Why is there traditional medicine but not traditional physics, traditional mathematics and tradition?

China's technology before and after the Ming Dynasty was world-class. The Silk Road spread them to the west, and western society was enlightened and developed, forming many academic theories. China was arrogant and backward, especially in the Qing Dynasty, which attached great importance to the rule of man and admired Buddhism and other religions, especially Confucius and Mencius. Many scientific theories were obliterated by the government. Moreover, because there are many people in China, the concept of friends of the same age is naturally deeply rooted, and many things are inseparable. They have not been carried forward or lost, and an education system will not be formed. But without China's compass and sundial, there would be no electromagnetic theory of physics and astronomy. Without China's bronze mirrors and musical instruments, there would be no optics and acoustics of physics. Without China's bronzes, wheeled vehicles, contradictory weapons and steelyard, there would be no mechanics, without China's Pythagorean theorem and abacus, there would be no mathematics. Without China's theory of infinite division of matter and gunpowder, there would be no atomic and molecular chemistry. Without China's papermaking and printing, the world would not be civilized.
