China ancient science and technology development is divided into several periods? What are their characteristics?

The development of ancient science and technology in China can be divided into the following periods, with the following characteristics:

1, Spring and Autumn Period and Warring States Period. During this period, different theories sprang up like mushrooms after rain, and a large number of thinkers and philosophers lobbied around and argued with each other, forming a literary talent with a hundred schools of thought contending.

2. From Qin and Han Dynasties to Southern and Northern Dynasties. This period formed the pattern and road of China ancient practical science and technology, and made an important contribution to China's later scientific development.

3. Tang and Song Dynasties. This period is the peak of the history of science and technology in China. If the Tang Dynasty was a pioneering period of many sciences and technologies, then the Song Dynasty was a fruitful period.

4. Ming and Qing dynasties. During this period, both scientific knowledge and technological creation have been developed, in contrast, technological creation is more prominent. But as far as the scientific forms and methods of scientific research are concerned, there is no essential difference between them.

In human history, the highest achievement of science and culture in feudal society was created by China. Among them, agronomy, medicine, mathematics and astronomy were the four natural sciences in ancient China. From the Shang and Zhou Dynasties, through the development of the Spring and Autumn Period, the Warring States Period, the Qin and Han Dynasties, the Southern and Northern Dynasties, the Sui and Tang Dynasties, and the Song Dynasty, the ancient science and technology in China was constantly developing and progressing. During the Ming and Qing Dynasties, influenced by foreign policies such as sea ban and closed door, China's ancient science and technology declined, and western science and technology was introduced to China.

Characteristics of the development of ancient science and technology in China;

(1) China ancient science and technology is practical, serving the needs of production and consolidating its rule.

(2) Most ancient scientific and technological works in China are direct records of production experience or intuitive descriptions of natural phenomena, which are very empirical.

(3) The technicalization tendency of ancient scientific theories is serious, and these technologies are not open and have not been transformed into universal productive forces.

In a word, China's ancient science and technology had a great influence on the world and made great contributions to the world's science and technology.
