I use the terms 'numbskulls and freaks' because there is nothing remotely difficult in gauging the natural noon cycles are unequal even though you people,rsadly representing the major institutions, believe it is 24 hours exactly - '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." http://liftoff.msfc.nasa.gov/academy/rocket_sci/orbmech/period.html Maybe you wish to compare that Nasa statement with that of Huygens - Here take notice, that the Sun or the Earth passeth the 12.

It doesn't matter if you choose sidereal or terrestrial time to refer to; the rotation of the earth in either case is irregular at a fine scale and slowing at a larger scale. In any case, you cannot accurately reproduce the SI second by measuring the rotation of the earth, equation of time or no, and a leap second is required to keep any time scale which refers to noon, sidereal motion, or any other measure related to the rotation of the earth in synch with any time scale based on quantities believed to be constant and repeatable.

But while there are errors and oversimplifications on many web sites, and in many standard reference works, concerning the motions of the Earth in the heavens, it does not seem to me that they are truly the source of the objections you are making. Instead, I am afraid that the impression you give is that your disagreement is based on the following premise: Time is what you get from a sundial, not what comes from a mechanical clock. Thus, the mistake of Flamsteed and Newton is that they put the time from mechanical clocks first, not necessarily that they got the wrong answers. So, when Flamsteed referred to the Earth's axial rotation as "isochronous" because the return of a star happened every 23 hours, 56 minutes, and 4 seconds by a mechanical clock, he by implication termed the Earth's natural time cycle as deficient, and praised mechanical clocks as superior to the Sun. Huyghens, in his explanation of the Equation of Time, made no such mistake: he clearly explains it as a correction to the approximate time indicated by a mechanical clock, to enable one to obtain the real time. This is a premise that will not be accepted by astronomers. Newton did successfully show that the heavens *can* be understood by the laws which govern moving bodies on the Earth. So we start with simple regular time in order to disentangle the behavior of natural physical systems. After all, for example, the orbit of Mars is more strongly elliptical than that of the Earth, and its relation to the direction of the tilt of Mars' polar axis also differs, so a different Equation of Time would apply to Martian sundials. While nobody lives on Mars yet, it is already apparent that there is no reason to pick Earth's sundial time instead of Mars' sundial time - and every reason to use regular clock time as a starting point to understand the Universe. And there seems to be a second premise too, I'm afraid. Since you apparently don't understand calculus and other advanced mathematics, you seem to have concluded that when scientists do use these things, they're just engaging in a con job. Well, I'm sorry, but they *do* know what they're doing. John Savard http://www.quadibloc.com/index.html

But this was not a circular definition, because this time scale, as given by mechanical clocks, already existed. We cannot, of course, change or control time (aside from time dilation, of course); but we can, legitimately, choose which time scale is useful or interesting to us. We live in a mechanized society; this may be deplored for some reasons, but that has meant that for us the most practical time scale is the one in which the uniform rotations of our turbines and dynamos are most naturally measured.

The existence of clocks was in principle irrelevant for Newton. As it is to us who have taken over Newtons viewpoint, with 'Newton's laws' replaced by 'the laws of physics'. Pendulum clocks (and atomic clocks too) can't indicate true time by themselves. Many corrections must be applied in order to interpret their readings properly. Which corrections are the 'right' ones follows of course from Newton's insight. > We cannot, of course, change or control time (aside from time dilation, > of course); but we can, legitimately, choose which time scale is useful > or interesting to us. We can of course choose any time scale, but we should recognize that on favored time scale exists, viz the one in which the laws of physics take their simplest form. And that is precisely where our dear troll fails. > We live in a mechanized society; this may be > deplored for some reasons, but that has meant that for us the most > practical time scale is the one in which the uniform rotations of our > turbines and dynamos are most naturally measured.

For your amusement: Shortly after all this the differential was invented (like you still have in your car) Some 18th century clocks had differential gears to subtract/add the time correction, and two minute hands. One indicating the true clock time, the other solar time. Lacking time standards in those days the solar hand was useful for setting the clock to sundials or noon guns. Even our troll should like to have one, Jan

Well, you've finally done it. You have provoked me beyond all endurance! I have now added to my web page, at the location http://www.quadibloc.com/science/eot.htm a page explaining the Equation of Time as its causes are currently understood by conventional astronomers. Unfortunately, I have to *begin* explaining it with the "sidereal day" you object to, because the cause of the days being unequal is that, while the rotation of the Earth does not vary, it happens that the Sun is not exactly (in the direction from the Earth) where you might expect to find it in order to convert the sidereal rotation period of 23 hours, 56 minutes, and 4 seconds into the equal 24 hour day.

Tommorrow is just another working day for me as it is for many here,it begins early and ends late notwithstanding the enormous responsibility that follows in undoing the damage to astronomy in the name of lazy and incompetent creatures. Children ,at least teenagers, can now understand how the 24 hour day is created from the observation that the natural noon cycle is unequal,how men equalised it to a 24 hour day and how each of these 24 hour cycles elapse into the next 24 hour cycle. Teenagers can then approach the topic of how accurate clocks were invented to maintain the standard pace of the 24 hour cycle for long periods as a means to determine terrestrial longitudes.By exploiting the Equation of Time principles which create the 24 hour cycle,brilliant minds transfered the average 24 hour cycle to the axial cycle and treated it as a constant,the facility which allowed one 24 hour day to elapse into the next 24 hour day keeps clocks in sync with the axial cycle at 24 hours/360 degrees where 4 minutes of clock time represent 1 degree of geographical seperation making 24 hours span the globe. Astronomy needs heroes and they will come from genuine and good people,particularly teachers, who have enough intelligence to appreciate how the 24 hour day was created from observing the inequalities in the natural noon cycles over an annual cycle and when Copernicus discovered the axial cycle,how the old Equation of Time principles were overlaid on terrestrial geography as a 24 hour/360 degree correlation. That nonsense of believing that the natural noon cycle is 24 hours in order to use the return of a star to justify the motions of the Earth is for unintelligent people - http://en.wikipedia.org/wiki/Image:Tiempo_sid%C3%A9reo.en.png Some day kids will not have to suffer 'sidereal time' rubbish just because of the pretension of mathematicians who have no feel for astronomy,its methods and its insights or people will eventually see just how eaily understandable structural and timekeeping astronomy actually is.I have done my part now it is time for others to come off the fence.

In this connection, it might be noted that I have just added to my page at http://www.quadibloc.com/science/eot.htm an additional illustration showing that, since when drawn to scale, a circle representing the Earth's orbit around the Sun is a circle to one part in 7000, but the distance of the Sun from the center was large enough to depict, I drew my illustration of the working out of Kepler's Laws using a first-order approximation that would be fully accurate on that scale, rather than write a program to calculate the orbit... and the technique I used was uniform motion viewed from the "equant" on a "deferent", taken straight from good old Ptolemy.

From that > point of view, gravity is as "nonexistent" as the centrifugal force. . Ah, but we begin with gravity being real, and from the viewpoint without general relativity, centrifugal force is clearly distinct; it is felt because a body moving in a circle needs constant acceleration; it violates Newton's Laws. General Relativity merely obscures the distinction between the two cases, so this elevates the dignity of the ficticious forces. Gravity still has mass as its obvious cause in both systems. > > Of course, leaving out GR, SR, and QM is something I can hardly call > > lying, so tiny and remote they are. > > How and why does a transistor work? > > Nowadays, a lot of people usually carry millions of transistors with > them almost all the time, so they're hardly remote. So please explain > - without using QM, and of course without lying.... ;-) Let us say we have a system in which a great deal of water must flow through a grating, but this water carries with it small amounts of impurities which will not go through the grating. In that case, after the impurities build up and block the grating, it is much easier to take the obstruction out of the way than it is to carry the large quantity of water from the one place to another by other means. In an NPN transistor connected in the "common emitter" arrangement, a small current allowed to flow out of the base of the transistor acts like the removal of twigs and leaves piled up against a grating, allowing current to flow from the collector to the emitter - or electrons to flow from the emitter to the collector. It would take quantum mechanics to explain the reasons why the different elements behave the way they do, leading to the Periodic Table of Elements, also known as the roundaround board of the firststuffs. But to see how a transistor works, we do not need to go into all the details. In the atom, a certain number of positive particles called protons are in the center, or nucleus. They are usually accompanied by neutrons, except in the element with only one proton in the center; these have no charge, but help to provide a nuclear force which holds the nucleus together in the face of the repelling like positive charges of the proton. Orbiting the nucleus there are electrons, attracted to the nucleus by opposing electrical charges like planets are attracted to the sun by gravity. But quantum mechanics, again, makes the picture more complicated. Only the consequences need concern us here. While an atom contains equal numbers of protons and electrons, there is a weaker force which leads to the last few electrons on an atom on the left side of the periodic table being less strongly bound, and which leads to atoms on the right side of the periodic table feeling a need for more electrons. But this effect (called the van der Waals force) is smaller than the electrostatic force which demands the number of electrons equal the number of protons. Thus, we get such things as the salt molecule. A sodium atom, with a weakly bound last electron, gets together with a chlorine atom, which feels a need for an extra electron, and partly shares that last electron with the chlorine atom. Because the two stay close together, the molecule is not ionized; electrostatic force is satisfied, positive and negative charges stay balanced, but the last electron can edge a bit closer to the chlorine atom, minimizing the combined potential due to the van der Waals force and the electrostatic force. In a semiconductor, we have an element like silicon, with four out of eight electrons in its outermost shell; that is, it is in the middle of the periodic table; unlike an inert gas, it is not satisfied with its configuration, but it could accept four electrons, or give four electrons, with equal benefit. (This is an approximation; we have quartz, with oxygen atoms linking silicon atoms, but diamond, with carbon atoms linked directly, and fluorine is more violent than chlorine, but lithium less violent than sodium, because the size of an atom as it grows tilts things towards giving electrons away as well.) To make the N-type region of a transistor, we add small quantities of an element willing to give away an electron, such as gallium, and to make the P-type region of a transistor, we add small quantities of an element feeling the need for an electron, such as arsenic. Metals, which are elements willing to give away electrons, can also coalesce in a crystal where the extra electrons freely move about with independence from the individual atoms, and these conduct electricity as well. Adding even a small amount of gallium to silicon makes it a better conductor. While a chunk of sulfur, on the other hand, for example, is no conductor of electricity, because its atoms tend to join in small molecules, a small amount of arsenic in a silicon matrix behaves like the inverse of a metal, where "holes", absences of an electron, move about freely, carrying positive charge. The silicon imposes a metal- like structure, so the P-type dopant conforms to that structure, leading to an inverse model of metal-like structure. When an N-type region and a P-type region are two parts of the same chunk of silicon, so they are intimately connected, both parts conduct electricity, but at the barrier between them, electrons can easily flow from the N-type region to meet holes from the P-type region and cancel out with them. But this boundary is not a good place to expect electrons to come from into the N-type region and holes to come from into the P-type region. So you can make a diode. The metal wires merely clamped on to the outside of the semiconductor are connected less intimately, so an unending replenishment of electrons or holes is possible from them. An NPN transistor is made like this: a chunk of silicon is mostly N- type, doped with gallium. But that N-type area is divided into two parts by a very thin layer doped with arsenic, being P-type. Electrons can flow from one N-type area (the emitter) to the other N- type area (the collector) with reasonable ease, but a few get stuck in the wrong-way diode path from the P-type area in the middle (the base) to the collector. Those that get stuck lead to a positive charge on the collector side and a negative charge on the emitter side, blocking the flow of electrons through the transistor. But just allow some electrons to drain out of this area, by applying a tiny positive signal to the base, and the large flow of electrons from emitter to collector once again surges through! Hence, the transistor amplifies. I *allude* to quantum mechanics to avoid lying, but I do not *use* it; I do not use Schrodinger's Equation, or go through the p-type and d- type and s-type orbitals and exhibit their shapes as solutions to a differential equation.

Well, that is true, in a manner of speaking. Looked at from outside the rotating system, to make something go around in a circle, you have to pull it from its natural straight-line motion; what it "feels" is its inertial resistance to your "upwards" pull, and the "downwards" centrifugal force is a fictitious force. Of course, the Principle of Equivalence in General Relativity can give us another way of looking at things, in which even non-inertial frames are of equal dignity, so that the distinction between the real force of gravity and the fictitious inertial forces is moot. Of course, leaving out GR, SR, and QM is something I can hardly call lying, so tiny and remote they are. John Savard

To be simple due to ignorance is not blameworthy; those who are ignorant but fail to realize it are the ones who are annoyingly stupid. Having an incomplete education is definitely a way to convince oneself that one is not ignorant. But it is actually quite difficult for people educated in mathematics or the physical sciences to get into this kind of condition. That is because these are not subjects learned by rote memorization. One has to understand the concepts for oneself in order to do practical work with them. Scientists get their hands dirty in the laboratory; so, today, it would be as hard to teach a false theory of science on the basis of authority as it would be to try and teach wrong ideas in schools of carpentry. That which is not the truth will fall down in practice. Copernicus and Huyghens are respected and honored today among astronomers. But Flamsteed and Newton are also honored as well; by taking the step you criticize, putting the uniform time of the mechanical clock first as the true standard of time, and relegating the solar time of the sundial to the status of a local peculiarity of the Earth's particular scheme of motion, contrary to what was *then* everyday experience (though fitting well to today's experience) they opened a door through which scientists had to pass in order to further their understanding of the Universe. In fact, even Ptolemy used the Equation of Time to go *from* sundial time *to* uniform time because uniform time was needed to account for the motions of the Moon. Today, we live by clock time, so we don't have to involve sundial time. If we are interested in the subject of solar time, we will go from uniform time to solar time. And this is why, when some astronomers explain why stars return after 23 hours, 56 minutes, and 4 seconds, they go straight from the length of the year and the average 24 hour length of the day to obtain the length of that period - without pausing to mention, because it is a separate topic, the Equation of Time. They oversimplify to avoid seeming pedantic; they do not mean to decieve or confuse. But other astronomers will be careful enough to give a passing mention to this detail. John Savard

I have spoken often enough with incredulity of people who do not recognise that the daily cycle is unequal (hence the Equation of Time) and believe that a location rotates to noon in 24 hours exactly even when people like Christian Huygen's treatise explicitly shows the difference between the natural unequal cycle and the human devised 24 hour cycle. - http://www.xs4all.nl/~adcs/Huygens/06/kort-E.html If you live by 'oservational evidence' then so shall your concepts fall by it,in this case the belief that a location rotates to noon in 24 hours - http://en.wikipedia.org/wiki/Image:Tiempo_sid%C3%A9reo.en.png In truth,it is always going to be about genuine people who can become familiar with the Equation of Time correction which reduces the unequal noon cycle to an equable 24 hour cycle and educate children in the enjoyable principles which keeps these days ticking over into each other.I look at your unintelligent 24 hours/361 degrees as nothing but a bad era for humanity and astronomy and it is about time others spoke out on this very important matter.

How many of your kind tried to disturb the simple faith of people by proposing yourselves as authorities in astronomical affairs while failing in even the most basic principles. I think you need to hear the sweet music which carries people through dark episodes in human history such as this one where a once vibrant astronomical heritage withered in the hands of dull men - http://www.youtube.com/watch?v=cxqylxfYyQM It sometimes happens that great minds come back to simple things and set aside the pretension that attaches itself to existence .Oscar Wilde knew it and expressed it in a lovely way known to all Christians - I"Like all poetical natures he loved ignorant people. He knew that in the soul of one who is ignorant there is always room for a great idea. But he could not stand stupid people, especially those who are made stupid by education: people who are full of opinions not one of which they even understand, a peculiarly modern type,summed up by Christ when he describes it as the type of one who has the key of knowledge, cannot use it himself, and does not allow other people to use it, though it may be made to open the gate of God's Kingdom.." Oscar Wilde The gate to understanding the great astronomical insights is opened by the generosity of the human heart in respecting the achievements,and sometimes the failures,of our ancestors.. 'Abide With Me' is as much an invitation to a level of understanding which produced the great timekeeping and structural astronomy as it is to the great Christian sentiments or anywhere the endeavors of men take them.

To be fair, you have shown us some examples of web sites and other sources that explain the 23 hour, 56 minute, 4 second axial rotation of the Earth by starting with statements that imply that a solar day is always 24 hours exactly. This, however, is simply an error, or an oversimplification to delay explaining the Equation of Time until later. Astronomers do not claim the solar day is 24 hours exactly, and any textbook on positional astronomy, for example, will show you that the Equation of Time is still understood by those who are called astronomers! > To think that > any person would vandalise an exquisite set of principles such as the > 'Equation of Time' that renders the equable 24 hour day cycle from the > inequalities of the natural noon cycle would be unimaginable yet that > is eaxactly what you do - . > http://en.wikipedia.org/wiki/Image:Tiempo_sid%C3%A9reo.en.png . This is one of those examples. It should have been "mean solar day" and "sidereal day", not "solar day" and "mean sidereal day". You have made typographical errors in your posts too. Don't judge the astronomical community by a typo! > It is not your ignorance and those like you that concerns me but > rather the lack of courage in those who should know better . . There's nothing for them to be courageous about, because the official astronomical community has _not_ got it wrong! Millions of amateur astronomers have a sufficiently clear understanding of the concepts behind the Earth's motions in the heavens that no conspiracy to obfuscate or distort them could possibly get off the ground! On the other hand, some of what you object to isn't going anywhere - because it doesn't have to do with the phenomena, it has to do with how we look at them. We take the time from our mechanical clocks, even though they were devised by our own hands, as the basis, and the time a sundial shows as something that is derived from it as a consequence. As you correctly note, Copernicus and Huygens didn't do that; but Newton and Flamsteed started the habit. This is because uniform time _is_ present within the laws of nature as we have found them through our studies. The Earth's axial rotation _is_ uniform, like the motions of the clocks, and human beings neither set the stars in the skies, nor started the Earth spinning. Kepler's laws show how the Earth will move, measured in uniform time, around the Sun, and these, plus the Earth's uniform axial rotation (yes, that bad old 23 hours, 56 minutes, and 4 seconds), plus the tilt of the Earth's axis *give* us the varying time a sundial shows us. What might have been backwards reasoning at one time, from the hypothetical and invisible to the everyday visible fact, is now clear and forwards reasoning, because we are used to mechanical devices and their uniform time scale. > The way > the average 24 hour day was transfered to the axial cycle as > 'constant' in order to create the inviolate 24 hour/360 degree > correlation should be the pride of any thinking person but it just has > not happened here,not even with the principles of Copernicus and > Huygens present.

Education consists in telling half-truths (or even outright lies) to avoid complicating things too much for the pupil. In the next stage a fuller version of the truth may be told. And so on. The trouble with our troll seems to be that he remained stuck in an early stage of the process, and refuses to learn more. Best, Jan "Centrifugal forces don't exist!" (high school physics teacher)

If people are being barred from contributing to astronomy because their parents are poor or do not come from aristocratic or well- connected families, this is an injustice to be fought. But if people are barred from careers in the sciences because they're not smart enough to understand first-year calculus, it may be sad for them, but there's not a thing that anyone can do about it. The "scientific priesthood" that enshrouds the motion of the bodies of the solar system in a web of complication exists only in your imagination. My web site at http://www.quadibloc.com/science/eot.htm explains the Equation of Time in terms of... the axial tilt of the Earth compared to its orbit (which is real, and does cause the seasons, but which does not "vary" in the course of a year); the elliptical orbit of the Earth with a varying rate of motion, following Kepler's laws; the annual motion of the Earth around the Sun once a year; and the uniform rotation of the Earth on its axis, which, when considered in itself, and not in terms of the Earth's relation to the Sun, does indeed have a period of 23 hours, 56 minutes, and 4 seconds. The stars make a 360 degree circle around the Earth and the Sun, and so both the 23 hours, 56 minutes, and 4 seconds of a rotation of the Earth, and the 365 and 1/4 days of a revolution of the Earth around the Sun correspond to 360 degrees - as *well* as the 24 hours of a solar day, since at any one moment, the 360 degrees of the Earth correspond to all 360 degrees of relationship to the Sun, giving all values of local solar time of day. I have quite scrupulously checked my page to avoid the errors and oversimplifications that you have objected to in some other places that discuss these things, but the page is in terms of conventional astronomy - because it is right, and it works. The whole world is not out of step, with you the only one who knows the truth. John Savard

A civilisation which cannot accurately promote how the 24 hour day originated astronomically and how they elapse into each other via the Equation of Time correction can hardly be called a civilisation.It just happens that you and your kind believe that the noon cycle is 24 hours exactly in order to justify the motions of the Earth to the return of a star to a meridian - http://www.nmm.ac.uk/server/show/nav.00500300l005001000 The problem of global warming pales in comparison to the intellectual standard which dominates celestial/terrestrial investigations yet the same people who cannot grasp the basic axial cycle of the Earth will be influencing political decisions in resopect to global climate,a discipline heavily dependent on the motions of the Earth.Now you want to know what our fate is, but that is all dependent on the courage of individuals who have a shread of appreciation into what goes into that standard pace of a clock hand you see day in and day out.

The additional information linking clocks to the axial cycle and terrestrial longitudes via the Equation of Time correction and the 24 hour/360 degree correlation is now here for all to enjoy - http://www.xs4all.nl/~adcs/Huygens/06/kort-E.html The opportunity to set things right is there for any individual who finds himself/herself on the right side of the argument,in this case the observation that the duration of the noon cycles are unequal as opposed to the false 'sidereal time' view that they are equal. Global climate and the motions of the Earth are linked in an intimate way and I assure you that working with the correct dynamical principles of axial/orbital motions alters the way global climate and the seasons are approached as people will soon discover. So Sam,I appreciate that you normally do not respond to threads and yet you are left to try and make an argument for the guys in this forum who have conveniently disappeared and even if your creationistlike attitude to the daily cycle is unintelligent,at least you are trying.As I have little regard for your 'sidereal time' dynamics for the motion of the Earth it remains only to express a little sadness for sheer loss of human effort before turning to the matter of recovering heliocentricity and the principles which keep clocks in sync with the axial cycle as 24 hours/360 degrees.

" > > http://liftoff.msfc.nasa.gov/academy/rocket_sci/orbmech/period.html When they say "There ARE 24 hours in the 'solar day'", they are not trying to claim that sundials keep exact clock time. The problem is, instead, that they must explain something that is not familiar to ordinary people without becoming excessively pedantic. So, they are simply saying that they are NOT trying to say that there are 23 hours, 56 minutes, and 4 seconds in the normal day by which we regulate our times of sleep and wakefulness. That day is exactly 24 hours in length... except for a day in the spring that is 23 days long, and a day in the fall that is 25 hours long. Because we now do those things by the clock, not the sundial. It is not *astronomers* who have, shall we say, "corrupted" people into thinking of the artificial 24 hour mechanical clock day as the real day, so much so that except for noting whether it is light or dark, they are unaware for the most part of what the Sun is doing. This, rather, is simply due to the mechanized life we now live. So, to explain things to such people, they must begin in a simplified form. John Savard

It probably won't take me long to put you back in there. But I thought we might both enjoy trying to find common ground first. o note that the earth roration rate varies slightly o sidereal day = 360° o solar day = 361° approximately as the earth progresses about 1° in its orbit wrt the sun.

" I can understand that this might seem to be a gruesome spectacle! After all, we know the 24 hour day corresponds to 360 degrees. How can a different 23 hour 56 minute and 4 second day *also* correspond to 360 degrees? But, as a matter of fact, they do! How can that be? Because the correspondence is a *static* one. The Earth is a sphere, and longitude makes a 360 degree circle. So, at any one moment, the different places on the Earth cover all 360 degrees of angle with the Sun, once and only once, corresponding exactly to the 24 hours of a solar day. Also at that one moment, the different places on the Earth cover all 360 degrees of angle with the stars, once and only once, corresponding to the 24 short sidereal hours of a 23 hour, 56 minute, and 4 second sidereal day! But what happens 24 hours later? Then there is *motion*. And it is in motion that the difference in time between the solar day and the "sidereal day" axial rotation becomes apparent! 24 hours later - give or take the few seconds that might be that day's accumulation of the Equation of Time - it is the same solar time as it was 24 hours ago everywhere on Earth. Because the Earth advanced around the Sun by a degree, however, after 24 hours it is *not* the same sidereal time as it was 24 hours ago; by that clock, it is about one degree in angle, or four minutes of time, later. So the sidereal time repeated itself four minutes ago. John Savard

"When one moves eastward 15=B0 in longitude, sidereal time is larger by one hour (note that it wraps around at 24 hours). " http://en.wikipedia.org/wiki/Sidereal_time The usual tactic of making things personal never work with this material,no matter how hard you numbskulls try,the magnificent principles which create the 24 hour day and subsequently keep clocks in sync with the axial cycle at 24 hours/360 degrees are too enjoyable when the 'sidereal time' junk is removed .It all hinges on the observation that the natural noon cycle is unequal and then shades off into the human devised principle of the 24 hour day via the Equation of Time - http://www.xs4all.nl/~adcs/Huygens/06/kort-E.html It is heartening to see people who are not directly involved in studying the motions of the Earth try to draw attention to the planet by way of music concerts and this stands in sharp contrast to you freaks who pretend to know about the motions of the Earth but believe in a silly notion that noon cycles are equal.Organisatiuons such as the NMM promote the idea that a location rotates to noon in 24 hours - http://www.nmm.ac.uk/server/show/nav.00500300l005001000 The explanation is even more gruesome than the Wikipedia 'explanation - "Each solar day the Earth rotates 360=BA with respect to the Sun. Similarly the Earth rotates 360=BA with respect to the background stars in a sidereal day. During each solar day, the motion of the Earth around the Sun means the Earth rotates 361=BA with respect to the background stars." NMM It is brilliant that good people will try to increase awareness of the planet and I will do my part in showing how the motions of the Earth make existence possible and that people are astronomers insofar as we live by the great astronomical cycles.What you crowd do is try and draw attention to yourselves hence the 'leap second' junk and the 'sidereal time' reasoning from which it springs. So,the great astronomical insights wither in the hands of anti-heroes such as yourselves ,too unintelligent to know what damage you are doing and too dull to grasp just how magnificent the original timekeeping and structural astronomical insights actually and beautiful they are.

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/rocket_sci/orbmech/period.html How the worst type of reasoning ever applied to timekeeping and the Earth's motions will be for future generations to consider but right now a single individual is required to affirm the observation that the noon cycle is unequal. Your kind will stick with the destructive indoctrination that astrological 'sidereal time' breeds and the silly concepts which arise attaching axial rotation directly to constellation geometry - http://hypertextbook.com/facts/1999/JennyChen.shtml http://en.wikipedia.org/wiki/Image:Tiempo_sid%C3%A9reo.en.png I enjoyed the brief spell away from diseased minds that cannot grasp the simple way the 24 hour day is created,how the 24 hour cycles elapse into each other and how the principle of the average 24 hour day is applied to the axial cycle as a 24 hour/360 degree correlation. You all want the title of 'astronomer' but until this is set straight nobody dares use that once dignified title and I do not care how many doctorates it offends.

Again, Kelleher, let me simplify it for you with this diagram.

I do not know of any situation which is comparable to this one,the most basic of all astronomical observations known since antiquity that no two noon cycles are of equal duration hence the Equation of Time correction to create the 24 hour cycle and keep these cycles ticking over. If it was a matter of some obscure and minor fact I could understand the lack of responses but to knowingly support a concept which has a location rotate constantly to noon in 24 hours should shock people - http://en.wikipedia.org/wiki/Image:Tiempo_sid%C3%A9reo.en.png The irritation in dealing with people who take pleasure in making up stories to suit whatever conclusion they wish ,for such is the 'sidereal time' justification for the Earth's motions,pales in comparison to the sheer lack of appreciation of the correct principles,not just timekeeping but more importantly heliocentric reasoning. If somebody else can think of a dismal situation,apart from hunger and poverty,that is more immediate than this one I certainly can't think of one.The Earth's axial and orbital motions condition global climate and the seasons yet the people responsible for informing the political authorities who in turn will make crucial decisions cannot even express the daily cycle correctly.

This is not true. 360.9856 degrees - axial rotation of the Earth in 24 hours exactly (for a rotation that performs 360 degrees in 23 hours, 56 minutes and 4 seconds) minus 0.9856 degrees - angular advance of the Earth around the Sun in 24 hours, simply the *average* of this quantity over the course of a year, equals 360 degrees - one solar day going full circle in 24 hours, also the *average* of this quantity over the course of a year by the Equation of Time. Now, if instead of using the equation 360.9856 - 0.9856 = 360 we use it in this form 360 + 0.9856 = 360.9856 then, since the 360.9856 is the *exact* sidereal axial rotation of the Earth in 24 hours, it might seem to depend on the Earth 'rotating to noon' in exactly 24 hours. But, no, that is still faulty reasoning. Yes, if 360 and 0.9856 are only averages, this equation by itself does not prove that 360.9856 is anything more than an average for sidereal axial rotation in 24 hours over the course of a year. So we bring in Newton's Laws, that an undisturbed rotational motion will remain uniform, or we bring in actual transit circle observations to say, after we have, with the equation, explained what the 23 hour, 56 day, and 4 second period is *for*, that this period is also a uniform one by our mechanical clocks, not needing to be averaged over the course of a year the way the other ones are.

It *would* require that *if* the Earth's orbit around the Sun was a perfect circle, not tilted with respect to Earth's axis. Since that is not true, the relation of the Sun to the Earth only compensates *on average* for the difference between 23 hours, 56 minutes and 4 seconds - and 24 hours. Because the compensation is not always exact, but only averages out over the course of the year - you can have the Equation of Time! > Out of all the people who visit sci.astro.amateur,I have yet to see > one individual affirm that the daily noon cycle is > unequal. I guess you didn't look at my web page at http://www.quadibloc.com/science/eot.htm yet, then. The return of a star to the meridian is equal - 23 hours, 56 minutes, 4 seconds. The orbit of the Earth around the Sun takes one year. If that were perfectly uniform, it would convert 23 hours, 56 minutes, and 4 seconds to a perfectly uniform 24 hours. But because it is _not_ uniform, due both to the elliptical orbit of the Earth, and the tilt of the Earth's axis compared to the ecliptic, the uniform axial rotation of 23 hours, 56 minutes and 4 seconds is converted instead to an *unequal solar day* which only averages out to 24 hours in the course of a year! The time between "noon" from one day to the next, if you mean sundial noon and not clock noon, is indeed not exactly 24 hours; it differs slightly in a day, and these differences accumulate to up to a difference of 15 minutes from the mechanical clock at certain times of the year. This I do know, hold, and affirm to be true. John Savard

So,you are all concerned for the welfare of one of your members in sci.astro.amateur yet you numbskulls inflict the worst misery on the rest of humanity with your stupid notions.Good kids could easily understand that the natural noon cycle is unequal and how brilliant men equalised the natural cycle to a 24 hour cycle and kept these cycles elapsing into each other.Then move on to how Copernicus isolated orbital motion which left the axial rotation to explain the daily cycle and subsequently the principles which keep clocks in sync with axial rotation at 24 hours/360 degrees. Out of all the people who visit sci.astro.amateur,I have yet to see one individual affirm that the daily noon cycle is unequal.Considering how important it is to get an accurate picture of the Earth's axial and orbital motions with respect to each other and to the Sun,to see all these doctoirates and polished reputations not even appreciate the basic daily cycle is incredible. > No standard web pages containing all your search terms were found. > > Your search - "location rotates to noon in 24 hours exactly" - did not > match any documents. > ===== > > It seems that -you- are the only one who is saying it, > in fighting a straw man of your own making. > > Go play somewhere else, > > Jan It Iis always a matter of appreciating the basic principles which create the 24 hour day out of the unequal daily cycle so until you learn them from a great astronomer like Huygens,you can forget your 'leap second ' junk - http://www.xs4all.nl/~adcs/Huygens/06/kort-E.html You have to be entirely stupid to believe a noon cycle is unequal subsequently if you excuse me from being bothered with your unintelligent response - http://en.wikipedia.org/wiki/Image:Tiempo_sid%C3%A9reo.en.png

The orthodox astronomical community is well aware of the Equation of Time. While the 24 hour day is a human creation - born out of a desire to use a uniform time scale - it is also the actual average of the solar day over the course of a year. It is not an arbitrary human creation. And uniform time exists in nature; it is the time scale by which many natural processes are appropriately measured. > Because the Equation of Time principles are easy to grasp and > enjoyable,they should not have to compete with conceptual junk such as > the 'sidereal day',a counter-productive 'sidereal' concept that is sub- > geocentric in content and catastrophic for this era where the motions > of the Earth mesh with climatiology. . Since the 23 hour, 56 minute, and 4.1 second period is not a period of light followed by dark, yes, it really shouldn't be called a "day". It should be called the Earth's axial rotation period. That is a valid point. > I am sorry your dull mind brings astrological geometry into the > motions of the Earth or rather justifies the motions of the Earth by > way of the distant stars instead of our own star..It is the lowest > people intellectual level a parson can fall to and unfortunately this > entire group who calls themselves 'astronomers' suffers from that > stupidity. . Here, I'm afraid, though, I have to say that you are completely wrong. We don't bring in the distant stars instead of the Sun because we're astrologers at heart, or out of some perversity. The motions of the bodies in the solar system, like everything else, is best understood by starting from simplicity rather than complexity. The uniform axial rotation of the Earth is one simplicity. The orbit of the Earth around the Sun is not completely simple, since it is elliptical, and since it is not on the same inclination as the Earth's equator, but it cannot be reduced to further simplicity. We start with those two simple things to build up to the Sun's apparent motion in the sky, which results from the combination of these two things. It made sense, hundreds of years ago, to start with the daily movement of the Sun, and then note that in a given season, the axial tilt and elliptical orbit would affect the axial angle, relative to the stars, of the Earth found at a given sundial time of day. Because it was the Sun, and not mechanical clocks that were in people's experience then. But now it would only be confusing. If the Earth's axial rotation is regular, that regularity isn't caused by irregularities in the time on a sundial being *cancelled* by the Earth's orbit; rather, the Earth's rotation is regular because nothing is pushing on it to speed it up or slow it down, and the Earth's orbit causes the sundial to read differently from a mechanical clock. The uniform scale of time, even if the particular form of it we use, a 24 hour day divided into 86,400 seconds, is a human creation, is still a natural thing, and is the basis of natural processes that change over time. On Mars, the Equation of Time goes through its paces over the course of a Martian year, about twice as long as ours - and instead of a Martian sundial being wrong by up to 16 minutes, it can be wrong by up to 50 minutes. Sundial time is a local matter, resulting from the peculiarities of the particular planet you happen to live on. Uniform time, however, governs the motions of the planets, the processes of chemistry, mechanics, electricity, and any other physical process you care to name. First, we have to get *from* the 24 hour day that is what people normally think of as a day, to the Earth's 23 hour, 56 minute, and 4 second axial rotation that actually is uniform. We do that without bringing in the complications of the Equation of Time at that stage, because we have one simple fact to explain: that period, although not in normal human experience, is the regular one, and hence the fundamental one. Once we shift from sand to bedrock, then we can show how the motions of the Earth around the Sun combine with the turning of the Earth on its axis to yield the solar day that is governed by the Equation of Time and only averages to 24 hours. We explain it in that order because that is what is simple and straightforwards to understand - just as the operation of any machine is explained from the simple and uniform beginnings of its operation, not from its complicated end product.

That is true. In fact, it is actually *because* this is true that Gerard Kelleher is having problems accepting the simplified explanations of the Equation of Time that put the mechanical clock first - because that is what ordinary people today are used to. Instead, he prefers the way people like Kepler and Huyghens explained these things correctly - feeling that the way today's astronomers discuss the subject is not only not the same as the truth presented by Kepler and Huyghens, but is even worse than the geocentric version from Ptolemy - hence his term "sub-geocentric". Yes, the _Almagest_ did discuss the Equation of Time. It was presented as a correction that would be needed if one were calculating the position of the Moon. And that's certainly a legitimate way to bring in a uniform time scale; Ephemeris Time was constructed by deriving uniform time from the motions of all the planets. But it is not the simplest conceptual territory from which to present the Equation of Time. Nor does it defend Newton from the charge of simply making uniform time up as dramatically as pointing out that, in his day, there already were mechanical clocks of a sort. John Savard

I am setting up to wax poetic. First, the evil capitalists made people wake up in the morning by mechanical clocks and not the Sun so that they would work each day for the same number of rotations of the steam-engine driven shafts that powered the looms over which they slaved. But departing from the Sun by +/- 15 minutes by ignoring the Equation of Time to correct clumsy mechanical clocks was only the beginning! Then, to simplify railroad schedules, they once again violated the natural daily cycle by only allowing clocks to be set with one-hour differences from a clock set to mean solar time in Greenwich, rather than the mean solar time of one's own city. This invention, Standard Time, led to an additional departure of +/- 30 minutes from real mean solar time, or even more if time zone boundaries were shifted for convenience. And then they used the exigencies of war to get everyone up an hour earlier to conserve fuel - Daylight Savings Time, or Summer Time - thus completing, and making the most blatant, their abuse of the mechanical clock to enslave the common man!

You err on the left. On the right one may note that the one and only true time is the time of the sun, as indicated by the sundial. It is the time given to mankind by god, and any tampering with it is blasphemy. It was an invention of evil city-folk who want the honest hard-working farmer to get up an hour too early to milk the cows in the dark to get them their fresh milk in time. If god had intended that we should get up an hour later he would have commanded the sun to stand still for an hour, as he did for Joshua. Jan

Criticising science for its "lack of feeling" is as stupid as criticising art for being "unrealistic". Or to criticise a wrench because it's not good for hammering in a nail, or criticising a hammer because it's no good for screwing in a bolt. Different tools have different uses.

Mathematical logic has no feeling but astronomy is full of it insofar as we are all astronomers by virtue of living by and with the axial and orbital motions of the Earth.The wonderful expression of Pascal that mathematicians make themselves look ridiculous is borne out in this era where only those touched by insanity believe in relativity,time travel and the staple of rubbish fed to people for the last century under the guise of 'astronomy'. Astronomy was always a gift,not just a magnification exercise but as an adventure suited to those who have developed their intutive intelligence and can feel what it means to be an astronomer - "These principles are so fine and so numerous that a very delicate and very clear sense is needed to perceive them, and to judge rightly and justly when they are perceived, without for the most part being able to demonstrate them in order as in mathematics, because the principles are not known to us in the same way, and because it would be an endless matter to undertake it. We must see the matter at once, at one glance, and not by a process of reasoning, at least to a certain degree. And thus it is rare that mathematicians are intuitive and that men of intuition are mathematicians, because mathematicians wish to treat matters of intuition mathematically and make themselves ridiculous, wishing to begin with definitions and then with axioms, which is not the way to proceed in this kind of reasoning. Not that the mind does not do so, but it does it tacitly, naturally, and without technical rules; for the expression of it is beyond all men, and only a few can feel it."

You are correct that the physical noon cycle is not 24 hours exactly. There is no rotation in nature in our Solar System that has an exact uniform period of 24 hours. Astronomers know this. They know that 24 hours is only the average, over the course of a year, of the natural noon cycle. Occasionally, some references will start with the simplification of assuming a perfectly circular and uniform orbit for the Earth, as an approximation, to explain the relation between Earth's synodic day of 24 hours and the sidereal day of 23 hours, 56 minutes, and 4 seconds. Sometimes they will even fail to point out that this is a simplification, thus over-simplifying. But that does not mean that a star does not return to the meridian in 23 hours, 56 minutes, and 4 seconds. And since the Solar System is heliocentric, with the Earth going around the Sun once a year, to keep pace with the "dial" on the 24 hour clock - with the average apparent position of the Sun from Earth making a full circle around the Earth in a year - the "hand" of the clock, to keep days coming at an average of one every 24 hours has to run a little faster. So the Earth's uniform axial rotation gives it a rotation period of 23 hours, 56 minutes, and 4 seconds. Starting from this, one can then appreciate the causes of the Equation of Time. One cause is that the Earth's orbit is an ellipse, with the result that Kepler's Third Law makes its speed in moving along that ellipse unequal. (Earth's orbit is so near a circle in shape, though, that the Ptolemaic "deferent" at the other focus of the ellipse is a very good approximation.) Another cause is the fact that the rotational axis of the Earth is not exactly perpendicular to the plane of the Earth's orbit around the Sun. (If it were, that would be a concidence - just like a calendar year of exactly 365 days!) At the equinoxes and the solstices, this has no effect, but between them, the direction of the Sun from the Earth is not exactly what one would expect in order to compensate for the uniform axial rotation of 23 hours, 56 minutes and 4 seconds and yield the 24 hour day. So the Sun does not coincide with the mechanical clock for that cause as well. The combination of these two factors yields the Equation of Time. We start from that which *is* uniform, the axial rotation of the Earth when compared to the stars, and that which is regular in its period, although not perfectly uniform, the revolution of the Earth around the Sun, and proceed from these simple bases to the complexity of the actual daily cycle of the Sun in the sky. Perhaps you may feel this approach is "backwards", but it is the one that makes the mathematics more simple to follow, and it is mathematics that one needs to calculate accurate ephemerides. And this does not make astrologers of astronomers. John Savard

Nobody appears to have the intelligence to enjoy how the average 24 hour day was transfered to a 'constant ' axial cycle without tying the clock directly as a physical manifestation of axial rotation.The equalising noon correction (Equation of Time) which formely kept one 24 hour day elapsing into the next 24 hour day simply keeps the axial cycle constant as expressed a by 4 minute equals 1 degree of terrestrial longitude and geographical seperation. I will wait for people who have the neccessary intelligence to appreciate what is so wonderful about the true astronomical principles and what is so damaging about a concept which believes that the physical noon cycle is 24 hours exactly .

Yes, the natural cycle is not 24 hours exactly; people who use sundials are familiar with this. Some explanations of the Earth's motions may leave out the details, but the Equation of Time is quite familiar to contemporary astronomers. Over the course of a year, as you point out, the length of a day can be averaged out. The length of the year is a constant; this is a natural cycle that always has the same length. This cycle, of course, is not an exact multiple of the 24 hour day, again, as you have noted. But while the cycle of the Sun in our sky is a cycle that only averages to 24 hours, if you add one to the (uneven) number of 24 hour days in the year, to get a shorter cycle, representing the Earth's own motion independently of its orbit, then it is found that, by a mechanical clock, the transit of a star overhead at a given location recurs at a regular interval. This same interval applies at all times of the year. This is a fact, and it has nothing to do with astrology. Astrology imbues the positions of the planets against the constellations with meaning having to do with people's fortunes or their personalities. But the stars are real objects, and so noting their positions is not astrological in nature. The sidereal day is not some kind of mistake. It is a basic, regular, natural cycle. From this natural cycle, and the fixed cycle of the year, but given the Earth's elliptical orbit, the solar day that only averages to 24 hours over the course of the year comes into being. We look at the course of the Earth in the heavens, and divide it into its parts, each of which is a regular motion, to understand the whole. Whatever your reasons may be for objecting to this, it works, and it is understandable. John Savard

Yes, clocks don't grasp a "time dimension". They simply are devices that, because they do as far as possible, the same thing over and over, keep a standard pace. As for the Equation of Time, how is it obtained? Is it simply found by comparing a clock with a sundial for a year, and keeping a table of the differences? Or, after that _has_ been done, to obtain what the result of the equation of time should be, are there things in the heavens that behave simply, like our clocks, whose combined motion leads to a way to derive the Equation of Time as a mathematical formula, from our theory of the motions of the Earth in the heavens? While I believe the latter is the case, the way I would derive the Equation of Time makes use of what you refer to as the errors of Newton and Flamsteed. If there is a theoretical derivation of the Equation of Time based on valid heliocentric reasoning, what is it? John Savard

Nah, they could both agree on just using the UT time scale. It always has 60 seconds per minute, and it doesn't drift away from the rotation of the Earth since it's defined by the rotation of the Earth.

Well, you see, they brought in this system of timekeeping with leap seconds some years ago. And so there have been several leap seconds since they did. So there's a big difference, several seconds, between today's UTC and UTC if we never had any leap seconds since we started it. If a new time standard was brought in, it would match with the time standard - UTC - that people use for their clocks. At the time the 32.184 second difference existed, that wasn't between the new time standard and old civil time. Those matched. That was between the new time standard and *Ephemeris Time*. This was based on just using the SI second, rather than a longer second matching the Earth's slower rotation. It was used because a uniform time scale was desired for working out the motions of the planets; so this time scale, just like today's atomic time, if no leap seconds were used, kept falling further and further behind. So no one had to set their clocks back by 30 seconds - and everyone *would* have, if they used Ephemeris Time rather than the ordinary time of day for the new standard. At the point the new standard was brought in, the difference between Ephemeris Time and ordinary civil time was 32.184 seconds, and that's what caused the jump.

They just wanted a tribal marker of their own, Jan
