    To his contemporaries he was a minor disciple of Emerson; he has since joined the ranks of America's most respected and beloved writers. Few, however, really know the complexity of the man they revere — wanderer and scholar, naturalist and humorist, teacher and surveyor, abolitionist and poet, Transcendentalist and anthropologist, inventor and social critic, and, above all, individualist.In this widely acclaimed biography, outstanding Thoreau scholar Walter Harding presents all of these Thoreaus. Scholars will find here the culmination of a lifetime of research and study, meticulously documented; general readers will find an absorbing story of a remarkable man. Writing always with supreme clarity, Professor Harding has marshaled all the facts so as best to "let them speak for themselves." Thoreau's thoughtfulness and stubbornness, his more than ordinarily human amalgam of the earthy and the sublime, his unquenchable vitality emerge to the reader as they did to his own family, friends, and critics.You will see Thoreau's work in his family's pencil factory, his accidental setting of a forest fire, his love of children and hatred of hypocrisy, his contributions to the scientific understanding of forest trees, and other more and less familiar aspects of the man and his works. You will find the social as well as the reclusive Thoreau. Reactions to him by such notable contemporaries as Margaret Fuller, Nathaniel Hawthorne, and Walt Whitman — with Thoreau's responses to them — are given in rich detail.The totality is as complete, accurate, fair, vivid, and fully rounded a portrait as has ever been drawn. On its appearance, Professor Harding's work immediately established itself as "the standard biography" (Edward Wagenknecht). It has never been superseded. For this Dover edition, the author has corrected minor errors, provided an appendix bibliographically documenting hundreds of facts, and contributed an Afterword updating some of his findings and discussing Thoreau scholarship.

    Taking as territory everything from the Big Bang to the rise of civilization, Bryson seeks to understand how we got from there being nothing at all to there being us. To that end, he has attached himself to a host of the world’s most advanced (and often obsessed) archaeologists, anthropologists, and mathematicians, travelling to their offices, laboratories, and field camps. He has read (or tried to read) their books, pestered them with questions, apprenticed himself to their powerful minds. A Short History of Nearly Everything is the record of this quest, and it is a sometimes profound, sometimes funny, and always supremely clear and entertaining adventure in the realms of human knowledge, as only Bill Bryson can render it. Science has never been more involving or entertaining.

    Yet this enigmatic animal is more complex than the legends that surround it. With a shrinking wilderness and global warming, the future of the wolverine is uncertain. The Wolverine Way reveals the natural history of this species and the forces that threaten its future, engagingly told by Douglas Chadwick, who volunteered with the Glacier Wolverine Project. This five-year study in Glacier National Park – which involved dealing with blizzards, grizzlies, sheer mountain walls, and other daily challenges to survival – uncovered key missing information about the wolverine’s habitat, social structure and reproduction habits. Wolverines, according to Chadwick, are the land equivalent of polar bears in regard to the impacts of global warming. The plight of wolverines adds to the call for wildlife corridors that connect existing habitat that is proposed by the Freedom to Roam coalition.

    

    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.

    She draws on conversations with hundreds of the world's top scientists and on her own work as a Pulitzer Prize-winning writer for the New York Times to create a thoroughly entertaining guide to scientific literacy. Angier's gifts are on full display in The Canon, an ebullient celebration of science that stands to become a classic. The Canon is vital reading for anyone who wants to understand the great issues of our time -- from stem cells and bird flu to evolution and global warming. And it's for every parent who has ever panicked when a child asked how the earth was formed or what electricity is. Angier's sparkling prose and memorable metaphors bring the science to life, reigniting our own childhood delight in discovering how the world works. "Of course you should know about science," writes Angier, "for the same reason Dr. Seuss counsels his readers to sing with a Ying or play Ring the Gack: These things are fun and fun is good." The Canon is a joyride through the major scientific disciplines: physics, chemistry, biology, geology, and astronomy. Along the way, we learn what is actually happening when our ice cream melts or our coffee gets cold, what our liver cells do when we eat a caramel, why the horse is an example of evolution at work, and how we're all really made of stardust. It's Lewis Carroll meets Lewis Thomas -- a book that will enrapture, inspire, and enlighten.

    Europe suffered through a record freeze as the American West was hit with massive floods and snowstorms; in the western Pacific, meanwhile, some island nations literally went bone dry and had to have water flown in on transport planes.Such effects are not new: climatologists now know the El Niño and other climate anomalies have been disrupting weather patterns throughout history. But until recently, no one had asked how this new understanding of the global weather system related to archaeology and history. Droughts, floods, heat and cold put stress on cultures and force them to adapt. What determines whether they adapt successfully? How do these climate stresses affect a people's faith in the foundations of their society and the legitimacy of their rulers? How vulnerable is our own society to climate change?In this dazzlingly original new book, archaeologist Brian Fagan shows that short-term climate shifts have been a major—and hitherto unrecognized—force in history. El Niño-driven droughts have brought on the collapse of dynasties in Egypt; El Niño monsoon failures have caused historic famines in India; and El Niño floods have destroyed whole civilizations in Peru. Other short-term climate changes may have caused the mysterious abandonment of the Anasazi dwellings in the American Southwest and the collapse of the ancient Maya empire, as well as changed the course of European history.This beautifully written, groundbreaking book opens a new door on our understanding of historical events.

    Also known as the Yellowstone Earthquake, the disaster caused massive flooding and the worst landslide in the history of the Northwestern United States. In The Night the Mountain Fell author Edmund Christopherson gives us a page-turning, journalistic-style account of how the deadliest earthquake in Montana's history ultimately claimed the lives of twenty-eight people.

    At the time we were hoping that our approach of writing a book which would be both accessible without mathematical sophistication and portray these exiting new fields in an authentic manner would find an audience. Now we know it did. We know from many reviews and personal letters that the book is used in a wide range of ways: researchers use it to acquaint themselves, teachers use it in college and university courses, students use it for background reading, and there is also a substantial audience of lay people who just want to know what chaos and fractals are about. Every book that is somewhat technical in nature is likely to have a number of misprints and errors in its first edition. Some of these were caught and brought to our attention by our readers. One of them, Hermann Flaschka, deserves to be thanked in particular for his suggestions and improvements. This second edition has several changes. We have taken out the two appendices from the firstedition. At the time of the first edition Yuval Fishers contribution, which we published as an appendix was probably the first complete expository account on fractal image compression. Meanwhile, Yuvals book Fractal Image Compression: Theory and Application appeared and is now the publication to refer to.

    The fascinating story of how a harsh terrain that resembled modern Antarctica has been transformed gradually into the forests, grasslands, and wetlands we know today.

    Now, in this lucid and accessibly written book, Philip Ball applies state-of-the-art scientific understanding from the fields of biology, chemistry, geology, physics, and mathematics to these ancient mysteries, revealing how nature's seemingly complex patterns originate in simple physical laws. Tracing the history of scientific thought about natural patterns, Ball shows how common presumptions--for example, that complex form must be guided by some intelligence or that form always follows function--are erroneous and continue to mislead scientists today. He investigates specific patterns in depth, revealing that these designs are self-organized and that simple, local interactions between component parts produce motifs like spots, stripes, branches, and honeycombs. In the process, he examines the mysterious phenomenon of symmetry and why it appears--and breaks--in similar ways in different systems. Finally, he attempts to answer this profound question: why are some patterns universal? Illustrations throughout the text, many in full color, beautifully illuminate Ball's ideas.
