the stupid objections of celestial sphere geometers there can be no
excuse for the silence surrounding one of the most fundamental
astronomical correlations of all .

Gezza lad, for once please tell me what you alone have acomplished or
contributed to the subject.
Try to move away from the monitor, go outside and put a stick in the
ground.
Over the next year or so mark the position of the stick's shadow at 24
hour intervals (or measure the time interval between the shadow's
successive returns to the original mark).

Let me show you what you believe through Flamsteed's justification of
the return of a star to a meridian -

http://www.nmm.ac.uk/server/show/nav.00500300l005001000

In your mind a shadow returns to noon in 24 hours exactly in order to
justify the reurn of a star in 23 hours 56 minutes 04 seconds.

I can no longer compete with such rubbish as the NMM explanation above
when the actual principles which correlate clocks with axial rotation
through the noon Equation of Time correction at precisely 4 minutes for
each degree of rotation are so gorgeous that I have trouble imagining
why anyone would intentionally destroy it


After the year has elapsed come back and discuss your observations.
Do try not to live vicariously through better astronomers and thinkers
than yourself.
Should we require the worthy Kepler's thoughts on the subject we know
well where to find them. When we require your direction on procreation
be assured we will seek you out.

Most of humanity already knows that the Earth rotates on its axis in 24
hours or 15 degrees per hour without knowing exactly how this
correlation came to be.I have presented the outlines of the two step
process which is partly pre-Copernican and partly heliocentric and it
is such a lovely intricate way of thinking .

Astrophotographers can still have the convenience of celestial sphere
geometry for observational purposes but justfying the Earth's axial and
orbital motions using celestial sphere geometry must cease.It remains
to be seen if an intuitive person can make the adjustment to
considering the Equation of Time system as a kind of daily 'leap'
adjustment to equalise the variations in the total length of the day.

Looking at your response with your stick/shadow it would embarrass me
to contend with you as the intricate reasoning of my astronomical
ancestors,both pre-Copernican and heliocentric , has already been cut
to pieces on my account.Our existence depends on the Earth's motions
and the heliocentric astronomers who first presented how the Earth
moves in two seperate ways deserve a better audience than celestial
sphere geometers.Whether genuine people make the effort to see how
axial motion and orbital motion can be appreciated in isolation from
each other remains something I cannot and would not care to influence.

The two step process which correlates axial rotation with the clocks
in 24 hours/360 degrees precisely is now open for anyone who cares to
explain it as a shared astronomical heritage which is gorgeous and
pragmatic.
