Carroll & Albert on Many Worlds

Again following Leiter by a few days, there is an excellent 67-minute discussion of quantum mechanics between physicist Sean Carroll and philosopher of physics David Albert at bloggingheads. The first 41 minutes are an ideal introduction for people who have not been exposed to the issues before, but beginning here there is a more advanced investigation of the prospects for accounting for probabilities in many worlds.

Two moments to watch for: (i) Albert's remark that the only reason to write books is to regret writing them and (ii) Carroll's brief expressions of bemusement as Albert sharpens philosophical distinctions like reasons vs. causes.
