Chapter 695

He...

he wrote?

The news was like a bomb, which made everyone at the scene confused. It was eight textbooks. As a result, Xu mang said that all the eight new textbooks were compiled by him alone. The workload was huge, and it took at least several years to write them.

"Professor Xu mang?"

"Are you... Are you sure you wrote it yourself?" A professor asked curiously, "but it's not right. I heard that the completion time of this set of basic physics textbooks is very short. How can one complete it in a short time?"

"I don't know."

"After receiving the notice, I'll write by myself for a few days." Xu mang tilted his head, recalled the past scene, calmly said: "then suddenly one day to the new textbook to compile, probably so... In fact, it's no big deal."

"..."

"..."

"..."

"..."

although it was so understatement, many people at the scene felt that Xu Mang's bland tone was filled with a trace of pride, which many people questioned. We have to admit that Xu mang has played a very strong role in the field of scientific research, and has almost become the spokesman of Chinese scientific research abroad, but his teaching ability is... True We can't agree.

On the way to the designated multimedia classroom, Hu Feng was questioned by many professors. He kept asking whether the author of the textbook was Xu mang. There was no way... Since Xu mang had been made public, Hu Feng could only tell them everything.

"Yes

"It took Professor Xu mang only a few days to complete all the teaching materials." Hu Feng seriously said: "although I don't know why the speed is so fast, but after the examination of the academicians of the Institute of physics, they all agree that it is perfect!"

In a flash,

the crowd was silent, and many people could not accept the news.

Just a few days?

Perfect?

Why does it sound like listening to a book?

Many people take a sneak look at Xu Mang and see that his whole state is a little decadent and his eyes are a little lax. It is impossible to imagine that such a person could complete a set of basic physics textbooks in a few days, and... He has won a good comment from the academicians of the physics research Institute.

BR,

is simply a miracle of

.

Soon,

arrived in the classroom, a huge multi-media classroom. The students were freshmen from all over the world. They were frightened and expected to be able to sit here and hear the legendary Professor Xu mang.

"Lying trough!"

"Professor Xu is really young." A girl saw Xu mang standing on the podium, and for a moment fell into a mania. She thought about her professors, and then looked at Professor Xu in front of her. Why are other professors so handsome? And the professors who teach themselves are all... Forget it, they are all tears.

"..."

"I heard that Professor Xu mang is only 20 years old?" The girl sitting on the edge said curiously: "it's a pity... I heard that Professor Xu has a fiancee. I really don't understand how such an excellent man can enter the grave of marriage so quickly."

"I wonder, too!"

"You say that there are people in the world who are worthy of Professor Xu. What are their origins?" The girl with glasses frowned, with a trace of discrimination against her: "I think Professor Xu has been threatened!"

At this time,

at this time,

there are still 15 minutes before class, and many people take out their mobile phones one after another, facing Xu Mang, which is a strong shot, and even live broadcast. In short, it records this magical encounter.

Photos,

a video,

suddenly began to spread wildly on the Internet, and even the news that Xu mang was going to resign at Fuda and go to Qingda was revealed. However, this kind of news was soon clarified by the official microblogs of the two schools. There was no way... As for Xu Mang, the speed of public relations was so fast.

However, as a young man, Xu mang can't help but take out his mobile phone and take a self portrait of himself in the background of this group of students.

As time went by,

there were still a few minutes before class,

at this time,

the students noticed that Xu mang didn't seem to bring his textbook with him?

Ding Lingling ~

the bell rings,

all the students gathered up their relaxed mood and changed their serious and rigorous attitude to deal with the next experience. Maybe it will be an unforgettable journey.

"Cough!"

"Class is over

"I'm going to randomly extract something from quantum mechanics." Xu opened a software, casually click, there is no way... The above requires the scene to take random content teaching, in order to test when the professor did not prepare the premise, how the students absorb."Er..."

"time dependent approximation methods and transitions."

Xu mang took a look at the topic, got up and took a look at the projection behind him. He said calmly, "please turn to page 221 of basic physics quantum mechanics, and the class will begin formally below!"

“？？？”

“？？？”

“？？？”

Autumn bean sack!

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 teaching material group. They were all shocked by Xu Mang's memory. They were sure that this was not the content of the play that had been performed before.

"This..."

"does he know all the content?" Hu Feng widened his eyes, looked at Xu Mang in horror, and muttered: "my God, he knows all the contents of thousands of words?"

However,

Xu mang did not give anyone time to continue thinking. Standing on the stage, Xu said quietly: "first, we will talk about the selection rules of atomic states that absorb or emit a photon under the action of electric dipole."

"This involves three aspects: first, the description of the selection rule of electric dipole transition for atomic states that absorb or emit a photon; second, the explanation of orbital angular momentum, spin, helicity and parity of photons; and the third 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 chalk, while talking about the content, while analyzing the content. He did not read a word in the textbook, but it was completely consistent with the content.

"Attention

"When we calculate the electron volt width of 2p state, we must follow the uncertainty relationship..."

in front of the blackboard, Xu mang talked more and more smoothly. In a flash, he talked about the content of the fifth part, about the distribution of energy and momentum of particles in one-dimensional infinite potential well when the wall is suddenly removed.

As for this content,

there is no corresponding explanation in the textbook, and Xu mang only gives a topic.

"When the wall is suddenly separated and infinitely distant, that is, the wall is completely disassembled in an instant. The wave function of particles in this instant is too late to react, so it will keep its original shape. However, the Hamiltonian after the wall is disassembled is different from that before demolition."

"The original form of the 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,

in the last few rows of the multimedia Professor,

listen to Xu Mang's class content quietly, watch him explain the particle problem in one-dimensional infinite potential well on the stage with his own memory, and then read his own textbook, the content is exactly the same, even not a word is wrong.

Of course,

in the content of completely compatible content is only limited to the topic itself, and to analyze the content of the topic, Xu mang is still in the current class environment. After all, the particle problem in one-dimensional infinite potential well is not the content of Freshmen's contact, but he is easy to understand and absorb this knowledge.

"Alas..."

"if you don't bring a textbook, you can speak so perfectly. If you bring a book, at least half of these 30 students will be future Nobel Prize winners in physics." A professor said with a wry smile, "I'm not joking, really... Not at all!"

Several people around did not speak and quietly felt the experience brought about by the new teaching material. Perhaps it was because Xu Mang's teaching that this experience had risen to a higher level. However, there was a saying that this new set of teaching materials was very good, no... it was perfect!

As time passed by, until the moment the bell rang, the freshmen could not believe that the class time was so short that it seemed that the class had just been over for five minutes.

Oh, my God!

Are you going to part with Professor Xu?

"Eh?"

"Class over?" Xu mang half of the talk, looked at the blackboard to write half of the title, helplessly said: "class is over... Then class is over!"

"Professor Xu, ten more minutes!"

"Professor Xu, finish talking about this topic."

"We have a class!"

In the face of the tide of requests, Xu mang did not give them face, seriously said: "I'm sorry... I'm not a drag class teacher, class is over!"

In a wail,

class is over.

However, since it is the end of the class, more than 30 students become more crazy and rush to Xu Mang in an instant. In order to meet the students' request for cooperation, Xu mang decides to take a photo to commemorate the first battle of the new textbook.

"Chief Hu!"

"Please take a picture for us!" Xu Mangchong's stupefied Hu Feng shouts.Hu Feng:???

I...

I'm a leader at XX level, and I'm reduced to taking photos.

However, in the face of Xu Mang, Hu Feng has no way. This is the niece of the leader. He is not a simple second generation. From another perspective, he is the first generation of science.

A precious picture was taken.

watching the students leave, Xu mang came to the last few rows of the classroom and asked with a smile, "everyone? How about it? "

"..."

"..."

"..."

"..."

although we want to say perfect, we can look at Xu Mang's cheap smile, and instantly five flavors are mixed.

Finally,

still abides by the facts and admits that this set of teaching materials is perfect.

At the same time,

on the Internet,

a photo suddenly appeared, which triggered a wave of craze.
