Kepler’s laws posit uncanny relationships. For instance, Kepler’s third law states that the square of the time of a planet’s revolution is proportional to the cube of its mean distance from the sun. How could anyone have figured that out? Kepler did in large part because he was convinced that there had to be a beautiful mathematical relationship there hidden andwaiting for him. Part of his Christian vocation was to find it and promulgate it to the greater glory of God. Kepler’s success leads to the surprising recognition that religious motivation can sometimes result in breakthrough discoveries that change the course of scientific history.
