Today we are going to show you a true story, the counterattack of the bottom people in real life. He is a courier brother. With his innate talent in mathematics, he has solved the century-old problems in mathematics. Not only was he invited to the podium of domestic universities, but also international mathematicians praised him. He completely changed his life by his own efforts. The hero's name is Yu Jianchun.
Yu Jianchun was born in Dabie Mountain, Xinyang, Henan. As a student, his academic performance is average and he has no special talent. I went to vocational high school in Xinxian County, and went to Zhengzhou Animal Husbandry College after graduation, majoring in animal husbandry. After graduation, Yu Jianchun changed jobs and moved to Beijing, Shanghai and Dongguan because she didn't find a counterpart job. After going back and forth to Henan as a logistics clerk, life will be stable. After work, his leisure style is monotonous, that is, lying on a "simple chair" made of several red bricks in the dormitory to calculate mathematical formulas.
In fact, at school, Yu Jianchun is not good at math. He doesn't like math and geometry, not to mention more profound calculus. He is just naturally sensitive to pure numbers, and the calculation formula is intuitive. The seemingly unreliable way of solving problems has enabled him to solve the problem of Carmichael number that has plagued the mathematics community at home and abroad for more than 0/00 years. In fact, as early as eight years ago, he had solved this difficult problem, but he didn't know whether the solution and answer were correct. Therefore, in the past eight years, he has been trying to contact some excellent mathematicians in China and send them emails with his own answers, but he has never got a reply. Until Cai Tianxin, a professor of mathematics at Zhejiang University, saw his email, got in touch with him and invited him to give a live demonstration at Zhejiang University.
On that day, in addition to Professor Cai Tianxin, there were three doctoral students, a postdoctoral fellow and an associate professor majoring in number theory. Yu Jianchun walked onto the platform in his overalls. At first, she was so nervous that her hands shook, and slowly she was immersed in the numbers. From 10: 30 to 12: 00 in the morning, Yu Jianchun deduced his five mathematical discoveries in one breath, during which he didn't read his notes and reference materials once. Two of the five findings have been confirmed, and Professor Cai Tianxin highly praised their research results.
A China courier boy solved a century-old math problem. After the domestic media reported, foreign media also paid attention. Yu Jianchun's new algorithm has been appreciated by international academic circles, and William, a mathematician at the University of Missouri.
Banks said: once this algorithm is confirmed, it can become an important discovery in the field of Carmichael numbers. Yu Jianchun said that he discovered the new algorithm by instinct. When the inspiration about carmichael appeared, he wrote a book, from which the discriminant of Carmichael number was deduced step by step. Now, with this achievement, Yu Jianchun has completely changed his life. He was hired by Zhejiang Silk Road Group (one of the largest silk manufacturing enterprises in China), and the chairman of the company promised to give him enough time walk for his interest and talent in mathematics.
After reading Yu Jianchun's story, I believe everyone is happy for him. It is really not easy for a courier to step onto the international mathematics stage. But I pay more attention to one person-Professor Cai Tianxin, a "Bole" in Yu Jianchun. I can't help but wonder why Yu Jianchun's great discovery has repeatedly hit a wall in front of many outstanding mathematicians in China, and why he sent so many emails before but no one responded. China has a population of 65.438+0.4 billion, and there are still many talents hidden in the vast sea of people. We don't lack talents, what we lack is "Bole" like Cai Tianxin. Without him, China would have one less mathematician and one more courier!
