I recall he said something about it being related to planetary motion in space.
If you have only 2 bodies, you can derive the equations of motion very easily and you get Kepler's laws.
But if you add a 3rd body, then there's no way to obtain their equations of motion and you must use numerical methods to calculate their motion step by step.

You mean increasingly unsubtle?
