Maybe some pedantic history buff (not that there are any on this message board. ) will correct me, but as I recall, people have known since Ancient Greece that the Earth was round. Erastothenes tried to use this knowledge to figure out the circumference of the Earth. He managed to come really close to the correct number for a guy who was working with little more than pencil, paper, and a compass.
