The calls to ban it were more or less instant.Re:cyclists is the tale of what happened next, of how we have spent two centuries wheeling our way about town and country on bikes--or on two-wheeled things that vaguely resembled what we now call bikes. Michael Hutchinson picks his way through those 200 years, discovering how cycling became a kinky vaudeville act for Parisians, how it became an American business empire, and how it went on to find a unique home in the British Isles. He considers the penny-farthing riders exploring the abandoned and lonely coaching roads during the railway era, and the Victorian high-society cyclists of the 1890s bicycle craze--a time when no aristocratic house party was without bicycles and when the Prince of Wales used to give himself an illicit thrill on a weekday afternoon by watching the women's riding-school in the Royal Albert Hall.Re:cyclists looks at how cycling became the sport, the pastime and the social life of millions of ordinary people, how it grew and how it suffered through the 1960s and '70s, and how at the dawn of the twenty-first century it rose again, much changed but still ultimately just someone careering along on two wheels.

    It is a one-ton robot with two brains, seventeen cameras, six wheels, nuclear power, and a laser beam on its head. No one human understands how all of its systems and instruments work. This essential reference to the Curiosity mission explains the engineering behind every system on the rover, from its rocket-powered jetpack to its radioisotope thermoelectric generator to its fiendishly complex sample handling system. Its lavishly illustrated text explains how all the instruments work -- its cameras, spectrometers, sample-cooking oven, and weather station -- and describes the instruments' abilities and limitations. It tells you how the systems have functioned on Mars, and how scientists and engineers have worked around problems developed on a faraway planet: holey wheels and broken focus lasers. And it explains the grueling mission operations schedule that keeps the rover working day in and day out.

    A tale of exploration, conquest, money, politics, and medicine, Panama Fever charts the challenges that marked the long, labyrinthine road to the building of the canal. Drawing on a wealth of new materials and sources, Matthew Parker brings to life the men who recognized the impact a canal would have on global politics and economics, and adds new depth to the familiar story of Teddy Roosevelt's remarkable triumph in making the waterway a reality.As thousands of workers succumbed to dysentery, yellow fever, and malaria, scientists raced to stop the deadly epidemics so that work could continue. The treatments they developed changed the course of medical history. The opening of the Panama Canal in 1914 spelled the end of the Victorian Age and the beginning of the "American Century." Panama Fever brilliantly captures the innovative thinking and backbreaking labor, as well as the commercial and political interests, that helped make America a global power.

    Unseen but listening intently was an audience of more than a billion people.It was Christmas Eve, 1968. And the astronauts of Apollo 8 -- Commander Frank Borman, Jim Lovell, and Bill Anders -- were participants in a mission that took them farther (500,000 miles) and faster (24,000 miles an hour) than any human had ever traveled. Of the 27 previous manned launches, none had ever ventured higher than 850 miles in altitude. Apollo 8 was the first manned vehicle to leave the earth's orbit and the first craft to orbit the moon.Confined within a tiny 11 x 13-foot capsule -- the size of the interior of a 15-passenger van -- the astronauts were aided in their journey by a computer less powerful than one of today's least sophisticated handheld calculators. The mission was not only a triumph of engineering, but also an enduring moment in history. It was a triumph for America and its space agency, and assured the public's continued interest in exploring space.

    His career spanned the entire Gemini and Apollo programs, from being the first person to spacewalk all the way around our world to the moment when he left man's last footprint on the Moon as commander of Apollo 17.Between those two historic events lay more adventures than an ordinary person could imagine as Cernan repeatedly put his life, his family and everything he held dear on the altar of an obsessive desire. Written with New York Times bestselling author Don Davis, The Last Man on the Moon is the astronaut story never before told - about the fear, love and sacrifice demanded of the few men who dared to reach beyond the heavens for the biggest prize of all - the Moon.

    The selections range from his earliest days as a theoretical physicist to his death in 1955; from such subjects as relativity, nuclear war or peace, and religion and science, to human rights, economics, and government.

    Indeed texting is so widespread that many parents, teachers, and media pundits have been outspoken in their criticism of it. Does texting spell the end of western civilization? In this humorous, level-headed and insightful book, David Crystal argues that the panic over texting is misplaced. Crystal, a world renowned linguist and prolific author on the uses and abuses of English, here looks at every aspect of the phenomenon of text-messaging and considers its effects on literacy, language, and society. He explains how texting began, how it works, who uses it, and how much it is used, and he shows how to interpret the mixture of pictograms, logograms, abbreviations, symbols, and wordplay typically used in texting. He finds that the texting system of conveying sounds and concepts goes back a long way--to the very origins of writing. And far from hindering children's literacy, texting turns out to help it.Illustrated with original art by Ed MacLachlan, a popular cartoonist whose work has appeared in Punch, Private Eye, New Statesman, and many other publications, Txting: The Gr8 Db8 is entertaining and instructive--reassuring for worried parents and teachers, illuminating for teenagers, and fascinating for everyone interested in what's currently happening to language and communication.

    Kennedy astonished the world on May 25, 1961, when he announced to Congress that the United States should land a man on the Moon by 1970. No group was more surprised than the scientists and engineers at NASA, who suddenly had less than a decade to invent space travel. When Kennedy announced that goal, no one knew how to navigate to the Moon. No one knew how to build a rocket big enough to reach the Moon, or how to build a computer small enough (and powerful enough) to fly a spaceship there. No one knew what the surface of the Moon was like, or what astronauts could eat as they flew there. On the day of Kennedy’s historic speech, America had a total of fifteen minutes of spaceflight experience—with just five of those minutes outside the atmosphere. Russian dogs had more time in space than U.S. astronauts. Over the next decade, more than 400,000 scientists, engineers, and factory workers would send 24 astronauts to the Moon. Each hour of space flight would require one million hours of work back on Earth to get America to the Moon on July 20, 1969. More than fifty years later, One Giant Leap is the sweeping, definitive behind-the-scenes account of the furious race to complete one of mankind’s greatest achievements. It’s a story filled with surprises—from the item the astronauts almost forgot to take with them (the American flag), to the extraordinary impact Apollo would have back on Earth, and on the way we live today. Charles Fishman introduces readers to the men and women who had to solve 10,000 problems before astronauts could reach the Moon. From the research labs of MIT, where the eccentric and legendary pioneer Charles Draper created the tools to fly the Apollo spaceships, to the factories where dozens of women sewed spacesuits, parachutes, and even computer hardware by hand, Fishman captures the exceptional feats of these ordinary Americans. One Giant Leap is the captivating story of men and women charged with changing the world as we knew it—their leaders, their triumphs, their near disasters, all of which led to arguably the greatest success story, and the greatest adventure story, of the twentieth century.

    Examines the effects of rapid industrial and technological changes upon the individual, the family, and society.

    Soon Gen Xers will be the only cohort of Americans who remember life as it was lived before the arrival of the Internet. They are, as Hennessey dubs them, “the last adult generation,” the sole remaining link to a time when childhood was still a bit dangerous but produced adults who were naturally resilient. More than a decade into the social media revolution, the American public is waking up to the idea that the tech sector’s intentions might not be as pure as advertised. The mountains of money being made off our browsing habits and purchase histories are used to fund ever-more extravagant and utopian projects that, by their very natures, will corrode the foundations of free society, leaving us all helpless and digitally enslaved to an elite crew of ultra-sophisticated tech geniuses. But it’s not too late to turn the tide. There’s still time for Gen X to write its own future. A spirited defense of free speech, eye contact, and the virtues of patience, Zero Hour for Gen X is a cultural history of the last 35 years, an analysis of the current social and historical moment, and a generational call to arms.

    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?

    A Slip of the Keyboard brings together for the first time the finest examples of Pratchett's non fiction writing, both serious and surreal: from musings on mushrooms to what it means to be a writer (and why banana daiquiris are so important); from memories of Granny Pratchett to speculation about Gandalf's love life, and passionate defences of the causes dear to him.With all the humour and humanity that have made his novels so enduringly popular, this collection brings Pratchett out from behind the scenes of the Discworld to speak for himself - man and boy, bibliophile and computer geek, champion of hats, orang-utans and Dignity in Dying.

    Less than 20 years after its founding, it boasts the largest constellation of commercial satellites in orbit, has pioneered reusable rockets, and in 2020 became the first private company to launch human beings into orbit. Half a century after the space race it is private companies, led by SpaceX, standing alongside NASA pushing forward into the cosmos, and laying the foundation for our exploration of other worlds.But before it became one of the most powerful players in the aerospace industry, SpaceX was a fledgling startup, scrambling to develop a single workable rocket before the money ran dry. The engineering challenge was immense; numerous other private companies had failed similar attempts. And even if SpaceX succeeded, they would then have to compete for government contracts with titans such as Lockheed Martin and Boeing, who had tens of thousands of employees and tens of billions of dollars in annual revenue. SpaceX had fewer than 200 employees and the relative pittance of $100 million in the bank.In Liftoff, Eric Berger, senior space editor at Ars Technica, takes readers inside the wild early days that made SpaceX. Focusing on the company’s first four launches of the Falcon 1 rocket, he charts the bumpy journey from scrappy underdog to aerospace pioneer. We travel from company headquarters in El Segundo, to the isolated Texas ranchland where they performed engine tests, to Kwajalein, the tiny atoll in the Pacific where SpaceX launched the Falcon 1. Berger has reported on SpaceX for more than a decade, enjoying unparalleled journalistic access to the company’s inner workings. Liftoff is the culmination of these efforts, drawing upon exclusive interviews with dozens of former and current engineers, designers, mechanics, and executives, including Elon Musk. The enigmatic Musk, who founded the company with the dream of one day settling Mars, is the fuel that propels the book, with his daring vision for the future of space.Filled with never-before-told stories of SpaceX’s turbulent beginning, Liftoff is a saga of cosmic proportions.
