Natural sciences are characterized by their methods, approaches and objects of research.

Natural sciences are a complex of sciences, based on natural phenomena of nature, without the intervention of the human factor; Section of science.
Traditionally, the natural sciences include such disciplines as geography, biology, chemistry, physics, astronomy, geology.
Natural sciences are characterized by their methods, approaches and objects of research, different from others.

The basis of the natural sciences is the study of nature, its laws and patterns of development, the fundamental role in the study of which observation plays. On the basis of this method, from the earliest times, a man collected knowledge about the world around him, analyzed and systematized them, in order to use them later for their needs. The great contribution made through observation and became the basis for all subsequent studies was made by such great scientists of antiquity as Aristotle, Plato, Pythagoras, Herodotus and many others. However, for deeper, inner knowledge and revealing the essence of all the phenomena occurring, one observation was not enough, and the person began to conduct experiments. One need only recall the endless experiments with materials and substances that the alchemists did in an unquenchable desire to find the elixir of eternal youth, the philosopher's stone and other miraculous substances, in pursuit of which so many discoveries were made. Or remember names like Christopher Columbus, Isaac Newton, Vasco da Gama, Einstein, Galileo Galilei, Fibonacci, Magellan - they were all enlighteners and promoted science, often even at the cost of their own lives. But despite of any obstacles, natural sciences continued and continue to develop, because they are always relevant and necessary. Through their study, humanity can more fully meet their needs, finding new ways to solve problems. Thus, natural sciences are characterized by progress and are the driving factor of development.

In general, studying nature, man has always been guided primarily by the analytical approach, in other words, by the method of reductionism (from Latin reductio - reduction). So, trying to explain one phenomenon, we are forced to consider its separate parts, constituent units. To explain the physiology of the human body, we turn to its structural components: the organs that make up their cells and eventually come to some indivisible part, the starting point of existence. Through the knowledge of the microworld, we discover the universe for ourselves.

All this led to a multiple stratification of all the so-called fundamental sciences into separate disciplines, as well as "borderline" sciences, which are at the junction of the main directions. Nevertheless, all sciences remain interconnected, new branches of various disciplines arise through their assimilation and interaction, hierarchy and systematization appear. Due to this, natural sciences are characterized by interpenetration and orderliness.

In addition, natural sciences actively interact with other branches of natural science: technical, applied, social. This is especially intense with the latter, since natural and social sciences have similar methods and a common object of research - a person who is part of the society and part of nature.

Bionics appeared at the junction of the natural and technical sciences .
A unique, interdisciplinary science, which includes technical, natural and socio-human sciences, is ecology.
From all of the above, we can conclude that natural science is characterized by many factors, the main of which are their direct connection with nature, deep significance and interconnectedness.
