Ibn Hazm, was who i was referring to, who had helped calculate the Earth's circumfrance to within 200km of the truth. It appears disputed as to where this happened first and frankly, i dont really care.
Regardless, I was merely responding to your needless and objectionable reply to my post. It should have been painfully obvious that I wasn't being calculated or specific, and even taking the time to disprove my playful discussion is wildly off-topic.
Having looked up some of your other posts though, it appears clear that you thrive on argument for the sake of argument, and even managed to turn an entire thread against yourself elsewhere on the board.
So have fun with that.
