In mid October the Origins Project Foundation ran two public events in California. The second event was held at the Air and Space Museum in San Diego. I had asked my colleague Brian Keating, who teaches at UCSD and is a Trustee of that museum, whether he might be interested in doing a public dialogue together that we could later both broadcast on our respective podcasts. He and I have each appeared before on each other’s podcasts, and I knew that we could have the kind of comfortable, informative, and fun conversation that might appeal to a live audience, which would make for a different kind of podcast. I am happy to present here the video record of that live-audience podcast, and the Q&A with the audience that was recorded right after it. Brian and I discussed many things, from forefront cosmology, to the nature of teaching and doing research, as viewed by an experimentalist and a theorist respectively, as well as broader questions associated with science in society today. The questions afterwards were equally interesting. I hope you enjoy both as you listen to or watch the podcast.
