Nature (in the broad sense has a meaning equivalent to the natural world, the physical world, or the material world) refers to the phenomenon of the physical world and also life in general. The natural scale extends from subatomic to cosmic. The study of nature is a big part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena.
The word nature is a translation from the English "nature", which is derived from the Latin word natura, or "essential quality, innate disposition", and in ancient times, literally meant "birth". Natura is a Latin translation of the Greek word physis (φύσις), which was originally related to the innate characteristics possessed by plants, animals and various other features in the world
