The Pictorial Ptolemy and Copernicus by John A. Cramer (English) Paperback Book
17,73 €
The Pictorial Ptolemy and Copernicus. This is a great explanation of the Ptolemaic and Copernican systems in 36 diagrams, no equations! The often to-scale diagrams and the text explain the systems to a depth most readers would not attain by a reading and re-reading of the great works of Ptolemy and Copernicus.
