Trolls deliberately post garbage, Kellerher actually means what he says. Kellerher isn't a troll, he's merely deranged. The distinction is blurred nowadays. Its still best not to respond however. It only encourages him. While you were left with nothing to do but complain about me ( I really do not care) ,I was working on how to distinguish the expansion of hotter temperature bands towards the poles as distinct from the natural oscillation - http://groups.google.ie/group/sci.en...6d67b3412dfad1 Of course you manage to believe an idea that no sane person will, touch - http://upload.wikimedia.org/wikipedi...3%A9reo.en.png It takes two poles and a stopwatch to expose that the framework admired and used by empiricists is based on the notion that you can justify the axial and orbital motions of the Earth using the calendar system.Maybe when there is agreement among genuine people that Flamsteed made an error that is so awful that it takes a diseased mind to carry on with the 'established fact". I have stayed away from using the term 'illness' top people who cannot reason properly,for my part,it is unfamiliarity which excuses most here however that time has long since past.If you are too simpleminded to grasp what went wrong and why it is dangerous for civilisation then you do not belong anywhere near astronomy,climatology and any other related discipline. |

Just what IS a double star? The dictionary definition is "Pair of stars that appear close together". This includes true binaries, as well as optical pairs. Sirius A and B that orbit a common barycentre? Can't be that, too difficult to resolve. AFAIK, these are a binary system. Any old pair will do if they are both in the field of view of the telescope? I think the usual rule is that if you can see them with the naked eye, they're not an optical pair. They may well be a binary of course (/are/ there any binary systems that can be resolved with the naked eye? ) And no, this is NOT taken from wikipedia... |

I should have added that this is commonly called an asterism, or, if large enough, a constellation. Then all stars are doubles. No matter which star you look at there is another within 30 arc seconds of it. Indeed. I guess the point is, how many appear single stars visually but resolve into a pair at moderate resolution? From the Moon, yes. They must a be double city. Indeed. From the moon, London, Croydon and Slough would appear one city too. Thats kinda the point. Ok, and so is Bumf**k, Alabama. Childish. |

Into the bitbucket with you, my bucko.. : And no, this is NOT taken from wikipedia... I don't care where you got it, I'm not about to call Mars and Jupiter a double planet just because I've seen them "close together", On the other hand, if mars and jupiter remained visually close together for 100 years, what would you say? Assume you have no means of measuring their distance away (ie put yourself in the shoes of the astronomers who first catalogued doubles). so I'm asking what this strange fascination with "double" stars is and will continue to put "double" in quotation marks until supplied with a satisfactory answer. Allow me to put another word on quotes - "dork". |

I am enjoying this,binary empiricists arguing over depth perception.
That was alway the problem with astreologers with telescopes where all observations are pasted on a rotating celestial sphere and especially the subhuman justification using the return of a star in 23 hours 56 minutes 04 seconds. Androcles,you have the same problem with depth perception as all non astronomers have ,the fact that you can see the orbital motions of our planet and that of the others around the central Sun is enough to consign Isaac's silly view to the junkpile where it belongs - http://antwrp.gsfc.nasa.gov/apod/ap011220.html " For to the earth planetary motions appear sometimes direct, sometimes stationary, nay, and sometimes retrograde. But from the sun they are always seen direct," Newton Maybe you should instruct Mark here about the ultimate version of the Flamsteed/Newton astrological notions - relativity.Of course you both share the same error Flamsteed created before Newton arrived on the scene and subsequently are both locked in a struggle and a cult that is awful to behold.

Astronomy belongs to those who have depth perception ,understand the main Copernican reasoning in that time lapse footage of Jupiter and Saturn and know what is wrong with Newton's idiosyncratic approach. |

Ah... astrology spam. Pictures in the fire, pictures in the clouds, pictures in the stars. I was under the mistaken impression that these were sci. newsgroups but maybe Kelleher is talking to the right people after all. : Then all stars are doubles. No matter which star you look at : there is another within 30 arc seconds of it. : : Indeed. I guess the point is, how many appear single stars visually but : resolve into a pair at moderate resolution? Visually meaning less than 6th magnitude? : : From the Moon, yes. They must a be double city. : : Indeed. From the moon, London, Croydon and Slough would appear one city : too. Thats kinda the point. Bad example. Croydon is inside the M25, Slough outside on the M4. http://apod.nasa.gov/apod/image/0304/london_iss_c1.jpg Crawley would be seen before Slough and so would Dagenham, even tiny Sheerness, they emit more light. Can't tell with Dartford, it is under cloud cover in the image. : : Ok, and so is Bumf**k, Alabama. : : Childish. That's the point. Double stars (and lists of) are a childish concept, nothing more than astrology spam of no import or significance whatsoever. Meaningless drivel to be given as much weight as Kelleher's nonsense or any other crackpot's silly ideas. |
