Résumé : |
Eratosthenes came close to a precise estimate of the circumference of the earth around the year 240 BC. His accomplishment depended on a verifiable tenet among his contemporaries: the earth was a sphere. At Syrene, the sun cast no shadow at the summer solstice. On that day, Eratosthenes measured the angle of the sun's shadow in Alexandria over 700 kilometers to north, at 7°12? or 1/50th of the circumference of a perfect sphere. |
