Chapter 421: He's Professor Xu Mang (2/3)
To solve the problem of multiple particles in atoms, Xu Mang knows that there is a method called Self-Consistent, an equivalent average field, which for one electron can be considered to be moving in a force field, which is the average effect of other electrons and nuclei on it.
Thinking of this, Xu Mang silently walked up to the stage, stood in front of the blackboard and picked up the chalk, and began to solve the problem of multiple particles in the atom, and the approximate method, after assuming the approximate electron wave function product of the ground state wave function of the atom, Xu Mang obtained the expression equation of the Hamiltonl quantity.
The latter problem is solved by the emergence of the equation, and the extreme value of H is found under the condition of normalization... And then there's endless calculations.
At this point,
The students in the audience were going crazy, looking at the back of the boy in front of the blackboard, and the equations and equations written in the chalk in his hand, he was actually solving the problem raised by the professor, and he looked like it.
"Oh my God... How did he do it?" a student looked at the blackboard with ever-increasing contents, and the bewildering complexity of the equation process made people feel suffocating horror, is this a student?
That's it, Professor, right?
Professor Jeff stood on the side, watching Xu Mang show his skills to the fullest, showing a smile, fortunately he found Professor Xu Mang in advance, good guy... Such a cow man is actually hiding in the student group, and I don't know what he thinks.
The calculations continue,
Soon Xu Mang finished the contents of a blackboard, he moved the top board down, and continued to calculate.
But...
With the continuous increase of content, the students below are about to collapse, and their minds can no longer keep up with the calculation process of this great god, and his calculation speed is too fast to keep up with the updated content.
"Danny... You're the best of us, how do you think you compare to him?" a girl asked the long-haired boy next to her, "And what level has this guy reached?"
"I'm sorry. ”
"Yarman... I was so vulnerable in front of him. When the long-haired boy saw the young man on the stage, and then looked at the calculations written on the blackboard, he was immediately overwhelmed with great frustration, he was already on the verge of autism.
In high school, Danny showed extraordinary talent in physics and mathematics, and the local media also reported wildly, and then successfully enrolled in Columbia University to major in physics, and with his strong talent, he quickly established himself among freshmen.
But... Today I met a non-human creature that looked like a human.
"His talent for math terrifies me...", Danny said seriously, "There's something in it, I've even come across it for the first time, I can't imagine how he can do it so quickly, I think... There is only one existence!"
"What exists?" asked the girl next to her.
"This guy... Not a normal person. Danny smiled helplessly: "A neurotic that has not yet been cured, you can only do it in a fantasy of imagination, otherwise... I can't think of a second possibility. ”
Hearing the words of Danny, the long-haired boy, the girl looked at the back in front of her,
Genius on the left, madman on the right.
Who the hell is he?
Then
Many students noticed Professor Jeff's expression, he seemed so calm and calm, as if he didn't have any feelings for the genius next to him, as if all this was taken for granted.
Don't... Do the two know each other?
Otherwise, why would Professor Jeff be expressionless?
"Alas!"
"I feel... This back is very familiar, is it a delusion on my part?" said a black classmate: "I seem to have seen this back not long ago, really... I've actually seen it, but I just can't remember where I've seen it. ”
"Then you're talking in vain. The white man on the side was speechless at the same time.
"It's not!"
"I really saw it, I swear to God. The black classmate said seriously, "And just in the near future." ”
In fact
This is not the case with the white classmates on the side, but unfortunately... I just can't remember who he is, if he's a celebrity, I must know who he is, but alas... He's not a celebrity.
Xu Mang is still struggling to calculate, but he is about to enter the final stage.
A minute later,
Xu Mang obtained a very long equation and a complex conjugate equation, but the self-consistent equation at this time is an equation that satisfies the single-electron wave function, although it is a little simpler than the wave equation, but after all, it is a nonlinear system of differential integral equations.
It couldn't be easier!
Xu Mang began to approximate step by step, using an appropriate central field instead of the previous long equation, after finding the single-electron wave function, the obtained wave function was brought into the central field, its value was calculated, compared with the original value, and then the central force field was fine-tuned.
This process... Slightly time-consuming.
Because it must be within a required accuracy range, the test center field must be consistent with the calculated center field.
While Xu Mang was trying to reach unanimity,
The students gradually woke up from the shock, and as the answer gradually approached, the whole process became clearer and clearer, and it was then that the students really realized the horror of Xu Mang.
“...”
“...”
“...”
How can this be calculated?
How exactly is this done?
Five minutes later,
Xu Mang has finished all the calculations, and in fine-tuning the central force field, he has proved its physical significance.
"Ahem!"
"Attention... This process does not take into account the exchange of electrons against the symmetric requirements. Xu Mang came to the first blackboard, pointed to the product of the wave function of each electron, and said solemnly: "If we take into account the antisymmetric requirement of the exchange of electrons, then the quantum state of each electron should be represented here. ”
"Of course..."
"Due to time constraints, I will no longer prove the antisymmetry of the exchange of electrons in the wave function of a multi-electron system. Xu Mang smiled and said, "You will come into contact with it in the future." ”
This...
This...
Who the hell is this guy?
"Professor Xu!"
"Thank you for the live teaching. Professor Jeff smiled at Xu Mang and said, "I didn't expect to be able to capture you alive here." ”
“???”
“???”
“???”
What the?
Professor Xu?
He... He's a professor?
I don't feel like I want to think about it at all, he's more like a student, right?
At this point,
Xu Mang was also frightened, this was actually recognized, what was said to be good, why did it suddenly not work?
"I remember!" A girl stood up excitedly, pointed at Xu Mang and shouted: "Professor Xu Mang, an authority in the field of superconductivity and black holes, one of the judges of the Future Science Prize, and an outstanding leader in the frontiers of physics." ”
Words fall,
There was an uproar, and everyone knew who the young man was.
No wonder he is so familiar, the Internet was full of his reports before!
thereinto
The most excited thing is that the girl named Casey, she actually got the guidance of Professor Xu, at this time she glanced at the equation in her notebook, and was even more determined to go down this road of no return in physics.
Having said that,
This Professor Xu is too narcissistic, right?
And also married...
At this point,
Most people are still silent in surprise, after all, it is not easy to see Xu Mang, the most important reason is that he is a foreigner, unless he goes to Huaguo on the west coast of the Pacific Ocean to meet him, there are no special circumstances, basically not to see him.
Bang Bang Bang!
There was applause and a look of respect.
soon
The noisy classroom returned to calm.
"Professor Xu. ”
"There's still an hour. Professor Jeff smiled, "Can you lighten your view of the future and your latest trends so far?"
view of the future,
What's new...
Xu Mang thought for a while, and said with a serious face: "Learn physics well and go to the universe!"
"It's over?"
"It's over!"
Suddenly,
The students present looked depressed, this is too perfunctory, right?
"Ahem!"
"Professor Xu... Why, let's talk about your latest movements, right?" Professor Jeff asked, "You bought MIT's laser interferometer for 100 million yuan, are you planning to enter the field of gravitational wave detection?"
"That's right!"
"At present, the laboratory has been built, and I have received letters of appeal from all over the world, hoping to participate in this detection project, and now the personnel have basically been decided, and it is estimated that the gravitational wave detection will be officially launched in April. Xu Mang said.
"And do you have the confidence to be the first to detect it?"
The question...
It's a bit of a lure into the pit.
But Xu Mang doesn't care, there are only two devices in the world, which were bought by his father-in-law, what do others have to compete with? Why can't you be scolded?
"Of course!"
"I'm going for the Nobel Prize in Physics. Xu Mang said with a smile.
Although it is a bit arrogant, many people here want to believe that Xu Mang can win the Nobel Prize in Physics, and some of Professor Xu's research findings are fully qualified to win international awards, but so far he has not won any awards, which is indeed regrettable.
How to say it...
Many international awards owe Professor Xu a trophy.
"Actually, I'm like a human..."
Then
A song of "Poultry, You Are Too Beautiful" sounded, Xu Mang glanced at Xiao Man's call again, and silently hung her up.
"What..."
"I'm sorry, I'm leaving. Xu Mang said embarrassedly and politely: "Come back next time you have time, professor... See you soon!"
"Hmm!"
Of course, Xu Mang walked to the door, suddenly stopped, turned back to the students present and said, "Students, goodbye!"
moment
Xu Mang's figure disappeared from view.
The students present knew that the next time they met would probably be at the Nobel Prize in Physics ceremony.
...
"Bastard!"
"Where the hell are you?"
At this point,
Yang Xiaoman finally got through Xu Mang's phone, and the anger accumulated in his heart roared at him: "I called you so many times, and you didn't answer any of them... Are you going to die? Tired of living, aren't you? I don't know who you're listening to at home?"
Xu Mangxin smiled awkwardly: "What... At that time, the situation was quite special, and it was full of people... I can only hang you up, this is not... Just escaped. ”
"Cut!"
"Anyway, you're dead!" Yang Xiaoman snorted coldly and said angrily: "Now come to the general office of the mathematics major, and ask if you don't know the way." ”
"Oh..."
After you hang up,
Yang Xiaoman looked up at his cousin and said with a smile: "He's here." ”
Because they spoke Chinese to each other, many of the professors present did not understand, but Xiaoman's cousin heard it clearly, and the word 'frightened' was written all over her face at this time.
This...
Is this still the little man I know?
"Professor Mu?"
"What's the situation now?" a professor hurriedly asked, "Professor Xu Mang, is he here?"
Cousin Xiaoman looked at the crowd present, nodded helplessly and said, "He... He'll be there soon, don't rush. ”
......
