What is Science?

Science is nothing but it is getting the deep knowledge of nature and natural phenomena. In other word the deep and systematic study of whatever happens in this physical world is called science. 

The word science is derived from the Latin verb ‘scientia’ which means ‘to know’. The Sanskrit word vijnana and the Arabic word Ilm convey the similar meaning, namely ‘knowledge’.

The knowledge which humans have collected through their observations and experiments, when organized systematically is called Science.

The different definitions of Science given by various scientists are:

Albert Einstein: Science is not just a collection of laws, a catalogue of unrelated facts. It is a creation of human mind. With its freely invented ideas and concepts.

Bruce Lindsay: Science is a method of describing, creating and understanding human experience.

Neils Bohr: The task of science is both to extend the range of our experience and to reduce it to order.

Gerald Holton: Science is ever unfinished quest to discover all facts, the relationship between things and the laws by which the world runs.

Science is divided into many branches:

Physical Sciences: The Science in which we study about non living things is called physical sciences. For example, Physics, Chemistry, Geology, Astronomy, Geography, Astrology, Oceanology etc.

Biological Sciences: The science in which we study about the living things is called Biological Sciences. For example, Botany, Omithology, Anthropology, Entromology, Zoology, Forensic science etc.
