The Great Ptolemaic Smackdown


Art by Sumashi


One of The Brickmuppet's Crack Team of Science Babes takes a break from the heat to point us to a piece by Michael Flynn, who gives an interesting analysis of the scientific process by which geocentricism was discarded. It bears reading in full because one important fact, often overlooked is that we only have 20/20 hindsight going backwards. Things which seem blindingly obvious in retrospect were not nearly so at the time. 

UPDATE: an excerpt:
Before you laugh at your ancestors, TOF invites you to prove that the earth is, contrary to your senses, in wild and careening double motion: spinning like a top and whipping around the sun without (somehow) leaving the Moon and Air behind, and without everyone stumbling around like dunkards.  You are not allowed to appeal to authority or to the success of NASA, or suchlike things.  You've got eyeballs and armillaries, and that's pretty much it.  Go. TOF will wait here
