Hua (19 10~ 1985), mathematician, academician of China Academy of Sciences. 191010 65438 was born in Jintan, Jiangsu province, and 1985 12 died in Tokyo, Japan. Hua used to be a naughty boy, but he was very talented in mathematics. Once, the math teacher worked out a famous math problem in ancient China-there was one thing, I don't know how many. Three places and three places, with a surplus of 2; 5 digits, 5 numbers, and the remaining 3; Seven numbers of seven, leaving two. How much is this thing? After the topic came out, the students talked about it, and no one could tell. The teacher was about to speak when Hua raised his hand and said, "I have worked it out." It is 23. " Not only did he get the numbers right, but the algorithm was also very special. This surprised the teacher greatly. However, the clever boy dropped out of school after finishing middle school because his family was poor. He returned home and did business in his small grocery store, selling cigarettes, needle and thread, etc., and shouldered the burden of bringing home the bacon for his father. However, Hua still loves mathematics. If you can't go to school, try to learn by yourself. On one occasion, he borrowed some math books from his teacher, and became fascinated when he saw them. From then on, he studied mathematics while doing business and accounting. Sometimes he is so absorbed in reading that he forgets to say hello when people buy things. In the evening, after the shop closed, he wandered around the kingdom of mathematics wholeheartedly. For a whole year, I spent more than ten hours studying the borrowed math books almost every day. Sometimes when I sleep until midnight and think of a solution to a difficult math problem, he will definitely turn over, light a small oil lamp and write down the solution. At this time, he got typhoid fever. He stayed in bed for half a year and finally recovered his life, but his left foot was disabled for life. In the case of poverty and illness, Hua still devoted all his energy to mathematical research, and published several important papers in succession, which attracted the attention of Professor Xiong Qinglai of Tsinghua University. Hua studied hard when he was a child, but Hua was told to look at the shop (the shop selling cotton). Once, a woman 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. China is anxious to catch up desperately. A yellow bag master asked him to drive after him 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 calculated again ... Gauss was an outstanding mathematician, physicist and astronomer in Germany in the19th century. Some people say that Gauss is an extremely clever genius, but Gauss said, "My knowledge and success are all obtained by diligent study. When I was a child, I liked math very much. I learned to count even before I learned to speak! One day, Gauss's father was settling the wages of several workers, and he was so tired that he was sweating all over. " Hey, I finally figured it out! "Father stood up, stretched himself and said." Dad, you are not right! "The little Gauss standing on the side whispered," It should be ... ""How do you know? "Father asked disapprovingly." I figured it out in my heart! "Gauss innocently said," don't believe me. "My father calculated it again carefully and found that the calculation was really wrong. The sum of what my son said was right. Surprised and delighted, he said excitedly, "smart boy, dad will send you to school in a few days." "Gauss entered a rural primary school at the age of eight. The teacher who teaches mathematics is from the city. He thinks it is really overqualified to teach several children to read in the backcountry. However, he is somewhat biased: he thinks that poor children are born idiots and there is no need to teach these stupid children to study hard. If there is an opportunity, they should be punished to add some fun to this boring life. This day is a very unhappy day for the math teacher. The students were scared when they saw the teacher's gloomy face, knowing that the teacher would punish the students again today. " You calculate a problem today, from 1 plus 2 plus 3 to 100. Whoever can't figure it out will be punished for not going home for dinner. After the teacher only said such a sentence, he picked up a novel and sat in the chair without saying a word. So, the children in the classroom picked up the slate and began to calculate: "1 plus 2 equals 3, 3 plus 3 equals 6, 6 plus 4 equals10 ..." Some children added the result to a number and erased it on the slate, and the number became larger and larger, making it difficult to calculate. Some children's little faces turned red, and some children's palms and foreheads oozed sweat. Less than half an hour later, Little Gauss picked up his slate and stepped forward: "Teacher, is this the answer?" Without looking up, the teacher waved his thick hand and said, "Go, go back!"! Wrong. " He thought, children can't work out the answer so quickly. But Gauss stood still and put the slate in front of the teacher: "Teacher! I think this answer is correct. " The math teacher wanted to shout, but she saw the number written neatly on the slate, which was 5050. He was surprised because he calculated it himself and got the number 5050. How did this 8-year-old figure out so quickly? Gauss explained to the teacher, "If you add the numbers from 1 to 100,100 =10/kloc-0, 2+99 =1065433. The sum of every two numbers is 10 1. 100, and there will be 50 results, and each result is 10 1, so 501add up to 5050. Gauss's discovery made the teacher feel very ashamed, and he began to realize that it was wrong for him to be arrogant and look down on children from poor families. Since then, teachers have changed their views on rural students. He likes Gauss very much and often buys some new books for Gauss to read. With the enthusiastic help and guidance of the teacher, Gauss became more and more interested in mathematics, and he had an indissoluble bond with mathematics all his life.
