>For alternative meanings, see nature (disambiguation). Nature (also called the material world, the material universe, the natural world, and the natural universe) is all matter and energy, especially in its essential form. Nature is the subject of scientific study, and the history of the concept is linked to the history of science. The English word derives from a Latin term, natura, which was in turn a translation of a Greek term, physis (φύσις). Natura is related to the Latin words relating to "birth", while physis relates to Greek words relating to "growth". In scale, "nature" includes everything from the universal to the subatomic. This includes all things animal, plant, and mineral; all natural resources and events (hurricanes, tornadoes, earthquakes). It also includes the behaviour of living animals, and processes associated with inanimate objects - the "way" that things change. See more at Wikipedia.org...
