Natural Science
An example of a stochastic process in the natural world is pressure in a gas as modeled by the Wiener process. Even though (classically speaking) each molecule is moving in a deterministic path, the motion of a collection of them is computationally and practically unpredictable. A large enough set of molecules will exhibit stochastic characteristics, such as filling the container, exerting equal pressure, diffusing along concentration gradients, etc. These are emergent properties of the systems.

Famous quotes containing the words natural and/or science:
“Some natural tears they dropped, but wiped them soon;
The world was all before them, where to choose
Their place of rest, and Providence their guide;
They, hand in hand, with wandering steps and slow
Through Eden took their solitary way.”
—John Milton (1608–1674)
“The essence of acting is the conveyance of truth through the medium of the actor’s mind and person. The science of acting deals with the perfecting of that medium.”
—Minnie Maddern Fiske (1865–1932)
