From University Lecturer to Chief Academician

The afternoon classes started at two o'clock, and at half past one, the big classroom was already overcrowded.

After lunch, many students came to the classroom to occupy seats. Some even came at twelve o'clock, and they couldn't find a seat after 1:30.

Some of the teachers who came in were very surprised to see this scene, and felt like crying and laughing when they looked carefully.

It is impossible for so many students to be graduate students and doctoral students in the Department of Mathematics and Physics, and many of them are juniors and seniors.

They came here after hearing Wang Hao's lecture.

After all, it is a formal open class, and it is impossible for the students to come to listen to the lecture on their own initiative, and they can't find a seat because they came late. Later, a few teachers simply moved chairs to the office next to them, just in front of the most edge aisle, or It's the back seat that has been added to sit down.

At the same time, there was a lot of discussion in the classroom, "Professor Wang finally started class again!"

"I just came here to listen to Mr. Wang's lecture. If you haven't heard it, you may not know. Mr. Wang's lecture is really good!"

"Mr. Jones was giving a lecture in the morning. That American man is not good at all. He couldn't understand what he was talking about..."

"Me too, I don't understand at all..."

"His Chinese is not good, and he speaks fast, how do you listen?"

"The afternoon class seems to be connected to the morning class, right? Is it possible that the difficulty is so high?"

"I don't know, I have to listen to it anyway..."

Paul Phil Jones walked into the classroom amidst the buzz.

He entered the classroom through the main entrance. Seeing the overcrowded scene inside, he immediately stood at the door and rubbed his eyes vigorously, "Why are there so many people?"

Many students left in the morning.

The afternoon class was linked to the morning class, and normally there would not be many students attending the class. He thought that few people would be there, and he was still worried about Wang Hao's class, but he saw such a scene.

Paul Phil-Jones was stunned for a long time, he didn't know whether to go in, because he knew he couldn't find a seat, but fortunately Zheng Yaojun also came, so he sat on the side of the first row and beckoned to the door Waving, "Paul, here!"

Paul Phil-Jones looked up, and simply walked over to sit in the seat reserved by Zheng Yaojun.

After sitting down, he asked in surprise, "Zheng, why are there so many students here?"

"What's the big deal."

Zheng Yaojun said indifferently, "Many students still don't know this, otherwise the classroom would not be able to accommodate it at all."

"Wang Hao's courses are so popular?"

"Of course."

"But the content of his lecture is to connect with the morning..." Paul Phil-Jones hesitated, and continued, "There are not many people left in the morning."

Zheng Yaojun pursed his lips hard, not knowing whether he should answer the conversation, he was also present in the morning, and he couldn't keep up with what Paul Phil Jones said.

He has a specialization in technology, and he is a scholar in the direction of partial differential equations. Naturally, he has no research on theoretical physics.

But thinking about it, Wang Hao was going to give a lecture, so he still came, because Wang Hao's lecture level is notoriously high, and he has listened to several courses, so he felt that it was necessary to come.

Zheng Yaojun didn't answer the conversation, so the topic couldn't be continued.

soon.

Wang Hao came to the classroom.

When Wang Hao stood on the podium, the classroom suddenly fell silent. He looked at the number of people in the classroom, but he was not surprised.

One is fame and the other is teaching level.

As long as he offers open classes, there will be no fewer people coming.

Wang Hao was still a little depressed about the content of the explanation, because it was connected with the content of the morning course, and most people did not understand the morning course.

He still thought of a way.

Many teachers and students in the audience also wanted to see how Wang Hao would start the course.

At this time, Wang Hao said with a smile on his face, "This class is a link to Teacher Jones' class in the morning, and the content starts from the four-dimensional space."

"But before the class, let's review the morning class first."

He officially entered the explanation.

Of course, Wang Hao will not explain the content of the morning again, he just clicked through the knowledge, and then wrote down the conclusions and methods that need to be used one by one on the placed whiteboard.

This process took about half an hour.

Although there was no specific explanation, the conclusions and methods of the knowledge points in the morning were repeated several times in a row, and students were given time to record them carefully.

Then enter the formal explanation.

At this time, it becomes much smoother to go to the next step to explain the content.

"Under the premise of the 'constant speed of light', the space-time theory of special relativity constructed has reshaped human beings' cognition of the universe."

"Space and time are no longer isolated from each other, but are linked together by the movement of matter, forming an inseparable whole..."

"After establishing a new view of space and time, there must be a more elegant mathematical form to unify 'three-dimensional space' and 'one-dimensional time' under the same framework. This is the concept we have heard - Four-dimensional space-time."

"..."

After the opening introduction, the course is moving into the formal content.

There are a lot of complex mathematical analysis content in the middle, and Wang Hao will explain in detail the key and difficult issues.

If he encounters content related to the morning class, he will directly quote the conclusions and methods listed on the whiteboard to make students understand better.

With the help of "Feedback from Teaching", most of the graduate students and doctoral students in the classroom can understand it roughly.

Those undergraduates who have no foundation can also understand the general content.

When you find that you can understand such profound knowledge, there is no doubt that it will arouse the interest of the students, and they will naturally listen more carefully.

This also allowed Wang Hao to get a lot of "gifts of knowledge and understanding", even more than he expected, because some of the knowledge-related content of Paul Phil Jones' explanations were also directly "feedback" to him.

Wang Hao was very surprised. When he took a break in the course, he understood it after careful thought.

Because everyone did not understand the knowledge explained by Paul Phil Jones, but he listed the relevant content on the whiteboard and continued to 'quote', which naturally drove the thinking and understanding of relevant knowledge.

Now I feel that I can always give more knowledge and understanding after teaching a one-hour class.

"That's not bad either!"

"It seems that it is also helpful for Paul to give lectures in advance..."

"Although the students didn't understand it, it doesn't hinder the efficiency of my teaching feedback."

Wang Hao thought strangely.

Paul Phil-Jones sat in the first row and listened carefully. He found that Wang Hao's explanation was really good, which made him feel very rewarding.

There are some content that I didn't understand so deeply before, and I didn't think so much, but after Wang Hao explained it, I felt that I understood it more clearly.

It is difficult for Paul Phil Jones to see such a little gain, because most of the knowledge content is meaningless to him.

He was depressed because he didn't see what happened in the morning.

During the break, he looked back carefully, and found that few students left at all, most of them stayed in the classroom, and everyone listened very carefully.

I waited until the class was all over, that is, nearly three hours later, the classroom was still overcrowded, even a little more than at the beginning, because there were more than 20 students standing in the last row, who obviously came in later, and the result People who can't find a seat.

When he thought about the situation in the morning, he suddenly felt restless.

Lecture by yourself, and the students are gone.

Wang Hao's lecture was still connected with his own content. Not only did the students not leave, but they also listened with great interest, and more and more people came.

This gap is too big.

After all the lessons were over, Paul Phil-Jones walked out of the classroom a little depressed.

Seeing his sad look, Wang Hao certainly knew why, but he still felt that he should give him some comfort, "Paul, don't worry about it."

"Actually, the reason why there are so many students in my course is because this is China and I am very famous."

"Is that so?"

Paul Phil-Jones was a little bit unconvinced, because he thought of the situation where the students left in the middle of the class, "Then why..."

Wang Hao waved his hands vigorously and said, "It's normal. That may have something to do with your Chinese level, not your poor teaching level."

"Oh~~~"

This explanation caught Paul Phil Jones.

yes!

The main reason is that his Chinese level is not standard, and students may not be able to understand some profound knowledge.

He suddenly became motivated again, "I've decided, Wang Hao."

"From today onwards, I will work hard to learn Chinese. It is far from enough just to be able to speak Chinese and communicate. I want to make my pronunciation and oral expression correct to the level of ordinary Chinese!"

"come on!"

Wang Hao gave him a thumbs up.

Paul Phil-Jones nodded firmly. He was really envious of so many people listening to Wang Hao's lectures, and hoped that he could reach this level one day.

This is another achievement that is different from scientific research!

He is very much looking forward to having so many students listening carefully during his lectures after his Chinese has improved.

...

Paul Phil-Jones' work life is indeed very fulfilling. In addition to being motivated to learn Chinese well, he is also working hard on research.

His research direction is to continue to analyze the annihilation force, and the method is to start with the decay problem, and analyze other decay problems on the basis of "the annihilation force has a higher dimension" to see if there are new discoveries.

Even if there is no discovery, analyzing the annihilation force in a new mathematical form is also a contribution to the results related to the annihilation theory.

In fact, some physicists in the world have already started to do similar research.

Wang Hao and Paul Phil Jones analyzed the decay of a particle, and discovered new particles in the process, and there are many decayable particles.

Every kind of decay particle can be analyzed newly, because there are already traces to follow, and the research is like ‘substituting into a formula’, but the basic requirements are relatively high.

If the correct mathematical logic can be shaped and calculated in combination with the Yang-Mills equation, it is naturally possible to find new particles.

Wang Hao is no longer interested in research in this area.

As the founder of the annihilation theory, it is impossible for him to study every content by himself, but it is enough to study the decay of one particle.

The most important thing of this study is to give the basis of ‘the annihilation force dimension is higher than the other three microscopic forces’.

On this basis, other scholars carry out extended research, naturally the higher the results, the better, and the higher the results, it means that they are further away from proving the annihilation force.

For him personally, there are only advantages and no disadvantages.

It is impossible for a single scholar to complete all the research on the content of each physical theory. More scholars must be involved in order to jointly improve the theory.

Wang Hao has not determined the next research direction, and his work life is relatively leisurely.

He occasionally discussed the simplification work of semi-topological micro-morphological geometry with Bill Carr; occasionally paid attention to the research of Paul Phil-Jones;

Today is a big day.

"Acta Mathematica Sinica" released a new issue, and Qiu Hui'an's Legendre conjecture proof was published, which immediately aroused heated discussions in the international mathematics community.

The proof of every conjecture in the field of number theory can be said to be an international mathematical achievement.

This proof was completed by Qiu Hui'an, and the corresponding author's name was Wang Hao. Naturally, many people discussed who Qiu Hui'an was...

Then they knew that Qiu Hui'an was Wang Hao's student, and he was just a graduate student.

This news has aroused heated discussions at home and abroad, "Wang Hao's postgraduate student has actually been able to complete the proof of Legendre's conjecture!"

"Qiu Hui'an, remember this name, the master of number theory in the future!"

"Worthy of Wang Hao's student, he has already proved the problem of number theory while still in graduate school!"

"A thesis published in the "Acta Mathematica" as a master's thesis? What could be more perfect than this?"

"Will this paper win the Zhong Jiaqing Mathematics Award from the Mathematics Society?"

"Not to mention the Zhong Jiaqing Mathematics Award, it is enough to win an international mathematics award!"

The hot discussion of public opinion at home and abroad naturally also affected Xihai University.

Yan Fu of Xihai University specially came to meet Qiu Hui'an, awarded him a bonus of 500,000 yuan on behalf of the school, and even promised to stay in the school to arrange an associate professor position.

"Xiaoqiu, you can work as an associate professor at the school while studying for a Ph. D., and after you graduate with a Ph. D., you can directly become a full professor!

"Don't worry, you will get the treatment you deserve. You are not from Beijiang Province. After graduation, the school will give you a resettlement fee..."

"For talents, the university must give the best care..."

It is clear.

After the thesis was officially published, Qiu Hui'an's worth was completely different.

Before, he was just a graduate student, even if he was a graduate student led by Wang Hao, he was still just a student in essence, but now he has become a talent that colleges and universities compete for.

Yan Fu made a lot of promises in private, but he was still not at ease about Qiu Hui'an's going to stay, so he went to ask Wang Hao specifically.

Wang Hao's only expression was, "Qiu Hui'an will continue to study with me for a Ph.D."

Nothing else.

In fact, Wang Hao didn't care about Qiu Hui'an's stay or stay. It would be nice to have a talented student at Xihai University with him, but it didn't affect him if he left to work in another university after he became famous.

The school does need to develop, but the development of the school is not to retain all talents, but more importantly, to be able to continuously cultivate talents.

...

soon.

Another week passed.

Wang Hao was drinking coffee leisurely in the office when he heard a report that someone was looking for him. He recalled it before he remembered, it seemed that Shen Cheng had contacted him in advance.

He entertained guests in his office.

The person who came was Zeng Haiyu, a researcher at the Shencheng Aero-Engine Research Institute.

Zeng Haiyu was about fifty years old. After meeting Wang Hao, he introduced himself, "Professor Wang, hello, I am Zeng Haiyu from the Institute of Aeronautics."

Wang Hao gave Zeng Haiyu to the sofa politely, then turned around and made a cup of tea for him.

Zeng Haiyu also talked about the purpose of coming here. They are designing a new type of aero-engine, "We hope to improve on the original basis and design and manufacture an aero-engine that reaches the international top level."

"However, problems were encountered in the calculation of the supercharging efficiency of the fan blades."

Zeng Haiyu said with some distress, "The calculation is too complicated. If we can improve the accuracy of the calculation results, we can design a better plan. Professor Wang, you also know that there..."

He said and shook his head.

If an aero engine is compared to a jet balloon, the greater the internal pressure, the faster the balloon will naturally fly. In order to obtain a higher boost ratio and generate greater thrust, the air in the engine usually needs to pass through multi-stage compressor blades compression.

Then, it is very important to improve the supercharging efficiency of the fan blades.

However, in order to improve the supercharging efficiency of fan blades, a more reasonable design is required, and the design involves complex calculations.

The problem that Zeng Haiyu's team encountered was that they had several design plans, but they had no way to determine which one was more suitable. In other words, in which plan, the supercharging efficiency of the fan blades was higher.

"This design is crucial and directly determines the main research direction inside the engine."

"There are endless discussions in the institute now, but there is no definite conclusion. But we have done many calculations, and the result..."

He said with some embarrassment, "Every time the result is different."

Wang Hao thought for a while, then frowned and asked, "So, you have several plans, and you want to know through calculations, which one has a higher fan design pressure?"

"right."

Zeng Haiyu nodded firmly.

"I still don't understand." Wang Hao said after thinking, "The wind pressure of the impeller machinery involves fluid mechanics, and some values ​​need to be substituted for approximate calculations, because the difference in substituted values ​​will also lead to deviations in the calculation results. It will produce, every time the result is different, that's it, right?"

Zeng Haiyu continued to nod, "That's right, the results of our calculations have been different several times in a row, and it is impossible to determine which solution is better."

Wang Hao suddenly wondered, "I don't understand this. Since manual calculations will make mistakes, why don't you use computer simulation calculations?"

"If you use a computer and substitute a large number of values ​​for simulation calculations, even if the deviation range is larger, but there are more data, you will naturally know which solution is better, right?"

This is a matter of probability.

For example, compare plan 1 with plan 2, substitute value 2, the value of plan 1 is higher, substitute value 2, and the value of plan 2 is higher.

Then it is difficult to come to a conclusion which scheme is better to calculate and substitute the values ​​one by one.

If you use a computer simulation to substitute the numbers from '1-10000' in one go, there are 8,000 better options for option one, and 2,000 better options for option two, and option one will naturally become the best choice.

Zeng Haiyu felt like vomiting blood, he opened his mouth and didn't know what to say, and looked at Wang Hao with an expression of "Why don't you eat minced meat".

We are all starving and you ask why we don't eat meat?

Computer simulation calculation?

Even doing manual calculations, they have wasted a lot of energy. If they can have high-end computer simulation operations, they still need to spend time and effort on manual calculations?
