This time Qiu Sai attracted a lot of attention, especially with Qin Ke and Ning Qingyun participating, and their performance in the semi-finals was so outstanding. The media naturally caught wind of it, and Qingmu University also wanted to expand the influence of Qiu Sai.

As long as formal academic media apply, they will generally be granted access to interviews.

Of course, in order to prevent reporters from disturbing the candidates, the media are not allowed to enter the examination room and can only conduct interviews outside the examination room.

Qin Ke and Ning Qingyun walked hand in hand to the examination room for more than a hundred meters when they saw an examinee being stopped by a reporter from a distance.

Looking inside the examination room, I saw that many candidates from other places had entered the exam room in advance, and the place was bustling inside and outside the examination room.

Qin Ke didn't want to be pestered by reporters, so he turned to Ning Qingyun and smiled: "Would you like to do a 100-meter sprint?"

"Huh?" Ning Qingyun followed Qin Ke's gaze and understood what he meant. She nodded and said, "Okay."

"Don't worry, I'm holding you, you won't fall.123, run!"

Qin pulled the girl with twin ponytails and rushed over like a gust of wind.

Their long twin ponytails fluttered in the wind, and before the reporters could react, the two of them rushed into the examination room.

Ning Qingyun's breath was a little short of breath after running, and her porcelain-white face also had some blush after exercise. The sudden appearance of the two people also attracted the attention of the candidates. Those who knew Qin Ke and Ning Qingyun said hello one after another.

, those who didn’t know him cast curious glances.

Three teammates, Jiang Zhenjie, Ximen Hui and Gan Zhihang, have also arrived. Gan Zhihang looks a little embarrassed, it is obvious that his written test score was actually lower than that of four freshman teammates, and he can't lose face.

Qin Ke went over and said a few polite words to ease the atmosphere, and then they entered the examination waiting room together.

After entering the examination waiting room, everyone no longer paid attention to Qin Ke and Ning Qingyun, and each took out their preparation materials to review.

Qin Ke had nothing to do, so he whispered to a few teammates about some unpopular details that they might ask about. Gan Zhihang was too embarrassed to approach at first, but when Jiang Zhenjie and others nodded, he finally left.

Come here, and once you hear it, you won’t be able to move away.

About half an hour later, it was Qin Ke's turn. Qin Ke smiled at Ning Qingyun and others, got up and followed the staff through the long corridor and entered the examination room.

The examination room is an ordinary classroom with a podium, desks and blackboard. It is not large and can accommodate at most fifty or sixty people.

The staff signaled Qin Ke to stand on the podium and wait for questions, and then closed the door of the examination room to isolate the inside and outside.

The five judges were sitting on the desks on the stage, with name tags in front of them.

Qin Ke recognized Mr. Qiu sitting in the middle at a glance. In addition, looking at the name tags, there were also Professor Nie Yongwen from the Institute of Mathematics of the Xia Academy of Sciences, Professor Dave Bannings from Harvard University, and Professor Nie Yongwen from the Institute of Mathematics of the Chinese Academy of Sciences.

Professor Ariel Sellers of Stanford University and Professor Carmen Peda of Stanford University.

Although Qin Ke has never heard of it, to be invited by Mr. Qiu to be a judge, he is probably a big shot in the industry.

"Hello fellow judges, I am Qin Ke from Qingmu University."

After hearing Qin Ke's name, several judges except Mr. Qiu were obviously surprised, especially Professor Nie Yongwen, who looked at Qin Ke with strange eyes, obviously knowing that Qin Ke was with Professor Duan a few days ago.

Performance in the laboratory.

Professor Carmen Peda of Stanford University asked: "Are you Qin Ke who created the 'fourth-order transformation method of lime number theory' and proved the twin prime number conjecture and other difficult problems?"

Qin Ke said modestly: "It's just a small achievement, the teachers are laughing at it."

Mr. Qiu nodded seriously to Qin Ke and said to the judges in English: "Let the interview begin."

Professor Dave Bannings of Harvard University first said: "Qin Ke, I have read the paper you wrote. You should be very familiar with complex variable functions. I won't ask if it is too simple. You can prove it first.

All Cauchy sequences above converge to one element of the complex field."

Other undergraduates would have been confused, because this was already a Ph.D.-level knowledge point, but Qin Ke breathed a sigh of relief. Fortunately, they were asking serious questions. Qin Ke was afraid that they would ask some tricky questions.

.

Qin Ke asked: "Teachers, do you need to write it down? Or can you answer it directly orally?"

"Can you answer directly?" Professor Ariel Sellers of the University of California, Berkeley, asked unexpectedly.

Qin Ke nodded.

Professor Nie Yongwen said directly: "Then answer orally." As he spoke, he stared at Qin Ke with a keen eye, obviously wanting to see if he was as "god" as the legend said.

Qin Ke hardly needed to think and answered immediately: "The question is actually to prove that the complex number field satisfies the Cauchy convergence criterion, that is, for any given positive number e, there is always a positive integer N, such that when n>N, m

>N, there is |xn-xm| less than e..."

In less than two minutes, Qin Ke had finished dictating.

All the professors present were impressed. He was indeed an internationally renowned mathematical genius. He didn't even use pen and paper and easily answered a difficult question that would stump many doctoral students!

The key is to prove that the thinking is clear, the logic is tight, and there are no flaws!

Professor Nie Yongwen couldn't help but smile: "Okay, originally I was responsible for asking questions about number theory, but your attainments in number theory are better than mine, so I won't show my shame and just ask a question about mathematical physics.

, you are the only one who got full marks in this subject. Well, I won’t embarrass you anymore, just use mathematics to deduce Ampere’s loop law.”

The so-called Ampere's loop law means that in a magnetic field, the line integral of the magnetic induction intensity B along any closed loop L is equal to μ0 times the algebraic sum of all currents I passing through the loop, expressed in a mathematical equation as ∮LB·0∑

Ienc.

This is also a difficult question for doctoral students.

But in Qin Ke's eyes, there was no difficulty either. He easily answered the proof process orally.

Professor Nie Yongwen looked at him for a long time before sighing: "I really believe what you said a few days ago. Okay, this is the top three questions. I will give you full marks for number theory and physics and mathematics."

."

This chapter is not over yet, please click on the next page to continue reading! The other two professors also asked two difficult questions, which were also easily solved by Qin Ke.

Finally, Mr. Qiu spoke: "Qin Ke, they asked few questions. It's too easy for you to get full marks. I'll just ask three questions."

Qin Ke woke up and said respectfully: "Mr. Qiu, please tell me."

Mr. Qiu asked slowly in English: "You have been to Princeton University before, so you should have some understanding of the situation of the students there. What do you think is the difference in mathematics learning between them and Xiaguo students?"

Qin Ke was stunned. Mr. Qiu's question...does it have anything to do with Qiu Sai?

But since Mr. Qiu asked the question, Qin Ke could not help but answer.

He thought for a long time and then said thoughtfully: "The first impression I have of the students at Princeton University is that they are arrogant. Of course, they have the capital of arrogance. Their level of mathematics is indeed very high and their thinking is very flexible.

The strength of our country's students lies in their diligence and studiousness. Recently, there is a buzzword called 'Become a problem solver in a small town', which basically shows the learning style of our country's students."

"In addition, Chinese students are not as interested in mathematics as U.S. students. Xia Guo students study mathematics more for utilitarian purposes rather than interest or love for mathematics. But most students in U.S. universities are really interested in mathematics.

.The communication themes in their leisure and social activities often revolve around mathematical themes.”

"When I gave a lecture at the University of Pennsylvania, almost all the students from the Department of Mathematics at the University of Pennsylvania were present. Even if they had to stand the whole time because there were no seats and it was uncomfortable to be crowded, none of them left early. I also noticed that there was no one there the whole time.

Playing on mobile phones, not whispering, just listening attentively, and many people are taking notes."

"I dare not say how good my report is, but I know that the students at Pudong University looked down on the Xia Guo students at the beginning and were quite repelled by my report. But when they found out that they listened to my report

When you see the value, you can put aside your prejudices and come to listen carefully. This also includes professors and lecturers from Pudong University. This should be the culture of Pudong University that is tireless in studying."

"On the contrary, I have attended many lectures in China, including lectures on mathematics. Basically, the seats can barely be filled, with very few people standing to listen. There are also many people playing with their mobile phones and chatting during the whole process."

"To sum up, Chinese students are better at being able to calm down to study difficult problems and implement problem-solving strategies. Their foundations will be stronger than those of ordinary university students, but they will be inferior in terms of innovation and creativity. For the purity of mathematics,

My interest is not as good as that of ordinary university students."

Mr. Qiu nodded approvingly and asked: "How do you think Xia Guo should promote mathematics education to improve the overall mathematics level?"

Qin Ke scratched his head. Is this too big a question? "Mr. Qiu, your question is a bit too difficult. It is really beyond the ability of a mere freshman like me to answer. I can only give my own opinions."

Mr. Qiu waved his hand: "It's okay, I just want to hear your personal opinions."

Qin Ke thought for a while before speaking: "I think that improving Xia Guo's mathematics level cannot be achieved overnight. There are many historical reasons, as well as economic and educational resource reasons. But the first step should be

Cultivate students' interest in mathematics and make basic mathematics education as grounded as possible so that students can apply what they have learned to solve problems encountered in life."

"For example, Ning and I worked together to compile supplementary mathematics teaching materials for junior high and high schools, and we started from these two aspects. Using storylines to enhance the attractiveness of mathematics, and using storylines to inspire how to apply the mathematical knowledge in junior high and high schools.

"

"As for mathematics in college, I think it is right to pursue elite education. Mathematics is a subject that requires talent. Those who don't like it or are not very talented will basically not be able to enter the mathematics major. Except for a few students who have been transferred to majors. They are only elites.

Education depends too much on educational resources, teachers’ sense of responsibility and academic level.”

"All the professors at PKU are responsible for teaching, even the head of the mathematics department. Therefore, PKU teaches in small classes. On average, one professor teaches five or six students, and he can teach each student in accordance with his or her aptitude. The universities here are basically

Above, a professor faces dozens or even hundreds of students at the same time. At the end of a semester, except for a few students who are outstanding, active, and love to ask questions, the professor doesn’t even remember the names of most of the students. From this point of view,

, not even as good as a high school math teacher.”

"In addition, there is the issue of academic style, such as eagerness for quick gains and not being able to concentrate on learning. Teachers and students all have reasons for this. Of course, as a student, it is inconvenient for me to evaluate senior professors. Please forgive me in this regard, Mr. Qiu."

"I think your concept, Mr. Qiu, is quite good. Whether it is the previous elite class or the current Qiuzhen Academy, they are the seeds for cultivating high-end mathematics talents in terms of faculty strength, sense of responsibility and study style. When these seeds are broadcast,

If we go and teach knowledge in the same way, we can probably use points to drive lines and then surfaces, improving the overall level of Xia Guo's mathematics."

"The above is my humble opinion. Please comment on it, Mr. Qiu." Qin Ke bowed slightly as he spoke.

"You little naughty boy, you just brushed off the key issues and flattered me. But..." Mr. Qiu looked at Qin Ke for a while and finally smiled: "You and Ning Qingyun compiled the teachings

The supplementary materials are indeed very good, and are very helpful in promoting basic knowledge of mathematics. Your analysis of the differences between students from PCU and Xia Guo is also quite accurate. I count you passing. Finally, I want to ask you a question."

"You asked."

"I know you will graduate with a bachelor's degree in your sophomore year. Are you interested in teaching at Qiuzhen Academy?"
