# Science

Science (from the Latin scientia, 'knowledge') is a system of acquiring knowledge based on the scientific method, as well as the organized body of knowledge gained through such research. Science as defined here is sometimes termed pure science to differentiate it from applied science, which is the application of scientific research to specific human needs.

## meaning

Science ( science ) first refers to the knowledge corresponding to the natural field, which has been expanded and cited to the fields of society and thinking, such as social science. It covers two aspects: Dedicated to revealing the truth of nature and making well-founded observation or research on nature. This observation usually refers to what can be made by necessary methods, or can be made by scientific method (English: Scientific method)-a set of procedures used to evaluate empirical knowledge. An organized system of knowledge obtained through such research. According to the Modern Chinese Dictionary (Dictionary Editing Office, Institute of Linguistics, Chinese Academy of Social Sciences, 1978), science is interpreted as:

Disciplinary knowledge system reflecting the objective laws of nature, society, thinking, etc. In line with science (spirit, method, etc.). Science is to discover all kinds of laws. The spirit of science is questioning, independence, and uniqueness, while the scientific method is logical, quantitative, and empirical. Scientific knowledge refers to the knowledge or knowledge system covering the operation of general truths or universal laws, especially those obtained or verified through scientific methods. Scientific knowledge is extremely dependent on logic.

## method

Three methods of contemporary scientific research:
1. Scientific Computing
Computational Science = Computational Mathematics + Computational Physics + Computational Chemistry
2. theoretical analysis
(E.g. mathematical analysis , physical analysis = theoretical physics , theoretical chemistry )
3. science experiment
(E.g. physics experiments , chemistry experiment )

## Classification

Fields of science are commonly classified along two major lines:
• natural sciences, which study natural phenomena (including biological life), and
• social sciences, which study human behavior and societies.
