In 1772, Johan Bode was the director of the Berlin Observatory in Germany. That year he published a numbers game the fairly well predicts how far the planets are from the Sun. This game involves doubling numbers, then adding four to each number with a final division by 10 (moving the decimal point to the left one place.) Though the math mentions no planet, it is amazing how well it predicts planetary distances. A new unit of distance is introduced for usage in the Solar System - the astronomical unit. The activity stresses that this is NOT really a law in science since the numbers do not fit perfectly. Still it is rather amazing that one can play a numbers game not related to astronomy and still have fairly close results.
