David Gross on The Origins Podcast with Lawrence Krauss (audio)

Lawrence Krauss recently had the pleasure of sitting down with David Gross, one of the preeminent theoretical physicists who has been involved not just in the development of the theory of the strong interaction, called quantum chromodynamics, but he is also one of the founders and developers of String Theory. In their discussion, they explore the growth and changes of physics from the 1950's all the way to current day discoveries and methodologies.
