19101012 was born in a small businessman's family in Jintan county, Jiangsu province, with a height of1.65m. My father Hua Ruidong runs a small grocery store, and my mother is a virtuous housewife. Hua was born when his father was 40. At the age of 40, the couple regarded their son as the apple of their eye. In order to bless their son, they buckled two baskets for him when he was born. Therefore, Hua got its name. After graduating from Renmai Primary School at the age of 12, he entered Jintan County Junior High School and fell in love with mathematics. One day, the teacher worked out a math problem of "I don't know the number of things". The teacher said that this is a famous math problem in Sun Tzu's Art of War: "Today, there are things I don't know the number of. Three or three numbers leave two, five or five numbers leave three, and seven or seven numbers leave two. What is the geometry of things? " "23!" As soon as the teacher spoke, Hua blurted out his answer. At that time, Hua had not learned Sun Tzu's calculation. He thought in the following wonderful way: "three-three numbers leave two, seven-seven numbers leave two, and the remainder is two." This number may be 3×7+2=23, and 5 divided by exactly 3, so 23 is the number you want. " Hua denied that he was a genius. 1925 after graduating from junior high school, he was unable to enter senior high school because of his poor family, so he had to study accounting in the Chinese vocational school founded by Huang Yanpei in Shanghai, in order to find a job similar to accounting to support his family. In less than a year, due to the high cost of living, I was forced to drop out of school and go back to Jintan to help my father manage the grocery store. In the monotonous life of standing at the counter, he began to teach himself mathematics. When he returned to his hometown, he continued to study mathematics while working for his father in a grocery store with only a small facade. Recalling the time when he studied hard, his sister Hua Lianqing said, "Although it was winter, Luo Geng was still reading his math book at the checkout counter. Snuff running down, he wiped his nose with his left hand and threw it aside. He didn't get rid of it, so he stretched out his right hand and kept writing ... "
At that time, Luo Geng stood in front of the counter. When the customer came, he helped his father do business, do abacus and keep accounts. As soon as the customer left, he buried himself in reading and solving math problems. Sometimes I am in a daze, forget to receive the customer, and even take the calculation result as the payment payable by the customer, which surprises the customer. Because similar inexplicable things often happen, after a long time, his neighbors treat him as a joke, and everyone has nicknamed him "Luo Daku". Whenever something happens that neglects customers, my father is angry and anxious, saying that he is too tired to read the "heavenly book" and wants to burn the book forcibly. When there is an argument, Hua always clings to the book.
Later, recalling this life, he said bitterly: "It was a year when I should receive education, but the word' poor' deprived me of my dream: wiping my nose, a pair of straw sandals and a cigarette, a roll of rush grass and a needle in the northwest tuyere, struggling to survive." Stubborn self-study to 18 years old. /kloc-married Wu Xiaozhi in the autumn of 0/927. From 65438 to 0929, Hua was employed as a clerk in Jintan Middle School and began to publish papers in Shanghai Science and other magazines. 1929 In the winter, he suffered from severe typhoid fever. After nearly half a year's treatment, he recovered, but his left leg joint was seriously damaged, leaving him with a lifelong disability. He had to walk on crutches.
In fact, when Hua was in junior high school, his homework was not good once, and sometimes he failed in math. Hua's math teacher, a famous educator and translator in China (1900 was born in Jintan), was teaching in Jintan Middle School at that time. He found Hua playful, but quick-thinking, and his math exercises were often changed, and his method of solving problems was very unique and original. On one occasion, the teacher of Jintan Middle School lamented that there were many "poor students" and no "talents" in the school. Wang Weike said, "Not necessarily. In my opinion, China is one! " "Hua Luogeng?" A teacher smiled and said, "Look at him, this word is like a crab crawling. Can he become a' talent'? " Wang Weike said with some excitement, "Of course, he has little hope of becoming a great calligrapher, but how can you see his talent in mathematics from between his lines?" You know, gold is buried in sand and looks no different from sand. What we need most as teachers' eyes is the ability to find gold in the sand, otherwise we will bury talents! "
When Hua started his career as a mathematician, he only had a missing page of Algebra and Calculus. Where there is a will, there is a way. He finally wrote that famous paper at the age of 19.
1in the spring of 930, his paper "Why can't the solution of Su Jiaju's algebraic quintic equation be established" was published in Shanghai Science Journal. Professor Xiong Qinglai, then head of the Department of Mathematics at Tsinghua University, attached great importance to this article. He asked the people around him, "Who is this Hua?" But no one has heard of Hua. Later, a teacher named Tang Peijing in Tsinghua introduced the life experience of his hometown Hua to Xiong Qinglai. "This young man is really not simple! He should be invited to Tsinghua. " Xiong Qing was very appreciative after listening to it. This year, Hua Cai 19 years old, but he has already gone through a rather bumpy life path.
Hua works and studies in Tsinghua University. It took him two years to complete the road that ordinary people need eight years to complete. 1933 was promoted to teaching assistant, 1935 became a lecturer. 1936 was recommended by Tsinghua University and sent to Cambridge University in England. During his two years in Cambridge, he devoted all his energy to the study of mathematical theoretical problems and was unwilling to waste time applying for a degree. His research results have attracted the attention of the international mathematics community. 1938 returned to China and was employed by Professor The National SouthWest Associated University. From 1939 to 194 1, under extremely difficult conditions, he wrote more than 20 papers and completed his first mathematical monograph, the theory of prime numbers on overlapping bases. Under the influence of Mr. Wen Yiduo, he also actively participated in the anti-Japanese democratic and patriotic movement that was in full swing at that time. The prime number theory based on piling later became a classic in mathematics. It was published in Russian in the Soviet Union on 1947, and was translated into German, English, Hungarian and Chinese for publication in various countries (China should have won the Stalin Prize for this book, but Stalin died).
1946 was invited to visit the Soviet union from February to May. 1946, the then national government also wanted to build an atomic bomb, so it sent three famous scientists, Hua, Zeng Zhaolun, to visit the United States. In September, Hua, Zhu Guangya and others left Shanghai for the United States. They first served as visiting professors at Princeton Institute for Advanced Studies, and later were hired as tenured professors by the University of Illinois.
Master of quick calculation-the harvest of history
Shi Fengshou, 1956, was born in Dali County, Shaanxi Province, China. 1980 graduated from the Department of Mathematics, China University of Science and Technology, and is currently the director of the International Research and Training Center for Fast Algorithm of Stone Harvest and the director of the Research Institute for Fast Algorithm of Stone Harvest. Professor Shi Fengshou, an international inventor of quick calculation, began to study speed algorithm at the age of1/kloc-0. After 10 years' efforts, he successfully broke the traditional calculation method of four operations for thousands of years, and created a fast calculation method that can count from the high position and immediately report the correct answer without using calculation tools and listing operation programs, thus causing a sensation at home and abroad and obtaining high evaluation. Professor Shi Fengshou has not only attracted the attention of international academic circles, but also been listed as a mathematical wizard in Chinese mainland. Now, he is actively engaged in promotion work. "International Research and Training Center for Fast Algorithm of Stone Harvest" and "Research Institute for Fast Algorithm of Stone Harvest" have been formally established in Shenzhen, and branches of training centers have been gradually set up around the world, hoping that this intellectual achievement invented by China people can contribute to all mankind.
19671/kloc-0 Xiao Fengshou took a photo with his mother. His mother believes in Christianity, is diligent and thrifty, and has a kind heart. She is very strict with her children's education, asking them to love the motherland and do good things for the people from an early age. In this year, 1 1 year-old Xiao Feng formally put forward the topic of fast algorithm. His mother's expectation always inspires him to set up the ideal of winning glory for his country, study hard and aspire to become a success. Because of the unprecedented "proletarian cultural revolution" at that time, the school was forced to suspend classes, so he couldn't go to school, so he buried himself in studying the speed algorithm at home and ran out of limited exercise papers. Because his family was poor and couldn't afford paper and pens, he practiced on the wall, insisted on practicing on the ground with wooden sticks, and even wrote numbers on the sheets, himself and the back of his hand, which was mistaken for "crazy" by others. Only the loving mother who knows him best understands that the child is exploring a fast algorithm. "Heaven rewards diligence" and "Hard work pays off". He finally successfully invented a fast algorithm in 1970. 1992, while Professor Shi was trying to spread the fast algorithm invented by himself to the whole world, he was shocked to learn that his hometown mother died of myocardial infarction, which was a heavy blow to his eldest son who worked thousands of miles away and loved his mother deeply. However, in order to serve the cultivation of the motherland and realize the entrustment of loving mother to do good for mankind, he turned grief into strength and devoted himself tirelessly to the promotion of historical harvest algorithm, determined to win glory for the Chinese nation.
The most famous story of stone harvest is the steamed bread of stone harvest. Stone Harvest is a famous fast calculator in China. When he was a child, he wrote and calculated, and he was often addicted to thinking.
One day at noon, he buried himself in calculation and didn't leave for dinner. Mother had to bring him two steamed buns to eat.
However, the small harvest has never been eaten. I soon forgot to eat and used steamed bread as manuscript paper.
The story of mathematicians-Sue
Su Yu 1902 was born in a mountain village in Pingyang County, Zhejiang Province in September. Although the family is poor, his parents scrimp and save, and they have to work hard to pay for his education. When he was in junior high school, he was not interested in mathematics. He thinks mathematics is too simple, and he will understand it as soon as he learns it. It can be measured that a later math class influenced his life.
That was when Su was in the third grade. He was studying in No.60 Middle School in Zhejiang Province. Teacher Yang teaches mathematics. He has just returned from studying in Tokyo. In the first class, Mr. Yang didn't talk about math, but told stories. He said: "In today's world, the law of the jungle, the world powers rely on their ships to build guns and gain benefits, and all want to eat and carve up China. The danger of China's national subjugation and extinction is imminent, so we must revitalize science, develop industry and save the nation. Every student here has a responsibility to' rise and fall in the world'. " He quoted and described the great role of mathematics in the development of modern science and technology. The last sentence of this class is: "In order to save the country and survive, we must revitalize science. Mathematics is the pioneer of science. In order to develop science, we must learn math well. "I don't know how many lessons Sue took in her life, but this lesson will never be forgotten.
Teacher Yang's class deeply touched him and injected new stimulants into his mind. Reading is not only to get rid of personal difficulties, but to save the suffering people in China; Reading is not only to find a way out for individuals, but to seek a new life for the Chinese nation. That night, Sue tossed and turned and stayed up all night. Under the influence of Teacher Yang, Su's interest shifted from literature to mathematics, and since then, she has set the motto "Never forget to save the country when reading, and never forget to save the country when reading". I am fascinated by mathematics. No matter it is the heat of winter or the snowy night in first frost, Sue only knows reading, thinking, solving problems and calculating, and has worked out tens of thousands of math exercises in four years. Now Wenzhou No.1 Middle School (that is, the provincial No.10 Middle School at that time) still treasures a Su's geometry exercise book, which is written with a brush and has fine workmanship. When I graduated from high school, my grades in all subjects were above 90.
/kloc-At the age of 0/7, Su went to Japan to study, and won the first place in Tokyo Technical School, where she studied eagerly. The belief of winning glory for our country drove Su to enter the field of mathematics research earlier. At the same time, he wrote more than 30 papers, and made great achievements in differential geometry. 193 1 obtained the doctor of science degree. Before receiving her doctorate, Su was a lecturer in the Department of Mathematics of Imperial University of Japan. Just as a Japanese university was preparing to hire him as an associate professor with a high salary, Su decided to return to China to teach with his ancestors. After the professor of Zhejiang University returned to Suzhou, his life was very hard. In the face of difficulties, Su's answer is, "Suffering is nothing, I am willing, because I have chosen the right road, which is a patriotic and bright road!" "
This is the patriotism of the older generation of mathematicians.
The epitaph of a mathematician
Some mathematicians devoted themselves to mathematics before their death, and after their death, they carved symbols representing their life achievements on tombstones.
Archimedes, an ancient Greek scholar, died at the hands of Roman enemy soldiers who attacked Sicily. ), people carved the figure of the ball in the cylinder on his tombstone to commemorate his discovery that the volume and surface area of the ball are two-thirds of that of the circumscribed cylinder. After discovering the regular practice of regular heptagon, German mathematician Gauss gave up the original intention of studying literature, devoted himself to mathematics, and even made many great contributions to mathematics. Even in his will, he suggested building a tombstone with a regular 17 prism as the base.
/kloc-Rudolph, a German mathematician in the 6th century, spent his whole life calculating pi to 35 decimal places, which was later called Rudolph number. After his death, someone else carved this number on his tombstone. Jacques Bernoulli, a Swiss mathematician, studied the spiral (known as the thread of life) before his death. After his death, a logarithmic spiral was carved on the tombstone, and the inscription also read: "Although I have changed, I am the same as before." This is a pun, which not only describes the spiral nature, but also symbolizes his love for mathematics.
