Trefil's preeminent reputation for explaining complex, scientific principles in an engaging and lucid manner results in a most fascinating and elegantly guided tour through mountains and the natural and scientific world. 23 black-and-white photographs. 71 line drawings.

The third and final book in the Natural Philospher trilogy addresses the puzzles overhead: the mystery of the disappearing sunspots, why sunsets and geraniums are red, how bad clouds crashed Delta Flight 191, why we'll never see a Hurricane Zelda, the riddle of ball lightning and UFOs, and more.

Like the adventurer who circled an iceberg to see it on all sides, Mariana Gosnell, former Newsweek reporter and author of Zero Three Bravo, a book about flying a small plane around the United States, explores ice in all its complexity, grandeur, and significance.More brittle than glass, at times stronger than steel, at other times flowing like molasses, ice covers 10 percent of the earth’s land and 7 percent of its oceans. In nature it is found in myriad forms, from the delicate needle ice that crunches underfoot in a winter meadow to the massive, centuries-old ice that forms the world’s glaciers. Scientists theorize that icy comets delivered to Earth the molecules needed to get life started, and ice ages have shaped much of the land as we know it.Here is the whole world of ice, from the freezing of Pleasant Lake in New Hampshire to the breakup of a Vermont river at the onset of spring, from the frozen Antarctic landscape that emperor penguins inhabit to the cold, watery route bowhead whales take between Arctic ice floes. Mariana Gosnell writes about frostbite and about the recently discovered 5,000-year-old body of a man preserved in an Alpine glacier. She discusses the work of scientists who extract cylinders of Greenland ice to study the history of the earth’s climate and try to predict its future. She examines ice in plants, icebergs, icicles, and hail; sea ice and permafrost; ice on Mars and in the rings of Saturn; and several new forms of ice developed in labs. She writes of the many uses humans make of ice, including ice-skating, ice fishing, iceboating, and ice climbing; building ice roads and seeding clouds; making ice castles, ice cubes, and iced desserts. Ice is a sparkling illumination of the natural phenomenon whose ebbs and flows over time have helped form the world we live in. It is a pleasure to read, and important to read—for its natural science and revelations about ice’s influence on our everyday lives, and for what it has to tell us about our environment today and in the future.

"Uncommon and refreshing. Moreover, Trefil is right." -Michael Ruse, The New York Times Book Review As a prizewinning theoretical physicist and bestselling author, James Trefil has long been the public's guide to a better understanding of the world. Now, in this provocative and engaging book, Trefil looks squarely at our environmental future and finds-contrary to popular wisdom-reason to celebrate. For too long, Trefil argues, humans have treated nature as something separate from themselves-pristine wilderness to be saved or material resources to be exploited. What we need instead is a scientific approach to the environment. In Human Nature, Trefil exposes the benefits of genetically modified species, uncovers vital facts about droughts and global warming, and shows why putting humans first is the best path ahead. By taking advantage of explosive advances in the sciences, we can fruitfully manage the planet, if we rise to the challenge. Human Nature promises to awaken a new state of environmentalism and our relationship to the planet-and is filled with optimism, rather than alarm.

Whether in the bleakest moment of bidding goodbye to her dying father or in the pain she hears as she counsels gay youth, Tarbox's ears and eyes are attuned to the hopes and the solace that she finds in nature -- in the gentle sounds in a stand of pines, in the intensive chore of splitting wood. These meditations will comfort and inspire. Part of the UUA Meditation Manual series.

God only knows what possessed Bill Bryson, a reluctant adventurer if ever there was one, to undertake a gruelling hike along the world's longest continuous footpath—The Appalachian Trail. The 2,000-plus-mile trail winds through 14 states, stretching along the east coast of the United States, from Georgia to Maine. It snakes through some of the wildest and most spectacular landscapes in North America, as well as through some of its most poverty-stricken and primitive backwoods areas. With his offbeat sensibility, his eye for the absurd, and his laugh-out-loud sense of humour, Bryson recounts his confrontations with nature at its most uncompromising over his five-month journey. An instant classic, riotously funny, A Walk in the Woods will add a whole new audience to the legions of Bill Bryson fans.
