The Origin of Chondrules and Chondrites

The Origin of Chondrules and Chondrites

Derek W. G. Sears

Cambridge University Press
2004
sidottu
Chondrites are the largest group of meteorites. They can provide unique insights into the origins and early evolution of our solar system, and even into the relationships between our solar system and other stars in the vicinity of our Sun. The largest structural components of most chondrites are the glass-bearing chondrules, and there are numerous theories for their origin. This clear and systematic text summarises the ideas surrounding the origin and history of chondrules and chondrites, drawing on research from the various scientific disciplines involved. With citations to every published paper on the topic, it forms a comprehensive bibliography of the latest research, and extensive illustrations provide a clear visual representation of the scientific theories. This text will be a valuable reference for graduate students and researchers in planetary science, geology and astronomy.

Astronomer Gerard P. Kuiper ignored the traditional boundaries of his subject. Using telescopes and the laboratory, he made the solar system a familiar, intriguing place. “It is not astronomy,” complained his colleagues, and they were right. Kuiper had created a new discipline we now call planetary science. Kuiper was an acclaimed astronomer of binary stars and white dwarfs when he accidentally discovered that Titan, the massive moon of Saturn, had an atmosphere. This turned our understanding of planetary atmospheres on its head, and it set Kuiper on a path of staggering discoveries: Pluto was not a planet, planets around other stars were common, some asteroids were primary while some were just fragments of bigger asteroids, some moons were primary and some were captured asteroids or comets, the atmosphere of Mars was carbon dioxide, and there were two new moons in the sky, one orbiting Uranus and one orbiting Neptune.He produced a monumental photographic atlas of the Moon at a time when men were landing on our nearest neighbor, and he played an important part in that effort. He also created some of the world's major observatories in Hawai‘i and Chile. However, most remarkable was that the keys to his success sprang from his wartime activities, which led him to new techniques. This would change everything.Sears shows a brilliant but at times unpopular man who attracted as much dislike as acclaim. This in-depth history includes some of the twentieth century's most intriguing scientists, from Harold Urey to Carl Sagan, who worked with—and sometimes against—the father of modern planetary science. Now, as NASA and other space agencies explore the solar system, they take with them many of the ideas and concepts first described by Gerard P. Kuiper.

Shedding Light is the result of 30 years of research by a team of about fourteen scientists. This book consists of an introduction to meteorites and Moon rocks for the lay-person and 60 glorious color plates of meteorites and Moon rocks under the luminescence microscope. Nothing like it has been published before. These images are beautiful to look at, but they also tell a tale of these extraordinary rocks from the primitive solar system on the eve of its formation 4.5 billion years ago to Moon rocks returned by the Apollo astronauts as part of the greatest voyage of exploration undertaken by humanity.

Elliptic Operators and Lie Groups

Elliptic Operators and Lie Groups

Derek W. Robinson

Clarendon Press
1991
sidottu
Elliptic operators arise naturally in several different mathematical settings, notably in the representation theory of Lie groups, the study of evolution equations, and the examination of Riemannian manifolds. This book develops the basic theory of elliptic operators on Lie groups and thereby extends the conventional theory of parabolic evolution equations to a natural non-commutative context. In order to achieve this goal, the author presents a synthesis of ideas from partial differential equations, harmonic analysis, functional analysis, and the theory of Lie groups. He begins by discussing the abstract theory of general operators with complex coefficients before concentrating on the central case of second-order operators with real coefficients. A full discussion of second-order subellilptic operators is also given. Prerequisites are a familiarity with basic semigroup theory, the elementary theory of Lie groups, and a firm grounding in functional analysis as might be gained from the first year of a graduate course.

In 1931, the United States and France embarked on a broadcasting partnership built around radio. Over time, the transatlantic sonic alliance came to personify and to shape American-French relations in an era of increased global media production and distribution. Drawing on a broad range of American and French archives, Derek Vaillant joins textual and aural materials with original data analytics and maps to illuminate U.S.-French broadcasting's political and cultural development. Vaillant focuses on the period from 1931 until France dismantled its state media system in 1974. His analysis examines mobile actors, circulating programs, and shifting institutions that shaped international radio's use in times of war and peace. He explores the extraordinary achievements, the miscommunications and failures, and the limits of cooperation between America and France as they shaped a new media environment. Throughout, Vaillant explains how radio's power as an instantaneous mass communications tool produced, legitimized, and circulated various notions of states, cultures, ideologies, and peoples as superior or inferior. A first comparative history of its subject, Across the Waves provocatively examines how different strategic agendas, aesthetic aims and technical systems shaped U.S.-French broadcasting and the cultural politics linking the United States and France.

Dangerous Learning

Dangerous Learning

YALE UNIVERSITY PRESS

The enduring legacy of the nineteenth-century struggle for Black literacy in the American South Few have ever valued literacy as much as the enslaved Black people of the American South. For them, it was more than a means to a better life; it was a gateway to freedom and, in some instances, a tool for inspiring revolt. And few governments tried harder to suppress literacy than did those in the South. Everyone understood that knowledge was power: power to keep a person enslaved in mind and body, power to resist oppression. In the decades before the Civil War, Southern governments drove Black literacy underground, but it was too precious to be entirely stamped out. This book describes the violent lengths to which southern leaders went to repress Black literacy and the extraordinary courage it took Black people to resist. Derek W. Black shows how, from the beginning of the nineteenth century to the end of Reconstruction, literacy evolved from a subversive gateway to freedom to a public program to extend citizenship and build democratic institutions—and how, once Reconstruction was abandoned, opposition to educating Black children depressed education throughout the South for Black and white students alike. He also reveals the deep imprint those events had on education and how this legacy is resurfacing today.

After AI: Strategies to Survive & Thrive

After AI: Strategies to Survive & Thrive

Derek W. Pearson

Roof Media

In the next few decades, the proliferation of Artificially Intelligent technology will have a significant impact on our ability to earn a living. Cheaper AI options will displace many human workers in both "skilled" and "unskilled" jobs, and in many cases a traditional education will not constitute a tangible advantage over AI alternatives. "After AI: Strategies to Survive & Thrive" examines ways to actively promote the natural human attributes that give us that advantage: the stuff that makes us MORE THAN MACHINES.
Inorganic Substances

Inorganic Substances

Derek W. Smith

Cambridge University Press
1990
pokkari
Inorganic Substances is complementary in its approach to conventional inorganic chemistry textbooks. Written with the undergraduate in mind, it gives an introduction to descriptive inorganic chemistry, a systematic survey of the chemistry of the elements according to the Periodic Classification. In this way, the reader acquires a firm grasp of the principles which underlie which inorganic substances can be made, their preparations, structures, chemical reactions and physical properties. The book presents theory as a background to the facts of inorganic chemistry, rather than as an end in itself. It does not concentrate on structural detail or reaction mechanisms but stresses the interplay between thermodynamic and kinetic considerations in understanding stability. The ways in which the various theories of structure and bonding are related are thoroughly dealt with throughout. The approach of this book makes it a useful companion to any intermediate inorganic chemistry course. It should also be useful to other science students, especially earth and material scientists who need a good grounding in modern inorganic chemistry.
A Political History of Western Europe Since 1945
Taking a thematic approach, Derek Urwin addresses the major political and economic developments in western Europe since World War II, right up to the present day. The book covers issues and developments in national politics, and the movement towards greater unity in Western Europe and the role of Europe in global politics and in the international economy. The text has been revised throughout and updated to take account of the political consequences of the ending of the Cold War and the troubled progress of European integration since Maastricht. The Fifth Edition has lost nothing of its predecessor's clarity and accessibility and in its updated form will win the book a host of new admirers.
Tragedy and Citizenship

Tragedy and Citizenship

Derek W. M. Barker

State University of New York Press
2009
pokkari
A study of attitudes towards tragedy in both democratic and nondemocractic political theory.Tragedy and Citizenship provides a wide-ranging exploration of attitudes toward tragedy and their implications for politics. Derek W. M. Barker reads the history of political thought as a contest between the tragic view of politics that accepts conflict and uncertainty, and an optimistic perspective that sees conflict as self-dissolving. Drawing on Aristotle's political thought, alongside a novel reading of the Antigone that centers on Haemon, its most neglected character, Barker provides contemporary democratic theory with a theory of tragedy. He sees Hegel's philosophy of reconciliation as a critical turning point that results in the elimination of citizenship. By linking Hegel's failure to address the tragic dimensions of politics to Richard Rorty, John Rawls, and Judith Butler, Barkeroffers a major reassessment of contemporary political theory and a fresh perspective on the most urgent challenges facing democratic politics.Derek W. M. Barker is a program officer at the Kettering Foundation.
