I really don't want to lie down and win

quickly,

This flame of fighting spirit is a little dimmed,

It's so hard...

"Hey?"

"Old Yi!"

"I have a problem where physics is now described as a mathematical equation, let's solve it together!" Zhang Yaying said: "Please help me find out what kind of physical phenomenon this is. It seems to be a problem of extreme space-time curve description."

"Uh?"

"Have you studied physics?" The other party said with a smile: "Show me!"

moment,

This old Yi called Zhang Yaying back with a very serious tone.

"Old Zhang!"

"Who are you helping to solve this problem?" Lao Yi asked: "This problem is not ordinary...From the point of view of understanding, it involves the concept of four-dimensional space-time...and it has a shape...This... The other party is not an ordinary person, right?"

"..."

"It's Xu Mang."

"He was at the mathematics competition training base, and then he gave such a problem to the contestants, and he solved it within four hours, and at the same time asked anyone to help." Zhang Yaying said helplessly: "I think this is a challenge to us. "

"he?"

"He asked your contestants to solve this problem?" Lao Yi said confusedly: "This is obviously aimed at your mathematics department!"

"In that case..."

"Then I can't help anymore!" Lao Yi showed a smile: "But I can't solve it, you can find a way yourself, this has completely divorced from physics, it is a purely mathematical problem, very pure...so pure No knowledge of physics is required."

hang up the phone,

Zhang Yaying fell into silence. If he was given a few days, he might be able to solve it, but it is only four hours, so harsh that he cannot speak, it is very unfair... unless the equation of this problem is extremely simple.

is it possible?

The question Xu Mang gave couldn't be addition, subtraction, multiplication and division.

quickly,

Zhang Yaying found several other professors in the Department of Mathematics to study this problem together. However, after half an hour, the conclusion was that it could not be completed in a short time. It would take at least two weeks or even use a computer.

"Academician Xu Mang has created a problem for our Department of Mathematics!" A certain professor sighed, "He has been thinking of doing this for a long time, right?"

"he..."

"It's hard to say... Although there is no intersection, but I heard from other people that Academician Xu Mang is quite strange." Another professor said: "He seems easy-going, but he is very stubborn and has a bad temper. Listen Said that he rejected many preferential policies for him."

"He has the capital to refuse." Zhang Yaying opened his mouth and said: "Won the Nobel Prize in Natural Science at such a young age, and it is the first natural science prize in our country, plus his age... I still can't see His height, because now is just the beginning."

"All right!"

"Let's continue!" Zhang Yaying said solemnly: "Our Department of Mathematics at Peking University is number one in the country, and we cannot be defeated by a physics student."

At this time,

I don't know who leaked this problem. The students in the entire mathematics department have fallen into a crazy stage because of this problem. After all, it was proposed by Xu Mang. If anyone can solve it, then this person will definitely be among the experts. Stand out in the Department of Mathematics.

Many people took this opportunity as a stepping stone to their own success, but unfortunately... they overestimated their own strength, and at the same time underestimated Xu Mang's bitch attributes. Facing this temporarily unsolvable problem, many people collapsed up.

The former Four Great Talents were already far away in the United States, and the current Four Great Talents, except for two who entered the national team for the math competition, the other two were sitting together in the library, solving math problems provided by Xu Mang.

And the collaboration of these two people has attracted the attention of many students. Although the so-called four great talents are a kind of joking name of everyone, they don't have the corresponding strength, and even the joking names are mixed up. These four people almost represent Beijing. The highest level of knowledge in the Department of Mathematics.

but...

The two were already in despair at the training base, and the other two were not much better. They couldn't find a solution even after hard thinking and meditation. Although they understood the physical phenomenon, they...couldn't describe it.

this day,

The Department of Mathematics of Peking University experienced the darkest four hours, and no one knew what to do next.

And in Fuda,

Xu Mang's alma mater,

Fuda Mathematics Department was the second largest in the country, but their performance was mediocre. After knowing that Xu Mang had provided such a problem, almost no one could not think hard enough to solve him. The legend of Xu Mang was still circulating in the school.

Director Ouyang Fei looked at a question on his computer screen with a helpless smile on his face. Xu Mang... was so messed up, what was he thinking?

this day,

these four hours,

Everyone is thinking about a question.

How to solve it?

......

Chapter 897 What happened here?

A cafe in Beijing,

Yang Xiaoman is sitting in a private room drinking coffee and chatting with a few young and beautiful women. These people are all her business partners. They borrow the opportunity of coming to the capital to increase their mutual affection. .

"Xiaoman?"

"Tell us about your husband?" A young woman asked with a smile, "Seriously...everyone in the circle knows that your husband is Xu Mang, and he is a great scientist...but There is really too little news about your husband, it is basically reports that we cannot understand."

"Yes!"

"Talk to us." Another woman smiled and said, "Gossip, gossip."

Facing the curious people, Yang Xiaoman thought for a while, in fact, it’s nothing to talk about big pig’s hooves, and then said: "It’s ok... My husband is just an ordinary person, because in the field of scientific research Zhong is too amazing, and then blow him up to the sky."

"but..."

"He has the capital to boast." Xiaoman said seriously.

"..."
