Science the term “science’ has been derived from the Latin word, “scientia” that means “knowledge”. In the broadest of the sense, science implies an effort towards discovering and increasing human understanding regarding the working of reality.

The purview of science is actually that portion of reality that is not dependent on any religious, cultural, philosophical or political outlook. It is with the use of various controlled methods that the scientists of various fields collect valuable data in form of careful observations, record the observable physical-evidences of the natural phenomenon and the analyze information achieved for constructing theoretical explanations for the working of different things. It is through research that the scientists are able to gather valuable knowledge and information.

The procedure of research in science basically involves hypothesis generation, observations, experimentation and formulation of theories. The theories are then used to describe the human understanding for various physical processes that exist and facilitate active prediction.
