibited in 1898 came from the encroachment of human populations on wild habitats.Patterson continues this theory by exploring man's interaction with the changing Kenyan environment, creating a complete, up-to-date, and scientific look behind this intriguing murder mystery.

    Buried there lie answers about the origins of humankind. After a century of investigation, scientists have transformed our understanding about the beginnings of human life. But vital clues still remain hidden. In Born in Africa, Martin Meredith follows the trail of discoveries about human origins made by scientists over the last hundred years, recounting their intense rivalry, personal feuds, and fierce controversies as well as their feats of skill and endurance.The results have been momentous. Scientists have identified more than twenty species of extinct humans. They have firmly established Africa as the birthplace not only of humankind but also of modern humans. They have revealed how early technology, language ability, and artistic endeavour all originated in Africa; and they have shown how small groups of Africans spread out from Africa in an exodus sixty thousand years ago to populate the rest of the world. We have all inherited an African past.

    Mackenzie travelled by bark canoe and had a cache of rum and a crew of Canadian voyageurs, hard-living backwoodsmen, for company. Two centuries later, in a spirit of organic authenticity, Robert Twigger follows in Mackenzie's wake. He too travels the traditional way, having painstakingly built a canoe from birch bark sewn together with pine roots, and assembled a crew made up of fellow travellers, ex-tree-planters and a former sailor from the US Navy. After the ice has melted, Twigger and his crew of wandering spirits finally nose out into the Athabasca River . . . Three Years . . . two thousand miles . . .over one thousand painfully towing the canoe against the current . . . several had tried before them but they were the first people to successfully complete Mackenzie's diabolical route over the Rockies in a birch bark canoe since 1793. Subsisting on a diet of porridge, elk and jackfish, supplemented with whisky and a bag of grass for the tree planters, and with an Indian medicine charm bestowed by the Cree People of Fox Lake, the voyageurs embark on an epic road trip by canoe . . . a journey to the remotest parts of the wilderness, through Native American reservations, over mountains, through rapids and across lakes, meeting descendants of Mackenzie and unhinged Canadian trappers, running out of food, getting lost and miraculously found again, disfigured for life (the ex-sailor loses his thumb), bears brown and black, docile and grizzly. Voyageur is a moving tale of contrasts from the bleak industrial backwaters of Canada to the desolate wonder of the Rocky Mountains.

    More than 3 billion miles from Earth, a small NASA spacecraft called New Horizons screamed past Pluto at more than 32,000 miles per hour, focusing its instruments on the long mysterious icy worlds of the Pluto system, and then, just as quickly, continued on its journey out into the beyond.Nothing like this has occurred in a generation--a raw exploration of new worlds unparalleled since NASA's Voyager missions to Uranus and Neptune--and nothing like it is planned to happen ever again. The photos that New Horizons sent back to Earth graced the front pages of newspapers on all 7 continents, and NASA's website for the mission received more than 2 billion hits in the days surrounding the flyby. At a time when so many think our most historic achievements are in the past, the most distant planetary exploration ever attempted not only succeeded but made history and captured the world's imagination.How did this happen? Chasing New Horizons is the story of the men and women behind the mission: of their decades-long commitment; of the political fights within and outside of NASA; of the sheer human ingenuity it took to design, build, and fly the mission; and of the plans for New Horizons' next encounter, 1 billion miles past Pluto. Told from the insider's perspective of Dr. Alan Stern--the man who led the mission--Chasing New Horizons is a riveting story of scientific discovery, and of how far humanity can go when people focused on a dream work together toward their incredible goal.

    . . sex. The anthropology student hesitated when her boyfriend suggested she apply for a job, but apply she did, and it wasn’t long before a part-time position at New York’s MUSEUM OF SEX lead to a gig as the museum's curator. That was over twelve years ago. Now Sarah—a married mother of two—proudly sports her title as Curator of Sex. In SEX IN THE MUSEUM, Sarah invites readers to travel from suburban garages where men and women build sex machines, to factories that make sex toys, to labyrinthine archives of erotica collectors. Escorting us in to the hidden world of sex, illuminating the never-talked-about communities and eccentricities of our sexual subcultures, and telling her own personal story of a decade at The Museum of Sex, Sarah asks readers to grapple with the same questions she did: when it comes to sex, what is good, bad, deviant, normal? Do such terms even apply? If everyone has sexual secrets, is it possible to really know another person and be known by them? And importantly, in our hyper-sexualized world, is it still possible to fall in love?

    Along the way, he provides in-depth portraits of some of the great geniuses of our time, including Albert Einstein, Richard Feynman, Edward Teller, and astronomer Vera Rubin. Thoughtful, beautifully written, and wonderfully original, A Sense of the Mysterious confirms Alan Lightman's unique position at the crossroads of science and art.

    And before there were fish in the sea, there were cephalopods - the ancestors of modern squid and Earth’s first truly substantial animals. Cephalopods became the first creatures to rise from the seafloor, essentially inventing the act of swimming. With dozens of tentacles and formidable shells, they presided over an undersea empire for millions of years. But when fish evolved jaws, the ocean’s former top predator became its most delicious snack. Cephalopods had to step up their game. Many species streamlined their shells and added defensive spines, but these enhancements only provided a brief advantage. Some cephalopods then abandoned the shell entirely, which opened the gates to a flood of evolutionary innovations: masterful camouflage, fin-supplemented jet propulsion, perhaps even dolphin-like intelligence. Squid Empire is an epic adventure spanning hundreds of millions of years, from the marine life of the primordial ocean to the calamari on tonight’s menu. Anyone who enjoys the undersea world—along with all those obsessed with things prehistoric—will be interested in the sometimes enormous, often bizarre creatures that ruled the seas long before the first dinosaurs.

    Now, using never-before-published quotes taken from his in-depth interviews with twenty-three of the twenty-four Apollo lunar astronauts, Chaikin and his collaborator, Victoria Kohl, have created an extraordinary account of the lunar missions. In Voices from the Moon the astronauts vividly recount their experiences in intimate detail; their distinct personalities and remarkably varied perspectives emerge from their candid and deeply personal reflections. Carefully assembled into a narrative that reflects the entire arc of the lunar journey, Voices from the Moon captures the magnificence of the Apollo program like no other book. Paired with their own words are 160 images taken from NASA's new high-resolution scans of the photos the astronauts took during the missions. Many of the photos, which are reproduced with stunning and unprecedented detail, have rarely-if ever-been seen by the general public. Voices from the Moon is an utterly unique chronicle of these defining moments in human history.

    G. Lord was becoming a teenager in Southern California and her mother was dying of cancer, Lord's father-an archetypal, remote, rocket engineer- disappeared into his work at the Jet Propulsion Laboratory in Pasadena, building the space probes of the Mariner Mars 69 mission. Thirty years later, Lord found herself reporting on the JPL, triggering childhood memories and a desire to revisit her past as a way of understanding the ethos of rocket science. Astro Turf is the brilliant result of her journey of discovery.Remembering her pain at her father's absence, yet intrigued by what he did, Lord captures him on the page as she recalls her own youthful, eccentric fascination with science and space exploration. Into her family's saga she weaves the story of the legendary JPL- examining the complexities of its cultural history, from its start in 1936 to the triumphant Mars landings in 2004. She illuminates its founder, Frank Malina, whose brilliance in rocketry was shadowed by a flirtation with communism, driving him from the country even as we welcomed Wernher von Braun and his Nazi colleagues. Lord's own love of science fiction becomes a lens through which she views a profound cultural shift in the male-dominated world of space. And in pursuing the cause of her father's absence she stumbles on a hidden guilt, understanding "the anguish his proud silence caused both him and me, and how rooted that silence was in the culture of engineering."As in her acclaimed book Forever Barbie, which demystified an icon of feminine culture, Lord brings her penetrating insight to bear on a bastion of American masculinity, opening our eyes in unexpected and memorable ways.

    This stirring book reveals how scientific discovery has altered our perception of who we are and where we stand, and challenges us to weigh what we will do with that knowledge. Photos, many in color.

    Colorful characters, near misses, and the thrill of standing — or floating — in history's footprints make for a highly entertaining look at the fascinating history and glittering bounty beneath the waves. Included are accounts of Pearl Harbor, the Titanic, and Bikini Atoll, site of the world's first nuclear tests.
