I Don’t Want to Win Lying Down

he...

He wrote it?

This news was like a bomb, which confused everyone present. There were eight textbooks, but Xu Mang said that he wrote all the eight new textbooks by himself. It takes 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 of this set of basic physics textbooks...is quite short, how to do it to be completed by one person in a short period of time?

I don't know either.

After receiving the notice, I wrote it alone for a few days. Xu Mang tilted his head, recalling the past scene, and said calmly: Then suddenly one day, he finished compiling the new textbook, probably like this. ..it's not really a big deal.

...

...

...

Although he said it so lightly, many people present felt that there was a hint of pride in Xu Mang's flat tone, and this kind of pride made many people question it. They had to admit that Xu Mang had played a very strong role in the field of scientific research. , has almost become the spokesperson of Huaguo's scientific research to the outside world, but his teaching ability... I really don't agree.

On the way to the designated multimedia classroom, Hu Feng was questioned by all the professors, who kept asking if the author of the textbook was Xu Mang. Everything was told to them.

right!

Professor Xu Mang completed all the contents of the textbook in just a few days. Hu Feng said seriously: Although I don't know why the speed is so fast, after review by the academicians of the Institute of Physics, they agreed that it was very Perfect!

in an instant,

The crowd fell 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 secretly glanced at Xu Mang,

Seeing that he is a bit decadent and his eyes are a little slack, it is unimaginable that such a person can complete a set of basic physics textbooks in just a few days, and... won the academician of the Institute of Physics their praise.

have to say,

Xu Mang was synonymous with miracles.

soon,

Arriving at the teaching classroom, a huge multimedia classroom, the students are freshmen from all corners of the country. For being able to sit here and hear the legendary Professor Xu Mang give a lecture, there is a tinge of anticipation in their trepidation.

Fuck!

Professor Xu...so young! A girl saw Xu Mang standing on the podium, and fell into a nympho state for a while, thinking about her professors, and then looking at Professor Xu in front of her, why? Why is someone else's professor so handsome? And the professors who taught me were all... Forget it, they were all tears.

...

I heard...Professor Xu Mang is only in his twenties, right? The girl sitting on the side said curiously: It's a pity... I heard that Professor Xu has a fiancee. I really don't understand why he is so outstanding. How could such a man enter the grave of marriage so quickly?

I wonder too!

You say that there is someone in the world who is worthy of Professor Xu, what is the background of the other party? The girl with glasses frowned, with a trace of discrimination on her face: I think Professor Xu has been threatened!

at this time,

There are still fifteen minutes before class starts, and during these long fifteen minutes, many people took out their mobile phones and kept taking pictures of Xu Mang, and there were even live broadcasts. encounter.

a picture,

a piece of video,

Suddenly it started to go viral on the Internet, and there was even news that Xu Mang was going to resign from Fuda and go to Tsinghua University, but this news was soon clarified by the official Weibo of both schools. There was no way... When it came to Xu Mang, the speed of public relations was so fast.

But as a young man, Xu Mang couldn't help but took out his phone and took a selfie of himself, of course, with this group of students in the background.

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 a textbook... Could it be that Professor Xu is relying entirely on memory?

jingle bell~

the bell rings,

All the students at the scene put away their 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, clicked it casually, there was no way... The above required random content to be taught on the spot, so as to test the premise that the professor was not prepared, the students their receptivity.

Well...

Time-dependent approximation methods and transitions.

Xu Mang glanced at the topic he was drawing, then got up and glanced at the content of the projection behind him, and said calmly, Please turn to page 221 of Fundamental Physics——Quantum Mechanics, and the class will officially start now!

???

???

???

Autumn Bean Sacks!

this...

Does this directly report the number of pages?

Everyone in the multimedia classroom was stunned for a moment, including the professors sitting in the back row, and Hu Feng, the leader of the silent textbook group, who were taken aback by Xu Mang's memory. They were sure that this was not a premise. past acting content.

this...

Does he know all the content? Hu Feng stared wide-eyed, looked at Xu Mang in horror, and muttered, My God... the content of tens of millions of words, he actually knows all the content?

However,

Xu Mang didn't give anyone time to continue thinking. He stood on the stage and said silently, Let's talk about the first content first, about the selection rules of the atomic state that absorbs or emits a photon when the electric dipole interacts.

This involves three aspects, the first is the description of the selection rule of the electric dipole transition for the atomic state that absorbs or emits a photon, the explanation 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 electric dipole transition selection rule, we can...

Xu Mang stood in front of the blackboard, holding a chalk, while explaining the content, while analyzing the content, he didn't read a single word in the textbook, but it was completely consistent with the content.

Notice!

When we calculate how many electron volts the width of the 2P state is, we must follow the uncertainty relation...

Xu Mang, who was in front of the blackboard, spoke more and more fluently. In a blink of an eye, he talked about the fifth part, the distribution of energy and momentum of particles in a one-dimensional infinite deep potential well when the wall was suddenly removed.

About this content,

There was no corresponding explanation in the textbook, Xu Mang just asked a question.

When the wall is suddenly separated and the distance is infinite, it means that the wall is completely disassembled in an instant, and the wave function of the particle has no time to respond in this instant, so it will maintain the original shape, but the Hamiltonian after the dismantling of the wall has already It's different from before the demolition.

The wave function in the original form is not the eigenstate of the newly removed Hamiltonian, so...the initial condition of the basic wave function is to solve the Schrödinger wave equation for free particles.

at the same time,

The last few rows of multimedia professors,

Listening quietly to the content of Xu Mang's class, watching him explain the problem of particles in a one-dimensional infinite deep potential well on stage with his own memory, and then flipping through the textbook in his hand, the content is exactly the same, even one No words are wrong.

certainly,

The fully compatible content is limited to the topic itself, and Xu Mang is still in the current class environment for analyzing the content of the topic. After all... the problem of particles in a one-dimensional infinite deep potential well is not something freshmen are exposed to, but He speaks plainly and easily absorbs the knowledge.

well...

I can speak so perfectly without textbooks. If I brought books... I estimate that at least half of the thirty or so students are future Nobel Prize winners in physics. A professor smiled wryly: I'm not kidding, really... not at all!

The few people around did not speak, and quietly felt the experience brought by the new textbooks. Perhaps it was because of Xu Mang's teaching that this experience has been raised to a higher level, but there is one thing to say, this new set of textbooks is very good, no. ..is perfect!

Time passed by every minute and every second, until the moment the bell rang, the first-year students present couldn't believe that the class time was so short, as if the get out of class ended after just five minutes.

God!

Are you going to part with Professor Xu?

Huh?

get out of class is over? Xu Mang was in the middle of speaking, glanced at the half-written topic 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 another ten minutes!

Professor Xu, finish this topic!

We're going to class!

Facing the flood of requests, Xu Mang didn't give them any face, and said seriously, I'm sorry...I'm not a teacher who procrastinates, let's dismiss the get out of class!

in a wail,

get out of class has ended.

However, since get out of class was over, the thirty or so students became even more frantic and flocked to Xu Mang's side in an instant. In order to meet the cooperation requests of the majority of students, Xu Mang decided to take a photo together to commemorate the first battle of the new textbook.

Group Leader Hu!

Please take a photo for us! Xu Mang shouted at Hu Feng who was in a daze.

Hu Feng:? ? ?

I...

I'm a leader at the XX level, and I'm actually reduced to taking pictures.

But facing Xu Mang, Hu Feng had no choice. This is the leader's leader's niece-in-law, just kidding... He is not a simple second generation. Thinking from another angle, he is the first generation of Ke.

Click,

A precious photo was taken,

Watching the students leave, Xu Mang came to the last few rows of the classroom and asked with a smile, Everyone? How are you doing?

...

...

...

Although he really wanted to say it was perfect, looking at Xu Mang's mean smile, he had mixed feelings in an instant.

finally,

Still abide by the facts and admit the perfection of this set of textbooks, it is indeed perfect.

at the same time,

on the Internet,

A photo suddenly appeared out of nowhere, triggering a wave of upsurge.
