Subject: Astronomical Measurements of the Angular Velocity
| I think that the astronomers still measure angular velocity through Kepler’s second law of 1609, equal areas in equal times. They must have supercomputers to do this with phenomenal accuracy in the solar system. Knowing this, dr / dt can be found from the chain rule:
dr / dt = (dr / dtheta)(dtheta / dt) and in the solar system dr / dtheta is found from the observations of a precessing ellipse, the precession of the perihelion corrected by supercomputer for the gravitational effects of other objects, and other corrections. All the concepts that we have used are spectacularly correct, and congratulations on the computer algebra. These are all major advances in cosmology.
