In this new book Hawking takes us to the cutting edge of theoretical physics, where truth is often stranger than fiction, to explain in laymen's terms the principles that control our universe. Like many in the community of theoretical physicists, Professor Hawking is seeking to uncover the grail of science - the elusive Theory of Everything that lies at the heart of the cosmos. In his accessible and often playful style, he guides us on his search to uncover the secrets of the universe - from supergravity to supersymmetry, from quantum theory to M-theory, from holography to duality. He takes us to the wild frontiers of science, where superstring theory and p-branes may hold the final clue to the puzzle. And he lets us behind the scenes of one of his most exciting intellectual adventures as he seeks "to combine Einstein's General Theory of Relativity and Richard Feynman's idea of multiple histories into one complete unified theory that will describe everything that happens in the universe." With characteristic exuberance, Professor Hawking invites us to be fellow travelers on this extraordinary voyage through space-time. Copious four-color illustrations help clarify this journey into a surreal wonderland where particles, sheets, and strings move in eleven dimensions; where black holes evaporate and disappear, taking their secret with them; and where the original cosmic seed from which our own universe sprang was a tiny nut. The Universe in a Nutshell is essential reading for all of us who want to understand the universe in which we live. Like its companion volume, A Brief History of Time, it conveys the excitement felt within the scientific community as the secrets of the cosmos reveal themselves.

    Margulis to create a vivid new picture of the world that is crucial to our understanding of the future of the planet. Addressed to general readers, the book provides a beautifully written view of evolution as a process based on interdependency and the interconnectedness of all life on the planet.

    Harlen Bretz walked the dry scabland channels of eastern Washington in the 1920s, it dawned on him that he was viewing a landscape sculpted by water. Lots of water. A flood of catastrophic proportions. Glacial Lake Missoula and Its Humongous Floods tells the gripping tale of a huge Ice Age lake that drained suddenly--not just once but repeatedly--and reshaped the landscape of the Northwest. The narrative follows the path of the floodwaters as they raged from western Montana across the Idaho Panhandle, then scoured through eastern Washington and down the Columbia Gorge to the Pacific Ocean. This is also the story of geologists grappling with scientific controversy--"of how personalities, pride, and prejudice sometimes superseded scientific evidence."

    In this extraordinary feat of nature writing, we meet ants who harvest crops, raise insects as livestock, build roadways and bridges, embark on nuptial flights, and make war.

    In what has become one of science's greatest riddles, these large animals vanished in North and South America around the time humans arrived at the end of the last great ice age. Part paleontological adventure and part memoir, Twilight of the Mammoths presents in detail internationally renowned paleoecologist Paul Martin's widely discussed and debated "overkill" hypothesis to explain these mysterious megafauna extinctions. Taking us from Rampart Cave in the Grand Canyon, where he finds himself "chest deep in sloth dung," to other important fossil sites in Arizona and Chile, Martin's engaging book, written for a wide audience, uncovers our rich evolutionary legacy and shows why he has come to believe that the earliest Americans literally hunted these animals to death.As he discusses the discoveries that brought him to this hypothesis, Martin relates many colorful stories and gives a rich overview of the field of paleontology as well as his own fascinating career. He explores the ramifications of the overkill hypothesis for similar extinctions worldwide and examines other explanations for the extinctions, including climate change. Martin's visionary thinking about our missing megafauna offers inspiration and a challenge for today's conservation efforts as he speculates on what we might do to remedy this situation—both in our thinking about what is "natural" and in the natural world itself.

    Colin Tudge argues that we are entering a new phase of biology in which, for the first time, biologists are achieving profound insight into life's true diversity and developing the tools to keep track of it. The Variety of Life heralds this new phase. The first part of the book describes why biologists now feel that there could have been as many as 4,000 billion species on Earth since life began. It then discusses the need for classification, beginning with the most basic principles--the strictly practical classification of fishmongers and foresters, who speak of "shellfish" and differentiate "hardwood" from "softwood"--and moves on to explore the intriguing deliberations of the modern "transformed cladists" and the novel contributions of molecular genetics. Part II describes the creatures themselves. It is divided into 24 sections, each describing a different group, illustrated by nearly 50 double-page spreads which present genealogical "trees" that summarize the evolutionary relationships between the creatures in each group. Some sections describe large, comprehensive groups such as the kingdoms of the Animals or the Plants. Others treat similar sub-groups in more detail, such as the Mammals, a class, or the Hominids, a family. In lively and accessible prose, all the significant groups of creatures--both alive and extinct--are described and their relationships clarified. For general readers and serious biologists alike, The Variety of Life offers an unprecedented storehouse of knowledge of life on earth.

    Wilson’s view? Recording observations in the field is an indispensable scientific skill, but researchers are not generally willing to share their personal records with others. Here, for the first time, are reproductions of actual pages from notebooks. And in essays abounding with fascinating anecdotes, the authors reflect on the contexts in which the notes were taken.Covering disciplines as diverse as ornithology, entomology, ecology, paleontology, anthropology, botany, and animal behavior, Field Notes offers specific examples that professional naturalists can emulate to fine-tune their own field methods, along with practical advice that amateur naturalists and students can use to document their adventures.

    What explains these far-flung distributions? Why are species found where they are across the Earth? Since the discovery of plate tectonics, scientists have long conjectured that plants and animals were scattered over the globe by riding pieces of ancient supercontinents as they broke up. In the past decade, however, that theory has foundered, as the genomic revolution has made reams of new genetic data available. And the data has revealed an extraordinary, stranger-than-fiction story that has sparked a scientific revolution. In The Monkey's Voyage, biologist Alan de Queiroz introduces a radical new theory of how species as diverse as monkeys, baobab trees, and burrowing lizards made incredible long-distance ocean crossings: pregnant animals and wind-blown plants rode rafts and icebergs and even stowed away on the legs of sea-going birds to create the map of life we see today. In other words, these organisms were not merely victims of continental fate; they were masters of their geographic destiny. And as de Queiroz shows, the effects of oceanic dispersal have been crucial in generating the diversity of life on Earth, from monkeys and guinea pigs in South America to beech trees and kiwi birds in New Zealand. By toppling the idea that the slow process of continental drift drove odd distributions of organisms, this new theory highlights the dynamic and unpredictable nature of the history of life. In the tradition of John McPhee’s Basin and Range, The Monkey's Voyage is a beautifully told narrative of a profound investigation into the importance of contingency in history and the nature of scientific discovery.

    Bursting with all the suspense and intrigue of a fast paced adventure novel, here is Johanson’s lively account of the extraordinary discovery of “Lucy.” By expounding the controversial change Lucy makes in our view of human origins, Johanson provides a vivid, behind-the-scenes account of the history of pealeoanthropology and the colorful, eccentric characters who were and are a part of it. Never before have the mystery and intricacy of our origins been so clearly and compellingly explained as in this astonighing and dramatic book.

    But roaming the planet are four times as many dogs who are their own masters—neighborhood dogs, dump dogs, mountain dogs. They are dogs, not companions, and these dogs, like pigeons or squirrels, are highly adapted scavengers who have evolved to fit particular niches in the vicinity of humans. In What Is a Dog? experts on dog behavior Raymond and Lorna Coppinger present an eye-opening analysis of the evolution and adaptations of these unleashed dogs and what they can reveal about the species as a whole. Exploring the natural history of these animals, the Coppingers explain how the village dogs of Vietnam, India, Africa, and Mexico are strikingly similar. These feral dogs, argue the Coppingers, are in fact the truly archetypal dogs, nearly uniform in size and shape and incredibly self-sufficient. Drawing on nearly five decades of research, they show how dogs actually domesticated themselves in order to become such efficient scavengers of human refuse. The Coppingers also examine the behavioral characteristics that enable dogs to live successfully and to reproduce, unconstrained by humans, in environments that we ordinarily do not think of as dog friendly. Providing a fascinating exploration of what it actually means—genetically and behaviorally—to be a dog, What Is a Dog? will undoubtedly change the way any beagle or bulldog owner will reflect on their four-legged friend.
