STS.042J - Einstein, Oppenheimer, Feynman: Physics in the 20th Century

STS.042J - Einstein, Oppenheimer, Feynman: Physics in the 20th Century (Fall 2020, MIT OCW). Instructor: Prof. David Kaiser. This class explores the changing roles of physics and physicists during the 20th century. Topics range from relativity theory and quantum mechanics to high-energy physics and cosmology. We examine the development of modern physics and the role of physicists within shifting institutional, cultural, and political contexts, such as Imperial Britain, Nazi Germany, and the US during World War II, and the Cold War.

Lecture 24 - The Big Bang, Cosmic Inflation, and the Latest Observations

Prof. Kaiser discusses the successes and shortcomings of the big bang model, cosmic inflation, and large-scale structure.
