Say I rolled a marble down a funnel so that it essentiallyspiralled into the center and fell through the funnel hole. Howwould you calculate the number of revolutions around the funnelthis marble made before reaching the center of the funnel? I'musing this similarity to find the amount of revolutions an electronwould make before it hit the nucleus of a hydrogen, but I can't forthe life of me think of a way to calculate number of revolutions ofan object traveling in a spiral towards a center.
