Kaiser's historical research focuses on the development of physics in the United States during the Cold War, looking at how the discipline has evolved at the intersection of politics, culture, and the changing shape of higher education. His physics research focuses on early-universe cosmology, working at the interface of particle physics and gravitation. He has also helped to design and conduct novel experiments to test the foundations of quantum theory.He is presently Chair of the Editorial Board of MIT Press, and also serves on the advisory boards for Nautilus and Undark magazines. Kaiser's work has been featured in such venues as Nature, Science, and Scientific American; the New York Times, the New Yorker, the Huffington Post, and the London Review of Books; and on National Public Radio, BBC Radio, and NOVA television programs. On this episode, he sits down with James Ryerson to discuss his career, the nature of quantum entanglement, and the life and afterlife of a New York Times piece he wrote about the history and science of physics in November 2014.
