I don't know what the big deal is - Isaac used an Ra/Dec framework as
a common denominator between absolute/relative space and motion where
he assumes that observations seen from Earth reflect relative space
and motion while observations from the Sun reflect absolute space and
motion - a sort of double modeling that doesn't work -
"That the fixed stars being at rest, the periodic times of the five
primary planets, and (whether of the sun about the earth, or) of the
earth about the sun, are in the sesquiplicate proportion of their mean
distances from the sun. This proportion, first observed by Kepler, is
now received by all astronomers; for the periodic times are the same,
and the dimensions of the orbits are the same, whether the sun
revolves about the earth, or the earth about the sun." Newton
There is an actual point behind what Isaac was trying to do and
because he bases his absolute/relative time on a half-baked version of
the Equation of Time is no reason to disregard any of it,not even Mach
figured out what Newton was doing with astronomy and the principles
that go into observations and there interpretation -
"This absolute time can be measured by comparison with no motion; it
has therefore neither a practical nor a scientific value; and no one
is justified in saying that he knows aught about it. It is an idle
metaphysical conception." Mach, Analyse der Empfindungen, 6th ed.
It seems mathematicians are terrified of dealing with actual
observations rather than just words that exist in their imagination
and Newton was simply making things up as he went along,nothing more
or less.Wish it were possible to find people who are interested in
putting everything in context instead of chanting voodoo at the thing.
