To celebrate, we’re going to have more than the usual number of podcasts about quantum mechanics over the next couple of months. Today is an experimental flipped podcast, in which I’m being interviewed by Rob Reid. Rob is the host of the After On podcast, of which this is also an episode. We talk about quantum mechanics generally and my favorite Many-Worlds approach in particular, homing in on the motivation for believing in all those worlds and the potential puzzles that this perspective raises.
