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

In the S+ difficulty level task, the difficulty of the inspiration point increase is a notch higher than the S-level difficulty, and every point of the increase in the inspiration value can be said to be very precious.

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

There is no need to consider other aspects at all, because the students who can come to participate in the re-examination will have very top-notch grades and will not have problems on the basis.

Whether it is suitable for R&D in the future cannot be seen in an interview.

Unless there is a very better kind of genius, you can make a certain achievement at the undergraduate level, and you can see something.

This kind of genius is obviously a rarity.

The more Wang Hao studied mathematics, the more he felt the importance of inspiration, knowledge can be obtained through learning, and inspiration, or the correct idea of research and development and problem solving, cannot be obtained through learning.

Chen Mengmeng's interview performance was worse than others, but if you think about it, it is not bad, she answered the partial differential equation question raised by Zhou Qingyuan, as for the other questions are meaningless at all, everyone's evaluation is different.

"What if Schultz were to come for this interview?"

Wang Hao thought about it carefully and knew that the interview score was likely to fail, maybe Schultz would make a lot of ridicule to several interviewers, and it would be strange if he could have any good feelings at that time.

Is it just a matter of being able to speak?

For Wang Hao, the most important thing is that Chen Mengmeng explained the direction of 'solving problems' according to his own ideas. She said that she should first familiarize herself with the simple problems and then consider the more difficult ones before she can solve them.

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

The NS equation is a nonlinear partial differential equation problem, which is very difficult and complex to solve, and before the further development and breakthrough of the solution ideas and techniques, only some very simple special case flow problems can be found to be accurately solved, and in some cases the approximate solution can be simplified.

So if you want to solve equation problems, the first thing to do is to figure out and understand the problems that can be solved simply.

The system has provided feedback indicating that this is the right way to go.

……

Wang Hao left after making a decision, and as for the other students, just let the interview and evaluation team decide.

The final admission was Chen Mengmeng, Qiu Hui'an, and Xu Jie.

The decision made by the interview review team is not based on a single interview, but on a combination of 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 slightly worse than Chen Mengmeng; Xu Jie's interview performance was very good, coupled with the written test results in the midstream, the comprehensive score ranked third, and he was also admitted.

After determining the list of admitted students, the interview and evaluation team also found the detailed information of the three students, put them together for comparison, and found that there was no problem in admitting Chen Mengmeng, just looking at the resume is indeed the best.

Chen Mengmeng is the top student in the college entrance examination in Northern Xinjiang Province, and her grades in Shuimu University have always been among the highest, she does not need to take the graduate examination at all, and can be directly sent to the graduate school of this university, but I don't know why she still took the exam.

Qiu Hui'an is a student at Donggang University, his grades are relatively mediocre, and he has not been able to obtain the qualification for research and research, but his results in the postgraduate written examination are very good.

Among the three, Xu Jie is relatively poor, and Sudong University is also the top university in China, but there is always a difference between the top and the top, compared to Shuimu University and Donggang University, Sudong University is still worse, in addition, Xu Jie's written test results also have a score, and the interview performance is very good, so he was reluctantly 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 less than Xu Jie's, and she unfortunately failed.

Xihai University also attaches great importance to the unsuccessful students, and compared with the graduate students recruited by other master's and doctoral supervisors in the School of Science, Hu Lidan and Zhang Haijiang are undoubtedly much better.

Several master's and doctoral supervisors directly came forward to persuade them to stay at Xihai University.

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

……

Wang Hao's graduate re-examination is over, and the speed between the announcement of the list of admitted students is very fast, and there is only a two-day gap.

Chen Mengmeng knew it at that time.

She left in a daze after the interview, thinking all the way about why she passed, but she still couldn't think of it at all.

When she got 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, her face was full of doubts and confusion.

She has always been very confident in her mathematics level, and her grades and scores in various mathematics subjects are all above 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, faith seems to have returned.

One of the Seven Mathematical Conjectures?

"No wonder!" Chen Mengmeng rubbed her eyes vigorously, "It's a mathematical conjecture, and it's a very complicated one, no wonder I can't understand it." ”

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

She thought about it for a long time, but she still couldn't come up with it.

While Chen Mengmeng was surprised, several other students who took the re-examination were also surprised.

"You'll never guess what I did in the retest." Xu Jie swore in the group of classmates.

"Didn't you apply for Professor Wang Hao's graduate school? Will he still ask you questions about number theory? A classmate typed back.

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

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

Xu Jie said, "It is indeed a partial differential equation, and my topic is to prove the existence of a class of nonlinear partial differential equations with smooth bounds. ”

As soon as these words came out, the group of classmates suddenly exploded.

"It's difficult!"

"How is this possible!"

"I think this kind of question should be the research content of a doctor or professor, right? Even the simplest ones can't be found in the re-examination questions. ”

Xu Jie continued, "Why are you in a hurry? I'm not done yet, you must have heard of this kind of partial differential equation, the name is Navier-Stokes, how about it, does it feel familiar? ”

“……”

“……”

A bunch of ellipses appeared in the group, and at the end one person typed and asked, "Did you make it?" ”

The ellipses below have become more numerous.

……

After the admission of graduate students in mathematics has been completed, the re-examination for graduate students in informatics has also begun.

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

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

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

Luck is more important in this regard than in selecting students.

However, the professors of the School of Computer Science were very concerned about Wang Hao's recruitment of graduate students, and the old man Chen Qinghua asked with interest, "What are your expectations for students?" ”

Wang Hao thought about it carefully, hesitated and said, "It's no worse than Zhang Zhiqiang." ”

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

He played a long note and finally said, "He's working hard." ”

……

A week later.

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

Xiao Xinyu is another professor in the Department of Physics, and 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 over to make up a number.

Along the way, Wang Hao chatted with Xiao Xinyu a lot.

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

"Stanford University spends $100 million a year on this research, but there is very little to be done."

"Some time ago, a physicist at Ameriken experimentally proved that the high-speed rotation of the superconductor disk in an experimental environment close to absolute zero can cause the mass loss of some objects within the fixed magnetic field range."

"The mass loss of the experimental assay is about 1%, which is a very small amount, 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 anti-gravity is undoubtedly very fascinating.

The flying cars that appear in science fiction movies can float directly in place, and it seems that anti-gravity technology is used.

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

It's just that this technology is still a 'future technology', and even if the academic success of anti-gravity is achieved in an experimental environment, human beings have not yet discovered any specific phenomena from the universe to confirm the existence of anti-gravity.

Some people believe that the universe has only a positive gravitational force, and there can be no negative mass repulsion.

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

He Yi seemed to be 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 study is to find evidence of asymmetry between positive and antimatter."

"The previous spectrometer detection experiments have been able to determine the asymmetric parameters of positive and negative Cosiy hyperons, with an accuracy of 100 billion, and the particle standard model has been verified."

"This time, we will participate in a larger experiment, and it is said that we will eventually conduct detailed data analysis of tens of billions of J/psi particles, and it is expected that the measurement accuracy will be more than three times higher."

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 issue of 'anti-gravity', obviously compared to the anti-gravity of black technology, the determination of the standard model of particles, and the determination of the asymmetry of tiny particles, the attraction is really much worse.

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

After a four-hour flight, the plane landed at the Capital International Airport.

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

The leader of Xijing Jiaotong University is called Xue Wenzhuo, and the trio of Xihai University, whom he warmly welcomed, was much warmer to Wang Hao than obviously to the other two, "Welcome, welcome, Professor Wang Hao, I really didn't expect you to come." ”

"Let's make our team stronger!"

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

Xue Wenzhuo's big set of praise made Wang Hao feel very pressured, and he hurriedly waved his hand and said, "Fields don't dare to be, I just followed Professor He Yi to take a look and make up a number for the school." ”

"Don't be modest."

Xue Wenzhuo patted Wang Hao on the shoulder and said, "Now no one in the country knows that you are the top in the mathematics world, and there is no one else who can compare." ”

"Those who are younger than you are not as fruitful as you; Those who are higher 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 mathematicians in China who have achieved results are over 30 years old.

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

The spectrometer detection device, which is part of the positron collider, is 6 meters tall and weighs 500 tons.

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

"The core of the research of spectrometer measurement is the quark problem and the asymmetric origin of positive and antimatter matter."

"Previously, we were studying the decay of positive and negative Cosion hyperons, and it has become the largest international cooperative research in China, and the results of the last time were very remarkable, completing the most accurate measurement of the decay parameters and asymmetry of positive and negative Cosi hyperons, and the results were also published in the journal Nature."

"This time I am going to repeat the last experiment, because there are more people who participate in the relevant results, 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, depending on the coordination of relevant departments." ”

"So what do we do?"

"When the experiment is over and we do the initial data analysis, we will do this." Xue Wenzhuo said, "This kind of data analysis work is very complicated, so I said, with you, we all feel much easier, and the most missing thing here is mathematicians." ”

Xue Wenzhuo still didn't have anything to say.

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

Spectrometer measurement experiments are international cooperative research, and some countries will also send special teams to come.

Those are the real workhorses.

Some of the teams formed by universities are not professional, and most of them can only do some marginal data analysis work, and the results need to be reviewed in a detailed report.

The reason why I say 'trained' is because the level of the team is not up to the level of formal research.

The project support allows universities to send teams over, mainly to consider cultivating talents, with the aim of hoping that more excellent physicists will emerge to prepare for future research and development.

Spectrometer measurement experiments are only a small international cooperation project.

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

China is preparing to design and build a large-scale particle collider, and many people in the academic community are worried that after the collider is built, it will be a wedding dress for foreign countries, because there are not enough talents in China to work for the large collider, and many positions can only be involved by foreign scholars.

Nowadays, many universities can participate in second-level projects, which is a good opportunity to improve the ability and experience of research participants in universities.
