The History and Practice of Ancient Astronomy Book

In Ptolemy's The Almagest, the earth is placed at the centre of the universe and the planets move in crystal spheres against a backdrop of the fixed stars. While these ideas have been swept away since the Scientific Revolution, Ptolemy's influence on astronomy was profound and long--we'll be dealing with the Y3K problem before Copernicus' time of influence catches up. James Evans, historian and astronomer at the University of Puget Sound, believes that "staying close to the practice of astronomy means explaining a subject in enough detail for the reader to understand what the ancient astronomers actually did. As this unique book teaches you to do astronomy the old-fashioned way, you gain a deeper understanding of what the Greeks and their successors thought and did. "There is all the difference in the world between knowing about and knowing how to do," says Evans. The History and Practice of Ancient Astronomy is truly hands-on history and deserves to be widely imitated. --Mary Ellen Curtin, Amazon.comRead More
