What is the significance of science?

"Science" cannot be accurately defined in short words. Generally speaking, science covers three aspects:

1. Observation: It devotes itself to revealing the truth of nature, and fully observes or studies the effects of nature (including ideological experiments), which usually means that it can be carried out by necessary methods or scientific methods-a set of procedures for evaluating empirical knowledge.

2. Assumption: It is assumed that the knowledge of the organization system is systematized through such a process.

3. Verification: To verify the reliability and validity of the research objectives.

Extended data:

Science includes basic science and applied science. Basic science only aims at exploring natural principles through experiments, and its achievements are generally not easy to be applied in a short time, such as physics, chemistry, biology, geology, etc. Applied science has both the motivation to explore principles and the motivation to pay attention to applications, such as medicine, pharmacy, applied optics, meteorology, science and technology archaeology, game theory and so on.

It stands to reason that science is different from pure technical discipline, which only involves making use of existing knowledge and principles to make inventions, bringing only technological changes, rather than new laws excavated from the principle level, such as engineering, forensic medicine, agronomy and forestry.

Applied science and pure technology are sometimes difficult to define. Because science and technology are often mentioned together, important technological developments are sometimes regarded as scientific achievements by the public. For example, one of the reasons why Yuan Longping failed to become an academician of the Chinese Academy of Sciences for three times is that hybrid rice is often regarded as an engineering achievement rather than a scientific achievement.

The public debate about whether Edison is a scientist is similar. Whether some disciplines focus on basic research or applied research may change with time.

For example, astrology, the predecessor of astronomy, serves for religious ceremonies and belongs to an applied discipline (not yet a science at that time); At present, astronomy is a science that focuses on basic research, but there are also a few technical applications that can bring substantive services (such as radio broadcasting and cell phone signals), such as launching space satellites. Astronomy may become an applied subject when interstellar migration and space resources development are realized in the future.
