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 science, natural and/or science:
““What we know, is a point to what we do not know.” Open any recent journal of science, and weigh the problems suggested concerning Light, Heat, Electricity, Magnetism, Physiology, Geology, and judge whether the interest of natural science is likely to be soon exhausted.”
—Ralph Waldo Emerson (1803–1882)
“If everybody is looking for it, then nobody is finding it. If we were cultured, we would not be conscious of lacking culture. We would regard it as something natural and would not make so much fuss about it. And if we knew the real value of this word we would be cultured enough not to give it so much importance.”
—Pablo Picasso (1881–1973)
“Today the function of the artist is to bring imagination to science and science to imagination, where they meet, in the myth.”
—Cyril Connolly (1903–1974)
