For real.If you're like most people, geometry is a sterile and dimly remembered exercise you gladly left behind in the dust of ninth grade, along with your braces and active romantic interest in pop singers. If you recall any of it, it's plodding through a series of miniscule steps only to prove some fact about triangles that was obvious to you in the first place. That's not geometry. Okay, it is geometry, but only a tiny part, which has as much to do with geometry in all its flush modern richness as conjugating a verb has to do with a great novel.Shape reveals the geometry underneath some of the most important scientific, political, and philosophical problems we face. Geometry asks: Where are things? Which things are near each other? How can you get from one thing to another thing? Those are important questions. The word "geometry," from the Greek for "measuring the world." If anything, that's an undersell. Geometry doesn't just measure the world—it explains it. Shape shows us how.

    Here are astounding animals of every stripe: Dung beetles that steer by the light of the Milky Way. Ants and bees that rely on patterns of light invisible to humans. Sea turtles and moths that find their way using Earth’s magnetic field. Humpback whales that swim thousands of miles while holding a rocksteady course. Birds that can locate their nests on a tiny island after crisscrossing an ocean.The age of viewing animals as unthinking drones is over. As Supernavigators makes clear, a stunning array of species command senses and skills—and arguably, types of intelligence—beyond our own. Weaving together interviews with leading animal behaviorists and the groundbreaking discoveries of Nobel Prize–winning scientists, David Barrie reveals these wonders in a whole new light.

    Now in it's tenth edition, this text makes chemistry exciting to students by showing them why important concepts are relevant to their lives and future careers.

    Thanks largely to YouTube clips posted by the sloth orphanage in Costa Rica, sloths have attracted a vast audience of admirers. Instead of seeing them as ridiculous anachronisms of which we know little, they have turned into creatures considered by many to be the most endearing on earth.Over much the same period, scientific investigations have also changed our view of sloths. No longer are they seen as total misfits in the modern world but, in the words of one specialist sloth investigator, they are 'masters of an alternative lifestyle'.In this wonderfully entertaining celebration of this most unique of creatures, William Hartston reveals the fascinating history of the sloth, from the prehistoric ground sloth to modern pygmy sloths in Panama, explores the current state of the science of sloths and reveals the truth behind sloth behaviour.

    In the days that follow, a doctor performs miraculous surgery on Keeley, who wakes up to find that everything about his world has changed. He seems to sense things before they happen, and he thinks he’s capable of feats that are clearly impossible. It’s a strange and compelling new world for him, one he quickly realizes is also incredibly dangerous.Meanwhile at a $12 billion facility in hardscrabble North Texas, a super collider lies two hundred feet beneath the Earth’s surface. Leading a team of scientists, Mike McNair, a brilliant physicist, works to uncover one of the universe’s greatest secrets–a theoretical particle that binds the universe together, often called The God Particle. When his efforts are undermined by the man who has poured his own vast fortune into the project, McNair begins to suspect that something in his research has gone very, very wrong.Now, these two men are about to come together, battling mysteries of science and of the soul–and venturing to a realm beyond reason, beyond faith, perhaps even beyond life and death.

    And before there were fish in the sea, there were cephalopods - the ancestors of modern squid and Earth’s first truly substantial animals. Cephalopods became the first creatures to rise from the seafloor, essentially inventing the act of swimming. With dozens of tentacles and formidable shells, they presided over an undersea empire for millions of years. But when fish evolved jaws, the ocean’s former top predator became its most delicious snack. Cephalopods had to step up their game. Many species streamlined their shells and added defensive spines, but these enhancements only provided a brief advantage. Some cephalopods then abandoned the shell entirely, which opened the gates to a flood of evolutionary innovations: masterful camouflage, fin-supplemented jet propulsion, perhaps even dolphin-like intelligence. Squid Empire is an epic adventure spanning hundreds of millions of years, from the marine life of the primordial ocean to the calamari on tonight’s menu. Anyone who enjoys the undersea world—along with all those obsessed with things prehistoric—will be interested in the sometimes enormous, often bizarre creatures that ruled the seas long before the first dinosaurs.

    Wild species, too, are escaping warming seas and desiccated lands, creeping, swimming, and flying in a mass exodus from their past habitats. News media presents this scrambling of the planet's migration patterns as unprecedented, provoking fears of the spread of disease and conflict and waves of anxiety across the Western world. On both sides of the Atlantic, experts issue alarmed predictions of millions of invading aliens, unstoppable as an advancing tsunami, and countries respond by electing anti-immigration leaders who slam closed borders that were historically porous.But the science and history of migration in animals, plants, and humans tell a different story. Far from being a disruptive behavior to be quelled at any cost, migration is an ancient and lifesaving response to environmental change, a biological imperative as necessary as breathing. Climate changes triggered the first human migrations out of Africa. Falling sea levels allowed our passage across the Bering Sea. Unhampered by barbed wire, migration allowed our ancestors to people the planet, catapulting us into the highest reaches of the Himalayan mountains and the most remote islands of the Pacific, creating and disseminating the biological, cultural, and social diversity that ecosystems and societies depend upon. In other words, migration is not the crisis--it is the solution.Conclusively tracking the history of misinformation from the 18th century through today's anti-immigration policies, The Next Great Migration makes the case for a future in which migration is not a source of fear, but of hope.

    They live everywhere—deep inside caves, 18,000 feet high in the Himalayas, inside computers, in Yellowstone’s hot springs, and in the ears and nostrils of much larger creatures. There are insects that have ears on their knees, eyes on their penises, and tongues under their feet. Most of us think life would be better without bugs. In fact, life would be impossible without them. Most of us know that we would not have honey without honeybees, but without the pinhead-sized chocolate midge, cocoa flowers would not pollinate. No cocoa, no chocolate. The ink that was used to write the Declaration of Independence was derived from galls on oak trees, which are induced by a small wasp. The fruit fly was essential to medical and biological research experiments that resulted in six Nobel prizes. Blowfly larva can clean difficult wounds; flour beetle larva can digest plastic; several species of insects have been essential to the development of antibiotics. Insects turn dead plants and animals into soil. They pollinate flowers, including crops that we depend on. They provide food for other animals, such as birds and bats. They control organisms that are harmful to humans. Life as we know it depends on these small creatures. With ecologist Anne Sverdrup-Thygeson as our capable, entertaining guide into the insect world, we’ll learn that there is more variety among insects than we can even imagine and the more you learn about insects, the more fascinating they become. Buzz, Sting, Bite is an essential introduction to the little creatures that make the world go round.

    Americans eat more bananas than apples and oranges combined. In others parts of the world, bananas are what keep millions of people alive. But for all its ubiquity, the banana is surprisingly mysterious; nobody knows how bananas evolved or exactly where they originated. Rich cultural lore surrounds the fruit: In ancient translations of the Bible, the 'apple' consumed by Eve is actually a banana (it makes sense, doesn't it?). Entire Central American nations have been said to rise and fall over the banana. But the biggest mystery about the banana today is whether it will survive. A seedless fruit with a unique reproductive system, every banana is a genetic duplicate of the next, and therefore susceptible to the same blights. Today's yellow banana, the Cavendish, is increasingly threatened by such a blight -- and there's no cure in sight. Banana combines a pop-science journey around the globe, a fascinating tale of an iconic American business enterprise, and a look into the alternately tragic and hilarious banana subculture (one does exist) -- ultimately taking us to the high-tech labs where new bananas are literally being built in test tubes, in a race to save the world's most beloved fruit.

    So she put together a climbing kit: she sewed a harness from an old seat belt, gathered hundreds of feet of rope, and found a tool belt for her pencils and rulers. Up she went, into the trees. Forty years later, Lowman remains one of the world’s foremost arbornauts, known as the “real-life Lorax.” She planned one of the first treetop walkways and helps create more of these bridges through the eighth continent all over the world.With a voice as infectious in its enthusiasm as it is practical in its optimism, The Arbornaut chronicles Lowman’s irresistible story. From climbing solo hundreds of feet into the air in Australia’s rainforests to measuring tree growth in the northeastern United States, from searching the redwoods of the Pacific coast for new life to studying leaf eaters in Scotland’s Highlands, from conducting a BioBlitz in Malaysia to conservation planning in India and collaborating with priests to save Ethiopia’s last forests, Lowman launches us into the life and work of a field scientist, ecologist, and conservationist. She offers hope, specific plans, and recommendations for action; despite devastation across the world, through trees, we can still make an immediate and lasting impact against climate change.A blend of memoir and fieldwork account, The Arbornaut gives us the chance to live among scientists and travel the world—even in a hot-air balloon! It is the engrossing, uplifting story of a nerdy tree climber—the only girl at the science fair—who becomes a giant inspiration, a groundbreaking, ground-defying field biologist, and a hero for trees everywhere.Includes black-and-white illustrations

    In this thrill-ride across millennia and continents, the complete history of the planet comes to life: from the Earth's fiery birth to its near-obliteration in the Triassic period, and from the first signs of human life to the tentative future of a world with a burgeoning population and a global warming crisis. Covering a wide range of topics including astrophysics, zoology, and sociology, and complete with maps and illustrations, What on Earth Happened? In Brief is the endlessly entertaining story of the planet, life, and people.

    Indeed, most are only barely aware of the diseases caused by them, except, perhaps, for mad cow disease. Yet prions are the stuff of a revolutionary science?a science that might lead to cures for some of humankind?s most devastating diseases.Fatal Flaws is a scientific detective story about this elusive protein, starting with the discovery of kuru, a disease unique to New Guinea in the 1950s that baffled scientists and carried with it whispers of cannibalism. Kuru began a scientific stampede to seek out the agent of this mysterious disease?the prion?a misfolded protein whose existence some of the world?s top scientists still find difficult to accept. Today, the subject of prions remains controversial, yet the proteins might promise new treatments for some of the most intractable brain diseases, ones that affect millions around the planet, including Parkinson?s, ALS and Alzheimer?s.In Fatal Flaws, Jay Ingram unties a complicated interweaving of biology, medicine, human tragedy, surprise and disbelief in the world of prions, and he unravels some of history?s most stunning revelations about disease, the brain and infection.

    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.

    It is the time of the gloaming, the owl-light. Out in the wood, the resident tawny has started calling, Hoo-hoo-hoo-h-o-o-o.’ There is something about owls. They feature in every major culture from the Stone Age onwards. They are creatures of the night, and thus of magic. They are the birds of ill-tidings, the avian messengers from the Other Side. But owls – with the sapient flatness of their faces, their big, round eyes, their paternal expressions – are also reassuringly familiar. We see them as wise, like Athena’s owl, and loyal, like Harry Potter's Hedwig. Human-like, in other words. No other species has so captivated us. In The Secret Life of the Owl, John Lewis-Stempel explores the legends and history of the owl. And in vivid, lyrical prose, he celebrates all the realities of this magnificent creature, whose natural powers are as fantastic as any myth.'John Lewis-Stempel is one of the best nature writers of his generation' Country Life
