This book examines the ways in which studies of science intertwined with Cold War politics, in both familiar and less familiar "battlefields" of the Cold War. Taken together, the essays highlight two primary roles for science studies as a new field of expertise institutionalized during the Cold War in different political regimes. Firstly, science studies played a political role in cultural Cold War in sustaining as well as destabilizing political ideologies in different political and national contexts. Secondly, it was an instrument of science policies in the early Cold War: the studies of science were promoted as the underpinning for the national policies framed with regard to both global geopolitics and local national priorities. As this book demonstrates, however, the wider we cast our net, extending our histories beyond the more researched developments in the Anglophone West, the more complex and ambivalent both the "science studies" and "the Cold War" become outside these more familiar spaces. The national stories collected in this book may appear incommensurable with what we know as science studies today, but these stories present a vantage point from which to pluralize some of the visions that were constitutive to the construction of "Cold War" as a juxtaposition of the liberal democracies in the "West" and the communist "East."

In the fall of 1950, newspapers around the world reported that the Italian-born nuclear physicist Bruno Pontecorvo and his family had mysteriously disappeared while returning to Britain from a holiday trip. Because Pontecorvo was known to be an expert working for the UK Atomic Energy Research Establishment, this raised immediate concern for the safety of atomic secrets, especially when it became known in the following months that he had defected to the Soviet Union. Was Pontecorvo a spy? Did he know and pass sensitive information about the bomb to Soviet experts? At the time, nuclear scientists, security personnel, Western government officials, and journalists assessed the case, but their efforts were inconclusive and speculations quickly turned to silence. In the years since, some have downplayed Pontecorvo's knowledge of atomic weaponry, while others have claimed him as part of a spy ring that infiltrated the Manhattan Project. "The Pontecorvo Affair" draws from newly disclosed sources to challenge previous attempts to solve the case, offering a balanced and well-documented account of Pontecorvo, his activities, and his possible motivations for defecting. Along the way, Simone Turchetti reconsiders the place of nuclear physics and nuclear physicists in the twentieth century and reveals that as the discipline's promise of military and industrial uses came to the fore, so did the enforcement of new secrecy provisions on the few experts in the world specializing in its application.
