The worship of Taoist logarithm in catalog mathematics has a long history, especially the object number theory. Taoist techniques such as astrology, Taiyi, and armor avoidance all involve mathematical calculation methods, which promote the development of mathematics to some extent.
The abacus was first recorded in the numerology legacy. However, there has been controversy about the author of Shu Shu Ji Yi. Some experts in the history of science and technology believe that Xu Yue, who was born at the end of the Eastern Han Dynasty, was probably a reclusive Taoist priest. Some people think that Shu Shu Ji Yi was written and annotated by Zhen Luan of the Northern Zhou Dynasty.

There are few words about abacus in the book: "abacus, four-time control, latitude and longitude." This note briefly describes the structure of the abacus.
According to Ye Li, a mathematician in China13rd century, celestial art was handed down by "Master Dongyuan". Some experts in the history of science and technology believe that "Dong Yuan" was Li Sicong, a Taoist priest in the Song Dynasty (see resources). Li Sicong's Cave-in-the-Deep Collection first put forward that "nothing in the sky" and "the unknown can be expressed by unified symbols, so that it can participate in the operation like the known quantity", which is a breakthrough in mathematical thought and marks the birth of celestial art.
According to the relevant records in Zhu's The Enlightenment of the Book of Changes, experts in the history of binary science and technology believe that Shao Yong's Innate Changes and Zhou Dunyi's Tai Chi Tu originated from Taoist priests in the Five Dynasties and the early Song Dynasty, and therefore point out that Shao Yong is a figure influenced by Taoism. There are many contents related to mathematics in The Quiet History of Huang Ji. Shao Yong regarded the hexagrams in Yi-ology as abstract mathematics, and founded a school of mathematics with "innate Yi" as its core. Shao Yong's Four Pictures of Fuxi changed the Preface of the King of Wen's divination and replaced it with a new divination, which embodied the idea of dichotomy.
In the history of physics, Taoism once said that "by measuring the machine of heaven and earth, we can know the origin of nature" [1]. Taoism has produced many physical thoughts and achievements in its long-term observation, simulation and cultivation of immortals.
Optical track has a unique feeling and understanding of optical phenomena. There is a so-called "four rules" in the mirror classic in Bao Pu Zi Yuan Lan, which is called "four rules". "The first teacher used a ruler and a two-inch mirror to show the front, back and left, which is called' four rules'. Taoism believes that this is a fractal technology. The article "Bao Puzi. Inner chapter. "Truth" said: "A teacher keeps his promise and studies mirrors. His mirrors can be divided into dozens of people, and his clothes all look the same. "So Taoism has an understanding of the imaging principle of flat mirrors. In addition, the Shen Dan Jing of Taiying Jinye recorded the principle of convex lens, The Outer Chapter of Xuanzhenzi recorded the cause of rainbow and the method of making rainbow artificially, and The Fix True Calendar recorded the observation and graphic record of refraction and dispersion. The large-scale optical experiment carried out by Quanzhen Daochang Zhao Youqin has been highly valued by historians of science and technology.
Acoustics has its own understanding of acoustic phenomena and Taoism. Taoism believes that sound is produced by the vibration of qi, which is the so-called "empty valley foot sound" Taoism is famous for its emphasis on temperament. It is said that the Yellow Emperor ordered Linglun to compose music. "Take the dragon bell festival, take its uniform thickness. Break two parts, three inches and seven minutes, and blow the yellow bell ... The Yellow Emperor adjusted the qi of Yin and Yang to twelve rhythms. " "Adjusting Yin and Yang to Twelve Rhythms" means that sound is generated by Qi. Acoustics seen in Taoist books has made great contributions. For example, Huai Nan Zi has made a unique contribution to China's phonology. Shuhua has some descriptions of acoustic phenomena, which are quite valuable.
