I had the chance to have an unofficial interview with Kirby Runyon. (Planetary science is a very publicity-heavy field, and planetary scientists often labor under certain constraints regarding their contact with the media. We avoided mentioning his institutional affiliation to emphasize the point that this interview in no way characterizes any official position by his institution. You can find out where he works, and get access to some of his work, via web search if you are curious, and there's a clue around 13:00 as well.)
We opened the interview with a discussion of Kirby's research on surface processes on planets. He works on data returned from the Moon, Mars, and Saturn's moon Titan to evaluate how winds, asteroid impacts, and other forces shape the surfaces of those bodies.

In this episode we try to give a little workshop on thinking for yourself about a thorny passage in the Bible, specifically what we are to make of this star that supposedly influenced the Magi (wizards? astrologers?) from "the east" to come to Jerusalem looking for Jesus.

The times below are continuations from the last episode. My opening is about 1:30, and then we start with galaxy motions at "26:00".
26:00 Galaxy motions
27:00 Galaxy rotation curves: do not match Keplerian orbits
28:00 Galaxies spin more like records (laggy soft records); mass distribution is nothing like the Solar System
29:00 Hurricanes as a better analogy for galaxies
30:00 Stars in a galaxy move in local organization
32:00 Nebulas
34:00 The opposite extreme: rigid body rotation
35:00 Gravitational attraction between stars creating coherence
36:00 Curiosity that gravity and electrical forces are both inverse square laws
37:00 Poisson's equation
38:00 Summing densities in Poisson's inhomogeneous term is physically meaningless; intensive quantities can't be summed that way
40:00 Gauss' theorem: flux through a surface and quantity within a volume
41:00 Summing is for extensive variables
42:00 Pressure an ambiguous variable
43:00 Future work
44:00 Thermal expansivity: Giauque
45:00 Problems with the glass transition measurements done in the past: need to completely drive out water from the experimental charges
48:00 Wrapup
