Sean, an intriguing episode. It’s great to hear the interesting directions you’d like to move and the sorts of non-physics topics you’re planning on covering. Given some of the areas relating to communication and democracy that you’d like to cover, I might recommend taking a look at a few of the following potential guests:

George Lakoff, a retired Distinguished Professor of Cognitive Science and Linguistics at the University of California at Berkeley, has some solid ideas about how we communicate as well as how Donald J. Trump’s speech is  influencing our current politics and changing the way that journalism operates in our democracy.

Alan Alda, a science communicator and podcast host of Clear+Vivid and, yes, the well known actor from stage and screen (including M.A.S.H.), who has a long running podcast on the topic of communication and how we communicate. If you’re not listening to it already, it has many of the communication related ideas around who we are, how democracy works through communication, how our tribal tendencies effect the world, etc. (You’ll likely appreciate his podcast in general and may want to mine some of it for guests for your own show.) If you’re able, perhaps do it as a pair of crossover episodes in which you interview him and another in which he interviews you? I think both of your audiences will appreciate such a set of interviews, and you’ll have a chance to do a more extended exploration of both your separate as well as common areas of interests. (There’s also an odd similarity to the theme music for both of your shows…)
