The king of great powers struggled for a long time and rushed to the ground to catch up. -Li Bai's "Nanling children don't go to Beijing"

In this world, there are not so many classes and differences at all, and there are no small people and humble lives.

The key is whether you have dreams, talents and persistence that others can't understand. This is the only way to link mediocrity with Excellence.

The so-called persistence does not distinguish between high and low, and the persistence of scientists is persistence. The dreams of ordinary workers in factories are as important as persistence. The genius of this issue comes from an ordinary village and is an ordinary courier brother.

He kept learning and finally solved a math problem that no one had solved for a hundred years through self-study, but he didn't expect that even if it was solved, it didn't bring much change to his life. Why?

1. Born in poverty, he constantly strives for self-improvement and is unwilling to be buried in a small city.

Yu Jianchun is just an ordinary young man from Xinyang mountain area. He was born in 1983, and his family in Yu Jianchun is not good.

His parents have been farmers for generations, and he didn't have a good environment to receive education since he was a child. This is not the most fatal blow to Jianchun, who at least had enough food and clothes in his childhood.

But as he grew up, his parents left him forever in an accident. At this time, Yu Jianchun found that even food and clothing became a problem.

Apart from going to school to earn money to support himself, the only pleasure in his life is learning mathematics, but unfortunately, the pressure of life makes him unable to concentrate on his studies.

Except for mathematics, other grades were not particularly excellent, but with his research on mathematics, he later came to a college, Zhengzhou Animal Husbandry Engineering Advanced Science and Technology College.

Before he was admitted to a college, Yu Jianchun had a small climax in his life. In the process of solving problems systematically in senior high school, he suddenly and unintentionally deduced the law of turning horses.

This law, also known as the four laws of number theory, opened his way to mathematics. His school is related to animal husbandry, but he is not interested in subjects other than mathematics.

On the contrary, he is very interested in mathematics. When the school organized students to participate in animal husbandry activities and systematically studied animal husbandry knowledge, he secretly took out a piece of toilet paper, took out a pen and calculated related mathematical formulas.

At the beginning, because of his excellent math performance and unique math performance, he aroused the curiosity of some students in school.

But then everyone's curiosity about him gradually faded. After graduation, Yu Jianchun faced another difficult problem in his life.

Second, I have traveled all over the country, and my love for mathematics has not diminished.

Because the threshold of colleges and universities is not high, after graduating from animal husbandry colleges, he doesn't know where he will go or where he will find a job.

If he is only engaged in occupations related to animal husbandry, he is unwilling. Only then did he realize that he didn't have to be limited to this, and maybe he could go out and see a wider world.

Maybe this can bring him some different feelings, so he went to a bigger city by train, and Yu Jianchun's diploma was not high.

However, he has a big dream and has worked all over the country. He has been to Beijing, Wuxi, Dongguan, Suzhou and Guangdong.

But his job is not good, because he is just an ordinary person with a college degree. Fortunately, Yu Jianchun does not exclude the creation of wealth through labor.

But for him, it doesn't matter what job he does. When the security guard delivers the express delivery, the only requirement is that there is a place where he can continue to study the mathematics he loves.

In recent years, wherever Yu Jianchun goes, it is inevitable to ask his dormitory to have neat tables and chairs. If not, he will do it himself.

In his spare time after work every day, he does math in the dormitory. The workmates didn't understand his behavior and even laughed at him, but he didn't expect that Yu Jianchun did a famous thing later.

Third, with my love for solving problems, I suddenly became famous in China.

In the process of continuous contact with the deduction of number theory, Yu Jianchun came into contact with such a law, which is called Kalman number according to the law that people all over the world are familiar with him.

Carmichael number is just a pseudo prime number. When Yu Jianchun first came into contact with this difficult problem, he found it interesting and inspired.

19 12 years, the absolute pseudo prime number was first discovered by American mathematician carmichael, hence the name. 100 for more than a year, countless experts and doctors in the field of mathematics at home and abroad have been advancing wave after wave, trying to study the mystery, but little has been gained.

But I didn't expect that in the process of continuous derivation, Yu Jianchun actually worked out this series, and the research process took him four years.

It suddenly occurred to him that if we use a formula in a different way of thinking, it may be possible to get rid of Cammeyer's grams. If this research is really successful, it will definitely be a great progress in mathematics.

He visited the local university with excitement and fear, and at the same time contacted the celebrities in the domestic mathematics field in various ways, asking them to prove the correctness of formula calculus for themselves.

But it's a pity that I sent so many letters and asked so many professors. At this time, his heart cooled down bit by bit.

He is just an ordinary courier. How can anyone really care about him and understand his research results?

Just when he was about to lose heart, he suddenly received a reply from someone. This man is Cai Tianxin, a professor of mathematics at Zhejiang University.

Fourth, domestic and foreign media rushed to report and stood on the podium to calculate the results.

After seeing the letter sent to him, Professor Cai immediately contacted him, hoping that he could come to Zhejiang University and count his achievements in mathematics in front of everyone.

Professor Cai attaches great importance to his grades and is nervous to hear the news. Zhejiang University is the cradle of academic gestation.

This demonstration proved the feasibility of his plan. At the same time, if he succeeds, it really means that his four years of hard work have not been in vain. Yu Jianchun was still impressed by the unusual experience at that time.

At first, after all, it was the first time to stand on the podium. He was very scared. The people sitting below are all national first-class mathematicians, doctors and experts.

But when he started talking about his research results, he suddenly found confidence. He deduced all the complete formulas bit by bit according to his own ideas, without even reading his notes.

This deduction took two hours, but the doctors and experts who sat down were very attentive. After reading it, Cai Tianxin also approved the formula proposed by Jianchun to a certain extent, and thought that Yu Jianchun had indeed made some achievements in carmichael's formula.

Cai Tianxin intended to send Yu Jianchun to the Mathematics Department of our school, but after all, he is only a college graduate studying animal husbandry.

Even if he is talented in the Department of Mathematics and requires all-round development, he probably won't graduate from graduate school, so even if he worked out a world-class mathematical formula, Yu Jianchun's life hasn't changed much. The domestic and foreign media soon learned this fact.

Reporting Yu Jianchun's deeds, and for him, working out a world-class mathematical formula, the biggest change in his life is to quit his logistics job and enter a brick factory, which also gives him more time to continue studying mathematics.

The world never lets people with dreams down, and so does Yu Jianchun. Many people don't recognize Yu Jianchun's achievements, thinking that he spent four years studying such a difficult formula, and in the end he was still just a brick factory worker. But in fact, it doesn't matter to Jian Chun. He didn't study mathematics to be famous or to be recognized by many people.

Just to calculate the happiness and joy we get at that moment, if we make all our dreams too utilitarian.

Then success or failure will become very important to us, affecting the individual's mentality and development.

However, if we only regard dreams as a hobby to realize personal values, then the realization of dreams will become a shortcut and a pleasure.
