3 It is a reliable rule that when the author of a mathematical or philosophical work writes in vague and esoteric terms, he is talking nonsense. ―A.N. Whitehead
4 Mathematics makes an important contribution to the observation of nature by explaining the simple primitive elements in the regular structure from which the heavenly bodies are built. ——Kepler

6 If anyone does not know that the diagonals of a square and the same sides are incommensurable quantities, then he is not worthy of the title of human being. ——Plato
7 History makes people wise, poetry makes people intelligent, mathematics makes people precise, philosophy makes people profound, ethics makes people cultivated, logic and rhetoric make people eloquent. ——Bacon
8 After modern high-energy physics reaches quantum physics, many experiments cannot be done at all, and calculations can be done at home with paper and pen. This is not far from what mathematicians think, so mathematics is said to be in physics. It has incredible power. ——Qiu Chengtong
9 I always try my best to get rid of the heavy and monotonous calculations. —— Napier

The Story of a Mathematician
Li Shanlan attended a private school since she was a child and received a good family education. He was gifted, diligent and studious, and could recite the poems and books he read.
When she was 9 years old, Li Shanlan found a masterpiece of ancient Chinese mathematics - "Nine Chapters of Arithmetic" on her father's bookshelf. She found it very novel and interesting, and she became obsessed with mathematics.
At the age of 14, Li Shanlan relied on self-study to read the first six volumes of Euclid's "Elements of Geometry", which was a combination of Xu Guangqi (1562-1633) and Matteo Ricci (1522-1610) in the late Ming Dynasty. Translated ancient Greek mathematical masterpieces. The strict logical system and clear mathematical reasoning of Euclidean geometry are very different from the traditional Chinese mathematical thinking that emphasizes practical solutions and calculation skills. It has its own characteristics and strengths. On the basis of "Nine Chapters on Arithmetic", Li Shanlan also absorbed new ideas from "Elements of Geometry", which made his mathematical attainments increasingly sophisticated.
A few years later, as a student member of the prefecture and county, Li Shanlan went to Hangzhou, the provincial capital, to take the provincial examination. Because he "had dabbled in the study of speech, chapters, exegesis, but he was not as good as arithmetic, so he was very dedicated to arithmetic." Li Shanlan's preface to "Zegu Xi Zhai Arithmetic" resulted in poor writing of eight-part essays and failure. But he didn't mind at all. Instead, he took advantage of the opportunity in Hangzhou to search for various mathematics books, and bought back Li Ye's "Measuring the Circle" and Dai Zhen's "Pythagorean Circle". They studied it carefully and made him Mathematics level has been greatly improved.
Wu Zhaoqi, a native of Haiyan, said in his poem "Reading the Book of Chou People and Instructing Uncle Li Ren": "Everyone gathers in a gully, and Yazhi talks about arithmetic. There are sects in China and the West, and the diameter of the circle is extremely dense." "Exploration of the Three Unifications" It is difficult for others to understand the Chinese law. Yu Fang is very interested in learning and has a very single-minded ambition. "Xu Xiang's "Xichuan Shi Xuanchao" notes: "Qiuchong Wu Zhaoqi inherited the family education of Mr. Si Ting, and he lived in Xijie and Chongcha. His skills are particularly good. Li Renshu studied under him in Tongli." It seems that Li Shanlan once studied mathematics with Wu Zhaoqi as his teacher.
In his hometown, Li Shanlan organized the "Yuanhu Song Society" with Jiang Renrong, Cui Dehua and other relatives and friends. They often visited the "Dongshan Villa" and sang in different rhymes. At that time, he used the principle of proportionality of corresponding sides of a similar Pythagorean shape. Calculate the height of Dongshan. His Confucian classics teacher Chen Huan said in "The Origin of Teachers and Friends" that he "learns the art of nine numbers, always sets up table lines, and uses long and short forms according to festivals to measure the sun's scenery, which makes it easy to examine." Yu Mao said in "Baiyue Poetry" that he "sat on the top of the mountain to taste the dew at night to measure the latitude and longitude of the weather."
There is still a story in Li Shanlan's hometown that he stuck his head out of the attic window to observe the stars on his wedding night.
