Science is a method of gaining empirical knowledge of the physical world, systematically classifying and testing it, and trying to develop explanations, theories, and predictions that explain the cause and effect.  In science, special attention is paid to the regularity (regularity or pattern) seen in different events rather than a single event, and their explanation or clarification. 

There are two main fields of science: (1) the natural sciences and (2) the social sciences.  The natural sciences include astronomy, chemistry, physics, geology, etc., while the social sciences include sociology, economics, political science, anthropology, anthropology, etc.  Since sciences like mathematics and logic are not based on empirical facts, they are called formal sciences.  Similarly, engineering sciences, medical sciences etc. are considered as applied sciences.  Thus, since the subject matter of science is different, many branches of science have come into existence, but the study of each of these subjects has been done in a scientific manner, hence they are all known as science.

Physics is a basic natural science that studies the physical phenomena arising from the interaction of matter and energy in a natural or experimental situation.  The word physics is derived from the Greek word φυσικός (physicos = "natural"), which has the root φύσις (physis = "nature"). This is done on the role of scientific study, time and space.

Chemistry (Greek: χημεία) is a branch of science that studies the properties of elements and compounds, their composition and their structure and their transformations.  It also includes the study of the energy absorbed or released during the processing of matter.  Chemistry spans several disciplines, the main ones being: Organic Chemistry, Inorganic Chemistry, Physical Chemistry, Analytical Chemistry, Radio Chemistry, Biochemistry, Geosynthesis, Quantum Chemistry, Nuclear Chemistry and Chemical Spectrum in Chemistry.  It is said, but its true development is the French chemist a.  like this.  This happened after Lavoisier correctly interpreted the process of combustion.

Biology is the natural science related to the structure, function, evolution, distribution, identification, and classification of life and organisms.

Astronomy is the science of observing and studying the phenomena outside the Earth and its atmosphere.  Astrophysics is the branch of astronomy to study cosmology and space objects to study the origin and evolution of the universe.
