What are the brilliant achievements of mathematics and astronomy in ancient China please give some examples of mathematical texts!

Mathematics and astronomy in ancient China had brilliant achievements. Mathematics originated from the early production activities of human beings and was one of the six arts in ancient China. The development of mathematics in ancient China can be divided into five periods: the budding period of the pre-Qin period, the foundation period of the Han and Tang dynasties, the heyday period of the Song and Yuan dynasties, the period of importation of Western learning, and the period of modern mathematical development. Examples are as follows:

1, Zhou Thigh Arithmetic: is China's earliest surviving mathematical text, written in the 1st century BC, mainly introduces the collinear theorem. Nine Chapters of Arithmetic: one of the most important mathematical works in ancient China, covering geometry, algebra, equations, and many other aspects.

2. Suffix: is an ancient Chinese arithmetic scripture, which mainly introduces the operation of fractions and the method of opening and leveling and other contents. Nine Chapters of the Book of Numbers: is an arithmetic scripture of the Tang Dynasty, which covers many aspects of arithmetic, algebra, geometry, and so on.

The Origins of Mathematics and Astronomy in Ancient China

1. In ancient China, mathematics and astronomy were closely connected. Due to the needs of agricultural production, people began to observe the stars, formulate calendars, and calculate the movements of the sun, moon, and stars, etc., which gradually formed a complete astronomical system. At the same time, these astronomical observation data also need to be processed and analyzed by mathematical methods, so mathematics also plays an important role in astronomy.

2. With the passage of time, mathematics and astronomy in ancient China continued to develop and improve. Zhang Heng in the Han Dynasty invented the Hun instrument and geodesic instruments, used to measure the rotation of the Earth and earthquakes and other phenomena; Li Ye in the Tang Dynasty put forward the "Tianyuan technology", that is, the use of algebraic methods to solve the geometric problems of the method; the Song Dynasty period of the invention of the "Qin Jushao algorithm "

3. Ancient Chinese mathematics and astronomy have a long history. According to "Zhou Thigh Calculating Classic", there was already accumulation and application of mathematical knowledge in the Western Zhou period of China around 1000 BC. And the origin of astronomy as an independent discipline can be traced back to the Xia Dynasty period.

4. In terms of mathematics, ancient Chinese mathematicians also invented many important mathematical methods and tools. For example, during the Han Dynasty, Liu Hui invented the "Circle Cutting Technique", that is, the method of approximating a circle with a polygon, which solved the problem of calculating the circumference of a circle; and during the Tang Dynasty, Wang Xiaotong invented the "Tianyuan Technique", that is, the method of solving geometrical problems by algebraic methods, which had a far-reaching influence on the later generations. The influence on later generations was far-reaching.
