Ask for 2 stories of mathematicians, and the stories about mathematicians should be shorter

The story of a mathematician - Su Buqing.

Su Buqing was born in September 1902 in a mountain village in Pingyang County, Zhejiang Province. Although his family is poor, his parents are frugal and work hard to provide for him to go to school. When he was in junior high school, he was not interested in mathematics, thinking that mathematics was too simple and he could understand it as soon as he learned it.

However, a later math class influenced the path of his life.

It was when Su Buqing was in his third year of junior high school, and he was studying in Zhejiang Province No. 60 Middle School, and there was a teacher Yang who had just returned from studying in Tokyo to teach mathematics. In the first class, Mr. Yang did not talk about mathematics, but told stories. He said:

In today's world, the law of the jungle eats the strong, and the world's great powers rely on the strength of their ships and guns to carve up China. The danger of China's extinction is imminent, and it is a move to revitalize science, develop industry, and save the country. 'The rise and fall of the world is the responsibility of the husband', and every student here has a responsibility.

He talked about the great role of mathematics in the development of modern science and technology. The last sentence of the lesson was: "In order to save the world, science must be revitalized."

Mathematics is the pioneer of science, and in order to develop science, it is necessary to learn mathematics well. Su Buqing didn't know how many classes he had heard in his life, but this class made him unforgettable for life.

Mr. Yang's class deeply touched him and injected new stimulants into his mind. Studying, not only to get rid of personal difficulties, but also to save the vast number of suffering people in China; Studying is not only to find a way out for individuals, but also to seek a new life for the Chinese nation. That night, Su Buqing tossed and turned, unable to sleep all night.

Under the influence of Mr. Yang, Su Buqing's interest shifted from literature to mathematics, and since then he has set up the motto of "reading without forgetting to save the country, and saving the country without forgetting to read". As soon as he became obsessed with mathematics, whether it was a scorching summer or midwinter, a frosty morning or a snowy night, Su Buqing only knew how to read, think, solve problems, and calculate, and he calculated tens of thousands of number learning problems in 4 years. Now Wenzhou No. 1 Middle School (that is, the Provincial No. 10 Middle School at that time) still treasures Su Buqing's geometry exercise book, which is written with a brush and is neat.

When he graduated from middle school, Su Buqing's homework was above 90 points.

At the age of 17, Su Buqing went to Japan to study and was admitted to the Tokyo Higher Technical School with the first place, where he studied hungrily. The belief in winning glory for the country drove Su Buqing to enter the field of mathematics research earlier, and while completing his studies, he wrote more than 30 articles**, achieved remarkable results in differential geometry, and obtained a doctorate in science in 1931. Before receiving his Ph.D., Su Buqing was already a lecturer in the Department of Mathematics at Imperial University of Japan, but just as a Japanese university was about to hire him as an associate professor with a good salary, Su Buqing decided to return to China and return to his ancestors who raised him to teach.

Su Buqing, who returned to Zhejiang University as a professor, lived a very difficult life. In the face of the predicament, Su Buqing's "What is the benefit of hardship, I am willing, because I have chosen a correct path, which is a bright road of patriotism!" ”

This is the patriotic heart of the older generation of mathematicians.

Zu Chongzhi (April 20, 429 AD, 500 AD) was an outstanding mathematician and scientist in China. During the Northern and Southern Dynasties, the Han people, the characters were far away. He was born in the sixth year of Emperor Yuanjia of Song Wen and died in the second year of Yongyuan, Marquis of Qi.

His ancestral home is Fanyang County, Laishui County (now Laishui County, Hebei). In order to avoid the war, Zu Chongzhi's grandfather Zu Chang moved from Hebei to Jiangnan. Zu Chang once served as Liu Song's "master craftsman", in charge of civil engineering; Zu Chongzhi's father was also an official in the court.

Zu Chongzhi received scientific knowledge from his family since he was a child. When he was young, he entered the Hualin University and engaged in academic activities. In his lifetime, he successively served in the history of Southern Xuzhou (now Zhenjiang City), the government to join the army, the order of Louxian County (now the northeast of Kunshan City), the servant of the confessor, and the captain of Changshui.

His main contributions are in mathematics, astronomical calendars, and mechanics.
