That evidence, he argues, shows that 700 million years ago the Earth did indeed freeze over completely, becoming a giant “snowball,” in the worst climatic catastrophe in history. Even more startling is his assertion that, instead of ending life on Earth, this global deep freeze was the trigger for the Cambrian Explosion, the hitherto unexplained moment in geological time when a glorious profusion of complex life forms first emerged from the primordial ooze.In a story full of intellectual intrigue, we follow the irascible but brilliant Hoffman and a supporting cast of intrepid geologists as they scour the planet, uncovering clue after surprising clue. We travel to a primeval lagoon at Shark Bay in western Australia, where dolphins cavort with swimmers every morning at seven and “living rocks” sprout out of the water like broccoli heads; to the desolate and forbidding ice fields of a tiny Arctic archipelago seven hundred miles north of Norway; to the surprising fossil beds that decorate Newfoundland’s foggy and windswept coastline; and on to the superheated salt pans of California’s Death Valley.Through the contours of these rich and varied landscapes Walker teaches us to read the traces of geological time with expert eyes, and we marvel at the stunning feats of resilience and renewal our remarkable planet is capable of. Snowball Earth is science writing at its most gripping and enlightening.

    He is separated from his family as they are swept up in the government’s mass deportation of Armenians into internment camps. Gradually realizing the unthinkable—that they are all being driven to their deaths—he fights, through starvation and thirst, not to lose hope. Just before killing squads slaughter his caravan during a forced desert march, Stepan manages to escape, making a perilous six-day trek to the Euphrates River carrying nothing more than two cups of water and one gold coin. In his desperate bid for survival, Stepan dons disguises, outmaneuvers gendarmes, and, when he least expects it, encounters the miraculous kindness of strangers.The Hundred-Year Walk alternates between Stepan’s saga and another journey that takes place a century later, after his family discovers his long-lost journals. Reading this rare firsthand account, his granddaughter Dawn MacKeen finds herself first drawn into the colorful bazaars before the war and then into the horrors Stepan later endured. Inspired to retrace his steps, she sets out alone to Turkey and Syria, shadowing her resourceful, resilient grandfather across a landscape still rife with tension. With his journals guiding her, she grows ever closer to the man she barely knew as a child. Their shared story is a testament to family, to home, and to the power of the human spirit to transcend the barriers of religion, ethnicity, and even time itself.

    But ask what it means, and the result will be a brawl. For a century, most physicists have followed Niels Bohr's Copenhagen interpretation and dismissed questions about the reality underlying quantum physics as meaningless. A mishmash of solipsism and poor reasoning, Copenhagen endured, as Bohr's students vigorously protected his legacy, and the physics community favored practical experiments over philosophical arguments. As a result, questioning the status quo long meant professional ruin. And yet, from the 1920s to today, physicists like John Bell, David Bohm, and Hugh Everett persisted in seeking the true meaning of quantum mechanics. What Is Real? is the gripping story of this battle of ideas and of the courageous scientists who dared to stand up for truth.

    Now Terry Tempest Williams, the author of the environmental classic Refuge and the beloved memoir When Women Were Birds, returns with The Hour of Land, a literary celebration of our national parks, an exploration of what they mean to us and what we mean to them.From the Grand Tetons in Wyoming to Acadia in Maine to Big Bend in Texas and more, Williams creates a series of lyrical portraits that illuminate the unique grandeur of each place while delving into what it means to shape a landscape with its own evolutionary history into something of our own making. Part memoir, part natural history, and part social critique, The Hour of Land is a meditation and a manifesto on why wild lands matter to the soul of America.

    The expedition was described by the two men in Sea of Cortez, published in 1941. The day-to-day story of the trip is told here in the Log, which combines science, philosophy and high-spirited adventure.Log from the Sea of Cortez includes the narrative of the journey and the essay “About Ed Ricketts.” It does not include pictures and detailed descriptions of the species collected by Steinbeck and Ricketts. (See also Sea of Cortez.)

    Turnbull lived among the Mbuti people for three years as an observer, not a researcher, so he offers a charming and intimate firsthand account of the people and their culture, and especially the individuals and their personalities. The Forest People is a timeless work of academic and humanitarian significance, sure to delight readers as they take a trip into a foreign culture and learn to appreciate the joys of life through the eyes of the Mbuti people.

    It was to last five years and transform him from an amiable and somewhat aimless young man into a scientific celebrity. Even more vitally, it was to set in motion the intellectual currents that culminated in the arrival of The Origin of Species in Victorian drawing-rooms in 1859. His journal, reprinted here in a shortened version, is vivid and immediate, showing us a naturalist making patient observations, above all in geology. As well as a profusion of natural history detail, it records many other things that caught Darwin’s eye, from civil war in Argentina to the new colonial settlements of Australia. The editors have provided an excellent introduction and notes for this Penguin Classics edition, which also contains maps and appendices, including an essay on scientific geology and the Bible by Robert FitzRoy, Darwin’s friend and captain of the Beagle.

    Testing themselves against treacherous currents, braving depths that induced hallucinatory effects, navigating through wreckage as perilous as a minefield, they pushed themselves to their limits and beyond, brushing against death more than once in the rusting hulks of sunken ships.But in the fall of 1991, not even these courageous divers were prepared for what they found 230 feet below the surface, in the frigid Atlantic waters sixty miles off the coast of New Jersey: a World War II German U-boat, its ruined interior a macabre wasteland of twisted metal, tangled wires, and human bones–all buried under decades of accumulated sediment.No identifying marks were visible on the submarine or the few artifacts brought to the surface. No historian, expert, or government had a clue as to which U-boat the men had found. In fact, the official records all agreed that there simply could not be a sunken U-boat and crew at that location.Over the next six years, an elite team of divers embarked on a quest to solve the mystery. Some of them would not live to see its end. Chatterton and Kohler, at first bitter rivals, would be drawn into a friendship that deepened to an almost mystical sense of brotherhood with each other and with the drowned U-boat sailors–former enemies of their country. As the men’s marriages frayed under the pressure of a shared obsession, their dives grew more daring, and each realized that he was hunting more than the identities of a lost U-boat and its nameless crew.Author Robert Kurson’s account of this quest is at once thrilling and emotionally complex, and it is written with a vivid sense of what divers actually experience when they meet the dangers of the ocean’s underworld. The story of Shadow Divers often seems too amazing to be true, but it all happened, two hundred thirty feet down, in the deep blue sea.

    Thoreau lived alone in a secluded cabin at Walden Pond. It is one of the most influential and compelling books in American literature. This new paperback edition-introduced by noted American writer John Updike-celebrates the 150th anniversary of this classic work. Much of Walden's material is derived from Thoreau's journals and contains such engaging pieces as "Reading" and "The Pond in the Winter" Other famous sections involve Thoreau's visits with a Canadian woodcutter and with an Irish family, a trip to Concord, and a description of his bean field. This is the complete and authoritative text of Walden-as close to Thoreau's original intention as all available evidence allows. For the student and for the general reader, this is the ideal presentation of Thoreau's great document of social criticism and dissent.

    She chaperoned baby sea turtles on their journey to sea. She pursued bad guys on her galloping patrol horse. She jumped into rescue helicopters bound for the heart of the Grand Canyon. She won arguments with bears. She slept with a few too many rattlesnakes. Hell yeah, it was the best job in the world! Fortunately, Andrea survived it. In this graphic and yet surprisingly funny account of her and others’ extraordinary careers, Lankford unveils a world in which park rangers struggle to maintain their idealism in the face of death, disillusionment, and the loss of a comrade killed while holding that thin green line between protecting the park from the people, the people from the park, and the people from each other. Ranger Confidential is the story behind the scenery of the nation’s crown jewels—Yosemite, Grand Canyon, Yellowstone, Great Smokies, Denali. In these iconic landscapes, where nature and humanity constantly collide, scenery can be as cruel as it is redemptive.

    For 20 years, an outspoken New York writer and a rather more restrained London bookseller carried on an increasingly touching correspondence. In her first letter to Marks & Co., Helene Hanff encloses a wish list, but warns, "The phrase 'antiquarian booksellers' scares me somewhat, as I equate 'antique' with expensive." Twenty days later, on October 25, 1949, a correspondent identified only as FPD let Hanff know that works by Hazlitt and Robert Louis Stevenson would be coming under separate cover. When they arrive, Hanff is ecstatic--but unsure she'll ever conquer "bilingual arithmetic." By early December 1949, Hanff is suddenly worried that the six-pound ham she's sent off to augment British rations will arrive in a kosher office. But only when FPD turns out to have an actual name, Frank Doel, does the real fun begin. Two years later, Hanff is outraged that Marks & Co. has dared to send an abridged Pepys diary. "i enclose two limp singles, i will make do with this thing till you find me a real Pepys. THEN i will rip up this ersatz book, page by page, AND WRAP THINGS IN IT." Nonetheless, her postscript asks whether they want fresh or powdered eggs for Christmas. Soon they're sharing news of Frank's family and Hanff's career.

     What drives a man to travel to sixty countries and spend a fortune to count birds? And what if that man is your father? Richard Koeppel's obsession began at the age of eleven, in Queens, New York, when he first spotted a Brown Thrasher and promptly jotted the sighting in a notebook. Several decades, one failed marriage, and two sons later, he added an astonishing 517 birds to that list on a single trip to Kenya. Soon after, he ended the last romantic relationship he would ever have, scaled down his medical practice, and decided to see every bird on earth, becoming a "Big Lister," a member of a subculture of competitive bird-watchers worldwide, all pursuing the same goal. Over twenty-five years, he collected more than 7,000 species (of a known 9,600), becoming one of about ten people ever to do so. "To See Every Bird on Earth" explores the thrill of this chase, the all-absorbing crusade at the expense of all else, and travel, to places both dangerous and dull, for the sake of making a check mark in a notebook. It's also the story of obsession-answering the questions why list? and why birds?-and how it defines us. A riveting glimpse into a fascinating subculture, To See Every Bird on Earth traces the love, loss, and reconnection between a father and a son, and explains why birds are so critical to the human search for our place in the world.

    Fate landed her at a wildlife sanctuary on the edge of the Amazon jungle where she was assigned to a beautiful and complex puma named Wayra. Wide-eyed, inexperienced, and comically terrified, Laura made the scrappy, make-do camp her home. And in Wayra, she made a friend for life.They weren’t alone, not with over a hundred quirky animals to care for, each lost and hurt in its own way: a pair of suicidal, bra-stealing monkeys, a frustrated parrot desperate to fly, and a pig with a wicked sense of humor. The humans, too, were cause for laughter and tears. There were animal whisperers, committed staff, wildly devoted volunteers, handsome heartbreakers, and a machete-wielding prom queen who carried Laura through. Most of all, there were the jungle—lyrical and alive—and Wayra, who would ultimately teach Laura so much about love, healing, and the person she was capable of becoming.Set against a turbulent and poignant backdrop of deforestation, the illegal pet trade, and forest fires, The Puma Years explores what happens when two desperate creatures in need of rescue find one another.

    Each year they are seen by millions of visitors, and they have become as integral a part of the Tower as its ancient stones. But their role is even more important than that—legend has it that if the ravens should ever leave, the Tower will crumble into dust and great harm will befall the kingdom.The responsibility for ensuring that such a disaster never comes to pass falls to one man: the Ravenmaster. The current holder of the position is Yeoman Warder Christopher Skaife, and in this fascinating, entertaining and touching book he memorably describes the ravens’ formidable intelligence, their idiosyncrasies and their occasionally wicked sense of humour. The Ravenmaster is a compelling, inspiring and irreverent story that will delight and surprise anyone with an interest in British history or animal behaviour.

    Twenty years after the genocide that left Rwanda in ruins, Giller Prize-winning author Will Ferguson travels deep into the once-mysterious "Land of a Thousand Hills" with his friend and cohort Jean-Claude Munyezamu, a man who escaped Rwanda just months before the killings began.      From the legendary source of the Nile to Dian Fossey's famed "gorillas in the mist," from innovative refugee camps along the Congolese border to the world's most escapable prison, from tragic genocide sites to open savannahs and a bridge to freedom, from schoolyard soccer pitches to a cunning plan to get rich on passion fruit, Ferguson and Munyezamu discover a country reborn.     Funny, engaging, poignant, and at times heartbreaking, Road Trip Rwanda is the lively tale of two friends, the open road, and the hidden heart of a continent.
