: Sorry to confuse you with SamD, but you did seem to be agreeing with him. What do you suggest? Saying that Ptolemy's model was not good enough for 16C data? [[User:RSchlafly|RSchlafly]] 17:03, 3 November 2008 (EST)

:My outline for the article:
:#Start before Ptolemy. The geocentric system predated him in the ideas of Plato and Aristotle as a mainly philosophical construct (single center of motion, etc.)
:#Giving Ptolemy his right credit: He was the genius who made the system work. Great mathematics, best model for centuries to come...
:#Time-line of the problems: Tycho Brahe's meticulous observations - in the 16th century - lead to Kepler's new model
:#The post-bear-eye era: Galileos observations of the Jupiter moons posed a problem for the ''philosophy'' of ''Plato'' and ''Aristotle'', the observation of the [http://www.youtube.com/watch?v=OlnlbZHP-jk phases of Venus] a problem for the ''Ptolemaic'' system.

I'm a little confused about what this discussion is about. Modern astronomy clearly takes an earth-centered view when describing familiar phenomena such as [[sunrise]] and [[sunset]] (which we know are caused by the earth's rotation - not by a sun god ascending and descending the sky in a fiery chariot; and the "motion" of the sun against the background of the "fixed stars" is explained by the earth's annual revolution around the (relatively) immobile sun.
