Samos Bags
Main Tag:
Description: Rendered on a deep dark background, this artwork presents the half-moon method: Earth, Moon and Sun forming a right triangle at the Moon, with the angle θ at Earth and the relation EM / ES = cos θ. Around 270 BC, Aristarchus of Samos proposed that the Earth revolves around the Sun, eighteen centuries before Copernicus. He also used the half-moon geometry to compare the distances of the Moon and the Sun. Made for astronomers, stargazers and anyone who looks up at the night sky with wonder, it suits a study, bedroom or observatory corner.
