Most here are descendents of the dull and dreary celestial sphere
geometers who made Harrison's life so miserable,talentless men attached to the Ra/Dec system and the idiosyncratic way to justify the return of a star to a terrestial meridian using the axial and orbital motions of the Earth. http://books.google.com/books?vid=OC...ison+longitude No doubt your dominance is even more assured today than it was when Harrison wrote that but then again the document is a lovely reminder that the monarchy,the seafaring tradition and the inventiveness of the society at the time was still capable of blossoming in a hostile enviroment. At the core of relativity is Newtonian conceoptions,at the core of that is celestioal sphere geometry and at the core of that is a simple error made by Flamsteed in attempting to justify the celestial sphere sidereal value by using the Earth's axial rotation an subsequently orbital motion. "Flamsteed used the star Sirius as a timekeeper correcting the sidereal time obtained from successive transits of the star into solar time, the difference of course being due to the rotation of the Earth round the Sun. Flamsteed wrote in a letter in 1677:- .... our clocks kept so good a correspondence with the Heavens that I doubt it not but they would prove the revolutions of the Earth to be isochronical... " Nobody with the authority to recognise the fundamental error is one thing but that is provides an obstacle to understanding and using axial and orbital motions in isolation from each other proves to be the most remarkable situation of all.This is not just a matter of tidying up the fascinating Longitude story,the expansive and encompassing astronomical tradition is weighing heavily in on the matter and specifically the Western heliocentric astronomy of Copernicus and Kepler. Many will clam up out of indoctrination and incompetence but there are people capable of recovering the correct astronomical principles from the awful maneuvering of celestial sphere geometers . |
