20th-Century Physics and Society: Einstein, Oppenheimer, and Feynman

How did the abstract theories of relativity and quantum mechanics move from quiet academic blackboards to the very center of global geopolitics? Understanding the history of modern physics requires looking beyond the formulas to the historical, political, and cultural forces that drove scientific discovery. In this text-based course, you will trace the evolution of twentieth-century physics through the lives and work of its most influential figures, including Albert Einstein, J. Robert Oppenheimer, and Richard Feynman. What you'll learn: - Understand the foundational concepts of relativity, quantum mechanics, and cosmology through clear, non-mathematical explanations. - Analyze the shifting role of physicists as they transitioned from academic researchers to key political advisors and defense developers. - Examine the impact of major historical contexts, including World War II and the Cold War, on scientific funding and research priorities. - Evaluate the profound ethical dilemmas faced by scientists during the development of the atomic bomb and subsequent nuclear arms race. - Explore the transition from small-scale laboratory research to modern "Big Science" and contemporary global research frameworks. This course begins by establishing key terminology and early-century scientific concepts before tracing the chronological flow of institutional and political changes. Through structured readings and conceptual exercises, you will gain a deep appreciation for the human and political stories behind scientific progress. Designed entirely for beginners, this course requires no prior background in advanced physics or history.
