Bird-eating snakes from Australia hitchhike to Hawaii in the landing gear of airliners; disruptive European zebra mussels, riding in ships' ballast water, are infiltrating aquatic ecosystems across the United States; parasitic flies from the U.S. prey on Darwin's finches in the Galapagos. Predatory American jellyfish in Russia; toxic Japanese plankton in Australia; Burmese pythons in the Everglades-biologists refer fearfully to "the homogenization of the world" as alien species jump from place to place and increasingly crowd native and endangered species out of existence. Never mind bulldozers and pesticides: the fastest-growing threat to biological diversity may be nature itself. "Out of Eden" is a journey through this strange and shifting landscape. The author tours the front lines of ecological invasion--in Hawaii, Tasmania, Guam, San Francisco; in lush rainforests, through underground lava tubes, on the deck of an Alaska-bound oil tanker--in the company of world-class scientists. Wry and reflective, animated and richly reported, "Out of Eden" is a search both for scientific answers and for ecological authenticity.

    In the 1990s he and his colleagues made headlines with the discovery that the last ice age came to an abrupt end over a period of only three years. Here Alley offers the first popular account of the wildly fluctuating climate that characterized most of prehistory--long deep freezes alternating briefly with mild conditions--and explains that we humans have experienced an unusually temperate climate. But, he warns, our comfortable environment could come to an end in a matter of years."The Two-Mile Time Machine" begins with the story behind the extensive research in Greenland in the early 1990s, when scientists were beginning to discover ancient ice as an archive of critical information about the climate. Drilling down two miles into the ice, they found atmospheric chemicals and dust that enabled them to construct a record of such phenomena as wind patterns and precipitation over the past 110,000 years. The record suggests that "switches" as well as "dials" control the earth's climate, affecting, for example, hot ocean currents that today enable roses to grow in Europe farther north than polar bears grow in Canada. Throughout most of history, these currents switched on and off repeatedly (due partly to collapsing ice sheets), throwing much of the world from hot to icy and back again in as little as a few years.Alley explains the discovery process in terms the general reader can understand, while laying out the issues that require further study: What are the mechanisms that turn these dials and flip these switches? Is the earth due for another drastic change, one that will reconfigure coastlines or send certain regions into severe drought? Will global warming combine with natural variations in Earth's orbit to flip the North Atlantic switch again? Predicting the long-term climate is one of the greatest challenges facing scientists in the twenty-first century, and Alley tells us what we need to know in order to understand and perhaps overcome climate changes in the future.

    Get ready to unthink what you thought you knew and journey into the deep, dark depths of the Jurassic.The discovery of the first feathered dinosaur in China in 1996 sent shockwaves through the palaeontological world. Were the feathers part of a complex mating ritual, or a stepping stone in the evolution of flight? And just how closely related is T. rex to a chicken? Award-winning journalist John Pickrell reveals how dinosaurs developed flight and became the birds in our backyards. He delves into the latest discoveries in China, the US, Europe and uncovers a thriving black market in fossils and infighting between dinosaur hunters, plus the controversial plan to use a chicken to bring dinosaurs back from the dead.

    The result is a wealth of stimulating ideas set among clear explanations drawn from a revelatory decade in biology."—Andrew H. Knoll, author of Life on a Young Planet"Thought-provoking and lucidly written. . . . The Plausibility of Life will help readers understand not just the plausibility of evolution, but its remarkable, inventive powers." —Sean Carroll, author of Endless Forms Most Beautiful: The New Science of Evo Devo“Remarkably lucid and comprehensive, this new theoretical synthesis will . . . shift the grounds for debate in the controversy surrounding organic evolution.”—Booklist (starred review)

    Learning all the tongue twisting names, picking favorites based on ferocity, armor, or sheer size. For many kids this love of ‘terrible lizards’ fizzles out at some point between starting and leaving primary school. All those fancy names slowly forgotten, no longer any need for a favorite.For all those child dino fanatics who didn’t grow up to become paleontologists, dinosaurs seem like something out of mythology. They are dragons, pictures in books, abstract, other, extinct.They are at the same time familiar and mysterious. And yet we’re in an age of rapid discovery—new dinosaur species and genera are being discovered at an accelerating rate, we’re learning more about what they looked like, how they lived, how they evolved and where they all went.This series isn’t just a top trumps list of dino facts—we’re interested in the why and the how and like all areas of science there is plenty of controversy and debate.

    Here the German-born scientist Wernher von Braun detailed what he believed were the problems and possibilities inherent in a projected expedition to Mars.    Today von Braun is recognized as the person most responsible for laying the groundwork for public acceptance of America's space program. When President Bush directed NASA in 1989 to prepare plans for an orbiting space station, lunar research bases, and human exploration of Mars, he was largely echoing what von Braun proposed in The Mars Project.

    De Waal reminds readers through his account of the chimps' sexual rivalries and coalitions, and intelligent rather than instinctual actions, that the roots of politics are older than humanity.

    By the time of his death in 1859, he had won international fame for his scientific discoveries, his observations of Native American peoples and his detailed descriptions of the flora and fauna of the 'new continent'. The first to draw and speculate on Aztec art, to observe reverse polarity in magnetism and to discover why America is called America, his writings profoundly influenced the course of Victorian culture, causing Darwin to reflect: 'He alone gives any notion of the feelings which are raised in the mind on first entering the Tropics'.

    Today, unfortunately, the traditional place of mathematics in education is in grave danger. The teaching and learning of mathematics has degenerated into the realm of rote memorization, the outcome of which leads to satisfactory formal ability but does not lead to real understanding or to greater intellectual independence. This new edition of Richard Courant's and Herbert Robbins's classic work seeks to address this problem. Its goal is to put the meaning back into mathematics.Written for beginners and scholars, for students and teachers, for philosophers and engineers, What is Mathematics? Second Edition is a sparkling collection of mathematical gems that offers an entertaining and accessible portrait of the mathematical world. Covering everything from natural numbers and the number system to geometrical constructions and projective geometry, from topology and calculus to matters of principle and the Continuum Hypothesis, this fascinating survey allows readers to delve into mathematics as an organic whole rather than an empty drill in problem solving. With chapters largely independent of one another and sections that lead upward from basic to more advanced discussions, readers can easily pick and choose areas of particular interest without impairing their understanding of subsequent parts.Brought up to date with a new chapter by Ian Stewart, What is Mathematics? Second Edition offers new insights into recent mathematical developments and describes proofs of the Four-Color Theorem and Fermat's Last Theorem, problems that were still open when Courant and Robbins wrote this masterpiece, but ones that have since been solved.Formal mathematics is like spelling and grammar - a matter of the correct application of local rules. Meaningful mathematics is like journalism - it tells an interesting story. But unlike some journalism, the story has to be true. The best mathematics is like literature - it brings a story to life before your eyes and involves you in it, intellectually and emotionally. What is Mathematics is like a fine piece of literature - it opens a window onto the world of mathematics for anyone interested to view.

    They have also become vibrant educational centers, full of engaging exhibits that share those discoveries with students and an enthusiastic general public.   At the heart of it all from the very start have been curators. Yet after three decades as a natural history curator, Lance Grande found that he still had to explain to people what he does. This book is the answer—and, oh, what an answer it is: lively, exciting, up-to-date, it offers a portrait of curators and their research  like none we’ve seen, one that conveys the intellectual excitement and the educational and social value of curation. Grande uses the personal story of his own career—most of it spent at Chicago’s storied Field Museum—to structure his account as he explores the value of research and collections, the importance of public engagement, changing ecological and ethical considerations, and the impact of rapidly improving technology. Throughout, we are guided by Grande’s keen sense of mission, of a job where the why is always as important as the what.   This beautifully written and richly illustrated book is a clear-eyed but loving account of natural history museums, their curators, and their ever-expanding roles in the twenty-first century.

    

    From India's sacred banyan tree to the fragrant cedar of Lebanon, they offer us sanctuary and inspiration – not to mention the raw materials for everything from aspirin to maple syrup.In Around the World in 80 Trees, expert Jonathan Drori uses plant science to illuminate how trees play a role in every part of human life, from the romantic to the regrettable. Stops on the trip include the lime trees of Berlin's Unter den Linden boulevard, which intoxicate amorous Germans and hungry bees alike, the swankiest streets in nineteenth-century London, which were paved with Australian eucalyptus wood, and the redwood forests of California, where the secret to the trees' soaring heights can be found in the properties of the tiniest drops of water.Each of these strange and true tales – populated by self-mummifying monks, tree-climbing goats and ever-so-slightly radioactive nuts – is illustrated by Lucille Clerc, taking the reader on a journey that is as informative as it is beautiful.

    It is a tale of rivers diverted and dammed, of political corruption and intrigue, of billion-dollar battles over water rights, of ecologic and economic disaster. In Cadillac Desert Marc Reisner writes of the earliest settlers, lured by the promise of paradise, and of the ruthless tactics employed by Los Angeles politicians and business interests to ensure the city's growth. He documents the bitter rivalry between two government giants, the Bureau of Reclamation and the U.S. Army Corps of Engineers, in the competition to transform the West.Based on more than a decade of research, Cadillac Desert is a stunning expose and a dramatic, intriguing history of the creation of an Eden—an Eden that may be only a mirage.

    Around 95% of all living species died out--a global catastrophe far greater than the dinosaurs' demise 65 million years ago. How this happened remains a mystery. But there are many competing theories. Some blame huge volcanic eruptions that covered an area as large as the continental United States; others argue for sudden changes in ocean levels and chemistry, including burps of methane gas; and still others cite the impact of an extraterrestrial object, similar to what caused the dinosaurs' extinction. Extinction is a paleontological mystery story. Here, the world's foremost authority on the subject provides a fascinating overview of the evidence for and against a whole host of hypotheses concerning this cataclysmic event that unfolded at the end of the Permian.After setting the scene, Erwin introduces the suite of possible perpetrators and the types of evidence paleontologists seek. He then unveils the actual evidence--moving from China, where much of the best evidence is found; to a look at extinction in the oceans; to the extraordinary fossil animals of the Karoo Desert of South Africa. Erwin reviews the evidence for each of the hypotheses before presenting his own view of what happened.Although full recovery took tens of millions of years, this most massive of mass extinctions was a powerful creative force, setting the stage for the development of the world as we know it today.
