Chapter 695: The process is perfect

he...
He wrote it?
This news is like a bomb, which confuses everyone present. Those are eight textbooks. As a result, Xu Mang said that all the eight new textbooks were written by himself. The workload is huge, and at least it needs to be written. It took several years.
"Professor Xu Mang?"
"You... are you sure you wrote it yourself?" A certain professor asked curiously: "But it's not right. I heard that the completion time for this set of basic physics textbooks... is quite short. How to do it Can it be done by one person in a short time?"
"I do not know either."
"I received the notice, and then I wrote it alone for a few days." Xu Mang tilted his head, recalling the past scene, and said calmly: "Then suddenly the new textbook was compiled one day, and that was it. .. Actually it's not a big deal."
"..."
"..."
"..."
Although it was such an understatement, many people in the audience felt that Xu Mang’s plain tone had a hint of pride, and this pride made many people questioned. They had to admit that Xu Mang played a strong role in the field of scientific research. He has almost become the spokesperson of Huaguo's scientific research, but his teaching ability... really disagrees.
On the way to the designated multimedia teaching classroom, Hu Feng was questioned by many professors. They kept asking whether the author of the textbook was Xu Mang or not. There was no way... Since Xu Mang has been published, Hu Feng can only Everything was told to them.
"Correct!"
"Professor Xu Mang completed all the content of the textbook in just a few days." Hu Feng said earnestly: "Although I don't know why the speed is so fast, after reviewing by the academicians of the Institute of Physics, they agreed that it is very perfect!"
In an instant,
The crowd was silent, and many people could not accept the news.
Just a few days?
very perfect?
Why does it sound like listening to a book?
Many people took a peek at Xu Mang and saw that his whole state was a little bit decadent, and his eyes were a little loose. It was impossible to imagine that such a person could complete a set of basic physics teaching materials in just a few days. ...Won the praise of the academicians of the Institute of Physics.
have to say,
Xu Mang is simply synonymous with miracles.
soon,
In the teaching classroom, a huge multimedia classroom, the students are freshmen from all corners of the world. There is a trace of anticipation for being able to sit here and hear the legendary Professor Xu Mang lecture.
"Fuck!"
"Professor Xu...really so young!" Seeing Xu Mang standing on the podium, a girl fell into an idiot for a while. Think about her professors, and then look at Professor Xu in front of her. Why How handsome are other professors? And the professors who taught themselves were all... forget it, they were all tears.
"..."
"I heard...Professor Xu Mang is only in his twenties?" The girl sitting next to him said curiously: "It's a pity... I heard that Professor Xu has a fiancée. I really can't figure it out. Man, why did he enter the tomb of marriage so quickly."
"I wonder too!"
"You say there are people in the world who can be worthy of Professor Xu. What is the background of the other party?" The girl with glasses frowned, with a trace of discrimination against her on her face: "I think Professor Xu is threatened! "
at this time,
There are still fifteen minutes before class. In this long fifteen minutes, many people took out their mobile phones and shot Xu Mang vigorously. There were even live broadcasts. In short, they recorded this magical time. Encounter.
Pictures,
A piece of video,
Suddenly it began to go viral on the Internet, and there was even news that Xu Mang was going to resign at Fuda and go to the National Tsing Hua University. However, this news was clarified soon. The official Weibo of the two schools clarified that there was no way... involved To Xu Mang, the speed of public relations is so fast.
However, as a young man, Xu Mang couldn't help taking out his mobile phone and taking a selfie of himself. Of course, the background was this group of students.
As time goes by,
There are still a few minutes before class,
at this time,
The students noticed that Xu Mang didn't seem to bring his textbook... Could it be that Professor Xu relied on memory?
Jingle bell~
The bell rang,
All the students present picked up their relaxed and playful emotions, and put on a serious and rigorous attitude to deal with the next experience. Perhaps this will be an unforgettable journey.
"Ahem!"
"Class begins!"
"I am now randomly selecting a certain content of quantum mechanics." Xu Mang opened a software and clicked it casually. There was no way... The above asked the students to take random content to teach on the spot, in order to test the premise that the professor was not prepared. What is their receiving ability.
"Uh..."
"Time-dependent approximation and transition."
Xu Mang glanced at the subject he had drawn, got up and glanced at the content of the projection behind him, and said calmly: "Please turn to page 221 of Basic Physics-Quantum Mechanics, and the class will officially start next!"
"???"
"???"
"???"
Autumn bean sacks!
This...
This will directly report the number of pages?
Everyone in the multimedia classroom was stunned, including the professors sitting in the back row and Hu Feng, the leader of the silent teaching material group. They were all taken aback by Xu Mang’s memory. They were sure that this was not a prerequisite. Past acting content.
"This..."
"Does he know all the content?" Hu Feng widened his eyes, looked at Xu Mang in horror, and muttered, "God...he knows all the content in ten thousand words?"
however,
Xu Mang did not give anyone time to continue thinking, standing on the stage and silently said: "First, let me talk about the first content, about the choice of the atomic state that absorbs or emits a photon when the electric dipole acts."
"This involves three aspects. The first is the description of the choice rule of electric dipole transition for the atomic state that absorbs or emits a photon, and the interpretation of the orbital angular momentum, spin, helicity, and parity of the two photons. Its three Bohr model."
"The first two are very simple. According to the selection rule of electric dipole transition, we can..."
Xu Mang stood in front of the blackboard, holding a chalk, while telling the content while analyzing the content. He did not read a word of the textbook during the whole process, but it completely matched the content.
"note!"
"When we calculate the width of the 2P state in electron volts, we must follow the uncertainty relationship..."
Xu Mang in front of the blackboard, the more he speaks, the more fluent he speaks. In a blink of an eye, he comes to the fifth part, the issue of the distribution of energy and momentum of particles in a one-dimensional infinite potential well when the wall is suddenly removed.
Regarding this content,
There is no corresponding explanation in the textbook, and Xu Mang just asked a topic.
"When the wall is suddenly separated and the distance is infinite, the wall is completely dismantled in an instant. The wave function of the particle is too late to react at this moment, so it will maintain its original form, but the Hamiltonian after dismantling the wall is already Different from before demolishing."
"This original wave function is not the eigenstate of the newly dismantled Hamiltonian, so... the initial condition of the basic wave function is to solve the Schrodinger wave equation of free particles."
at the same time,
The last few rows of multimedia professors,
Listening quietly to Xu Mang’s class, watching him use his memory to explain the particle problem in the one-dimensional infinite potential well on stage, and then read the textbooks in his hand, the content is exactly the same, even one. No words are wrong.
of course,
The content that is completely compatible is limited to the topic itself, and when analyzing the content of the topic, Xu Mang is still the environment of the current class. After all... the particle problem in the one-dimensional infinite potential well is not the content of the freshman, but He speaks in an easy-to-understand manner and can easily absorb this knowledge.
"Ugh..."
"You can speak so perfectly without a textbook. If you bring a book... I estimate that at least half of these thirty students will be future Nobel Prize winners." A professor smiled bitterly: "I'm not kidding, really...not at all!"
Several people around did not speak, and quietly felt the experience brought by the new textbook. Perhaps because of Xu Mang’s teaching, this experience has risen to a higher level, but there is one thing to say that this new set of textbooks is very good, no. .. is perfect!
Time disappeared every minute, until the moment the bell rang, the freshmen present couldn't believe that the class time was so short, as if it had only been five minutes before the get out of class ended.
God!
Are you going to part with Professor Xu?
"what?"
"get out of class is over?" Xu Mang was halfway through, and he glanced at the half-written title on the blackboard, and said helplessly: "get out of class is over...then get out of class is over!"
"Professor Xu, let's talk for ten minutes!"
"Professor Xu, let's finish this topic!"
"We are going to class!"
Faced with the flood of requests, Xu Mang didn't give them face, and said seriously: "I'm sorry...I'm not a teacher who dragged the class, let's end the get out of class!"
In a wailing,
get out of class has ended.
However, since get out of class was over, the thirty or so students became even more crazy and flocked to Xu Mang's side instantly. In order to satisfy the students' requests for cooperation, Xu Mang decided to take a photo together to commemorate the first battle of the new textbook.
"Head Hu!"
"Take a picture for us, please!" Xu Mang shouted out of Hu Feng in a daze.
Hu Feng:? ? ?
I...
I am... XX-level leader, turned into a photographer.
But in the face of Xu Mang, Hu Feng has no choice. This is the niece of the leader of the leader, kidding... He is not a simple second generation. From another perspective, he is the first generation of science.
Click,
A precious photo was taken,
Seeing the students leave, Xu Mang came to the last few rows of the classroom and asked with a smile, "Everyone? How is it?"
"..."
"..."
"..."
Although I want to say perfect, UU reading www. uukanshu. com can look at Xu Mang's mean smile, instantly mixed.
finally,
I still abide by the facts and acknowledge the perfection of this set of teaching materials. It is indeed perfect.
at the same time,
On the Internet,
A photo turned out suddenly, triggering a wave of craze.
