I just want to be a quiet scholar

Chapter 78 Conservative, Radical

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

"I just listened to two questions, it's a bit low." Shen Qi answered.

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

Shen Qi said: "Just say the submarine problem written on the blackboard, because the inlet and outlet areas are the same, so the flow rate remains unchanged, the effect of the ampere force is to increase the pressure, and then considering the conservation of energy, find the difference between v1 and v2. It requires too much calculation. It's too simple, CMO is more than eight streets more difficult than CPhO. Mr. Mu, I have no other intentions, nor am I arrogant, anyway, I am very sad 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? Isn't our school's sports team so bad?"

"Shen Qi, let me tell you, the CPhO preliminary round is at this level. The first question just now is the real question of the CPhO preliminary round, 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 competition of the mathematics league, which is equivalent to the national preliminary competition of CPhO. At that time, his mathematics level was level 3, and it was only after three layers of skin were removed that he won the mathematics league. Provincial Champion.

Now Shen Qi's physics level is also level 3, and the questions in the CPhO national preliminary round are like pediatrics to him. He can figure out the answer without much effort.

"The sense of superiority that mathematics gives you is really unparalleled. I would like to extend a friendly invitation to you on behalf of the competition team. Come in and learn from each other?" Teacher Mu opened his bows from left to right and snapped his fingers two crisply, snapping.

"Okay." Shen Qi snapped his fingers with his right hand, snapped, and snapped his fingers with his left hand, but didn't snap.

"You're 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, motioning for Shen Qi to follow her into the laboratory.

"Physics teachers really have 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 Wushu team were ignorant. They all knew Shen Qi, and the math boss came to our Wushu team to smash the field?

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

clap clap clap!
applause.

"Hey, Shen Qi is here to smash the scene, why should we applaud?"

"Could it be a friendly match?"

The players were talking.

"Need to introduce myself, Shen Qi?" Teacher Mu asked Shen Qi next to him.

Shen Qi asked more than a dozen sports players in the audience: "Do you need it?"

"No no no."

"Everyone knows everything."

The players all shook their heads.

Shen Qi said: "Hello everyone, then I won't say more, everything will be kept silent."

Teacher Mu said to Shen Qi, "Go down and find a seat 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, "Visiting each other and having friendly exchanges. Keep talking, Lin Xingyu, Mr. Mu is ready to make a big move."

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

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

brush!
Swipe!

The players in the audience raised their hands.

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

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

Mr. 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 Mr. Mu been in the competition team?"

Lin Xingyu: "I came here not long ago, just before the Spring Festival. She took us to a training class before the Spring Festival, and then she went on vacation."

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

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

Teacher Yue is nearly 60 years old and is about to retire. He is a senior teacher in Nangang No. [-] 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 admiringly.

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

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

"Oh yes, so condescending? What kind of doctor?" Shen Qi glanced at Teacher Mu, who was operating the multimedia system. She was also a doctor of physics?

"Astrophysics, studying the universe." Lin Xingyu didn't want what Teacher Mu admired.

"It's amazing, Master Mu." Shen Qi's understanding of Teacher Mu was further deepened. The female doctor who studied astrophysics was living in a folk middle school and gave low questions. What hidden 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, go back to your seat."

According to Shen Qi's preliminary observation, the overall strength of this school competition 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 is preliminaries, semi-finals, and national finals, which are similar to CMOs. 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 Mr. Mu's operation, a screen slowly fell in front of the laboratory, and an animation demonstration was projected on the screen.

In the center of the picture is a small red ball, marked with a black English letter H.

Obviously, this little ball represents hydrogen atoms.

At each end of the hydrogen atom, there is a strangely shaped transmitter, zizi, the transmitter continuously shoots blue rays, attacking the red hydrogen atoms.

Kaka.

The multimedia speaker emits the sound of objects freezing and cooling.

The red spheres representing the hydrogen atoms gradually changed color, and the spheres became lighter in color, eventually turning light blue.

The demo animation ends here.

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

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

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

"Let's demonstrate it again, Mr. Mu." The students in the audience suggested one after another.

"Okay, do it again." Teacher Mu replayed the animation of the laser cooling of atoms.

In this demonstration, Mr. Mu explained simultaneously: "Laser cooling is a technology that uses the interaction between laser light and atoms to slow down the motion of atoms to obtain ultra-low temperature atoms. Few countries in the world have mastered this technology, among which the United States is in the lead. China is also catching up. Chinese scientist Mr. Steven Chu won the Nobel Prize in Physics in 97 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 frame displayed on the screen, due to the recoil effect, there is a minimum temperature. Please calculate this minimum value." Teacher Mu finished the second animation 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 difficult at the preliminary level of the physics competition. Now it has been directly raised to the level of the Nobel Prize in Physics. Teacher Mu is very conservative. .
