Books By Ptolemy, Professor Christián C. Carman - Author

Claudius Ptolemy (about 100–170 CE) lived in Alexandria, Egypt, part of the Roman Empire. A mathematician, geographer and astrologer, his famous book on astronomy codified the ancient view of the universe, with the sun and observable planets orbiting around the earth. This geocentric perspective was succeeded 1400 years later by the work of Copernicus who determined that the earth and other planets of the solar system revolve around the sun. Christián C. Carman (introduction) is professor and researcher at the Universidad Nacional de Quilmes, Argentina, and research member of the National Research Council of Argentina (CONICET).
