    Written by a passionate and professional geologist who has spent countless hours in the field exploring and photographing the state, In Search of Ancient Oregon is a book for all those interested in Oregon's landscapes and environments. It presents fine-art-quality color photographs of well-known features such as Mount Hood, Crater Lake, Smith Rock, Steens Mountain, the Columbia River Gorge, and Cannon Beach, and scenic, not so well known places such as Jordan Craters, Leslie Gulch, Abert Rim, Hells Canyon, Elkhorn Mountains, and Three Fingered Jack. Each of the more than 220 stunning photographs is accompanied by readable text, presenting the story of how Oregon's diverse landscapes evolved — and what we may expect in the future. Until now, no book has presented this dynamic story in a way that everyone interested in Oregon's natural history can easily understand. The combination of extraordinary photographs and the author's lucid explanations make this book both unique and essential for those curious about our own contemporary landscape.

    From the tenth to the fifteenth centuries the earth experienced a rise in surface temperature that changed climate worldwide—a preview of today's global warming. In some areas, including Western Europe, longer summers brought bountiful harvests and population growth that led to cultural flowering. In the Arctic, Inuit and Norse sailors made cultural connections across thousands of miles as they traded precious iron goods. Polynesian sailors, riding new wind patterns, were able to settle the remotest islands on earth. But in many parts of the world, the warm centuries brought drought and famine. Elaborate societies in western and central America collapsed, and the vast building complexes of Chaco Canyon and the Mayan Yucatan were left empty.As he did in his bestselling The Little Ice Age, anthropologist and historian Brian Fagan reveals how subtle changes in the environment had far-reaching effects on human life, in a narrative that sweeps from the Arctic ice cap to the Sahara to the Indian Ocean. The history of the Great Warming of a half millennium ago suggests that we may yet be underestimating the power of climate change to disrupt our lives today—and our vulnerability to drought, writes Fagan, is the "silent elephant in the room."Learn more at www.brianfagan.com.Brian Fagan discusses The Great Warming on The Daily Show with John Stewart.PRAISE for The Great Warming:"This is not only World History at its best, sweeping across all of humankind with a coherent vision, but also a feat of imagination and massive research. If Fagan has given the medieval period throughout the globe a new dimension, he has at the same time issued an irrefutable warning about climate change that is deeply troubling."—Theodore Rabb, author of The Last Days of the Renaissance"Climate has been making history for a very long time, though historians have rarely paid much attention to it. But as it turns out, a few less inches of rain, a change in temperature of just a degree or two can make all the difference in how human events unfold. The Great Warming demonstrates that although human beings make history, they very definitely do not make it under circumstances of their own choosing.”—Ted Steinberg, author of Down to Earth: Nature’s Role in American History and American Green: The Obsessive Quest for the Perfect Lawn

    If you've been searching for a basic text on how the atom works, this is it." --Booklist "A masterpiece."--OmniThe legendary Isaac Asimov starts what is perhaps the most fascinating of all his books with a simple query: how finely can a piece of matter be divided? But like many simple questions, this one leads us on a far-flung quest for a final answer, a search that becomes a series of beautifully structured building blocks of knowledge.It begins with the earliest speculations and investigations by the Greeks and Romans, and then, step by step and century by century, it traces the path of discovery that revealed more and more of the nature of the atom, of light, of gravity, of the electromagnetic force--and even the nature and structure of the universe.Atom also encompasses such phenomena as light and electricity; the protons, neutrons and quarks that are the fundamental units of the universe; hard-to-observe "anti-particles"; and other strange bits of matter that challenge our assumptions about the very nature of space and time.Atom is the only book of its kind, by the renowned author whose genius for bringing clarity and excitement to complex subjects has made him the most celebrated science author of our time.

    This compelling book introduces a bold new theory on this unsolved mystery. Author Richard Klein reexamines the archaeological evidence and brings in new discoveries in the study of the human brain. These studies detail the changes that enabled humans to think and behave in far more sophisticated ways than before, resulting in the incredibly rapid evolution of new skills. Richard Klein has been described as "the premier anthropologist in the country today" by Evolutionary Anthropology. Here, he and coauthor Blake Edgar shed new light on the full story of a truly fascinating period of evolution.Richard G. Klein, PhD (Palo Alto, CA), is a Professor of Anthropology at Stanford University. He is the author of the definitive academic book on the subject of the origins of human culture, The Human Career. Blake Edgar (San Francisco, CA) is the coauthor of the very successful From Lucy to Language, with Dr. Donald Johanson. He has written extensively for Discover, GEO, and numerous other magazines.

    Over the last three decades the theory has been repeatedly revised to address such issues as how galaxies and stars first formed and why the expansion of the universe is speeding up today. Furthermore, an explanation has yet to be found for what caused the Big Bang in the first place.In Endless Universe, Paul J. Steinhardt and Neil Turok, both distinguished theoretical physicists, present a bold new cosmology. Steinhardt and Turok “contend that what we think of as the moment of creation was simply part of an infinite cycle of titanic collisions between our universe and a parallel world” (Discover). They recount the remarkable developments in astronomy, particle physics, and superstring theory that form the basis for their groundbreaking “Cyclic Universe” theory. According to this theory, the Big Bang was not the beginning of time but the bridge to a past filled with endlessly repeating cycles of evolution, each accompanied by the creation of new matter and the formation of new galaxies, stars, and planets.Endless Universe provides answers to longstanding problems with the Big Bang model, while offering a provocative new view of both the past and the future of the cosmos.  It is a “theory that could solve the cosmic mystery” (USA Today).

    Stengers and Prigogine show how the two great themes of classic science, order and chaos, which coexisted uneasily for centuries, are being reconciled in a new and unexpected synthesis.

    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.

    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.
