Great Country Academician

In a short time, Xu Chuan had already re-planned the future of this life in his mind.

There is no doubt that physics is his root, but this does not prevent him from focusing on mathematics in his life.

The only thing that makes him hesitate is whether to continue to choose to study abroad in this life.

Having stayed in Princeton for more than ten years, Xu Chuan is well aware of Princeton's strong mathematical ability, which is the world's top mathematics campus.

Compared with the physics he studied in his previous life, mathematics is the root of Princeton.

If you want to study mathematics in depth, Princeton is the best choice. There are many Fields Medal winners teaching there all the year round, and you can almost understand most of the subjects in mathematics.

But what Xu Chuan hesitated was that Princeton was in that country, the country that blocked him for 20 years and even sent him 'home' in the end.

Once you go out, whether you can come back is an uncertain thing.

As for not going out and simply staying in China, to be honest, with his current mathematical ability, he is enough to teach in any university in China, and he can't learn much knowledge anymore.

Compared with the other party in the area of ​​basic science, it has to be admitted that his motherland is still far behind, whether it is today 20 years ago or in the future 20 years later.

"Forget it, there must be a way for the car to reach the mountain, let's talk about it then."

Shaking his head, Xu Chuan threw out the entanglement in his mind.

If it is really necessary to go out to study in the future, go out purely as a student of learning knowledge, and don't apply for research involving nuclear energy physics. If you don't show too many achievements, you may not necessarily be noticed.

For him, even if he encountered that kind of thing in his previous life, going abroad is still unavoidable in this life, at least he must go to Europe.

Many of his research theories in his previous life were based on the large and powerful particle collider in Europe.

Although these things are all in his mind now, and he can publish them directly, but this is impossible to do, after all, he doesn't even have experimental data now.

It is a genius to find clues and discoveries from experimental data and to prove the obtained data and theories.

But if you can get data theory without experimental data, there will definitely be many people who want to send you to the operating table.

Of course, if he really doesn't want to go abroad, Xu Chuan can also choose to build a large-scale strong particle collider by himself or ask the country to help him.

But the cost of building this thing is too high, starting at the gold level of tens of billions of meters, and the construction time is too long, calculated in years.

If he builds it himself, money is not a problem. The materials he researched in his previous life can be redeveloped and exchanged for money. But technology is the key, and the complexity of this thing may not be handled by a single country.

It can be said that the large and powerful particle collider in the European Atomic Energy Laboratory was built by almost uniting the forces of the whole world.

If he wanted the country to help build one, he had to show enough grades, not to mention becoming a top student at the Tianting level, but at least he had to become the most influential in the field of high-energy physics in China.

In the quiet classroom, everyone lowered their heads and worked on their own test papers. No one cheated by flipping through the books, and no one spoke to each other.

Xingcheng No. 1 Middle School is one of the four famous schools in Xingcheng. Every year, there are at least two figures of Qingbei students going out from here, and there are countless students from universities such as 985 and 211.

The students who can be admitted to this school don't say how smart they are, but they must work hard.

At least in class 1201, everyone knows what to do and when.

Atmosphere is a very important thing most of the time.

In such a class, even if you are a person who doesn't like learning very much, you will gradually learn it.

For Xu Chuan, the classmates around him brought him not only the gradual recovery of the buried memories in his mind, but also a youthful mentality and vitality.

At this moment, the body and mind of nearly forty years old before rebirth seemed to return to the year when he was seventeen.

The white test paper on the table brought a smile to Xu Chuan's face. He hadn't seen these things for a long time.

"Under a small balloon made of air-filled rubber film, there is a small metal block hanging. When they are placed somewhere in the water, they can just suspend. If you pull them down a little and let go, the metal block and Balloon will()"

"A. Stand still and don't understand, B. Move upwards, and then return to the original position, C. Accelerate downwards and sink to the bottom, D. Move upwards and finally float."

"This topic, again, was written by Old Tang himself."

A multiple-choice question caught Xu Chuan's eyes. He smiled and wrote a letter 'C' in the brackets without hesitation.

This question is actually very simple, but there is a small trap in it. Many people may not be able to switch to B or D after a while.

It's not actually about gravity, but about the effect of water on the balloon.

For a balloon floating in water, the deeper the water, the greater the pressure, the balloon is compressed, and the buoyancy decreases instead, which is less than the gravity, and a downward resultant force is generated, so it will accelerate the sinking instead. It floats upward as most people imagine.

In his previous life, Old Tang liked to do this kind of tricks. He always made up his own questions for all school tests, quizzes, and test tests.

Strictly speaking, the questions are not difficult, but there are some pitfalls in each question.

It is easy to make mistakes if you simply make a judgment at a glance, but as long as you are a little more careful, you will be able to react.

However, it is precisely because of these topics that he has greatly exercised his judgment ability in the initial stage of learning physics, and cultivated his careful habits, which laid the most solid foundation for him to reach the pinnacle of physics in the future.

There are not many questions in one test paper, six multiple-choice questions, four multiple-choice questions, three fill-in-the-blank questions, and two proof questions. Compared with final exams and other test papers, the number of questions is less, but the difficulty is higher.

After all, it is a thorough test, and it is impossible to occupy the time of other classes.

Old Tang was very confident. He knew the abilities of all the students in Class 1201. Most of them could complete this set of questions within 45 points, but the grades depended on how careful they were.

Naturally, it was impossible for Xu Chuan to spend the entire class time on this kind of problem, and he had already solved it in less than fifteen minutes.

For the next half an hour or so, he was immersed in the book. Twenty years later, except for mathematics and physics, he had almost forgotten the contents of the high school textbook.

Especially Chinese and biology, this is not his strong point, many things have to be memorized.

It is really impossible to ask him to recite a complete ancient classical Chinese essay now.

The training camp for IMO and IPHO is about to start, and there is not much time left for him. While there is still some time, hurry up and learn Chinese biology.

It is impossible to get full marks in mathematics and physics in the college entrance examination, but fail in Chinese and biology.

Although it doesn't matter to him whether he takes the college entrance examination or not.
