Chapter 136 The most lacking thing here is mathematicians!
Wang Hao's evaluation criteria are very direct. Students who can bring inspiration are good students.
For S+ difficulty level tasks, the difficulty of increasing the inspiration value is one level higher than the S level difficulty. Every point of improvement in the inspiration value can be said to be very precious.
If there is a student who can bring some 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 take the re-examination will all have top-notch scores and basically there will be no problems.
Whether you are suitable for research and development in the future cannot be determined in just one interview.
Unless there is a very outstanding genius who can produce certain results at the undergraduate level, he can see something.
This kind of genius is obviously rare.
The more Wang Hao studied mathematics in-depth, the more he felt the importance of inspiration. Knowledge can be obtained through learning, but inspiration, or research and development, and the correct ideas for solving problems cannot be obtained through learning.
Chen Mengmeng's interview performance was worse than others, but it was not bad if you think about it carefully. She answered the partial differential equation question raised by Zhou Qingyuan. As for the other questions, it was completely meaningless, and everyone's evaluation was different.
"What would happen if Schultz came to this interview?"
Wang Hao thought about it carefully and realized that he would probably fail the interview. Perhaps Schultz would make a lot of ridicule to several interviewers, and it would be surprising if he would have any favorable impressions at that time.
For mathematical research, does it suffice 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 her own ideas. She said that only by familiarizing yourself with simple problems and then considering more difficult problems can the problem be solved.
This sentence seemed meaningless, but it brought inspiration to Wang Hao.
The NS equation is a nonlinear partial differential equation problem, which is very difficult and complex to solve. Before further development and breakthroughs in solving ideas and techniques, accurate solutions can only be obtained for some very simple special case flow problems. In some cases,
The situation can be simplified to obtain an approximate solution.
So if you want to solve an equation problem, the first thing you have to do is to figure out the simple solvable problem and understand it.
The system fed back relevant information indicating that this was a correct idea.
…
Wang Hao left after making his decision. As for other students, just let the interview review team make the decision.
The final ones admitted were Chen Mengmeng, Qiu Hui'an, and Xu Jie.
The interview review team makes a decision not based on one interview, but on a combination of the interview and written test scores.
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, and combined with his mid-range written test score, his overall score ranked third, also
Admitted.
After confirming the list of admitted students, the interview review team also specially found the detailed information of three students and compared them together. They found that there was no problem in admitting Chen Mengmeng. Looking only at resumes, he was indeed the best.
Chen Mengmeng was the top scorer in the college entrance examination in Northern Xinjiang Province, and her grades at Shuimu University have always been among the best. She did not need to take the postgraduate examination at all, and was directly recommended to study at this school, but she did not 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 postgraduate qualifications, but his postgraduate written examination scores are very good.
Among the three, Xu Jie is relatively worse. Soudong University is also a top university in the country, but there is always a difference between top and top. Compared with Shuimu University, Donggang University, and Soudong University, it is still worse. In addition, Xu Jie’s written test scores
There were also score points, and I performed very well in the interview, so I was reluctantly admitted.
The other two, Hu Lidan and Zhang Haijiang, are really a pity.
Although Hu Lidan's interview performance was pretty good, her written test score was also the worst. Zhang Haijiang's overall score was only a little lower than Xu Jie's, and he unfortunately failed to be selected.
Xihai University also attaches great importance to the unsuccessful students. 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 study for graduate school with Zheng Yaojun and engage in the study and research of partial differential equations.
…
Wang Hao's postgraduate re-examination was over, and the list of admitted students was announced very quickly, with only two days between them.
Chen Mengmeng knew it at that time.
After the interview, she left in a daze, thinking about why she passed, but she still couldn't figure it out at all.
After returning home, she told her parents that she had been admitted. Then she looked up the interview questions and immediately found the relevant information——
NS equation.
One of the seven great mathematical conjectures of the millennium?
When Chen Mengmeng saw the content on the webpage, doubts and confusion were written all over his face.
She has always been very confident in her math skills, and her scores in all math subjects were all A-level or above. However, after going to the interview, she felt that she suffered a big blow. She couldn't even understand the questions.
Now, confidence seems to be back.
One of the seven major mathematical conjectures?
"No wonder!" Chen Mengmeng rubbed his eyes vigorously, "It's actually a mathematical conjecture, and it's a very complicated one. No wonder I can't understand it."
"Why did Professor Wang use this as the title?"
She thought about it for a long time but still couldn't figure it out.
When Chen Mengmeng was in surprise, several other students who took the reexamination were also surprised.
"You will never guess what questions I did in the re-examination." Xu Jie said confidently to the group of classmates.
"Didn't you enroll as a graduate student under Professor Wang Hao? Wouldn't he still ask you questions about number theory?" A classmate typed a reply.
"It's a partial differential equation." Xu Jie reminded.
"It turns out it's a partial differential equation. That's not surprising. I've studied it carefully and found that 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 he said this, the classmate group immediately exploded.
"It's very difficult!"
"How can this be!"
"I feel like this kind of question should be the research content of a doctor or a professor, right? Even the simplest question is unlikely to appear in the postgraduate re-examination questions."
Xu Jie continued, "What are you so anxious about? I haven't finished 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 ellipses appeared in the group, and finally someone typed and asked, "Have you made it?"
There are more ellipses below.
…
After the admission process for graduate students in mathematics has ended, the re-examination for graduate students in informatics has also begun.
This time, Wang Hao did not give any more questions to the students, but asked several questions about codes and algorithms on the spot.
Compared with the high requirements of mathematics, Wang Hao believes that the information science direction is more important than personal knowledge and ability level. If you can have more mathematics as a foundation, it is of course the best.
Wang Hao does not have high requirements for students in information science. Most of them are mediocre. If you want to expect students to win any international awards in the future, the possibility is really low.
Luck is more important than selecting students in this regard.
However, the professors of the School of Computer Science were very concerned about Wang Hao's recruitment of graduate students. Old man Chen Qinghua asked with interest, "What are your expectations for the students?"
Wang Hao thought about it carefully and said hesitantly, "As long as it's no worse than Zhang Zhiqiang."
Chen Qinghua thought about it carefully and made a small comment, "Actually, Zhang Zhiqiang's level..."
He sounded a long note and finally said, "He works very hard."
…
One week later.
He Yi and Xiao Xinyu from the Department of Physics flew to the capital with Wang Hao.
Xiao Xinyu is another professor in the Department of Physics. He has done 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 people.
Wang Hao talked more with Xiao Xinyu along the way.
Xiao Xinyu talked about the latest research on superconductivity, which is directly related to the very attractive "antigravity". "No scientist has dared to say that he is studying antigravity before."
"Stanford spends $100 million a year on this research, but has almost no results to show for it."
"Some time ago, an American physicist used experiments to prove that a superconducting disk rotating at high speed in an experimental environment close to absolute zero can cause the mass loss of some objects within a fixed magnetic field."
"The experimental measurement of 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 antigravity in an experimental environment.”
The study of antigravity is undoubtedly very fascinating.
The flying cars that appear in science fiction movies can float directly on the spot, seemingly using anti-gravity technology.
And if you want to build that kind of car, only anti-gravity technology can achieve it.
It's just that this technology still belongs to "future technology". Even if anti-gravity academic success is achieved in an experimental environment, humans have not discovered any specific phenomena in the universe to confirm the existence of anti-gravity.
Some people believe that the universe only has positive gravity and there cannot be repulsive force of negative mass.
Wang Hao and Xiao Xinyu found it very interesting along the way.
He Yi seemed a little unwilling to be left alone, 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 most important thing about this research is that we hope to find evidence of the asymmetry of matter and antimatter."
"Previous spectrometer detection experiments have been able to measure the asymmetry parameters of positive and negative Corsi hyperons with an accuracy of hundreds of billions, verifying the Standard Model of Particles."
"The experiment we are going to participate in this time is larger. 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 be improved by more than three times."
After He Yi finished speaking, he waited for the two of them to ask questions.
In the end, 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 measurement of the standard model of particles, and the measurement of asymmetry of tiny particles, the attraction is really far behind.
too much.
Of course, the purpose of their coming to the capital was to participate in the spectrometer measurement experiment meeting.
After a four-hour flight, the plane landed at 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 named Xue Wenzhuo. He warmly welcomed the trio from Xihai University, and was obviously more enthusiastic about Wang Hao than the other two. "Welcome, welcome, Professor Wang Hao, I really didn't expect you to come."
"It will greatly increase the strength of our team!"
"With you as the future Fields, we won't be afraid of any job we are assigned."
Xue Wenzhuo's large set of compliments made Wang Hao feel very pressured. He quickly waved his hands and said, "Fields doesn't dare to take it seriously. I just followed Professor He Yi to have a look and gather the number of students for the school."
"Don't be modest."
Xue Wenzhuo patted Wang Hao on the shoulder and said, "Who in the country doesn't know that you are the best in the field of mathematics in the country, and no one else can compare with you."
"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 accomplished mathematicians in China are over 30 years old.
A few people exchanged pleasantries and then went to see the Puyi detection device.
The spectrometer detection device is part of the electron-positron collider. It is 6 meters tall and weighs 500 tons. It looks like a big guy on the outside, and the experimental conference is also organized around this big guy.
Xue Wenzhuo said, "Don't underestimate this big guy. It is the most delicate component in the electron-positron collider."
"The core of the research on spectrometer measurement is the quark problem and the origin of the asymmetry of matter and antimatter."
"Previously, we were studying the decay of positive and negative Corsi hyperons, and it became the largest international collaborative research in China. The results last time were very significant, and we completed the most accurate decay parameters and asymmetry of positive and negative Corsi hyperons. Sex measurement, the results were also published in the magazine Nature."
"This time we are planning to repeat the last experiment, because 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 for the morning of the day after tomorrow, but it may be brought forward or pushed back. 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. What is lacking here is the most He is a mathematician."
Xue Wenzhuo still had nothing to say.
They are a team sent by universities, and they all belong to the marginal "cultivated" team.
The spectrometer measurement experiment is an international cooperative research, and some countries will send special teams here.
Those are the real main force.
Some people in 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 detail.
The reason why it is said to be "cultivated" is because the team's level is not high enough to conduct formal research.
Project support allows universities to send teams here, mainly to consider cultivating talents. The purpose is to hope that more outstanding physicists will emerge to prepare for future research and development.
The spectrometer measurement experiment is just a small international cooperation project.
Even though the scale of the 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 community are worried that after the collider is built, it will be used as a wedding dress for foreign countries, because there are simply not enough talents in China to work for the large-scale collider, and there are many jobs. Only relevant foreign scholars can be hired to participate.
Nowadays, many universities can participate in sub-level projects, which is a good opportunity to improve the abilities and experience of research participants in universities.
