Five

Xu Mang hurried to the hotel, originally with his current clothes, he couldn't eat inside, after all, he was too ungentlemanly... However, whoever asked him to marry a violent airport named Yang Xiaoman, even if he was wearing a pair of big pants, he had to let him in.

discovery target,

Xu Mang found Dean, Bill, and Matlie in the crowd, all three of whom he had met, but he didn't know the others.

"I'm sorry..."

"I just came out of the lab. Xu Mang greeted a few people with a smile: "I've made you wait for a long time." ”

"We've just arrived. ”

"Professor Xu would like to introduce to you, this is Henry from the Department of Mathematics, and this is Joseph from the Department of Mathematics, both of whom are professors of mathematics. Dean smiled and said, "They are the ones who invited the banquet today." ”

"Oh..."

"It turned out to be two mathematicians. Xu Mang nodded and said with a smile: "Math is good." ”

“...”

“...”

How it feels,

Professor Xu is a little disgusted with mathematics?

Henry and Joseph were not the only ones who felt this way, but also the three professors in the physics department.

"Professor Xu?"

"Actually, you are quite famous in our industry, and we all know that many of your papers use pure mathematics to reach conclusions. Henry said seriously, "How did you manage to be a physics professor and yet have such a high level of mathematics?"

Belch...

That's a hard question to answer.

It is easy to cause disgust.

"What..."

"I'm not that passionate about math, I don't have the same real emotions as physics, I don't hate it, but I definitely don't like it. Xu Mang said seriously: "You ask me how to have a level, maybe... It's an innate talent. ”

Words fall,

Several people present felt slightly uncomfortable, but this was not wrong, and it was in line with their assumptions about Xu Mang.

"Oops..."

"Let's stop talking about that, let's start serving the food quickly. Xu Mang hurriedly urged: "I came to eat, but I didn't come to chat..."

soon

At Xu Mang's urging, the dishes began to be served, but Xu Mang fell into confusion, he looked at the fried cod, roast beef, and Yorkshire pudding on his plate, and then was completely dumbfounded... What the hell is this?

OMG!

Can you eat this special thing?

ultimately

Xu Mang still endured the discomfort and silently ate the so-called delicacies on the plate, this one called Yorkshire Pudding is not a pudding, similar to a kind of soft bread, with a hollow and soft middle, and crispy on the outside, usually eaten with roast beef.

Roast beef with Yorkshire pudding is the national dish of the United Kingdom and is an important part of the Brit's Sunday dinner.

Returning the national cuisine...

Xu Mang showed a hint of helplessness, at this time he missed Xiao Man's dark cuisine very much, at least... It looks like it's very appetizing.

In fact

Behind the food of every country is a precipitation of its culture and history, and the same is true of the Kingdom of Britain.

In the early years, British food was the most proud of Europe, but... The promotion of Lord Cromwell, the canning of the Industrial Revolution, and the Second World War gradually brought British food to its present state.

Xu Mang ate quickly, and in a blink of an eye, he finished eating all the things on the plate, and he was eating pie at this time.

"Professor Xu?"

"Huh?"

"I'd like to ask you to help me solve a problem. Henry saw the opportunity and hurriedly said: "And this is an astrophysical question, as an authoritative figure in this area, I don't know if you want to." ”

Xu Mang was stunned for a moment, looked at Henry curiously, and asked, "Show me." ”

Words fall,

Henry handed Xu Mang a note with a seemingly brief equation written on it.

This...

There's something complicated about this!

Xu Mang was eating apple pie while looking at the equation on this note, if he let himself complete it, it would take at least about three hours, of course... This time is not to turn on the cheat mode, only to solve it by your own ability.

"This..."Xu Mang glanced at it, and couldn't help frowning and said, "There is a little..."

Halfway through the conversation,

It made several people present nervous.

"It's very simple!" Xu Mang raised his head and said with a smile: "This should be given to you by someone else, right? ”

Henry nodded and said seriously, "You're right. ”

"Professor Xu?"

"This..."

"Since you think it's that simple, can you solve it?" Henry asked, "We've all heard, you helped Professor Matlie solve a long-term split solution, and it only took about fifteen minutes, so... That's not a problem, right?"

"Yes. ”

"You should have brought paper and pens, right?" said Xu Mang.

"Give. ”

Henry handed the paper and pen to Xu Mang, and after taking the pen and paper, Xu Mang began to help solve the problem.

Of course

In order to speed up, Xu Mang shamelessly began to cheat.

Boom,

soon

Only the remnants of the arm and the marks left by the tip of the pen were seen.

“？？？”

“？？？”

“？？？”

This... What's going on?

Hulai?

Henry and Joseph couldn't see what he wrote on the paper because they were far away from Xu Mang, so they blew up on the spot, thinking that Xu Mang was bluffing them, and it was impossible for ordinary people to be as fast as this, which was obviously nonsense.

"This..."

"What is this doing?" said Joseph angrily.

"Shh

"Don't disturb Professor Xu!" Matley didn't have a good impression of the people in the mathematics department, glanced casually, and said coldly, "Sit well, don't talk." ”

The graffiti continues,

still maintained the original speed, but Henry and Joseph couldn't hold back their curiosity, stood up cautiously, and took a closer look at what Xu Mang wrote on the white paper, and as a result, this look made them completely doubt their lives.

The calculation process?

It's full of calculations!

The two of them were a little at a loss, although they knew that this problem was difficult for Xu Mang, and it would definitely be solved by him, but it was just a matter of time, but this time was inevitably too fast, right?

Don't...

Is what Dean said true?

Does Professor Xu really have such a fast speed?

"Henry?"

"It's... It can't all be true, right?" Joseph looked at his companion in horror: "How can it be so fast?"

"I don't want to take it either. ”

"But..."

"In reality, he's so fast. Henry smiled bitterly: "How did he manage his brain and arms, work so quickly, and the key can match each other." ”

This question,

There was no answer.

Of course

These foreigners came into contact with Xu Mang for the first time, and they didn't know his nickname in China, known as the invincible unicorn arm fast gunner, what they said was that Xu Mang was unreasonably fast, and sometimes he would be long, such as when he was with Xiao Man.

Time flies,

finally

Xu Mang completely solved this partial differential equation, to be precise, it is a system of equations composed of multiple second-order nonlinear partial differential equations.

"Solved!"

"Oops... My hands are so sore that I can't do it. Xu Mang moved his arm, not to mention... Since the qualitative change with Xiao Man, the flexibility of his arms, including his fingers, is far less than half of what he used to be, and he is sore at every turn.

Where was this case before...

“...”

“...”

“...”

Then

The scene was silent, and the five of them all looked at Xu Mang in horror, looking at the contents of his five blank sheets.

Finish... Done?

Was it just done?

Is this still unreasonable?

"Huh?"

"Look at your expressions are a little frightened?" Xu Mang said with a smile: "Don't be like this... It's just that you guys don't know about me, in fact, it's all normal operation, so what... I went first, a little tired. ”

Words fall,

Xu Mang left directly.

Several people looked at the back of Xu Mang's departure, and did not react for a while, and when their consciousness returned to their brains, they found that the person was gone.

"How?"

"I'll just say that Professor Xu is different from others, he is very fast, fast to the point of collapse. Mattley said indifferently, "Henry, Joseph, have you seen it?"

There was no answer,

At this time, the two were proofreading Xu Mang's calculation process, and to their surprise, there was no shrinkage in the process at all.

"I..."

"What have I just been through?" said Henry to himself, "How did you do that?"

Joseph is the same problem, and it is simply impossible to understand why.

Dean, Bill, and Matlie didn't speak, just sat quietly in their seats, looking at the two math professors with skeptical expressions.

And then

A slight smile appeared.

...

Following

Henry came to the office with the process that Xu Mang had completed yesterday, and when he pushed the door in, he was surrounded by his colleagues.

"How?"

"Didn't Professor Xu finish it in half an hour?"

The owner of these words is the one who provided the question, and he is most concerned about the result of yesterday afternoon, after all, this mathematics professor is the kind of person who does not believe that Xu Mang can solve this partial differential equation in half an hour.

"Ugh..."

"Yesterday I experienced the most miraculous moment of my life. Henry recalled yesterday's experience and couldn't help but smile bitterly: "This has had a great impact on my life values. ”

“？？？”

“？？？”

“？？？”

What's the situation?

What the hell is going on here?

This is the calculation process written by Professor Xu. Henry took out a stack of papers, handed it to the math professor, and said solemnly, "Look at it, the process is right." ”

moment

A group of people began to study Xu Mang's calculation process, and after a few minutes, everyone agreed that there was no problem with the process.

"Henry, these contents... How long did it take Professor Xu?"

"How much time did it take?"

"Let's announce it soon. ”

Faced with a tidal wave of inquiries, Henry shook his head and sighed, "Maybe you don't believe the time I'm talking about, but... That's the truth, there's no such thing as falsehood, he... It's just less than that..."

"In less than half an hour, all the calculations were completed. ”

As soon as the voice fell,

There was a dead silence in the office, and even the air condensed in silence.

This...

I...

It was really solved in less than half an hour?

Regarding this problem, whether Xu Mang can solve it, no one doubts this, what they question is time, what Dean said before is fifteen minutes to solve, it sounds ridiculous, I never thought that more ridiculous things are still to come.

At this moment,

No one could laugh.

At this point,

In the office came an old man, who was an authority in the field of mathematics.

"What's wrong with you?"

.......
