What is scientific knowledge and what is the content of scientific knowledge?

Science is an orderly knowledge system based on testable explanations and the form, organization, etc. of objective things, and it is knowledge that has been systematized and formulated.

Modern science is usually divided into three main branches, the natural sciences (e.g., biology, chemistry, physics, etc.), the social sciences that study individuals and societies (e.g., economics, psychology and sociology), and the formal sciences that study abstract concepts (e.g., logic, mathematics, computer science).

But there is disagreement as to whether formal sciences really constitute a science because they do not rely on empirical evidence. In addition, disciplines that use existing scientific knowledge for practical purposes such as engineering and medicine are known as applied sciences.

Science is research-based and is usually conducted in academic or research institutions as well as ** institutions and companies. Scientific research influences the science policy of businesses and countries through the development of commercial products, armaments, health care products and environmental protection.

The role of science and technology

1. Social progress.

The productive forces developed by science and technology have created a highly developed material civilization, but the improper use of science and technology has caused extremely serious environmental problems around the world.

2. Economic development.

China's labor productivity is only 1,40 of that of developed countries. Once science and technology are transformed into productive forces, they will greatly improve production efficiency and thus promote rapid economic development, and their role greatly exceeds the role of capital and labor in transforming the economy.

3. Military combat effectiveness.

In today's world, peace and development are the main themes of the times. However, the "cold war" mentality still exists, and hegemonism and power politics are still the main source of threats to world peace and stability. Becoming a strong country in science and technology has become the common choice of modern countries.
