The lens he invented was a brilliant feat of engineering that made lighthouses blaze many times brighter, farther, and more efficiently. Battling the establishment, his own poor health, and the limited technology of the time, Fresnel was able to achieve his goal of illuminating the entire French coast. At first, the British sought to outdo the new Fresnel-equipped lighthouses as a matter of national pride. Americans, too, resisted abandoning their primitive lamps, but the superiority of the Fresnel lens could not be denied for long. Soon, from Dunkirk to Saigon, shores were brightened with it.  The Fresnel legacy played an important role in geopolitical events, including the American Civil War. No sooner were Fresnel lenses finally installed along U.S. shores than they were drafted: the Union blockaded the Confederate coast; the Confederacy set about thwarting it by dismantling and hiding or destroying the powerful new lights.Levitt’s scientific and historical account, rich in anecdote and personality, brings to life the fascinating untold story of Augustin Fresnel and his powerful invention.

    Wise, rhapsodic, exalted – Island Home is not just a brilliant, moving insight into the life and art of one of our finest writers, but a compelling investigation into the way our country shapes us.

    Dozens died of radiation poisoning, fallout contaminated half the continent, and thousands fell ill.In Chernobyl, Serhii Plokhy draws on new sources to tell the dramatic stories of the firefighters, scientists, and soldiers who heroically extinguished the nuclear inferno. He lays bare the flaws of the Soviet nuclear industry, tracing the disaster to the authoritarian character of the Communist party rule, the regime's control over scientific information, and its emphasis on economic development over all else.Today, the risk of another Chernobyl looms in the mismanagement of nuclear power in the developing world. A moving and definitive account, Chernobyl is also an urgent call to action.

    Detroit: A Biography takes a long, unflinching look at the evolution of one of America's great cities, and one of the nation's greatest urban failures. This authoritative yet accessible narrative seeks to explain how the city grew to become the heart of American industry and how its utter collapse from nearly two million residents in 1950 to less than 715,000 some six decades later resulted from a confluence of public policies, private industry decisions, and deeply ingrained racism. Drawing from U.S. Census data and including profiles of individuals who embody the recent struggles and hopes of the city, this book chronicles the evolution of what a modern city once was and what it has become.

    From the thawing tundra linking a Yup'ik village in Alaska to its hunter-gatherer past to the shifting sand dunes revealing the impressively preserved homes of neolithic farmers in Scotland, Jamie explores how the changing natural world can alter our sense of time. Most movingly, she considers, as her father dies and her children leave home, the surfacing of an older, less tethered sense of herself. In precise, luminous prose, Surfacing offers a profound sense of time passing and an antidote to all that is instant, ephemeral, unrooted.

    In Fatal Journey, acclaimed historian and biographer Peter C. Mancall narrates Hudson's final expedition.In the winter of 1610, after navigating dangerous fields of icebergs near the northern tip of Labrador, Hudson's small ship became trapped in winter ice. Provisions grew scarce and tensions mounted amongst the crew. Within months, the men mutinied, forcing Hudson, his teenage son, and seven other men into a skiff, which they left floating in the Hudson Bay.A story of exploration, desperation, and icebound tragedy, Fatal Journey vividly chronicles the undoing of the great explorer, not by an angry ocean, but at the hands of his own men.

    Set in Edwardian London and on the stormy coasts of Cornwall, Cape Cod, and Nova Scotia, Thunderstruck evokes the dynamism of those years when great shipping companies competed to build the biggest, fastest ocean liners, scientific advances dazzled the public with visions of a world transformed, and the rich outdid one another with ostentatious displays of wealth. Against this background, Marconi races against incredible odds and relentless skepticism to perfect his invention: the wireless, a prime catalyst for the emergence of the world we know today. Meanwhile, Crippen, “the kindest of men,” nearly commits the perfect crime. With his superb narrative skills, Erik Larson guides these parallel narratives toward a relentlessly suspenseful meeting on the waters of the North Atlantic. Along the way, he tells of a sad and tragic love affair that was described on the front pages of newspapers around the world, a chief inspector who found himself strangely sympathetic to the killer and his lover, and a driven and compelling inventor who transformed the way we communicate. Thunderstruck presents a vibrant portrait of an era of séances, science, and fog, inhabited by inventors, magicians, and Scotland Yard detectives, all presided over by the amiable and fun-loving Edward VII as the world slid inevitably toward the first great war of the twentieth century. Gripping from the first page, and rich with fascinating detail about the time, the people, and the new inventions that connect and divide us, Thunderstruck is splendid narrative history from a master of the form.

    In 2016, the acclaimed memoirist Brian Castner retraced Mackenzie's route by canoe in a grueling journey -- and discovered the Passage he could not find.Disappointment River is a dual historical narrative and travel memoir that at once transports readers back to the heroic age of North American exploration and places them in a still rugged but increasingly fragile Arctic wilderness in the process of profound alteration by the dual forces of globalization and climate change. Fourteen years before Lewis and Clark, Mackenzie set off to cross the continent of North America with a team of voyageurs and Chipewyan guides, to find a trade route to the riches of the East. What he found was a river that he named "Disappointment." Mackenzie died thinking he had failed. He was wrong.In this book, Brian Castner not only retells the story of Mackenzie's epic voyages in vivid prose, he personally retraces his travels, battling exhaustion, exposure, mosquitoes, white water rapids and the threat of bears. He transports readers to a world rarely glimpsed in the media, of tar sands, thawing permafrost, remote indigenous villages and, at the end, a wide open Arctic Ocean that could become a far-northern Mississippi of barges and pipelines and oil money.

    In a series of ten vibrant urban biographies that stretch from the shores of Puritan Boston to Dublin, Hong Kong, New Delhi, Liverpool, and beyond, acclaimed historian Tristram Hunt demonstrates that urbanism is in fact the most lasting of Britain's imperial legacies.Combining historical scholarship, cultural criticism, and personal reportage, Hunt offers a new history of empire, excavated from architecture and infrastructure, from housing and hospitals, sewers and statues, prisons and palaces. Avoiding the binary verdict of empire as "good" or "bad," he traces the collaboration of cultures and traditions that produced these influential urban centers, the work of an army of administrators, officers, entrepreneurs, slaves, and renegades. In these ten cities, Hunt shows, we also see the changing faces of British colonial settlement: a haven for religious dissenters, a lucrative slave-trading post, a center of global hegemony.Lively, authoritative, and eye-opening, Cities of Empire makes a crucial new contribution to the history of colonialism.

    Deliberately hiding from the outside world, they are the unconquered, the last survivors of an ancient culture that predates the arrival of Columbus in the New World.  In this gripping first-person account of adventure and survival, author Scott Wallace chronicles an expedition into the Amazon’s uncharted depths, discovering the rainforest’s secrets while moving ever closer to a possible encounter with one such tribe—the mysterious flecheiros, or “People of the Arrow,” seldom-glimpsed warriors known to repulse all intruders with showers of deadly arrows. On assignment for National Geographic, Wallace joins Brazilian explorer Sydney Possuelo at the head of a thirty-four-man team that ventures deep into the unknown in search of the tribe. Possuelo’s mission is to protect the Arrow People. But the information he needs to do so can only be gleaned by entering a world of permanent twilight beneath the forest canopy.Danger lurks at every step as the expedition seeks out the Arrow People even while trying to avoid them. Along the way, Wallace uncovers clues as to who the Arrow People might be, how they have managed to endure as one of the last unconquered tribes, and why so much about them must remain shrouded in mystery if they are to survive. Laced with lessons from anthropology and the Amazon’s own convulsed history, and boasting a Conradian cast of unforgettable characters—all driven by a passion to preserve the wild, but also wracked by fear, suspicion, and the desperate need to make it home alive—The Unconquered reveals this critical battleground in the fight to save the planet as it has rarely been seen, wrapped in a page-turning tale of adventure.

    But while the nature of memory is a constant, the nature of history has changed radically over the past forty years, for good but also for ill. In The Purpose of the Past, historian Gordon S. Wood examines the sea change in the field through considerations of some of its most important historians and their works. His book serves as both a history of American history-neither wholly a celebration nor a critique-and an argument for its ongoing necessity. These are both the best of times and the worst of times for American history. New currents of thought have brought refreshing and vitally necessary changes to the discipline, expanding its compass to include previously underexamined and undervalued groups and subjects. At the same time, however, strains of extreme, even nihilistic, relativism have assaulted the relevance, even the legitimacy, of the historian's work. The divide between the work of academic and popular historians has widened into a chasm, separating some of the field's most important new ideas from what would give them much greater impact: any kind of real audience. But The Purpose of the Past is not another crotchety elegy for what history once was but sadly now isn't; it is also a celebration of what, at its best, it is, and a powerful argument for its ongoing necessity. Along the way The Purpose of the Past offers wonderful insight into what great historians do, and how they can stumble, and what strains of thought have dominated the marketplace of ideas in historical scholarship. A master historian's commanding assessment of his field, The Purpose of the Past will enlarge the capacity to appreciate history of anyone who reads it

    How they got here, persevered, and ultimately thrived is a story that resonates from the Pleistocene to our modern era. The lower sea levels of the Ice Age exposed a vast land bridge between Asia and North America, but the land bridge was not the only way across. Different people arrived from different directions, and not all at the same time.The first explorers of the New World were few, their encampments fleeting. The continent they reached had no people but was inhabited by megafauna--mastodons, giant bears, mammoths, saber-toothed cats, five-hundred-pound panthers, enormous bison, and sloths that stood one story tall. The first people were hunters--Paleolithic spear points are still encrusted with the proteins of their prey--but they were wildly outnumbered and many would themselves have been prey to the much larger animals.Atlas of a Lost World chronicles the last millennia of the Ice Age, the violent oscillations and retreat of glaciers, the clues and traces that document the first encounters of early humans, and the animals whose presence governed the humans' chances for survival. A blend of science and personal narrative reveals how much has changed since the time of mammoth hunters, and how little. Across unexplored landscapes yet to be peopled, readers will see the Ice Age, and their own age, in a whole new light.

    He had long been given up for lost, and rumors quickly circulated about where he had been on his three-year round-the-world voyage, and about the plunder he had brought home to fill Queen Elizabeth's treasury. However, a veil of secrecy was immediately imposed on the expedition: Drake's journals and charts were impounded, and his men were forbidden, on pain of death, to divulge where they had been—especially during the summer of 1579, when they had dropped from sight in the North Pacific.In hindsight, Drake's journey was arguably the greatest sea voyage of all time. In a ship barely one hundred feet long, he sailed more than 40,000 miles, much of the voyage at extraordinary speed; disrupted the Spanish Empire in the New World; encountered often hostile native peoples on four continents; narrowly escaped disaster on numerous occasions; and became the first captain to circumnavigate the globe.Samuel Bawlf masterfully recounts the drama of this extraordinary expedition within the context of England's struggle to withstand the aggression of Catholic Europe and Drake's ambition for English enterprise in the Pacific. He offers fascinating insight into life at sea in the sixteenth century—from the dangers of mutiny and the lack of knowledge about wind and current to the arduous physical challenges faced every day by Drake's men. But it is Bawlf's assertion of Drake's whereabouts in the summer of 1579 that gives his book even greater originality. From a seminal study of maps of the period, Bawlf shows with certainty that Drake sailed all the way to Alaska—much farther than anyone has heretofore imagined—thereby rewriting the history of exploration. Drake was, Bawlf claims, in search of the western entrance to the fabled Northwest Passage, at which he planned to found England's first colony, which could wrest control of the Pacific, and the wealth of the East Indies, from Spain. Drake's voyage was, in fact, far ahead of its time: another 200 years would pass before the eighteenth-century explorers of record reached the northwest coast of North America.A cast of luminous characters runs through The Secret Voyage of Sir Francis Drake: Philip II of Spain, Europe's most powerful monarch; Elizabeth's spymaster and powerful advisor, Francis Walsingham; the encyclopedic cosmographer John Dee; and Abraham Ortelius, the great Dutch mapmaker to whom Drake leaked his Pacific discoveries. In the end, though, it is Francis Drake himself who comes most fully to life through the lens of his epic voyage. Remembered most as a privateer and for his victory over the Spanish Armada, the Drake that emerges from these pages is so much more: a dynamic leader of men, a brilliant navigator and sailor, and surely one of history's most daring explorers.

    The most famous work by the Australian novelist and poet, For the Term of His Natural Life is a powerful tale of an Australian penal settlement, which originally appeared in serial form in a Melbourne paper.
