Introduction to science:

It is an orderly knowledge system based on testable explanation and prediction of the form and organization of objective things, and it is systematic and formulaic knowledge. According to these (scientific) systematic knowledge, the fields to be reflected can be mainly divided into natural science, social science, thinking science, formal science and interdisciplinary science.

Science is an ordered knowledge system based on testable explanation and prediction of the form and organization of objective things, and it is systematic and formulaic knowledge. Its object is objective phenomenon, its content is formal scientific theory, and its form is language, including natural language and mathematical language.

Modern science is usually divided into three main branches: natural science (such as biology, chemistry and physics) that studies individuals and society, social science (such as economics, psychology and sociology) that studies abstract concepts, and formal science (such as logic, mathematics and computer science).

But whether formal science really constitutes a science is controversial, because they do not rely on empirical evidence. In addition, the discipline that uses existing scientific knowledge for practical purposes such as engineering and medicine is called applied science.

Science is based on research, usually in academic or research institutions and government agencies and companies. Scientific research affects the scientific policies of enterprises and countries by developing commercial products, armaments, health products and environmental protection.

Origin:

The earliest origin of science can be traced back to ancient Egypt and the two river basins (about 3500-3000 BC). They contributed mathematics, astronomy and medicine, which made Greece enter the natural philosophy of the classical era, thus formally trying to explain the natural causes of events on the basis of the material world.

Due to the demise of the Roman Empire, Greek knowledge disappeared in Western Europe in the early Middle Ages (400 to 1000CE), but these cultures are now preserved in the Muslim world. From 10 century to 13 century, Greek works were revived, and the study of natural philosophy in western Europe and Islam resumed "natural philosophy";

/kloc-The scientific revolution that began in the 6th century has changed the way of scientific research, and this scientific method will soon play a greater role. It was not until the19th century that the scientific functions of many institutions and professions began to take shape. In this era, "natural philosophy" has also become "natural science".
