The Actual Astronomy Podcast presents A History of Planetary Motion. In this episode we are joined again by Dave Chapman. Dave will review the history of our understanding of planetary motion, from prehistoric times and antiquity to the present day. He covers the contributions of Mesopotamians, The Greeks, Copernicus, Brahe, Kepler, Galileo, Newton, Halley, Lagrange, Laplace, Gauss, Le Verrier, Galle, Einstein, and Bretagnon. He concludes that our knowledge has progressed immensely, but in a way, we have come full circle!
