Can you explain the bit about where "relativistic" fits into the EOT conspiracy please? DaveL You need to be intelligent to construct a conspiracy or a hoax,relativity is just plain dumb and for people who know no better,at least astronomically speaking.There is no reason to strain to 'understand' relativity and even those who have a casual interest in astronomy should be capable of sorting and sifting how the 24 hour day is defined off the variation in the natural day via the EoT or what amounts to the same thing - Newton's difference and distinction between absolute time and relative time. So let's put Albert's words front and center and then compare it with what Newton had to say,insofar as Newton is defining both a 'day' and the EoT via absolute time (24 hour day) and relative time (natural unequal day) http://bartleby.com/173/9.html From the website; " Now before the advent of the theory of relativity it had always tacitly been assumed in physics that the statement of time had an absolute significance, i.e. that it is independent of the state of motion of the body of reference." Now,Newton says no such thing,what Newton says is that there is no observed equable motion corresponding to the 24 hour clock even though it registers the axial rotation of the Earth through 360 deg.Surely you in the U.K. have not descended intellectually to the level where I have to explain again why the observed natural day is unequal for each axial rotation using the Sun as a reference and the EoT reduces the variation to an equality,in any case here is the appropriate passage which affirms there is no observed equable celestial motion corresponding to a 24 hour clock. "Absolute time, in astronomy, is distinguished from relative, by the equation or correlation of the vulgar time. For the natural days are truly unequal, though they are commonly considered as equal and used for a measure of time; astronomers correct this inequality for their more accurate deducing of the celestial motions. It may be, that there is no such thing as an equable motion, whereby time may be accurately measured. All motions may be accelerated and retarded, but the true, or equable, progress of absolute time is liable to no change. The duration or perseverance of the existence of things remains the same, whether the motions are swift or slow, or none at all: and therefore, it ought to be distinguished from what are only sensible measures thereof; and out of which we collect it, by means of the astronomical equation." Principia http://members.tripod.com/~gravitee/...tions.htm#time I assure you that Newton is correct and it appears ,at best,that Albert and by association his followers are not up to the job of commenting on Newton.If you wish to remove 'absolute time'/24 hour clock day from astronomy then be my guest but that Albert stuck you with the stellar circumpolar framework that emerges from linking the Earth's rotation directly to the sidereal value is a consequence of tampering with the EoT definition. To make it simple,here is what Albert foisted on you - http://home.t-online.de/home/sjkowollik/polaris.jpg |

Can you explain the bit about where "relativistic" fits into the EOT conspiracy please? DaveL Relativity is not conspiracy,it is just dumb salesmanship done at the expense of astronomy/astronomers in general and Newton in particular.If you cannot figure out why the pace of a clock is set to the 24 hr/360 deg equivalency for the axial rotation of the Earth it is hardly worth my while presenting relativistic texts which are unintentionally hilarious,even at a basic level. Within the borders below is something you posted on the perihelion of Mercury and predictions but you have to turn to the original 1920 explanation to appreceate the joke,even the first line where Albert foists Kepler's planetary laws on Newton is an assault on the eyes. __________________________________________________ ___________________________ He [Einstein] didn't "get lucky". He created a theory that made testable predictions. Those predictions have been shown correct to the precision we can currently measure. That's not to say another better theory won't come along in the future. For example Newton's theory of gravity is still quite capable of predicting most planetary orbits to high accuracy, with Mercury's being measurably altered in accordance with the predictions of general relativity. DaveL __________________________________________________ ____________________________ Here is what Albert had to say - " We must draw attention here to one of these deviations. According to Newton's theory, a planet moves round the sun in an ellipse, which would permanently maintain its position with respect to the fixed stars, if we could disregard the motion of the fixed stars, themselves and the action of the other planets under consideration. Thus, if we correct the observed motion of the planets for these two influences, and if Newton's theory be strictly correct, we ought to obtain for the orbit of the planet an ellipse, which is fixed with reference to the fixed stars" http://www.bartleby.com/173/29.html As you are a relativistic apologist I doubt you would get a chuckle out of that passage and especially the sidereal "motion of the fixed stars" but as for the rest of U.K. astronomy,I guess you should all take up stamp collecting, gardening or use your telescopes for birdwatching.Whatever Albert wrote in that passage above, it certainly is'nt astronomy and those who followed him certainly cannot call themselves astronomers. Perhaps you can tell others what "influence" stellar circumpolar motion has on planetary motion but as for me,I will just enjoy the joke alone. |

out of that passage and especially the sidereal "motion of the fixed stars" but as for the rest of U.K. astronomy, I ask again, what is the relavence of relativity to the equation of time? And please don't just cut and paste your previous answers, they aren't relavent to the question. DaveL |

And please don't just cut and paste your previous answers, they aren't relavent to the question. DaveL Newton wrote this astronomical definition and distinction between absolute time and relative time in terms of the Equation of Time. "Absolute time, in astronomy, is distinguished from relative, by the equation or correlation of the vulgar time. For the natural days are truly unequal, though they are commonly considered as equal and used for a measure of time; astronomers correct this inequality for their more accurate deducing of the celestial motions." Principia With the Horizon 'time travel' documentary on BBC this evening,you would do well to first look at the longitude problem and the development of accurate clocks as rulers of distance in association with Newton's accurate description of the difference between a variable natural day (relative time) and a constant 24 hour day (absolute time) before you go chasing relativistic 'time travel' rainbows. Again,absolute/relative time is a wonderful astronomical twist to the longitude problem that men have yet to appreceate and I assure you that it is all historically documented.Albert defined absolute/relative time to his own liking but these terms are astronomically definite and accurate components of the EoT in terms of the difference between the natural day and the clock day.If you are not capable of comprehending what the EoT is and what it does you and your relativistic colleagues are not competent to astronomically deal with with those passage in the Scholium IV of the Principia where absolute/relative time,space and motion are presented . http://members.tripod.com/~gravitee/...tions.htm#time If you can't figure out why the pace of the 24 hour clock is fixed longitudinally to planetary coordinates based on 360 deg with the prime meridian at Greenwich you are unlikely to understand how Harrison clocks solved the longitude problem. |

Can you figure out why my watch, fixed to 360 degree rotation goes round 366 times in a year while my ordinary watch goes round 365 times? Perhaps ordinary watches aren't fixed to 360 degrees per 24 hours. Unlike those who immediately say that a topic is difficult to comprehend,I contend that men do not think the topic through carefully enough and it is laziness rather than intellectual incapacity which destroys reasoning.In this case,you have to define a 24 hour day first before you divide it into an annual cycle.You may miss the subtle difference above even if the development of accurate clocks by John Harrison relied on the 24 hour/360 deg equivalency using the Sun as a reference makes a pretty big field of discussion unfortunately it appears that your watch with its 24 hr/1440 min/86 400 sec subdivisions just popped into existence. The admiration for astronomers,navigators and inventors stretching back to remote antiquity and the principles by which they allied planetary geometry with astronomical observation alone makes the longitude story worth investigating and even if the purpose of the EoT is lost to history,it amounts to a serious deficiency and lapse in contemporary thinking that makes us appear brutes.Anyone who watched the Horizon program will have noted the hatchet job done on Newton's 'absolute time' so geeks could talk of utter rubbish,in case you do not know by now that absolute time and relative time refer to the difference between the variable natural day and the equable 24 hour day via the EoT,I repeat the relevant astronomically significant passage from Newton. "Absolute time, in astronomy, is distinguished from relative, by the equation or correlation of the vulgar time. For the natural days are truly unequal, though they are commonly considered as equal and used for a measure of time; astronomers correct this inequality for their more accurate deducing of the celestial motions. It may be, that there is no such thing as an equable motion, whereby time may be accurately measured." Principia Those who built the clock system allied with the Earth's geometry and geography were aware that there is no motion corresponding to the 24 hour/360 deg equivalency for that is why the EoT is required and indeed Newton is only confirming what was already known for centuries.The program last night on BBC made it appear that there was nothing but superstition before Newton and the geek said so but if viewers wish to have their intelligence insulted then fine. Newton's use of the word relative sounds like, but is different from Einstein's and from mine. When I say relative I mean a varied selection of people, most to be avoided at all costs. Burying your stiff upper lip in the sand I would say.Be as ambiguous as you wish but Newton's EoT difference between the natural day and the 24 hour clock day is a definite astronomical observation,Albert's and your's is an ambiguous mess which conceals rather than reveals anything.As much as the U.K. astronomical and maritime heritage developed from the principles of clocks and their association with geometry and astronomy I refuse to believe that the pride of a nation would sink using simple liguistic tricks. Christmas tends to be a relative time, a time that goes very slowly indeed, probably based on a 1000 degree rotation, a time to be avoided, a time to hide behind the sofa, a time for hibernation, a time to say goodbye to you, dear Gerald. You are getting nowhere but fast. ----------------------------- Martin Frey http://www.hadastro.org.uk N 51 01 52.2 E 0 47 21.1 ----------------------------- I do not need to go anywhere,the development of accurate clocks in tandem with the EoT is a historical and well documented fact and especially the 24 hour/360 deg equivalency for the axial rotation of the Earth.If you decide that the pace of a clock fixes the Earth's 360 deg rotation to the sidereal/stellar circumpolar motion as the RGO does you will have descended from one of the most enlightened people to the dumbest race ever to set foot on the planet,that is not an insult and no offense is intended but if others wish to have their intelligence insulted by the hatchet job done on Newton,that is a fact. The Lat/long coordinates in your signature also represents a unique time coordinate off the Greenwich longitude meridian,by reducing the determination of natural noon to the planetary longitude coordinates via the EoT you can determine your distance to Greenwich or anywhere else,simple historical fact based on the fact that the pace of a clock is fixed to axial rotation in 24 hours/360 deg. |

Harrison devised a mechanism. It could be adjusted to tell time with 59 minutes to the hour, 23 hours to the day, 3 periods of daylight to the day and 6.798754 days to the year. Or, as he intended, adjusted to whatever provided the most practical utility. You confuse the division of the equator into 360 degrees (which keeps to the 24 hour 360 degree equivalency) with the rotation of the earth through 360 degrees which most definitely does not. If it is 10 am in London then it is 10 pm in the antipodes. 100% accurate. But this has NOTHING to do with the rotation of the Earth. It is very easy to mistake stupidity for profundity. You should, at the very least, consider the possibility that you have made this simple error. you will have descended from one of the most enlightened people to the dumbest race ever to set foot on the planet,that is not an insult You could have fooled me. ----------------------------- Martin Frey http://www.hadastro.org.uk N 51 01 52.2 E 0 47 21.1 ----------------------------- |
