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.

This collection of essays examines the ways in which disputes and controversies about the application of scientific knowledge are resolved. Four concrete examples of public controversy are considered in detail: the efficacy of Laetrile, the classification of homosexuality as a disease, the setting of safety standards in the workplace, and the utility of nuclear energy as a source of power. The essays in this volume show that debates about these cases are not confined to matters of empirical fact. Rather, as is seen with most scientific and technical controversies, they focus on and are structured by complex ethical, economic, and political interests. Drs. Engelhardt and Caplan have brought together a distinguished group of scholars from the sciences and humanities, who sketch a theory of scientific controversy and attempt to provide recommendations about the ways in which both scientists and the public ought to seek more informed resolutions of highly contentious issues in science and technology. Scientific Controversies is offered as a contribution to the better understanding of the roles of both science and nonscientific interests in disputes and controversies pertaining to science and technology.

Provides a comprehensive introduction to the human, social and economic aspects of science and technology. It is broad, interdisciplinary and international, with a focus on Australia. The authors present complex issues in an accessible and engaging form. Invaluable for both students and teachers.

Over the course of the twentieth century, scientists came to accept four counterintuitive yet fundamental facts about the Earth: deep time, continental drift, meteorite impact, and global warming. When first suggested, each proposition violated scientific orthodoxy and was quickly denounced as scientific—and sometimes religious—heresy. Nevertheless, after decades of rejection, scientists came to accept each theory. The stories behind these four discoveries reflect more than the fascinating push and pull of scientific work. They reveal the provocative nature of science and how it raises profound and sometimes uncomfortable truths as it advances. For example, counter to common sense, the Earth and the solar system are older than all of human existence; the interactions among the moving plates and the continents they carry account for nearly all of the Earth's surface features; and nearly every important feature of our solar system results from the chance collision of objects in space. Most surprising of all, we humans have altered the climate of an entire planet and now threaten the future of civilization. This absorbing scientific history is the only book to describe the evolution of these four ideas from heresy to truth, showing how science works in practice and how it inevitably corrects the mistakes of its practitioners. Scientists can be wrong, but they do not stay wrong. In the process, astonishing ideas are born, tested, and over time take root.

Plate tectonics is a revolutionary theory on a par with modern genetics. Yet, apart from the frequent use of clichés such as 'tectonic shift' by economists, journalists, and politicians, the science itself is rarely mentioned and poorly understood. This book explains modern plate tectonics in a non-technical manner, showing not only how it accounts for phenomena such as great earthquakes, tsunamis, and volcanic eruptions, but also how it controls conditions at the Earth's surface, including global geography and climate. The book presents the advances that have been made since the establishment of plate tectonics in the 1960s, highlighting, on the 50th anniversary of the theory, the contributions of a small number of scientists who have never been widely recognized for their discoveries. Beginning with the publication of a short article in Nature by Vine and Matthews, the book traces the development of plate tectonics through two generations of the theory. First generation plate tectonics covers the exciting scientific revolution of the 1960s and 1970s, its heroes and its villains. The second generation includes the rapid expansions in sonar, satellite, and seismic technologies during the 1980s and 1990s that provided a truly global view of the plates and their motions, and an appreciation of the role of the plates within the Earth 'system'. The final chapter bring us to the cutting edge of the science, and the latest results from studies using technologies such as seismic tomography and high-pressure mineral physics to probe the deep interior. Ultimately, the book leads to the startling conclusion that, without plate tectonics, the Earth would be as lifeless as Venus.

A masterful biography of Alfred Wegener (1880–1930), the German scientist who discovered continental drift. Winner of the CHOICE Outstanding Academic Title of the Choice ACRL Alfred Wegener aimed to create a revolution in science which would rank with those of Nicolaus Copernicus and Charles Darwin. After completing his doctoral studies in astronomy at the University of Berlin, Wegener found himself drawn not to observatory science but to rugged fieldwork, which allowed him to cross into a variety of disciplines. The author of the theory of continental drift—the direct ancestor of the modern theory of plate tectonics and one of the key scientific concepts of the past century—Wegener also made major contributions to geology, geophysics, astronomy, geodesy, atmospheric physics, meteorology, and glaciology. Remarkably, he completed this pathbreaking work while grappling variously with financial difficulty, war, economic depression, scientific isolation, illness, and injury. He ultimately died of overexertion on a journey to probe the Greenland icecap and calculate its rate of drift. This landmark biography—the only complete account of the scientist’s fascinating life and work—is the culmination of more than twenty years of intensive research. In Alfred Wegener, Mott T. Greene places Wegener’s upbringing and theoretical advances in earth science in the context of his brilliantly eclectic career, bringing Wegener to life by analyzing his published scientific work, delving into all of his surviving letters and journals, and tracing both his passionate commitment to science and his thrilling experiences as a polar explorer, a military officer during World War I, and a world-record–setting balloonist. In the course of writing this book, Greene traveled to every place that Alfred Wegener lived and worked—to Berlin, rural Brandenburg, Marburg, Hamburg, and Heidelberg in Germany; to Innsbruck and Graz in Austria; and onto the Greenland icecap. He also pored over archives in Copenhagen, Munich, Marburg, Graz, and Bremerhaven, where the majority of Wegener’s surviving papers are found. Written with great immediacy and descriptive power, Alfred Wegener is a powerful portrait of the scientist who pioneered the modern concept of unified Earth science. The book should be of interest not only to earth scientists, students of polar travel and exploration, and historians but to all readers who are fascinated by the great minds of science.

Evidence and logic are lacking in many areas of public debate today on hot-button issues ranging from dietary fat to vaccination. In Science Under Attack, Dr. Alexander shows how science is being abused, sidelined or ignored, making it difficult or impossible for the public to form a reasoned opinion about important issues. Readers will learn why science is becoming more corrupt, and also how it is being abused for political and economic gain, support of activism, or the propping up of religious beliefs. To illustrate how science is being ignored and abused, the author examines six different issues and the way they are currently discussed: evolution, dietary fat, climate change, vaccination, GMO crops and continental drift. In his research, he has gone back to the original source wherever possible rather than quoting second-hand sources, adding a degree of accuracy and nuance often missing. The controversial assertion that science does not support the conventional wisdom on climate change should be of particular interest. Alexander shows that the scientific evidence for a substantial human contribution to climate change is actually flimsy, and he demonstrates the fallacy of comparing the strong link between smoking and lung cancer to the much weaker connection between human activity and global warming.

The main focus of this book is on the interconnection of two unorthodox scientific ideas, the varying-gravity hypothesis and the expanding-earth hypothesis. As such, it provides a fascinating insight into a nearly forgotten chapter in both the history of cosmology and the history of the earth sciences. The hypothesis that the force of gravity decreases over cosmic time was first proposed by Paul Dirac in 1937. In this book the author examines in detail the historical development of Dirac’s hypothesis and its consequences for the structure and history of the earth, the most important of which was that the earth must have been smaller in the past.

Is science getting at the truth? The sceptics - those who spread doubt about science - often employ a simple argument: scientists were 'sure' in the past, and then they ended up being wrong. Through a combination of historical investigation and philosophical-sociological analysis, Identifying Future-Proof Science defends science against this potentially dangerous scepticism. Indeed, we can confidently identify many scientific claims that are future-proof: they will last forever, so long as science continues. How do we identify future-proof claims? This appears to be a new question for science scholars, and not an unimportant one. Peter Vickers argues that the best way to identify future-proof science is to avoid any attempt to analyse the relevant first-order scientific evidence, instead focusing purely on second-order evidence. Specifically, a scientific claim is future-proof when the relevant scientific community is large, international, and diverse, and at least 95% of that community would describe the claim as a 'scientific fact'. In the entire history of science, no claim meeting these criteria has ever been overturned, despite enormous opportunity.
