In the middle of the nineteenth century three diverse men discovered and named the Ice Ages. The heroes of the tale are an explorer-poet, Elisha Kent Kane (1820-1857), who spent two years trapped on Greenland's north coast, the renowned Swiss professor-author-lecturer, Louis Agassiz (1807-1873), and the Scottish geologist (and master politician) Charles Lyell (1797-1875). With their investigations, these adventurers changed our understanding of natural history and transformed Geology into the foundational science that supports biology, paleontology, oceanography, and, of course, glaciology.
A rich and exuberant group biography of the early geologists, the people who were first to excavate from the layers of the world its buried history.
The birth of geology was fostered initially by gentlemen whose wealth supported their interests, but in the nineteenth century, it was advanced by clergymen, academics, and women whose findings expanded the field. Reading the Rocks brings to life this eclectic cast of characters who brought passion, eccentricity, and towering intellect to the discovery of how Earth was formed.
Geology opened a window on the planet's ancient past. Contrary to the Book of Genesis, the rocks and fossils dug up showed that Earth was immeasurably old. Moreover, fossil evidence revealed progressive changes in life forms. It is no coincidence that Charles Darwin was a keen geologist.
Acclaimed biographer and science writer Brenda Maddox's story goes beyond William Smith, the father of English geology; Charles Lyell, the father of modern geology; and James Hutton, whose analysis of rock layers unveiled what is now called "deep time." She also explores the livesof fossil hunter Mary Anning, the Reverend William Buckland, Darwin, and many others--their triumphs and disappointments, and the theological, philosophical, and scientific debates their findings provoked. Reading the Rocks illustrates in absorbing and revelatory details how this group of early geologists changed irrevocably our understanding of the world.

Roy Chapman Andrews led "the most celebrated fossil-hunting expedition of the twentieth century", wrote New York Times science writer John Noble Wilford. Financed by Morgan, Rockefeller, and a host of other Wall Street titans, the Central Asiatic Expeditions (1922-1930) comprised the most ambitious scientific venture ever launched from the United States up to that time. Under the auspices of New York's American Museum of Natural History, Andrews conducted five expeditions to the last unchartered corner of the world: the Gobi Desert of Outer and Inner Mongolia. In Dragon Hunter, Charles Gallenkamp vividly recounts these tremendous discoveries and the unforgettable adventures that attended them. Filled with astonishing tales of Andrews and his team braving raging sandstorms and murderous bandits, enduring political intrigue and civil wars, and reveling in the fascinating world of Peking's foreign colony, Dragon Hunter also traces the religious controversy over evolution and the anti-imperialist conflicts between the United States and China that were sparked by Andrews's expeditions. Gallenkamp tells Andrews's incredible life story, from his beginnings as a floor sweeper at the American Museum of Natural History to his international fame as one of the century's most acclaimed explorers. The result is a thrilling page-turner-an epic search for dinosaurs and extinct mammals cloaked in a sweeping historical narrative.
"A cracking read, combining storytelling of the highest order with a trove of information. . . . What's remarkable is that it all fits together."--Wall Street Journal
"Successful science writing tells a complete story of the 'how'--the methodical marvel building up to the 'why'--and Randall does just that."--New York Times Book Review
" Randall] is a lucid explainer, street-wise and informal. Without jargon or mathematics, she steers us through centuries of sometimes tortuous astronomical history."--The Guardian
In Dark Matter and the Dinosaurs, Professor Lisa Randall, one of today's most influential theoretical physicists, takes readers on an intellectual adventure through the history of the cosmos, showing how events in the farthest reaches of the Universe created the conditions for life--and death--on our planet.
Sixty-six million years ago, an object the size of a city crashed into Earth, killing off the dinosaurs, along with three-quarters of the planet's species. Challenging the usual assumptions about the simple makeup of the unseen material that constitutes 85% of the matter in the Universe, Randall explains how a disk of dark matter in the Milky Way plane might have triggered the cataclysm.
But Dark Matter and the Dinosaurs does more than present a radical idea. With clarity and wit, it explains the nature of the Universe, dark matter, the Milky Way galaxy, comets, asteroids, and impacts. This breathtaking synthesis, illuminated by pop culture references and social and political viewpoints, reveals the deep relationships among the small and the large, the visible and the hidden, as well as the astonishing beauty of the connections that surround us. It's impossible to read this book and look at either the Earth or the sky again in the same way.
- A magnificent collection of 66 pieces of petrified wood mainly from the Western United States, specially photographed to show the artistic beauty hidden in Nature's masterpieces - All the images are unpublished and were specifically shot for this book - Authoritative text by the Curator of Minerals at the American Museum of Natural History This stunning book documents a collection of 66 extraordinary pieces of petrified wood, mainly from Western United States (Arizona, Oregon, Washington). Specially photographed they are shown in their entirety and in magnificent details. Petrified wood is formed from fallen trees that in the absence of oxygen and microbes, and with water containing minerals, through a replacement process called permineralization, slowly transform into visually spectacular fossils. But Nature often uses a paintbrush in its preservation magic, splashing the wooden canvas with an array of colors and hues before fixing it in a matrix of hard durable quartz, thereby creating splendid works of art. Petrified wood has been found throughout the world, but actual petrified forests are truly noteworthy in the United States, the most famous being the Chinle Formation forest of Arizona.
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 Bogot 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.
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.
