How did the table fork acquire a fourth tine?  What advantage does the Phillips-head screw have over its single-grooved predecessor? Why does the paper clip look the way it does? What makes Scotch tape Scotch?   In this delightful book Henry Petroski takes a microscopic look at artifacts that most of us count on but rarely contemplate, including such icons of the everyday as pins, Post-its, and fast-food "clamshell" containers.  At the same time, he offers a convincing new theory of technological innovation as a response to the perceived failures of existing products—suggesting that irritation, and not necessity, is the mother of invention.

    From politics to the media, from education to the arts, liberals seem to be completely in control. It's no wonder, then, that so many prominent conservative traditionalists are hopelessly pessimistic about the future of Western Civilization. But what if this is just one side of the equation? What if it turns out that brewing beneath the surface, a renewed Christian age is rising? In this thought-provoking book, Dr. Steve Turley argues that there is in fact two revolutions concurrently taking place: a demographic revolution and a political revolution, both of which suggest a significant conservative Christian resurgence. HERE’S A PREVIEW OF WHAT YOU’LL LEARN ………. Why scholars believe that the fertility discrepancy between conservative Christians and secularists means a far more conservative future How Europe is already reversing its demographic decline with a nationalist baby boom How conservative Christianity is on the rise in the US Why scholars believe there is a resurgence of Christianity in Europe How these demographic and religious trends are already reshaping much of European society And much, much more! Drawing from scholarly studies and current events, Dr. Turley's study will inspire you to reject the naysayers predicting the twilight of the West, and instead embrace a hopeful vision of cultural renewal and the coming Christian majority.

     After a period as a fighter pilot in World War Two and then some time at university studying aeronautical engineering Crossfield joined NASA’s predecessor, the National Advisory Committee for Aeronautics. He quickly showed his talents as a research pilot and before long was training in a variety of aircraft, including the X-1, X-4, X-5, XF-92, D-558-I and D-558-II. Yet, Crossfield’s greatest flight came on November 20, 1953, when he was towed to a height of 72,000 feet by a Boeing P2B Superfortress before diving 62,000 feet and reaching a speed of 1,320 miles per hour. This meant that he was the first person in history to travel at more than twice the speed of sound. A number of years later Crossfield became both a test pilot and design consultant for the X-15 rocket-powered plane. Always Another Dawn provides brilliant insight into the development of this plane, and Crossfield’s impact upon it, which would eventually travel at six times the speed of sound. "Scott Crossfield was a pioneer and a legend in the world of test flight and space flight," said Mike Coats, Johnson Space Center Director. This book is essential reading for anyone interested in the development of aviation after the Second World War as well as the how men like Crossfield risked their lives the early years of the space race in order to further our attempts to reach the stars. Albert Scott Crossfield was an American naval officer and test pilot. He was instrumental in the development aeronautics and space flight through the 1950s. He co-authored Always Another Dawn, a story of a rocket test pilot, with Clay Blair Jr., which was published in 1960. He died in a place crash in 2006. Clay Blair Jr. had passed away in 1998.

    Barely 14 years old, her family was butchered before her eyes and she witnessed the deaths of two other women captives before her release by Chief Inkpaduta. Gardner suffered years of illness after her return to white culture but eventually made a successful and prosperous life with a family. This book went through seven editions in her lifetime and she eventually purchased the cabin and property from which she was abducted and turned them into a tourist attraction. The cabin still stands today near Spirit Lake, Iowa. Told from the view of a woman looking back three decades to her traumatic experience, Gardner used notes she had written down in the intervening years as well as public documents to produce a highly-readable and compelling narrative. For the first time, this long out-of-print volume is available as an affordable, well-formatted book for e-readers and smartphones.

    Coated in red dust, the terrain is bewilderingly empty. And yet multiple spacecraft are circling Mars, sweeping over Terra Sabaea, Syrtis Major, the dunes of Elysium, and Mare Sirenum—on the brink, perhaps, of a staggering find, one that would inspire humankind as much as any discovery in the history of modern science.In this beautifully observed, deeply personal book, Georgetown scientist Sarah Stewart Johnson tells the story of how she and other researchers have scoured Mars for signs of life, transforming the planet from a distant point of light into a world of its own.Johnson’s fascination with Mars began as a child in Kentucky, turning over rocks with her father and looking at planets in the night sky. She now conducts fieldwork in some of Earth’s most hostile environments, such as the Dry Valleys of Antarctica and the salt flats of Western Australia, developing methods for detecting life on other worlds. Here, with poetic precision, she interlaces her own personal journey—as a female scientist and a mother—with tales of other seekers, from Percival Lowell, who was convinced that a utopian society existed on Mars, to Audouin Dollfus, who tried to carry out astronomical observations from a stratospheric balloon. In the process, she shows how the story of Mars is also a story about Earth: This other world has been our mirror, our foil, a telltale reflection of our own anxieties and yearnings.Empathetic and evocative, The Sirens of Mars offers an unlikely natural history of a place where no human has ever set foot, while providing a vivid portrait of our quest to defy our isolation in the cosmos.

    Who thought up paper money? What was the secret element that made the Gutenberg printing press possible? And what is the connection between The Da Vinci Code and the collapse of Lehman Brothers? Fifty Inventions That Shaped the Modern Economy paints an epic picture of change in an intimate way by telling the stories of the tools, people, and ideas that had far-reaching consequences for all of us. From the plough to artificial intelligence, from Gillette’s disposable razor to IKEA’s Billy bookcase, bestselling author and Financial Times columnist Tim Harford recounts each invention’s own curious, surprising, and memorable story. Invention by invention, Harford reflects on how we got here and where we might go next. He lays bare often unexpected connections: how the bar code undermined family corner stores, and why the gramophone widened inequality. In the process, he introduces characters who developed some of these inventions, profited from them, and were ruined by them, as he traces the principles that helped explain their transformative effects. The result is a wise and witty book of history, economics, and biography.

    Fifty years ago, a few Americans became the first to do the reverse--and shared with Earth-bound audiences the view of their own planet hanging in the sky instead.Recently, the connection has been discovered to be even closer: a fragment of the Earth's surface was found embedded in a rock brought back from the Moon. And astronauts are preparing to return to the surface of the Moon after a half-century hiatus--this time to the dark side.Oliver Morton explores how the ways we have looked at the Moon have shaped our perceptions of the Earth: from the controversies of early astronomers such as van Eyck and Galileo, to the Cold War space race, to the potential use of the Moon as a stepping stone for further space exploration.Advanced technologies, new ambitions, and old dreams mean that men, women, and robots now seem certain to return to the Moon. For some, it is a future on which humankind has turned its back for too long. For others, an adventure yet to begin.

    Britain has always been a land of gallows, and every town had its hanging post and local 'turn off man.' First these men were criminals doing the work to save their own necks, and then later they were specialists in the trade of judicial killing. From the late Victorian period, the public hangman became a professional, and in the twentieth century the mechanics of hanging were streamlined as the executioners became adept at their craft. Britain's Most Notorious Hangmen tells the stories of the men who worked with their deadly skills at Tyburn tree or at the scaffolds in the prison yards across the country. Most were steeled to do the work by drink, and many suffered deeply from their despised profession. Here the reader will find the tale of the real Jack Ketch, the cases of neck-stretchers from the drunks like Curry and Askern, to the local workers of the ropes, Throttler Smith and the celebrated Billington and Pierrepoint dynasty. Along with some of the stories of famous killers such as William Palmer and James Bloomfield Rush, here are the bunglings, failures and desperate lives of the notorious hangmen, some who could entertain the vast crowds enjoying the show, and others who always faced the task as a terrible ordeal.

    T-Minus: The Race to the Moon is the story of the people who made it happen, both in the rockets and behind the scenes.

    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.

    Michener tackles the most ambitious subject of his career: space, the last great frontier. This astounding novel brings to life the dreams and daring of countless men and women—people like Stanley Mott, the engineer whose irrepressible drive for knowledge places him at the center of the American exploration effort; Norman Grant, the war hero and U.S. senator who takes his personal battle not only to a nation, but to the heavens; Dieter Kolff, Hitler’s rocket scientist, whose specialty is a rare commodity in this new era; Randy Claggett, the astronaut who meets his destiny on a mission to the far side of the moon; and Cynthia Rhee, the reporter whose determined crusade brings their story to a breathless world.

    In doing so, the authors synthesize information from astronomy, biology, and paleontology, and apply it to what we know about the rise of life on Earth and to what could possibly happen elsewhere in the universe. Everyone who has been thrilled by the recent discoveries of extrasolar planets and the indications of life on Mars and the Jovian moon Europa will be fascinated by Rare Earth, and its implications for those who look to the heavens for companionship.
