Considering the the RGO has split views on what the axial rotation of
the Earth through 360 degrees is wrt the Sun,I can only conclude that
you in the U.K. have adopted a century's worth of linguistic trash and
are happy to play your part in consigning your own heritage and
astronomy to the most ignoble level possible.

If you can't figure out why the axial rotation is 24 hours through 360
degrees,don't bother doing astronomy and take up stamp collecting or
gardening instead for otherwise you may possibly be the dumbest people
ever to set foot on the planet,no two ways about it.



" The Earth rotates 360º in a sidereal day. Its motion around the Sun
means that it has to rotate 361º for the Sun to return to the same
position in the sky - a solar day."

" In 24 hours the Earth rotates through 360° with respect to the Sun.
Each time zone is then theoretically 15° wide, corresponding to a 1
hour difference in mean solar time. "

Yup, that sounds like us. Have you considered writing us off and
spreading the word on more fertile ground. We promise not to be too
sad if you bugger off..

no it doesn't. You're just clinically thick, and a troll to boot. Go
back under your bridge.

Leaving aside the meat grinder that you have put the language through
recently, this dumb Brit is going to try one last time!
Get the hang of these concepts and it will all fall together.
Apparent solar day = meridian transit interval of the sun (variable).
Mean solar day = 86400 seconds (that's S.I.seconds, just the same
seconds that John Harrison used)
86400s = 24 hours.
360/24 = 1 hour angle = 15 degrees.
24 hour angles = 1 axial revolution of the earth = 1 sidereal day.
Note that an 'hour' is not the same as an 'hour angle'
Look up the arbitrary definition of a S.I. second and ask yourself why
it is that particular number of cycles.

Finally, don't bother to state that the mean solar day is currently
about 0.05ms longer, that's Newton's fault. Einstein had nothing to do
with it.

No and no. The Mean Solar Day is no longer 86400 SI seconds long and
Harrison *certainly* didn't use any sort of SI measurements.

Look up the arbitrary definition of a S.I. second and ask yourself why
it is that particular number of cycles.

Because of the length of the MSD at the end of the nineteenth century.

Neither did Newton, it was his star pupil Halley who first noticed that
the rotation of the Earth has varied since the records of the
Babylonians were made.

Funny,funny,funny !.

I guess two 'Piltdown man' scams in a century is too much to bear
(btw,I loved the cricket bat signature of the hoaxer) but ultimately
the relativity scam is a much more satisfying hoax to solve.All it
takes is the uncomfortable feeling that emerges when the RGO goes to
explain what the axial rotation of the Earth through 360 degrees is
and everything else follows.

" The Earth rotates 360º in a sidereal day. Its motion around the Sun
means that it has to rotate 361º for the Sun to return to the same
position in the sky - a solar day."

http://www.nmm.ac.uk/site/navId/00500300l005001000

" In 24 hours the Earth rotates through 360° with respect to the Sun.
Each time zone is then theoretically 15° wide, corresponding to a 1
hour difference in mean solar time. "

In any case,Denis ,a really, really funny attempt on your part and I
appreceate a good chuckle at your attempt,no offense intended.

No and no. The Mean Solar Day is no longer 86400 SI seconds long and
Harrison *certainly* didn't use any sort of SI measurements.

The duration of a Mean Solar Day is, AFAIK, an arbitrary definition of
86400s at epoch 1820. If this has changed I'd be pleased to hear about
it,
and of course Harrison knew nothing of SI units, SI already had a
definition to be incorporated into its arbitrary set of definitions.
That's why Harrison's seconds are the same as SI's.

Look up the arbitrary definition of a S.I. second and ask yourself why
it is that particular number of cycles.

Because of the length of the MSD at the end of the nineteenth century.
Exactly! (If you mean epoch 1820) See above

Finally, don't bother to state that the mean solar day is currently
about 0.05ms longer, that's Newton's fault. Einstein had nothing to do

Babylonians were made.

Dave.

In the sense that Newton gave us the means to understand why the
rotation varies, it was his 'fault'. Please bear in mind my somewhat
facetious response to Gerald/Oriel36 was based on my suspicion that he
was merely seeking to provoke an argument about relativity, rather than
having any constructive conversation about orbital mechanics.
His continuation of this in another thread just confirms my suspicions.
