Starting simultaneously with the rise to power of an obscure Soviet bureaucrat named Mikhail Gorbachev, the scientists’ boycott not only led to the end of the Cold War, but the end of the Soviet Union itself. This book presents an entirely new perspective on how the Cold War ended without triggering apocalyptic nuclear war, always present as a possible endpoint of the Cold War conflict between the U.S. and the U.S.S.R. The importance of exploring this new perspective is that it helps us to understand the risks to the U.S. of learning the wrong lessons from its Cold War “victory”, and how to stop the current and accelerating unraveling of the Cold War stand down and the re-emerging threat of apocalyptic nuclear war. https://images.squarespace-cdn.com/content/v1/627c6029893a6a2653f70772/ee5927e3-b6ba-4da9-828c-d5b67500c992/extreme+physics.png Books - Extreme Physics Most matter in the Universe, from the deep interior of planets to the core of stars, is at high temperature or high pressure compared to the matter of our ordinary experience. This book offers a comprehensive introduction to the basic physical theory on matter at such extreme conditions and the mathematical modeling techniques involved in numerical simulations of its properties and behavior. Focusing on computational modeling, the book discusses topics such as the basic properties of dense plasmas; ionization physics; the physical mechanisms by which laser light is absorbed in matter; radiation transport in matter; the basics of hydrodynamics and shock-wave formation and propagation; and numerical simulation of radiation-hydrodynamics phenomenology. End-of-chapter exercises allow the reader to test their understanding of the material and introduce additional physics, making this an invaluable resource for researchers and graduate students in this broad and interdisciplinary area of physics. https://www.jeffcolvin.net/events daily 0.75 2025-02-03 https://images.squarespace-cdn.com/content/v1/627c6029893a6a2653f70772/1693363392834-ADV3NFKJFFN7HF3XB6CL/image-asset.jpeg Events Book Talk and Book Signing Event Coming up in Spring 2026 The Institute for Retired Persons, 300 Ridgeview Chambersburg, PA 17201 https://images.squarespace-cdn.com/content/v1/627c6029893a6a2653f70772/333c5380-665f-4735-a9c8-47430a4d0bab/image-asset.jpg Events Book Talk and Book Signing Event Sunday September 28, 7:00 PM Cold War Museum, Vint Hill, VA Via Zoom: THE COLD WAR MUSEUM® https://images.squarespace-cdn.com/content/v1/627c6029893a6a2653f70772/1683926170040-I4PA79MRVPMPRSRFKIRP/unsplash-image-dGxOgeXAXm8.jpg Events Book Talk and Book Signing Event Tuesday March 18, 2025, 5:30 PM Fuller Lodge, Central Avenue Los Alamos, New Mexico 87544 https://images.squarespace-cdn.com/content/v1/627c6029893a6a2653f70772/1683926268335-NP771QJSRCV28HVQ0VJ5/unsplash-image-IS7WfX_f_ug.jpg Events Book Talk and Book Signing Event Tuesday June 17, 2025, 6:00 PM Adams County Library, 140 Baltimore St. Gettysburg, PA 17325 https://www.jeffcolvin.net/contact-us daily 0.75 2023-08-30 https://www.jeffcolvin.net/oped/end-the-electoral-college daily 0.75 2022-05-19 https://www.jeffcolvin.net/oped-the-slow-motion-coup daily 0.75 2022-05-19 https://www.jeffcolvin.net/oped-ukraine-and-the-slow-motion-coup daily 0.75 2022-05-19 https://www.jeffcolvin.net/about daily 0.75 2022-05-20 https://images.squarespace-cdn.com/content/v1/627c6029893a6a2653f70772/d46979d5-f4ee-4969-bd45-0a297f069cdc/Screen+Shot+2022-05-11+at+7.15.54+PM.png About - About Jeff Colvin Jeff has spent the past 45 years as a research physicist helping to develop the science that has made technically possible a Comprehensive Test Ban Treaty (CTBT), one linchpin of the Cold War stand-down discussed in his new book, Avoiding Apocalypse. He is the author or co-author of nearly 100 peer-reviewed scientific publications; has written (with Jon Larsen) what has now become the standard graduate-level text book in the new field of physics that grew out of Cold War era nuclear weapons development (click HERE for information on this book); played a leadership role in organizing the scientists' boycott and aiding dissident and refusenik Soviet scientists; held an appointed position in the U.S. Department of Energy in Washington, D.C. during the George H. W. Bush administration; and has written and published several Op-Ed columns on these and related topics in different newspapers over the years. He lives part-time in Livermore, California and part-time in Gettysburg, Pennsylvania with his wife, Mary Frances.
