216-page Softcover.Introduction to Permaculture is an updated and revised version of the first two permaculture books, Permaculture One (Mollison and Holmgren, 1978) and Permaculture Two (Mollison, 1979), and replaces them. New material by Bill Mollison and Reny Mia Slay has been inserted, along with excerpts from Permaculture: A Designers' Manual and information taken from permaculture design courses taught by Bill Mollison (1981, 1986) and Lea Harrison (1985). Some of the illustrations in this book have appeared in Permaculture Two and Permaculture: A Designers' Manual.

    Together, they explain virtually everything about the world we live in. But, almost a century after their advent, most people haven't the slightest clue what either is about. Did you know that there's so much empty space inside matter that the entire human race could be squeezed into the volume of a sugar cube? Or that you grow old more quickly on the top floor of a building than on the ground floor? And did you realize that 1 per cent of the static on a TV tuned between stations is the relic of the Big Bang? These and many other remarkable facts about the world are direct consequences of quantum physics and relativity. Quantum theory has literally made the modern world possible. Not only has it given us lasers, computers, and nuclear reactors, but it has provided an explanation of why the sun shines and why the ground beneath our feet is solid. Despite this, however, quantum theory and relativity remain a patchwork of fragmented ideas, vaguely understood at best and often utterly mysterious. average person. Author Marcus Chown emphatically disagrees. As Einstein himself said, Most of the fundamental ideas of science are essentially simple and may, as a rule, be expressed in a language comprehensible to everyone. If you think that the marvels of modern physics have passed you by, it is not too late. In Chown's capable hands, quantum physics and relativity are not only painless but downright fun. So sit back, relax, and get comfortable as an adept and experienced science communicator brings you quickly up to speed on some of the greatest ideas in the history of human thought.

    Its clinicopathologic orientation highlights the impact of molecular pathology on the practice of medicine. And, it integrates clinical and anatomic pathology, and discusses laboratory diagnosis of specific disorders.

    Now in its fourth edition, the work has been extensively revised, with entirely new artwork, updated examples and new pedagogical features. An interactive CD-ROM with worked examples is included. Alternatively, the material on from the CD-ROM can be down-loaded from a website (see supplements section). Twentieth-century developments such as quantum mechanics are introduced early on, so that students can appreciate their importance and see how they fit into the bigger picture.

    It condenses a huge amount of information about tree identification--more than has ever been collected in a single book--into a logical, accessible, easy-to-use format.With more than 4,100 meticulous, exquisitely detailed paintings, the Guide highlights the often subtle similarities and distinctions between more than 600 tree species--native trees as well as many introduced species. No other guide has ever made field identification so clear.Features highlighted include: - leaves (including multiple leaf shapes and fall leaf color)- bark- needles- cones- flowers- fruit- twigs- silhouettesMore than 500 maps show the complete range, both natural and cultivated, for nearly all species.Trees are arranged taxonomically, with all related species grouped together. By focusing on the fundamental characteristics of, for example, oaks or chestnuts or hickories, the Guide helps the user recognize these basic species groups the same way birders recognize thrushes, warblers, or sparrows.In addition, there are essays on taxonomy, on the cultivation of trees, and on conservation issues, reflecting Sibley's deep concern with habitat preservation and environmental health.An important new contribution to our understanding of the natural world, The Sibley Guide to Trees will be a necessity for every tree lover, traveler, and naturalist. It is sure to become the new benchmark in field guides to trees.

    With artwork from Katie Scott of Animalium fame, Botanicum gives readers the experience of a fascinating exhibition from the pages of a beautiful book. From perennials to bulbs to tropical exotica, Botanicum is a wonderful feast of botanical knowledge complete with superb cross sections of how plants work.

    Yet there is much more to the monarch than its distinctive presence and mythic journeying. In Monarchs and Milkweed, Anurag Agrawal presents a vivid investigation into how the monarch butterfly has evolved closely alongside the milkweed--a toxic plant named for the sticky white substance emitted when its leaves are damaged--and how this inextricable and intimate relationship has been like an arms race over the millennia, a battle of exploitation and defense between two fascinating species.The monarch life cycle begins each spring when it deposits eggs on milkweed leaves. But this dependency of monarchs on milkweeds as food is not reciprocated, and milkweeds do all they can to poison or thwart the young monarchs. Agrawal delves into major scientific discoveries, including his own pioneering research, and traces how plant poisons have not only shaped monarch-milkweed interactions but have also been culturally important for centuries. Agrawal presents current ideas regarding the recent decline in monarch populations, including habitat destruction, increased winter storms, and lack of milkweed--the last one a theory that the author rejects. He evaluates the current sustainability of monarchs and reveals a novel explanation for their plummeting numbers.Lavishly illustrated with more than eighty color photos and images, Monarchs and Milkweed takes readers on an unforgettable exploration of one of nature's most important and sophisticated evolutionary relationships.

    In the new edition of Biochemistry, instructors will see the all the hallmark features that made this a consistent bestseller for the undergraduate biochemistry course: exceptional clarity and concision, a more biological focus, cutting-edge content, and an elegant, uncluttered design.  Accomplished in both the classroom and the laboratory, coauthors Jeremy Berg and John Tymoczko draw on the field's dynamic research to illustrate its fundamental ideas.

    This book presents novel scientific information in a way that beginning hobbyists can use it to set up and maintain planted freshwater aquariaAbout The Author:The author is a medical research technician, former technical advisor for the Aquatic Gardeners Association, and a long time aquarium hobbyist.

    The trilobites, which dominated the ocean floors for 300 million years, are gone. The last of the dinosaurs was wiped out by a Mount Everest-sized meteorite that slammed into the earth 65 million years ago. The great flying reptiles are gone, and so are the marine reptiles, some of them larger than a humpback whale. Before humans crossed the Bering land bridge some 15,000 years ago, North America was populated by mastodons, mammoths, saber-toothed tigers, and cave bears. They too are MIA. Passenger pigeons once flew over North America in flocks that numbered in the billions; the last one died in 1914.In this book you will meet creatures that were driven to extinction even more recently, as well as some that were brought back from the brink. You will even encounter animals not known to exist until recently -- an antidote to extinction.

    This book will offer students a broad outline of essential mathematics and will help to fill in the gaps in their knowledge. The author explains the basic points and a few key results of all the most important undergraduate topics in mathematics, emphasizing the intuitions behind the subject. The topics include linear algebra, vector calculus, differential and analytical geometry, real analysis, point-set topology, probability, complex analysis, set theory, algorithms, and more. An annotated bibliography offers a guide to further reading and to more rigorous foundations.

    It strikes a balance between theory and application by incorporating real-world examples; helping students visualize the three-dimensional atomic and molecular structures that are the basis of chemical activity; and developing problem-solving and critical thinking skills. Although the fifth edition incorporates many new features, such as macro to micro artwork, six new animations correlated to the text, and the addition of new hand-sketched worked examples, General Chemistry is still 200 to 300 pages shorter and much less expensive than other two-semester textbooks. Dr. Chang's concise-but-thorough approach will appeal to efficiency-minded instructors and value-conscious students.

    For centuries these supremely adaptable, generous trees have supported humankind in nearly every facet of life. From the ink of Bach’s cantatas to the first boat to reach the New World, the wagon, the barrel, and the sword, oak trees have been a constant presence in our past. Yet we’ve largely forgotten the oak’s role in civilization. With reverence, humor, and compassion, Logan awakens us to the vibrant presence of the oak throughout our history and in today’s world.

    It is the root of our existence, supporting our feet, our farms, our cities. This fascinating yet disquieting book finds, however, that we are running out of dirt, and it's no laughing matter. An engaging natural and cultural history of soil that sweeps from ancient civilizations to modern times, Dirt: The Erosion of Civilizations explores the compelling idea that we are—and have long been—using up Earth's soil. Once bare of protective vegetation and exposed to wind and rain, cultivated soils erode bit by bit, slowly enough to be ignored in a single lifetime but fast enough over centuries to limit the lifespan of civilizations. A rich mix of history, archaeology and geology, Dirt traces the role of soil use and abuse in the history of Mesopotamia, Ancient Greece, the Roman Empire, China, European colonialism, Central America, and the American push westward. We see how soil has shaped us and we have shaped soil—as society after society has risen, prospered, and plowed through a natural endowment of fertile dirt. David R. Montgomery sees in the recent rise of organic and no-till farming the hope for a new agricultural revolution that might help us avoid the fate of previous civilizations.

    Heinrich has spent a lifetime observing the natural world, and now he shares his vast knowledge and reflections on the trees of the Northeast woods and the rhythms of their seasons.From the DNA contained in an apple seed to the great choiring branches far beyond a young boy's reach, Heinrich explores a natural world in scientific and personal terms. Heinrich is a scientist, but his words speak with the power and subtle grace of a poet. He uses this gift, and his intimate knowledge of his 300 acres of Maine forest, to expose the forest's rhythms, and in doing so, illustrates the vital but tenuous link among man, trees, birds, insects, and all the creatures of the forest. Thanks to Bernd Heinrich, readers will finally see the forest and the trees.
