The trajectory of an electron around the nucleus of an atom is not a stable path, and in measuring it one can only determine either its position or its impulse, never both. It is not possible to ascribe a particular speed and a particular location to any subatomic particle. Any prediction made about its behavior is therefore based purely on probability. At the macroscopic level—the level of human experience—this makes no difference to the prediction of future events because the aggregation of an immense number of probable outcomes at the subatomic level results in near certainty, but at the
