Default Anatomy of a conceptual disaster

In the relativity forum there is a diversified bunch but they all thread the same wheel in neither getting closer nor further from the truth. The issue wouldn't be Newton's description of the Equation of Time as a definition of time but rather Huygen's description which Newton tried to imitate -


" Here take notice, that the Sun or the Earth passeth the 12. Signes, or makes an entire revolution in the Ecliptick in 365 days, 5 hours 49 min. or there about, and that those days, reckon'd from noon to noon, are of different lenghts; as is known to all that are vers'd in Astronomy. Now between the longest and the shortest of those days, a day may be taken of such a length, as 365 such days, 5. hours &c. (the same numbers as before) make up, or are equall to that revolution: And this is call'd the Equal or Mean day, according to which the Watches are to be set; and therefore the Hour or Minute shew'd by the Watches, though they be perfectly Iust and equal, must needs differ almost continually from those that are shew'd by the Sun, or are reckon'd according to its Motion. But this Difference is regular, and is otherwise call'd the Aequation " Huygens

The first line is where a lot of damage was done insofar as it introduced not only a geocentric/heliocentric equivalency but omits the fact the Equation of Time(keeping) is a child of the calendar system as it relies on the observed passage of the Sun across the observer's meridian including February 29th.

Of greater consequence is the natural inequality itself as it registers two separate rotations in one observation, assuming daily rotation is constant while the natural inequality is an effect of the variable orbital speed of the Earth in terms of the other rotation responsible for the polar day/night cycle and the seasons where it combines with intrinsic rotation (variation is speeds across latitudes).

Now people can move to the relativity forum which represents theoretical junk dumped into the celestial arena as astronomy even though the practitioners know nothing of the technical details which comprise Newton's definitions which are not definitions at all. There are no special people, no icons, no genius,no celebrity, just the opportunity to work on a new view of the planets and moons as they circle their respective centers with the cumulative effects giving more expansive perspectives and especially with electromagnetic influences.
