I Just Want to Be a Quiet Top Student

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

　　 "I heard two questions, it was a bit low." Shen Qi answered.

　　 Teacher Mu smiled and didn't get angry: "Really?"

Shen Qi said: "Just say the submarine question written on the blackboard, because the entrance and exit area is the same, so the flow rate is the same, the effect of ampere force is to increase the pressure, and considering the conservation of energy, find the difference between v1 and v2. It requires too much calculation. This is too simple. CMO is more difficult than CPhO. Teacher Mu, I have no other meaning, nor arrogance. Anyway, I am particularly worried when I see those very low topics."

　　 (CPhO: National Physics Competition for Middle School Students)

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

　　 Shen Qi was speechless: "This...low, you still write it down for them? Our school sports team is not so bad, right?"

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

"Then the CPhO preliminary contest belongs to the nature of national participation?" Last year, Shen Qi participated in the provincial competition of the Math League, which was equivalent to the national preliminary contest of CPhO. At that time, his math level was level 3, and that was only after removing three layers of skin to get the number league. Provincial champion.

　　 Now Shen Qi's physics level is also level 3. The CPhO national preliminary contest questions are like pediatrics to him, and he can calculate the answer without any effort.

　　 "The superiority that mathematics gives you is really unparalleled. On behalf of the sports team, I would like to extend a friendly invitation to you to go in and learn from each other?" Teacher Mu opened the bow left and right and hit two crisp fingers, snapping.

　　 "Okay." Shen Qi snapped his right hand and snapped, and snapped 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, as if setting off firecrackers, and then made a gesture to signal Shen Qi to follow her into the laboratory.

　　 "The physics teacher has so many unique skills." Shen Qi followed Teacher Mu into the room.

　　 As soon as the two entered the door, more than a dozen players from the sports team were unidentified. They all knew Shen Qi. Did the math boss run our sports team to hit the field?

　　 "I have something to say." Teacher Mu said to all the team members, and then glanced at Shen Qi: "This is Shen Qi, everyone welcomes it."

　　 Happiness!

applause.

　　 "Hey, Shen Qi came to hit the scene, why should we applaud and welcome?"

　　 "Maybe it's also a friendly match?"

　　 The players 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 players in the competition: "Need it?"

　　 "No, no, no."

　　 "Everybody understands everything."

　　The players all shook their heads and waved their hands.

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

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

　　 Shen Qi walked to the seat next to Lin Xingyu and took a seat.

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

　　Shen Qi smiled and said: "Visit each other and communicate friendly. Lin Xingyu is holding back, Teacher Mu is ready to zoom in on the move."

　　 Lin Xingyu looked suspiciously at the blackboard, not sure what was going on.

　　 Teacher Mu knocked on the blackboard: "Which student got the answer to this submarine question?"

brush!

　　 Brush!

　　The offstage players raised their hands.

　　 "It seems that there is no obstacle for you in the CPhO preliminary contest. Maybe my teaching is too conservative." Teacher Mu looked at Qi Qi's raised arms and said: "Bai Lingye, you will come on stage to give the answer."

　　 A boy came on stage and wrote his answering 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.

　　While waiting, Shen Qi asked Lin Xingyu: "How long has Mr. Mu come to the game team?"

　　 Lin Xingyu: "I just came, just before the Spring Festival, she took us a training class before the Spring Festival, and then it was off."

　　 "I remember that the game team was brought by Teacher Yue before?" Shen Qi asked.

　　 "Mr. Yue had a brain hemorrhage and was hospitalized." Lin Xingyu showed a terrible expression.

　　Mr. Yue is about to retire at the age of sixty and is a senior teacher in Nangang No. 2 Middle School. Shen Qi also felt terrible: "This...you group of incompetent guys have caused Teacher Yue to have a cerebral hemorrhage. So before the handover was complete, Teacher Mu rushed to work. She gave you such a simple topic to figure out the bottom line. ?"

　　 "Perhaps, but Teacher Mu is very knowledgeable and very good." Lin Xingyu admired and said.

　　 "She has only taken you one and a half training sessions, so she has knowledge? Is she really good?" Shen Qi asked back.

　　 "She is a female doctor of physics." Lin Xingyu's eyes were full of small stars.

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

　　 "Astrophysics, the study of the universe." Lin Xingyu did not want to be admired by Teacher Mu.

　　 "Awesome, Master Mu." Shen Qi furthered his understanding of Teacher Mu. The female doctor of astrophysics who was studying astrophysics left the folk middle school and asked low questions. What secrets are hidden behind this?

　　 At this time, the boy on the stage completed the answer, and Teacher Mu said: "Yes, all right, Bai Lingye, please go back to your seat."

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

　　 "Please look at 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 center of the screen is a small red ball with a black English letter H on it.

　　 Obviously, this small ball represents the hydrogen atom.

　　 There is a strangely shaped emitter on each end of the hydrogen atom~www.readwn.com~Zizi, the emitter constantly shoots blue rays to attack the red hydrogen atom.

　　 Click.

　　Multimedia speakers emit the sound effect of solidification and cooling of objects.

　　 The red ball representing the hydrogen atom gradually changes color, the color of the sphere becomes lighter and lighter, and finally turns to light blue.

　　The demo animation is over here.

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

　　 There are only a handful of cutting-edge scientific researchers in the world who can personally participate in microscopic experiments at the atomic level, and most of them rely on teaching materials or science fiction films.

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

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

　　 "Okay, do it again." Teacher Mu replayed the atomic laser cooling demo 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 motion 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. The Chinese scientist Diwen Zhu won the Nobel Prize in Physics in 1997 for his theoretical research on this technology. He was hired as a foreign academician of the Chinese Academy of Sciences."

"Then my question is, in the atomic reference system displayed on the screen, due to the recoil effect, the temperature has a minimum value. Please calculate this minimum value." Teacher Mu ended the second animation presentation and released a new picture. A schematic diagram of a plane atomic reference system.

"This..." The students in the audience were stunned. It was clearly the difficulty of the preliminary level of the physics competition. Now it is directly promoted to the level of the Nobel Prize in Physics. Teacher Mu is very conservative. Once radicalized, he will go to heaven. .
