英语词汇ptolemaic system的起源、历史背景-英语词源词典

Ptolemaic system. Before Copernicus scientists believed that the earth was the stationary center of the universe, a philoso- phy espousing the snug, smug little world where the sun, plan- ets, and stars moved benignly around us. This theory, the Ptolemaic system, was essentially that of Ptolemy, an Alexan- drine astronomer who lived from about a.d. 100 to 170. Clau- dius Ptolemaeus took his name from the Ptolemaic dynasty of Egypt, which reigned from the late fourth to the first century b.c. His famous work the Almagest, 13 books compiling his own and other astronomical findings, set forth the Ptolemaic theory. Nothing reliable is known about the great astronomer, geographer, and mathematician aside from his work, which in- cluded his famous Geography. His Ptolemaic system remained virtually unchanged and unchallenged until the heliocentric system advocated by Copernicus and Kepler replaced it in the 16th century. See copernican.
