I Just Want to Be a Quiet Top Student

"How long have you been listening?" Teacher Mu asked.

"I only listened to two questions, a little low." Shen Qi replied.

Teacher Mu smiled without being angry: "Really?"

Shen Qi said: "For the submarine problem written on the blackboard, because the area of ​​the inlet and outlet is the same, the velocity of the flow remains unchanged, and the effect of the Ampere force is to increase the pressure. Considering the conservation of energy, find out the difference between v1 and v2. It requires too much calculation. This is too simple, and CMO is more than eight blocks more difficult than CPhO. Mr. Mu, I have no other meaning, and I am not arrogant. Anyway, I am very worried when I see those low questions."

(CPhO: National Physics Competition for Middle School Students)

"The two questions you saw just now are really low." Teacher Mu continued to smile.

Shen Qi was speechless: "This... low, you still write it out for them to do? Our school's sports team isn't so bad, is it?"

"Shen Qi, let me tell you that the CPhO preliminary round is at this level. The first question just now is the real CPhO preliminary round question, and the second question can almost be included in the CPhO preliminary round question bank."

"Then the CPhO preliminary competition is of the nature of participation by the whole people?" Last year, Shen Qi participated in the provincial math league competition, which was equivalent to the CPhO national preliminary competition. Provincial champion.

Now Shen Qi's physics level is also level 3, and the questions of the CPhO National Preliminary Competition are like pediatrics to him, and he can calculate the answer with mental arithmetic without any effort.

"Mathematics gives you an unparalleled sense of superiority. On behalf of the Wujing team, I would like to extend a friendly invitation to you to come in and learn from each other?" Teacher Mu snapped his fingers two times in succession, clapping.

"Okay." Shen Qi snapped his fingers with his right hand, snapped, and snapped his fingers with his left hand again, no snap.

"You are not left-handed, you need to practice more." Teacher Mu snapped his fingers with his left hand, like setting off firecrackers, and then made a gesture to signal Shen Qi to follow her into the laboratory.

"The physics teacher really has a lot of unique skills." Shen Qi followed Teacher Mu into the room.

As soon as the two entered the door, more than a dozen members of the Wujing team were confused. They all knew Shen Qi. The math boss came to our Wujing team to mess up the game?

"Let me tell you something." Teacher Mu said to all the team members, then glanced at Shen Qi: "This is Shen Qi, welcome everyone."

Clap clap!

applause.

"Hey, Shen Qi came to mess things up, why should we applaud?"

"Maybe it's a friendly match?"

The team members talked a lot.

"Do you need to introduce yourself, Shen Qi?" Teacher Mu asked Shen Qi beside him.

Shen Qi asked the dozen or so Wujing players in the audience: "Do you need it?"

"No no no."

"I understand everything."

The players all shook their heads and waved their hands.

Shen Qi said: "Hello everyone, then I won't say much, everything is in the air."

Teacher Mu said to Shen Qi: "Go down and find a seat."

Shen Qi walked to the seat next to Lin Xingyu and sat down.

"Boss, what's the situation?" Lin Xingyu asked impatiently.

Shen Qi said with a smile: "Visit each other and communicate with each other. Lin Xingyu is holding back his words, Teacher Mu is going to make a big move."

Lin Xingyu looked at the blackboard suspiciously, not knowing what happened.

Teacher Mu tapped on the blackboard: "Which student came up with the answer to this submarine question?"

brush!

Brush!

The players in the audience raised their hands one after another.

"It seems that there are no obstacles for you in the CPhO preliminary competition questions. Maybe my teaching is too conservative." Teacher Mu looked at Qiqi's raised arms and said, "Bai Lingye, come on stage and give the answer."

A boy came to the stage and wrote his solution process on the blackboard.

Teacher Mu walked to the multimedia console on the side of the blackboard, turned on the power, and operated the multimedia teaching system.

During the waiting time, Shen Qi asked Lin Xingyu: "How long has Teacher Mu been in the Wujing team?"

Lin Xingyu: "Not long ago, she came here before the Spring Festival. She took us a training class before the Spring Festival, and then she was on vacation."

"I remember that the Wujing team was led by Teacher Yue?" Shen Qi asked.

"Ms. Yue suffered a cerebral hemorrhage and was hospitalized." Lin Xingyu showed a terrifying expression.

Teacher Yue is close to sixty years old and is about to retire. He is a senior teacher at Nangang No. 2 Middle School. Shen Qi also felt terrible: "This... you group of incompetent guys, made Teacher Yue angry and had a cerebral hemorrhage. So before there was a full handover, Teacher Mu rushed to work. She gave you such a simple problem to do, and she was trying to figure it out. ?”

"Perhaps, but Teacher Mu is very knowledgeable and powerful." Lin Xingyu said adoringly.

"She has only taught you for one and a half training sessions, so she is already learned? Is she really good?" Shen Qi asked back.

"She's a female Ph.D. in physics." Lin Xingyu's eyes were full of little stars.

"Oh, is it so hanging? Which direction is the doctor?" Shen Qi glanced at Teacher Mu who was operating the multimedia system. She is still a doctor of physics?

"Astrophysics, the study of the universe." Lin Xingyu admired Teacher Mu more than anything.

"Amazing, Master Mu." Shen Qi's understanding of Teacher Mu has deepened further, and a female Ph.D. who studies astrophysics has been living in a private middle school to answer low questions. What secrets are hidden behind this?

At this time, the boys on the stage finished their answers, and Teacher Mu said, "That's right, you're all right, Bai Lingye, go back to your seat."

According to Shen Qi's initial observation, the overall strength of this school sports team is not bad, at least Lin Xingyu and Bai Lingye have the strength to advance to the national semi-finals. The competition system of CPhO consists of preliminary rounds, semi-finals, and national finals. It is similar to CMO. After several rounds of tests, the best players will be selected to enter the national team and participate in IPhO.

"Students, please watch the big screen carefully." Under the operation of Teacher Mu, a screen slowly fell in front of the laboratory, and an animation demonstration was projected on the screen.

In the middle of the screen is a small red ball with a black English letter H marked on it.

Obviously, this small ball represents a hydrogen atom.

There is a strange emitter at each end of the hydrogen atom, and the emitter continuously emits blue rays to attack the red hydrogen atom.

Kaka.

The multimedia speakers emit the sound effect of objects solidifying and cooling.

The red spheres representing hydrogen atoms gradually change color, the spheres become lighter and lighter, and finally turn light blue.

The demo animation ends here.

Including Shen Qi, all the students in the audience watched with gusto.

Only a very small number of cutting-edge scientific researchers in the world can personally participate in micro-experiments at the atomic level, and most of them rely on teaching materials or science fiction films.

"What I'm demonstrating to you is the laser cooling of atoms, do you understand?" Teacher Mu asked.

"Demonstrate it again, Mr. Mu." The students in the audience suggested one after another.

"Okay, let's do it again." Teacher Mu replayed the atomic laser cooling demonstration animation.

In this demonstration, Mr. Mu explained simultaneously: "Laser cooling is a technology that uses the interaction between laser and atoms to slow down the movement of atoms to obtain ultra-low temperature atoms. A few countries in the world have mastered this technology, and the United States is in the lead. China is also catching up. Chinese scientist Mr. Steven Chu won the 1997 Nobel Prize in Physics for his theoretical research on this technology, and he was hired as a foreign academician of the Chinese Academy of Sciences.”

"Then my question is, in the atomic reference system shown on the screen, due to the recoil effect, there is a minimum value of temperature. Please calculate this minimum value." Teacher Mu finished the second animation display and released a new picture, which is A schematic diagram of a planar atomic reference frame.

"This..." The students in the audience were stunned. Just now, it was obviously the difficulty of the preliminary level of the physics competition. Now it has been directly promoted to the level of the Nobel Prize in Physics. Teacher Mu is very conservative. If he is radical, he will go to heaven. .
