Allan Milne Lees, I’ve just started watching this: “Leonard Susskind on Richard Feynman, the Holographic Principle, and Unanswered Questions in Physics.” I read “Surely, You Must Be Joking, Mr. Feynman” in high school and so this interview caught my eye. I don’t think it’s a part of the series that you recommended, but it’s got me started in listening to Susskind in any case.
