I wrote that the pole star was in Draco not Polaris in Draco.

Exactly the point, it was ambiguous.
" 5000 years ago the pole star was in Draco."


Well, it was perfectly clear to me... just sayin'.


Well, it was possible for me to determine Collins' intent, but I seriously
doubt Kelleher could have done so... just sayin'.

Well, you'd be right in just sayin' that...

All here would be grateful if you could learn the art of just one (short) sentence...

You are already dead to astronomy and terrestrial sciences if you imagine there are more rotations than days in a year...


All it takes are 2 sticks and a stopwatch and you could prove this to your own satisfaction...

All it takes is to count the number of times the Sun rises and sets or how many times the stars come out between Jan 1st and Dec 31st to determine the number of rotations in an orbital circuit but to truly ascertain the value requires the referencing system for the extra rotation which closes out 4 annual circuits. The parent 1461 rotations observations is re-directed in separate formats ,firstly to the 365 1/4 rotations per orbital circuit and secondly to human timekeeping and the 24 hour system within the 365/366 day calendar framework.

The original heliocentric astronomers used a different system to the older referencing system where Sirius defines the Earth's position in space using the number of times the Earth turns by counting how many noon cycles there are rather than how many times the stars come out across an orbital period even though one observation is as valid as the other.

The horror of it all is that you take the same simplistic route as the guy who thinks he sees a skull in a coal vein and draws his conclusion whereas your crowd does roughly the same thing with a watch and stellar circumpolar motion. It doesn't matter if it is a generational thing where the education system creates a conduit for repeating the error across the centuries, to not notice that the steady progression of 24 hour days keep in sync with the steady progression of rotations across an annual circuit is a sign of a lack of spirit - a kind of living death in other words.

The great astronomers used a system where the Sun moves through the Zodiac rather than the more productive line-of-sight perspective where the stars move behind the central Sun in sequence as the Earth moves through space -

"The second is the yearly motion of the center, which traces the ecliptic around the sun. Its direction is likewise from west to east, that is, in the order of the zodiacal signs. It travels between Venus and Mars, as I mentioned , together with its associates. Because of it, the sun seems to move through the zodiac in a similar motion. Thus, for example, when the earth's center is passing through the Goat, the sun appears to be traversing the Crab; with the earth in the Water Bearer, the sun seems to be in the Lion, and so on, as I remarked." Copernicus

Precession is accounted for using the older system which used the first appearance of a background star to define the Earth's orbital position in space and the leap day rotation to center the Earth back to its orbital position to a close approximation. The additional leap correction provides a further detailed centering allowing for the over compensation of the leap day rotation hence the great astrological ages including the Age of Aquarius are no more as we grow up in the space age.

I would say it should make you all happy to see the demise of the poetic astrological 'Ages' but you are not really a cruel and crude people who get your only satisfaction from destroying the delicate and intricate nature of astronomical reasoning, you come across as empty vessels who can't even manage to associate the Sun rising and setting as the Earth turns once each day.

There was no ambiguity except to someone who thinks grammar is more
important than science, You have already admitted that you lied, You
understood perfectly but wanted to obscure the discussion.
I'm pretty sure Oriel understood as well. He just ignores inconvenient
facts in favour of his own superstitions. Ypu come across like a pathetic
1950s teacher whose only pleasure in life is attempting to show how much
better he is thaqn his pupils (who all laugh at him behind his back).

How sure is pretty? Palsing doesn't agree with you, he's beautifully sure
and he's made as many, if not more, SERIOUS attempts at teaching Kelleher
than your or Quadiblockhead put together.
You just ignore the inconvenient fact that the sun warms the Earth in favour
of your own CO2 superstition that you hallucinate is science.
You come across like a 1940s sadistic paedophile teacher whose only pleasure
in life is caning his pupil's backsides for not learning their seven times
tables by rote (who all live in dread of him behind his back and quake in
front of him too). What you wrote was ambiguous and instead of simply
accepting that fact and letting it lie, learning from your error, you are
now trying to cover your arse and blame me for pointing it out.

The narrative of sea ice evolution is also the narrative of the polar day/night cycle, something that is impossible to miss or explain with a surface rotation -

http://upload.wikimedia.org/wikipedi...precession.svg

The idea of axial precession as the original heliocentric astronomers was also the reason they didn't differentiate between inner and outer planetary retrogrades so there are several intertwined issues going on simultaneously when dealing with the proper perspective which begins with an observational certainty -

http://upload.wikimedia.org/wikipedi..._on_Uranus.jpg

It is not possible to make people appreciate something as lovely as another surface rotation which is behind the polar day/night cycle,at least those people who have no sense of the technical details nor the historical reasons why it has been missed up to now.

The new approach to the seasons in the 21st century is the equivalent of 1+1=2 yet the dull and the sullen would have the world they have a handle while promoting the old 'tilt towards and away from the Sun' as a means to explain what only the orbital surface rotation can.

Welcome to 21st century astronomy for all those who have the sense of adventure to engage with imaging.

Dear,oh dear - my poor proofreading once again regardless as to whether it is read or not.

It should have read - it is impossible to explain sea ice evolution and the polar day/night cycle without the surface rotation as a function of the Earth's motion through space. Although all locations in turn face the Sun through the annual circuit, the polar latitude is of particular interest as it looks like this ,a view currently obscured by the notion of axial precession -

http://upload.wikimedia.org/wikipedi...precession.svg

I would always imagine that true observers would be delighted with the perception that they turn to face the Sun in two separate ways as summer/winter is really an offshoot of the polar day/night cycle when combined with daily rotation.

Stargazers are fine in the ability to identify objects or watch them in close proximity to each other but the limitations of this within a celestial sphere context prevents others from opening the door to an astronomical treasure with one topic just as delightful as the next.

I might, just might, have had what some call a "light-bulb moment".

Our pet parrot said, "I would always imagine that true observers would be delighted with the perception that they turn to face the Sun in two separate ways as summer/winter is really an offshoot of the polar day/night cycle when combined with daily rotation."

Yes Gerald, I agree with you. The night sky at midnight GMT in January isn't the same as the night sky at midnight GMT in July and the height of the sun above the local horizon at noon GMT isn't the same in December and July either. The trouble is that for years you have consistently refused to accept this. Have you finally changed your mind??

Considering the polar day/night cycle in a more human way may help those who experience the blues as the night/winter sets in and lifts as Spring shows itself. The contemporary lifestyle and the lack of astronomers able to weigh in on the issue probably makes life unnecessarily miserable for many people and especially as they get older.

Just as the human body needs daily rest to gear up for the day ahead as the planet turns once, so also do we retain the slowing down with the rest of nature through the winter months as the planet turns as a function of the Earth's motion through space. These dual day/night cycles represented by individual motions help us adjust so long as we know that the slowing responses are normal for the human body rather than disorders, almost a signature of hibernation as it were.

Thew full-on lifestyle of the 21st century doesn't take into account the needs of the human body and indeed a younger and more energetic person can overcome the orbital day/night cycle and the necessity to adjust to changes in darkness and temperature but there are people out there who really need to know that their bodies are informing the mind to slow down or adjust to a different routine in accordance with the onset of orbital night.

Uranus will have a circle of illumination just as the Earth does however its unique orientation and the rings make it easy to envision the appropriate orbital surface rotation to the Sun and applied to the Earth as a matter of course.

People sometimes say that spirits are low during dull or dark times but at least when people know that their experiences are temporary and normal then they can act instead of masking the difficulties with pills or drink.
