Appreceating orbital motion
Cataloguers hold to the view that the Earth keeps the same face to the
Sun over the course of an annual orbit. http://en.wikipedia.org/wiki/Sidereal_day There is no axial tilt component in the Equation of Time and it would be nice to see an astronomer explain to cataloguers why it is not a good idea to imagine that the Earth rotates constantly to a star every 23 hours 56 min 04 sec despite appearances. |

I am sorry that I mistook this for an astronomy forum.
Easy enough to see that Uranus changes its orbital orientation to the Sun by means of its unusual polar orientation and by analogy so does the Earth. What makes you justify you sidereal view for axial and orbital motion of the Earth would also break your own charter that you are discussing astronomy or astronomical matters.Are you absolutely sure the Earth's rotation through 360 degrees is 23 hours 56 min 04 sec ?. |

It's just that your definition of astronomy differs from the one that the majority hold, in particular the members of this group, and every professional astronomy association you care to name. Oh, and as regards your attempts to disparage astronomers as "cataloguers" have you stopped to think what the word "astronomy" actually means; what its etymology is? What makes you justify you sidereal view for axial and orbital motion of the Earth would also break your own charter that you are discussing astronomy or astronomical matters.Are you absolutely sure the Earth's rotation through 360 degrees is 23 hours 56 min 04 sec ?. With respect to the "fixed" stars, yes, I'm quite happy with that. And I haven't noticed any conflict with my religion either. I'm also quite willing to accept that you are not happy with it, so please just quietly hold your view, and let us quietly hold ours. Tim |

astronomer explain to cataloguers why it is not a
good idea to imagine that the Earth rotates constantly to a star every 23 hours 56 min 04 sec despite appearances. You should take this directly to the commercial telescope drive manufacturers. They will be more than grateful for your insights (as well as the major observatories) and will laud you to the heavens. No longer do we need different drive rates (solar,sidereal, lunar, King etc). Are you suggesting that time itself warps dependant on what class of object is being observed ? I suppose they effect cancels out as different observers look in different directions ? The rub comes when we all look the same way, the fabric of time will be stressed torsionally. We could name the new drive rate so engendered the "Kelleher Time With A Twist" rate. I wish you Sir a good "day". jc -- http://mysite.wanadoo-members.co.uk/jc_atm/ |

An astronomer would be capable of acknowledging the March 21st
alignment where the changing orbital orientation of the Earth runs parallel with axial longitude coordinates at 90 degrees to the Sun/Earth line. http://www.mhhe.com/physsci/astronom...ages/04f15.jpg Cataloguers frame the Equinox as the motion of the Sun across Equatorial latitudes at 90 degrees to the polar axis. http://scienceworld.wolfram.com/astronomy/Equinox.html Since the emergence of Copernican/Keplerian cosmology it should be taken for granted that the natural unequality from one noon to the next noon by means of the axial and orbital motion of the Earth is due to the changing rate of orbital orientation to the Sun as constant axial rotation is passing through it. Why vandalise the Equation of Time correction by determining that there is an equatorial orientation (axial tilt) component when it was simply a fudge by Flamsteed, Maskelyne and cataloguers to reduce celestial coordinates to terrestial coordinates. The vandalism emerges from the hijacking of astronomy by theorists begining with Newton.In their eagerness to demonstrate the Earth's constant axial rotation to a celestial sphere they created the impression of mean Sun/Earth distances which Newton exploited as a geocentric/heliocentric orbital equivalency.In short,the reasons you cataloguers imagine that the Earth's axial rotation through 360 degrees corresponds to 23 hours 56 min 04 sec is because it would be fatal to Newtonian concepts which conveniently drop axial and orbital motions as independent of each other. You are quietly supporting an intellectual holocaust,it surfaces every time when somebody comes here and declares how little engineers understand relativity or the general population are led to believe that Newton inherited the work of astronomers.I will not remain quiet because intentional pretensiousness influences children to accept insincerity while outwardly telling the world it stands for objective fact and no civilisation can support that. |

I can justify the fact that there is no external reference for constant
axial rotation through 360 degrees in 24 hours or the pace to which equable hours,minutes and seconds are set . Cataloguers and theorists created a mess by assuming that axial rotation to an external reference hence rotation to inertial space as a 'fact' and weakly supported by cataloguers as the 'true' value for axial rotation through 360 degrees. http://hypertextbook.com/facts/1999/JennyChen.shtml Have you any ****ing idea how many astronomical principles that were broken so Newton could have his ballistic agenda dumped on planetary motion ?. I suppose you can congratulate yourself that there is nobody around who would know the difference between Kepler's and Newton's view on the same topic and how it all ties in with why cataloguers support the wrong value for rotation of the Earth just to please the theorists or maybe because of cowardice. "PH=C6NOMENON IV. 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. http://members.tripod.com/~gravitee/phaenomena.htm "The proportion existing between the periodic times of any two planets is exactly the sesquiplicate proportion of the mean distances of the orbits, or as generally given,the squares of the periodic times are proportional to the cubes of the mean distances." Kepler Look up the term PANIS QUADRAGESIMALIS or the observed motion of Mars as seen from Earth which Kepler used in determining planetary geometry and motion,the chances are that you won't find it. You will however find plenty on Newton's procedure using the sidereal format based on the celestial sphere. http://www.friesian.com/separat.htm It must be great to know that there is nobody to challenge you or that you probably don't understand what Newton did but my business has been to return familiarity of astronomy to people as something more than celestial birdwatching and astronomers and their insights as wonderfully easy to appreceate. |

Fascinating. Now I've blocked him I only get the senssible replies.

Cheers Martin -- Martin Frey http://www.hadastro.org.uk N 51 02 E 0 47 Have'nt I told you that an astronomer recognises the equinox as an alignment between changing orbital orientation splitting the polar axis at 90 degrees to the Sun/Earth line. Cataloguers (and you all are cataloguers) with pretensions to being astronomers recognise the equinox as the motion of the Sun along an equatorial celestial sphere at 90 degrees to the polar axis. The poor cataloguer diverges from the astronomer in forcing an seasonal axial tilt component into the Equation Time whereas the correct and obvious factor is determined by shifts in orbital longitudinal orientation as constant axial rotation passes through it. So,in a few weeks I am the only person to enjoy the Equinox for what it is astronomically while cataloguers remain focused on seasonal changes. Probably there are a few here who would feel ashamed at ignoring an astronomical alignment and subsequently the further progress of that longitudinal orbital orientation in the Equation of Time correction in favor of a seasonal axial tilt one. |
