In TV series, we can often see an ordinary grassroots counterattack all the way to the bridge of kings. There are also many cases in real life. Many people want to "counterattack" to become kings, but that's just imagination. The success of the counterattack also requires a lot of efforts to become a better self! Today, I want to tell the story of an ordinary courier who successfully counterattacked and became a mathematician.
We may wonder if he has a high degree and just became a courier. But his education is not high and his grades are not good. High school is a vocational high school. After graduation, I went to Zhengzhou Animal Husbandry College, majoring in animal husbandry. After graduation, he also faces the same graduation problems as many people, and it is difficult to find a job! He found many jobs, but none of them were suitable, so he had to go back to his hometown to be a courier.
In his spare time after hard work, he became interested in mathematics. I started my journey to study mathematical problems. Although he didn't study mathematics systematically when he was studying, it was very surprising that he was able to deduce the formula by his intuition about mathematics, and he actually solved the Carmichael number that no one could crack for a hundred years. Although he worked it out, he didn't know how to tell others his solution. Moreover, with his education and occupation, who will believe that he can solve this century-old mathematical problem?
Let others know that they have solved the problem. He started sending emails to famous mathematicians with his own solutions, but no one answered him. Instead of giving up, he continued to send emails to mathematicians. Finally, God rewarded hard work until Cai Tianxin, a professor of mathematics at Zhejiang University, saw his email and decided to invite him to the university for deduction.
The professor was not the only one that day. He also invited several students and associate professors. This made Yu Jianchun nervous when he was on the podium for the first time, but after the lecture began, he gradually immersed himself in his own mathematical world, so he was not nervous. All the formulas in the middle are derived continuously. Everyone was shocked when the result came out. I didn't expect an ordinary courier to solve a century-old problem in mathematics. Through this, he also turned himself into a mathematician.
After reading Yu Jianchun's story, we know that "counterattack" not only happened in TV series, but also happened in our lives. Yu Jianchun's success depends not only on his extraordinary talent, but also on his not giving up easily. If he gives up sending emails to mathematicians and professors, his findings will not be known to everyone, so he will continue to be an ordinary courier, and no one knows that the problem has been solved.
