Description Acceptable. Archimedes used Aristarchus of Samos’s work on this idea for an upper-bound calculation in The Sand Reckoner. Prior to being burned at the stake, Giordano Bruno’s belief in this idea (-5[1])led him to promote (10[1])pluralism. Ibn al-Shatir may have influenced a proponent of this idea when he eliminated his use of the equants proposed by the Almagest. A stand-in for Pope Urban VIII argues with a proponent (10[1])of this idea in (10[1])The Dialogue Concerning the Two Chief World Systems. (10[1])Tycho Brahe’s alternative (10[1])to the Ptolemaic system informed Kepler’s model of this theory. For 10 points, identify this model advanced by Copernicus which replaced geocentrism. ■END■ (10[1])
