Sure enough, traffic is a double-edged sword, and when the vast majority of people cheered for Jiang Ping, the voice of smearing and attacking Jiang Ping also came.
Today, I swiped some bloggers who said that Jiang Ping's incident was reversed, saying that some people on the Internet thought that Jiang Ping's level was not enough, and Jiang Ping scored 83 points in mathematics in the high school entrance examination with a full score of 150. It is believed that she does not understand advanced mathematics at all, or that Alibaba falsified her results, or that her math teacher took the test on her behalf.
First of all, if Alibaba falsified its results, then why did he go all the way to Lianshui College to find Jiang Ping and ask her to do questions on the spot to verify her level? Assuming that Ali already knew that Jiang Ping's grades were forged, and knew that Jiang Ping's level was not enough, why did he move out more materials by himself, expose the math problems and proof process on the blackboard to the world, and expose himself to more black materials? In the Internet era, so many eyes are staring at it, and the Damo Academy is too bold, right?
It was when the Damo Academy saw Jiang Ping's results that they were afraid that someone would take the test on their behalf, so they went to the field for verification, and Jiang Ping solved the exam questions on the spot, so they dared to announce the preliminary list. Therefore, the inference that the math teacher will take the test on behalf of the teacher is basically not valid.
This event began in 2018, and now it is in its sixth year, it is sponsored by Alibaba, and it is a very serious matter, the Damo Academy may want more people to know about this event, but the possibility of deliberately falsifying and falsifying the results of Bo traffic is still very small, because the price is too great, and the organizing committee has mathematicians at the level of Zhang Yitang and Tian Gang, and there are mathematics professionals from various famous universities around the world, which is a mathematics competition that attaches great importance to its own credibility (integrity).
Secondly, they questioned the question given to Jiang Ping by the Dharma Academy on the blackboard, Jiang Ping just copied the answer on the blackboard, and Jiang Ping copied it with loopholes, copying Sigma as /2, gamma as the reverse version, and copying the last item of the Yu Yuan formula as an exponent.

So the questions on the blackboard, is Jiang Ping's answer copied when she answers? There is still a threshold for mathematics, as a layman, I don't dare to jump to conclusions, but turn to experts for help, my friend North Star is a mathematics professor at a university in the United States, and he usually writes science fiction novels, this is his answer to this question on Weibo:
Now some netizens question that the answers in Jiang Ping's video are suspected of being fake. I know that there are a lot of math experts on the Internet, but I haven't seen anyone take out Jiang Ping's solution. I took a moment to completely review Jiang Ping's proof in the video, and the Remark in it is my comment. Sorry, my Latex is only available in English. (Erxiang Note: He used LaTex in English at the beginning, and today with the help of netizens, he edited LaTex in Chinese and wrote a Chinese version and sent it to me)
The main conclusion of Mr. Beixing is that this certificate is not written in a standardized manner, as long as you have a master's degree in mathematics or above, you will not write it like this. But there is no mathematical error in the proof, so it must have been written by Jiang Ping herself. And equations (4) and (5) are general conclusions. Although correct, it is redundant in the solution and not needed at all in the complete solution. In other words, if you copy a ready-made solution, formulas (4) and (5) will not appear. Therefore, the blackboard is Jiang Ping's thinking process, and it is impossible to copy ready-made solutions.
In response to those small mistakes (sigma is written as /2, and gamma is written backwards), Mr. Beixing thinks that a 17-year-old secondary school student writes a blackboard that is not standardized, and there is no fuss. If it's fake, why not make it more perfect? It's not difficult to find someone who understands math to check the blackboard before making a video, right?
Some people also say, what is the meaning of the definition field w is not equal to zero? For CSC to be meaningful, W should not be equal to 2*m*pi. Teacher Beixing's reply was "The topic is probably made of a video temporarily, and it is not very rigorous, and it has nothing to do with Jiang Ping", which also proves that this is not a pose, otherwise the person who made the question would have thought more carefully in advance.
In addition, Jiang Ping used LaTex to submit the answer sheet, and those people questioned how it was possible for a secondary school student to be familiar with the use of LaTex? Could it be that she is still a computer genius? In this regard, Mr. Beixing's reply is that LaTex is not a profound and difficult thing to learn, and I can almost use it proficiently in less than a week, and I don't need a computer genius at all.

About Jiang Ping's high school entrance examination mathematics full score of 150 points, Jiang Ping took the test 83 points, one of the reasons I heard is that she did not finish the paper, this is actually not difficult to understand, the questions in the high school entrance examination are all calculation questions, many times it is also a test of proficiency, for a rural girl with a very ordinary family background and a father working outside, there is no chance to go to cram school to brush the questions, and the speed of solving the problems will naturally not be very fast.
Another very important reason is that the ability to calculate and reason for logic in mathematics are completely two abilities. Mathematics at the elementary level is all about computing ability, and the higher you go, the higher the requirements for abstract thinking and logical thinking skills. A math expert I know once said that AIME (an intermediate-level middle school math competition in the United States) can be passed by brushing questions, but above AIME, it depends on talent.
The Fields Medal-winning Korean mathematician I mentioned earlier, Heo Jun-il, did not show much mathematical talent as a child, but was fond of poetry and literature. His colleagues described him as a slow-moving person, saying he "speaks slowly, pauses frequently, uses his words carefully, and presents himself in a calm, peaceful way that borders on meditation." If you talk to him about calculus, it will take less than 5 minutes to conclude that this person can't even pass the qualifying exam. He's just too slow. ”
But Xu Juner's slowness is a unique way of thinking, and he thinks that more time should be spent to find a clearer and more attractive method, and Jiang Ping may also be such a slightly slow mathematical genius.
A big reason why Jiang Ping's incident is so swiping the screen and has such a big impact on us ordinary people is that this story is too inspirational and cool, just like a female version of a sweeping monk defeating Wudang Shaolin masters, which is too inconsistent with the thinking logic of ordinary people, so it is not surprising that there are doubtful voices. In fact, there is nothing wrong with questioning any incident, but if it is biased or even malicious at the beginning, it is very problematic.

Although I believe that Jiang Ping did not cheat, but I think it is quite difficult for her to win the final award, first of all, the difficulty of the preliminary round and the final round is not the same level, the preliminary round is equivalent to the difficulty of the second year of undergraduate, and the final is the difficulty of the entrance level of mathematics doctoral students, and the difficulty has increased by several grades. Jiang Ping has only been teaching herself college mathematics for two years after all, and she wants to PK with these masters who have started systematic math training in elementary school, and it may still be a little bit worse.
The second is that the rules for the preliminary round and the final round are different. The preliminary round is 48 hours, which is an open-book competition, and you can consult the information, but the final round is 8 hours, and the closed-book examination is not available. This will definitely have some impact on Jiang Ping, who is still a little lacking in mathematical reserves.
The third is what one of my old classmates said, those top players haven't fully developed yet, they probably haven't used all 48 hours, anyway, they can get to the finals. These finalists are all top masters, and they often participate in various mathematics competitions, so it is really difficult for Jiang Ping to win the award in the finals.
But it is quite remarkable that she can rank 12th in the world in the preliminary round, because the difficulty of the preliminary round questions is also quite large, many of them are professional players in the mathematics department of famous universities, in addition to Peking University Tsinghua University, it is said that many are Putnam fellows (the top five of the famous undergraduate mathematics competition in North America), she can kill a group of masters in seconds, which is really encouraging.

As Teacher Lao Dongyan said: "In my opinion, people do not hesitate to praise her, not only because of her good results in the competition, but also because she has lived a beautiful life of freedom:
Have courage, love, vigorous vitality, and be willing to pay and persist for the things you love, and break through the invisible shackles imposed by society.
Who says girls can't learn math well? Who says that secondary school students with a low starting point don't deserve to have big dreams?

In our society, there are too many invisible shackles, too many tangible disciplines, in short, you are required to obey and follow the crowd, and be content with the position of the society for you.
In such an atmosphere, many people will also set limits on themselves, put on "paper handcuffs" for themselves, and become guards who imprison themselves.
As a prisoner under his care, he agrees that he is not worthy of dreams, and that he is not worthy of wishful thinking about pursuing things that seem unattainable to his position.
However, social injustices and prejudices cannot be changed by individual conformity. On the contrary, to conform to the rules and conform to society's position on oneself is precisely to add to social injustice and prejudice.
Only by having the courage to try and pay can we break through, and only then can we change our lives and change the existing injustices and prejudices in society.
As an individual, although it is difficult for us to save ourselves from being disciplined by society, we can at least retain the freedom not to accept the results of discipline.
That is to say, whether or not to accept the discipline of society should be decided by oneself, and we should not set psychological limits because of society's positioning of us.
You have the right to live the way you want to be, and you can live the way you want to be. ”
That's a good point, breaking those invisible shackles, eliminating the prejudice of the disciplined society, not setting limits for yourself, having the courage to try, being willing to pay, finding your passion, insisting on your love, and living yourself as you want, this is the most touching and most noteworthy perspective of Jiang Ping's miracle.
