Radiant Science, Dark Politics: A Memoir of the Nuclear Age is a compelling personal account that interweaves the scientific breakthroughs of the 20th century with the turbulent political climate of the Cold War. Written by a scientist who stood at the forefront of nuclear research, the memoir provides an intimate look at the discovery of carbon-14, the rise of Big Science, and the moral dilemmas faced by those working at the intersection of physics, chemistry, and national security. The book offers a rich narrative about the author's interactions with some of the greatest scientific minds of the era--Niels Bohr, J. Robert Oppenheimer, Glenn Seaborg, and many others--while detailing the exhilarating and often chaotic atmosphere of the Radiation Laboratory at Berkeley. Through firsthand accounts, the book captures the excitement of pioneering discoveries in nuclear science and isotopic tracing, shedding light on the transformative impact of these breakthroughs on biology and medicine. Yet Radiant Science, Dark Politics is more than a scientific memoir--it is also a deeply personal story of persecution and resilience. The author recounts his harrowing experiences with the House Un-American Activities Committee, which sought to brand him a traitor based on unfounded suspicions. His struggle against political blacklisting and the assault on academic freedom reflects a darker chapter in American history, when Cold War paranoia threatened the careers of countless scientists. This memoir serves as both a tribute to scientific progress and a cautionary tale about the dangers of ideological extremism. By blending personal narrative with historical insight, Radiant Science, Dark Politics offers a unique perspective on the nuclear age, revealing the costs--both intellectual and personal--of being at the forefront of discovery in a politically charged world.
