Rebirth Plan to Save Leader - Chapter 63

The gentle spring, sweet love, and intense competition training do not conflict.

Lin Ping is teaching them three times a week, each for two hours.

The progress of his lectures is very fast, and the content is very jumpy, not according to the teaching materials at all.

Tonight was another evening of lectures, and several classmates from the material competition class were lying on the table waiting for him.

I really don’t want to take this old dog’s class. Anyway, I don’t have to learn it again after class.

But what should come has to come.

Lin Ping walked in from outside the teachers face-free, without looking up at them, and turned to the lecture page: “Today I will talk about Coriolis force.”

All the students below: “???”

What? So that part of the angular momentum theorem is over?

Angular momentum theorem and rotation theorem is a very difficult piece in the mechanics competition, he actually finished it in one and a half months. The practice questions were also piled down casually, and he didn’t change the homework for them, and let them finish the correct answers by themselves.

Everyone did not learn well, and they did a lot of stumbling when doing exercises.

This is so confused, just started talking about Coriolis? It’s too jumping…

Lin Pingzheng briefly introduced a few sentences and copied the formula on the blackboard with a chalk.

When everyone was studying rigid body mechanics, they barely accepted a lot of cross-products, differentiation, and superficial integration operations. At this moment, looking at the formula derivation on the blackboard, everyone was confused.

Even Zhang Man felt a headache and looked dizzy.

For high school students, it is basically the same knowledge points as the heavenly book. He actually took 15 minutes to finish it from beginning to end.

And the idea is very jumpy.

Lin Ping was drawing the derivation diagram of Coriolis force and finished writing the formula lightly, giving them five minutes to comprehend.

Although Cao Zhixue could not understand, he planned to write it down first.

“V=dr/dt=v’＋wXr’＋vr……”

“Then a=dv/dt…”

As a result, the formula was erased halfway through.

Let people not learn?

“Fuck.”

He put the pen aside, did not hold back, and cursed softly.

Unexpectedly, Lin Pingzheng heard this sentence. He glanced at him contemptuously, wiped the last vector symbol on the blackboard, and pushed his glasses.

“Why, my mind is slow, and my hands are not long? Cao Zhixue, Zhang Man, come up and re-derive the formula I just wrote.”

This is the end of the story, and someone needs to repeat it? how is this possible……

After learning, Cao Zhi looked at Lin Ping angrily with his neck for a few seconds, but in the end he didn’t say anything, pushed aside his chair, stood up, and went to the podium.

Zhang Man also put down the pen and shook his head helplessly.

She hadn’t figured out the Coriolis force when she was studying mechanics in college, and in fact, the content would not be deduced by students during the competition exam.

Although it is not too difficult in physics knowledge points, it is too complicated and too obscure for high school students.

She stood up, just about to walk to the podium, but was gently pulled by the sleeve of the boy.

“Teacher, I will write for them.”

The boy’s voice didn’t fluctuate, his eyes looked darkly at Lin Pingzheng, making people unable to see what he was thinking.

Not very happy anyway.

Lin Ping sneered: “You write for them? Okay, you will have done the exam for them when the time comes.”

Cao Zhixue turned his head and gritted his teeth: “Li Wei, it’s okay, I’ll write it myself.”

The big deal is just a few cynicisms like before, and I can’t let him help every time.

Zhang Man also gave him a soothing look, and gently opened his hand holding her sleeve.

She took a piece of chalk from the podium and walked to the blackboard on the right.

Coriolis force describes the deviation of a mass point that moves linearly in a rotating system due to inertia.

She thought for a long time, but didn’t recall what Lin Ping said just now-what he said was really fast and messy.

So she planned to make hard calculations based on the coordinate system, hard differentiation. She wrote a few formulas following her own thoughts, but how could she understand the knowledge points that she hadn’t understood for so many years.

Halfway through writing, I still get stuck.

Cao Zhixue was even more miserable, so he wrote a dr/dt formula at the beginning, but he blushed and couldn’t write the next one.

Lin Ping was looking at their embarrassment. He didn’t have the urgency of being a competition coach or caring for students. Instead, he looked ridiculous and disdainful.

The sense of superiority in his eyes seemed to pierce the faces of the two of them.

Zhang Man took a deep breath, turned around, and put the chalk in the chalk box: “Teacher, I won’t.”

Any more stalemate is a waste of time.

But Cao Zhixue choked on his chest and couldn’t swallow. Although he couldn’t, he just stood on the podium and said nothing.

A face was flushed long ago.

Lin Ping was showing weakness to Zhang Man, sneered disdainfully, but didn’t say anything, and focused on Cao Zhixue’s firepower.

“Cao Zhixue, I advise you to really think about it, whether you want to go this way in the future. I call you up to answer questions, right? Everyone can answer more or less, how about you? You haven’t done it once. Answered it.”

Cao Zhixue’s neck was red because of his spray. Young people at this age want face the most. Usually in the class, physics is always one of the best, and he often takes the top ten in his grade.

Besides, he came from an ordinary class, and the head teacher and physics teacher have always looked at him with the eyes of top students.

Where has it been hit?

He flushed, clenched his fists tightly, and lowered his head, his aura seemed to be consumed by most.

Even he himself began to wonder whether he was studying physics at all?

Is he really too stupid?

At this time, Chen Jun, one of the three fools, couldn’t stand it anymore, and stood up awkwardly.

Speaking quite politely: “Teacher, according to the scope of the competition in previous years, Coriolis force should not be tested for derivation, but only for direction judgment and some applications?”

It’s really unnecessary to die in this place. If you really want to explore the principle and deduction, somehow give them some time to consolidate it?

Lin Ping was smiling and looked at him: “Are you a teacher or am I a teacher? Do you need to teach me what to learn and what not to learn?”

Chen Jun was completely angry by him, and the backlog of dissatisfaction broke out for many days: “Lin Pingzheng, you don’t know how to teach at all. Don’t look down on people because you are a big B. If you teach like this, who the **** can listen. Got to understand?”

Lin Pingzheng didn’t expect that he would be so tough, and his temper came up. He said a lot of things that he usually hid in his heart, but he wouldn’t be able to say things in public: “Wang Jing is originally a talented person who can read it. I will tell you today. You, I got a big B with the gold medal in the physics competition. I am really amazing. If I don’t understand, I admit that I have a low IQ. There are some things that I can’t just force.”

Chen Jun choked, but he was strong, and he had nothing to refute.

“Fuck, I quit.”

He was so angry that he threw his pen, put the book and notebook away, and walked to the podium to talk to Cao Zhixue.

This big idiot was scolded like a wood.

Cao Zhixue was pulled down from the podium by him. Even Deng Nian, the calmest of the three fools, didn’t persuade him this time. He followed the two buddies to clean up and plan to leave.

At the end of the evening self-study get out of class, the students in other classes came to watch the excitement when they heard the movement.

When everyone heard about the small black house of the sports competition class, it seemed that the coach and the students were arguing. The high school students who were already bored and boring became interested in an instant.

Lin Pingzheng was already too arrogant. When he heard someone was leaving, he immediately sneered and released the pointer: “Okay, you three should withdraw from the sports competition class today. Don’t come back to participate in the competition. Go for the college entrance examination. .”

Chen Jun looked back: “If you don’t participate, you won’t participate. The competition is great.”

With that said, his momentum is still a bit low, and he also knows that he may not be able to end if he walks in a desperate way, but the blood has already been on his mind, and he can’t take care of so much.

The classmates who watched the excitement around probably understood what was going on and started to talk.

Some people look down upon Lin Pingzheng’s deeds: “Damn, this coach is really awesome, is he so arrogant? I really think I’m a big B?”

But after all, it is a key high school, and there is always an inexplicable awe for people who come out of the top 2 universities in China, so there are people who speak for him.

“B is big, they have a bit of capital, maybe they are young and vigorous.”

“You know what a fart, I heard Jin Ming said that this teacher doesn’t do personnel affairs at all, and the lectures are so bad that he feels that he is awesome every day.”

“That’s no way, our director Liu Zhijun can’t do the competition questions at all, we still have to rely on others.”

Zhang Man sighed inwardly when he saw this scene.

The three of them were about to go away with their necks. Lin Ping was standing on the podium with flames in his eyes.

What is this called?

She intends to persuade both sides to calm down, so even if she has breath in her heart, her tone is still objective and calm: “Mr. Lin asked us to do the derivation, maybe there is his reason.”

——”But, do you have too little time for us? I have read Cao Zhixue’s workbook, and you said he can’t do every question, but he is not. In my opinion, he is very smart My child…Students, as long as you go back and read the notes carefully, you can basically master it. The problem-solving ideas are clear and your mind can be turned quickly. I think you ask us to do the problem every time you finish the class. Reasonable. This will not only fail to achieve the purpose of consolidating knowledge, but will also seriously dampen the enthusiasm of students. Not only will it not play a positive role in teaching, it will also cause serious resistance to students. I hope you can change the teaching slightly mode.”

Her speech speed is not fast or slow, but a little oppressive. There is no other way. I have been a high school physics teacher for many years. When I talk about education, my “teacher voice” comes out naturally.

Although she was not able to teach competitions in her previous life, she did very well in her physics class, but she was rated as an outstanding young teacher for several years.

Lin Ping was very angry and couldn’t hear the words at all. What’s more, Zhang Man was a poor student in his eyes, and a little girl with little knowledge.

Talking to him about teaching methods?

“Zhang Man, right? Don’t think I didn’t say you, you are fine. I have read your transcript. When I first entered high school, did I fail the physics exam? Yes, the physics in the first semester of high school is simple , You girls, you can make up for it with a little hard work, but don’t underestimate the competition. Competition is not something that can make up for one’s weaknesses with diligence. IQ is a tough hurdle.”

As he said, his anger got up completely, and he began to speak without a word: “I will open up and say today, as far as the IQ of these classmates in your class, you should stop doing physics as soon as possible. You are insulting the word’physics’ .”

As soon as Cao Zhixue heard Goddess Zhang speak for her, he was so touched. At this moment, Lin Ping was so frustrated with her that he wanted to rush up after he fell.

His eyes were red with anger.

But he just wanted to go up, but he was caught by someone reaching out.

When he turned his head, the big man who had been silent was sitting quietly, pulling him with one hand, making him unable to break free.

The young man leaned back irregularly, and a smile suddenly appeared at the corner of his mouth. In his dark eyes, there was a haze that he had never seen before, and he stared straight at Lin Ping.

He was obviously smiling, but Cao Zhixue had goose bumps, and his arrogance of rising up and attacking him immediately stunned.

This old man thought he was scarier when he was usually expressionless, but he didn’t expect to smile even more scary.

Moreover, he was obviously sitting, but seeing Lin Pingzheng’s eyes, how could he be so condescending?

Everyone was looking at the teenager, only to hear him chuckle, and then asked, “Physics?”

——”Do you know what physics is?”
