The day before the start of the university, most of the students had already arrived at the school, and some even arrived a week early, but almost all of these students were nestled in the dormitory, playing games every day, day and night.

"Huh?"

"Have you heard?" a student in a freshman dormitory said to his roommate, "Professor Xu Mangxu is the acting deputy director of our physics department, and I just looked at the course schedule, he teaches a compulsory course, advanced mathematics, and three elective courses are quantum field theory, nonlinear physics, and relativistic mechanics. ”

"it!"

"Then I won't choose any of these three electives. Another student said in horror: "If you want to get credits from Professor Xu, I'm afraid it's even more difficult than climbing to the sky." ”

"Yes!"

"But it just so happens that quantum field theory is qualified for relativistic mechanics, and we can't help but choose... It's embarrassing. The student said bitterly.

It's really embarrassing,

For Professor Xu Mangxu, all the students in the Department of Physics have mixed feelings about him, because of this kind of person... People who have no moral bottom line actually produce the kind of math papers that are as difficult as the sky, causing batches of students to fail.

However, he has incomparable wisdom, and in just half a year, he has obtained an impact factor of more than 250, and he has been on the cover of the journal five times, two of which have been on the cover of the journal.

It's really angry, hateful, and awe-inspiring.

"Do you know about the Internet scolding war a few days ago?" said the former classmate: "Professor Xu is also awesome enough, the whole network is live... Ka Ka Ka slapped those big V public knowledge in the face, and now those people don't dare to speak. ”

"No!"

"As far as those so-called big V are known, they really take themselves seriously, and they don't look at who Professor Xu is. Another student said with a disdainful look on his face.

meanwhile

Xu Mang was planning to fool Xiao Man.

"Hey!"

"What did I say you do?" Yang Xiaoman was lying on the sofa, seeing Xu Mang's anxious face, he asked curiously: "Like a big idiot, hurry up and stop my mother, I will be dizzy when I see you." ”

“...”

"Xiao Man?" Xu Mang walked to Xiao Man's side, hugged her into his arms with a smile, and said gently: "I bought a car..."

"Huh?"

"Did you buy a car?" Yang Xiaoman was stunned for a moment: "Why don't I know?"

Xu Mang opened his mouth, if you knew this, you might have to twist your head off.

What to do?

How do you fool the past?

After thinking about it carefully, Xu Mang decided to take Xiao Man around and let her experience the fun of heavy locomotives.

"Let's go!"

"Pick up the car with me!"

soon

The two came to a big trade motorcycle shop, Yang Xiaoman's face pulled down on the spot, she hated motorcycles the most, it was too dangerous.

"You bought a motorcycle?" Yang Xiaoman said angrily with a black face.

"Hehe!" Xu Mang leaned into Xiao Man's ear and said softly: "Actually, I bought two!"

Yang Xiaoman: (* ̄〈 ̄)

Two more?

You don't know how to write dead characters, do you?

"No way!"

"I want to ride a motorcycle for the rest of my life!" Yang Xiaoman said: "If you dare to pick up the car today, you will sleep with the sofa for the rest of your life!"

Words fall,

Xiao Man left without looking back, but was forcibly dragged by Xu Mang.

"Release!"

"I'm telling you... I will never ride your motorcycle in my life!" Yang Xiaoman shouted at Xu Mang while struggling: "I won't be able to die!"

An hour later,

Yang Xiaoman sat in the back seat of the Ducati big devil, hugged Xu Mang's waist and shuttled through the traffic.

It's so angry!

In the end, I still didn't resist this guy's sweet words.

A sentence I love you...

was taken down by him.

It's finally time for the start of the school year at Fufu University.

Xu Mang changed to a Ducati 1299 and drove Xiao Man to school, speaking of these two heavy locomotives, he was criticized by Yang's father and Yang's mother last night, but fortunately, Xiao Man helped a lot and persuaded her parents.

“？？？”

“？？？”

“？？？”

I'll go!

Isn't this Professor Xu Mangxu?

it!

So handsome!

Xu Mang sent Xiaoman downstairs to her dormitory, and the moment she took off her helmet, all the students nearby were stunned, dressed in a handsome motorcycle uniform and a super cool carbon fiber helmet, I'm afraid this is the most fashionable professor in history, right?

The love affair between Xu Mang and Yang Xiaoman has long been known, although there are many rumors to slander, but the overall situation is quite good, and many people have been conquered by the pure love between Xu Mang and Yang Xiaoman.

But...

Now there is something impure.

"I'm leaving. ”

"Hmm..."Yang Xiaoman nodded: "Pay attention to safety!"

Leaving Xiaoman's campus,

Xu Mang drove his motorcycle to the physics department building, as the deputy director of the physics department, Xu Mang naturally parked the car downstairs, not for anything else... It's just to let more students see their newly bought locomotives, which is so vulgar.

"Hello Professor Xu!"

"Professor Xu, morning!"

"Professor Xu..."

On the way to the office, Xu Mang met many students, who were still as enthusiastic as before, and did not ignore each other because Xu Mang gave them a high number of failures.

At this point,

Director Fang was holding his briefcase, just walked out of the cafeteria, and when he came to the physics department building, he couldn't help frowning when he saw a cool motorcycle supercar.

What bastard would dare to be so presumptuous?

Ignoring school rules?

"Alas!"

"Whose car does it belong to?" Director Fang asked with a black line on his face, catching a classmate.

"Professor Xu's. ”

Director Fang: ???

This...

Also

Whoever dares to be so bold in school will be bold.

When he came to Xu Mang's office, Director Fang pushed the door directly and entered, and saw that he was holding Erlang's legs and holding a mobile phone in his hand, obviously playing a game, good guy... There's no such thing as a deputy director at all!

"Xu Mang!"

"Why did you park your motorcycle underneath?" Director Fang said angrily, "As the deputy director of the physics department, how can you take the lead in playing a bad role?"

"It's convenient!"

"Oops... Director Fang has nothing to do. Xu Mang smiled and said: "I see that many students park their bicycles downstairs, why can't my locomotive? It's all two-wheeled, why can't it?"

“...”

"I said you kid raised the bar with me, didn't you?" Director Fang said helplessly: "Forget it... You can do whatever you like, but don't be too fast in school. ”

"Hmm!"

Words fall,

Xu Mang hurriedly said, "Director Fang... The list hasn't been decided yet, has it?"

"Not yet. ”

"There is a girl named Hu Jie in her sophomore year, which is very good... She was the only one who passed the theoretical physics exam. Xu Mang said: "Give her a chance to exercise." ”

"Hu Jie?"

"I see. Director Fang nodded and glanced at Xu Mang: "You seem to be very relaxed?"

Xu Mang was stunned for a moment, glanced at his empty desktop, and said with an embarrassed face: "I'm going to be busy soon... It's true... I... I have to prepare for class, and it seems that tomorrow afternoon there will be my advanced math class, the third year of theoretical physics. ”

"Then prepare for class. ”

After that,

Director Fang left the office.

Looking at the back of Director Fang's departure, Xu Mang showed a disdainful smile, this still needs to prepare for class?

At this point,

Xu Mang took out the parameters of the laser interference equipment from the drawer, and he had to write a detailed plan for the next detection of gravitational waves, otherwise it would be difficult to succeed if someone had the equipment but did not have a detailed plan.

However, when Xu Mang picked up the pen, he found that he could not find an entry point at all, and in the end Xu Mang could only start with the general theory of relativity, in which the linearized weak field equation has a wave solution, a transverse wave propagating at the speed of light, and this transverse wave is generated by the time variable of the mass quadrupole moment.

In this way, according to the prediction of general relativity, the main task of his laboratory is to observe black holes, collect the waveforms of black holes, and find out the data that conform to the general theory of relativity on the spiral and merger of black holes and the formation of a single black hole.

There should also be a dense binary system...

But

How do you do this?

Academically,

Xu Mang belongs to the kind of person who is good at theory, but he doesn't know anything about practical operation.

In desperation, Xu Mang handed over this task to Brother Chuan Xiao, as a professional astrophysics researcher, there should be no problem with the arrangement of the plan.

As a result by the afternoon,

Xu Mang received an email from Brother Chuan Xiao, opened it and saw a very detailed plan report.

"This ability..."

"I need a salary increase!" Xu Mang was very satisfied with Brother Chuan Xiao's efficiency.

In Brother Chuanxiao's plan, every step is very detailed, even down to the specific steps that everyone needs to do.

First of all

Finding a compact binary system, then analyzing the possible probabilities, then detecting the frequency bands of this dense binary system, and finally receiving the signal of this dense binary system and computational relativity calculations and fitting.

At night

Xu Mang arrived at his new residence, a thirty-square-meter apartment, not to mention that although the area is not large, there should be everything in it, such as refrigerators, washing machines, air conditioners, etc.

silently took a photo and sent it directly to Yang Xiaoman, stimulating her nerves, and sure enough... Ten seconds later, the phone rang, and the caller was none other than Xiao Man at the violent airport.

Then he was scolded,

Xu Mang spent another half an hour comforting her.

At this moment, Xiao Man is very puzzled, why do boys like to spend a minute to provoke their girlfriends, and then spend half an hour to make her happy, is this a brain problem?

And the answer given by Xu Mang... Because idle.

Following

It's still the same as yesterday, coming to the office to sit in a daze, for the current Xu Mang, he needs to stay up until the afternoon, and he won't be bored in the afternoon.

Time came to the afternoon,

Xu Mang looked at his mobile phone, there were still five minutes to go to class, and it was almost time to go.

The physics department building has long been familiar, Xu Mang can find the classroom with his eyes closed, and the classroom of the third year of theoretical physics is on the second floor.

"it!"

"What about people?" Xu Mang came to the classroom, horrified to find that there was no one.

What's the situation?

Where did the students go?

Play truant?

There's no way the whole class is running away, right?

"It's over, it's over..."

"It looks like a different classroom. Xu Mang panicked and his back was cold, don't swear casually, the consequences will be unimaginable!

In twenty minutes,

Xu Mang found the classroom where he needed to take classes, looking at the helpless demeanor of the students present, Xu Mang smiled awkwardly, and said indifferently: "I'm sorry... Lost. ”

“...”

“...”

“...”

For this reason,

It's ridiculous!

Two hours later, Xu Mang was about to go back to the apartment after class, and just opened the door of the apartment, he received a call from his second grandfather.

"Xu Mang..."

"You can come to my office and kill yourself. ”

......
