As the saying goes, "A swift horse is common, but Bole is not." A talented person, if not appreciated by Bole, will eventually be buried. In other words, if someone discovers the hidden potential of "a swift horse", then a once seemingly ordinary little person can also achieve great things. Yu Jianchun, a busy courier, was invited by Zhejiang University to give a talk. Everyone was shocked, because this classic mathematical problem that had puzzled mathematicians for a hundred years was actually solved by such a humble "nobody". Yu Jianchun's experience is simply a novel with ups and downs.

Before 2065438+July 2006, the academic circles knew nothing about the name Jianchun. Because at that time, Yu Jianchun was just a hard-working courier. Although Yu Jianchun got good grades in mathematics since he was a child, he failed to enter an ideal university in the college entrance examination because of his serious partiality. So in the end, Yu Jianchun had to go to a junior college. After graduation, I could only find some manual labor to support myself.

However, this may not be a bad thing for Jianchun, because he can save the tedious entertainment in business, so that he can have time to continue studying his favorite mathematics. What's more commendable is that Yu Jianchun often goes to the library to borrow books related to mathematics after work. Later, he inadvertently noticed the Cammeyer number, a century-old mathematical problem.

With his sensitivity to numbers and natural intuition, he found five groups of numbers. What bothers Yu Jianchun, however, is that he doesn't know whether his deduction result is correct. So he sent an email to famous mathematicians and professors all over the country, hoping that they could help him verify the results. It's a pity that these emails ended up sinking into the sea.

For eight years, no professor replied to his email, and no one helped him verify the results. Indeed, for many professional mathematicians, finding Kammeyer number is a mathematical subject full of great challenges. The difficulty of such a task is equivalent to finding a few grains of sand in the vast universe. So, how can a small courier solve such a difficult task?

Despite repeated rejections, Yu Jianchun did not lose heart. Finally, at the critical moment, a professor named Cai Tianxin chose to help him. Cai Tianxin was born in 1963, and was admitted to Shandong University on 1978. Later, after receiving his doctorate from Shandong University, he continued to devote himself to academic research. Cai Tianxin's main achievements are addition equation and multiplication equation, which provide new and open mathematical ideas for many basic and classical mathematical problems.

He has been invited by major universities and scientific research institutions at home and abroad to give academic reports for more than 400 times. However, Cai Tianxin is not a rigid mathematician image in the traditional public impression. 20 13 Cai Tianxin's prose even won the Excellent Poetry Award. 20 14 Cai Tianxin's mathematics book "Mathematics and Human Civilization" has been widely praised since its publication. It can also be seen that Professor Cai Tianxin really loves mathematics, and is also empathetic and good at * * *.

Therefore, Professor Cai Tianxin did not neglect like other professors after receiving the email from Yu Jianchun. Together with his colleagues, he confirmed two sets of correct results. At the same time, Yu Jianchun finally became famous and was invited by a famous school to give an academic report. Not only that, he also reached the peak of his career. Now, Yu Jianchun has worked for an information company engaged in big data research and started his new career plan.

Mathematics originated in ancient Greece, but in modern times, mathematics has been included in educational textbooks. 20 16 a courier named Yu Jianchun in Henan actually solved a problem that has puzzled the mathematics community for a long time. In the eyes of many people, Yu Jianchun's academic qualifications are not high, and his work has nothing to do with academics. But it is undeniable that the great influence of mathematics on human beings has become an indispensable part of our lives. In his spare time, Yu Jianchun likes to study these math problems, which is why he can shake the math world at one stroke. This shows the importance of mathematics in children's education and thinking transformation.
