Available in PDF, EPUB and Kindle. Book excerpt: The possibility that the continents of the earth have undergone major changes in position during the earth's history has fascinated scholars for at least three hundred years. Recently, evidence from several scientific disciplines has shown that the possibility must be very seriously considered in any study of the surface features of the earth. The first part of this volume consists of papers given at a symposium on continental drift, held at the annual meeting of the Royal Society of Canada in Charlottetown in June 1964. They present the views of three geophysicists, a botanist, and an astronomer. In these papers, the present evidence for or against continental drift is reviewed and the authors in most cases draw their own conclusions. The reader will find that there is not unanimous agreement in favour of drift. Nearly all discussions of continental drift stress the possible separation of the Americas from Europe and Africa. Considerable work has been done on the tracing of structures, on each side of the Atlantic Ocean, which might once have been connected. Geologists and geophysicists working in the Arctic or on the eastern seaboard of Canada have an important contribution to make to this subject. The second part of this volume, therefore, consists of a group of papers, also presented at the Charlottetown meeting, which throw light on the complicated crustal structure of these regions. In any attempt to reconstruct North America as part of Europe the features described in these papers will have to be taken into account. Once again, the reader will find differences of opinion on the question of whether the evidence favours a separation of our continent from Europe. Indeed, it is because the theory of continental drift us so difficult to confirm without ambiguity by direct observation that it remains controversial but exciting.
Download or read book The Rejection of Continental Drift written by Naomi Oreskes and published by Oxford University Press. This book was released on 1999-04-01 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early twentieth century, American earth scientists were united in their opposition to the new--and highly radical--notion of continental drift, even going so far as to label the theory "unscientific." Some fifty years later, however, continental drift was heralded as a major scientific breakthrough and today it is accepted as scientific fact. Why did American geologists reject so adamantly an idea that is now considered a cornerstone of the discipline? And why were their European colleagues receptive to it so much earlier? This book, based on extensive archival research on three continents, provides important new answers while giving the first detailed account of the American geological community in the first half of the century. Challenging previous historical work on this episode, Naomi Oreskes shows that continental drift was not rejected for the lack of a causal mechanism, but because it seemed to conflict with the basic standards of practice in American geology. This account provides a compelling look at how scientific ideas are made and unmade.

Download or read book The Continental Drift Controversy Volume 2 Paleomagnetism and Confirmation of Drift written by Henry R. Frankel and published by Cambridge University Press. This book was released on 2012-04-26 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: The resolution of the sixty-year debate over continental drift, culminating in the triumph of plate tectonics, changed the very fabric of Earth science. This four-volume treatise on the continental drift controversy is the first complete history of the origin, debate and gradual acceptance of this revolutionary theory. Based on extensive interviews, archival papers and original works, Frankel weaves together the lives and work of the scientists involved, producing an accessible narrative for scientists and non-scientists alike. This second volume provides the first extensive account of the growing paleomagnetic case for continental drift in the 1950s and the development of apparent polar wander paths that showed how the continents had changed their positions relative to one another, more or less as Wegener had proposed. Paleomagnetism offered the first physical measure that continental drift had occurred and helped determine the changing latitudes of the continents through geologic time.
Download or read book Africa Forms the Key written by Suryakanthie Chetty and published by Springer Nature. This book was released on 2021-01-04 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the work of prominent South African geologist Alex Du Toit as a means of understanding the debate around continental drift both in segregation-era South Africa and internationally. It contextualises Du Toit’s work within a particularly formative period of South African science, from the paleoanthropological discoveries that sparked debates about the origins of humankind to Jan Smuts’ own theory of holism. Beyond South African scientific discoveries, the book sets Du Toit’s work against a backdrop of ideological struggles over space, both domestically in terms of segregation and nationalism, as well as internationally as South Africa sought to assert its position within the Commonwealth. These debates were embodied by Du Toit’s work on the theory of continental drift, which put Africa – and South Africa – at the centre geologically and geographically. The author also focuses on the divisions in geology caused by drift theory, tracing the vigorous intellectual debate and dissent indicative of the ideological milieu within which scientific thought is constructed. It traces the history of continental drift from its inception in the nineteenth century and later work of Alfred Wegener, which was both elaborated upon and substantiated by Du Toit. The study further focuses on Du Toit’s research on continental drift in South African and South America, and the geological, fossil and climatological evidence used to bolster this theory.
Download or read book New Earth Histories written by Alison Bashford and published by University of Chicago Press. This book was released on 2023-11-06 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: A kaleidoscopic rethinking of how we come to know the earth. This book brings the history of the geosciences and world cosmologies together, exploring many traditions, including Chinese, Pacific, Islamic, South and Southeast Asian conceptions of the earth’s origin and makeup. Together the chapters ask: How have different ideas about the sacred, animate, and earthly changed modern environmental sciences? How have different world traditions understood human and geological origins? How does the inclusion of multiple cosmologies change the meaning of the Anthropocene and the global climate crisis? By carefully examining these questions, New Earth Histories sets an ambitious agenda for how we think about the earth. The chapters consider debates about the age and structure of the earth, how humans and earth systems interact, and how empire has been conceived in multiple traditions. The methods the authors deploy are diverse—from cultural history and visual and material studies to ethnography, geography, and Indigenous studies—and the effect is to highlight how earth knowledge emerged from historically specific situations. New Earth Histories provides both a framework for studying science at a global scale and fascinating examples to educate as well as inspire future work. Essential reading for students and scholars of earth science history, environmental humanities, history of science and religion, and science and empire.
Download or read book The End written by Marq de Villiers and published by Macmillan. This book was released on 2010-03-30 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is the fate of the world as we know it? Tsunamis, earthquakes, volcanoes, hurricanes, pandemics, cosmic radiation, gamma bursts from space, colliding comets, and asteroids—these things used to worry us from time to time, but now they have become the background noise of our culture. Are natural calamities indeed more probable, and more frequent, than they were? Are things getting worse? Are the boundaries between natural and human-caused calamities blurring? Are we part of the problem? If so, what can we do about it? In The End, award-winning writer Marq de Villiers examines these questions at a time when there is an urgent need to understand the perils that confront us, to act in such a way as best we can for the inevitable disasters when they come. We can do nothing about some natural calamities, but about others we can do a great deal. De Villiers helps us understand which is which, and lays out some provocative ideas for mitigating the damage all such calamities can inflict on us and our world. The End is a brilliant and challenging look at what lies ahead, and at what we can do to influence our future.
