quantum mechaincs

classical mechanics ( analogue ) that by throwing a marble at the moon a tiny but calculable shift occurs in the moon's position and that every marble thrown will produce a similar shft until a trillion marbles later an observable shift is noticed

quantum mechanics ( digital ) that no shift occurs until the trillionth marble has been thrown and enough energy has built up to cause a shift

or

classical mechanics ( analogue ) that as the sun's mass dissipates ( four million tons every second ) its gravitational pull on the earth decreases accordingly so that a gradual increase of the distance between the earth and the sun occurs micro second by micro second

quantum mechanics ( digital ) that no change in position can occur until a minimum energy exchange ( planck's constant or a multiple of it ) has taken place see also the flood
