    The planet most like ours, it has still been thought impossible to reach, let alone explore and inhabit.Now with the advent of a revolutionary new plan, all this has changed. leading space exploration authority Robert Zubrin has crafted a daring new blueprint, Mars Direct, presented here with illustrations, photographs, and engaging anecdotes.The Case for Mars is not a vision for the far future or one that will cost us impossible billions. It explains step-by-step how we can use present-day technology to send humans to Mars within ten years; actually produce fuel and oxygen on the planet's surface with Martian natural resources; how we can build bases and settlements; and how we can one day "terraform" Mars--a process that can alter the atmosphere of planets and pave the way for sustainable life.

    He tells of the Nazi cult of the primeval German forest; the play of Christian and pagan myth in Bernini's Fountain of the Four Rivers; and the duel between a monumental sculptor and a feminist gadfly on the slopes of Mount Rushmore. The result is a triumphant work of history, naturalism, mythology, and art. "A work of great ambition and enormous intellectual scope...consistently provocative and revealing."--New York Times"Extraordinary...a summary cannot convey the riches of this book. It will absorb, instruct, and fascinate."--New York Review of Books

    Its author's engaging voice is one reason, and the compelling subjects he addresses is another; the nature of space and time, the role of God in creation, the history and future of the universe. But it is also true that in the years since its publication, readers have repeatedly told Professor Hawking of their great difficulty in understanding some of the book's most important concepts. This is the origin of and the reason for A Briefer History of Time: its author's wish to make its content more accessible to readers - as well as to bring it up-to-date with the latest scientific observations and findings.Although this book is literally somewhat "briefer", it actually expands on the great subjects of the original. Purely technical concepts, such as the mathematics of chaotic boundary conditions, are gone. Conversely, subjects of wide interest that were difficult to follow because they were interspersed throughout the book have now been given entire chapters of their own, including relativity, curved space, and quantum theory.This reorganization has allowed the authors to expand areas of special interest and recent progress, from the latest developments in string theory to exciting developments in the search for a complete unified theory of all the forces of physics. Like prior editions of the book - but even more so - A Briefer History of Time will guide nonscientists everywhere in the ongoing search for the tantalizing secrets at the heart of time and space. Thirty-seven full-color illustrations enhance the text and make A Briefer History of Time an exhilarating addition in its own right to the literature of science.

    Here Rowell assembled eighty of his finest images, along with the stories behind them—what he was after and how he achieved it.The photographs (and the details of their creation) are arranged in eight exhibits according to visual themes, reflecting Rowell’s fascination with the infinitely varying qualities of light found in mountain landscapes. He explains how film and the human eye see differently, how he selected and composed the content of his work, how he worked with optical phenomena and natural light, and how equipment and adventure interact in the field.The engaging text also recounts Rowell’s development as a photographer, his philosophy and techniques for creating “dynamic landscapes,” and his adventures in remote, dangerous, and beautiful places—from California’s Yosemite Valley to almost-inaccessible peaks in China.

    Line drawings highlight family characteristics, and plant entries discuss medicinal uses, edibility, toxicity, and look-alike plants. A standard reference at herbal and wilderness schools across the country, this resource is essential for herbalists, gardeners, and naturalists.

    Isolated and desolate, they were largely overlooked by early explorers until Charles Darwin arrived there in the 1830s. It was Darwin who recognized that Galapagos' isolation and desolation were advantages: the paucity of species and lack of outside influences made the workings of natural selection crystal clear. Since then, every important advance and controversy in evolutionary thinking has had its reflection on the Galapagos. In every sense-intellectually, institutionally, and culturally-the history of science on these islands is a history of the way evolutionary science was done for the past 150 years. Evolution's Workshop tells the story of Darwin's explorations there; the fabulous Gilded Age expeditions, run from rich men's gigantic yachts, that featured rough-and-ready science during the day and black-tie dinners every night; the struggle for control of research on the Galapagos; the current efforts by "creation scientists" to use the Galapagos to undercut evolutionary teaching; and many other compelling stories.

    Williams any rock used as building material can tell a fascinating story. All he has to do is look at building stone in any urban center to find a range of rocks equal to any assembled by plate tectonics. In Stories in Stone, he takes you on his explorations to find 3.5-billion-year-old rock that looks like swirled pink and black taffy, a gas station made of petrified wood, and a Florida fort that has withstood 300 years of attacks and hurricanes, despite being made of a stone that has the consistency of a granola bar.In Stories in Stone, Williams also weaves in the cultural history of stone. He shows why a white, fossil-rich limestone from Indiana became the only building stone to be used in all 50 states; how in 1825, the construction of the Bunker Hill Monument led to America's first commercial railroad; and why when the same kind of marble used by Michelangelo was used on a Chicago skyscraper it warped so much after 19 years that all 44,000 panels of the stone had to be replaced. A love letter to building stone, from New England brownstone and Morton Gneiss of Minnsota to the limestone of Salem, Indiana; from granite and travertine to Carrara marble, David Willilams brings to life the stones you will see in the structures of every city, large and small. After reading his book, you will forever look at stone buildings with new eyes.

    In this riveting examination of one of the last wild places on earth, Adam Weymouth canoes along the river's length, from Canada's Yukon Territory, through Alaska, to the Bering Sea. The result is a book that shows how even the most remote wilderness is affected by the same forces reshaping the rest of the planet.Every summer, hundreds of thousands of king salmon migrate the distance of the Yukon to their spawning grounds, where they breed and die, in what is the longest salmon run in the world. For the communities that live along the river, salmon was once the lifeblood of the economy and local culture. But climate change and a globalized economy have fundamentally altered the balance between man and nature; the health and numbers of king salmon are in question, as is the fate of the communities that depend on them.Traveling along the Yukon as the salmon migrate, a four-month journey through untrammeled landscape, Adam Weymouth traces the fundamental interconnectedness of people and fish through searing and unforgettable portraits of the individuals he encounters. He offers a powerful, nuanced glimpse into indigenous cultures, and into our ever-complicated relationship with the natural world. Weaving in the rich history of salmon across time as well as the science behind their mysterious life cycle, Kings of the Yukon is extraordinary adventure and nature writing at its most urgent and poetic.

    When Dan White and his girlfriend announced their intention to hike it, Dan's parents—among others—thought they were nuts. How could two people who'd never even shared an apartment together survive six months in the desert with little more than a two-person tent and some trail mix? But when these addled adventurers, dubbed "the Lois and Clark Expedition" by their benevolent trail-guru, set out for the American wilderness, the hardships of the trail—and one delicious-looking cactus—test the limits of love and sanity.

    The book argues for a realization of the finite nature of our resources, and the impact should we continue squandering them.

    This timely anthology calls on twenty eminent humanists and scientists to revitalize curiosity, observation, and transdisciplinary conversation about life on earth.As human-induced environmental change threatens multispecies livability, Arts of Living on a Damaged Planet puts forward a bold proposal: entangled histories, situated narratives, and thick descriptions offer urgent “arts of living.” Included are essays by scholars in anthropology, ecology, science studies, art, literature, and bioinformatics who posit critical and creative tools for collaborative survival in a more-than-human Anthropocene. The essays are organized around two key figures that also serve as the publication’s two openings: Ghosts, or landscapes haunted by the violences of modernity; and Monsters, or interspecies and intraspecies sociality. Ghosts and Monsters are tentacular, windy, and arboreal arts that invite readers to encounter ants, lichen, rocks, electrons, flying foxes, salmon, chestnut trees, mud volcanoes, border zones, graves, radioactive waste—in short, the wonders and terrors of an unintended epoch.Contributors: Karen Barad, U of California, Santa Cruz; Kate Brown, U of Maryland, Baltimore; Carla Freccero, U of California, Santa Cruz; Peter Funch, Aarhus U; Scott F.
