It's ever-present. Without it, you would die in minutes. And it has an epic story to tell.In Caesar's Last Breath, New York Times bestselling author Sam Kean takes us on a journey through the periodic table, around the globe, and across time to tell the story of the air we breathe, which, it turns out, is also the story of earth and our existence on it.With every breath, you literally inhale the history of the world. On the ides of March, 44 BC, Julius Caesar died of stab wounds on the Senate floor, but the story of his last breath is still unfolding; in fact, you're probably inhaling some of it now. Of the sextillions of molecules entering or leaving your lungs at this moment, some might well bear traces of Cleopatra's perfumes, German mustard gas, particles exhaled by dinosaurs or emitted by atomic bombs, even remnants of stardust from the universe's creation.Tracing the origins and ingredients of our atmosphere, Kean reveals how the alchemy of air reshaped our continents, steered human progress, powered revolutions, and continues to influence everything we do. Along the way, we'll swim with radioactive pigs, witness the most important chemical reactions humans have discovered, and join the crowd at the Moulin Rouge for some of the crudest performance art of all time. Lively, witty, and filled with the astounding science of ordinary life, Caesar's Last Breath illuminates the science stories swirling around us every second.

    These essays, first published in 1990, stand as the mature centerpiece of Snyder’s work and thought, and this profound collection is widely accepted as one of the central texts on wilderness and the interaction of nature and culture. As the Library Journal affirmed, “This is an important book for anyone interested in the ethical interrelationships of things, places, and people, and it is a book that is not just read but taken in.”

    As the forerunner of such important books as Annie Dillard's Pilgrim at Tinker Creek, Edward Abbey's Desert Solitaire, and Robert Finch's The Primal Place, this classic work remains as relevant today as it was sixty-five years ago.

    By exploring the ecological and economic changes that made Chicago America's most dynamic city and the Great West its hinterland, Mr. Cronon opens a new window onto our national past. This is the story of city and country becoming ever more tightly bound in a system so powerful that it reshaped the American landscape and transformed American culture. The world that emerged is our own.Winner of the Chicago Tribune Heartland Prize

    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.

    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.

    What exactly is the meaning of all those stone walls in the middle of the forest? Why do beech and birch trees have smooth bark when the bark of all other northern species is rough? How do you tell the age of a beaver pond and determine if beavers still live there? Why are pine trees dominant in one patch of forest and maples in another? What happened to the American chestnut? Turn to this book for the answers, and no walk in the woods will ever be the same.

    Exceptional Coverage. This authoritative volume starts with a clear introduction to the animal world, examining the reasons for the apparently infinite variety of animal forms and major evolutionary developments. Animal anatomy, life cycles and the principles of classification are also explored. This is followed by a superbly illustrated survey of world habitats, showing how they have adapted to each environment, and the threats that face both wildlife and plants today. The main part of the book, an up-to-date and comprehensive animal catalog, looks in detail at each major group and provides fascinating profiles of over 2,000 individual species. Visually Breathtaking. Spectacular photographic portraits bring a vast array of animals vividly to life, with special features on well-known and important animals such as the Galapagos tortoise. Each species profile is supported by maps and symbols showing distribution and habitat, as well as key information on size, population, and conservation status, forming an invaluable reference database. Outstanding Reference. Clear, comprehensive, and thought provoking, the Smithsonian Animal is essential reading for wildlife enthusiasts of all ages and levels of experience.

    Told by a geologist with a novelist's sense of language and narrative, Sand examines the science—sand forensics, the physics of granular materials, sedimentology, paleontology and archaeology, planetary exploration—and at the same time explores the rich human context of sand. Interwoven with tales of artists, mathematicians, explorers, and even a vampire, the story of sand is an epic of environmental construction and destruction, an adventure in staggering scales of time and distance, yet a tale that encompasses the ordinary and everyday. Sand, in fact, is all around us—it has made possible our computers, buildings and windows, toothpaste, cosmetics, and paper, and it has played dramatic roles in human history, commerce, and imagination. In this luminous, kinetic, revelatory account, we do indeed find the world in a grain of sand.

    With black and white illustrations. "Here is a new collection of Gould's unexpected connections between evolution and all manner of subjects, literature high among them. Gathered from his monthly column in "Natural History" magazine, these articles should delight, surprise, and inform his vast readership, as have his six prior volumes of essays. Somehow the light bulb pops on every month as his deadline approaches, some glowing fact pulled out of memory--often a line from Shakespeare or Tennyson--that illumines a generality Gould wishes to discuss. "Nature, red in tooth and claw" (Lord Alfred's line) induces dilations on the extent science can inform moral matters (not much, Gould believes); a remembrance of the infamous Wansee protocol prompts Gould's denunciation of the genocidal looting of evolutionary theory and, by extension, its vulnerability to ignoramuses in general. These two examples of the Gouldian essay method, fortunately, don't foreshadow a gloomy parade of topics: Gould can as easily alight at the fun house where mass culture absorbs ideas about evolution through movies of monsters run amok from Frankenstein to Jurassic Park. In other essays, he plunges directly into matters of evolutionary interpretation but customarily employs a literary twist: who else but Gould could link Edgar Allan Poe with his own area of professional eminence, the paleontology of snails? A discovery awaits in every essay--in every haystack--which solidifies Gould as one of the most eloquent science popularizers writing today."--"Booklist"

    The book documents the adverse environmental effects caused by the indiscriminate use of pesticides. Carson accused the chemical industry of spreading disinformation, and public officials of accepting the industry's marketing claims unquestioningly.The book appeared in September 1962 and the outcry that followed its publication forced the banning of DDT and spurred revolutionary changes in the laws affecting our air, land, and water. Carson’s book was instrumental in launching the environmental movement.

    It floats like a jewel in the inky black void. The reflection of the suns light from the vast expanse of water covering its surface creates its gem-like blue colour. In the entire solar system Earth is the only planet that has water in its liquid form in such quantities. Scientists have calculated that 70% of our planet is covered by water; small wonder then that humans have always been so fascinated by the oceans and what lies beneath. Today while we still have so much more of the ocean realm to uncover we have discovered enough to know that beneath the waves lies a vast treasure-trove of rich and diverse life. The Blue Planet leads us on a voyage of exploration from the coasts, the very edges of the oceans, to the deep where weird and monstrous fish lurk in a world of perpetual darkness. Along the way we meet a host of wonderful creatures from tiny copepods to majestic blue whales, from the grotesque hairy anglerfish, to the amazing tripod fish that stands on 3 delicate legs waiting to snap up unsuspecting prey. With a foreword by David Attenborough and 400 colour photos The Blue Planet is the first complete and comprehensive portrait of the whole ocean system.

    The Los Angeles Times has listed it among the one hundred most influential books published in the last quarter century, Outside Magazine has included it in a survey of books that changed our world, and it has been called the Book of Genesis for environmentalists. Now a fourth edition of this highly regarded work is available, with a new preface and epilogue in which Nash explores the future of wilderness and reflects on its ethical and biocentric relevance.

    Whether William Bryant Logan is traversing the far reaches of the cosmos or plowing through our planet’s crust, his delightful, elegant, and surprisingly soulful meditations greatly enrich our concept of "dirt," that substance from which we all arise and to which we all must return.
