From University Lecturer to Chief Academician

The postgraduate re-examination of Xihai University has begun.

Every college will attach great importance to the admission of graduate students, because the admission of graduate students is directly related to the source of students for scientific research, and even related to the future development of the school.

Wang Hao's postgraduate enrollment work is even more important, because the students who apply for Wang Hao's postgraduate entrance examination, especially those who enter the re-examination, have extremely amazing scores in the written test.

These students not only have amazing scores in the written test, but also come from famous domestic universities.

Among them, the students applying for the mathematics direction are from Shuimu University, Donggang University, Xijing University of Science and Technology, and Sudong University, not to mention a foreign student who has been confirmed, a gifted student from American Ivy League universities and Stanford University.

It seems that it is not a big deal when it comes to the admissions of the Faculty of Science of Shuimu University and Capital University, but it is different when it comes to the admissions of graduate students of Xihai University.

This is mainly due to the large difference in the source of students in colleges and universities.

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

Most of the colleges and universities that undergraduates choose to study in graduate school will choose colleges and universities that are at the same level as undergraduates or better.

In fact, it is very clear in the job market. Most companies attach 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 of education means differences in intelligence and ability to a certain extent. The college entrance examination is a very fair screening platform. Students who can be admitted to top universities have very valuable grades.

In comparison, graduate students are worse.

Postgraduates can be admitted through hard work, but the proportion of undergraduates in top universities is much smaller.

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

A student who can get the first place in a province is definitely not only achieved by hard work. Even if the other efforts are ten times higher, without enough brain support, it is simply a fantasy to get the first place in the province's college entrance examination.

Not to mention, many of the students admitted to both universities over the years have been contestants.

In the Mathematical Olympiad, it is not possible to win prizes with just training. First of all, you must have enough talent.

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 expert group in advance.

For graduate interviews in the field of mathematics, you must find a professor from the Faculty of Science. Luan Haiping, the dean of the Faculty of Science, and Zhou Qingyuan, a professor of mathematics, naturally entered the interview review team.

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

It is not surprising that Zhu Jianrong joined the interview review team. He often participates in graduate interviews.

Yan Jin was purely interested.

He, a university president, wanted to join the interview team, so naturally no one would object.

This lineup is quite gorgeous.

When Wang Hao saw the interview review list, he couldn't help but muttered, "What interview review team do you want, I can do it myself..."

This sentence is very correct.

No matter what other interview review members have opinions, the final decision-making power is only Wang Hao himself.

...

The postgraduate interview work in mathematics is the first to start.

The interview location was in a small office of the graduate student. When it was almost time for the interview, several students who participated in the re-examination had already arrived.

Among them were two girls and three boys.

Two Donggang University students 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, but because she smiles at everyone, she looks like an outgoing girl.

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

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

A boy next to him, named Xu Jie, nodded and said, "I also regret it a bit. I can't help it even after I have reported it. I have been very nervous these days and have been preparing for a long time."

"What have you prepared?" Hu Lidan asked curiously.

Xu Jie said, "Mersenne prime numbers, Arting's conjecture, and Kakutani's conjecture. I downloaded several papers written by Professor Wang Hao and looked at them one by one. Although most of them were incomprehensible, I still understood the general proof process. "

What Xu Jie said surprised everyone else.

Hu Lidan couldn't help giving a thumbs up, "I thought I was fully prepared, but I didn't expect you to be more fully prepared than me."

"What are you preparing?" Xu Jie asked.

The other three students also looked over.

"I just reviewed the content related to differential equations carefully, and I 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 for graduate school, as long as you study in a As long as there is research in the direction, it is enough. Professor Wang Hao is best at partial differential equations, which is also his original research direction, so I think..."

"Balabara~~"

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

The others immediately felt that it made sense.

Anyone who has studied Wang Hao's results knows that he is good at partial differential equations and number theory, but it is difficult for undergraduates to learn how to study 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, just like her name, feeling a little dazed.

She... was not prepared for anything.

She was the No. 1 student in the college entrance examination in Beijiang Province four years ago, and she applied for Wang Hao's postgraduate examination purely because she felt that she was no worse than Shuimu University's graduate school, and mainly because she was 'close to home'.

Since it is not worse than studying at Mizuki University, and it is closer to home, it naturally feels good.

So she signed up.

Chen Mengmeng didn't make any preparations. She was a genius student since she was a child. She thought that as the top student in the college entrance examination in Beijiang Province and an undergraduate student of Shuimu University, she would have the opportunity to be admitted directly to the postgraduate entrance examination. Among the group of small-town exercisers, he is definitely outstanding.

Is there any difficulty in taking the postgraduate entrance examination?

This was Chen Mengmeng's pure thought, but now listening to other people's talk, she lost her confidence a bit, feeling that she was really too arrogant.

yes!

How can Professor Wang Hao's graduate students be so easy to take the exam? You still need to prepare more for the retest!

...

Amidst the chatting and apprehension of several students, the interview finally officially started.

The first interviewer was Xu Jie from Sudong University. After he entered, he saw five interviewing teachers.

The youngest Wang Hao sat on the side.

The first person to ask was a little old man, "Come and introduce yourself."

This is a normal question.

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

The second question was Zhu Jianrong. He asked several questions in succession, "Are you going to do a Ph.D. after you graduate?"

"Why did you choose to take the postgraduate entrance examination instead of working directly? I think your resume is a graduate of Sudong University, right? And your grades are quite good. It should be easy to find a good job."

"Do you have a definite career plan? For example, after finishing your postgraduate study at Xihai University, will you consider staying in school for a Ph.D., and then continue to engage in research work in the field of mathematics?"

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

The next question was Zhou Qingyuan. Zhou Qingyuan asked a professional question, "Talk about the solution of inhomogeneous partial differential equations. How many methods have you learned? Which equations can be solved?"

This question will test the students' mathematical ability.

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

His grades are still very good, even if he is not prepared, he said something.

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

Luan Haiping's question was straightforward, "Give me a reason for admitting you."

Xu Jie breathed a sigh of relief, and immediately began to speak with confidence. He talked about the mathematics research work he had participated in for four years in college, and expressed his interest in mathematics research, and hoped to devote his life to doing research on the basics of mathematics, etc. .

This answer is still pretty standard.

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

After all, they were competitors, so it was impossible for him to disclose 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 of Donggang University, and he was asked similar questions after he entered.

His performance was not as good as Xu Jie's. He didn't even answer the question of the partial differential equation. After he came out, he was obviously a little disappointed, and his eyes were red when he returned to his position.

Next, Hu Lidan.

Hu Lidan hit the 'knowledge' topic.

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

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

The next one, Qiu Hui'an, was mediocre.

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

Although she is very good among the group of small-town exercisers, because she didn't make much preparation for the re-examination, and she was very nervous when she entered, almost no questions were answered in one go.

After several individual interviews were completed, the interview review team also discussed.

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

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

Zhu Zhenrong admired Xu Jie very much, "Xu Jie from Sudong University is also very good. This student speaks very sincerely and looks very confident."

Yan Jin admires Qiu Huian and Zhang Haijiang who are more mediocre. He believes that such mediocre interviewers will have a future in research and development. Anyway, cheerful personality and fluent interview answers are fundamentally negative for mathematics research. Performance.

Where is a mathematician with a very cheerful personality?

Where are mathematicians 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. They need to do it together."

"ah?"

Unbeknownst to the others, Wang Hao also prepared questions.

Then they saw Wang Hao walking to the door, beckoning the students to come in together, carefully assigning them a few seats, and taking out five test papers from the bag, and handing them out one by one, "This question, for You have half an hour."

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

"If you say it well, it must be a high score for me."

"..."

After hearing Wang Hao's words, several interview judges were very surprised.

Zhou Qingyuan walked over and glanced at the topic, then froze in place, with a strange expression and his mouth opened wide in surprise.

"NS equation?"

Others also glanced over, and immediately looked at Wang Hao with a weird expression, almost meaning, "Are you serious?"

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

They can all be said to be very outstanding among the town's homeworkers. What they are best at is doing the questions, but when they get the test papers, they are immediately confused when they look at the questions above.

"NS equation?"

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

Their faces turned black.

NS equation?

If you can make this kind of question, do you still use it for the postgraduate re-examination here...

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

Chen Mengmeng and Qiu Hui'an had never heard of it.

They knew the Seven Mathematical Conjectures of the Millennium, but didn't know that the NS equation was one of them.

This is actually quite normal.

Some of the seven mathematical conjectures of the millennium are very famous, but some are less known. The NS equation belongs to the latter. The main reason is that it is difficult to understand the NS equation and requires a solid foundation Knowledge can be forgotten at a glance.

Whether they know it or not, when they look at the questions on the test paper, their performance is the same. They don't understand the questions at all.

Although Wang Hao gave a simple explanation above, and tried to explain it in an understandable way, but the content involved in NS is too complicated, and it is absolutely impossible for undergraduates to understand it.

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

Xu Jie, Zhang Haijiang, and Hu Lidan simply gave up. They began to think carefully about what Wang Hao said, thinking about what to say later.

Qiu Hui'an also couldn't understand the questions, but he still tried to use his own knowledge to solve the questions, but the content he wrote was illogical even to him.

Among them, only Chen Mengmeng was really thinking seriously.

Chen Mengmeng was in the same situation as Qiu Huian, she also had only a half-knowledge of the problem, and she also didn't know one of the millennium mathematical conjectures, but she still seriously thought about the direction of solving the problem.

But obviously thinking about the direction of problem solving is also doing useless work.

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

time up!

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

There are no other questions this time, just Wang Hao asking them to talk about the direction of thinking about the topic just now.

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

You also find it very interesting to review the other interviews. Let a few undergraduates explain their opinions and suggestions on the direction of NS...

What can you say?

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

"The NS equation is one of the seven major mathematical conjectures of the millennium. I believe no one has been able to do it until now. Professor Wang Hao, and neither have you."

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 very rich knowledge. The foundation is the most important. In the future, you must learn the basic content well before you can..."

"Wow wow ~~"

He kept saying a lot.

Wang Hao was a little confused, why did this student teach me?

A few others felt that what Xu Jie said was right, that only by laying a good foundation can we do research. 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 was almost the same as Xu Jie's, except that she said a direction, "I think it is impossible to solve this problem by using the knowledge in the field of differential equations alone. Algebraic geometry and Riemannian geometry should also be involved."

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

Hu Lidan blushed, "I just heard about it."

After Hu Lidan said a few more words, she went out to change.

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

Finally it was Chen Mengmeng's turn.

When Chen Mengmeng was working on the questions, she had been thinking about it all the time, but she couldn't think of anything, and she was very nervous when she walked in the door.

Standing in front of Wang Hao, she held back for a long time without saying a word, and it took a long time before she said, "I think..."

"This... this..."

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

"I thought about it just now. I should start with the simple ones and learn. After I get familiar with the simple problems, I can then consider this difficult problem, so that I can learn to solve it."

When Chen Mengmeng opened her mouth, she 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 mathematical conjectures of the millennium.

Several other judges shook their heads immediately.

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

[Task 1, inspiration value +1! 】

very good!

He looked at Chen Mengmeng with great satisfaction, nodded and said, "I've accepted this student, and you can decide the rest."

"??"

The other four interview judges were all stunned. In their opinion, Chen Mengmeng was the worst performer. Why was he admitted directly?

What is this evaluation standard? !
