The story of mathematician Hua:/kloc-0 One day in 930, Xiong Qinglai, head of the Department of Mathematics at Tsinghua University, was sitting in his office reading Science magazine. Looking at it, I can't help but exclaim: "Which country is this China from?" Everyone around shook their heads. "Which university does he teach at?" People looked at each other. Finally, a Jiangsu-born teacher thought for a long time before slowly saying, "My brother has a classmate named Hua. Which university did he teach at? " ! He only went to junior high school and heard that he worked as a clerk in Jintan Middle School. "
Xiong qinglai was surprised. A person who graduated from junior high school must be a genius to write such a profound mathematical paper. He immediately decided to invite Hua to Tsinghua University.
Since then, Hua has become a teaching assistant in the Department of Mathematics of Tsinghua University. Here, he is like a duck to water, swimming in the ocean of mathematics every day, leaving only five or six hours of sleep for himself. It's hard to believe that flowers have developed the habit of reading books after turning off the lights. Of course, he has no special function, just a logical thinking activity in his mind. He took a book and put it under the lamp, looked at the topic and thought for a while, then turned off the lamp and lay in bed, closed his eyes and meditated, and began to do the problems in his mind. Turn over and get out of bed when you encounter difficulties, and open your books for a while. In this way, a book that took ten days and a half months to finish, he finished it in one night and two nights. Hua is regarded as a rare assistant.
The following year, his papers began to be published in famous foreign mathematical magazines. Tsinghua University broke the precedent and decided to promote Huawei teaching assistants with only junior high school education.
A few years later, Hua was sent to Cambridge University in England to study. However, he doesn't want to study for a doctorate, but only wants to be a visiting scholar. Because being a visiting scholar can break through the shackles and learn seven or eight subjects at the same time. He said, "I came to study in England, not to get a degree."
Hua didn't get a doctorate. During his two years in Cambridge, he wrote 20 papers. On the level, every article can get a doctorate. In one of the studies on "the problem in the tower", his theory was named "Fahrenheit theorem" by the mathematical community.
Hua devoted himself to his favorite mathematical research with the spirit of loving science, being diligent in research and not seeking fame and fortune. He abandoned the money, fame and position that the world sought. In the end, his career succeeded.
China closely combines scientific research with practical application. Hua applied mathematics to industrial and agricultural production and made outstanding contributions to China's modernization.
/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.
1966 In May, a dazzling new star flashed over the global mathematics world-Chen Jingrun announced that he had proved "1+2" in Goldbach's conjecture; 1972 February, completed the modification of "1+2" certificate. Incredibly, foreign mathematicians use large high-speed computers to prove "1+3", while Chen Jingrun relies entirely on paper, pens and skulls. If this is puzzling, then the six sacks of manuscript paper he used to simplify the proof of "1+2" is enough to show that Chen Jingrun has become an internationally renowned mathematician and is deeply respected by people. However, instead of being complacent, he attributed all the credit to the motherland and the people. In order to safeguard the interests of the motherland, he did not hesitate to sacrifice his personal fame and fortune.
1977 One day, Chen Jingrun received a letter from the president of the International Federation of Mathematicians, inviting him to attend the International Congress of Mathematicians. There are 3000 people present at this meeting, all of whom are world-famous mathematicians. Chen Jingrun is one of 10 mathematicians designated by the congress to give academic reports. This is a great honor for a mathematician. Zhang, male, 1948, from Shaanxi. Shortly after his birth, he went to live in Taiwan Province Province with his parents. She was smart since childhood, loved reading and had a soft spot for mathematics. After graduating from high school, Zhang was admitted to the Department of Mathematics of a famous university in Taiwan Province Province, and obtained a bachelor's degree of 1970. She was not satisfied with this. She was admitted to the University of California with excellent results and studied for a doctorate in mathematics. Reputation is of great benefit to enhancing Chen Jingrun's international reputation.
The story of Euler
At that time, little Euler was studying in a missionary school. Once, he asked the teacher how many stars there were in the sky. The teacher is a believer in theology. He doesn't know how many stars there are in the sky, and the Bible doesn't answer. In fact, there are countless stars in the sky, which are infinite. There are thousands of stars visible to the naked eye. Without pretending to understand, the teacher replied to Euler, "It doesn't matter how many stars there are in the sky, as long as you know that the stars in the sky are inlaid by God." Euler felt very strange: "The sky is so big and so high, and there is no escalator on the ground. How did God embed the stars on the screen one by one? " God himself put them in the sky one by one. Why did he forget the number of stars? Could God be too careless? He asked the teacher a question in his heart, and the teacher was confused again, blushed and didn't know how to answer. A sudden anger rose in the teacher's heart, not only because a child who just went to school asked the teacher such a question, so that the teacher could not step down, but more importantly, the teacher regarded God above everything else. Little Euler blames God for not remembering the number of stars. The implication is that he doubts almighty god. In the teacher's view, this is a serious problem. In Euler's time, there was absolutely no doubt about God. People can only be slaves of ideas, and they are absolutely not allowed to think freely. Little Euler didn't "keep in line" with the church and God, so the teacher told him to leave school and go home. However, in little Euler's mind, the sacred aura of God disappeared. God is a loser, he thought. Why can't he even remember the stars in the sky? He thought, God is a dictator, and even asking questions has become a crime. He thinks that God may be a guy made up by others and does not exist at all. After returning home, he helped his father herd sheep and became a shepherd boy. Dad's flock increased gradually, reaching 100. The original sheepfold was a little small, so my father decided to build a new sheepfold. He measured a rectangular piece of land with a ruler, 40 meters long and 15 meters wide. He calculated that the area is exactly 600 square meters, with an average of 6 square meters per sheep. When he was ready to start construction, he found that his materials were only enough for the fence of 100 meters, which was not enough at all. If you want to enclose a sheepfold with a length of 40m and a width of 15m, its circumference is110m (15+15+40+40 =1/kloc-0). If we want to build it according to the original plan, my father feels very embarrassed. If the area is reduced, the area of each sheep is less than 6 square meters. Little Euler told his father that there was no need to shrink the sheepfold and not to worry that the territory of each sheep would be smaller than originally planned. He has an idea. Father didn't believe that little Euler would have a way, so he ignored him. Little Euler was in a hurry and said loudly, only moving a little stake in the sheepfold. Father shook his head and thought, "How can there be such a cheap thing in the world?" However, little Euler insisted that he would be able to kill two birds with one stone. The father finally agreed to let his son try. Little Euler saw his father agree, stood up and ran to the sheepfold to get ready to start work. He shortened the original side length of 40 meters to 25 meters centered on the stake. The father was anxious and said, "How can that be done? Then how to do it? This sheepfold is too small, too small. " Little Euler didn't answer, so he ran to the other side and extended the original side length of15m, and increased it by10m to 25m. In this way, the original planned sheepfold has become a square with a side length of 25 meters. Then, little Euler confidently said to his father, "Now, the fence is enough and the area is enough." My father built a fence according to the sheepfold designed by little Euler. 100 meter long fence is really enough, no more, no less, all used up. The area is enough, a little bigger. Father felt very happy. Children are smarter than themselves, they really use their brains, and they will definitely have a bright future. Father thinks it's a pity to let such a clever child herd sheep. Later, he tried to let little Euler know the great mathematician Bernoulli. On the recommendation of mathematicians, little Euler became a college student in university of basel on 1720. This year, little Euler 13 was the youngest student in this university.
Landlord, I only have one article, more than twenty. However, twenty crosses are rare! The fine print you just typed has exceeded twenty crosses! ! !

About 1500 years ago, European mathematicians did not know how to use "0". They use Roman numerals. Roman numerals are symbols representing numbers, which are combined to represent different numbers according to certain rules. When using this number, the number "0" is not needed.
At that time, a scholar of the Roman Empire discovered the symbol "0" from Indian notation. He found it very convenient to use "0" for mathematical operation, and he was very happy. He also introduced the Indian method of "0" to everyone. After a while, it was known by the pope at that time. At that time, it was the Middle Ages in Europe. The power of the church was very strong, and the power of the pope far exceeded that of the emperor. The Pope was very angry. He rebuked that the sacred number was created by God, and there was no such monster as "0" in the number created by God. Anyone who wants to introduce now is blasphemous! So the Pope ordered the scholar to be arrested and tortured, and his ten fingers were tightly clamped with a clamp, so that his hand was disabled and he could no longer write with a pen. In this way, "0" was banned by the ignorant and cruel Pope.
However, although the use of "0" is forbidden, Roman mathematicians still use "0" secretly in mathematical research regardless of the ban, and still make a lot of mathematical contributions with "0". Later, "0" was finally widely used in Europe, but Roman numerals were gradually eliminated.
Children, do you know the story of Gauss, a mathematical genius, when he was a child?
When Gauss was in elementary school, once after the teacher taught addition, because the teacher wanted to have a rest, he came up with a topic for students to calculate. The theme is:
1+2+3+ .....+97+98+99+ 100 = ?
The teacher is thinking, now the children must start class! I used this as an excuse to go out, but Gauss stopped me! ! It turns out that Gauss has worked it out. Little friend, do you know how he did it?
Gauss told everyone how he worked it out: add 1 to 100, and add 100 to 1, adding two lines, that is:
1+2+3+4+ .....+96+97+98+99+ 100
100+99+98+97+96+ .....+4+3+2+ 1
= 10 1+ 10 1+ 10 1+ .....+ 10 1+ 10 1+ 10 1+ 10 1
* * * There are one hundred sums 10 1, but the formula is repeated twice, so the answer is equal to < 5050 & gt.
Since then, the learning process of Gauss Elementary School has already surpassed other students, which laid the foundation for his future mathematics and made him a mathematical genius!
In daily life, mathematics is everywhere, such as: buying and selling vegetables, calculating how much …
Flower's juvenile story
Hua is a first-rate mathematician in the world. He has made brilliant achievements in many fields of mathematics. However, when he was young, he was an unpleasant child.
When Hua went to school, his teachers and classmates found that he was not good at words, his grades were not good, he was always clumsy and taciturn, and his classmates nicknamed him "Luo Daku". Moreover, behind the scenes, it is often said: "Luo Idiot of Hua's hometown will not have any future when he grows up."
In fact, Hua is a very clever boy. He likes to use his head very much, but he doesn't like to talk at ordinary times and is all thumbs, so others always don't notice him.
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, 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 doubtfully and said, "How do we 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, "There will be 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 getting to the bottom of the matter that made him an outstanding mathematician. Add comments
