writes The same old BS. You will have to rely on your own commonsense in the absense of any worthwhile response and you need not go too far before you recognise why contemporary explanations are misleading and ineffective. To determine the annual orbital cycle as 365 day 5 hours 49 min you are required to determine the equable 24 hour day First whereby the equable hour,minute and second are determined as subdivisions of the 24 hour day. But the day is defined as the time between meridian passages of the sun, and it's divided up into hours, minutes, and seconds. In Civil Time the day is assumed to be of constant length. What's so difficult about that idea? If you agree that it is not possible to calculate the annual cycle without first determining the equable 24 hour day you will be half way to developing a far better appreceation of the calendar system as an offshoot of the principles which determine the equable day. Using the Sun as a reference for the motions of the Earth,the combined constant axial and variable orbital motion generates a change from one rotation for a given longitude meridian to the next complete rotation.The brilliance of our ancestors was to equalise the variation by adding and subtracting appropriate minutes and seconds to longitudinal noon to smooth out the variations and facilitate the seamless transition from one 24 hour day to the next 24 hour day,Monday into Tuesday,ect. This correction is known as the Equation of Time. In 1677,Flamsteed altered the 24 hour/360 degree equivalency and linked the rotation of the Earth directly to stellar circumpolar motion giving the value for rotation through 360 degrees as the sidereal 23 hours 56 min 04 sec.He screwed up the ancient exquisite reasoning that benefited humanity with the 24 hour day and subsequently the calendar year based on that equable day. Why not post the Flamsteed statement, or post a link to it? I'd be interested to hear from someone who actually knows what they are talking about, but AFAICS Flamsteed was responsible for the idea of the equation of time. BTW, either you have a virus or you are deliberately sending me unsolicited emails. -- What have they got to hide? Release the full Beagle 2 report. Remove spam and invalid from address to reply. |

To be fair to you,the mistake is a really old one and precedes the gravitational agenda (which makes use of the mistake) by a decade.The first professional astronomer was Flamsteed who set out to prove that the Earth rotates constantly on its axis through the motion of the fixed stars thereby making use of this observation for determining planetary longitude.

You can however appeal to those who are familiar with the equable 24 hour clock day,the Equation of Time correction from the noon determination and how one 24 hour day elapses seamlessly into the next 24 hour day by the 'Equation of Time' method but then you will encounter those who are aware that the precise value for axial rotation through 360 degrees,is and always will be 24 hours.

Flamsteed was incorrect. And just how was Flamsteed incorrect? The rotation of the Earth _is_ isochronical, to use Flamsteed's word, and we can now test it using atomic clocks and measurements to a fraction of a second in a year.. That experiment was a bit like the recent attempt to measure the speed of gravity - we are sure of the result but it needs to be tested. Why not post the Flamsteed statement, or post a link to it?

................ Initially, I was struck by an internet article which described how the second was originally defined as 1 / 31,556,925.975 of a year, and then after Scientists complained that this was not accurate enough, they re-defined the second as 1 / 31,556,925.9747 of a year. By definition, a (mean solar?) year is 31,556,925.9747 seconds in duratin. The question is, if 0.003 of a second made a difference to Scientists in 1967, then why was the "caesium frequency" of the current year only defined to the nearest 0.5 seconds? I have looked at formulae by Newcomb and others without success. For future reference, I note that I have made a few errors in the paragraph above. Apart from the spelling mistake, there are two others which should be corrected; 1967 - The atomic second was defined in 1967. I should have said 1956 when the second was re-defined as 1 / 31,556,925.9747 of a year, having been previously defined in 1954 as 1 / 31,556,925.975 of a year (the tropical year of 1900). 0.5 seconds - this should have read 0.05 seconds.
