Document Summary
We generally trace the origin of greek science to the philosopher thales: was the first person known to have addressed the question, what is the universe made out of? > without resorting to supernatural explanations, his own guess, that the universe fundamentally consisted of water and that earth was a flat disk on an infinite ocean, was not widely accepted even in his own time, but his mere asking of the question helped set the stage for all later science. Anaximander: student of thales, in an attempt to explain why the sky appears to turn around the pole star each day, he suggested that the heavens must form a complete sphere, the celestial sphere, around earth, based on how the sky varies with latitude, he realized that earth"s surface must be curved, though he incorrectly guessed earth to be a cylinder rather than a sphere.
