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:
“Criticism is infested with the cant of materialism, which assumes that manual skill and activity is the first merit of all men, and disparages such as say and do not, overlooking the fact, that some men, namely, poets, are natural sayers, sent into the world to the end of expression, and confounds them with those whose province is action, but who quit to imitate the sayers.”
—Ralph Waldo Emerson (1803–1882)
“I’ve been asked to give some words of advice for young women entering library/information science education. Does anyone ever take advice? The advice we give is usually what we would do or would have done if we had the chance, and the advice that’s taken, if ever, is often what we wanted to hear in the first place.”
—Phyllis Dain (b. 1930)
