The re-examination of graduate students at Seohai University began.

Every university attaches great importance to the admission of graduate students, because the admission of graduate students is directly related to the source of scientific research students, and even related to the future development of the university.

Wang Hao's graduate student enrollment work is the top priority, because the students who apply for Wang Hao's graduate students, especially those who enter the re-examination, have extremely amazing written test results.

These students not only have amazing results in written exams, but they are also from prestigious universities in China.

Among them, the students who applied for the mathematics direction are from Shuimu University, Donggang University, Xijing University of Science and Technology, and Sudong University, not to mention the already determined foreign students, talented students from Amriken Ivy League universities and Stanford University.

On the enrollment of the Faculty of Science of Shuimu University and Capital University, it seems that it is not a big deal, but it is different when it is placed on the graduate enrollment of Xihai University.

This is mainly due to the fact that there is too much difference in the source of college students.

Even if Xihai University recruits lecturers, it is difficult to recruit doctoral students from top universities such as Mizuki University and Capital University, and it is even more difficult to recruit undergraduates from top universities than to hire PhDs from top universities.

Most of the colleges and universities that undergraduates choose to study in graduate school will choose universities that are at the same level or better than their undergraduates, otherwise it seems that it is not meaningful for graduate students to study.

In fact, it is very clear in the job market, the general company attaches great importance to the first degree, and undergraduates from top universities are even more popular than graduate students from ordinary universities.

This is mainly because, many people believe that the first degree means the difference in wisdom and ability to a certain extent, and the college entrance examination is a very fair screening platform, and students who can be admitted to top universities have very valuable results.

Comparatively, graduate students are a bit worse.

Graduate students can be admitted through hard work, while the proportion of undergraduates in top universities is much smaller.

For example, Mizuki University and Capital University admit many provincial champions every year.

Students who can get the first place in a province are definitely not only hard work, even if they work ten times harder, without enough mental support, it is simply impossible to get the top prize in the college entrance examination in the province.

Not to mention, over the past many years, many of the students admitted to the two universities have been competitive students.

The Mathematics Olympiad is not a prize that can be won by training, first of all, you must have enough talent.

In scientific research, talent is very important.

In many high-tech jobs, talent is more important than hard work.

Xihai University attaches great importance to Wang Hao's recruitment of graduate students, and they have organized an interview panel in advance.

For the interview of graduate students in mathematics, they must find professors from the Faculty of Science, Dean Luan Haiping of the Faculty of Science, and Professor Zhou Qingyuan of Mathematics, so they naturally entered the interview and evaluation team.

Two others joined, including Zhu Jianrong, director of the Science and Technology Office, and Yan Jin, president of Xihai University.

It is not surprising that Zhu Jianrong joined the interview review team, and he often participates in the interview work of graduate students.

Yan Jin is purely interested.

He is a university president who wants to join the interview team, so naturally no one will object.

This lineup is quite gorgeous.

Wang Hao saw the interview review list and pulled the corners of his mouth, and muttered, "What interview review team you want, I'll just come by myself......"

This statement is quite true.

No matter what the other interview review members think, the final decision is only Wang Hao himself.

……

Graduate interviews in mathematics begin first.

The interview took place in a small office of the graduate student, and when it was almost time for the interview, several students who had taken the re-examination had already arrived.

There were two girls and three boys.

Two students from Eastport University sat together, and the others sat alone without speaking.

There is a girl with braids who is very eye-catching, not because she is beautiful or anything like that, but she will smile at everyone, and she looks like an outgoing girl.

Her name is Hu Lidan and she is from Xijing University of Science and Technology.

When he found that everyone didn't speak, Hu Lidan first asked, "Are you all prepared for the interview?" I don't know what will happen to Professor Wang's interview, but I regret it now, and I can get into Mizuki University with this score. ”

There was a boy next to him, his name was Xu Jie, he nodded and said, "I also regret it a little." I can't help it, I've been very nervous these days, and I've been preparing for a long time. ”

"What are you preparing?" Hu Lidan asked curiously.

Xu Jie said, "The Mason prime, the Atin conjecture and the Kakutani conjecture. I downloaded a few papers by Professor Wang Hao and looked at them one by one, although most of them I couldn't understand, but I still figured out the general proof process. ”

Xu Jie's preparation surprised everyone else.

Hu Lidan couldn't help but give a thumbs up, "I thought I was well prepared, but I didn't expect you to be even more adequate than me." ”

"What are you going to do?" Xu Jie asked.

The other three students also looked over.

"I just carefully reviewed the content related to differential equations, and also looked at the content of differential equations at the graduate level." Hu Lidan explained, "I don't know what questions Professor Wang Hao will ask, but I think that when you go to graduate school, as long as you have research in one direction, you can do it. Professor Wang Hao is best at partial differential equations, which is also his original research direction, so I think ......"

"Balabala~~"

Hu Lidan said a lot in a row, which almost meant that Professor Wang Hao was likely to ask about the content of partial differential equations.

The others immediately felt that it made sense.

As long as those who have studied Wang Hao's work know that he is good at partial differential equations and number theory, but it is difficult for undergraduates to get in touch with how to study the content of number theory.

Then it may be very important to review the content related to differential equations.

Chen Mengmeng sat in the corner, listening to the conversation between the two people, just like her name, feeling a little confused.

She...... Didn't prepare anything.

She was the top student in the college entrance examination in Northern Xinjiang Province four years ago, and she applied for Wang Hao's graduate school purely because she felt no worse than her graduate studies at Mizuki University, and it was mainly 'close to home'.

Since it's no worse than Mizuki University's graduate school, and it's closer to home, it naturally feels good.

So she signed up.

Chen Mengmeng didn't make any preparations, she has been a genius since she was a child, thinking that as the former champion of the college entrance examination in Northern Xinjiang Province, an undergraduate student of Shuimu University, she has the opportunity to be directly guaranteed to be researched, even if she is admitted to graduate school, she can be among the best, and she is definitely outstanding in the group of small town practitioners.

Can there be any difficulty in the graduate school entrance examination?

This is Chen Mengmeng's simple thoughts, but now listening to other people's talks, she has lost confidence a little, and feels that she is indeed too arrogant.

That's right!

How can Professor Wang Hao's graduate students be so easy to get into? You still have to prepare more for the retest!

……

Amid the small talk and apprehension of several students, the interview finally began in earnest.

The first interview was Xu Jie from Sudong University, and after he entered, he saw five interview teachers.

The youngest Wang Hao sat on the side.

The first person to ask a question was a little old man, "Tell me about yourself." ”

This is a normal question.

Xu Jie was well prepared for the interview, and he immediately said what he had prepared, and also talked about his scientific research practice experience in the university.

The second question was asked by Zhu Jianrong, who asked several questions in a row, "Are you going to study for a doctorate after you go to graduate school?" ”

"Why did you choose to go to graduate school instead of working directly, I see that your resume is a graduate of Sudong University, right? And the grades are quite good, and it should be easy to find a good job. ”

"Is there a definite career plan? For example, after completing graduate studies at Isohai University, will you consider staying at the university to study for a Ph.D. and then continue to engage in research in the field of mathematics? ”

Zhu Jianrong asked several questions in a row, all of which were expected.

The next question was asked by Zhou Qingyuan, who asked a professional question, "Talking about the problem of solving non-homogeneous partial differential equations, how many methods have you learned?" What equations can be solved? ”

This question is a test of students' math skills.

Xu Jie was suddenly a little nervous, and at the same time admired Hu Lidan very much, there was really a professional question about partial differential equations, but it was not Wang Hao who asked it, but an unknown old professor.

His grades were still very good, and even if he wasn't prepared, he said something.

After Xu Jie finished speaking, Zhou Qingyuan didn't know whether he was satisfied or dissatisfied, but nodded lightly.

Luan Haiping's question was very straightforward, "Give me a reason to admit you." ”

Xu Jie exhaled lightly, and immediately said with confidence, talking about the mathematical research work he had participated in in four years of college, and expressed his interest in mathematical research, and hoped to devote his life to the research of mathematical foundations, and so on.

This answer is still very standard.

After Luan Haiping asked questions, he didn't ask any more questions, Xu Jie walked out of the door with doubts, but he didn't tell anyone else, just sat back silently.

After all, they were competitors to each other, and it was impossible for him to reveal the problem in advance, but he still gave Hu Lidan a thumbs up.

It was just a small movement, and only Hu Lidan noticed it, but she still understood what Xu Jie meant, and a confident smile suddenly appeared on her face.

Next, Zhang Haijiang.

Zhang Haijiang is a student at Donggang University, and after he went in, he was asked similar questions.

His performance was a little inferior to Xu Jie, and he didn't even answer the questions about the partial differential equations, and he was obviously a little lost after coming out, and his eyes were red after he returned to his position.

Next, Hu Lidan.

Hu Lidan hit the question of 'knowledge'.

Zhou Qingyuan's research and development field is partial differential equations, and the questions he asks each student are different, but they are still problems in the field of partial equations, and they are not beyond the level of undergraduates.

Other people's questions are open-ended, and it's hard to say whether it's good or bad.

The next one, Qiu Hoi An, is very mediocre.

The next one is Chen Mengmeng, and her performance can be said to be the worst.

Although she is very good in the group of small-town problem solvers, because she did not prepare much for the retest, and she was very nervous when she entered, there were almost no questions to answer in one go.

After the individual interviews of several people are over, the interview review team also discusses.

Zhou Qingyuan said, "I think the first few are very good, especially that Hu Lidan, who is very good, and obviously the opposite side is very well prepared, although her university is a little poor......"

Xijing University of Science and Technology is not a bad school, but it is indeed a lot worse than the schools that other people graduated from.

Zhu Zhenrong admired Xu Jie very much, "Xu Jie of Sudong University is also very good, this student speaks very sincerely, and he looks confident." ”

Yan Jin admires the 'mediocre' Qiu Hui'an and Zhang Haijiang more, and he thinks that this kind of mediocre interview person will have a future in research and development.

Where is a mathematician who is very cheerful?

Where is there a mathematician who is very good at talking?

In the end, everyone else looked at Wang Hao, and Wang Hao said, "The interview is not over yet, I have a question here, and they have to do it together." ”

"Huh?"

Others didn't know that Wang Hao also prepared a question.

Then they saw Wang Hao walk to the door, beckoned the students to come in together, assigned them a few seats very seriously, and took out five test papers from their bags and distributed them one by one, "This question, give you half an hour." ”

"Whether you can do it or not is secondary, and even whether you can understand it or not is secondary, but I hope you can say a direction to solve the problem."

"If it's good, it's definitely a high score for me."

“……”

Several interview judges were very surprised when they heard Wang Hao's words.

Zhou Qingyuan walked over and glanced at the question, and he was directly stunned in place, with a strange expression and a wide open mouth in surprise.

"NS equation?"

The others also glanced over and immediately looked at Wang Hao with a strange expression, which almost meant, "Are you serious?" ”

Several students got the test papers and were eager to take the test.

They can all be said to be very outstanding in the small town exercises, and what they are best at is doing questions, but after getting the test papers, they are directly blinded when they look at the questions above.

"NS equation?"

Xu Jie, Zhang Haijiang, and Hu Lidan have all heard the NS equation and know that this problem is one of the seven major mathematical conjectures of the millennium, so they know that they will definitely not be able to do it.

Their faces were darkened.

NS equation?

If you can make this kind of question, can you still use it here for the graduate retest......

They all felt like they were dreaming, and Xu Jie pinched his face hard, as if to verify that he was not dreaming.

Chen Mengmeng and Qiu Huian had never heard of it at all.

They know the seven millennial mathematical conjectures, but they don't know that the NS equation is one of them.

This is actually quite normal.

The seven major mathematical conjectures of the millennium, some of which are very famous, but some of which are little known, the NS equation belongs to the latter, the main reason is that it is difficult to understand the NS equation, and it needs to have sufficient basic knowledge, and you may forget it at a glance.

Whether they know it or not, they look at the questions on the test paper, and the performance is the same, they can't understand the questions at all.

Although Wang Hao made a simple explanation above and tried to explain it in a way that he could understand, the content involved in NS was too complex and could never be understood by undergraduates.

Even the question can only be roughly known, and it is impossible to answer it at all.

Xu Jie, Zhang Haijiang, and Hu Lidan simply gave up directly, and they began to think carefully about what Wang Hao said, thinking about what to say for a while.

Qiu Hui'an also couldn't understand the questions, but he still tried to use his own knowledge to do the questions, but the content he wrote didn't even feel logical.

Among them, only Chen Mengmeng is really thinking seriously.

Chen Mengmeng, like Qiu Hui'an, also knows little about the problem, and she also doesn't know one of the millennial mathematical conjectures, but she still seriously thinks about the direction of the solution.

But obviously, trying to figure out the direction of the problem is also useless.

Chen Mengmeng was stunned and thought, and when the time was almost over, she didn't think of anything.

It's time!

Wang Hao asked everyone to put down the pen in their hands, and then let them all go out, and then come in again one by one for the interview.

There are no other questions this time, it's just that Wang Hao asked them to talk about the direction of thinking about the topic just now.

By this time, the students have realized that the real interview starts now.

You also found it interesting to ask a few undergraduates to explain their views and suggestions on the NS direction......

What can be said?

The first one to come in was still Xu Jie, who had already figured out how to answer, "I was working on the question very seriously just now, but this question, I feel that it is completely beyond my ability." ”

"The NS equation is one of the seven major mathematical conjectures of the millennium, and I believe that no one has been able to do it until now, Professor Wang Hao, you don't have it."

Wang Hao nodded, "I'm preparing to do this research." ”

Xu Jie continued, "I think that if you want to solve this problem, you must have a very rich knowledge, and the foundation is the most important, and in the future, you must learn the basic content well in order to ......."

"Wow, wow~~"

He said a lot in a row.

Wang Hao was a little stunned when he heard it, why did this student still educate me?

A few other people think that what Xu Jie said is very right, only by laying a good foundation can you do research, and it is really good to have this awareness!

Finally after Xu Jie finished speaking, Wang Hao hurriedly let the next person in.

Hu Lidan.

Hu Lidan's answer is almost the same as Xu Jie's, the difference is that she said in one direction, "I think that the knowledge in the field of differential equations alone cannot solve this problem, and it should also involve algebraic geometry and Riemannian geometry." ”

"Do you know Riemannian geometry?" Zhou Qingyuan asked with some surprise.

Hu Lidan's face turned red, "I've just heard of it." ”

After Hu Lidan said a few more words, he went out to replace the next one.

The next Qiu Hui'an and Zhang Haijiang just said a few words according to their own understanding, but at least they didn't say clichés, which made Wang Hao's senses slightly better.

In the end, it was Chen Mengmeng's turn.

When Chen Mengmeng was doing the question, she had been thinking about it, but she didn't think of anything and was very nervous when she walked in the door.

She stood in front of Wang Hao, held back for a long time without speaking, and only said a sentence for a long time, "I think it......"

"This ...... This ......"

"I'm really sorry, Mr. Wang Hao, my knowledge level is not enough, and it is impossible to make this topic."

"I just thought about it, I should start with the simple ones, learn them, and wait until I am familiar with the simple problems, and then think about this difficult problem, so that I can learn to solve it."

Chen Mengmeng's opening let others know that she didn't know the NS equation at all, and of course she didn't know that the NS equation was one of the seven major mathematical conjectures of the millennium.

Several of the other judges shook their heads.

Wang Hao's eyes lit up, because he received a system prompt-

[Task 1, Inspiration +1!] 】

Very good!

He looked at Chen Mengmeng with great satisfaction, nodded and said, "This student, I have been admitted, and you can decide the rest." ”

“？？”

The other four interview judges were stunned, in their opinion, Chen Mengmeng was the worst performer, why was she admitted directly?

What is the evaluation criterion?!
