Chapter 38: Is this really a study group?
Hu Zheng came back to his senses after hearing Xu You's question.
"Well... don't erase it yet, continue writing later."
Since Xu You has already written so much, Hu Zheng also wants to temporarily change the teaching method.
Why not let Xu You explain this question?
"Everyone, stop writing and look up at the blackboard. Xu You, just tell us your process."
Hu Zheng simply sat in Xu You's seat and vacated the podium for Xu You.
Not only can I exercise the students, but I can also have a rest, which is killing two birds with one stone.
It was a rare occasion for everyone to encounter such a scene, so they all raised their heads and looked at Xu You with a smile.
After spending such a long time with Xu You, everyone basically no longer regards Xu You as a competitor.
For someone who is far stronger than you, you can only look up to him and pay your respects.
However, Xu You had no experience in giving lectures on the podium, so he had to bite the bullet and start explaining.
"For the focus P, the distance difference between the fixed points PO and PM is half a wavelength. Let the distance from P to the center of the small hole be r0. According to the half-wave band method, we have..."
When Xu You explains the questions, he does not have the teaching skills of a professional teacher.
Not only did he not make eye contact with students, he even accidentally blocked the content on the blackboard when he turned his back to the students.
But it does not affect everyone's ability to understand Xu You's ideas.
In a class of this level, professional ability is far more important than teaching skills.
"It sounds like there's nothing wrong with it. It should be the correct answer."
"I did misanalyze these steps. Point P0' is not a cancellation point, but a strengthening point."
"Has Xu You done this problem before? He did it so smoothly."
After finishing the previous part, Xu You could finally erase the previous part and complete the last part of the process.
After finishing explaining the whole question, Xu You looked at Hu Zheng who was sitting under the podium.
"Well, Xu You, you did a good job. You can get full marks. But you should try to calculate with a pen next time. Even though you got it right this time, you may not be able to see it all with your eyes ."
Hu Zheng also knew that this time, he really had nothing to say to Xu You.
Just a few days ago, Hu Zheng said that no one here has the ability to enter the national group.
If possible, Hu Zheng really wanted to take back what he said.
But Hu Zheng couldn't lose face in front of the students, so he gave Xu You advice in the tone of a teacher.
"Yes, teacher, I understand."
Xu You walked down the ladder, giving Hu Zheng enough face and not making Hu Zheng feel embarrassed.
The students saw it but didn't say anything.
But deep down, I couldn't help but discuss this matter with my friends.
After class, seeing that Hu Zheng was still in the classroom, no one dared to speak loudly.
Instead, they took out their mobile phones and joined the "Ningjiang Physics Team".
[Huang Qingzhong: Youshen is awesome! Teacher Hu is so speechless. If this happens a few more times, Youshen will replace Teacher Hu.]
[Wei Lan: Who would have thought that the team members would start giving lectures to the coach just a few days into the training camp? Do you think Teacher Hu could solve this problem without writing?]
[Dong Ming: Youshen, have you ever done this question before? Tell us you have done it so that we can feel better.]
[Hu Shucheng: I guarantee with my vast experience in answering questions that this question is definitely a new one. Alas, people are really incomparable.]
[Qu Tianxu: What nonsense ! Xu You is a god, and we are human. How can humans compare with gods?]
Xu You felt his phone vibrating continuously and started checking the messages.
After finding out that it was a bunch of meaningless spam messages, Xu You was a little disappointed.
I originally wanted to learn something through this group.
As it turns out, it's all meaningless flattery.
When the group was first created, everyone could actually discuss and learn in the group.
But within a few days, the atmosphere in the group gradually changed.
It is clearly a study group, but apart from studying, people can talk about almost anything.
Disappointed, Xu You opened the group message settings and clicked the "Do Not Disturb Messages" button.
In an instant, the phone finally became quiet.
"Xu You, don't you want to express your thoughts?"
Seeing that Xu You didn't speak, Hu Shucheng asked jokingly.
"What are you talking about? Are you discussing who in the class has the highest level of 3-methylindole in the intestine?"
Upon hearing this, Hu Shucheng quickly waved his hand.
"No, no, studying is more important."
…
In a few days, the provincial team selection for the Ningjiang Province Mathematical Competition will begin.
Xu You asked Hu Zheng for half a day off to take the exam.
In fact, Hu Zheng was somewhat reluctant at first.
After all, at this time, the focus should be on physical competition.
But I heard that Xu You also ranked eighth in the provincial mathematics competition.
Hu Zheng really had no reason to refuse.
Hu Zheng also knew that there would indeed be a very small number of children who had the ability to enter the national training team in both physics and mathematics.
You cannot kill a child's precious opportunity just for a little selfish gain.
The location for the mathematics competition is set up in the School of Mathematics of Ningjiang University.
Ningjiang University is not too far from Shengcheng University. After Xu Youda got up in the morning, he took a taxi directly there .
Xu You is quite familiar with Ningjiang University.
Because Xu You's father, Xu Zhou, worked at Ningjiang University.
When he was young, Xu You would often come to Ningjiang University to play or go to Xu Zhou's laboratory.
"School of Mathematics 403... found it."
When he arrived at the classroom door, Xu You explained his purpose and showed his ID.
Amidst a sea of surprised looks, Xu You found his seat and sat down.
No one had ever seen Xu You before, and everyone was a little surprised by his sudden appearance.
How could a student who didn't even attend the training camp come directly to take the selection exam?
But at this time, no one dared to ask this question.
The teachers in charge of the mathematics competition know a little about Xu You's situation.
"Is this the kid who ranked eighth in the province and hasn't participated in the training camp yet?"
"Yes, that's him, Xu You. He ranked first in the province in physics competition and eighth in mathematics competition. This kid is really not simple."
"I heard that Mathematical Competition is just his secondary subject. He didn't study hard, but he ranked eighth in the province. What would happen if he put all his effort into studying Mathematical Competition?"
"I think it shouldn't be a big problem for him to get into the provincial team. Fortunately, the national finals for mathematics and physics are staggered. After he finishes the national finals for physics, he should be able to focus on mathematics."
At 8 o'clock, the selection examination officially began.
Like the physics competition, the provincial team selection examination for the Ningjiang Province mathematics competition also adopted the standards and difficulty of the national finals.
However, the normal national mathematics competition will be held over two days, testing Mathematics 1 and Mathematics 2 respectively.
In order to save time, this selection competition only tests mathematics.
It also slightly reduces the difficulty of the inspection.
Although there is a full 4 and a half hours of answering time.
But the whole test paper only has three questions.
You can imagine how difficult each of these questions is.
"Luckily I crammed last night, otherwise I wouldn't have been able to solve any of the problems."
After Xu You glanced at the questions, he couldn't help feeling a little scared.
