Most systems above the molecular level involve so many parts and forces
and are so sensitive to tiny differences in conditions that their precise
behavior is unpredictable, even if all the rules for change are known.
Predictable or not, the precise future of a system is not completely determined
by its present state and circumstances but also depends on the fundamentally
uncertain outcomes of events on the atomic scale.
