Pre-Ptolemaic Anticipations
摘要
Four worthies are usually cited, within astronomical histories, as subsequent to Aristotle and prior to Ptolemy. These are Heraclides (fourth century B.C.) and Aristarchus (fl. 281, B.C.), Apollonius and Hipparchus (third and second century B.C.). How do they further our study of the explanation-prediction contrast as it stalks through the history of planetary theory?
