For an internationally famous China, a woman once went to buy cotton. Hua is solving a math problem. How much does the lady say it costs to pack cotton? However, diligent Hua didn't hear it, so she answered the calculated answer. The woman screamed, "Why is it so expensive?" At this time, Hua knew that someone was coming to buy cotton and said the price. The woman bought a bag of cotton and left. When Hua was about to sit down and continue to calculate, he found that the toilet paper that had just been calculated was taken away by the woman. This time, Hua was anxious to catch up desperately. A master Huang Bao met Professor Hua, a modern mathematician in China who enjoys a high reputation in the world.
I let him take the bus (because they knew each other) and finally caught up with him. Hua said shyly, "Aunt, please … please give me back the toilet paper." The woman said angrily, "I paid for it, but it wasn't from you." Hua was in a hurry and said, "How about this! I paid for it. " When Hua reached for the 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, he counted it again ... Hua published nearly 300 monographs and academic papers before his death, which solved some problems that could only be solved at the end of a long period in the history of mathematics in the world and made great contributions to the development of mathematics. In order to give full play to the role of mathematics in socialist construction, he personally went to more than 20 provinces and cities to popularize mathematical methods. 1979, China's famous mathematician Hua was invited to give a lecture in Britain. At a banquet, an American female scholar came to China to propose a toast. Suddenly, she raised her voice and asked, "Professor Hua, don't you regret going back to China?" "Original" here means 1950. That spring, Hua loved the news of the liberation of the mainland and resolutely gave up the favorable conditions of the United States and returned home with his family. On the way to Hong Kong, he sent an open letter to students studying in the United States, which wrote: "In order to choose the truth, we should go back, just for our personal way out, and we should also supplement it as soon as possible to establish the foundation of our work.
Strive for the construction and development of the motherland. In the face of this unfriendly question from the female scholar, Hua firmly and politely replied: "No! I have no regrets at all. I returned to China to do something for the motherland with my own strength, not for comfort, but for the motherland. " The forceful answer hit the patriotic feeling on the floor, which was beyond words and fully reflected his noble patriotic sentiment.
Chew while eating.
Hua, a famous mathematician in China, likes reading books in the library at school. But every time he goes, he always comes out after a while. The students are very strange and can't help talking. Some said, "He must not study hard." Someone said, "He must have skimmed the surface." ……
Students in order to find out this situation, one night, they quietly came to China's window and looked in through the window. I saw Hua read for a while, then turned off the light and went to bed. When they were ready to leave, the light in the room came on again-it turned out that Hua picked up the book again, read a few pages and smiled for a while.
When I was a child, I studied hard. However, Hua was called to see that shop (the one that sells cotton).
For an internationally famous China, a woman once went to buy cotton. Hua is solving a math problem. How much does the lady say it costs to pack cotton? However, diligent Hua didn't hear it, so she answered the calculated answer. The woman screamed, "Why is it so expensive?"

At this time, HuaCai slightly relieved, after returning home, he calculated again. ...
The next day, the students surrounded Hua and asked him to talk about the tricks of reading. Hua smiled and said to everyone, "I don't have any tricks either, but I think when reading, you should not only look with your eyes, but also feel with your heart." For some conclusions, remember them word by word first, as long as you understand them, it will be easy to remember. Therefore, when I read a book, I always read it without thinking. This is called' eating' and' chewing'. "
When Hua was a child, he liked thinking very much. After class, all his friends went out to play. He is still thinking about what the teacher said in the classroom. Sometimes he is so absorbed in thinking that his classmates tell him not to listen. Over time, his classmates gave him a nickname, calling him "Luo nerd".
The teacher opened Hua's math homework and found that many places had been altered and were not neat at all. The teacher was very dissatisfied at first. Later, he found that Hua was constantly improving and simplifying his solutions. After his talent in mathematics was discovered by the teacher, he devoted himself to cultivating him. After graduating from junior high school, Hua was admitted to Shanghai China Vocational School. After last semester, his family couldn't afford 50 yuan's room and board, so he had to drop out of school, so he only had a junior high school diploma for life. After coming home from school, he taught himself mathematics while helping his father manage the shop. When China comes to math problems, it seems that there is no one's business. He either forgot to receive the guests or drove them away. Either miscalculate the account and give more change. My father was very angry. Once, he burned Hua's math book, and Hua fainted in love.
That's it. Hua did not give up his research on mathematics, so he became a respected master of mathematics, and his life research was fruitful.
Some people may think that Hua must have been a top student in mathematics when he was a child, but in fact he was not witty when he was a child. Some people in villages and towns call him Dai. At the age of 6, he entered the primary school in this town, and at the age of 12, he entered the county junior high school. Before the second day of junior high school, mathematics (mathematics) academic performance was not excellent, but still "unqualified". After he became famous, someone asked about it, and he frankly criticized himself: "I was very playful when I was a child, and I often skipped school to watch social dramas."
Hua was shocked by his poor math performance, and he made up his mind to catch up. As a result, I read math textbooks to find math problems to do as soon as I have time, and gradually became interested in math.
One day, Li, a math teacher, showed everyone an interesting question after class. The topic is: "This matter is unknown, 3322, 55322, 7722. What is the geometry of things? " While other students were still thinking hard, Hua quickly raised his hand and replied, "23!" " Surprised, Teacher Li came over and asked, "You have seen the classic of Sun Tzu's calculation, which is China's' Remainder Theorem'. When it spread to the west, it was called' Sun Tzu Theorem'." . The teacher asked again, "You calculated it yourself, so tell me, how did you calculate it?" Hua slowly stated his thinking and calculation process: "I think so: this number is three plus three, and the number of seven plus seven is two." The answer to this question may be 3×7+2. I calculated again, 23 divided by 5, then 23 is the number I want! " The teacher excitedly told the students: "Hua's answer is correct, and the idea of calculus is completely correct." Since then, the whole class has looked at China with new eyes.
Hua's mathematical wisdom surprised the teacher. The teacher's encouragement greatly increased Hua's interest and made him redouble his efforts in mathematics. As a result, his math scores rushed up at once.
19101012. Hua was born in Jintan County, Jiangsu Province. He comes from a poor family and is determined to study hard. When I was in middle school, in a math class, the teacher gave the students a famous question: "There is a number, three places, and two;" 5 digits, 5 numbers, and the remaining 3; There are seven places in seven, and there are two left. What's the number of this? " While everyone was thinking, Hua stood up and said, "23". His answer surprised the teacher and won his praise. From then on, he fell in love with mathematics.
After finishing the first grade of junior high school, Hua dropped out of school because of his poor family, so he had to stand in front of the counter for his parents, but he still insisted on teaching himself mathematics. Through his unremitting efforts, his paper "Why can't the solution of Su Jiaju's algebraic quintic equation be established" was discovered by Professor Xiong Qinglai, head of the Department of Mathematics of Tsinghua University, and invited him to Tsinghua University; Hua was hired as a university teacher, which is unprecedented in the history of Tsinghua University.
1In the summer of 936, Hua, an outstanding mathematician, was a visiting scholar at Cambridge University in England for two years. At this time, the news of the Anti-Japanese War spread all over Britain, and he returned to the motherland with strong patriotic enthusiasm to give lectures for The National SouthWest Associated University.
China attaches great importance to the direct application of mathematical methods in industrial and agricultural production. He often goes deep into factory guidance, popularizes the application of mathematics and writes popular science books.
Hua has also set a shining example for young people to become self-taught. He is a self-taught mathematician without a college degree. He said: "I am not afraid of difficulties and study hard. This is my main experience in learning mathematics well." "The so-called genius is to rely on unremitting efforts.
Once, he went out to play with his neighbor's children, and they walked; Suddenly I saw an abandoned grave by the roadside, and there were many stone men and horses beside the grave. This immediately aroused Hua's curiosity, and he really wanted to find out. So he said to the neighbor's children:
"There may be some interesting things. Shall we go and see? "
The neighbor's child replied, "ok, but only for a while." I'm a little scared. "
Bold Hua said with a smile, "Don't be afraid, there are no ghosts in the world." With that, he ran to the grave first.
The two children studied the stone man and the horse carefully before they came to the grave. They groped around and found it interesting. Thinking Hua suddenly asked the neighbor's children, "How heavy are these stone men and horses?"
The neighbor's child looked at him puzzled and said, "How should I know? How can you ask such a stupid question? No wonder people call you' Luo Idiot'. "
Hua said disappointedly, "Can you think of a way to calculate?"
The children in the neighborhood laughed and said, "Wait till you become a mathematician in the future!" ! But if you can become a mathematician, I'm afraid you will work at sunrise and rest at sunset. "
Despite the ridicule of the children next door, Hua firmly said, "I will definitely find a way in the future."
Of course, calculating the weight of these stone men and horses is not a problem for Hua, who later became a mathematician.
There is a temple on Dongqinglongshan Mountain in Jintan County, and a temple fair is held every year. Young Hua is a person who likes to join in the fun, and he is indispensable in any lively place. One year, Hua also rushed to the temple fair with adults. A vivid scene attracted him. I saw a burly horse coming from Qinglong Mountain to the city, and immediately sat on a "Bodhisattva" covered with feathers and robes. Everywhere I went, people on the road bowed their heads and were very pious. After the worship, they put money in a small pot in front of the "Bodhisattva" so as to ask God for a sign, a doctor and a child.
Hua was amused, but he didn't kneel or worship the "Bodhisattva" himself. The adults standing by were very angry and scolded:
"Son, why don't you worship? This bodhisattva is amazing. "
"Is the Bodhisattva really that smart?" Hua asked.
One person said, "Of course, don't offend the immortals at a young age, or you will be in trouble."
"Is the Bodhisattva really omnipotent?" This question haunts China. He doesn't believe that a clay bodhisattva can really help the poor.
The temple fair broke up and all the spectators went home. However, Hua is far behind the "Bodhisattva". Seeing the "Bodhisattva" entering the Qinglong Mountain Temple, Xiaohua Luo Geng rushed over and looked out through the crack of the door. I saw the Bodhisattva move. He got off the horse, took off his flowered clothes, and conveniently wiped the makeup off his face. Hua Geng outside the door was shocked. It turned out that the "Bodhisattva" worshipped by the people was actually dressed up by a villager.
Hua finally solved the mystery in his heart. He told everyone in the village about cheating the Bodhisattva, and people finally realized. From then on, people looked at the child with new eyes, and no one called him "Luo nerd" anymore. It was Hua's spirit of asking what comes next that made him an outstanding mathematician.
