From University Lecturer to Chief Academician

Wang Hao's evaluation criteria are very straightforward, and students who can bring inspiration are good students.

For tasks with S+ difficulty levels, the difficulty of increasing the inspiration value has risen to a higher level than that of S-level difficulty. Every point of increase in inspiration value can be said to be very precious.

If there is a student who can bring a little inspiration, even if it is done by luck, he will definitely admit it directly.

There is no need to think about other aspects at all, because the students who can take the re-examination are all very top-notch in terms of grades, and basically there will be no problems.

Whether it is suitable for research and development in the future can not be seen in a single interview.

Unless there is that kind of very good genius, the undergraduate level can make certain achievements, and then you can see something.

This kind of genius is obviously phoenix.

The deeper Wang Hao studies mathematics, the more he feels the importance of inspiration. Knowledge can be obtained through learning, but inspiration, or the correct ideas for R\u0026D and problem solving, cannot be obtained through learning.

Chen Mengmeng's interview performance was worse than others, but it was not bad after thinking about it. She answered the partial differential equation question raised by Zhou Qingyuan. As for the other questions, they were completely meaningless, and everyone's evaluation was different.

"What would happen if Schultz came to this interview?"

After thinking about it carefully, Wang Hao knows that the interview result is likely to fail. Maybe Schultz will make a lot of ridicule to several interviewers.

Mathematics research, is it enough to be able to speak?

For Wang Hao, the most important thing is that Chen Mengmeng explained the direction of 'solving the problem' according to his own ideas. She said to get familiar with simple problems first, and then consider more difficult problems, in order to solve the problems.

This sentence seems meaningless, but it brought inspiration to Wang Hao.

The NS equation is a nonlinear partial differential equation problem, and it is very difficult and complicated to solve it. Before the solution ideas and technologies are further developed and breakthroughs, only certain very simple special cases of flow problems can be solved accurately. In some The case can be simplified to obtain an approximate solution.

So if you want to solve the equation problem, the first thing to do is to clarify and understand the simple and solvable problems.

The system fed back relevant information, indicating that this is the correct way of thinking.

...

Wang Hao left after making a decision. As for the other students, just let the interview review team decide.

The final admissions were Chen Mengmeng, Qiu Huian and Xu Jie.

The decision made by the interview review team is not based on a single interview, but a judgment made based on the results of the interview and the written test.

Qiu Hui'an's interview performance was slightly worse, but his written test score was second, only a little behind Chen Mengmeng; Xu Jie's interview performance was very good, and with his mid-level written test scores, his overall score ranked third, also was admitted.

After confirming the list of admitted students, the interview review team specially found the detailed information of three students, put them together for comparison, and found that there was no problem in admitting Chen Mengmeng, and the resume was indeed the best.

Chen Mengmeng is the number one student in the college entrance examination in Northern Xinjiang Province, and her grades in Shuimu University have always been among the top. She doesn't need to take the postgraduate exam at all, and can be directly recommended to study in this school, but she still took the exam for some reason.

Qiu Hui'an is a student of Donggang University. His grades are relatively mediocre. He failed to obtain the postgraduate qualifications, but his postgraduate written test scores are very good.

Among the three, Xu Jie is relatively inferior. Sudong University is also a top university in China, but there is always a difference between the top and the top. Compared with Shuimu University and Donggang University, Sudong University is still worse. In addition, Xu Jie's written test scores There are also pull points, and the interview performance is very good, so I was barely admitted.

The other two, Hu Lidan and Zhang Haijiang, are really a pity.

Although Hu Lidan's interview performance was not bad, her written test score was also the worst. Zhang Haijiang's comprehensive score was only a little lower than Xu Jie's, and she unfortunately failed the selection.

Xihai University also attaches great importance to the unselected students. Compared with the level of graduate students recruited by other master and doctoral supervisors in the Faculty of Science, Hu Lidan and Zhang Haijiang are undoubtedly much better.

Several master and doctoral supervisors directly came forward to persuade them to stay in Xihai University.

In the end, only Hu Lidan stayed, and she decided to follow Zheng Yaojun to study in graduate school, and engaged in the study and research of partial differential equations.

...

Wang Hao's postgraduate re-examination was over, and the time between the announcement of the list of admitted students was very fast, and the interval was only two days.

Chen Mengmeng knew it at the time.

After the interview, she left with a dazed mind, thinking all the way why she passed, but she still couldn't figure it out at all.

After returning home, she told her parents that she was admitted, and then she checked the questions during the interview, and immediately found the relevant information——

NS equation.

One of the seven mathematical conjectures of the millennium?

When Chen Mengmeng saw the content on the webpage, doubts and confusion were written all over her face.

She has always been very confident in her mathematics level, and her grades and scores in all mathematics subjects are all above grade A, but after going to the interview, she felt that she had suffered a big blow, and she couldn't even understand the questions.

Now, confidence seems to be back.

One of the seven mathematical conjectures?

"No wonder!" Chen Mengmeng rubbed her eyes vigorously, "It turned out to be a mathematical conjecture, and it's a very complicated one, so it's no wonder I couldn't understand it."

"Why did Professor Wang use this as a topic?"

She thought for a long time and still couldn't figure it out.

When Chen Mengmeng was in surprise, several other students who participated in the re-examination were also surprised.

"You will never guess what questions I did in the re-examination." Xu Jie said confidently in the group of classmates.

"Didn't you enroll Professor Wang Hao as a graduate student? Could he still ask you questions about number theory?" A classmate replied by typing.

"It's a partial differential equation." Xu Jie reminded.

"It turned out to be a partial differential equation. It's not surprising. I studied it carefully. Wang Hao's initial research direction was partial differential equations." Those students immediately analyzed it.

Xu Jie said, "It is indeed a partial differential equation. My topic is to prove the existence of a smooth bound for a class of nonlinear partial differential equations."

As soon as these words were said, the group of classmates immediately exploded.

"It's very difficult!"

"How can this be!"

"This kind of question, I think it should be the research content of a doctor or a professor, right? Even the simplest one, it is impossible to appear in the postgraduate re-examination questions."

Xu Jie continued, "Why are you so anxious? I haven't finished talking yet. You must have heard of this type of partial differential equation. It's called Navier-Stokes. How about it? Do you feel familiar?"

"..."

"..."

A bunch of ellipsis appeared in the group, and finally a person typed and asked, "Did you make it?"

The following ellipsis becomes more.

...

After the admission of graduate students in the direction of mathematics is over, the re-examination for graduate students in the direction of informatics has also begun.

This time Wang Hao did not ask the students any more questions, but asked a few questions about codes and algorithms on the spot.

Compared with the high requirements for the direction of mathematics, Wang Hao believes that the direction of informatics is more important than the level of personal knowledge and ability. Of course, it is the best to have more mathematics as a foundation.

Wang Hao does not have high requirements for informatics students, most of them are mediocre, and the possibility of expecting students to win any international awards in the future is really too low.

In this regard luck is more important than screening students.

On the contrary, the professors of the School of Computer Science were very concerned about Wang Hao's recruitment of graduate students. The old man Chen Qinghua asked with interest, "What do you expect from the students?"

Wang Hao thought about it carefully, and said hesitantly, "It's fine if it's not worse than Zhang Zhiqiang."

Chen Qinghua thought about it carefully, and made a small comment, "Actually, Zhang Zhiqiang's level..."

He drew a long voice, and finally said, "He worked very hard."

...

a week later.

He Yi and Xiao Xinyu from the Physics Department flew to the capital with Wang Hao.

Xiao Xinyu is another professor in the Department of Physics. He has a lot of research on superconducting materials, especially high-temperature superconductivity, but obviously superconductivity has nothing to do with high-energy physics. He just came here to gather the number of people.

Along the way, Wang Hao chatted more with Xiao Xinyu.

Xiao Xinyu talked about the latest research on superconductivity, which is directly related to the very attractive "anti-gravity". "No scientist dared to say that he was studying anti-gravity before."

"Stanford spends $100 million a year on this research, and it's hardly producing anything."

"Some time ago, a physicist from American used experiments to prove that a superconducting disk rotating at a high speed in an experimental environment close to absolute zero can cause mass loss of some objects within a fixed magnetic field."

"The experiment has determined that the mass loss is about 1%. The data is very small, but it is definitely a huge breakthrough discovery."

Xiao Xinyu concluded, "This is an academic success in producing anti-gravity in an experimental environment."

The study of antigravity is undoubtedly very fascinating.

Flying cars appearing in sci-fi movies can float directly in place, which seems to use anti-gravity technology.

And if you want to make that kind of car, only anti-gravity technology can realize it.

It’s just that this kind of technology still belongs to the “future technology”. Even in the experimental environment, the academic success of anti-gravity has been achieved, but human beings have not discovered any specific phenomena from the universe to prove the existence of anti-gravity.

Some people think that the universe has only positive gravitational force, and it is impossible to have negative mass repulsive force.

Wang Hao and Xiao Xinyu felt very interesting along the way.

He Yi seemed a little 'unwilling to be lonely', and also talked about the spectrometer detection experiment meeting, "This research is very important and can be used to discover the asymmetry of particle decay."

"The main purpose of this research is to find evidence for the asymmetry of positive and negative matter."

"The previous spectrometer detection experiments have been able to measure the asymmetry parameters of the positive and negative Cauchy hyperons, and the accuracy can reach hundreds of billions of levels, which has verified the standard model of particles."

"This time we are going to participate in a larger experiment. It is said that we will eventually conduct detailed data analysis on tens of billions of J/psi particles. It is expected that the measurement accuracy will increase by more than three times."

After He Yi finished speaking, he waited for the two to ask questions.

As a result, Wang Hao and Xiao Xinyu just listened, and then continued to talk about the "anti-gravity" issue. Obviously, compared with the anti-gravity of black technology, the measurement of the standard model of particles and the measurement of the asymmetry of tiny particles, the attractiveness is really poor. too much.

Of course, the purpose of their coming to the capital is to participate in the spectrometer measurement experiment meeting.

After four hours of flight, the plane landed at the Capital International Airport.

After leaving the airport, they took a taxi to the Electron Positron Collision Center of the Institute of High Energy Physics, and met the team from Xijing Jiaotong University.

The team leader of Xijing Jiaotong University is Xue Wenzhuo. The trio of Xihai University who he warmly welcomes is obviously more enthusiastic towards Wang Hao than the other two. "Welcome, welcome, Professor Wang Hao, I really didn't expect you to come."

"Let our team strength greatly increase!"

"With you, the future Fields, we are not afraid of any job we are assigned."

Xue Wenzhuo's flattery made Wang Hao feel very pressured, he quickly waved his hands and said, "I don't dare to be Fields, I just followed Professor He Yi to come and see, to gather the number of students for the school."

"Don't be humble."

Xue Wenzhuo patted Wang Hao on the shoulder and said, "No one in the whole country knows that you are in the field of mathematics, and you are the top in the country. No one else can compare."

"Those who are younger than you are not as successful as you; those who are more successful than you are not as young as you."

This cliché cannot be refuted at all, because Wang Hao is still far from 30 years old, and most of the successful mathematicians in China are over 30 years old.

After exchanging pleasantries, they went to see the Puyi detection device.

The spectrometer detection device is a part of the electron-positron collider. It is 6 meters high and weighs 500 tons. It looks like a big guy on the outside, and the experimental meeting is also carried out around this big guy.

Xue Wenzhuo introduced, "Don't underestimate this big guy, it is the most delicate part in the electron-positron collider."

"The core of spectrometer measurement is the quark problem and the origin of the asymmetry of matter and antimatter."

"Before, we were studying the decay of pros and cons of Cauchy hyperons, and it became the largest international cooperative research in China. The last time the results were very remarkable, we completed the most accurate decay parameters and asymmetry of pros and cons of Cassy hyperons. Measured, and the results were published in the journal Nature."

"This time I plan to repeat the last experiment, because those with relevant results will attract more people to participate, and the analysis will be more accurate."

Wang Hao asked, "When will the experiment start?"

"It depends."

Xue Wenzhuo explained, "The plan is the morning after tomorrow, but it may be advanced or postponed. It still depends on the coordination of relevant departments."

"Then what do we do?"

"We are all here to do the initial data analysis after the experiment is over." Xue Wenzhuo said, "This kind of data analysis work is very complicated, so I said, with you, we all feel much more relaxed. It's mathematicians."

Xue Wenzhuo still had nothing to say.

They are teams sent by colleges and universities, and they are all marginal 'trained' teams.

The spectrometer measurement experiment is an international cooperative research, and some countries will also send teams here.

Those are the real workhorses.

Some people in the team formed by the university are not professional, and most of them can only do some corner data analysis work, and the results need to be reviewed in detail.

The reason why it is said to be 'trained' is because the level of the team is not up to the level of formal research.

The project supports colleges and universities to send teams over, mainly considering the cultivation of talents, and the purpose is to hope that more outstanding physicists will emerge to prepare for future research and development.

The spectrometer measurement experiment is only a small international cooperation project.

Even if the scale of cooperation is very large, it is nothing compared to the European particle collider project.

China is preparing to design and build a large-scale particle collider. Many people in the academic circle are worried that after the collider is built, it will be used as a wedding dress for foreign countries, because there are not enough talents in China to work for the large-scale collider. There are many jobs. Only relevant foreign scholars can be hired to participate.

Now there are many colleges and universities that can participate in sub-level projects, which is a good opportunity to improve the ability and experience of research participants in colleges and universities.
