Lesson 4: The Renaissance
1. Copernicus and the heliocentric system. Scientific and theological difficulties. The distinction between a real physical explanation and saving the appearances. Brahe and Kepler. The importance of precision. Kepler's determination of the orbit of Mars.
2. Galileo. The invention of the telescope and the observation of the satellites of Jupiter the mountains on the moon and the spots on the sun. Measurements of the motions of projectiles and of failing bodies. Opposition from the Aristotelian philosophers. Advocate of the Copernican system. Difficulties with the interpretation of Scripture.
3. Newton and the foundation of modern science. Synthesis of the rationalism of Descartes and the empiricism of Bacon. Laws of motion and theory of universal gravitation. The unification of terrestrial and celestial dynamics. The world as a machine and the theology of deism.
