All set of knowledge of the person of the environment surrounding him, the world, the earth, water, the nature and other things has to take accurate place in a complex of other sciences and disciplines. To reunite all knowledge of this world accumulated by mankind, the special discipline - natural sciences was created.
Speaking generally, the natural sciences are the all reunited set of natural sciences which is considered in a uniform complex without restrictions. At the moment the natural sciences included such scientific disciplines as astronomy, physics, chemistry, biology, biochemistry, biophysics, geography, genetics, geology, radiobiology, radiochemistry. There is no confidence that over time the given science will not include a number of new disciplines. The natural sciences possess a number of the scientific purposes one of which - to disclose essence of the processes happening in the nature and to systematize the obtained data, and another is a finding of practical application received when performing the first purpose of knowledge. An ultimate goal of this discipline is development of the uniform concept of the world around which would not leave in itself disputed issues. Use of the gained knowledge first of all is possible in development of the new equipment. And it, in turn, attracts to development of social production. Social production is an economic category which, at first sight, not especially and it is connected with natural sciences. But this opinion is wrong, if to track all chain from opening before introduction, then it turns out that the natural sciences carry out an important public and social role in life and development of society at all stages of its existence. At some point, when scientific minds new data reveal and new discoveries appear, at once there has to be a question: and whether new opening by that which are already available at the disposal of scientists contradict? Therefore some of guarantees of successful functioning of natural sciences as sciences is an existence of open discussions and discussion of disputed issues, in a dispute the truth is always born. Distinctive feature of natural sciences is existence in it of the industries of scientific knowledge inseparable from each other. If from the uniform scientific concept to pull out any one discipline, then all meaning of existence of science of natural sciences will be lost.
