Looking at the contemporary graphic in the Wikipedia article which expresses how a location on Earth rotates to noon in 24 hours in order to justify the rotation to a star in 23 hours 56 minutes 04 seconds is shocking considering that the rotation of a location to noon has been known to vary in length from antiquity.The idea of the 24 hours of Monday elapsing into the 24 hours of Tuesday comes about via the noon correction which equalises the variations but people are willingly ignoring that such a correction is required. Yes, the diagram simplifies matters, so that they can be more clearly explained. It neglects the relatively small matter of the fact the Earth's orbit is an ellipse, in which the Earth moves with unequal speed, but makes that orbit a circle, so that the basic principle behind *one element* of the Earth's motions is brought out in isolation to be understood on its own. The 'leap second' represents the worst part of an error that has snowballed for the better part of 3 centuries for it represents the unauthorised hitching of axial and orbital motion directly to the horror of astrological geometry or rather the return of a star in 23 hours 56 minutes 04 seconds. Since the leap second has to do with an approximation to the 24 hour day, averaged out over a year, but now only slightly too short because it is out of date, what does it have to do with 23 hours, 56 minutes, 4 seconds? Precisely what sort of "authorization" is needed to express the Earth's motions in terms of uniform time, such as was calculated from the planets in Ephemeris Time, or which is produced by cesium atoms in Atomic Time? I assure you, the mathematicians and astronomers have produced accurate formulae which let them calculate accurate ephemerides. What further justification is needed? John Savard |

You are on the wrong side of a very simple set of principles which recognises that no two noon cycles are alike (hence the Equation of Time) and even it is frightening,at least in some aspects,to see that an idiotic and creationistlike understanding of the Earth's cycles be so dominant the good news is that the original principles which create the 24 hour day and its application to the daily cycle as a 24 hour/ 360 degree equivalency. http://en.wikipedia.org/wiki/Sidereal_time I do not mind your creationistlike defence of justifying the Earth's motions to a 23 hour 56 minute 04 second value but my goodness,even considering the sheer scale of the damage it does and in every possible way it does the greatest disappointment is that nobody finds the correct principles enjoyable,not just the 24 hour/360 degree equivalency but the Copernican reasoning from which it emerged. The 'leap second' represents the worst part of an error that has snowballed for the better part of 3 centuries for it represents the unauthorised hitching of axial and orbital motion directly to the horror of astrological geometry or rather the return of a star in 23 hours 56 minutes 04 seconds. Since the leap second has to do with an approximation to the 24 hour day, averaged out over a year, but now only slightly too short because it is out of date, what does it have to do with 23 hours, 56 minutes, 4 seconds? I still cannot account for why people would willingly ignore how the 24 hour day is created via variations in the noon cycle or rather adopt a dumb view which deterrmines that a location rotates to face noon in 24 hours - http://en.wikipedia.org/wiki/Sidereal_time Good kids who could easily grasp the treatise by Huygens are being indoctrinated into this awful way of treating the axial and orbital cycles and allowing for the fact that all here have be taught in the astrological style of Flamsteed there is no excuse for intelligent people to recognise that this 'sidereal' depiction of the Earth's motion is shockingly creationlike in content and character - Period Of Rotation "The actual value is 23 hours, 56 minutes and 4 seconds. This is the length of a "sidereal" day. It is the actual time it takes the Earth to rotate 360 degrees. The term "sidereal" (pronounced sigh-dear'- real) refers to the rotation of the Earth being measured relative to the stars. There ARE 24 hours in a "solar day". This is the time it takes from one noon (sun overhead) to the next noon. The difference in the two "days" arises from the fact that during a day the Earth also travels nearly a degree further on its yearly trek around the Sun." http://liftoff.msfc.nasa.gov/academy...ch/period.html When a website coming from Nasa determines that the Sun is overhead in 24 hours from one noon to the next in spite of the observation that no two noon cycles are alike how can good people standf a chance of appreciating the only technically correct set of principles leading to the creation of the 24 hour day,how these 24 hour cycles elapse seamlessly into each other and how it provides an equivalency between clocks and terrestrial longitudes and the daily cycle at 15 degrees per hour making 24 hours/360 degrees. Precisely what sort of "authorization" is needed to express the Earth's motions in terms of uniform time, such as was calculated from the planets in Ephemeris Time, or which is produced by cesium atoms in Atomic Time? There is no technical arguments to support the original error created by Flamsteed,specifically - "... our clocks kept so good a correspondence with the Heavens that I doubt it not but they would prove the revolutions of the Earth to be isochronical... " Flamsteed 1677 No astronomer or anybody using the title of doctorate would dare adhere to such foolishness which is why I am correct in stating that no astronomical authority exists at present. I assure you, the mathematicians and astronomers have produced accurate formulae which let them calculate accurate ephemerides. What further justification is needed? John Savard Mathematicians and astologers indeed !,a bunch of people who cannot even appreciate the basic principle which creates the 24 hour day and how it is applied to the axial cycle and terrestrial longitudes as a 24 hour/360 degree equivalency.It would be a lot easier to get the magnification guys interested in their true astronomical heritage and promote it to humanity by removing the cartoon conceptions of the Earth's motions created by Flamsteed and built on by Newton but even I have to concede that ,in the absence of any sense of responsibility,the indoctrination here goes too deep. |

It's true that Flamsteed wasn't quite right. The revolutions of the Earth are not absolutely uniform in time.

Compared to the regular solar day, which can move ahead or behind up to 15 minutes in the course of a year, the sidereal day *is* very nearly isochronous - in point of fact. Transit circle observations and the like have indeed provided solid proof that the Earth's rotation compared to the stars is highly uniform, unlike solar time which includes the effects recorded in the Equation of Time.

Our atomic clocks show that the Earth's rotation is slowing down, due to tidal forces from the Moon, in an imperceptible manner, and also there are variations due to the effects of seasonal winds, leading to the UT1-UT2 correction. The principles always remain the same whether it is pendulum clocks or atomic clocks insofar as the inviolate correlation which keeps clocks in sync with the axial cycle and terrestrial longitudes will always be 15 degrees per hour ,4 minutes for each degree of geographical seperation making 24 hours/360 degrees.To argue to the contrary ,and your entire community does this,assures that this is the dark ages of Western civilisation in so many ways. However, these effects are orders of magnitude smaller than the Equation of Time.

Transit circle observations and the like have indeed provided solid proof that the Earth's rotation compared to the stars is highly uniform, unlike solar time which includes the effects recorded in the Equation of Time. I am indebted to you for continuing to demonstrate just how awful the situation is ,where humanity and especially children are indoctrinated into an idea that the noon cycles are alike.The website of Nasa explaining the cult view which derives directly from Flamsteed - "There ARE 24 hours in a "solar day". This is the time it takes from one noon (sun overhead) to the next noon. The difference in the two "days" arises from the fact that during a day the Earth also travels nearly a degree further on its yearly trek around the Sun." http://liftoff.msfc.nasa.gov/academy...ch/period.html There is only the difference between the inequality in the noon cycle and it equalisation over an annual orbit to a human devised 24 hour day cycle.It is supposed to be the most fundamental astronomical timekeeping principle yet the cult idea believes that a location rotates to noon in 24 hours - http://en.wikipedia.org/wiki/Sidereal_time This is supposed to be shocking,an outrage and a mistake so obvious that in any other circumstances it would provoke the type of discussion that any individual could become involved in yet all that exists in one person trying to promote the correct ideals to a group that willingly sticks with a concept that would have puzzled our ancestors no end - the inability to grasp how the 24 hour days emerges from the variations in the noon cycle. It would be a lot easier to get the magnification guys interested in their true astronomical heritage and promote it to humanity by removing the cartoon conceptions of the Earth's motions created by Flamsteed and built on by Newton but even I have to concede that ,in the absence of any sense of responsibility,the indoctrination here goes too deep. .

We *understand* Newton and Flamsteed, and we know there is not, in them, the least contradiction to anything in Copernicus or Huyghens, just an amplification and a carrying further of their beautiful insights. The astrological geometry on which Newton hung his concepts is not supported by any observation insofar as the axial and orbital of the motions of the Earth do not correspond and cannot be justified by a 23 hour 56 minute 04 second value. Although all holocausts find their ideologies through individual doctrines, a holocaust is effectively a mass movement of people acting out an artificial set of principles without regard for a background heritage or where it is going,a blind monster that vandalises all ahead of it with no purpose only the perverse satisfaction of enjoying the power to do so. This particualr holocaust does have a distinct origin in 1677,a silly mistake made by one person who tried to justify the motions of the Earth using a clock and two external references - "... our clocks kept so good a correspondence with the Heavens that I doubt it not but they would prove the revolutions of the Earth to be isochronical... " Flamsteed 1677 I do not fault Flamsteed unduly but a mistake is a mistake and it did lead to the awful 20th century notions of time travel,warped space and other novelistic trash that serves no pupose but to highlight that something went badly wrong. You have stumbled over something in your understanding, so you fail to see this. But you do not explain yourself clearly enough even for me to see where your mistake is - or, if you *are* the one who is right, to make me see my mistake. John Savard |
