Not only did he not show the talent of "child prodigy" from childhood, but his grades were not top-notch until junior high school and high school.

But in this way, Liu Lu, who looks ordinary in all aspects, became the youngest professor at the age of 2 1. How did he complete the "road to counterattack"?

A "poor student" with serious partiality

Liu Lu was born in an ordinary family in Liaoning. My mother is an engineer in an enterprise and my father is a logistics worker in a state-owned enterprise. Because both parents are science students, perhaps because of the influence of family atmosphere, Liu Lu likes studying mathematics since he was a child.

But in fact, when he was in primary school, junior high school or even high school, his academic performance was not outstanding. Liu Lu also said that he didn't really have any talent. He just liked mathematics, so he paid special attention to it.

By the time of junior high school, Liu Lu had been obsessed with the study of mathematics.

What he learned in mathematics and number theory is not something that can be learned in textbooks, but because of this, his concentration on mathematics has made other subjects light up red, and even his favorite math scores can only linger on the passing line.

Because of his academic performance, the teacher communicated with his parents by telephone more than once, but it was useless for parents and teachers to worry. Even though his mother found that the light in his room was on at eleven o'clock at night, in fact, Liu Lu was still studying number theory which had nothing to do with the exam.

Fortunately, Liu Lu, who played an outstanding role in the senior high school entrance examination, was admitted to a local key middle school.

In the most critical high school, Liu Lu still "goes his own way" and doesn't concentrate on preparing for the exam. Although his parents were also worried about his future, they finally chose to support Liu Lu's decision and let him go his own way.

So Liu Yi was admitted to the Mathematics Department of Central South University with a score of 56 points exceeding the key line. This score was somewhat inferior among his classmates who were admitted to Tsinghua Peking University, Oxford and Stanford, but he thought it was enough.

Liu Lu was born for mathematics.

In Liu Lu's view, it doesn't matter which university you go to. The important thing is that no matter which university he is in, he will study math. So Liu Lu, who is determined to study number theory, finally has more time in the university where his study and life are very easy, so that he can start studying mathematics without fear.

In college, his grades are still not top-notch, but the library in the university gives him more opportunities to contact with mathematical research.

In his sophomore year, Liu Lu began to learn mathematical logic. At that time, some students asked him questions and found that his ideas were not the same as those of others, and they were not the same as those taught by teachers. His method is often simpler and more effective, and it is not easy for people to think of it. Therefore, he has a different view of him.

But in this process, the change of students' views is not worthy of Liu Lu's attention. What interests him is a world-class mathematical problem called "Sitapan conjecture".

This is a conjecture about the probative power of Ramsey's second coloring theorem put forward by the British mathematical logician Sitapan in the 1990s.

This conjecture has been put forward for many years and has been proved by many mathematicians all over the world for many years. Liu Lu, who was extremely interested in mathematical logic and regarded mathematics as his life, was also interested in this conjecture.

In Liu Lu's view, this is not a world-class math problem, but an unsolved one, which is as wonderful as usual after he solves it.

"Learning scum" counterattack, solving math problems at the age of 20

Because of studying mathematics all the year round, Liu Lu and traditional scholars have different understanding of mathematical logic. Coupled with his keen interest in mathematics, Liu Lu came up with a method to prove this conjecture after two months of contact with Sitapan's conjecture, so he spent a whole night writing out the proof process completely. In order to prove his verification process, Liu Lu sent the verification process to the international authoritative magazine Symbolic Logic.

At that time, Liu Cai was a junior, and young people always had many ideas, so when Liu Lu sent this letter, he didn't use his real name, but signed it "Liu Jiayi", so many people don't know it now. In fact, Liu Jiayi who confirmed Sitapan's conjecture was Lu Lu himself.

Gold always shines. Although it has been called a "poor student" before, when Sitapan's conjecture proof process signed by Liu Jiayi was accepted by Symbolic Logic magazine, it immediately caused a sensation in the mathematics field.

At that time, the famous mathematician Dennis Hans Jefford was very excited after seeing this proof process. He studied Sitapan's conjecture for many years and failed to get the result. He was shocked and admired when he learned that this verification process was worked out by a junior in China. He also personally wrote a letter to Liu Lu to express his praise.

Liu Lucheng, aged 2 1, is the youngest professor.

Liu Lu went from a "school scum", from a minor student who was not favored by others to a world-class math problem at the age of only 20, relying on, as he himself said, his dependence and research on mathematics.

In daily life, Liu Lu can't live without mathematics just as fish can't live without water. What can't be done with this spirit?

Liu Lu verified the achievements of "efforts" with his own practical actions. The news that Sitapan's conjecture was verified shocked not only the world mathematics community, but also the domestic public opinion.

Liu Lu, who was regarded as a poor student since childhood, was recognized by the international mathematics magazine at the age of 20, and his school, Central South University, began to pay special attention to him.

Professor Hou Zhenting, a doctoral supervisor, accepted him as a disciple and used his own resources to create learning conditions for him.

After hearing the news, three academicians of the Chinese Academy of Sciences also signed a letter to the Ministry of Education, hoping that the country could attach importance to this young mathematical genius, so Central South University made an exception and hired Liu Lu as a full professor, and Liu Lucheng, 2 1 year-old, was the youngest professor.

It is not difficult to find out how such a counter-attack road is taken. First of all, interest is the best teacher. Liu Lu's greatest interest is mathematics. One of the most important reasons is that he is willing to learn and like to explore.

Secondly, no matter what people around him think, he can make unremitting efforts to explore and discover and work hard in this direction. God will never be unkind to those who work hard!
