Scientific research originated in Sui Dynasty and matured in Tang Dynasty. Previously, in the Xia, Shang, Zhou, Spring and Autumn Period, nobles were hereditary, and ordinary people rarely had the opportunity to turn over. During the Warring States period, education developed and a hundred flowers blossomed, but only a few "scholars" were able to "sell to the royal family" by lobbying with their own knowledge and ability.

The Han Dynasty implemented the recommendation system and participated in social and state management. In fact, the imperial examination system in Sui and Tang Dynasties was a great progress in social development, which not only strengthened feudal rule, but also promoted social fairness and justice and was conducive to social stability. Therefore, the imperial examination system and its examination contents must ultimately conform to the political power of the ruling class. This also ensured the long-term continuation of China's feudal history.

And mathematical machinery, for the feudal society at that time, is obviously not necessary, and it is only the details at the end of the branch. How can it become the content of the national examination? According to the hypothesis of the topic, simple mathematical machinery has been greatly developed, social governance has not been stabilized and continued, and Chinese civilization may not be able to continue. The development of western history proves this point.

China didn't test articles in ancient times. But mathematics, physics, chemistry, machinery and other disciplines, which means that China has long been scientifically developed and has become a powerful advanced country in the world, and no outsiders dare to invade it. However, in any era, global science was at the limit of inferiority, and China Dynasty was at a weak level. Even with high technology and advanced talents, it is not enough for intruders to steal and kill.

Besides, there was no such research at that time, and no one could reach the goal. Since the late Qing Dynasty, China has been trampled and slaughtered at will. It was not until 1949 that People's Republic of China (PRC) was founded that China could quietly study science.

For example, countries such as the United States and Britain have never had a battlefield for hundreds of years. Invaders who engage in aggression and science and technology have never stopped, never stopped, improving and strengthening their national prestige, suppressing the human rights and national prestige of other countries and riding on other countries' heads. If there is no war in China, we will continue to train technical personnel. In order to pass these subjects, these talents are selected. Then China has long been a unique superpower in the world.
