ToDo list

 * Unfortunately, the state of celestial/orbital mechanics in Wikipedia is scattered, disorganized, redundant. Where does one begin?
 * I had started documenting some of the problems here, but it was becoming overwhelming. Letting it go. Tfr000 (talk) 14:36, 30 January 2016 (UTC)
 * for a mechanics article which has been worked over into something pretty decent, see Classical_central-force_problem Tfr000 (talk) 22:43, 29 November 2015 (UTC)
 * Astronomical_system_of_units needs to be fixed. Some just plain wrong information in it. Tfr000 (talk) 13:42, 6 December 2015 (UTC)
 * Still need to do some research into where the term anomaly came from. Kepler? Apparently, anomaly is a very ancient term, going back to Ptolemy and the Almagest at least. It was Kepler who gave precise definitions to the anomalies which we now associate with orbital mechanics. Tfr000 (talk) 22:43, 29 November 2015 (UTC)
 * true longitude is a stub.
 * true anomaly has no real references. It needs some kind of flow. It's currently a bunch of scattered equations.
 * angular momentum:
 * add something about dimensions...? might be a bit odd for something like ang mom.
 * re-organize some of the math sections, especially "solid body"
 * perhaps add some graphics  Tfr000 (talk) 22:27, 7 July 2015 (UTC)
 * Torque: Here is the entire History section: "The concept of torque, also called moment or couple, originated with the studies of Archimedes on levers. The rotational analogues of force, mass, and acceleration are torque, moment of inertia and angular acceleration, respectively." One of these two sentences has nothing to do with history! Tfr000 (talk) 19:24, 24 May 2015 (UTC) Partially fixed now. It needs some research into "moment of force" and whatnot. Tfr000 (talk) 11:46, 26 May 2015 (UTC)
