The return of a star being constant, in units of time derived from a mechanical clock, shows that _something_ about the Earth's motion can be naturally measured by mechanical clocks. Since a mechanical clock is a simple system, using the simple motion of the Earth as a starting point does not do "damage", it gives us a solid place to stand to begin explaining the complexities of the natural noon cycle, which has the variability of the Equation of Time in it. If we combine the Earth's orbital motion with this view of the Earth's rotation, we see how the Earth's orbital motion yields the Equation of Time. Yes, our customary unit for the dials of mechanical clocks comes from averaging the solar day. This is a convenience. But we could have started with a timekeeping unit based on a pendulum clock with a pendulum exactly one foot long, and found the return of a star was constant by such a clock - so your apparent objection that the solar day must be the starting point, and going from the average of the solar day to the return of a star and then going back to explain the solar day from it is circular reasoning is not really valid.

A person who cannot grasp the basic references for the daily cycle and how the variations in the natural noon cycle correlate with *24 hour/ 360 degrees and the information which contains planetary shape and rotational characteristics is no teacher and no astronomer - period !. But... but... but... this EXACTLY describes you! You just cannot grasp the basic reference for the daily cycle, you cannot grasp the concept of frames of reference, you cannot grasp the concept of the Sidereal day, or the analemma, or a score of other well-established truths about celestial mechanics. It is YOU who is no teacher and no Astronomer in these forums... and everyone knows this but you - period! I feel you are all *behaving like spoilt children which is why it is becoming unbearable here. Well, if you can't stand the heat, get out of the kitchen... I for one would not miss you at all, because you are apparently unteachable, you hate being corrected, you are always defensive and argumentative. Your arguments are weak and I find myself disappointed by your consistent failure to follow through on any promising lines of inquiry. You repeat yourself over and over again. You have been given detailed explanations about how and why you are wrong, but you choose to view any peer evaluation with cold disdain. I can't remember a single instance where you have acknowledged or otherwise thanked anyone here for teaching you something you didn't already know. In the end, there is not much to be gained be trying to teach a pig to sing, it just annoys the pig and wastes everyone else's time. The return of a star does not proved daily rotation is constant,it shows that a star returns in 23 hours 56 minutes 04 seconds based on a 24 hour timekeeping average *within the framework of the 365/366 day calendar system. So... what DOES the return of a star in 23:56:04 tell you? It certainly must mean something, doesn't it? It doesn't have anything at all to do with the 24 hour solar day except for the similarity in length. If the Earth was in a much smaller orbit, for example, and would therefore move faster along that orbit, then the Sidereal Day and the Solar Day would not be so comparable in length. Think about it.

You never answered the question - no surprise there - *that being "what significance DOES the return of a star in 23:56:04 have?" Clearly it must mean something... even to you. It takes two qualifiers,both based on timekeeping averages,to explain the constant return of a star in 23 hours 56 minutes 04 seconds.The value means nothing in terms of planetary dynamics no more than the wandering 'analemma' Sun does based on the average 24 hour day,it does show the danger of using timekeeping averages to model planetary dynamics and solar system and universal structure while as an observational convenience in its Ra/Dec mode,it is excellent. There are excellent tutorials giving the basic outlines which links clocks to the daily cycle and planetary geometry and geography even if they do not get into the type of detail which Huygens goes into or my additions explaining the planetary dynamics behind the natural noon variations - http://www.youtube.com/watch?v=iF85O9SJCaE Most here probably consider themselves intelligent but in this matter I have yet to see anything but a sort of indoctrination.Now,it is not the value but the actual means by which the 24 hour/360 degree value is arrived at in order to move the material into a more productive mode. Sincerely,if you wish to consider me mad for believing the Earth turns once in 24 hours or 15 degrees per hour then leave it at that,all the historical and technical details support the reasoning behind that value while the 'sidereal time' has a definite beginning with Flamsteed.

It's true the Sun doesn't have a real motion corresponding to the analemma. It would, however, have to have such a motion if the Earth rotated once in an average 24 hour day. I've pointed out the flawed logic behind your "two qualifiers" statement - you may think that astronomers are using circular reasoning, but they could have started with a mechanical clock whose unit of time had no relationship to the day. So the dependence on the timekeeping average of the solar day is only illusory. If people consider you "mad", it is not because you find the idea that the Earth rotates in 23 hours and 56 minutes, instead of in 24 hours, to be strange. Many people find it strange at first when introduced to astronomy. But your unwillingness to accept simple and patient explanations, to engage in substantive discussion, your determination that you must know better than generations of people the world has recognized as astronomers... these are the things that truly leave you open to criticism.

I've told you many times before, I fully agree with you that the Earth turns 15 degrees per hour each 24 hours, totaling 360 degrees, WITH RESPECT TO THE SUN. We do not disagree here. Flamsteed knew this, too, but he also noted that with respect to the stars the rotation only took 23:56:04. Both observations are legitimate because they reference different frames. What is so hard to understand here? There is really nothing strange about these observations, nothing mystical or magical, they are what they are, and the subsequent model that was created to explain these timings does a magnificent job.

That is incorrect,the natural noon cycles are unequal and there is no external reference for independent daily rotation through 360 degrees in 24 hours,it is a quirk of how the average 24 hour day is transfered to daily rotation as a constant after the Equation of Time is applied to natural noon as one 24 hour day turns into the next 24 hour day then so is rotation kept constant. I am satisfied that the message is finally getting through where it matters and can leave you and the rest to sort things out among yourselves in creating whatever story you like based on 'sidereal time'. \Paul A |
