Second Attempt
Notice how carefully Oriel, over a period of some years, has avoided explaining exactly where his views and the views of other members of this group differ. He writes whole paragraphs - sometimes nultiple paragraphs - hundreds of times a year but refuses to explain something as basic as this. He also refuses to answer any questions designed to identify what the difference might be. As an example - Oriel, if you look due south at midnight on July 1st and again at midnight on January 1st of the next year will you see the same stars in the same places. Yes or no? |

"To set down in books the apparent paths of the planets and the record of their motions is especially the task of the practical and mechanical part of astronomy; to discover their true and genuine path is . . .the task of contemplative astronomy; while to say by what circle and lines correct images of those true motions may be depicted on paper is the concern of the inferior tribunal of geometers" *Kepler And the trouble is that the true and ideal path of the planets - not in an arbitrary sense of circular orbits, which Kepler disproved, but in terms of both their actual paths and the true causes of those paths - is now known, but this knowledge rests on the laws of gravitation, of mechanics, and of special and even (particularly in the case of Mercury) general relativity... all things you have rejected as empiricism, the opposite of contemplative astronomy. So you seek knowledge, but you spurn the very well from whence true, accurate, and dependable knowledge on these matters comes. And you wonder why so contradictory an action has made you a subject of ridicule. John Savard |

He disputes no facts as far as the simple situation of the naked-eye stars was as known to Galileo, so he will admit that the stars will be displaced about 180 degrees in relation to the poles in the sky between those viewings. Even if he does not deign to answer questions from those of us he holds in contempt for so savagely rejecting his great revelations. John Savard |

Even if he does not deign to answer questions from those of us he holds in contempt for so savagely rejecting his great revelations. Having, at an earlier stage in his presence on this newsgroup, engaged him in discussion, I have slowly and patiently worked out what his misconceptions appear to be. He accepts the Copernican model of the Solar System. He considers Copernicus, Galileo, and Kepler as great astronomers, worthy of our respect. Most of us see Newton as a worthy successor to those men; by providing a physical explanation for the motions of the planets as accurately described by Kepler, it was Newton that changed the Copernican system from a hypothesis people could choose, even with increased difficulty, to reject, to a hard fact that it would be madness to deny. However, Oriel sees it as an indignity to the heavens to explain the motions of the Moon and planets by the same physical laws as govern cannonballs on Earth - as an offensive insult to God, to explain the workings of His heavens by the rules which govern our hellish death- dealing instruments. That's what is at the root of his problem: he thinks with his *feelings*, and assumes that intuition (guided by some responsible hierarchy, i.e. the Catholic Church) rather than theory plus mathematics tested by experiment, the empirical scientific method, is the way to gain trustworthy knowledge. The other issues are minor in comparison. Basically, he sees the Solar System as having a hierarchical structure; thus, the Earth's rotational motion exists in relation to the Sun and the Earth's orbit around the Sun... and similarly the Moon's motions exist in relation to the Earth and the Moon's motion around the Earth. Trying to tie the Earth's rotation to the stars is... homocentric, sub- geocentric, and an illegitimate bypassing of the Solar System's chain of command! I mean, it's not as if the Sun was giving the Earth illegal orders, so that we had to relieve the Sun of its command... the Sun is behaving entirely in accordance with God's Law, so we have to accept the Earth's place in the hierarchy... or we'll get into the kind of trouble that the Silmarils got those Elves into! I suspect it will take an audience with the Pope to get him to see reason, and likely not even that. John Savard |

It is all a simple matter of definition. The only proportion that counts is the number of times the Earth turns daily for the equivalent number of times it makes a circuit of the Sun - I wouldn't say the proof using Sirius is trivial bit neither is it rocket science .As the sole star remaining in the brightness of the Sun,Sirius appears bright after the first 365 days/rotations and then slightly diminishes in brightness after the next 365 days/rotations as the 1/4 rotation's worth of orbital motion omitted in a year causes Sirius to drift back into the glare of the Sun,again in the 3rd year and by the 4th year after 365 days it is not visible at all.The extra day's worth of orbital motion brings Sirius back into view where the whole 1461 day/rotation process begins once more.There is no reason to diverge from the core system which connect the 24 hour AM/PM cycle to the Lat/Long system and certainly not for an unsightly imbalance between days and rotations derived from Ra/Dec reckoning as properly understood ,the reference system of the central Sun and Sirius is the only proper 'solar vs sidereal' foundation for timekeeping as long as days and rotations are kept in step. Once they declare that the Earth is no longer a good daily timekeeper and congratulate themselves on their hyper accurate watches - then what ?,all terrestrial sciences depending on the Earth's motions rely on an accurate relationship between rotations and orbital cycles and the arguments proposed to sever the ties between rotation and timekeeping are fatally flawed in this respect.Instead of dealing with a 'leap second' as something that was bogus to begin with,they take the catastrophic action of severing the ties with rotation altogether even though the Ra/Dec reckoning has the Earth spinning 1465 times in 1461 days !. People are better than this. |

I insist that none of this is in anyway difficult and yet it goes a
long way to undoing damage done previously,whether the community chooses to fix things is another matter and completely beyond the control of any one individual.The fact that Sirius doesn't appear after 4 consecutive years of 365 days opens up the explanation for why an extra day's worth of rotation and as the Earth moves around its circuit,brings Sirius back into view once more hence the observation that an orbital cycle takes 1461 days should reduce to trivia that there are 365 1/4 rotations per circuit and why the Ra/Dec reckoning is really based on the 365/366 rotation format - a subtle but importance difference. I feel the fear of exposure to ridicule is an illusion,they are already creating variants which try to bypass the celestial sphere conclusion and daily rotation for a more ambiguous view using the year 1820 as a foundation for rotation once in 24 hours so why the community doesn't just go directly to the core observations in antiquity to learn what reference belongs where and besides, the development of the calendar system and expressed in dynamical terms is such a thrilling read. |
