Project Physics Text 2, Motion in the Heavens.
Harvard Univ., Cambridge, MA. Harvard Project Physics.
Astronomical fundamentals are presented in this unit of the Project Physics text for use by senior high students. The geocentric system of Ptolemy is discussed in connection with Greek concepts including Aristarchus' heliocentric hypothesis. Analyses are made of Copernicus' reexamination, leading to Tycho's observations and compromise system. A new universe is introduced by using Kepler's laws and Galileo's work. Terrestrial and celestial dynamics are synthesized by reviewing Newton's concepts about motions under central forces, inverse-square law, and earthly motions; and application of Newton's theories to heavenly events are discussed. The text unit is concluded by an explanation of the making of theories. Historical developments are stressed to help students understand the way in which science influences man's activities. Also included in the unit are a chart of renowned people's life spans in the emerging Renaissance culture and tables of planets and their satellites. Problems with their answers are provided in two categories: study guide and end of section questions. Besides illustrations for explanation purposes, a glossary of general terms is given in the appendix. The work of Harvard Project Physics has been financially supported by: the Carnegie Corporation of New York, the Ford Foundation, the National Science Foundation, the Alfred P. Sloan Foundation, the United States Office of Education, and Harvard University. (CC)
