A historical account of the triumph of the global theory of plate tectonics and its implications for the "modern revolution in geology" of the 1960s and 1970s after fifty years of controversy and competition.
A source of profound influence and controversy, this landmark 1915 work explains various phenomena of historical geology, geomorphy, paleontology, paleoclimatology, and similar areas in terms of continental drift. 64 illustrations. 1966 edition.
From December 1811 to February 1812, massive earthquakes shook the middle Mississippi Valley, collapsing homes, snapping large trees midtrunk, and briefly but dramatically reversing the flow of the continent’s mightiest river. For decades, people puzzled over the causes of the quakes, but by the time the nation began to recover from the Civil War, the New Madrid earthquakes had been essentially forgotten. In The Lost History of the New Madrid Earthquakes, Conevery Bolton Valencius remembers this major environmental disaster, demonstrating how events that have been long forgotten, even denied and ridiculed as tall tales, were in fact enormously important at the time of their occurrence, and continue to affect us today. Valencius weaves together scientific and historical evidence to demonstrate the vast role the New Madrid earthquakes played in the United States in the early nineteenth century, shaping the settlement patterns of early western Cherokees and other Indians, heightening the credibility of Tecumseh and Tenskwatawa for their Indian League in the War of 1812, giving force to frontier religious revival, and spreading scientific inquiry. Moving into the present, Valencius explores the intertwined reasons—environmental, scientific, social, and economic—why something as consequential as major earthquakes can be lost from public knowledge, offering a cautionary tale in a world struggling to respond to global climate change amid widespread willful denial. Engagingly written and ambitiously researched—both in the scientific literature and the writings of the time—The Lost History of the New Madrid Earthquakes will be an important resource in environmental history, geology, and seismology, as well as history of science and medicine and early American and Native American history.
Explores the Supercontinent Cycle from the earliest recorded time to the geological discoveries of today including the drifting of the continents and the evolution of dinosaurs.
Why did American geologists reject the notion of continental drift, first posed in 1915? And why did British scientists view the theory as a pleasing confirmation? This text, based on archival resources, provides answers to these questions.
Alfred Lothar Wegener (1880-1930) was a German geophysicist and meteorologist. His research focused mainly on meteorology and polar research, however he is most remembered as the originator of the theory of continental drift, i.e. that the continents are slowly drifting around the Earth. His hypothesis was controversial and widely rejected by mainstream geology until the 1950s, when novel discoveries such as palaeomagnetism provided strong support for continental drift, which is the basis for today's model of plate tectonics. Third edition, originally published in 1924.
Describes the expansion of the land-based paleomagnetic case for drifting continents and recounts the golden age of marine geoscience.
The definitive account of the early debate over Wegener's theory of continental drift, based on extensive interviews and archival material.
The planet as seen by its inhabitants In two millenia, our knowledge of the planet and its natural laws and forces has undergone remarkable changes--from the religious belief of earth as the center of the universe to the modern astronomers' view that it is a mere speck in the cosmos. Now a first-of-its-kind reference work charts this remarkable intellectual progression in our evolving perception of the earth by surveying the history of geology, geography, geophysics, oceanography, meteorology, space science, and many other fields. Covers human understanding of the Earth in various times and cultures The Encyclopedia traces our understanding of the earth and its functioning throughout history, summarizing historical explanations of earthly occurrences, including explanations with no scientific basis. It presents the latest facts and theories, explains how our understanding of the earth has evolved, and shows why many outrageous and fanciful earlier ideas were accepted in their time. The coverage explores the physical phenomena that inform our knowledge, starting at the earth's core and extending outward through the mantle, crust, oceans, and atmosphere to the magnetosphere and beyond. Charts the evolution of our perceptions The primary focus of the Encyclopedia is the history of the study of the earth. It also discusses the institutions that advanced and shaped science and probes the interplay between science, practical applications, and social and political forces. The result is a unified historical overview of the earth across a wide canvas of time and place, from antiquity to the space age. Its wide-ranging articles summarize subjects as diverse as geography and imperialism, environmentalism, computers and meteorology, ozone formation theories since 1800, scientific rocketry, the Scopes trial, and much more. Special Features Shows how diverse disciplines, from geology to space science, fit together in a coherent view of the earth * Explains earlier ideas and theories in the context of the beliefs and scientific knowledge of their time * Spotlights important institutions that have shaped the history of science * Explores relationships between science, practical applications, and sociopolitical concerns * Provides a subject index and an index of scientists with birth/death dates
