I Just Want to Be a Quiet Top Student

When the light shines on the charge to cause the charge to oscillate, a driving force is generated in the direction of the beam, that is, radiation pressure or light pressure.

The momentum generated by each absorption and radiation of the atom can be obtained as:

2\u003c△p^2\u003e=2^2*ω0^2/c^2

Then the total momentum change in time t is:

2\u003c△p^2\u003e

Therefore, the cooling momentum of the atom changes as:

p0^2=12\u003c△p^2\u003eγpm/(2β)=3 mγ[2∣δ∣/γ+γ/2∣δ∣]/4

The propulsion momentum transmitted by light per second is equal to 1/c multiplied by the energy absorbed from light per second, that is, the momentum transmitted by light is always:

Shen Qi filled the left blackboard with his writing, and he also wrote a small part of the right blackboard, with one piece of chalk broken.

The laboratory is quiet enough to listen to needles, and Teacher Mu and other team members are watching Shen Qi's performance.

Shen Qi's personal experience when he participated in the mathematics competition last year was that it is OK to compete at the provincial level at the third level.

Mathematics at level 6 has a certain real bonus to physics at lower levels, the system is set like this. Under the care of his math father, Shen Qi's actual physical combat ability has increased compared to his current level.

If this is a physical symphony, Shen Qi's performance up front is great, at least it looks like that.

A majestic movement with an elegant ending is perfect. After deriving and explaining on a blackboard, Shen Qi gave the answer. The minimum temperature value is:

Tmin=2.4*10^-4K

That is 2.4 times 10 to the negative fourth power Kelvin, which is a value very close to absolute zero.

"The solution is complete." Shen Qi put half of the chalk into the slot, and patted the chalk dust on his hands.

Pa, Teacher Mu habitually snapped his fingers: "The answer is correct, smart."

"Mr. Mu, only in the laboratory can you see the negative fourth power of 2.4 times 10?" Shen Qi and Teacher Mu exchanged ideas.

Teacher Mu said: "In 1985, Mr. Zhu successfully completed the laser cooling experiment of atoms. PicoKelvin-level cooling, that is, the order of one trillionth of a degree above absolute zero. Applied physics is developing rapidly, but theoretical physics is the basic support." She also has idols, and those physics experts are her idols.

"Physics is true, right?" Shen Qi asked again.

Teacher Mu was very firm: "Of course!"

"After a long time, Mr. Mu quoted Mr. Zhu's experimental case." Shen Qi turned around and glanced at the blackboard. It was interesting, and physics was actually interesting.

Teacher Mu said with a smile: "When it comes to the national finals or international competitions, those teachers who write the questions are very keen to adapt the previous years' Nobel Prize in Physics cases. There is no harm in broadening your horizons, isn't it?"

"Indeed." Shen Qi nodded.

Mr. Mu, Mr. Shen Qi and Mr. Shen Qi had questions and answers, chatted and laughed happily, and the dozen or so members of the competition team in the audience were dumbfounded.

"Why is Shen Qi's physics so strong?

"Could it be that what we have learned is fake physics?"

"I can't afford it."

"It's so annoying."

"Boss."

"Absolute boss."

"My material competition team Jiangshan is gone..."

There was wailing in the audience, but all the team members admired Shen Qi very much. This kind of mood was more complicated, and it was difficult to express it in words.

"I'm asking for advice." Shen Qi bowed his hands respectfully to Teacher Mu.

"Excuse me." Shen Qi cupped his fists towards the dozen or so Wu Jing team members in the audience, then turned and left.

"Hey, Shen Qi!" Teacher Mu chased him out.

The team members stared wide-eyed: "Ten steps to kill one person, a thousand miles will never stop!"

"Flick off your clothes when it's over, and hide your achievements and fame!"

"My singing moon wanders, my dancing shadow is chaotic!"

"Changing wind for tens of thousands of miles, blowing across Yumen Pass!"

"There is a character in the Second Middle School, the boss' name is Shen Qi!"

"Run after pretending, it's so exciting!"

The physical competition team members in the laboratory had an uproar.

"Caught off guard, our Wujing team are all honest and responsible people, and we attend classes well, we don't recruit anyone or offend anyone, Shen Qi, when you rushed in, you were shot by light waves, why on earth!"

"Shen Qi, where do you think our Wujing team is, you come and leave whenever you want?"

"Bai Lingye, you bastard, Shen Qi has left and you are beeping, you have the guts to be anal just now!"

"What the hell am I... What's wrong with my anus?"

Suddenly, someone felt that something was wrong: "On the fifth day of the first month of Chinese New Year, Shen Qi didn't come early or late, why did he come at this time? There must be a mole in our team! Lin Xingyu, tell me, are you a mole? You brought the devil into the village?"

"Yes, it must be Lin Xingyu. Shen Qi was sitting next to him just now, and he is quite familiar with him!"

"Comrades, please don't misunderstand me. I can be regarded as an old player when I joined the team in my first year of high school. I am extremely loyal to the Wujing team!" Put the paper away, this is the boss's manuscript, take it with you to increase your combat power.

Outside the laboratory, Teacher Mu caught up with Shen Qi and asked, "Hey, are you leaving now?"

Shen Qi said: "Today, on the fifth day of the lunar new year, I have to go to my uncle's house for lunch. His house is quite far away."

"Visiting relatives is a must. It's human nature. By the way, Shen Qi, are you still participating in this year's math competition?" Teacher Mu asked.

Shen Qi shook his head: "I'm not going to participate, I've got everything I need. In the next few months, I won't spend more than two hours a day on mathematics. It's very necessary to consolidate and sort out. Appropriate stays are for greater strides in the future.”

"Idle is also idle, come to Wujing team to play?" Teacher Mu is eager for talent.

Shen Qi was noncommittal: "Think about it."

"Come on, the physics competition will start at the end of March, the preliminary round." Teacher Mu is eager for reinforcements.

"By the way, Mr. Mu, where did you get your PhD?" Shen Qi changed the subject.

Teacher Mu: "Department of Physics, Yanda University."

"This... so it's Senior Sister Mu!" Shen Qi was a little surprised, "Sister, you are a female Ph.D. student from the Physics Department of Yanda University. Why do you come to our school to be a teacher?"

"Is our school very bad? The city's key high schools are good. Now our school recruits teachers, starting with a master's degree, and there is no upper limit. Hey, don't ask me, just say a word, come to the Wujing team, junior?"

"If you are Teacher Mu, then I will consider it. If you are Sister Mu, then I will not consider it. Come on."

So Shen Qi became a member of the physics competition team of Nangang No. 2 Middle School.

In the nearly 100-year history of Nangang No. 2 Middle School, of course there have been students who have participated in more than one subject competition, but there have never been students who have won the highest awards in different subject competitions.

While talking and laughing, Shen Qi joined the Nangang No. 2 Middle School Physical Competition Team. Even if he pretended to be in the sky, he would be able to win awards in two subject competitions at most in his high school career.

There is not much time left for Shen Qi.
