This seminar examines the history and legacy of the Cold War on American science. It explores scientist’s new political roles after World War II, ranging from elite policy makers in the nuclear age to victims of domestic anti Communism. It also examines the changing institutions in which the physical sciences and social sciences were conducted during the postwar decades, investigating possible epistemic effects on forms of knowledge. The subject closes by considering the place of science in the post-Cold War era.

This OER explores the debates over the solar system in the seventeenth century, focusing on the relationship between models and data during this time period. It contains both an activity as well as resources for further exploration. It is a product of the OU Academy of the Lynx, developed in conjunction with the Galileo's World Exhibition at the University of Oklahoma.
