Answer 1

$\large{\frak{\red{Answer}}}$

${\green{\mapsto}}$ Probably the discovery that the Earth is round. By Eretosthenes in the third century B.C.E. He even determined the circumference of the Earth to a remarkable level of precision for the time. Coming within two percent of actual distance.

Another remarkable achievement was be the building of the Antikythera machine. Built between 100 B.C.E. - 200 B.C.E. An ancient hand powered multi-geared analogue computer used to predict astronomical positions of the Sun and Moon and the major visible planets in various constellations, and during the various seasons.

Nothing like it was built again until relatively modern times.
