To spell out this law of odd numbers more explicitly, let’s suppose the ball rolls a certain distance in the first unit of time. Then, in the next unit of time, it will roll three times as far. And in the next unit of time after that, it will roll five times as far as it did originally. It’s amazing; the odd numbers 1, 3, 5, and so on are somehow inherent in the way things roll downhill. And if falling is just the limit of rolling as the tilt approaches vertical, the same rule must hold for falling.
