Each of the sciences carried to type of natural has various stories of emergence and development therefore for clarification of this question natural sciences history as disciplines, generally is ordinary studied. But the main principle of the relation of certain spheres of scientific knowledge to "natural" is studying the natural phenomena, but not human society.
The sciences carried to "natural"
The basic list of similar disciplines looks as follows – physics, chemistry, biology, astronomy, geography and geology.
But eventually certain areas of these sciences adjoined therefore the following disciplines – geophysics, astrophysics, biochemistry, chemical physics, geochemistry, meteorology and many others were formed. Eventually they ceased to be considered as collateral and are already perceived as quite independent.
Interestingly and the fact that this list ordinary does not join the mathematics carried together with logic, to the category of "formal" disciplines which methodology differs from the category of "natural" radically.
Natural sciences history
According to the official history of this discipline, it appeared even more than 3 thousand years ago when ancient philosophers allocated three various sciences – physics, biology and geography. Then, apparently, quite household and prosy things, gave rise and to other disciplines. For example, trade relations and navigation – geography and astronomy, and improvement of specifications – physics and chemistry. Further, already in the late Middle Ages which are dated back to 14-15 centuries, scientists made an attempt of thorough revision of former antique representations and began to create so-called "new" natural disciplines. Emergence of elements of modern biology also belongs to the same time. The attempt of combination of the Aristotelean doctrine with Christianity became the main reason for such revision of the existing world picture in the Middle Ages. Such attempt failed therefore scientists were forced to refuse Aristotelian doctrines that became the trigger of emergence of the ideas about existence of emptiness, infinity of the nature, infinite space, not ideality of celestial bodies and the general possible irrationality. Englishman Francis Bacon who gave theoretical justification of the existing scientific technique in the work "New Organon" became the first theorist of natural sciences at the end of already 16th century. And further the given Descartes and Isaac Newton's opening which were constructed not on the speculative assumption, and on experimental knowledge finally broke off the "umbilical cord" connecting the scientific world with antique antiquity. The joint work "Mathematical Beginnings of Natural Philosophy" with publications of Pascal, Braga, Leibniz, Kepler, Boyle, Brown, Hobbes and many others became the culmination of these changes in 1687.
