This official history was originally printed in very small numbers in 2002. "Defense's Nuclear Agency, 1947-1997" traces the development of the Armed Forces Special Weapons Project (AFSWP), and its descendant government organizations, from its original founding in 1947 to 1997. After the disestablishment of the Manhattan Engineering District (MED) in 1947, AFSWP was formed to provide military training in nuclear weapons' operations. Over the years, its sequential descendant organizations have been the Defense Atomic Support Agency (DASA) from 1959 to 1971, the Defense Nuclear Agency (DNA) from 1971 to 1996, and the Defense Special Weapons Agency (DSWA) from 1996 to 1998. In 1998, DSWA, the On-Site Inspection Agency, the Defense Technology Security Administration, and selected elements of the Office of Secretary of Defense were combined to form the Defense Threat Reduction Agency (DTRA).
Provides a detailed investigation of various facets of America's involvement with nuclear power--including both wartime and peacetime applications--and exposes the dangers of and potential disasters in the nuclear industry
A history of the origins and development of the American atomic bomb program during WWII. Begins with the scientific developments of the pre-war years. Details the role of the U.S. government in conducting a secret, nationwide enterprise that took science from the laboratory and into combat with an entirely new type of weapon. Concludes with a discussion of the immediate postwar period, the debate over the Atomic Energy Act of 1946, and the founding of the Atomic Energy Commission. Chapters: the Einstein letter; physics background, 1919-1939; early government support; the atomic bomb and American strategy; and the Manhattan district in peacetime. Illustrated.
Project 1.7 of Operation TEAPOT was concerned with the measurement of surface and subsurface effects of an underground explosion of a 1.2-kt nuclear burst (Shot 7). The measurements included free-field earth and airblast effects, as well as loading on underground structural devices. This report deals with the presentation and analysis of the free-field data only; the structural data have been transmitted to the appropriate agencies for their analysis. From the 76 channels installed on TEAPOT Shot 7, 75 usable records were obtained. The free-field quantities measured include air-blast pressure, earth acceleration, earth stress and strain, and permanent earth displacement. The results are discussed by phenomenon and, in each case, the TEAPOT data are compared with pretest predictions. Also, where data are available, comparisons are made with previous underground nuclear test results. Some aspects of seismology and soil mechanics as applied to underground explosion phenomena are presented and, finally, the most pertinent high explosives results from subsequent tests conducted at the TEAPOT location are summarized.

Longtime activist, author, and antifeminist leader Phyllis Schlafly is for many the symbol of the conservative movement in America. In this provocative new book, historian Donald T. Critchlow sheds new light on Schlafly's life and on the unappreciated role her grassroots activism played in transforming America's political landscape. Based on exclusive and unrestricted access to Schlafly's papers as well as sixty other archival collections, the book reveals for the first time the inside story of this Missouri-born mother of six who became one of the most controversial forces in modern political history. It takes us from Schlafly's political beginnings in the Republican Right after the World War II through her years as an anticommunist crusader to her more recent efforts to thwart same-sex marriage and stem the flow of illegal immigrants. Schlafly's political career took off after her book A Choice Not an Echo helped secure Barry Goldwater's nomination. With sales of more than 3 million copies, the book established her as a national voice within the conservative movement. But it was Schlafly's bid to defeat the Equal Rights Amendment that gained her a grassroots following. Her anti-ERA crusade attracted hundreds of thousands of women into the conservative fold and earned her a name as feminism's most ardent opponent. In the 1970s, Schlafly founded the Eagle Forum, a Washington-based conservative policy organization that today claims a membership of 50,000 women. Filled with fresh insights into these and other initiatives, Phyllis Schlafly and Grassroots Conservatism provides a telling profile of one of the most influential activists in recent history. Sure to invite spirited debate, it casts new light on a major shift in American politics, the emergence of the Republican Right.
If you have ever looked at a fantastic adventure or science fiction movie, or an amazingly complex and rich computer game, or a TV commercial where cars or gas pumps or biscuits behaved liked people and wondered, “How do they do that?”, then you’ve experienced the magic of 3D worlds generated by a computer. 3D in computers began as a way to represent automotive designs and illustrate the construction of molecules. 3D graphics use evolved to visualizations of simulated data and artistic representations of imaginary worlds. In order to overcome the processing limitations of the computer, graphics had to exploit the characteristics of the eye and brain, and develop visual tricks to simulate realism. The goal is to create graphics images that will overcome the visual cues that cause disbelief and tell the viewer this is not real. Thousands of people over thousands of years have developed the building blocks and made the discoveries in mathematics and science to make such 3D magic possible, and The History of Visual Magic in Computers is dedicated to all of them and tells a little of their story. It traces the earliest understanding of 3D and then foundational mathematics to explain and construct 3D; from mechanical computers up to today’s tablets. Several of the amazing computer graphics algorithms and tricks came of periods where eruptions of new ideas and techniques seem to occur all at once. Applications emerged as the fundamentals of how to draw lines and create realistic images were better understood, leading to hardware 3D controllers that drive the display all the way to stereovision and virtual reality.
