Rising from the Plains is John McPhee's third book on geology and geologists. Following Basin and Range and In Suspect Terrain, it continues to present a cross section of North America along the fortieth parallel--a series gathering under the overall title Annals of the Former World.
The bestselling author of The Professor and the Madman and The Map That Changed the World examines the enduring and world-changing effects of the catastrophic eruption off the coast of Java of the earth's most dangerous volcano -- Krakatoa.
The legendary annihilation in 1883 of the volcano-island of Krakatoa -- the name has since become a byword for a cataclysmic disaster -- was followed by an immense tsunami that killed nearly forty thousand people. Beyond the purely physical horrors of an event that has only very recently been properly understood, the eruption changed the world in more ways than could possibly be imagined. Dust swirled round die planet for years, causing temperatures to plummet and sunsets to turn vivid with lurid and unsettling displays of light. The effects of the immense waves were felt as far away as France. Barometers in Bogota and Washington, D.C., went haywire. Bodies were washed up in Zanzibar. The sound of the island's destruction was heard in Australia and India and on islands thousands of miles away. Most significant of all -- in view of today's new political climate -- the eruption helped to trigger in Java a wave of murderous anti-Western militancy among fundamentalist Muslims: one of the first outbreaks of Islamic-inspired killings anywhere.
Simon Winchester's long experience in the world wandering as well as his knowledge of history and geology give us an entirely new perspective on this fascinating and iconic event as he brings it telling back to life.
This is a photographic guide to 250 of the world's most essential minerals. From precious native elements such as silver, gold and copper to complex silicates such as vesuvianite, each one exemplifies the wonder of nature.
"Anything but frigid, this book is filled with fun facts about one of Minnesota's greatest--though possibly under-appreciated--natural treasures."
"Put your mittens on; you'll freeze to death " admonish the world's grandmothers as the temperature plummets. No doubt the Arctic explorers--today in their GORE-TEX, historically in their woolens--needed no such instruction. Icy climes bring with them the dangers of frostbite, but also the poetic beauty of glaciers and ice shelves, of ice palaces and aurora borealis. Karal Ann Marling explores these topics and more as she considers the history of "hard, cold water."
What better place to start than with dessert? The pleasure of ice cream on a hot day has been known since the sixteenth century, although it wasn't until a few hundred years later that reliable refrigeration made the treat readily available. Marling expands her icy explorations to the realm of fiction--the ice crossing in Uncle Tom's Cabin, the frozen wasteland of Frankenstein--and to the movies and Broadway. Cities vie for tourists by building shimmering ice palaces to celebrate winter; explorers compete to reach the poles, and not all live to tell the story. The study of ice by a true aficionado yields fascinating insights and may just inspire readers to embrace winter--or to make their way to the nearest ice cream shop.
At 5:36 p.m. on March 27, 1964, a magnitude 9.2. earthquake - the second most powerful in world history - struck the young state of Alaska. The violent shaking, followed by massive tsunamis, devastated the southern half of the state and killed more than 130 people. A day later, George Plafker, a geologist with the U.S. Geological Survey, arrived to investigate. His fascinating scientific detective work in the months that followed helped confirm the then-controversial theory of plate tectonics. In a compelling tale about the almost unimaginable brute force of nature, New York Times science journalist Henry Fountain combines history and science to bring the quake and its aftermath to life in vivid detail. With deep, on-the-ground reporting from Alaska, often in the company of George Plafker, Fountain shows how the earthquake left its mark on the land and its people -- and on science.
It is a prominent geological feature that is almost impossible to see unless you know where to look. Hundreds of thousands of people drive across it every day. The San Andreas Fault is everywhere, and primed for a colossal quake. For decades, scientists have warned that such a sudden shifting of the Earth's crust is inevitable. In fact, it is a geologic necessity.
The San Andreas fault runs almost the entire length of California, from the redwood forest to the east edge of the Salton Sea. Along the way, it passes through two of the largest urban areas of the country--San Francisco and Los Angeles. Dozens of major highways and interstates cross it. Scores of housing developments have been planted over it. The words "San Andreas" are so familiar today that they have become synonymous with earthquake.
Yet, few people understand the San Andreas or the network of subsidiary faults it has spawned. Some run through Hollywood, others through Beverly Hills and Santa Monica. The Hayward fault slices the football stadium at the University of California in half. Even among scientists, few appreciate that the San Andreas fault is a transient, evolving system that, as seen today, is younger than the Grand Canyon and key to our understanding of earthquakes worldwide.
Until a few decades ago, the ocean depths were almost as mysterious and inaccessible as outer space. Oceans cover two-thirds of the earth's surface with an average depth of more than two miles--yet humans had never ventured more than a few hundred feet below the waves. One of the great scientific and archaeological feats of our time has been finally to cast light on the "eternal darkness" of the deep sea. This is the story of that achievement, told by the man who has done more than any other to make it possible: Robert Ballard.Ballard discovered the wreck of the Titanic. He led the teams that discovered hydrothermal vents and "black smokers"--cracks in the ocean floor where springs of superheated water support some of the strangest life-forms on the planet. He was a diver on the team that explored the mid-Atlantic ridge for the first time, confirming the theory of plate tectonics. Today, using a nuclear submarine from the U.S. Navy, he's exploring the ancient trade routes of the Mediterranean and the Black Sea for the remains of historic vessels and their cargo. In this book, he combines science, history, spectacular illustrations, and first-hand stories from his own expeditions in a uniquely personal account of how twentieth-century explorers have pushed back the frontiers of technology to take us into the midst of a world we could once only guess at. Ballard begins in 1930 with William Beebe and Otis Barton, pioneers of the ocean depths who made the world's first deep-sea dives in a cramped steel sphere. He introduces us to Auguste and Jacques Piccard, whose "Bathyscaph"descended in 1960 to the lowest point on the ocean floor. He reviews the celebrated advances made by Jacques Cousteau. He describes his own major discoveries--from sea-floor spreading to black smokers--as well as his technical breakthroughs, including the development of remote-operated underwater vehicles and the revolutionary search techniques that led to the discovery and exploration of the Titanic, the Nazi battleship Bismarck, ancient trading vessels, and other great ships. Readers will come away with a richer understanding of history, earth science, biology, and marine technology--and a new appreciation for the remarkable men and women who have explored some of the most remote and fascinating places on the planet.
Why an awareness of Earth's temporal rhythms is critical to our planetary survivalFew of us have any conception of the enormous timescales in our planet's long history, and this narrow perspective underlies many of the environmental problems we are creating for ourselves. The passage of nine days, which is how long a drop of water typically stays in Earth's atmosphere, is something we can easily grasp. But spans of hundreds of years--the time a molecule of carbon dioxide resides in the atmosphere--approach the limits of our comprehension. Our everyday lives are shaped by processes that vastly predate us, and our habits will in turn have consequences that will outlast us by generations. Timefulness reveals how knowing the rhythms of Earth's deep past and conceiving of time as a geologist does can give us the perspective we need for a more sustainable future. Marcia Bjornerud shows how geologists chart the planet's past, explaining how we can determine the pace of solid Earth processes such as mountain building and erosion and comparing them with the more unstable rhythms of the oceans and atmosphere. These overlapping rates of change in the Earth system--some fast, some slow--demand a poly-temporal worldview, one that Bjornerud calls "timefulness." She explains why timefulness is vital in the Anthropocene, this human epoch of accelerating planetary change, and proposes sensible solutions for building a more time-literate society. This compelling book presents a new way of thinking about our place in time, enabling us to make decisions on multigenerational timescales. The lifespan of Earth may seem unfathomable compared to the brevity of human existence, but this view of time denies our deep roots in Earth's history--and the magnitude of our effects on the planet.
When the ancient Greeks saw deposits of giant fossils, they knew they had discovered the battle fields where the gods had vanquished the Titans. When the Chinese discovered buried ivory, they knew they had found dragons' teeth. But as the Age of Reason dawned, monsters and giants gave way to the scientific method. Yet the mystery of these mighty bones remained. How did Enlightenment thinkers overcome centuries of myth and misunderstanding to reconstruct an unknown animal?
The journey to unravel that puzzle begins in the 1690s with the arrival of new type of ivory on the European market bearing the exotic name "mammoth." It ends during the Napoleonic Wars with the first recovery of a frozen mammoth. The path to figuring out the mammoth was traveled by merchants, diplomats, missionaries, cranky doctors, collectors of natural wonders, Swedish POWs, Peter the Great, Ben Franklin, the inventor of hot chocolate, and even one pirate.
McKay brings together dozens of original documents and illustrations, some ignored for centuries, to show how this odd assortment of characters solved the mystery of the mammoth and, in doing so, created the science of paleontology.
