Su Buqing, a famous master of mathematics, returned to China with a doctor of science from Imperial University of Northeast Japan at the invitation of Chen Jiangong, a famous mathematician, in March 1931. He was employed by National Zhejiang University and successively served as an associate professor, professor, dean, supervisor and provost of the Department of Mathematics. By October 1952, due to the adjustment of colleges and departments in colleges and universities across the country, he was a little reluctant to be a professor and head of the Department of Mathematics at Fudan University in Shanghai, and later served as provost, vice president and principal. He has served as a member of Chinese People's Political Consultative Conference for many times, a deputy to the National People's Congress, and vice-chairman of the 7th and 8th Chinese People's Political Consultative Conference and vice-chairman of the NLD Central Committee.

Looking back at Su Buqing's century-long life, it is also rugged and muddy, with many stories. Here are a few to comfort readers.

Story 1

On September 23rd, 192, it was an ordinary day, but for Su Zushan's family whose ancestors fled from Tongan, Fujian to Daixi Village, Pingyang, Zhejiang, it was a rare day of great joy and good luck. God knows, heavenly god blesses the people. Su Zushan's family added a ding, and the couple laughed from ear to ear, and finally had a "successor" who had been farming for generations. But Su Zushan and his wife never went to school at the end of the year, and they tasted the bitterness of being uneducated. They were eager to succeed, so they chose the name "Buqing" for their son, and the fortune teller also said something nice. In the name of "Buqing", they will definitely be able to "rise to the top, honor their ancestors" in the future.

after all, a name is not a ladder of fame and fortune. Just as his peers were carrying schoolbags to school, Su Zushan gave his son a bullwhip. From then on, Su Buqing wore a big bamboo hat made by his father and a coarse cloth sewn by his mother. He rode barefoot on the back of a cow and came to the foot of Woniu Mountain with a wave of his whip. Su Buqing's family is a big buffalo, fat and strong, and he never takes short and small cowherd babies seriously. Once, when the buffalo got angry, it ran and jumped, throwing Su Buqing into a bamboo garden that had just been cut. Blessed by God, he fell among several bamboo roots and escaped without suffering.

herding cattle home, Su Buqing walked past the gate of the village private school and was often attracted by the sound of books. Once, the teacher was reading aloud: "Su Laoquan, twenty-seven, began to get angry and read books." After listening to it, he read it several times. Since then, he has remembered the jingle and sang in the mountains when herding cattle.

Su Zushan often listens to his son recite the Classic of Three Characters and Hundred Family Names, and he is puzzled. On one occasion, I happened to see my son "eavesdropping" at the gate of the private school. My father's heart finally moved. As soon as the husband and wife got together, they decided to tighten their belts and sent Su Buqing to the private school.

Story 2

At the age of 9, Su Buqing's father took a load of rice as tuition, walked 5 kilometers of mountain roads, sent Su Buqing to Pingyang County, and became a transfer student in a high school. From the mountains to the county seat, Su Buqing was an eye-opener, and everything was novel. The first time he saw minced meat in the steamed bread, he often changed his meal ticket into money to buy "meat steamed bread" to eat. A month's meal ticket was used up early, so I had to go hungry. He was amused when he saw the tiger stove where the water was boiling. He threw the eggs brought from home into the pot, and a pot of boiling water turned into a pot of egg drop soup. When the boiler saw it, he caught him and beat him.

Su Buqing plays and plays all day. He often takes the "red chair" in exams. By the end of the final exam, he won the last place in his class. However, his composition is not bad. The "eavesdropping" in the private school stimulated his interest in learning Chinese and laid a little foundation for his composition. However, the more Chinese teachers read it, the more they don't believe it. They always think that Su Buqing's composition is copied. Therefore, he was awarded a very low score. In this way, his stubbornness was even more aroused. The more the teacher said that he was not good, the less he studied hard. For three semesters in a row, he was the last one. Both classmates and teachers said that he was a "fool".

Once, geography teacher Chen Yufeng called Su Buqing to his office and told him a short story: "When Newton was 12 years old, he transferred from a rural primary school to a city to study, and his grades were not good, so his classmates looked down on him. Once, a classmate bullied him rudely and kicked him in the stomach. He rolled in pain. That classmate is better than him in health and homework, and Newton is usually afraid of him. But at this moment, he couldn't bear it, jumped up and fought back, forcing the classmate into a corner and pressing on the wall. The classmate saw that Newton was so brave in his anger that he had to give in. Newton's reason for learning from this incident is only so much: as long as you make up your mind, you can subdue it. He worked hard and worked hard, and soon his grades jumped to the top of the class, and later he became a great scientist. "

Su Buqing was grateful to see that Mr. Chen didn't criticize him and told him stories. Teacher Chen saw him hang his head, touched his head and said, "I think you are a smart child. If you are willing to work hard, you can definitely get the first place in the exam." He added, "Your father and mother have worked hard and saved money. I hope you can read the book well. As you are now, what will you repay them in the future? " Su Buqing couldn't hold back the shock of his heart any longer. Tears streamed down his chest like broken pearls, and he felt that he had done something wrong for the first time. Since then, he has completely become a sensible child, stopped playing and studied hard, and won the first place in the class in the final exam.

Story 3

A math class in Zhejiang No.1 Middle School in Wenzhou led Su Buqing to the road to the kingdom of mathematics. Teacher Yang, who returned to Wenzhou from studying in Japan, was in math class with the true feelings of worrying about the country and the people: "In today's world, the law of the jungle prevails. The world powers rely on the ship to build a strong gun, carve up the beans in China, and devour them. The danger of national subjugation and extinction of the Chinese nation is imminent. In order to save the nation and survive, we must revitalize science. Mathematics is the pioneer of science. In order to develop science, we must learn mathematics well. " Teacher Yang's words touched Su Buqing's heart. Since then, his interest has shifted from literature to mathematics. Once, Su Buqing proved a geometric theorem in 2 different ways. When President Hong Min first learned, he called Su Buqing to the office, patted him on the shoulder and said, "Study hard and send you to study abroad in the future." By the time he graduated from Su Buqing Middle School, President Hong had been transferred to the Beijing Ministry of Education, but he was still concerned about Su Buqing's study and sent 2 yuan to help Su Buqing study abroad.

In p>1919, at the age of 17, Su Buqing bought a boat ticket to Japan, and it was really difficult for him to live for three months with 17 yuan money. He can only eat two meals a day, and has no money to hire a Japanese teacher, so he has to learn from the landlord. Finally, he answered the examiner's questions in fluent Japanese, and entered the famous school-the Department of Electrical Engineering of Tokyo Institute of Technology with the first place. In 1924, he was admitted to the Department of Mathematics of Imperial University in Tohoku, Japan with the first place, and studied under the famous geometer Professor Tadashian Wata. In 1927, after graduating from college, he sold newspapers, delivered milk, worked as a magazine proofreader and tutor after school, and used the money he earned to pay tuition fees, so he was promoted to the graduate school of the school as a graduate student without examination. With a strong will, he studied hard and published 41 research papers on affine differential geometry and projective differential geometry, which opened up a new field of differential geometry research and was called "a brilliant mathematical star rising from the Eastern countries" by the mathematical community. In March, 1931, he won the Doctor of Science degree with excellent results, becoming the second foreigner to receive this degree after Chen Jiangong. Since then, offers at home and abroad have been flying like snowflakes, and Su Buqing declined them one by one. Because two years ago, when Chen Jiangong received his Ph.D. in Science, he asked Su Buqing to go to Zhejiang University with poor conditions. Su Buqing said, "You go first, and I'll come back after graduation. Let's spend 2 years to make the Department of Mathematics of Zhejiang University a first-class department in the world ... "This may be Su Buqing's reluctance to leave Zhejiang University when the departments of colleges and universities in China are adjusted.

After taking up his post, Su Buqing has made brilliant achievements in scientific research and teaching. Except for the quartic (third-order) algebraic cone discovered when he was a graduate student, he was praised as the Su Cone by the academic circles, and later he worked in the theory of projective curves, the theory of projective surfaces, the theory of yoke net in high-dimensional projective space, the differential geometry of general space and calculation. He also proved that the closed Laplace sequence and structure (T4) are known as "Su (Buqing) chain" by the world academic circles. Therefore, the famous German mathematician Brasuke called Su Buqing "the first geometer in the East", and mathematicians in Europe, America and Japan called him and his colleagues "Zhejiang University School". Indeed, from 1931 to 1952, Su Buqing trained nearly 1 students, of whom 25 were the dean and deputy dean in more than 1 famous universities in China, and 5 were elected as academicians of China Academy of Sciences. Even after liberation, there were 3 academicians trained and 8 academician students. In Fudan Institute of Mathematics, there are Gu Chaohao, Hu Hesheng and Li Daqian in Su Buqing, which is a rare and gratifying phenomenon.

Story 4

After the July 7th Incident, Zhejiang University was forced to move westward. At the head of this national disaster, Su Buqing received an urgent telegram: Mr. Matsumoto, his father-in-law, was critically ill and asked Mr. and Mrs. Su Buqing to go to Sendai for the last time. Su Buqing handed the telegram to his wife and said, "... you go, I want to stay in my own country." Su Buqing's wife Su Songben said, "I'll follow you." However, because his wife had just given birth and could not move in with him, Su Buqing sent his wife to Pingyang for refuge in the countryside. It was not until the summer vacation of 194 that the president of Zhu Kezhen granted a special passage fee to his wife and daughter to Meitan.

In Meitan, the life of teachers and students was extremely hard, and university professors could hardly make ends meet on their salaries. Su Buqing bought a hoe, and every day when he came home from work or had a rest day, he opened up wasteland to grow vegetables. On one occasion, the vegetable hall of Meitan Restaurant could not supply it, so he had to go to several baskets of cauliflower from the vegetable field in Su Buqing. Another evening, President Zhu came to the ruined temple where he lived and saw Su Buqing carrying water to grow vegetables, while Su Songben was cooking with his son on his back. Careful President Zhu asked Su Buqing when he saw that the pot was full of radishes and dried sweet potatoes. Su Buqing explained: "My family has many children, and my salary is not enough to buy rice. Dried sweet potatoes dipped in salt have been eaten for several months. " Zhu Kezhen was amazed. So, he chartered Su Buqing's two middle school sons to make an exception and eat in middle school and live at home (because Sue's family couldn't come up with bedding).

The difficulties in life are getting worse and worse. A young son in Su Buqing died soon after he was born because of malnutrition. Su Buqing buried him in the mountain of Meitan, and engraved the words "Su Ying's Tomb" on the small stone tablet. However, the difficulties in life can't scare people with will and perseverance, and teaching and scientific research in Zhejiang University are still proceeding in an orderly way. Su Buqing also took to the podium with difficulties. When he turned around and drew geometric figures on the blackboard, the students would talk about the "triangle, trapezoid …" patches on Teacher Su's clothes and the "spiral curve" on his ass! In the evening, Su Buqing put the tung oil lamp on the incense table of the ruined temple to write teaching materials, and finally completed the book Introduction to Projective Curves with his perseverance. In the summer of 1994, the author was lucky enough to see the small temple where Su Buqing lived during his migration in Qingyan, and a feeling of reverence was born and unforgettable.

Story 5

On December 7, 1972, Zhang Sucheng, a student and famous mathematician in Su Buqing, visited mathematicians from all over the world for the need of the resumption of the Journal of Mathematics. He was supposed to visit Mr. Su when he went to Shanghai. Unexpectedly, in the book Introduction to Projective Geometry (English version) given by Mr. Su, he wrote a poem on the title page:

Thirty years ago in Guizhou.

This not only breaks the common saying of inscription, but also tells the whole story about the feelings of teachers and students, which shows that Su Lao's poetic skills are superb and his literary skills are profound.

Many people know that Su Buqing is a master of mathematics, but they don't know that he is also a master of literature, a great writer and a poet. He loved ancient poetry since he was a child and learned to write poetry at the age of 13. When I was a child, I often rode on the back of a cow and read Poems of a Thousand Families. For decades, he kept company with poetry and walked with poetry books. Every time he went on a business trip, he always put one or two books of poetry in his bag, such as Selected Poems of Du Fu. Su Buqing not only reads poetry, but also has an interest in writing poetry. He has been writing for decades and has written nearly a thousand poems. When he was 96 years old, Su Buqing Amateur Poetry Banknotes was published by Beijing Qunyan Publishing House, and 444 modern poems with 6 words were collected by Su Lao, among which 191 works from 1931 to 1949 included 47 words. From this, we can appreciate the light reflected by Su Lao's academic career and poetry and calligraphy skills in the past 6 years, which is full of the flavor of the times and gives people a lot of enlightenment.

recalling the period when Zhejiang university moved to Meitan, he and Qian Baoyu, a master of mathematics, founded Meitan Yinshe, and under extremely difficult living conditions, he published the First Collection of Poems of Meitan Yinshe at his own expense, which contained about 1 poems of various schools. In the days of national disaster, poets often drink tea and recite poems, or discuss doctrines, or comment on the current situation, and their feelings of worrying about the country and homesickness are often revealed in their writings.

In p>1944, Su Buqing wrote a poem on the theme of "Visiting the Seven-Seven Pavilion":

Climb the path with a single coat, and a stick crosses the lantern pavilion.

both trees protect the road, and there are seven seven pavilions near the river.

visitors are old because they travel far away, and mountains are green in their hometown.

there is no tears in the north, and the Central Plains is bloody.

This is Su Bu's token of affection with things, his nostalgia for the fall of his hometown and the broken mountains and rivers of his motherland, and the praise of the people's rise to the war of resistance. The feelings of patriotism and concern for the world flowed from his heart.

Su Buqing's poetic skills are superb and breathtaking. His poems are lofty in artistic conception, fresh in style, full of allusions and philosophy.

Reading many of Su Buqing's poems not only makes people feel that Su Lao often inculcates the importance of the "pyramid" foundation for later learning, but also makes people feel that the arts and sciences are interlinked. For decades, he skillfully used his self-proclaimed "odd bits and pieces" (odd bits and pieces of time) to study and study. Aren't these good poems that will remain in the world forever evidence that Su Buqing made full use of odd bits and pieces of time?
