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.
En Catastrofobia, Barbara Hand Clow, autora de libros de gran xito, examina legendarios cataclismos y muestra c mo, contrario a muchas profec as de fatalidades, estamos en la c spide de una era de incre ble crecimiento creativo. El reciente descubrimiento de los vestigios de arcaicos pueblos enterrados bajo el Mar Negro, es la m s ltima instancia de evidencia de que muchas "m ticas" cat strofes de la historia--la ca da de la Atl ntida, el Diluvio B blico--fueron eventos reales. Barbara Hand Clow muestra que una serie de desastres catacl smicos, causados por una masiva alteraci n en la corteza terrestre de hace 11,500 a os, estremeci al mundo y dej la psique humana colectiva profundamente cicatrizada. Somos una especie herida y este miedo sin procesar, que pas de generaci n, es responsable de nuestras constantes expectativas del apocalipsis, del Y2K al famoso final del calendario Maya en el 2012.Catastrofobia revela como las insidiosas fuerzas globales han usado estos miedos colectivos para controlar a la humanidad por miles de a os. Pero estamos a la mitad de un tremendo cambio en el ciclo precesional de la Tierra de 26,000 a os y existe toda la indicaci n de que los cambios en la consciencia durante los ltimos treinta a os son los comienzos de una colectiva curaci n de estos profundos miedos, presagiando que un tiempo de extraordinaria actividad creativa est al alcance de la mano.
At various times in a span of fifteen years, John McPhee made geological field surveys in the company of Eldridge Moores, a tectonicist at the University of California at Davis. The result of these trips is Assembling California, a cross-section in human and geologic time, from Donner Pass in the Sierra Nevada through the golden foothills of the Mother Lode and across the Great Central Valley to the wine country of the Coast Ranges, the rock of San Francisco, and the San Andreas family of faults. The two disparate time scales occasionally intersect--in the gold disruptions of the nineteenth century no less than in the earthquakes of the twentieth--and always with relevance to a newly understood geologic history in which half a dozen large and separate pieces of country are seen to have drifted in from far and near to coalesce as California. McPhee and Moores also journeyed to remote mountains of Arizona and to Cyprus and northern Greece, where rock of the deep-ocean floor has been transported into continental settings, as it has in California. Global in scope and a delight to read, Assembling California is a sweeping narrative of maps in motion, of evolving and dissolving lands.
From the author of the bestselling The Professor and the Madman comes the fascinating story of William Smith, the orphaned son of an English country blacksmith, who became obsessed with creating the world's first geological map and ultimately became the father of modern geology.In 1793 William Smith, a canal digger, made a startling discovery that was to turn the fledgling science of the history of the earth -- and a central plank of established Christian religion -- on its head. He noticed that the rocks he was excavating were arranged in layers; more important, he could see quite clearly that the fossils found in one layer were very different from those found in another. And out of that realization came an epiphany: that by following the fossils, one could trace layers of rocks as they dipped and rose and fell -- clear across England and, indeed, clear across the world. Determined to publish his profoundly important discovery by creating a map that would display the hidden underside of England, he spent twenty years traveling the length and breadth of the kingdom by stagecoach and on foot, studying rock outcrops and fossils, piecing together the image of this unseen universe.In 1815 he published his epochal and remarkably beautiful hand-painted map, more than eight feet tall and six feet wide. But four years after its triumphant publication, and with his young wife going steadily mad to the point of nymphomania, Smith ended up in debtors' prison, a victim of plagiarism, swindled out of his recognition and his profits. He left London for the north of England and remained homeless for ten long years as he searched for work. It wasn't until 1831, when his employer, a sympathetic nobleman, brought him into contact with the Geological Society of London -- which had earlier denied him a fellowship -- that at last this quiet genius was showered with the honors long overdue him. He was summoned south to receive the society's highest award, and King William IV offered him a lifetime pension.The Map That Changed the World is, at its foundation, a very human tale of endurance and achievement, of one man's dedication in the face of ruin and homelessness. The world's coal and oil industry, its gold mining, its highway systems, and its railroad routes were all derived entirely from the creation of Smith's first map.; and with a keen eye and thoughtful detail, Simon Winchester unfolds the poignant sacrifice behind this world-changing discovery.
Environmental historian Philip L. Fradkin offers a vivid history of earthquakes and an eloquent guide to the San Andreas Fault, the seismic scar that bisects the Golden State's spectacular scenery. The author includes dramatic stories of legendary earthquakes elsewhere: in New York, New England, the central Mississippi River Valley, Europe, and the Far East. Combining human and natural dramas, he places the reader at the epicenter of the most invisible, unpredictable, and feared of the earth's violent phenomena. On the eve of the millennium, as cyberspace crackles with apocalyptic visions, Fradkin reaches beyond the earthshaking moment to examine the mythology, culture, social implications, politics, and science of earthquakes.
Simon Winchester, New York Times bestselling author of The Professor and the Madman, examines the legendary annihilation in 1883 of the volcano-island of Krakatoa, which was followed by an immense tsunami that killed nearly forty thousand people. 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. Krakatoa gives us an entirely new perspective on this fascinating and iconic event.
A guide to how water can prevent and treat disease as well as rejuvenate the body and mind- Shows the role water deficiency plays in a large number of diseases and other health disorders - Explains how to determine the quality and quantity of water that is best for you and the time during the day it is best to drink - Includes 10 water cures for profound physical rehydration, toxin removal, and remineralization Drinking sufficient quantities of water is a necessity for optimal physical functioning, but it can also play a major role in the prevention and treatment of many diseases. Chronic fatigue, depression, eczema, rheumatism, gastric disorders, high or low blood pressure, high cholesterol, obesity, and urinary infections are but a few of the many disorders that can result from not drinking enough water--and which can be treated by raising our intake of this vital liquid. The physical assaults that our bodies endure from pollution, stress, overly rich and processed foods (often containing too much salt), and alcohol and tobacco have dramatically increased our daily need for water over what our ancestors required. Christopher Vasey explains not only why water is so essential to our health but also what quantities we should drink and when. He also discusses the qualities of different types of water and demonstrates which will best address certain conditions. In addition, he provides 10 water cures that will rehydrate the deepest levels of the body, remove toxins, and restore vital minerals.
