Chapter 51 Who taught you mathematics?
"No, why do you all think there is a problem with question 5? There is obviously no problem. First prove that the function is a harmonic function, and then judge the convergence of the function..."
Tang Ding Seeing everyone raising questions about the topic, I quickly refuted it.
Listening to Tang Ding’s explanation, everyone gradually realized that there was nothing wrong with the question itself.
“It turns out that this is not exactly the same type of question as we have done before. It seems that we were deliberately led into this trap.”
"After all, this is a question for the finals. How can it be possible that every question is a direct copy of the questions we have done. These questions must have been reviewed by Professor Qiu personally, and there cannot be any problems."
Ning Chen also heard what Tang Ding said. Putting aside other factors, Tang Ding's idea was indeed correct.
Analysis and differential equations are not Tang Ding's main subjects. Being able to master the secondary subjects to this extent is enough to prove that Tang Ding does have strong professional strength.
However, Ning Chen didn’t think much and walked straight out of the examination room.
As Ning Chen said before, Ning Chen doesn’t want to compete with anyone, nor does he care about other people’s results.
The questions on the test paper were the only things Ning Chen had to face.
......
Two days passed quickly. After answering the last exam, Ning Chen's tense spirit could finally relax.
Based on Ning Chen’s estimation of his answering status, Ning Chen felt that he still had a good chance of getting the gold medal.
As for how many items you can get...
Ning Chen really couldn't say it accurately.
In the evening, several teachers came to Ning Chen and Tong Yicheng's room.
"Ning Chen, tonight you can prepare the contents of tomorrow's oral exam. Although we may not be selected, it is best to prepare in advance."
Ning Chen also knows about the oral exam. It is said that Professor Qiu Chengtong will ask questions in person at that time, but I don’t know what proportion the oral test scores will account for in the finals.
“Since only a part of the students are selected to take the oral exam, maybe it won’t be included in the final score at all, right?”
"Not necessarily, it may just be the top few in the written test. In any case, as long as you are picked, there is a high probability that the written test score is very good."
"Okay, nothing else will happen. , we won’t bother you. Normally, the awards ceremony would be held tomorrow afternoon. Anyway, if you can enter the finals, you have already made school history.”
Regarding the oral examination content, The tournament did not give any outline, and Ning Chen didn't know where to start preparing, so he casually looked through the books he brought.
I don’t know how much time passed, but there was a knock on the door outside Ning Chen’s room.
Tong Yicheng stood up and walked to the door. Looking through the peephole, he found that the person coming was Liao Jun.
Tong Yicheng quickly opened the door and asked:
"What's the matter, Teacher Liao?"
"The competition party just sent me a notice that Ning Chen needs to take the oral test tomorrow, and the time is 7 o'clock in the morning. You need to arrive ten minutes in advance to prepare for the exam.”
In order to prevent students from not receiving information in time, these messages will be sent to the teacher leading the group.
After listening to Liao Jun's words, Ning Chen and Tong Yicheng both understood the underlying meaning of this information.
"The oral exam is at 7 o'clock in the morning...probably the first one?" Tong Yicheng said.
"Yes, it's almost the first one. It is estimated that all the results of the written examination have been approved, and then the students and order of the oral examination have been determined."
Ning Chen's mood also changed. I am a little excited. Although the final results have not been released yet, based on the existing information, my written test results should be relatively good.
Of course, nothing can be finalized until the oral examination is over. "Okay, Teacher Liao, I understand. I will arrive at the examination room on time."
Liao Jun was naturally at ease with Ning Chen. After explaining these things, he closed the door and left.
The next morning, Ning Chen got up on time to wash up and have breakfast, and went outside the examination room at 6:40 to prepare.
At this time, except for the staff, there were no other students present in the examination room, which further proved that Ning Chen was the first to take the oral examination.
At 6:50, several teachers came to the examination room. Ning Chen followed the sound and found that one person looked familiar to him.
It is Qiu Chengtong, winner of the Fields Medal and academician of China and America.
Naturally, Ning Chen had never met Qiu Chengtong before, but had only seen Qiu Chengtong's photos online.
After several teachers entered the examination room, the staff saw that the time was approaching and said:
"Is Ning Chen here?"
"Teacher, I am Ning Morning."
"Well, you can go in for the oral exam."
"Okay."
Ning Chen came to the door of the examination room and knocked on the door. After getting a reply, he opened the door gently and walked in.
There were several teachers sitting in the first row of the examination room, and the one sitting in the middle was none other than Professor Qiu Chengtong.
Seeing such a scene, Ning Chen was inevitably a little nervous.
However, Ning Chen had a good psychological quality after all and quickly calmed himself down.
"Hello teachers, I am Ning Chen from Shengzhou University."
After briefly introducing himself, Ning Chen waited for several teachers to ask questions to him.
Qiu Chengtong looked at the boy standing in front of him and had a good first impression of Ning Chen.
Although Ning Chen hasn't said anything yet, Qiu Chengtong feels that Ning Chen is a very pure student just from the feeling.
That kind of purity is the love for mathematics from the heart, and will not be mixed with any other factors.
"Ning Chen, hello, I am Qiu Chengtong. The fact that you are standing here shows that your mathematical skills are very solid. I would like to know, who are your mathematics teachers at Shengzhou University?"
Ning Chen was also a little surprised when he heard Qiu Chengtong's question.
Ning Chen originally thought that Qiu Chengtong would ask him some professional questions about the competition.
But now, Qiu Chengtong seems to be just chatting with himself.
"Professor Qiu, my mathematics teachers Teacher He Sheng, Teacher Liao Jun, and Professor Yang Lianhua also gave me some pointers."
Naturally, Qiu Chengtong would not know the names of He Sheng and Liao Jun, but he still knew about Yang Lianhua.
“It turns out that Yang Lianhua is also at Shengzhou University.”
Qiu Chengtong has read a few of Yang Lianhua’s papers, but if we evaluate Yang Lianhua’s academic level, he can only rank among the best in the country at best. In the end, there is still a certain gap between Mizuki and the top teachers in the Department of Mathematics at Yanda.
Ning Chen didn’t know what Qiu Chengtong meant, so he had to continue to wait for Qiu Chengtong’s questions.
"Looking at your information, you are only a freshman, and you are not a mathematics major. How did you get yourself to your current level of mathematics?"
