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 (or phüsis). 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.

Nature outside Earth and its atmosphere

Events and phenomena outside Earth and its atmosphere are in the natural science of astronomy.

Life

Life, the characteristics and behaviors of organisms, how species and individuals come into existence, and the interactions they have with each other and with their environment are all in the natural science of biology. The branch of biology that focuses on the relationships of organisms and their environment is the science of ecology.

Chemicals

The structure, properties, composition, and reactions of chemical elements and compounds are part of the natural science of chemistry.

Matter and force

The behaviour and interactions of matter and force are a part of the natural science of physics.

Earth

Everything relating to the planet Earth is a part of earth science.

Metaphysics

In philosophy, the view that the material world of atoms, animals, gravity, stars, wind, microbes, etc., actually exist independently of our observations of them is termed realism; the opposing view is called idealism.

The natural and the artificial

A distinction is often drawn between the "natural" and the "artificial" (="man-made"). Can such a distinction be justified? One approach is to exclude mind from the realm of the natural; another is to exclude not only mind, but also humans and their influence. In either case, the boundary between the natural and the artificial is a difficult one to draw (see mind-body problem). Some people believe that the problem is best avoided by saying that everything is natural, but that does little to clarify the concept of the "artificial". In any event, ambiguities about the distinction between the natural and the artificial animate much of art, literature and philosophy.

Another approach is to distinguish natural processes and artificial (man-made) processes. In this viewpoint, a process is deemed to occur either at the behest of man, or not. For example, flipping a light switch might illuminate a room, or perhaps a sunrise might illuminate that room. In this viewpoint, the sunrise would be termed a natural process; the decision of a human being to flip the light switch would be termed an artificial illumination, in contrast. In this viewpoint, artifice (art or literature) is clearly the result of willful human action; furthermore, the act of stating a philosophical position could also be a willful action (and hence at the behest of man), whether or not the content of the philosophy were to be about science.

The distinction between what is natural and artificial was initially important, as far as we know, to the ancient Greeks. Perhaps their main interest was in distinguishing good aims from ones that have been distorted.

Related concepts

The term natural science is used in a variety of ways, primarily:

• to denote the study of natural processes as opposed to human activities, in contrast to the social sciences; and
• to denote those sciences which employ the scientific method, in contrast, for example, to mathematics or computer science.

The term natural philosophy formerly named the scientific discipline now known as physics.

Natural theology straddles the disciplines of theology and philosophy of religion.

In education and related areas, the contrast "natural/artificial" can appear as " nature/nurture".
