Why study scientific knowledge?
There are two purposes: one is practice and application; Another purpose is to explore and discover.
I. Practice and application
Learn the scientific knowledge summed up by human beings for thousands of years and apply it to social practice and national construction. This is what China people often say: "Let nature take its course". Let nature take its course is to apply the scientific knowledge summarized by human beings in the process of understanding nature to the process of developing nature, thus benefiting mankind. To act according to scientific knowledge is to let nature take its course.
Farmers planted crops according to the seasonal changes of the lunar calendar summarized by predecessors and the scientific methods summarized by agronomists, thus solving the problem of eating in the whole country.
Workers use the learned machine operation skills to accurately process various parts and assemble various modern machines according to the drawings designed by engineers, thus realizing today's modernization.
Engineers and designers applied the scientific knowledge summarized by predecessors to the design of machines and buildings, thus creating today's bustling cities and villages.
Teachers teach students the scientific knowledge summarized by predecessors, thus cultivating a group of national pillars.
……。
On the contrary, if we don't act according to scientific knowledge, it will violate the laws of nature and bring disastrous consequences. Today, the increasingly serious atmospheric greenhouse effect, abnormal tsunami, sea level rise, grassland desertification, ozone hole, etc., are all the results of human failure to act according to science.
Second, exploration and discovery.
It is to learn the scientific knowledge summed up by human beings for thousands of years and use it to further explore the mysteries of nature and promote the development of science and technology.
Among our teenagers, some students will be admitted to universities, graduate students, doctors and postdocs. After mastering a lot of scientific knowledge, they can use what they have learned to carry out scientific research. Scientific research is to reveal natural mysteries that have not been recognized by human beings, so as to sum up new scientific knowledge. These new scientific knowledge can guide mankind to effectively develop nature again. At the same time, new scientific knowledge can also guide mankind to reveal deeper natural mysteries. The development and progress of mankind is endless.
