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."
/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.
