Pegasus Bridge was the first engagement of D-Day, the turning point of World War II.This gripping account of it by acclaimed author Stephen Ambrose brings to life a daring mission so crucial that, had it been unsuccessful, the entire Normandy invasion might have failed. Ambrose traces each step of the preparations over many months to the minute-by-minute excitement of the hand-to-hand confrontations on the bridge. This is a story of heroism and cowardice, kindness and brutality—the stuff of all great adventures.

    Prized as “the best stone in Britain” by Roman invaders who carved jewelry out of it, coal has transformed societies, expanded frontiers, and sparked social movements, and still powers our electric grid. Yet coal’s world-changing power has come at a tremendous price, including centuries of blackening our skies and lungs—and now the dangerous warming of our global climate. Ranging from the “great stinking fogs” of London to the rat-infested coal mines of Pennsylvania, from the impoverished slums of Manchester to the toxic streets of Beijing, Coal is a captivating narrative about an ordinary substance with an extraordinary impact on human civilization.

    To mark the event, National Geographic magazine commissioned seven articles that explore the fascinating issues—including demographics, food security, climate change, fertility trends, managing biodiversity—surrounding this topic, which are collected for the first time in this special ebook.   Envi­ronment editor Robert Kunzig starts by sketching out a natural history of population. The issues associated with population growth seem endless: poverty, food and water supply, world health, climate change, deforestation, fertility rates, and more. In additional chapters Elizabeth Kolbert explores a new era—the “Anthropocene,” or the age of man—defined by our massive impact on the planet, which will endure long after our cities have crumbled; and takes us to the Mediterranean, where she delves into issues associated with increasing ocean acidification. In Bangladesh, Don Belt explores how the people of this crowded region can teach us about adapting to rising sea levels. In “Food Ark” we travel deep within the earth and around the globe to explore the seed banks that are preserving the variety of food species we may need to increase food production on an increasingly crowded planet. In Brazil, Cynthia Gournay explores the phenomenon of “Machisma” and shows how a mix of female empowerment and steamy soap operas helped bring down Brazil’s fertility rate and stoke its vibrant economy. Additionally we explore threats to biodiversity, and the return of cities—which may be the solution to many of our population woes. Join National Geographic on this incredible journey to explore our rapidly growing planet.

    This is the story of how these two men - separated in age by forty years - discovered the existence of the electromagnetic field and devised a radically new theory which overturned the strictly mechanical view of the world that had prevailed since Newton's time.The authors, veteran science writers with special expertise in physics and engineering, have created a lively narrative that interweaves rich biographical detail from each man's life with clear explanations of their scientific accomplishments. Faraday was an autodidact, who overcame class prejudice and a lack of mathematical training to become renowned for his acute powers of experimental observation, technological skills, and prodigious scientific imagination. James Clerk Maxwell was highly regarded as one of the most brilliant mathematical physicists of the age. He made an enormous number of advances in his own right. But when he translated Faraday's ideas into mathematical language, thus creating field theory, this unified framework of electricity, magnetism and light became the basis for much of later, 20th-century physics.Faraday's and Maxwell's collaborative efforts gave rise to many of the technological innovations we take for granted today - from electric power generation to television, and much more. Told with panache, warmth, and clarity, this captivating story of their greatest work - in which each played an equal part - and their inspiring lives will bring new appreciation to these giants of science.

    The Lockheed SR-71 Blackbird spy plane flew more than three-and-a-half times the speed of sound--so fast that no other aircraft could catch it. Above 80,000 feet, its pilots had to wear full-pressure flight suits similar to what was used aboard the space shuttle.Developed by the renowned Lockheed Skunk Works, the SR-71 was an awesome aircraft in every respect. It was withdrawn from use in 1998, when it was superseded by satellite technology. Twelve of the thirty-two aircraft were destroyed in accidents, but none were ever lost to enemy action.Throughout its thirty-four-year career, the SR-71 was the world's fastest and highest-flying operational manned aircraft. It set world records for altitude and speed: an absolute altitude record of 85,069 feet and an absolute speed record of 2,193.2 miles per hour.The Complete Book of the SR-71 Blackbird covers every aspect of the SR-71's development, manufacture, modification, and active service from the insider's perspective of one of its pilots and is lavishly illustrated with more than 400 photos. Former pilot and author Richard Graham also examines each of the fifty planes that came out the SR-71 program (fifteen A-12s; three YF-12s; and thirty-two SR-71s) and tells each plane's history, its unique specifications, and where each currently resides.

     The world's population is exploding, wild species are vanishing, our environment is degrading, and the costs of resources from oil to water are going nowhere but up. So what kind of world are we leaving for our children and grandchildren? Geoscientist and Guggenheim fellow Laurence Smith draws on the latest global modeling research to construct a sweeping thought experiment on what our world will be like in 2050. The result is both good news and bad: Eight nations of the Arctic Rim (including the United States) will become increasingly prosperous, powerful, and politically stable, while those closer to the equator will face water shortages, aging populations, and crowded megacities sapped by the rising costs of energy and coastal flooding.The World in 2050 combines the lessons of geography and history with state-of-the-art model projections and analytical data-everything from climate dynamics and resource stocks to age distributions and economic growth projections. But Smith offers more than a compendium of statistics and studies- he spent fifteen months traveling the Arctic Rim, collecting stories and insights that resonate throughout the book. It is an approach much like Jared Diamond took in Guns, Germs, and Steel and Collapse, a work of geoscientific investigation rich in the appreciation of human diversity. Packed with stunning photographs, original maps, and informative tables, this is the most authoritative, balanced, and compelling account available of the world of challenges and opportunities that we will leave for our children.

    Isolated and desolate, they were largely overlooked by early explorers until Charles Darwin arrived there in the 1830s. It was Darwin who recognized that Galapagos' isolation and desolation were advantages: the paucity of species and lack of outside influences made the workings of natural selection crystal clear. Since then, every important advance and controversy in evolutionary thinking has had its reflection on the Galapagos. In every sense-intellectually, institutionally, and culturally-the history of science on these islands is a history of the way evolutionary science was done for the past 150 years. Evolution's Workshop tells the story of Darwin's explorations there; the fabulous Gilded Age expeditions, run from rich men's gigantic yachts, that featured rough-and-ready science during the day and black-tie dinners every night; the struggle for control of research on the Galapagos; the current efforts by "creation scientists" to use the Galapagos to undercut evolutionary teaching; and many other compelling stories.

    Why, then, do their designs diverge so sharply? Humans, for instance, love right angles, while nature's angles are rarely right and usually rounded. Our technology goes around on wheels—and on rotating pulleys, gears, shafts, and cams—yet in nature only the tiny propellers of bacteria spin as true wheels. Our hinges turn because hard parts slide around each other, whereas nature's hinges (a rabbit's ear, for example) more often swing by bending flexible materials. In this marvelously surprising, witty book, Steven Vogel compares these two mechanical worlds, introduces the reader to his field of biomechanics, and explains how the nexus of physical law, size, and convenience of construction determine the designs of both people and nature. "This elegant comparison of human and biological technology will forever change the way you look at each."—Michael LaBarbera, American Scientist

    It's about states, armies and corporations. It's about orders from on high. Even history "from below" is often about trade unions and workers' parties. But what if that's simply because hierarchical institutions create the archives that historians rely on? What if we are missing the informal, less well documented social networks that are the true sources of power and drivers of change?The 21st century has been hailed as the Age of Networks. However, in The Square and the Tower, Niall Ferguson argues that networks have always been with us, from the structure of the brain to the food chain, from the family tree to freemasonry. Throughout history, hierarchies housed in high towers have claimed to rule, but often real power has resided in the networks in the town square below. For it is networks that tend to innovate. And it is through networks that revolutionary ideas can contagiously spread. Just because conspiracy theorists like to fantasize about such networks doesn't mean they are not real.From the cults of ancient Rome to the dynasties of the Renaissance, from the founding fathers to Facebook, The Square and the Tower tells the story of the rise, fall and rise of networks, and shows how network theory--concepts such as clustering, degrees of separation, weak ties, contagions and phase transitions--can transform our understanding of both the past and the present.Just as The Ascent of Money put Wall Street into historical perspective, so The Square and the Tower does the same for Silicon Valley. And it offers a bold prediction about which hierarchies will withstand this latest wave of network disruption--and which will be toppled.

    Each project uses color-coded pieces and is photographed from multiple angles, making it easy to see how the models are assembled without the need for step-by-step instructions. Every model illustrates a different principle, concept, or mechanism that will inspire your own original creations. You're encouraged to use these elements as building blocks to create your own masterpieces.The Technic models in Simple Machines demonstrate basic configurations of gears, shafts, pulleys, turntables, connectors, and the like. You'll learn how to create small, elegant machines like cranes, operable doors, motorized cars, a rubber band-powered rocket launcher, a hand-cranked drag racer, and even musical instruments.This visual guide, the first in the three-volume LEGO Technic Idea Book series, is the brainchild of master builder Yoshihito Isogawa of Tokyo, Japan. Each title is filled with photos of Isogawa's unique models, all of which are designed to fire the imaginations of LEGO builders young and old.Imagine. Create. Invent. Now, what will you build?NOTE: The LEGO Technic Idea Book series uses parts from various Technic sets. If you don't have some of the pieces shown in a particular model, experiment by substituting your own parts or visit the No Starch Press website for a list of the special parts used in the book.

    But how did the descendants of small primates manage to walk upright, become top predators, and populate the world? How were humans able to develop civilizations and produce a globalized economy? Now, in The Age of Wood, Roland Ennos shows for the first time that the key to our success has been our relationship with wood. “A lively history of biology, mechanics, and culture that stretches back 60 million years” (Nature) The Age of Wood reinterprets human history and shows how our ability to exploit wood’s unique properties has profoundly shaped our bodies and minds, societies, and lives. Ennos takes us on a sweeping journey from Southeast Asia and West Africa where great apes swing among the trees, build nests, and fashion tools; to East Africa where hunter gatherers collected their food; to the structural design of wooden temples in China and Japan; and to Northern England, where archaeologists trace how coal enabled humans to build an industrial world. Addressing the effects of industrialization—including the use of fossil fuels and other energy-intensive materials to replace timber—The Age of Wood not only shows the essential role that trees play in the history and evolution of human existence, but also argues that for the benefit of our planet we must return to more traditional ways of growing, using, and understanding trees. A brilliant blend of recent research and existing scientific knowledge, this is an “excellent, thorough history in an age of our increasingly fraught relationships with natural resources” (Kirkus Reviews, starred review).

    From menacing moonshiners and armed bandits to charging elephants and man-eating tigers, Merlin Tuttle has stopped at nothing to find and protect bats on every continent they inhabit. Enamored of bats ever since discovering a colony in a cave as a boy, Tuttle saw how effective photography could be in persuading people not to fear bats, and he has spent his career traveling the world to document them.Few people realize how sophisticated and intelligent bats are. Tuttle shares research showing that frog-eating bats can identify frogs by their calls, that vampire bats have a social order similar to that of primates, and that bats have remarkable memories. Bats also provide enormous benefits by eating crop pests, pollinating plants, and carrying seeds needed for reforestation. They save farmers billions of dollars annually and are essential to a healthy planet.Sharing highlights from a lifetime of adventure and discovery, Tuttle takes us to the frontiers of bat research and conservation and forever changes the way we see these poorly understood yet fascinating creatures.

    

    It is our twenty-first century New World; its explorers robots, shipped 350 million miles from Earth to uncover the distant planet’s secrets.Its most recent scout is Curiosity—a one-ton, Jeep-sized nuclear-powered space laboratory—which is now roving the Martian surface to determine whether the red planet has ever been physically capable of supporting life. In Red Rover, geochemist Roger Wiens, the principal investigator for the ChemCam laser instrument on the rover and veteran of numerous robotic NASA missions, tells the unlikely story of his involvement in sending sophisticated hardware into space, culminating in the Curiosity rover's amazing journey to Mars.In so doing, Wiens paints the portrait of one of the most exciting scientific stories of our time: the new era of robotic space exploration. Starting with NASA’s introduction of the Discovery Program in 1992, scrappier, more nimble missions became the order of the day, as manned missions were confined to Earth orbit, and behemoth projects went extinct. This strategic shift presented huge scientific opportunities, but tight budgets meant that success depended more than ever on creative engineering and human ingenuity. Beginning with the Genesis mission that launched his career, Wiens describes the competitive, DIY spirit of these robotic enterprises, from conception to construction, from launch to heart-stopping crashes and smooth landings.An inspiring account of the real-life challenges of space exploration, Red Rover vividly narrates what goes into answering the question: is there life elsewhere in the universe?

    Decades ago, astronauts brought back 850 pounds of rocks from their lunar journeys; the U.S. gave some away as “goodwill” gifts to the world’s nations. Over time, many of them disappeared, stolen or lost in the aftermath of political turmoil, and offered for millions on the black market. Gutheinz, first as a NASA investigator and then the leader of a intrepid group of students, has dedicated his life to getting them back. Author Joe Kloc tells a wild story of geopolitics, crime, science, and one man’s obsession with keeping the moon out of the wrong hands.
