Chinese version of the Soul-Catcher: Henan courier address critical problem in mathematics-courier, math, mind catcher-IT information
On July 23 the United States media said, in the 1997 movie the soul catcher, played by Matt Damon's weier·hengting is a cleaner, but by virtue of his talent to unravel a complex mathematical problem; he was still with the help of Professor, overcomes the devil, finds his love. This 126-minute film won the Academy Award, United States film critic luojie·aibote called it "completely expected."
United States, the Washington Post, July 19, and Ebert probably will feel more surprise. United States cable news network reported that a similar story seems to be staged in China. 33 years old from Henan of China express Yu Jianchun math problem solving at higher efficiency, which surprised experts.
Reported, even though this method has not been confirmed by an independent third party, but Yu Jianchun has been described as the real version of the weier·hengting. Just don't ask him about the movie of the Soul-Catcher--he said he has never seen. More weier·hengting's character and should not be compared Yu Jianchun, Hunting is a rough South of Boston, while Yu Jianchun, but very shy and self-effacing, in an interview, he said he was "unresponsive".
Yu Jianchun technical school after graduation working for a courier company and never received higher education. He was a courier for migrant workers, will run at the first time to the local try visiting professor of mathematics at the University.
Department of mathematics, Zhejiang University, Professor CAI Tianxin on United States cable news network correspondent says: "he has not received systematic training in mathematics or learned advanced mathematics courses. What he has is intuitive and extremely sensitive to digital. ”
CAI Tianxin said Yu Jianchun method of solving problems "very imaginative." Yu Jianchun research focused on Carmichael numbers, a Pseudoprime (pseudo Prime). There are mathematical theorems, such as Fermat's little theorem, can tell if a number is a prime number. At first glance, Carmichael number appears to be consistent with the mathematical theorems of prime numbers. But after repeated verification, Carmichael number is not actually Prime.
In theory, there are infinitely many Carmichael numbers, but they are rarely found. In 1910, the R.D.Carmichael found 15 Pseudoprime, where the first 5 numbers is 561, 1105, 1729, 2465, 2821. Tell which is a real number a prime number, which is the pseudo-Prime, is a very difficult task.
Yu Jianchun said: "all I found is with their intuition, inspired and wrote a few strokes. ”
Though will have to wait for third parties to his methods, but Yu Jianchun may have found an easier way Carmichael number of distinguishable from the really prime. Chinese media said, Yu Jianchun has studied the issue for 8 years. He has consulted a number of experts, but CAI Tianxin experts was the first to give him an answer.
In June, Yu Jianchun CAI Tianxin invited to lecture at Zhejiang University. It was alleged that during his speech, Yu Jianchun did not see the notes or references, because of "numbers and equations in his head". The China daily newspaper reported, after listening to the shows Yu Jianchun, math experts believe his ideas "innovative", "partial result has some depth."
Reports that once the results are confirmed to be authentic, this is an important update to existing theories. Cai Tian Xin Yu Jianchun theory published in publications associated with a Carmichael number. Now, Yu Jianchun has become a local hero, got a work engaged in mathematical research, instead of courier.
Now single Yu Jianchun on United States cable news network reporter, his greatest wish is to get married and start a family. He said: "I most want is family, and then studied mathematics. ”
中国版心灵捕手：河南快递员解决重大数学难题 - 快递员,数学,心灵捕手 - IT资讯
7月23日报道美媒称，在1997年上映的电影《心灵捕手》中，由马特·达蒙饰演的威尔·亨廷是一名清洁工，却凭借自己的天赋解开了一道复杂的数学难题；他还在教授的帮助下，克服了心魔，找到了自己的爱情。这部长达126分钟的电影曾荣获奥斯卡奖，美国影评人罗杰·埃伯特称这“完全在意料之中”。
美国《华盛顿邮报》网站7月19日报道，或许埃伯特会觉得现实更出人意料。美国有线电视新闻网报道称，一个类似的故事似乎正在中国上演。来自中国河南的33岁快递员余建春以更高的效率解决数学难题，令中国专家吃惊。
报道称，尽管这一解法还未获得独立第三方的证实，但余建春已被誉为现实版的威尔·亨廷。只是不要问他有关电影《心灵捕手》的事——他说自己从未看过。更不要将威尔·亨廷的性格与余建春的做比较，亨廷是波士顿南部的一个粗人，而余建春却非常害羞，不爱出风头，他在接受采访时称自己“反应迟钝”。
余建春技校毕业后在一家快递公司工作，从来没有接受过高等教育。他是一名送快递的农民工，一有时间就会跑到当地最好的大学尝试拜访数学教授。
浙江大学数学系教授蔡天新对美国有线电视新闻网的记者说：“他既没有接受过数学理论方面的系统性培训，也没有学习过高等数学课程。他所拥有的是直觉和对数字的极度敏感。”
蔡天新称，余建春的解题方法“非常具有想象力”。余建春的研究内容主要是关于Carmichael数，一种伪素数（伪质数）。有一些数学定理，比如费马小定理，可以分辨一个数是否为素数。乍看之下，Carmichael数等素数似乎符合这些数学定理。但经过反复验证后，Carmichael数实际上并不是素数。
从理论上讲，有无限多的Carmichael数，但它们很少被发现。1910年，R.D.Carmichael发现了15个这样的伪素数，其中前5个数是561、1105、1729、2465和2821。分辨出哪些数字是真素数，哪些是伪素数，是一项非常艰巨的任务。
余建春说：“我的所有发现凭借的都是自己的直觉，有灵感了就写上几笔。”
尽管还需要等待第三方证实他的解题方法，但余建春可能已找到一种更简便的方法将Carmichael数从真素数中区分出来。中国媒体称，余建春已对这一问题展开了8年的研究。他曾咨询过多位专家，但蔡天新是第一个给他写回信的专家。
今年6月，蔡天新邀请余建春到浙江大学进行演讲。据称，在演讲过程中，余建春没有看一眼笔记或参考资料，因为“数字和公式都在脑子里”。《中国日报》报道称，听完余建春的演示后，数学专家们认为他的想法“新颖”、“部分结果有一定深度”。
报道称，一旦这一研究成果被证实是真实可信的，那么这将是对现有理论的重要更新。蔡天新打算将余建春的理论发表在与Carmichael数研究相关的刊物上。现在，余建春已成为当地的英雄人物，得到了一份从事数学研究的工作，而不再是快递员。
现在还是单身的余建春对美国有线电视新闻网的记者说，自己最大的愿望是结婚成家。他说：“我最想要的是家庭，然后才是研究数学。”
