Kepler and Modern Cosmology

Johannes Kepler has said, “I have cleared the Augean stables of astronomy of cycles and spirals, and left behind me only a single cartful of dung.” What he is describing as a cartful of dung is the non-uniform motion in non-circular orbits of the planets which could only be justified and explained by using arguments derived not from geometry, but from physics. His was the first serious attempt to explain the mechanism of the solar system in terms of physical forces, and it resulted in the formerly separate fields of physics and astronomy coming together.
