Even as it guides us across town, GPS helps land planes, route mobile calls, anticipate earthquakes, predict weather, locate oil deposits, measure neutrinos, grow our food, and regulate global finance. It is as ubiquitous and essential as another Cold War technology, the Internet. In Pinpoint, Greg Milner takes us on a fascinating tour of a hidden system that touches almost every aspect of our modern life.While GPS has brought us breathtakingly accurate information about our planetary environment and physical space, it has also created new forms of human behavior. We have let it saturate the world’s systems so completely and so quickly that we are just beginning to confront the possible consequences. A single GPS timing flaw, whether accidental or malicious, could bring down the electrical grid, hijack drones, or halt the world financial system. The use, and potential misuse, of GPS data by government and corporations raise disturbing questions about ethics and privacy. GPS may be altering the nature of human cognition—possibly even rearranging the gray matter in our heads.Pinpoint tells the sweeping story of GPS from its conceptual origins as a bomb guidance system to its presence in almost everything we do. Milner examines the different ways humans have understood physical space, delves into the neuroscience of cognitive maps, and questions GPS’s double-edged effect on our culture. A fascinating and original story of the scientific urge toward precision, Pinpoint offers startling insight into how humans understand their place in the world.

    A desert, by definition, lacks it, but when water does come, it comes in torrential, sometimes devastating abundance. Childs, a thirtysomething desert rat with a vast knowledge of the Southwest's remote corners, knows this fact well. "Most rain falling anywhere but the desert comes slow enough that it is swallowed by the soil without comment," he observes. "Desert rains, powerful and sporadic, tend to hit the ground, gather into floods, and are gone before the water can sink five inches into the ground."The travels that Childs recounts in this vivid narrative take him from places sometimes parched, sometimes swimming, from the depths of the Grand Canyon to the dry limestone tanks of the lava-strewn Sonoran Desert. As he travels, Childs gives a close reading of the desert landscape ("the moral," he writes at one point, "is that if you know the land and its maps, you might live"), observing the rocks, plants, animals, and people that call it home. Some of his adventures will remind readers of Edward Abbey's Desert Solitaire—save that Childs writes without Abbey's bluster, and with a measured lyricism that well suits the achingly lovely back canyons and cactus forests of the Southwest. By turns travelogue, ecological treatise, and meditative essay, Childs's book will speak to anyone who has spent time under desert skies, wondering when the next drop of rain might fall.

    First, geologists realized that the continents themselves were drifting across the surface of the globe and that oceans were being created and destroyed. Secondly, pictures of the entire planet were returned from space. Suddenly, the Earth began to be viewed as a single entity; a dynamic, interacting whole, controlled by complex processes we scarcely understood. This Introduction explores emerging geological research and explains how new advances in the understanding of plate tectonics, seismology, and satellite imagery have enabled us to begin to see the Earth as it actually is: dynamic and ever changing.

    Tucked in a life preserver, she washed onto a sandbar as the craft sank from view. That first baptism began a lifelong relationship with a stunning and powerful river that almost nobody knows.The Altamaha rises dark and mysterious in southeast Georgia. It is deep and wide bordered by swamps. Its corridor contains an extraordinary biodi­versity, including many rare and endangered species, which led the Nature Conservancy to designate it as one of the world’s last great places.The Altamaha is Ray’s river, and from childhood she dreamed of paddling its entire length to where it empties into the sea. Drifting into Darien begins with an account of finally making that journey, turning to medita­tions on the many ways we accept a world that contains both good and evil. With praise, biting satire, and hope, Ray contemplates transformation and attempts with every page to settle peacefully into the now.Though commemorating a history that includes logging, Ray celebrates “a culture that sprang from the flatwoods, which required a judicious use of nature.” She looks in vain for an ivorybill woodpecker but is equally eager to see any of the imperiled species found in the river basin: spiny mussel, American oystercatcher, Radford’s mint, Alabama milkvine. The book explores both the need and the possibilities for conservation of the river and the surrounding forests and wetlands. As in her groundbreaking Ecology of a Cracker Childhood, Ray writes an account of her beloved river that is both social history and natural history, understanding the two as inseparable, particularly in the rural corner of Georgia that she knows best. Ray goes looking for wisdom and finds a river.

    His father, a Depression migrant trained as a welder, helped build dams and later worked at the secret Hanford plutonium plant. Now he and his neighbors, once considered patriots, stand accused of killing the river.As Blaine Harden traveled the Columbia-by barge, car, and sometimes on foot-his past seemed both foreign and familiar. A personal narrative of rediscovery joined a narrative of exploitation: of Native Americans, of endangered salmon, of nuclear waste, and of a once-wild river now tamed to puddled remains.Part history, part memoir, part lament, "this is a brave and precise book," according to the New York Times Book Review. "It must not have been easy for Blaine Harden to find himself turning his journalistic weapons against his own heritage, but he has done the conscience of his homeland a great service."

    Almost five hundred years later, the revolution he set in motion is nearly complete. Just as earth is not the center of things, the life on it, it appears, is not unique to the planet. Or is it? The Life of Super-Earths is a breathtaking tour of current efforts to answer the age-old question: Are we alone in the universe? Astronomer Dimitar Sasselov, the founding director of Harvard University’s Origins of Life Initiative, takes us on a fast-paced hunt for habitable planets and alien life forms. He shows how the search for “super-Earths”—rocky planets like our own that orbit other stars—may provide the key to answering essential questions about the origins of life here and elsewhere. That is, if we don’t find the answers to those questions here first. As Sasselov and other astronomers have uncovered planets with mixes of elements different from our own, chemists have begun working out the heretofore unseen biochemistries that those planets could support. That knowledge is feeding directly into synthetic biology—the effort to build wholly novel forms of life—making it likely that we will first discover truly “alien” life forms in an earthly lab, rather than on a remote planet thousands of light years away. Sasselov tells the gripping story of a moment of unprecedented potential—a convergence of pioneering efforts in astronomy and biology to peer into the unknown. The Life of Super-Earths offers nothing short of a transformation in our understanding of life and its place in the cosmos.

    Reisner believes that the success of this last great desert civilization hinges on California's denial of its own inescapable fate: Both the Los Angeles and San Francisco Bay areas sit astride two of the most violently seismic zones on the planet. The earthquakes that have already rocked California were, according to Reisner, a mere prologue to a future cataclysm that will result in immense destruction. Concluding with a hypothetical but chillingly realistic description of what such a disaster would look like, A Dangerous Place mixes science, history, and cultural commentary in a haunting work of profound importance.
