In The Power of Systems, Egl? Rindzevi?i?t? introduces readers to one of the best-kept secrets of the Cold War: the International Institute of Applied Systems Analysis (IIASA), an international think tank established by the US and USSR to advance scientific collaboration. From 1972 until the late 1980s, IIASA was one of the very few permanent platforms where policy scientists from both sides of the Cold War could work together to articulate and solve world problems: a rare zone of freedom, communication, and negotiation.East-West scientists coproduced computer simulations of the long-term world future, using global modeling to explore the possible effects of climate change and nuclear winter. Their concern with global issues also became a vehicle for transformation inside the Soviet Union. The Power of Systems explores how computer modeling, cybernetics, and the systems approach challenged Soviet governance by undermining the linear notions of control on which Soviet governance was based and creating new objects and techniques of government.
