In a short period of 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 his studies on mathematics throughout his life.
What makes him hesitate is whether he should continue to study abroad in this life.
Having stayed at Princeton for more than ten years, Xu Chuan is very aware of Princeton's strong mathematical capabilities. It is the top mathematics campus in the world.
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 year round, and you can have an in-depth understanding of most mathematics subjects.
But what Xu Chuan hesitated about was that Princeton was in that country, the country that had blocked him for twenty years and even sent him "home" in the end.
Once you go out, it's uncertain whether you can come back.
As for not going out and simply staying in China, to be honest, with his current mathematics ability, he is enough to teach in any university in China, and he will not be able to learn too much knowledge.
In terms of basic science, compared with the other party, it has to be admitted that his country is still far behind, whether it was twenty years ago today or twenty years from now.
Many of his research theories in his previous life were based on the Large Strong Particle Collider in Europe.
Most of the time, atmosphere is a very important thing.
In his previous life, Old Tang liked to do this kind of trick. All school tests, quizzes, basic tests and other exams always came up with his own questions.
If you just glance at it and make a judgment, it is easy to make mistakes, but as long as you are a little careful, you can react.
At least in class 1201, everyone knows what to do and when.
In such a class, even if you are a person who doesn't like learning at first, you will gradually learn to follow.
It is a genius to be able to find clues and discoveries from experimental data and prove the data and theories.
Xingcheng No. 1 Middle School is one of the four famous schools in Xingcheng. Every year, there are at least double digits of Qingbei students who go out from here, and there are countless students from colleges and universities such as 985 and 211.
But the cost of building this thing is too high. It starts at a gold level of 10 billion meters, and the construction time is too long, measured in years.
Especially Chinese and biology, which are not his strong points, and many things need to be memorized.
The white test papers on the table brought a smile to Xu Chuan's face. He hadn't seen these things for a long time.
At this moment, the body and mind that were nearly forty years old before rebirth seemed to have returned to the time when I was seventeen years old.
But if you can get data theory without experimental data, many people will definitely want to send you to the operating table.
There are not many questions in a test paper, including six single-choice questions, four multiple-choice questions, three fill-in-the-blank questions, and two proof questions. It has fewer questions than a final exam, but it is more difficult.
This question is actually very simple, but there is a little trap in it. Many people may not be able to change their minds and choose B or D for a while.
Old Tang was very confident. He knew the abilities of all the students in Class 1201, and most of them could complete this set of questions within forty-five minutes. However, the results depended on their level of care.
Of course, if he really doesn’t want to go abroad, Xu Chuan can also choose to build a large strong particle collider by himself or let the country help him.
The students who can get into this school don't say how smart they are, but they must work hard.
If it is really necessary to go out to study in the future, just go out as a student learning knowledge. Don't participate in research applications involving nuclear energy physics or the like. If you don't show too many achievements, you won't necessarily be noticed.
For a balloon floating in water, the deeper the water, the greater the pressure. The balloon is compressed less, and the buoyancy force decreases, which is less than the gravity it exerts, resulting in a downward resultant force, so it will accelerate sinking instead.
It floats upwards as most people imagine.
Strictly speaking, the questions are not difficult, but there are some traps in each question.
"A. Stay still and don't understand, B. Move upward and then return to the original position, C. Accelerate downward and sink to the bottom, D. Move upward and finally float."
For the next half hour or so, he was immersed in books. Twenty years later, except for mathematics and physics, he had forgotten almost everything else in the high school textbooks.
If he builds it himself, money is not a problem. The materials he researched in his previous life can be re-developed and used in exchange for money. But technology is the key, and even one country may not be able to handle the complexity of this thing.
In the quiet classroom, everyone lowered their heads and worked on their test papers. No one was flipping through books to cheat, and no one was talking or talking.
However, it is precisely because of these questions that he greatly exercised his judgment ability in the initial stage of learning physics and cultivated his careful habits, laying the solid foundation for him to reach the pinnacle of physics in the future.
"Under a small balloon made of rubber film filled with air, there is a small metal block hanging. When you put them somewhere in the water, they can just float. If you pull them down a little and let go, the metal block and
Balloon will()”
For Xu Chuan, the classmates around him brought him not only the gradual resurgence of the memories that had been deeply buried in his mind, but also a younger mentality and vitality.
Although these things are in his mind now and he can publish them directly, it is impossible to do it. After all, he does not even have experimental data now.
If he wants the country to help build one, he has to show sufficient results. Not to mention becoming a scholar at the level of Tianting, but at least becoming the most powerful voice in the field of high-energy physics in China.
The Large Strong Particle Collider at the European Atomic Energy Laboratory can be said to have been built with the combined efforts of almost all the world.
After all, it is a basic test and cannot take up time from other classes.
It was naturally impossible for Xu Chuan to spend the entire class on this kind of question. In less than fifteen minutes, he had already solved it.
Shaking his head, Xu Chuan threw away the entanglements in his mind.
For him, even if he encountered something like that in his previous life, it was still inevitable to go abroad in this life, at least to Europe.
What it actually tests is not gravity, but the effect of water on the balloon.
"Old Tang himself came up with this topic."
A multiple-choice question came into Xu Chuan's eyes. He smiled, and then wrote the letter 'C' in the brackets without hesitation.
"Forget it, there will be a way for the car to reach the mountain. Let's talk about it then."
Now if he is asked to memorize a complete ancient Chinese text, he really can't do it.
The training camp for IMO and IPHO is about to begin, and there is not much time left for him. While there is still some time, he should 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 have much impact on him whether he takes the college entrance examination or not.
