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
