Description
Synopsis: Describes Kepler's argument for basing orbital predictions on the actual position of the Sun instead of the hypothetical mean position.
Opening line: "All right, let's go back to part one. I said what point in part one is to establish that we should be referring all motions to the actual Sun, not to the mean Sun."
