Leap seconds
Our ancestors created a system where they applied 86 400 leap seconds
after every 1460 days elapsed thereby aligning the constellational cycles with the annual cycles and allowing people to conveniently locate yearly progressions. Where are all the myopic people who will spend the next 1460 days talking about adding or subtracting a leap second because of some wayward idea that axial rotation can be derived from constellational motion. Maybe the next 4 years will bring big changes,just in time to celebrate the last chance to see the faster Venus overtake the slower Earth with the central Sun as a backdrop,the most immediate experience of Copernican reasoning for heliocentricity. |

Once you tie axial rotation to constellational geometry,you are forever trapped in it - http://www.opencourse.info/astronomy...phere_anim.gif Axial rotation has never been isolated and the closest my astronomical timekeeping ancestors came was to adapt the average 24 hour day to the axial cycle as a convenience but not as an observation.When Flamsteed decided to attach axial rotation to the equidistant celestial sphere geometry they were obligated to explain orbital motion. Call me what you will,my view exists with those who created the timekeeping system that everyone on the planet uses today as the 24 hour clock system and its calendrical extension while you follow a horrible system created around 1672.With a new orbital motion on view,it is time to stop refeencing the motions of the Earth off constellational geometry andmotion,the 'fixed stars' in other words.

Constellational motion ? *You're really a geocentrist aren't you! Once you tie axial rotation to constellational geometry,you are forever trapped in it - http://www.opencourse.info/astronomy...tion_stars_sun... Axial rotation has never been isolated and the closest my astronomical timekeeping ancestors came was to adapt the average 24 hour day to the axial cycle as a 'constant' ,by virtue of a convenience but not as an observation. When Flamsteed decided to attach axial rotation to the equidistant celestial sphere geometry they were obligated to explain orbital motion.and created an appalling atrocity by building on 23 hours 56 minutes 04 seconds,using a 3 minute 56 second/.986 deg difference to 24 hours and unbelievably created equable natural 24 hour noon cycles !!!! - http://upload.wikimedia.org/wikipedi...3%A9reo.en.png Yesterday a star returned 3 minutes 56 seconds ealier to the same location and today,Mar 1st,the same star will return 3 minutes 56 seconds earlier.There is a very good reason my timekeeping ancestors refered the daily cycle to natural noon and not to constellational geometry but that reason appears to be lost to genuine people as the current 'leap second' fad focuses solely on celestial sphere geometry. Maybe the next 4 years will bring big changes,just in time to celebrate the last chance to see the faster Venus overtake the slower Earth with the central Sun as a backdrop,the most immediate experience of Copernican reasoning for heliocentricity. Transits of Venus during Copernicus' lifetime were in 1518 and 1526, but no record exists of anyone having witnessed them. Teleescopes did not exist when the great timekeeping and structural astronomical achievements were created,the Copernican insights and the refinements by Kepler were accomplished without watches or telescopes.The main argument for the orbital motion between Venus and Mars ,in the Copernican era,was the observed behavior of the outer planets and specifically the resolution for apparent retrogrades.The faster Earth overtakes the outer planets hence the resolution for the observed behavior in terms of variations in luminosity and the apparent backward drift of the outer planets.Here is the Earth overtaking Jupiter and Saturn,the former still images show luminosity while the latter show the resolution of retrogrades - Luminosity variations - http://antwrp.gsfc.nasa.gov/apod/ima...loop_tezel.jpg Retrograde resolution - http://antwrp.gsfc.nasa.gov/apod/ima...2000_tezel.gif Why would anybody in their right mind go along with Newton's approach to and resolution for retrogrades which is at complete variance with how heliocentric astronomers resolve the matter based on orbital comparisons - "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 The slow and elegant resolution for heliocentric motion can be balanced by the superb and most immediate experience of heliocentric reasoning,the transits of the inner planets.The event in 2012 represents the faster Venus overtaking the Earth it is outer orbital distance from the central Sun.I watched the last time a transit occured and all this forum managed was - 'Venus crosses the face of the Sun' and nothing more.The excellent Youtube treatment is more like the lively way to approach this great event - http://www.youtube.com/watch?v=thBSDf4Ers4 Structural and timekeeping matters are intricate and complex enough and the greatest struggle is more often to simplify matters for those who have yet to develop that intutive intelligence to know what is going on.I am very much a person of my era and grealy admire the new tools availible to make astronomical reasoning and specifically the motions of the Earth more relevent to this generation.It is unfortunate that most here never feel the inclination to move beyond the observational convenience of the Ra/Dec system or worse,extend this system to heliocentric reasoning. Maybe you shopuld take Martin's 10 minute challenge where the galaxies hang like ornaments off the equidistant stars and constellations but if astronomy has come down to this,only the most indifferent know that something went radically wrong.At least now you know. |
