didn't wait for the next morning, just over half an hour later, Xu Chuan wrote out the answer.

The amazing speed of solving the problem made Xu Chenghu, who received the answer, stare at him suspiciously.

This question is made by him himself, and the difficulty is quite large, it is a combination of high school physics and college physics, and the college physics knowledge required to solve it is quite a lot, not to mention high school students, even if the graduate students of the physics department come and want to solve it smoothly.

Soon, however, the solution on the manuscript paper took away his attention.

"Solution: 1. At the temperature T, the average kinetic energy of the atom is Ek = 3/2 kbT = 1/2 mμ², and the μ is the rmf rate. μ = √3 kbT/m and kinetic energy p = √3 kbTm, from which the De Broglie wavelength can be interpreted as λdь = h/p = h/√3 kbTm. ”

"2. The density number of particles is n=N/V, where N is the total number of particles and V is the volume; Average volume of particles........"

"III."

A complete answer came into Xu Cheng's eyes, and compared with the title, the length of the manuscript paper occupied by the answer was not large.

But it was this simple answer that made Xu Cheng's mouth open wide.

He never thought that this question could be solved in this way, starting from the average kinetic energy of the atom, then finding the rms rate, then turning to kinetic energy, and then finding the de Broglie wavelength.

In the third question, the rewriting of the equation between the average number of particles and the relationship between particles is the soul of the soul.

This step directly narrows down the solution to the density of ordinary gases at room temperature to less than four steps, which is simply incredible.

"How did you come up with this step?"

After reading the answer, Xu Cheng took a deep breath, suppressed the surprise and shock in his heart, and pointed to the steps to rewrite the equation and asked.

This stroke is like a stroke of genius, and he, a physics teacher who has led the provincial training team for many years, never thought that he could solve it like this.

"It's very simple, starting from the field kinetic energy, combining the Abelian group and Maxwell's velocity distribution function, you can directly turn the rmf rate to kinetic energy, and the subsequent particle equation can be rewritten with vertex equations and differential equations."

Glancing at the place where Xu Cheng was pointing, Xu Chuan explained with a smile.

"You came up with all of this yourself?" After listening to the explanation, Xu Cheng asked in a daze.

Xu Chuan nodded in affirmation.

These things were indeed all thought up by himself, but they belonged to the knowledge before rebirth, and belonged to some mathematical knowledge that he learned in passing when studying physics.

"The afterlife is terrible, the afterlife is terrifying."

Xu Cheng sighed, and continued: "This kind of problem-solving ideas and methods, have you ever thought about sorting out and writing a paper and sending it out?" ”

"Submit papers?"

Hearing this, Xu Chuan was stunned for a moment.

Although he was familiar with the matter of submitting essays, he had never thought about it when he started submitting essays in high school.

"Yes, when calculating the functional relationship between the typical distance l between particles of Bose Einstein condensation phenomenon l and the density of particle number n, as well as the density of ordinary gases, your way of solving the problem is already a new method, and you can write a paper, I believe many journals will accept it."

"Of course, I'm not sure if there is such a way in the physics world for the time being, I will check it out when I go back, if there is really no such method, then you can sort it out and write a paper."

"However, the domestic flagpole is relatively mixed, "Physica Sinica" or "Physics" can vote for it, and I recommend that you vote for the foreign "Progress in Physics".

"Advances in Physics mainly publishes condensed matter physics and statistical mechanics, and this question and the method you use just fall within the scope of submission, if you can successfully submit, it will be of great help to you in the future."

"You haven't submitted a paper yet, have you? In this way, the sample essay and writing standards, you wait for my office, I will teach you. ”

"After writing it, you decide which one to vote for, and I'll help you revise and polish it."

Xu Cheng said with a smile, the talent and knowledge of the student in front of him are really amazing.

"I'll go back and check first, you can prepare well, and you can put the training matter aside first."

Xu Cheng patted Xu Chuan on the shoulder, turned around and walked out of the classroom, and went to check the relevant information.

He has seen a lot of students who have enough college knowledge in high school, but he has seen the first one who can flexibly use and even find a new and unprecedented way to solve problems.

The most commendable thing about academics is to have their own thoughts.

This new method and idea of solving the Bose Einstein condensation phenomenon is enough to write a paper.

That is, he is the one who leads the team this year, and if it were other high school teachers, there would probably not be this idea of letting high school students vote for SCI.

Although the level of this new method is a little lower, and "Progress in Physics" may not be included, if you are lucky enough to accept it, it will definitely be of great help to Xu Chuan.

Not to mention domestic schools, even the top physics universities abroad, whether it is Princeton or Harvard, or MIT and Stanford University, will not refuse a student who can give top SCI in high school.

They would even send him an invitation to go to college.

Xu Cheng didn't expect Xu Chuan's mathematical ability to be so amazing, maybe he really hopes to get him back from IMO next year.

If he can win a gold medal at IMO and a gold medal at IPHO, then Huaguo will have the first double gold medalist in the same year.

Even if this achievement is put into the whole world, there are no more than three people who have obtained it, and there are no more than three people in China at present.

Not to mention that they won both IMO and IPHO gold medals in the same year, even students who won both IMO and IPHO gold medals are not available in Huaguo.

Although physics and mathematics are not separated, the gap between the two is still quite large.

......

As soon as Xu Cheng left, the classroom became lively, and everyone eating melons on the side came over one after another.

"Brother Chuan, what is the paper? Advanced Essay? "This is a scumbag in the first year of high school who is expressing his doubts.

"Don't make a fuss, the composition is compared to the paper, and you don't even deserve to mention the shoes!"

"Generally speaking, only after graduating from college, you need to write a graduation thesis, and graduate students will publish academic papers.

"Progress in Physics, I know, this is the world's top journal, if you can publish a paper on it, you can go directly to the university to become a professor!"

"Damn, go straight to the university to be a professor? Brother Chuan is awesome! ”

"What's your name, Brother Chuan! In the future, I have to call it Kawajin! ”

"The god of Sichuan is awesome!"

The swarming of students and all kinds of boasting and rainbow farts made Xu Chuan cry and laugh, but this feeling seems to be quite good?
