Great recommendation. When I first listened to this podcast, I was impressed by how the conversation managed to hit the sweet spot of engagement for both non technical (a friend I shared it with) and technical/mathematical (myself) audiences. Later learned that Melvyn Bragg hosted two of guests here (Gowers and Roney-Dougal) for another good conversation on the notions of randomness and pseudo-randomness.
