Scientific research explanation greater thought logic and calculations are truly in my mind, some of the best things to hear.

And yes, they are different. The reason we KNOW the earth is round is because SO MANY different natural forces on earth prove

    • For those of you wondering, it was known that in Syene, there would be no shadow at high noon during the summer solstice every year. So Eratosthenes only needed to be in Alexandria on the same day and wait for high noon (when the shadow is shortest) to see if there is a shadow or not.
