What ancient technologies are still affecting our lives today?

Many ancient inventions, after improvements in ancient times, modern times and Chinese and foreign dynasties, are still in use, such as the four great inventions. Food-related categories include eating habits, chopsticks, pots and pans, etc. for those that have not been formed for a long time or basically do not need improvement. Violent tools are divided into stirrups, swords and halberds. Today, most basic life forms are based on ancient inventions, but there are some changes in expression.

Today's technology is basically developed from ancient inventions. Ancient China also made many explorations into nature, especially in astronomy and mathematics. The concept of "harmony between man and nature" in China's traditional culture emphasizes the relationship between "heaven" and "man" and "nature" and "man", so it attaches great importance to the observation and recording of various astronomical phenomena. Before modern times, China people have been the most diligent astronomical observers in the world. For example, since 6 1 1 year BC, every appearance of Halley's comet has been recorded.

Different from the geometric astronomical model based on this wheel in ancient Greece, China's astronomical calendar is based on long-term accurate observation and calculation, and adopts an equatorial coordinate system different from that in the west, which is not inferior in calendar calculation. At the same time, China's mastery of the movement of the sun and the moon is very subtle.

Ancient mathematics in China was based on decimal system for a long time, which was different from the axiomatic system of geometric deduction in ancient Greece. Its characteristic was programmed algorithm. For example, the "equation technique" of solving linear equations with algorithms and the achievement of solving many higher-order equations in Yuan Dynasty by Zhu Shijie's representative work "Siyuan Encounter" are regarded as the pinnacle of the development of China's preparatory system. In addition, Sun Tzu's problem of ordering soldiers, known as "Chinese remainder theorem", can also fully reflect the algorithmic characteristics of ancient mathematics in China. So it was influenced by ancient inventions, but the way of influence changed.
