Breaking down the symbols themselves, they pose a series of questions: What is energy? What is mass? What has the speed of light got to do with energy and mass? In answering these questions, they take us to the site of one of the largest scientific experiments ever conducted. Lying beneath the city of Geneva, straddling the Franco-Swiss boarder, is a 27 km particle accelerator, known as the Large Hadron Collider. Using this gigantic machine—which can recreate conditions in the early Universe fractions of a second after the Big Bang—Cox and Forshaw will describe the current theory behind the origin of mass.Alongside questions of energy and mass, they will consider the third, and perhaps, most intriguing element of the equation: 'c' - or the speed of light. Why is it that the speed of light is the exchange rate? Answering this question is at the heart of the investigation as the authors demonstrate how, in order to truly understand why E=mc2, we first must understand why we must move forward in time and not backwards and how objects in our 3-dimensional world actually move in 4-dimensional space-time. In other words, how the very fabric of our world is constructed. A collaboration between two of the youngest professors in the UK, Why Does E=mc2? promises to be one of the most exciting and accessible explanations of the theory of relativity in recent years.

    Her long-term research has revealed much of what we now know about these complex and intelligent animals. Here she chronicles the lives of the members of the T families led by matriarchs Teresia, Slit Ear, Torn Ear, Tania, and Tuskless. With a new afterword catching up on the families and covering current conservation issues, Moss's story will continue to fascinate animal lovers."One is soon swept away by this 'Babar' for adults. By the end, one even begins to feel an aversion for people. One wants to curse human civilization and cry out, 'Now God stand up for the elephants!'"—Christopher Lehmann-Haupt, New York Times"Moss speaks to the general reader, with charm as well as scientific authority. . . . [An] elegantly written and ingeniously structured account." —Raymond Sokolov, Wall Street Journal"Moss tells the story in a style so conversational . . . that I felt like a privileged visitor riding beside her in her rickety Land-Rover as she showed me around the park." —Sarah Blaffer Hrdy, New York Times Book Review"A prose-poem celebrating a species from which we could learn some moral as well as zoological lessons." —Chicago Tribune

    Memory is not their guide — no one butterfly makes the round trip — but each year somehow find their way to the same fifty acres of forest on the high slopes of Mexico’s Neovolcanic Mountains, and then make the return trip in the spring.In Four Wings and a Prayer, Sue Halpern sets off on an adventure to delve into the secrets behind this extraordinary phenomenon. She visits scientists and butterfly lovers across the country, offering a keenly observed portrait of the monarchs’ migration and of the people for whom they have become a glorious obsession. Combining science, memoir, and travel writing, Four Wings and a Prayer is an absorbing travelogue and a fascinating meditation on a profound mystery of the natural world.

    Hurd's forays into the land of carnivorous plants, swamp gas, and bog men provide fertile ground for rich thoughts about mythology, literature, Eastern spirituality, and human longing. In her observations of these muddy environments, she finds ample metaphor for human creativity, imagination, and fear.

    See ISBN 9780465094646History is full of strange animal stories invented by the brightest and most influential, from Aristotle to Disney. But when it comes to understanding animals, we’ve got a long way to go.Whether we’re watching a viral video of romping baby pandas or looking at a picture of penguins ‘holding hands’, we often project our own values – innocence, abstinence, hard work – onto animals. So you’ve probably never considered that moose get drunk and that penguins are notorious cheats.In The Unexpected Truth About Animals Zoologist Lucy unravels many such myths – that eels are born from sand, that swallows hibernate under water, and that bears gave birth to formless lumps that are licked into shape by their mothers – to show that the stories we create reveal as much about us as they do about the animals.Astonishing, illuminating and laugh-out-loud funny.

    Yet this enigmatic animal is more complex than the legends that surround it. With a shrinking wilderness and global warming, the future of the wolverine is uncertain. The Wolverine Way reveals the natural history of this species and the forces that threaten its future, engagingly told by Douglas Chadwick, who volunteered with the Glacier Wolverine Project. This five-year study in Glacier National Park – which involved dealing with blizzards, grizzlies, sheer mountain walls, and other daily challenges to survival – uncovered key missing information about the wolverine’s habitat, social structure and reproduction habits. Wolverines, according to Chadwick, are the land equivalent of polar bears in regard to the impacts of global warming. The plight of wolverines adds to the call for wildlife corridors that connect existing habitat that is proposed by the Freedom to Roam coalition.

    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.)

    The tiger isn’t just killing people, it’s annihilating them, and a team of men and their dogs must hunt it on foot through the forest in the brutal cold. As the trackers sift through the gruesome remains of the victims, they discover that these attacks aren’t random: the tiger is apparently engaged in a vendetta. Injured, starving, and extremely dangerous, the tiger must be found before it strikes again.As he re-creates these extraordinary events, John Vaillant gives us an unforgettable portrait of this spectacularly beautiful and mysterious region. We meet the native tribes who for centuries have worshipped and lived alongside tigers, even sharing their kills with them. We witness the arrival of Russian settlers in the nineteenth and early twentieth centuries, soldiers and hunters who greatly diminished the tiger populations. And we come to know their descendants, who, crushed by poverty, have turned to poaching and further upset the natural balance of the region.This ancient, tenuous relationship between man and predator is at the very heart of this remarkable book. Throughout we encounter surprising theories of how humans and tigers may have evolved to coexist, how we may have developed as scavengers rather than hunters, and how early Homo sapiens may have fit seamlessly into the tiger’s ecosystem. Above all, we come to understand the endangered Siberian tiger, a highly intelligent super-predator that can grow to ten feet long, weigh more than six hundred pounds, and range daily over vast territories of forest and mountain.Beautifully written and deeply informative, The Tiger circles around three main characters: Vladimir Markov, a poacher killed by the tiger; Yuri Trush, the lead tracker; and the tiger himself. It is an absolutely gripping tale of man and nature that leads inexorably to a final showdown in a clearing deep in the taiga.

    In the great halls of science, dogma holds that Darwin's theory of natural selection explains every branch on the tree of life: which species thrive, which wither away to extinction, and what features each evolves. But can adaptation by natural selection really account for everything we see in nature? Yale University ornithologist Richard Prum--reviving Darwin's own views--thinks not. Deep in tropical jungles around the world are birds with a dizzying array of appearances and mating displays: Club-winged Manakins who sing with their wings, Great Argus Pheasants who dazzle prospective mates with a four-foot-wide cone of feathers covered in golden 3D spheres, Red-capped Manakins who moonwalk. In thirty years of fieldwork, Prum has seen numerous display traits that seem disconnected from, if not outright contrary to, selection for individual survival. To explain this, he dusts off Darwin's long-neglected theory of sexual selection in which the act of choosing a mate for purely aesthetic reasons--for the mere pleasure of it--is an independent engine of evolutionary change. Mate choice can drive ornamental traits from the constraints of adaptive evolution, allowing them to grow ever more elaborate. It also sets the stakes for sexual conflict, in which the sexual autonomy of the female evolves in response to male sexual control. Most crucially, this framework provides important insights into the evolution of human sexuality, particularly the ways in which female preferences have changed male bodies, and even maleness itself, through evolutionary time. The Evolution of Beauty presents a unique scientific vision for how nature's splendor contributes to a more complete understanding of evolution and of ourselves.

    In order to present this complicated subject in an accurate and entertaining way, he put in years of research. He sat in on anatomy classes, dissections, and even reached inside the rib cages of two cadavers to compare their spleen sizes. He observed numerous surgeries, including a ten-hour procedure where a diseased pancreas was removed, as well as one where a worn-out old knee was replaced by a brand new one. This hands-on investigation gives Macaulay a unique perspective to lead his readers on a visual journey through the workings of the human body.The seven sections within the book take us from the cells that form our foundation to the individual systems they build. Each beautifully illustrated spread details different aspects of our complex structure, explaining the function of each and offering up-close glimpses, unique cross-sections and perspectives, and even a little humor along the way.This one-of-a-kind book can serve as a reference for children, families, teachers, and anyone who has questions about how his or her body works. When readers see how David Macaulay builds a body and explains the way it works, they will come away with a new appreciation of the amazing world inside them.

    Yet, while common, oak woodlands are anything but ordinary. In a book rich in illustration and suffused with wonder, author Kate Marianchild combines extensive research and years of personal experience to explore some of the marvelous plants and animals that the oak woodlands nurture. Acorn woodpeckers unite in marriages of up to ten mates and raise their young cooperatively. Ground squirrels roll in rattlesnake skins to hide their scent from hungry snakes. Manzanita's rust-colored, paper-thin bark peels away in time for the summer solstice, exposing sinuous contours that are cool to the touch even on the hottest day. Conveying up-to-the-minute scientific findings with a storyteller's skill, Marianchild introduces us to a host of remarkable creatures in a world close by, a world that rustles, hums, and sings with the sounds of wild things.

    That thirst will be quenched at least temporarily by the perusal of this 500-plus-page pictorial extravaganza from the folks at DK. Animal Life offers you a visitor's pass into every aspect of animal behavior, from family relationships and hunting strategies to courtship rituals and sex lives. In signature DK style, editor Charlotte Uhlenbroek presides over a rich compilation of texts, side panels, photographs, and other illustrations.

    Visiting it almost daily for one year to trace nature’s path through the seasons, he brings the forest and its inhabitants to vivid life.Each of this book’s short chapters begins with a simple observation: a salamander scuttling across the leaf litter; the first blossom of spring wildflowers. From these, Haskell spins a brilliant web of biology and ecology, explaining the science that binds together the tiniest microbes and the largest mammals and describing the ecosystems that have cycled for thousands—sometimes millions—of years. Each visit to the forest presents a nature story in miniature as Haskell elegantly teases out the intricate relationships that order the creatures and plants that call it home.Written with remarkable grace and empathy, The Forest Unseen is a grand tour of nature in all its profundity. Haskell is a perfect guide into the world that exists beneath our feet and beyond our backyards.

    Coming eighteen years after the publication of The Ants, this new volume expands our knowledge of the social insects (among them, ants, bees, wasps, and termites) and is based on remarkable research conducted mostly within the last two decades. These superorganisms—a tightly knit colony of individuals, formed by altruistic cooperation, complex communication, and division of labor—represent one of the basic stages of biological organization, midway between the organism and the entire species. The study of the superorganism, as the authors demonstrate, has led to important advances in our understanding of how the transitions between such levels have occurred in evolution and how life as a whole has progressed from simple to complex forms. Ultimately, this book provides a deep look into a part of the living world hitherto glimpsed by only a very few.

      Every spring, billions of birds sweep north, driven by ancient instincts to return to their breeding grounds. This vast parade often goes unnoticed, except in a few places where these small travelers concentrate in large numbers. One such place is along Lake Erie in northwestern Ohio. There, the peak of spring migration is so spectacular that it attracts bird watchers from around the globe, culminating in one of the world’s biggest birding festivals.     Millions of winged migrants pass through the region, some traveling thousands of miles, performing epic feats of endurance and navigating with stunning accuracy. Now climate change threatens to disrupt patterns of migration and the delicate balance between birds, seasons, and habitats. But wind farms—popular as green energy sources—can be disastrous for birds if built in the wrong places. This is a fascinating and urgent study of the complex issues that affect bird migration.
