Poor family, but don't forget your innovative spirit.
And the hero we are going to talk about today is such a person. He is Yu Jianchun from Dabie Mountain in Xinyang, Henan. His family is an ordinary worker's family, and the family is very poor. He wants to change his fate with knowledge, but his fate is ill-fated and his academic performance is not good.
He decided to give up studying and go out to work early to make money, but because he was too young, he had no place to use him, so he had to go back to school. But at this time, he found himself interested in mathematics. When he was studying mathematics, he felt that he could really appreciate the fun of learning. But he is blind in all subjects except mathematics and can only graduate from a junior college hastily.
Yu Jianchun University majored in animal husbandry. After graduation, he didn't engage in this field. He looks for a job and works everywhere. He worked as a security guard, carried a big bag and worked as a construction worker on the construction site, but despite this, he still did not give up his love for mathematics. He often keeps a stack of draft papers around him so that he can calculate easily when he has an idea.
Finally, he got a job delivering express delivery, so that he could deliver express delivery during the day and have enough time to study math at night. Yu Jianchun often said that mathematics is no longer my hobby, it has been integrated into my life and blood.
Happened to meet the carmichael.
Years of work and life have exhausted Yu Jianchun physically and mentally. When he is tired, he likes to go to the local library to read books about mathematics. Occasionally, after delivering the courier in colleges and universities, he will take advantage of his position to go to the university library to read books. With natural love and acquired efforts, Yu Jianchun's mathematics level has quietly advanced by leaps and bounds. Once, when he was looking up information, he learned a math problem called "Carmichael number".
Carmichael number, also known as "absolute pseudo prime number". The American mathematician Kammeyer discovered the law of this number in 19 12, which shocked the world at that time. We ordinary people may be surprised to hear this name, and we don't even know what it is, but in the field of mathematicians, it is a difficult problem that has puzzled mathematicians for nearly a hundred years.
Yu Jianchun also began to solve this problem, but without the help of professionals, his calculations would always be wrong, so he sent stacks of operation procedures to many university professors, hoping for guidance. But the letter he sent out was like a stone sinking into the sea, and there was no reply.
One day on 20 16, Cai Tianxin, a professor at Zhejiang University, received a pile of draft paper. He opened it and looked at it. Numerous formulas made him think it was a question sent by a student. But later, he was surprised to find that someone had solved the Carmichael number, and there were continuous cubic numbers and natural cubic numbers on the paper. He knows that such an answer is impossible for ordinary people. Hurriedly wrote back and invited Yu Jianchun to come to Zhejiang University in person.
It was a blockbuster to give a speech at the university.
After receiving the reply from the professor of Zhejiang University, Yu Jianchun was both worried and happy. He is glad that his answer has finally been answered. What worries him is that he has never had such an experience and doesn't know how to convince others of his answer. But he knew this was a once-in-a-lifetime opportunity. At the age of 33, he came to Zhejiang University wearing an ill-fitting suit.
Professor Cai Tianxin couldn't believe his eyes when he saw Yu Jianchun. He can't believe that such an ordinary person has solved such a math problem. But as the saying goes, "All that glitters is not gold." He hastily convened an academic exchange meeting.
At the academic exchange meeting, Cai Tianxin solemnly introduced Yu Jianchun and his experience to his colleagues. In the face of many academic authorities, Yu Jianchun is particularly stiff. In order to ease the embarrassment, Cai Tianxin quickly asked Yu Jianchun to start answering questions. At first, Yu Jianchun was so nervous that his hands holding chalk were shaking. Professor Cai Tianxin constantly encouraged Yu Jianchun.
Slowly, Yu Jianchun looked at his rather neat handwriting, as if he had met one old friend after another. He began to perform in ecstasy, and the professors in the audience were gradually attracted by Yu Jianchun's operation process. When he completely solved this world problem, the audience burst into thunderous applause. People were surprised to see this man with only a college degree and exclaimed in succession. Sure enough, interest and persistence are the road to success.
Shocked the world, but also had a simple wish.
After the academic exchange meeting, Yu Jianchun shocked the world. Professor Cai Tianxin hopes to recruit Yu Jianchun into his own school and take away the graduate students. However, because Yu Jianchun only has the ability in mathematics, he may not be able to graduate smoothly, and this wish will go away. Some companies want to recruit Yu Jianchun as a consultant of the group, but he says he just wants to concentrate on mathematics.
Being famous in one fell swoop also brought troubles to Yu Jianchun. Many media came to interview this ordinary person who solved the world's problems, which worried Yu Jianchun, who was not good at words. Only when the media asks about math problems, Yu Jianchun's eyes will shine and he will work tirelessly to solve math problems.
Yu Jianchun was once asked by the media that you have made such great achievements in the field of mathematics. What is your wish? Honest and frank Yu Jianchun said, "I want to get married and have a family". What a simple answer! I didn't ask too much, and I didn't seek fame and fortune. I just want to start my own family. Simplicity is the precious spirit of Yu Jianchun.
It's a long way to go, but it's Xiu Yuan. We believe that Yu Jianchun will still maintain his love for mathematics in his later years, and will certainly achieve higher achievements under the guidance of his major. Because of love, he chose mathematics, because of persistence, mathematics chose him. I also believe that someone will take a fancy to this simple guy and form a happy family with him.
