“Science” is an orderly knowledge system based on test -available interpretations and the form of objective things and organizations. It is a systematic and formalized knowledge.The fields that reflect the objects to be reflected in these (scientific) system knowledge can be divided into natural sciences, social sciences, thinking science, form science and cross -science.
Modern science is usually divided into three main branches, natural sciences (such as: biology, chemistry and physics, etc.), studying the social sciences of individuals and society (such as economics, psychology, and sociology), as well as the form of studying abstract conceptsScience (such as logic, mathematics, computer science).But whether formal science really constitutes a science is different because they do not rely on empirical evidence.In addition, disciplines that use existing scientific knowledge in actual purposes such as engineering and medicine are called applied science.
Science is based on research and is usually carried out in academic or research institutions, government agencies and companies.Scientific research affects the scientific policies of enterprises and the country through the development of commercial products, arms, health care products, and environmental protection.
