"Blurb & Contents" "I can think of few better ways of introducing students to the history of astronomy than by using The Eye of Heaven as a text.This is science at its best.Not only does Gingerich make you think, he also forces you back in time and makes you think as astronomers did then. Students need this inspiration." David Hughes, New Scientist Astronomer and historian Owen Gingerich provides a fascinating introduction to three giants of early astronomy: Ptolemy, Copernicus, and Kepler. In these collected essays, Gingerich examines the revolution in man's conception of the universe brought about by the shift from the earth-centered cosmos of Ptolemy to the sun-centered model of Copernicus.
