Chapter 62 I Have a Better Way
Lin Shi refused to accept.
Very dissatisfied!
It is clearly to prove that girls can also win the physics competition championship.
But in the end it was just a little bit off.
In this national training camp, Lin Shi was determined to let Xu You see who the real king of physics was.
Xu You vaguely felt a murderous aura around him.
However, after experiencing scientific research life in the laboratory.
Xu You has become less interested in competition.
The personal honor brought by the competition is no longer important to Xu You.
Xu You only hopes that he can represent China and win the next IPhO team championship in the future.
Defend China's honor in physical competition.
Gradually, all the members of the formal training team, as well as the students who were attending the class as auditors, came to the classroom one after another.
The coach in charge of the national training also entered the classroom.
"Let me introduce myself. My name is Cao Quanli, an associate professor at the School of Physics of Jilin University. I won the first place in the 22nd CPhO gold medal and the first place in the 37th IPhO gold medal. In the next training camp, I will serve as your head coach."
When the students heard Cao Quanli's self-introduction, they couldn't help but exclaim in amazement.
This was once the first place in the International Physics Olympiad.
"The first training session is also the selection of national team members. After the first training session, there will be an internal selection test. The top five will become official members of IPhO and represent China in the World Physics Olympiad. The 6th to 13th will become official members of APhO and compete in the Asian Physics Olympiad."
Everyone knows about this matter.
Among the 50 training team members, only 13 are qualified to represent China in the competition.
Of course, since all the training team members have been recommended by Jingbei, the atmosphere is not as tense as during the previous provincial team training.
Even so, every member of the training camp team participated in this training with the mentality of joining the national team and winning glory for the country.
After explaining some basic matters, Cao Quanli began the formal lecture.
As everyone expected, the national training courses faster and more difficult than those of the provincial team training.
Everyone tried their best to barely keep up with Cao Quanli's speed.
Luo Wenkun put away his nonchalant look and finally showed some of the temperament of a good student.
Lin Shi pinned up her bangs, tied her hair up, and put her brain into performance mode.
Xu You's condition was not much different from before the class.
For Xu You, what Cao Quanli said was not very difficult.
Many of them were things I had already known before or had learned while auditing at Ji University.
Only when I suddenly think of something.
Only then will Xu You enter a state of deep learning and engage in divergent thinking.
Different from other students who are in a state of panic.
Xu You moved easily between the classroom and his own thoughts.
After a three-hour class.
Most of the students have reached their physical and mental limits.
This is the intensity of national training.
Only a few people such as Xu You, Lin Shi, Luo Wenkun, etc. can keep up with Cao Quanli's pace.
"After listening to this class, it feels like I ran 10,000 meters."
"Now it seems that the provincial team's training intensity is really weak."
"It feels like I swallowed several kilograms of food in one go, and it takes me half a day to digest it after returning home."
After class, everyone complained about the intensity of the national training.
But after all, the purpose is to select the best physics contestants in the whole of China.
Such high-intensity training is also essential.
After a few days, everyone finally got used to this intensity.
But the three-hour class is not the most terrible thing.
After completing a small stage of teaching, the training team will have to conduct more intensive mock exam training.
In order to adapt to the intensity of IPhO, each exam will last for 5 consecutive hours.
During this period, students were not even allowed to go to the toilet or get water.
Of course, there is no such rule in IPhO.
However, in a real competition, such a habit will waste team members' time in answering questions and will also affect the rhythm of answering questions.
Therefore, try to let the team members adapt in advance so that they can achieve better competitive state in the examination room.
In every mock exam, Xu You got the first place with full marks or close to full marks.
No matter how hard Lin Shi tried, she could only come in second place every time.
This also made Lin Shi, who was eager to try at the beginning, gradually give up chasing Xu You.
This guy Xu You really doesn't look like a human being.
As for why Xu You sometimes doesn’t get full marks.
It’s not that there’s anything wrong with Xu You’s thinking.
Because in IPhO, the process division will be changed very strictly.
Therefore, as long as there is any problem in the student's answer, the teacher will strictly deduct points according to the standards.
Even a small skip is not allowed.
This is also what Cao Quanli wants to do to help his team members develop good answering habits so that they don't get deducted points by examiners because of the process during the IPhO grading.
On this day, in a normal class.
Cao Quanli talked about a big question about electromagnetism.
This question involves the problem of electric potential distribution of circular arc-shaped conductors.
This was also a very difficult question. It took Cao Quanli a full hour to finish explaining it.
"Wait a minute... Can we use the inversion method for this place?"
Suddenly, in the process of divergent thinking, another solution appeared in Xu You's brain.
This solution is much simpler than Cao Quanli's method.
Because in IPhO, answering time is very precious.
If you can complete the solution to a problem in a faster time.
That will be of great help to the entire exam.
"The inversion method... I remember it was mentioned in Continuum Electrodynamics, but there was no proof of the process."
Xu You felt that if he could prove it, he could use this method in the exam.
Excited, Xu You quickly picked up the pen and started to deduce on the notebook.
Xu You currently cannot imagine a deduction of this difficulty out of thin air.
But I have already formed a general idea in my mind.
Just a few more details to work on on paper.
The entire derivation process can be linked together.
As long as we can prove that Laplace's equation is invariant to inverse transformation, it will be enough.
Taking advantage of his good condition, Xu You carried out the deduction smoothly.
"It's done!"
In less than ten minutes, Xu You completed the entire derivation process.
This is still the case of the first derivation.
If he was skilled, Xu You could complete the derivation of the entire process within five minutes.
In comparison, Professor Cao Quanli's method takes about 20 to 30 minutes to complete this step.
Excited, Xu You wanted to discuss this issue with Cao Quanli immediately.
But thinking that class time was precious, Xu You decided to discuss it with Cao Quanli after class.
