We describe a new physics course that explores the interaction among science, technology, war, and military affairs since the 1980s; topics covered include the Manhattan project, weapons technology, strategic thinking, disarmament and government support of research. The course is part of a new interdepartmental ldquo;Program for the Study of Peace and War.” We emphasize the valid role of general physics courses in studying areas where the results and methods of physics have an important impact on society.
