Reminds me of how Kepler made his infamous discovery of elliptic orbits by staring at the data collected by his mentor Tycho Brahe. Without 20 years of detailed observations and calculations, Kepler probably would have either never come up with his theory or never have it taken seriously. And of course Newton’s principia devotes large portions to proving Kepler’s laws using Newton’s laws.
