Nature, in the broadest sense,                  is the natural,
physical,                            material world, or universe;
Nature can refer to phenomena of the physical world,

also to life in general. The study of nature is a large,

if not the only, 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 derived from the Latin word natura,
or "essential qualities, innate disposition",         &                                                              in ancient times,
literally meant "birth".      
   Natura is a Latin translation
of the Greek word physis (φύσις),           which originally
      related to the intrinsic characteristics that plants,
      animals &      other features of the world develop
of their own accord.      The concept of nature as a whole,
the physical universe,            is one of several expansions
      of the original notion;   it began with certain core
                                    applications of the word φύσις
                                       by pre-Socratic philosophers,
                  & has steadily gained currency ever since;
                  This usage continued during the advent of
 the modern scientific method in the last several centuries
