Nature, in the broadest sense, is equivalent to the natural world, physical world, or material world. “Nature” refers to the phenomena of the physical world, and also to life in general. It ranges in scale from the subatomic to the cosmic.The word nature is derived from the Latin word natura, or “essential qualities, innate disposition”, and in ancient times, literally meant “birth”. Natura was a Latin translation of the Greek word physis, which originally related to the intrinsic characteristics that plants, animals, and other features of the world develop of their own accord.
