High Ridge Flower Rescue Project

'A variety of methods are used in the solution of mathematical problems.For example, cohomology can be used as a tool when measuring the flow and flux on the boundary of the relevant surface. '

Lu Huizhou lowered his head, the black ink pen rustling on the blank A4 paper.His expression was very serious, his brows were slightly furrowed, and he seemed extremely unapproachable.

In the paper that Lu Huizhou got, there were not only purely mathematical problems, but also some problems related to physics that could be solved by mathematical means.

That's why Lu Huizhou spent so long looking through the materials in the library.

Ever since Zhang Zibo came back, he saw Lu Huizhou buried in writing something, and when he was about to go to bed, Lu Huizhou was still writing there.

For four or five hours, Lu Huizhou didn't seem to get up from his seat.

Zhang Zibo couldn't help but glanced over curiously, "What are you writing?"

Did he remember that he didn't have so many homework today, or did he say he missed it in class?

As a result, after Zhang Zibo glanced at the densely packed equation letters on the paper, he found that this was not what they were learning at all.

"You found the topic yourself?"

Zhang Zibo stood behind Lu Huizhou and watched for a while. Although he also majored in mathematics, he chose this major because he was young and ignorant.

Anyway, after the first week of school, he already wanted to change majors.

He used to be No.2 in Mathematics Olympiad. He once thought that he was very talented in mathematics, but after entering A University, he realized that he was completely overthinking.

He is a little clever at best, and has nothing to do with talent.

Not to mention the other god-level figures who have long been famous in major competitions, let’s just talk about this Lu Huizhou. As a celebrity in their A University, he is also one of the few students in the Department of Mathematics who passed the college entrance examination. Zhang Zibo originally thought that No matter what I do, I will not be worse than Lu Huizhou.

But this kind of thinking completely disappeared after the last exam results came out.

Lu Huizhou has been working part-time and Zhang Zibo knows it. As a roommate, Zhang Zibo knows best, but how much time Lu Huizhou spends on studying every day.

Not at all, but definitely not a lot of time.

In this way, the last time there were three students with a score of 90 and above in the entire mathematics department, Lu Huizhou was one.

This shocked the jaws of many people.

The other two were already famous when they were in high school competitions. It is not surprising to get a score of 90+, but Lu Huizhou?

Lu Huizhou is most famous for entering University A because of his face.

Before that, many people even regarded Lu Huizhou as a beautiful vase with an empty head, and they once discussed in private that if a student like Lu Huizhou studied liberal arts, he should be very popular with girls, after all, his appearance is there. Just a few sour poems can earn a reputation as a wit.

But what do you say he came to the mathematics department full of old men?

Moreover, Lu Huizhou is not very talkative, and he is always troubled by a lot of troubles, so people in the mathematics department don't like to play with him very much, and naturally it is impossible to know much about Lu Huizhou.

But since the results came out last time, the way they looked at Lu Huizhou was different from before.

They all felt that this girl is also a hidden one, and she is sloppy!

However, Zhang Zibo, who was on the verge of failing the exam repeatedly, said that it was not scientific at all!

But after that, Zhang Zibo subconsciously paid more attention to Lu Huizhou's matter.

For example, now—

Lu Huizhou had piled up about a dozen sheets of A4 paper in his hand.

After you have ideas about these topics, it is very easy to write them again, just follow the steps one by one.

Therefore, Lu Huizhou didn't feel bored or tired sitting there at all, but felt very comfortable.

After hearing Zhang Zibo's question, Lu Huizhou thought for a while, this test paper was really found by himself.

So nodded, "Yeah."

Zhang Zibo shook his head in admiration, "Do you usually take this kind of questions in practice?"

Although he can probably understand some of the topics above, he has no idea at first glance, let alone ask him to write it.

Seeing that Lu Huizhou was still writing, Zhang Zibo sighed silently in his heart, and didn't pay much attention to this matter.

......

Professor Xu checked the handed-in test papers one by one.

He remembered clearly that a total of eight test papers were handed out, and now six have been handed in.As for why two copies were not handed in directly, Professor Xu was not surprised.

His questions this time were originally more difficult. The requirements for mathematical thinking and logical computing ability are relatively high, the amount of calculation is still very large, and the time given is relatively short, so it is normal for some people to fail to submit it directly. of.

Even in the submissions, there are many mistakes and omissions.

Although Professor Xu didn't speak at this time, everyone could see that he was not satisfied with the results in front of him.

He pushed his glasses, and was already considering whether to release the news and investigate a few more people.

After reading all five test papers, only one made Professor Xu feel barely satisfied.

The last one left.

Professor Xu took a sip of tea, stretched his muscles and bones a little, and took the last portion casually.

At this time, another professor from the Department of Mathematics opened the door and walked in. He smiled as soon as he entered, "I said, Lao Xu, you haven't found your assistant yet?"

The professor picked up a paper that he had already read and glanced at it, "Ding Han? I know this student, he is quite a spiritual young man. He has published two papers on differential geometry. Although it is not a core journal, But it’s pretty good.”

Professor Xu said while looking at the information in his hand, "So far, only this one is still usable, and the others are almost ready."

As he was talking, Professor Xu suddenly let out a soft snort.

Then, the originally casual expression became serious.

This way of solving the problem is quite interesting...

The other person who was here to watch the fun came over very naturally, "Found another one?"

He didn't see how it was doing, but looked for the name immediately.

"Lu Huizhou?" Is there such a student in their mathematics department?

The professor smacked twice in his heart, but suddenly he seemed to have a flash of inspiration, "Lu Huizhou!"

He couldn't help but asked Professor Xu in surprise: "You even gave the freshman a question?!"

Professor Xu was looking at the topic, without raising his head, and asked, "What freshman? Let me tell you, Lao Li, this student is quite interesting... Look at him, I didn't even think about it." This problem can actually be solved in this way, and it is much simpler..."

Professor Xu didn't notice at all that when he said this, Professor Li was looking at him with a very surprised and strange look.

"Has he solved all five questions?"

Professor Li knew the difficulty of the questions that Professor Xu asked, and he even helped to solve one of them.

It's good that their mathematics department has a few good seedlings this year, but among them, is there Lu Huizhou?

Professor Li thought with some uncertainty.

"Come on, see for yourself."

Professor Xu directly handed over the part he had finished reading.

Professor Li quickly put on his own reading glasses, and then squinted his eyes to look at each line.

After reading it, Professor Li stopped talking.

At this time, Professor Xu also finished reading the remaining part, and only then did he think about asking other questions, "What did you want to say just now?"

Professor Li flipped through the paper in his hand, with doubts in his eyes, "Is this really written by Lu Huizhou?"

Professor Xu was startled, "What? Do you suspect that this student is cheating?"

Professor Li shook his head hesitantly, nodded again, and finally spread his hands, "Oh, do you know that this Lu Huizhou is a freshman this year?! Is this the level of a freshman?!"

......

"Already handed over?"

"handed in."

Xi Hua breathed a sigh of relief, and looked more nervous than Lu Huizhou, "That's good."

Lu Huizhou walked beside Xi Hua.

It had just rained last night, and the soil was still wet.

There were many fallen leaves from the trees on the gravel road, and a slight chill could already be felt in the air.

Xi Hua had already put on the windbreaker, and Lu Huizhou was still wearing only a thin long-sleeved shirt. Xi Hua couldn't help frowning, he stretched out his hand from his pocket, and said to Lu Huizhou:

"Give me your hand."

Lu Huizhou looked at him in confusion, and after hesitating for a while, he obediently passed his hand over.

"what happened?"

Xi Hua held Lu Huizhou's hand, feeling cold in his palm.

At this time, Lu Huizhou seemed to have finally realized Xi Hua's intentions, and couldn't help but wanted to withdraw his hand.

Xi Huaqiang resisted the urge to sigh, and simply held Lu Huizhou's hand and put it in his coat pocket to warm up first.

"Don't you know it's cold?"

Lu Huizhou was shocked by Xi Hua's natural and intimate movements.

The other party's pockets carry the residual warmth of his body, and the hand holding his own is even more...

Lu Huizhou's fingertips flinched, and then he didn't dare to move at all.

There was no expression on Lu Huizhou's face, but the tips of his ears, which were quietly turning red, betrayed him.

He pursed his lips, his slender and thick eyelashes trembled slightly, and finally said softly: "I will pay attention next time."

Xi Hua smiled, but suddenly stretched out his hand to compare the heights of himself and Lu Huizhou, and then thoughtfully said: "We are about the same size, you are a little taller than me, but it's okay... "

Lu Huizhou blinked suspiciously.

Some fouled too much, Xi Hua couldn't help but want to reach out and rua the opponent's head.

Fortunately, Xi Hua finally restrained his evil hand that was about to move, and at the same time repented without sincerity in his heart.

With a smile on his face, he asked, "Are you okay today? Come on, I'll take you somewhere."
