Lacking the ability to measure their longitude, sailors throughout the great ages of exploration had been literally lost at sea as soon as they lost sight of land. Thousands of lives, and the increasing fortunes of nations, hung on a resolution.The scientific establishment of Europe—from Galileo to Sir Issac Newton—had mapped the heavens in both hemispheres in its certain pursuit of a celestial answer. In stark contrast, one man, John Harrison, dared to imagine a mechanical solution—a clock that would keep precise time at sea, something no clock had ever been able to do on land. Longitude is a dramatic human story of an epic scientific quest and Harrison's forty-year obsession with building his perfect timekeeper, known today as the chronometer. Full of heroism and chicanery, it is also a fascinating brief history of astronomy, navigation, and clock-making, and opens a new window on our world.On its 10th anniversary, a gift edition of this classic book, with a forward by one of history's greatest explorers, and eight pages of color illustrations.

    While not every story is concerned with the hard science behind space travel and other futuristic ventures, fiction can give listeners an amazing insight into what people could be capable of and what people dream of doing.In the 10 lectures of The Science of Sci-Fi: From Warp Speed to Interstellar Travel, Professor Erin Macdonald interweaves real science and the achievements of the imagination to reveal the truth that underlies favorite stories and sheds light on what the future may hold. From faster-than-light travel to journeys through time itself, science fiction makes humanity seem limitless.

    From bone-whittling microgravity to eye-popping profits, the risks and rewards of space settlement have never been so close at hand.More than fifty years after the Apollo 11 moon landing, why is there so little human presence in space? Will we ever reach Mars? What will it take to become a multiplanet species, colonizing the solar system and traveling to other stars?Spacefarers meets these questions head on. While many books have speculated on the possibility of living beyond the Earth, few have delved into the practical challenges or plausible motives for leaving the safe confines of our home planet. Christopher Wanjek argues that there is little doubt we will be returning to the Moon and exploring Mars in the coming decades, given the potential scientific and commercial bonanza. Private industry is already taking a leading role and earning profits from human space activity. This can be, Wanjek suggests, a sustainable venture and a natural extension of earthbound science, business, and leisure. He envisions hotels in low-earth orbit and mining, tourism, and science on the Moon. He also proposes the slow, steady development of science bases on Mars, to be followed by settlements if Martian gravity will permit reproduction and healthy child development.An appetite for wonder will take us far, but if we really want to settle new worlds, we'll need the earnest plans of engineers, scientists, and entrepreneurs. Wanjek introduces us to those planners, who are striving right now to make life in space a reality.

    Kennedy’s inspiring challenge, and America’s race to the moon.“We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard; because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one we intend to win.”—President John F. KennedyOn May 25, 1961, JFK made an astonishing announcement: his goal of putting a man on the moon by the end of the decade. In this engrossing, fast-paced epic, Douglas Brinkley returns to the 1960s to recreate one of the most exciting and ambitious achievements in the history of humankind. American Moonshot brings together the extraordinary political, cultural, and scientific factors that fueled the birth and development of NASA and the Mercury, Gemini and Apollo projects, which shot the United States to victory in the space race against the Soviet Union at the height of the Cold War.Drawing on new primary source material and major interviews with many of the surviving figures who were key to America’s success, Brinkley brings this fascinating history to life as never before. American Moonshot is a portrait of the brilliant men and women who made this giant leap possible, the technology that enabled us to propel men beyond earth’s orbit to the moon and return them safely, and the geopolitical tensions that spurred Kennedy to commit himself fully to this audacious dream. Brinkley’s ensemble cast of New Frontier characters include rocketeer Wernher von Braun, astronaut John Glenn and space booster Lyndon Johnson.A vivid and enthralling chronicle of one of the most thrilling, hopeful, and turbulent eras in the nation’s history, American Moonshot is an homage to scientific ingenuity, human curiosity, and the boundless American spirit.

    There is something about cars that stirs up intense feelings in people - how it makes them look to the outside world, how it makes them feel about themselves, how it looks to their girlfriends or their mates, or their neighbours. These feelings are humorously described in May on Motors, as James takes us on the road and looks at the cars that have shaped him, his world and the ordinary people of Britain.In May on Motors, James has brought together his most controversial and amusing pieces to make a brilliant collection that will amuse and inspire all car enthusiasts.

    Who has not wondered about how the human body works? Can a person drink too much water? How does gravity make things fall? From topics as varied as the Earth and atoms to sports and music, we all carry with us those questions we've always wanted answered but never knew whom to ask.Mysteries lurk in our bodies, our houses, the outdoors, in the sky above us, and the universe beyond us. Now, award-winning high school science teacher Larry Scheckel tackles 250 questions that help us to more clearly understand all of these mysteries. Scheckel perfected the art of explaining science topics not only as a science teacher for more than 38 years in his native Wisconsin, but also through writing a weekly column in his local paper, the "Tomah Journal," in which each week he'd field a question like those that are collected in this book.

    The hunt for the Higgs was the subject of wide media attention due to the cost of the project, the complexity of the experiment, and the importance of its result. And, when it was announced with great fanfare in 2012 that physicists has succeeded in creating and identifying this all-important new particle, the discovery was celebrated around the world.And yet, virtually no one who read that news could tell you what, exactly, the Higgs boson was, and why its discovery was so important that we had to spend 10 billion dollars and build the single largest and most complex device in the history of mankind in order to find it. When you understand the details, this story ranks as one of the most thrilling in the history of modern science.Award-winning theoretical physicist Sean Carroll, a brilliant researcher as well as a gifted speaker who excels in explaining scientific concepts to the public, is perfectly positioned to tell this story. In this 12-lecture masterpiece of scientific reporting, you'll learn everything you need to know to fully grasp the significance of this discovery, including the basics of quantum mechanics; the four forces that comprise the Standard Model of particle physics; how these forces are transmitted by fields and particles; and the importance of symmetry in physics.You also get an in-depth view of the Large Hadron Collider - the largest machine ever built, and the device responsible for finally revealing the concept of the Higgs boson as reality. By the end, you'll understand how the Higgs boson verifies the final piece in the Standard Model of particle physics, and how its discovery validates and deepens our understanding of the universe.

    Starting once again with fossils, he turns his gaze skyward, showing us how the entirety of the universe’s fourteen-billion-year history can be seen in our bodies. As he moves from our very molecular composition (a result of stellar events at the origin of our solar system) through the workings of our eyes, Shubin makes clear how the evolution of the cosmos has profoundly marked our own bodies. Fully illustrated with black and white drawings.

    The general theory of relativity describes the behavior of very large things, and quantum theory the behavior of very small things. In this landmark book, John Gribbin—one of the best-known science writers of the past thirty years—presents his own version of the Holy Grail of physics, the search that has been going on for decades to find a unified “Theory of Everything” that combines these ideas into one mathematical package, a single equation that could be printed on a T-shirt, containing the answer to life, the Universe, and everything. With his inimitable mixture of science, history, and biography, Gribbin shows how—despite skepticism among many physicists—these two great theories are very compatible, and point to a deep truth about the nature of our existence. The answer lies, intriguingly, with the age of the universe: 13.8 billion years.

    S. Abbey was called “the Dark Lord,” “the Godfather,” and “UNO”—short for unidentified NASA official. He was said to be secretive, despotic, a Space Age Machiavelli. Yet Abbey had more influence on human spaceflight than almost anyone in history. His story has never been told—until now.   The Astronaut Maker takes readers inside NASA to learn the real story of how Abbey rose to power, from young pilot and wannabe astronaut to engineer, bureaucrat, and finally director of the Johnson Space Center. During a thirty-seven-year career, mostly out of the spotlight, he oversaw the selection of every astronaut class from 1978 to 1987, deciding who got to fly and when. He was with the Apollo 1 astronauts the night before the fatal fire in January 1967. He was in mission control the night of the Apollo 13 accident and organized the recovery effort. Abbey also led NASA’s recruitment of women and minorities as space shuttle astronauts and was responsible for hiring Sally Ride.    Written by Michael Cassutt, the coauthor of the acclaimed astronaut memoirs DEKE! and We Have Capture, and informed by countless hours of interviews with Abbey and his family, friends, adversaries, and former colleagues, The Astronaut Maker is the ultimate insider’s account of ambition and power politics at NASA.
