During the cold war, there were a lot of exaggerated propaganda, all of which served politics. The depth of drilling is nothing more than a little hotter underground, and there will be no special sounds and screams. After the disintegration of the Soviet Union, this research stopped.
This tells us that we still have to believe in science.
There are five main reasons for believing in science:
Rationality and objectivity: Scientific research is not based on "gods", "ghosts", "immortals" and "gods" (some scientists still believe in religion, and "science" itself is the result of rational thinking. ), everything is based on the observation of objective facts. Usually, scientists will design experiments and control various variables to ensure the accuracy of experiments and the ability to explain theories.
(2) falsifiability: This is karl popper's view. In fact, human beings can't know whether the theory in a science is necessarily correct. If there are some mistakes in this science, and people can prove that these mistakes are indeed wrong rigorously and clearly, then this science is considered to be scientific.
There is a scope of application: that is, it is not necessarily an absolute truth that is universally applicable. For example, general relativity fails in the micro world, and quantum theory fails in the macro world. However, scientists are still trying to find and explore whether there is a theory that can cover all natural phenomena (at least in the physical world, combining relativity with quantum mechanics is an ambition that lasts for at least several decades. )。
④ Universal inevitability: Scientific theory comes from practice and must return to practice. It must be able to explain all the known facts within its scope of application.
⑤ Science can be divided into theory, application and other levels.
⑥ In the interaction with social progress, the guiding role of science in practice is constantly strengthened, and the scientific system itself is also growing, which has a great influence on human history.
