His breaking of the German U-boat Enigma cipher in World War II ensured Allied-American control of the Atlantic. But Turing's vision went far beyond the desperate wartime struggle. Already in the 1930s he had defined the concept of the universal machine, which underpins the computer revolution. In 1945 he was a pioneer of electronic computer design. But Turing's true goal was the scientific understanding of the mind, brought out in the drama and wit of the famous "Turing test" for machine intelligence and in his prophecy for the twenty-first century.Drawn in to the cockpit of world events and the forefront of technological innovation, Alan Turing was also an innocent and unpretentious gay man trying to live in a society that criminalized him. In 1952 he revealed his homosexuality and was forced to participate in a humiliating treatment program, and was ever after regarded as a security risk. His suicide in 1954 remains one of the many enigmas in an astonishing life story.

    To many people, she is still 'la reine méchante', whose extravagance and frivolity helped to bring down the French monarchy; her indifference to popular suffering epitomised by the (apocryphal) words: 'let them eat cake'. Others are equally passionate in her defence: to them, she is a victim of misogyny.Antonia Fraser examines her influence over the king, Louis XVI, the accusations and sexual slurs made against her, her patronage of the arts which enhanced French cultural life, her imprisonment, the death threats made against her, rumours of lesbian affairs, her trial (during which her young son was forced to testify to sexual abuse by his mother) and her eventual execution by guillotine in 1793.

    In the early eighteenth century, the Pirate Republic was home to some of the great pirate captains, including Blackbeard, "Black Sam" Bellamy, and Charles Vane. Along with their fellow pirates—former sailors, indentured servants, and runaway slaves—this "Flying Gang" established a crude but distinctive democracy in the Bahamas, carving out their own zone of freedom in which servants were free, blacks could be equal citizens, and leaders were chosen or deposed by a vote. They cut off trade routes, sacked slave ships, and severed Europe from its New World empires, and for a brief, glorious period the Republic was a success.

    Much as Brainiac offered a behind-the-scenes look at the little-known demimonde of competitive trivia buffs, Maphead finally gives equal time to that other downtrodden underclass: America's map nerds.In a world where geography only makes the headlines when college students are (endlessly) discovered to be bad at it, these hardy souls somehow thrive. Some crisscross the map working an endless geographic checklist: visiting all 3,143 U.S. counties, for example, or all 936 UNESCO World Heritage Sites. Some pore over million-dollar collections of the rarest maps of the past; others embrace the future by hunting real-world cartographic treasures like "geocaches" or "degree confluences" with GPS device in hand. Some even draw thousands of their own imaginary maps, lovingly detailing worlds that never were.Ken Jennings was a map nerd from a young age himself, you will not be surprised to learn, even sleeping with a bulky Hammond atlas at the side of his pillow, in lieu of the traditional Teddy bear. As he travels the nation meeting others of his tribe--map librarians, publishers, "roadgeeks," pint-sized National Geographic Bee prodigies, the computer geniuses behind Google Maps and other geo-technologies--he comes to admire these geographic obsessives. Now that technology and geographic illiteracy are increasingly insulating us from the lay of the land around us, we are going to be needing these people more than ever. Mapheads are the ones who always know exactly where they are--and where everything else is as well.

    But as engineer Gustave Eiffel built the now-famous landmark to be the spectacular centerpiece of the 1889 World's Fair, he stirred up a storm of vitriol from Parisian tastemakers, lawsuits, and predictions of certain structural calamity. In Eiffel's Tower, Jill Jonnes, critically acclaimed author of Conquering Gotham, presents a compelling account of the tower's creation and a superb portrait of Belle Epoque France. As Eiffel held court that summer atop his one-thousand-foot tower, a remarkable host of artists and personalities-Buffalo Bill, Annie Oakley, Gauguin, Whistler, and Edison-traveled to Paris and the Exposition Universelle to mingle and make their mark. Like The Devil in the White City, Brunelleschi's Dome, and David McCullough's accounts of the building of the Panama Canal and the Brooklyn Bridge, Eiffel's Tower combines technological and social history and biography to create a richly textured portrayal of an age of aspiration, dreams, and progress.

    Battered by year-round freezing rain and constant winds, it is one of the most inhospitable places on earth. To be shipwrecked there means almost certain death.Incredibly, at the same time on the opposite end of the island, another ship runs aground during a storm. Separated by only twenty miles and the island’s treacherous, impassable cliffs, the crews of the Grafton and the Invercauld face the same fate. And yet where the Invercauld’s crew turns inward on itself, fighting, starving, and even turning to cannibalism, Musgrave’s crew bands together to build a cabin and a forge—and eventually, to find a way to escape. Using the survivors’ journals and historical records, maritime historian Joan Druett brings to life this untold story about leadership and the fine line between order and chaos.

    But the so-called Dark Ages also gave us the first universities, eyeglasses, and mechanical clocks, proving that the Middle Ages were home to a vibrant scientific culture.In The Light Ages, Cambridge science historian Seb Falk takes us on an immersive tour of medieval science through the story of one fourteenth-century monk, John of Westwyk. From multiplying Roman numerals to navigating by the stars, curing disease, and telling time with an ancient astrolabe, we learn emerging science alongside Westwyk, while following the gripping story of the struggles and successes of an ordinary man in a precarious world. An enlightening history that argues that these times weren’t so dark after all, The Light Ages shows how medieval ideas continue to color how we see the world today.

    A riveting account of three heroic astronauts who took one of the most dangerous space flights ever, from the New York Times bestselling author of Shadow Divers. In early 1968, the Apollo program was on shaky footing. President Kennedy's end-of-decade deadline to put a man on the Moon was in jeopardy, and the Soviets were threatening to pull ahead in the space race. By August 1968, with its back against the wall, NASA decided to scrap its usual methodical approach and shoot for the heavens. With just four months to prepare--a fraction of the normal time--the agency would send the first men in history to the Moon. In a year of historic violence and discord--the Tet offensive, the assassinations of MLK and RFK, the Chicago DNC riots--the Apollo 8 mission was the boldest test of what America could do. With a focus on astronauts Frank Borman, Jim Lovell, and Bill Anders, and their wives and children, this is a vivid, gripping, you-are-there narrative that shows anew the epic danger involved, and the singular bravery it took, for man to leave Earth for the first time--and to arrive at a new world.

    Heading deep into uncharted Arctic waters, they carried the aspirations of a young country burning to be the first nation to reach the North Pole. Two years into the voyage, the Jeannette's hull was breached by an impassable stretch of pack ice, forcing the crew to abandon ship amid torrents of rushing of water. Hours later, the ship had sunk below the surface, marooning the men a thousand miles north of Siberia, where they faced a terrifying march with minimal supplies across the endless ice pack.Enduring everything from snow blindness and polar bears to ferocious storms and labyrinths of ice, the crew battled madness and starvation as they struggled desperately to survive. With thrilling twists and turns, In The Kingdom of Ice is a tale of heroism and determination in the most brutal place on Earth.

    But to those who collect them, the map trade can be a cutthroat business, inhabited by quirky and sometimes disreputable characters in search of a finite number of extremely rare objects. Once considered a respectable antiquarian map dealer, E. Forbes Smiley spent years doubling as a map thief —until he was finally arrested slipping maps out of books in the Yale University library. The Map Thief delves into the untold history of this fascinating high-stakes criminal and the inside story of the industry that consumed him. Acclaimed reporter Michael Blanding has interviewed all the key players in this stranger-than-fiction story, and shares the fascinating histories of maps that charted the New World, and how they went from being practical instruments to quirky heirlooms to highly coveted objects. Though pieces of the map theft story have been written before, Blanding is the first reporter to explore the story in full—and had the rare privilege of having access to Smiley himself after he’d gone silent in the wake of his crimes. Moreover, although Smiley swears he has admitted to all of the maps he stole, libraries claim he stole hundreds more—and offer intriguing clues to prove it. Now, through a series of exclusive interviews with Smiley and other key individuals, Blanding teases out an astonishing tale of destruction and redemption. The Map Thief interweaves Smiley’s escapades with the stories of the explorers and mapmakers he knew better than anyone. Tracking a series of thefts as brazen as the art heists in Provenance and a subculture as obsessive as the oenophiles in The Billionaire’s Vinegar, Blanding has pieced together an unforgettable story of high-stakes crime.

    Hardy, in the years before World War I. Through their eyes the reader is taken on a journey through numbers theory. Ramanujan would regularly telescope 12 steps of logic into two - the effect is said to be like Dr Watson in the train of some argument by Sherlock Holmes. The language of symbols and infinitely large (and small) regions of mathematics should be rendered with clarity for the general reader.

    David Livingstone? The New York Times bestselling coauthor of Survivor: The Ultimate Game investigates in this thrilling account.With the utterance of a single line--"Doctor Livingstone, I presume?"--a remote meeting in the heart of Africa was transformed into one of the most famous encounters in exploration history. But the true story behind Dr. David Livingstone and journalist Henry Morton Stanley is one that has escaped telling. Into Africa is an extraordinarily researched account of a thrilling adventure--defined by alarming foolishness, intense courage, and raw human achievement.In the mid-1860s, exploration had reached a plateau. The seas and continents had been mapped, the globe circumnavigated. Yet one vexing puzzle remained unsolved: what was the source of the mighty Nile river? Aiming to settle the mystery once and for all, Great Britain called upon its legendary explorer, Dr. David Livingstone, who had spent years in Africa as a missionary. In March 1866, Livingstone steered a massive expedition into the heart of Africa. In his path lay nearly impenetrable, uncharted terrain, hostile cannibals, and deadly predators. Within weeks, the explorer had vanished without a trace. Years passed with no word.While debate raged in England over whether Livingstone could be found--or rescued--from a place as daunting as Africa, James Gordon Bennett, Jr., the brash American newspaper tycoon, hatched a plan to capitalize on the world's fascination with the missing legend. He would send a young journalist, Henry Morton Stanley, into Africa to search for Livingstone. A drifter with great ambition, but little success to show for it, Stanley undertook his assignment with gusto, filing reports that would one day captivate readers and dominate the front page of the New York Herald.Tracing the amazing journeys of Livingstone and Stanley in alternating chapters, author Martin Dugard captures with breathtaking immediacy the perils and challenges these men faced. Woven into the narrative, Dugard tells an equally compelling story of the remarkable transformation that occurred over the course of nine years, as Stanley rose in power and prominence and Livingstone found himself alone and in mortal danger. The first book to draw on modern research and to explore the combination of adventure, politics, and larger-than-life personalities involved, Into Africa is a riveting read.

    Acclaimed historian G. J. Meyer reveals the flesh-and-bone reality in all its wild excess.In 1485, young Henry Tudor, whose claim to the throne was so weak as to be almost laughable, crossed the English Channel from France at the head of a ragtag little army and took the crown from the family that had ruled England for almost four hundred years. Half a century later his son, Henry VIII, desperate to rid himself of his first wife in order to marry a second, launched a reign of terror aimed at taking powers no previous monarch had even dreamed of possessing. In the process he plunged his kingdom into generations of division and disorder, creating a legacy of blood and betrayal that would blight the lives of his children and the destiny of his country.The boy king Edward VI, a fervent believer in reforming the English church, died before bringing to fruition his dream of a second English Reformation. Mary I, the disgraced daughter of Catherine of Aragon, tried and failed to reestablish the Catholic Church and produce an heir.
