3 Please briefly analyze the reasons for the development and subsequent decline of science and techn

The reason for the development of science and technology in ancient China is that most of the scientific and technological achievements have been achieved in practice. From the Shang and Zhou periods.

After the Spring and Autumn Period and the Warring States Period, Qin and Han Dynasties.

Northern and Southern Dynasties, Sui and Tang Dynasties.

To the peak of the Song Dynasty, ancient Chinese science and technology were constantly developing and improving.

The reason for the decline of science and technology in ancient China is that, compared with the West, China has not had a complete and correct scientific theoretical system in ancient times. As a result, practice cannot be guided by theory, which leads to the lack of stamina for the development of science and technology in ancient China.

In addition, since the Han Dynasty in our country has established Confucian humanist thought.

As a result, the thought of natural science could not be developed and eventually died out. Successive dynasties have included science and technology"Shinong Industry and Commerce"The third rank, called"Shaman.

100 workers", people who study science and technology have a low status. As a result, the development of science and technology in ancient China has not received due attention.

As one of the four great ancient civilizations, ancient China's outstanding and splendid cultural achievements are beyond the reach of other countries. However, the main reason for the backwardness in the later period was the feudal isolation of the country and the lack of communication with the outside world.

1. The scientific and technological content mainly focuses on agriculture-related agronomy, astronomical calendar and medicine, etc., with strong applicability, but the exploration of the development law of things is insufficient; In terms of research methods, it is mainly the collation of traditional classics, such as experience summarization, and lack of experiments; Attach importance to summarizing practical experience, and despise theoretical generalization and abstraction.

2. In the use of science and technology, it mainly serves the development of feudal agricultural economy and the needs of large-scale projects, and lacks the motivation and awareness to effectively transform science and technology into productive forces and become the further development of science and technology.

3. Pay attention to the exploration of social and humanistic issues, pay attention to the unity of nature and man, respect nature, and attach importance to improving the relationship between man and nature.

Because of the isolation of the country in the last years of the Qing Dynasty, China's news was backward, science and technology were stagnant, and there was no contact with new things.

can't keep up with the development of the times, caused by the isolation of the country, I really help you look forward to it

China is objectively a self-sufficient small-scale peasant economy, and its products (especially agriculture) are abundant, which means that with abundant human resources, it is difficult for China to have a demand for progress for the purpose of improving productivity. Therefore, it is not only the slow development of modern science itself, but also the fact that it ignores the early stage of modern technological progress in the West.

After the emergence of capitalism in China, the development was slow, and even until the end of the Ming Dynasty, the bourgeoisie still failed to become a climate at all. Not to mention that they have almost no appearance of primitive accumulation in the early stages of bourgeois development. Therefore, the premise of the West's primitive accumulation demand for maturing science and technology does not exist in China.

In the Ming Dynasty, it was still acceptable, but in the Qing Dynasty, because of the cowardice of the ruling class (after all, it ruled 400 million with 100,000), it raised ideological control to a new height. It has seriously hindered the normal dissemination of science and technology at the grassroots level.

Finally, China's ancient science and technology were developed, but most of them focused on practicality and lacked the rigorous theoretical logic of Western classical science. This is the most important shortcoming of China's ancient science itself.

Hieroglyphs are more difficult to spread than Western phonetics in terms of literacy and literacy. Objectively, it is very easy to cause social unrest, and soon there will be a fault line in some emerging technology culture. But this is the ultimate reason.

Of course, China actually has advantages over the West, such as natural and simple materialist beliefs (there was no integration of politics and religion after the Shang Dynasty), and a large national size (so once you concentrate your efforts, you will do great things beyond the imagination of others), but all these advantages need to wait for the main contradiction in our country to become the contradiction between the people's growing material and cultural needs and backward social production, and face up to this contradiction from top to bottom, so that China's science and technology can mobilize all the capabilities that can be mobilized. There has been a leap forward in science and technology!

1. Politically, the consolidation and development of a unified multi-ethnic state has been provided by the organization and support of a centralized state.

2. Economically, the high prosperity of the agricultural economy provides a solid material foundation.

3. The frequent economic and cultural exchanges between individual ethnic groups in ancient China and foreign exchanges also promoted the development of science and technology in ancient China.

4. The Chinese civilization has a long history and is the only ancient civilization in the world that has not been interrupted, which has created conditions for the inheritance of scientific and technological achievements.

5. The personal efforts and disdain of exploration and prudence of some famous scientists in ancient China were the subjective factors in the development of science and technology in ancient China.

China's ancient science and technology were very developed, which had a significant impact on the world.

For example, the invention of the compass had a very huge impact on the later world entering the Age of Discovery.

The introduction of paper-making and printing to other countries has led to the spread of their scholarship and knowledge of orange pants, and has contributed to the overall development of the world.

The invention of gunpowder was borrowed from foreign countries, and thus promoted the development of thermal weapons, changed the way of warfare, and changed the pattern of the whole world.
