In Lesson 2, we explore the apparent motions of the planets, as well as attempts to explain these motions throughout history. Specifically, we explore the geocentric models of Aristotle and Ptolemy and the heliocentric models Aristarchus, Copernicus, and Kepler, culminating in Kepler’s three laws of planetary motion. We explore tests of these models by Galileo and others. Finally, we learn how Newton explained Kepler’s empirical laws with physical law and universal law. But we begin by exploring Stonehenge as an example pre-written-history astronomy, or archaeoastronomy.
