In the monotonous life of standing at the counter, he began to teach himself mathematics. /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! "

Mathematician Hua's short story 100 words.
When I was a child, Hua was born in a poor family and dropped out of junior high school without graduating. While helping my father look after the shop, he still doesn't forget to study. Without time, he got into the habit of getting up early, being good at using his spare time and mental arithmetic. Without books, paper and pens, he developed the habit of diligent hands-on and independent thinking.

Some mathematicians' stories are within 100 words (not more than), not Chinese.
The epitaph of mathematicians Some mathematicians devoted themselves to mathematics during their lifetime. After their death, their tombstones are engraved with symbols representing their achievements in life. 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 depicts the spiral nature, but also symbolizes his love for mathematics. There are many interesting stories in the story of mathematician Gauss when he was a child. The first-hand information of the story often comes from Gauss himself, because he always likes to tell what happened after his childhood in his later years. We may doubt the truth of this story, but many people have confirmed what he said. Gauss's father works as a foreman in a tile factory. He always pays his workers every Saturday. When Gauss was three years old in the summer, when he was about to get paid, Little Gauss stood up and said, "Dad, you are mistaken." Then he said another number. It turned out that three-year-old Gauss was lying on the floor, secretly following his father to calculate who to pay. The results of recalculation proved that little Gauss was right, which made the adults standing there dumbfounded. Gauss often joked that he had learned to calculate before he learned to speak, and often said that he learned to read by himself only after consulting adults about the pronunciation of letters. At the age of seven, Goss entered St. Catherine's Primary School. When I was about ten years old, my teacher had a difficult problem in arithmetic class: "Write down the integers from 1 to 100 and add them up! Whenever there is an exam, they have this habit: the first person who finishes it puts the slate face down on the teacher's desk, and the second person puts the slate on the first slate, thus falling one by one. Of course, this question is not difficult for people who have studied arithmetic progression, but these children are just beginning to learn arithmetic! The teacher thinks he can have a rest. But he was wrong, because in less than a few seconds, Gauss had put the slate on the lecture table and said, "Here's the answer! Other students added up the numbers one by one, sweating on their foreheads, but Gauss sat quietly, ignoring the contemptuous and suspicious eyes cast by the teacher. After the exam, the teacher checked the slate one by one. Most of them were wrong, so the students were whipped. Finally, Gauss's slate was turned over and there was only one number on it: 5050 (needless to say, this is the correct answer. The teacher was taken aback, and Gauss explained how he found the answer:1+100 =1,2+99 =10/,3+98 =/kloc-. A * * * has 50 pairs, and the sum is 10 1, so the answer is 50 × 10 1 = 5050. It can be seen that Gauss found the symmetry of arithmetic progression, and then put the numbers together in pairs, just like the general arithmetic progression summation process. The story of the mathematician Gauss 1777~ 1855 was born in Brunswick, located in the north-central part of Germany. His grandfather is a farmer, his father is a mason, his mother is a mason's daughter, and he has a very clever brother, Uncle Gauss. He takes good care of Gauss and occasionally gives him some guidance, while his father can be said to be a "lout" who thinks that only strength can make money, and learning this kind of work is useless to the poor. Gauss showed great talent very early, and at the age of three, he could point out the mistakes in his father's book. At the age of seven, I entered a primary school and took classes in a dilapidated classroom. Teachers are not good to students and often think that teaching in the backcountry is a talent. When Gauss was ten years old, his teacher took the famous "from one to one hundred" exam and finally discovered Gauss's talent. Knowing that his ability was not enough to teach Gauss, he bought a deep math book from Hamburg and showed it to Gauss. At the same time, Gauss is familiar with bartels, a teaching assistant who is almost ten years older than him. bartels's ability is much higher than that of the teacher. Later, he became a university professor, giving Professor Gauss more and deeper mathematics. Teachers and teaching assistants went to visit Gauss's father and asked him to let Gauss receive higher education. But Gauss's father thought that his son should be a plasterer like him, and there was no money for Gauss to continue his studies. The final conclusion is-find a rich and powerful person to be his backer, although I don't know where to find it. After this visit, Gauss got rid of weaving every night and discussed mathematics with Bater every day, but soon there was nothing to teach Gauss in Bater. 1788, Gauss entered higher education institutions despite his father's opposition. After reading Gauss's homework, the math teacher told him not to take any more math classes, and his Latin soon surpassed the whole class. Mathematician Hua's childhood anecdote (1910-1982) was born in Jintan County, Taihu Lake, Jiangsu Province, and was named because his father Hua's hometown put it in the laundry list for good luck when he was born. Hua loved to play and join in the fun since he was a child, but his lessons were mediocre and sometimes he failed. I barely finished primary school and entered Jintan Middle School in my hometown, but I was still playful and my handwriting was crooked. When I do my math homework, I draw it carefully, but it's like graffiti. Therefore, Hua in junior high school is still disliked by teachers and often ruled. Wang Weike, a middle school teacher in Jintan, has a unique vision. He studied Hua's graffiti book and found that these altered places reflected various methods he explored when solving problems. On one occasion, Teacher Wang Weike told his students that Sun Tzu's Calculation of the Art of War had such a problem: "This matter is unknown, and the number of three and three is the second, the number of five and five is the third, and the number of seven and seven is the second. What is the geometry of things? " When everyone was silent, a student stood up. As you can see, flowers have always been looked down upon. At that time, he was only fourteen. Can you guess how much Hua said? Chen Jingrun: When I was a child, my professor gave me a pearl. More than 20 years ago, a reportage "Goldbach Conjecture", which caused a sensation in China, made a mathematical wizard a household name overnight. The deeds of this man even promoted the early arrival of a great era of respecting science, knowledge and talents to a certain extent. His name is Chen Jingrun. Not talkative, he used to be an "ugly duckling". Usually, a person who is born deaf will have a particularly keen eye, a person who is born blind will have a very keen hearing, and an "ugly duckling" who has been neglected and unpopular since childhood will often meditate involuntarily or in all kinds of helplessness, explore things, learn from things, and find a suitable position in the world to develop his potential. You can say that this is forced out, but such "forced" will often "force" many great people. Like Chen Jingrun in childhood. Chen Jingrun was born in 1933, the family of a post office clerk. He just turned 4 when War of Resistance against Japanese Aggression started. Soon, the wolf smoke of the Japanese invaders burned to his hometown of Fujian, and the whole family fled into the mountains, and the children entered the mountain school. Fathers are too busy making a living to take care of their children's education; My mother is an old housewife and has worked hard all her life. She had 65,438+02 children, but only six survived. Chen Jingrun is the third, with brothers and sisters, and younger brothers and sisters. There is an old saying in China that "the little boy in the middle has a flat head". He is thin and weak. It is conceivable that he is dissatisfied with his parents and is not good for his brothers and sisters. At school, he is no better, because he is silent and doesn't like to talk. Unpopular, bullied, and often beaten and scolded for no reason. It happened that he was stubborn by nature and never begged for forgiveness in order to improve his situation. Unconsciously, he formed a self-enclosed introverted personality. People always need to communicate, especially children. A gifted child, faced with this dilemma, may become a perverse Woodenhead, but Chen Jingrun didn't. His natural passion for numbers and symbols made him forget the hardships and troubles of life and concentrate on the pagoda of knowledge. He wants to find a breakthrough and find happiness in life there. Teaching students in accordance with their aptitude is to create a space for each student to fully develop according to their own characteristics through certain educational and teaching methods and means. Chen Jingrun Jr. teaches students in accordance with their aptitude. Fortunately, this pupil has met a professor all his life, but he is still a child. In addition to burying your head in reading, you need face-to-face and hands-on guidance. After all, what can bring the greatest, most direct and vivid inspiration and joy to children is the kind of communication and contact between people, which can make people's hearts glow with brilliant sparks. Fortunately, when the family returned to Fuzhou, Chen Jingrun met Shen Yuan, a famous teacher who claimed to be a lifelong beneficiary. Shen Yuan is a famous aerodynamicist, an aviation engineering educator and a leading figure in China's aviation industry. He graduated from the University of London, Imperial College London, and was the head of the aviation department in Tsinghua University. He went back to Fuzhou from 1948 to take care of his family. During the war, he had to stay in his alma mater Huaying Middle School to teach temporarily, and Chen Jingrun was the student in his class. Professors in famous universities have their own unique skills in teaching young children. According to the age and psychological characteristics of the teaching object, Shen Yuan often introduces the explanation of the topic in a simple way by telling stories, which can easily lure those young children into the superb scientific world and arouse their great enthusiasm for science and learning. For example, on this day, Professor Shen Yuan told the students a story about Goldbach's conjecture with great interest. We all know that in positive integers, 2, 4, 6, 8, 10 ... is an even number that can be divisible by 2; 1, 3,5,7,9, etc. It is called odd number. There is also a number that can only be divisible by 1 and itself, but not by other integers. This number is called prime number. "As usual, in the whole classroom, even the sound of an embroidery needle falling to the ground can be heard silently, and only Professor Shen's calm and rich voice echoes." More than 200 years ago, a German middle school teacher named Goldbach discovered that every even number not less than 6 is the sum of two prime numbers. For example, 6 = 3+3, 12 = 5+7,18 = 7+1,24 = 1 1+ 13 ... "However, guess is guess after all. Without rigorous scientific argumentation, it can only be a guess forever. " Now it's Chen Jingrun Jr.' s turn to make a commotion. But in my heart. How to scientifically demonstrate? Can I grow up? He thought. Later, Goldbach wrote a letter to the famous mathematician Euler at that time. Euler received this letter with great enthusiasm and threw himself into this interesting debate almost immediately. Unfortunately, however, despite Euler's painstaking efforts, he failed to prove this conjecture until his death. Since then, Goldbach conjecture has become a world-famous mathematical problem. For more than 200 years, it has made many talented scholars and heroes of mathematics advance wave after wave and compete with each other. The classroom is boiling, and the children's curiosity and imagination are mobilized. "Mathematics is the queen of natural science, and the crown on the queen's head is number theory. The Goldbach conjecture I just mentioned is a dazzling pearl in the queen's crown! " Shen Yuan finished the story about Goldbach's conjecture in one go. The students talked about it in succession, and it was very lively, but the introverted Chen Jingrun didn't say a word, and the whole person was "crazy". This quiet, quiet and thoughtful child was completely brought into a colorful magical world by Shen Yuan's story. When other students were amazed at him, the admiration ended as soon as it passed, but he secretly said to himself over and over again, "Can you do it? Can you take off this jewel in the crown of mathematics? " One is a university professor and the other is a child with yellow mouth. Although there is no communication or even conversation between them in the strict sense, this class is really a heart-to-heart meeting, because it laid the foundation for Chen Jingrun Jr.' s beautiful ideal, a goal to work hard for, and made him willing to fight for it all his life! Many years later, Chen Jingrun graduated from Xiamen University. A few years later, he was appreciated by the famous mathematician Hua and transferred to the Institute of Mathematics of China Academy of Sciences. Since then, under the leadership of China, Chen Jingrun devoted himself to the long-term and outstanding demonstration of Goldbach's conjecture day and night. 1966, a dazzling new star rose in the field of mathematics in China. Chen Jingrun told the world in the China Science Bulletin that he proved it (1+2)! 1In February, 973, Chen Jingrun, who rose from the catastrophe of the Cultural Revolution, revised (1+2) the certificate again. A theorem it proved shocked the international mathematics community and was named "Chen Theorem". I don't know if Professor Shen Yuan can still remember what he said to these children in those years, but Chen Jingrun always remembers that he has been so clear all his life. Chen Jingrun (1933- 1996), a famous mathematician, was a celebrity since he was a child. 1950 was admitted to the sophomore year of Xiamen university, and 1953 graduated to teach there. 65438-0957, transferred to Institute of Mathematics, Chinese Academy of Sciences, and later became a researcher. 1973 published the paper "The big even table is the product of a prime number and the product of no more than two prime numbers". 1979 "The Minimum Prime Number in arithmetic progression" was published. 1980 was elected academician of China Academy of Sciences (academician of China Academy of Sciences).

Mathematicians' stories are about 100 words (9 stories).
I once did a math problem when I was looking at the shop. A lady came and wanted to buy cotton. When she asked Hua how much it was, he was absorbed in the problem and didn't hear what the other party said. After calculating the answer, he casually said a number. The lady thought he was talking about the price of cotton and screamed, "Why is it so expensive?" . At this time, Hua knew that someone had come to buy cotton. When Hua sold cotton to a lady, he found that the toilet paper he used to calculate the problem was taken away by a lady. This made Hua desperate to catch up with the young lady, and he finally caught up with her. Hua said shyly, "aunt, please ... please give me back the toilet paper." The woman said angrily, "this is the money I paid, but ... Hua was in a hurry and said," How about this! I paid for it. When Hua reached out for money, the woman seemed to be moved by the child. "！ He not only asked for money, but also returned the toilet paper to Hua. At this time, HuaCai slightly relieved. After returning home, I began to calculate math problems again. 2. Gauss Gauss's most famous story is to calculate the value of 1+2+3+ ... elementary school+100. At that time, Gauss was in primary school, and the teacher had such a problem in class, so let everyone calculate. The teacher thought it would take at least 20 minutes to get the answer, and just wanted to have a rest, but Gauss said that his ass had been worked out before he could sit still. The teacher was surprised and asked him how to calculate. He said that we should start with1+100 =101,and 2+99= 10 1. . . Such a * * * has 50 10 1, so the result is 5050. There is another story. When Gauss 19 years old, he originally planned to study law. As a result, he inadvertently solved a math problem in 2000, that is, he only used a ruler and compasses to divide the circumference equally. Gauss also proved that if and only if n = 2 (2 n)+ 1, the circumference can be equally divided by a ruler n. Since then, Gauss's interest in mathematics has greatly increased, and he has embarked on the road of mathematical research and become a great mathematician. 3. Euler 1707 was born in Basel, Switzerland. When he was a child, he liked mathematics very much. He began to teach himself algebra when he was below 10. Even several of his teachers haven't read the book, but little Euler read it with relish. When he meets something he doesn't understand, he marks it with a pen and then asks others for advice afterwards. /kloc-When he was 0/3 years old, he went to university of basel to study, which was a miracle at that time and once caused a sensation in mathematics. Little Euler is the youngest student in this university and even in the whole Swiss university campus. In college, I got the careful guidance of johann bernoulli (1667- 1748), the most famous mathematician in calculus at that time, and gradually established a deep friendship with him. Johann bernoulli later praised shine on you as better than the students in Lanzhou: "When I introduced Advanced Analysis, he was still a child, and you brought him up. "Two years later in the summer, Euler got a bachelor's degree in university of basel, and the following year, Euler got a master's degree in philosophy in university of basel. 1725, Euler began his mathematics career. 4. Chen Jingrun, Chen Jingrun doesn't like walking in the park or going shopping, but he likes studying. When I study, I often forget to eat and sleep. One day, Chen Jingrun touched his head during lunch. Alas, his hair is too long. He should get a haircut at once, or others will think he is a girl. So he left work and ran to the barber shop. There are so many people in the barber shop that everyone cuts their hair next to each other. Chen Jingrun's brand is the small brand number 38. He thought it was too early for me to turn now. Time is so precious that I can't waste it. He hurried out of the barber shop, found a quiet place to sit down, then took out a small notebook from his pocket and recited new words in a foreign language. 5. Newton "I must surpass him! "When it comes to Newton, people may think that he must have been a child prodigy and a genius with extraordinary intelligence. In fact, Newton's childhood was thin and his mind was not smart. When I was studying in my hometown, I didn't study hard and got poor grades in my class. But he has a wide range of interests and his game skills are higher than those of ordinary children. Usually he likes to make mechanical models, such as windmills, waterwheels, sundials and so on. His elaborate water clock has won people's praise for its accurate timing. Sometimes, the way he plays ball is also very strange. One day, he made a lantern and hung it on the tail of a kite. When night falls, the lighted lanterns rise into the air with the help of the rising power of kites. Luminous lanterns flow in the air, and people are frightened and think there is a comet. Nevertheless, he is often discriminated against because of his poor academic performance. At that time, the hierarchy of British feudal society was very serious. Students who study well in primary and secondary schools may discriminate against those who study poorly. There was a game between classes. When everyone was in high spirits, a good student kicked Newton and called him an idiot. Newton's mind was stimulated to extreme anger. He thought, we are all students. Why should I be bullied by him? I must pass him! From then on, Newton made up his mind to study hard. He gets up early and goes to bed late. Every minute counts. He studies hard and thinks hard. After studying hard, Newton's academic performance improved continuously, and soon surpassed the classmate who had bullied him, ranking first in the class.

The story of mathematician Hua is about 150 words.
1. 1953, the Academy of Sciences organized a delegation to go abroad, headed by the famous scientist Qian Sanqiang. Members include Hua, Zhao Jiuzhang and Zhu Xian. In his spare time, Hua wrote a couplet: "The top three are Korea, Zhao and Wei", seeking this couplet. The "top three" here refers to Korea, Zhao and Wei San during the Warring States Period, but it implies the name of the head of the delegation, Comrade Qian Sanqiang, which not only solves the traditional difficulty of the couplet of numbers and numbers, but also requires the name of another scientist to be embedded in the bottom couplet. After a while, when Hua saw that everyone had no bottom line, he revealed his bottom line: "Hook, strand and string are nine chapters." Nine Chapters is a famous mathematical work in ancient China. However, the "Nine Chapters" here happen to be the name of another member of the delegation-atmospheric physicist Zhao Jiuzhang. Hua's wonderful pair made the audience fall for it. 1980, when Professor Hua was guiding the overall planning method and optimization method in Suzhou, he wrote the following couplets: Watching chess is not a gentleman, helping each other in the same boat; Be a person with regrets and correct your mistakes. 2. While continuing to study mathematical theory, China strives to find a way to combine mathematics with industrial and agricultural practice. After a period of practice, he found that the overall planning method and optimization method in mathematics can be widely used in industrial and agricultural production, which can improve work efficiency and change the face of work management. Therefore, while giving lectures at the University of Science and Technology, he led students to promote the optimization method and overall planning method in industrial and agricultural practice. At the beginning of 1964, he wrote to Mao Zedong, expressing his determination to take the road of combining workers and peasants. On March 18 of the same year, Mao Zedong wrote back: "I have read both poems and letters. Top gun, congratulations. " He wrote "Brief Introduction and Supplement to the Master Planning Law" and "Brief Introduction and Supplement to the Optimal Selection Law", and personally led the teachers and students of China University of Science and Technology to some enterprises and factories to promote and apply the "double methods" to serve industrial and agricultural production. "Go to Jianghan to fight the heat in summer and go to Songliao first frost in winter." This is a portrayal of his life at that time. In 1965, Mao Zedong wrote to him again, congratulating and encouraging him to "work hard and serve the people, not the individual". Hua's early research field was analytic number theory, and his achievements in analytic number theory were particularly famous. The internationally famous "China Analytic Number Theory School" is a school initiated by China, which has made many significant contributions to the distribution of prime numbers and Goldbach conjecture. Hua is also the founder and pioneer in the research of analytic number theory, matrix geometry, canonical group and automorphism function theory in China. China's research on the theory of multiple complex variables and canonical group theory is ahead of the western mathematics field 10 years, and it is an internationally famous "canonical group China school". Establish China School of Mathematics and lead it to the world-class level. Many outstanding young people have been trained, such as Wang Yuan, Chen Jingrun, Wan Zhexian, Lu Qikeng and Gong Sheng. The story of Baidu Encyclopedia, a story is about 100 words, not too long.
Buffon: One day, French mathematician Buffon invited many friends to his home and did an experiment. Buffon spread a big piece of white paper on the table, which was covered with parallel lines with equal distance. He also took out many small needles of equal length, the length of which was half that of parallel lines. Buffon said, "Please feel free to put these small needles on this piece of white paper!" " The guests did as he said. Buffon's statistics show that everyone * * * throws 22 12 times, in which the small needle intersects the parallel line on the paper 704 times, and 2210 ≈ 704 ≈ 3.142. Buffon said, "This number is an approximation of π. Every time you get an approximation of pi, the more times you throw it, the more accurate the approximation of pi is. " This is the famous Buffon Experiment.
