The debate over scientists' social responsibility is a topic of great controversy today. Peter J. Kuznick here traces the origin of that debate to the 1930s and places it in a context that forces a reevaluation of the relationship between science and politics in twentieth-century America. Kuznick reveals how an influential segment of the American scientific community during the Depression era underwent a profound transformation in its social values and political beliefs, replacing a once-pervasive conservatism and antipathy to political involvement with a new ethic of social reform.

No professional group in the United States benefited more from World War II than the scientific community. After the atomic bombings of Hiroshima and Nagasaki, scientists enjoyed unprecedented public visibility and political influence as a new elite whose expertise now seemed critical to America's future. But as the United States grew committed to Cold War conflict with the Soviet Union and the ideology of anticommunism came to dominate American politics, scientists faced an increasingly vigorous regimen of security and loyalty clearances as well as the threat of intrusive investigations by the notorious House Committee on Un-American Activities and other government bodies. This book is the first major study of American scientists' encounters with Cold War anticommunism in the decade after World War II. By examining cases of individual scientists subjected to loyalty and security investigations, the organizational response of the scientific community to political attacks, and the relationships between Cold War ideology and postwar science policy, Jessica Wang demonstrates the stifling effects of anticommunist ideology on the politics of science. She exposes the deep divisions over the Cold War within the scientific community and provides a complex story of hard choices, a community in crisis, and roads not taken.

The epic story of how science went “big” and the forgotten genius who started it all—“entertaining, thoroughly researched…partly a biography, partly an account of the influence of Ernest Lawrence’s great idea, partly a short history of nuclear physics and the Bomb” (The Wall Street Journal). Since the 1930s, the scale of scientific endeavor has grown exponentially. The first particle accelerator could be held in its creator’s lap, while its successor grew to seventeen miles in circumference and cost ten billion dollars. We have invented the atomic bomb, put man on the moon, and probed the inner workings of nature at the scale of subatomic particles—all the result of Big Science, the model of industrial-scale research paid for by governments, departments of defense, and corporations that has driven the great scientific projects of our time. The birth of Big Science can be traced nearly nine decades ago in Berkeley, California, when a young scientist with a talent for physics declared, “I’m going to be famous!” His name was Ernest Orlando Lawrence. His invention, the cyclotron, would revolutionize nuclear physics, but that was only the beginning of its impact, which would be felt in academia, industry, and international politics. It was the beginning of Big Science. “An exciting book….A bright narrative that captures the wonder of nuclear physics without flying off into a physics Neverland….Big Science is an excellent summary of how physics became nuclear and changed the world” (The Plain Dealer, Cleveland). This is the “absorbing and expansive” (Los Angeles Times) story that is “important for understanding how science and politics entwine in the United States…with striking details and revealing quotations” (The New York Times Book Review).
