Ultimate Scholar

When he first went to Peking University, Li Mu joined Li Ruyu's tutor, Academician Chen Shanping's research group on cancer and immune system, mainly to provide mathematical help.

After all this time, his help was finally needed.

"good!"

Hearing Li Mu agree, Li Ruyu nodded, then left the room and came in with a lot of materials.

"The data about the experiment is all on these, if you have any questions that you don't understand, just ask me."

"Um."

Li Mu took the materials and put them on the desk he had packed.

While looking at these materials, he asked, "Didn't you say last time that Academician Chen specially arranged a project for you? How is your project going?"

Speaking of this matter, Li Ruyu's face showed complacency: "Hehe! Once my subject is released, I'm afraid it will scare you, and I will definitely post it to the next section."

Li Mu thought about the fact that the quality of his graduation thesis must be at the level of the first district...

Finally, he shook his head and said with a smile, "Yeah, that's amazing."

"If you have any questions, especially in mathematics, you can ask me."

"Thank you." Li Ruyu waved his hand: "But I don't need mathematics for this subject yet, I can do it by myself."

Li Mu smiled: "Okay, that's good."

This is the sister who will be strong all her life?

Without saying any more, he looked at the data seriously.

This project explores the mechanism of interaction between cancer cells and the immune system, especially on lung cancer cells.

The immune system of the human body is very powerful. Immune cells can recognize cancer cells and attack them. Therefore, there is a saying in the biological world that everyone has cancer cells, and the small amount of cancer cells in normal people are destroyed by immune cells. identified and killed.

However, for those patients who have too many cancer cells and have already suffered from cancer, the immune system seems to be a little weak, and the most important thing is that the morphology of cancer cells is not much different from normal cells, and at the same time, the function It can also actively avoid being recognized by immune cells.

Therefore, how to find the key point where cancer cells can be recognized and attacked by immune cells can help biologists find a solution to cancer.

But because there are various differences among different cancer cells, they only discuss one type of cancer cell, lung cancer cell, in this project. \b

Of course, considering the number of lung cancer patients in the world, the value of this topic is definitely not small.

"These experimental data mainly come from the co-existence of immune cells and lung cancer cells in a petri dish."

"We marked the surface of cancer cells and counted various elements in the culture dish, such as metabolites and so on."

"The amount of data is huge, and it is very troublesome to analyze, especially the cancer cells in the cancer cell clusters are not always recognized by immune cells, making it difficult for us to analyze what is playing a key role in the process."

"So need your math help."

While Li Mu was watching, Li Ruyu beside him also introduced the specific situation to him.

Listening to Li Ruyu's introduction, Li Mu nodded slightly, but didn't say anything.

Looking at so much data in this thick data, it is enough to show that the experiment scale of this research group is very large, and it is no wonder that it took so many months to come to him.

There are dozens of groups, and each group has hundreds of data.

Still, the more experimental data, the better for him.

Because, for others, too much data may be more complicated, but he has a brain computer, but he can easily analyze such a huge amount of data.

Quickly took out the pen, and he began to calculate.

Still the same as before, use the principles of probability and statistics to process these data. \b

Statistics play a vital role in many disciplines, such as biostatistics in biology, and statistical mechanics in physics. \b

While calculating, Li Mu was also thinking about related issues in his mind.

Time passed slowly, Li Mu was calculating on the pen, and the computer in his mind was also calculating.

Until the end, his heart suddenly moved, but he thought of the problem he was researching in his mind.

"Quantum statistical mechanics... The mass of the W boson is equivalent to a balanced system, and this mass obviously evolved from a non-equilibrium system."

"In a non-equilibrium system, there must be a key that causes the mass of the W boson to vary."

"So... use reverse quantum statistics to find the reason from the result..."

Suddenly he realized something, and then the pen that was analyzing and calculating these biological experiment data stopped, started a new line, and wrote down his preliminary thoughts on the reverse quantum statistical method.

Li Ruyu next to him immediately became confused.

She has been watching Li Mu's calculation process, trying to learn something from it, such as Li Mu's thinking.

Being poor in mathematics has always been her pain, and now that she saw her younger brother becoming a world-renowned mathematician, she wondered, everyone was born by the same mother, so couldn't her own mathematics be saved?

So she also strengthened her study of mathematics, especially those related to biostatistics, so when Li Mu wrote it just now, she could barely understand it.

As a result, these things that Li Mu suddenly wrote...

What the hell is it?

She asked in a low voice: "What part of probability and statistics are you writing now? Why haven't I read it?"

"Oh, this, this is quantum statistical mechanics, it's normal for you not to understand."

Li Mu replied. \b

"ah?"

Li Ruyu's eyes widened immediately: "Do we still need to use quantum statistics for our biostatistics?"

don't!

This simply killed her!

Li Mu couldn't laugh or cry for a while, and quickly explained the reason. He just wrote it because he temporarily thought of the content of quantum statistical mechanics, and it had nothing to do with their topic.

Li Ruyu breathed a sigh of relief.

Almost startled her.

"Then do you have an idea about our data?"

Li Mu narrowed his eyes and pondered for a moment, and finally said: "A-23, A-45, A-89... I suggest that you repeat the experimental data of these groups several times, carefully observe the reaction process, especially It's the details."

Performing calculations on paper is actually just his habit. No matter what he is thinking, the computer in his mind will give full play to its ability to multi-task and perform multi-threaded analysis. Therefore, in such a short period of time, he has already analyzed all the data. over and over.

Just kidding, at the Institute of High Energy, the six-figure data volume has been analyzed, and the data on their side is only a thousand, so there is no challenge at all.

So, he reported the numbers of more than 30 sets of data in a row, and Li Ruyu next to him quickly took out a paper and took notes.

After writing it all down, she asked curiously, "What's wrong with these data? Is there any difference?"

"According to the analysis, in the experimental data of these groups, there are obvious differences from other data."

"There is a difference?" Li Ruyu glanced at the data of these groups, isn't it composed of ten numbers?

Where is the difference?

Li Mu glanced at her: "You want to hear it?"

Li Ruyu nodded like a chicken pecking at rice: "Yes!"

If you know what it is, you must also know why it is. Li Ruyu has always held this attitude in her studies.

Li Mu just smiled: "Okay, I will explain it to you briefly."

Then he picked up the paper and pen and began to write.

"I don't understand biology, but since these numbers appear here, there must be reasons behind them, and there will always be subtle differences in them."

"For example, the metabolite indicators of the B-112 group of data, you may look no different from the metabolite indicators of other groups. The difference in numbers seems to be just the same error, but if we analyze the data of these groups , you can easily find the difference.”

Li Ruyu: "...Really?"

Li Mu: "Then I'll do the math for you again."

Li Ruyu: "Good!"

...

After an unknown amount of time, the door of Li Mu's room opened, and Li Ruyu left the room in a daze. \b

God, what was she thinking just now, trying to understand Li Mu's thinking?

Although she remembered what Li Mu said, she didn't understand the meaning at all.

This kid, he still doesn't admit that he is specialized in writing heavenly scriptures!

Of course, she didn't understand the process, but she generally understood the conclusions given by Li Mu. All the data Li Mu pointed out had significant immune reactions.

In other words, if they repeat these experiments carefully, they will likely discover how the immune system recognizes and attacks lung cancer cells!

She was excited, this is what their research team wanted to know!

Although she only came back today, she didn't have any intention of resting. She quickly returned to her room, then contacted Academician Chen Shanping and told him the news.

Li's mother, Qin Lan, was helping her daughter clean up the room at home. Seeing this scene, she could only say: "Don't tire yourself out."

Li Ruyu waved his hand: "Just don't worry!"

It didn't take long for the video conference to begin.

Except that she went home early at the request of Chen Shanping, everyone else in the research group was still in the laboratory.

So as soon as the video conference was turned on, she saw all the colleagues in the laboratory appearing in front of the camera.

"Ruyu, you haven't been home for long, have you? Li Mu has finished analyzing our experimental data now?"

As soon as the video was opened, Li Ruyu's best friend Xin Xin was the first to ask a question.

Of course, this question is also what everyone in their laboratory wants to know.

No matter how you think about it, it's impossible, right?

However, Li Ruyu just nodded and said, "Yes, he should have almost finished his analysis."

There was a sound of "Huh?" in the conference room.

With so much data, how can we analyze it so quickly?

Are you hanging up?

Chen Shanping's expression in the laboratory was also very surprised. They collected data for several months, but Li Mu analyzed all of them in one day?

But soon, he said: "Okay, let's not talk about this matter, how is the analysis?"

In any case, the result is the most important.

Li Ruyu directly sent the numbers of the more than 30 sets of experimental data that Li Mu mentioned.

"According to Li Mu's analysis, he suggested that we repeat these experiments several times to observe the reaction process of immune cells and lung cancer cells."

"Is there anything wrong with these groups' experiments...?"

Everyone in the conference room became puzzled, just like Li Ruyu's performance before.

Li Ruyu smiled, just now she had experienced that kind of bewilderment, and of course let these fellow students experience the same feeling now.

"Are you sure you want to know the reason?" She made a fool of herself first.

However, Chen Shanping directly interrupted her thoughts: "Don't talk nonsense, just speak directly."

The instructor was dissatisfied, Li Ruyu stuck out her tongue playfully, and then honestly explained the process that Li Mu had just explained to her fellow disciples.

Even if she couldn't remember it, she took notes, but she was able to recount it completely.

It's just that during the process of her retelling, there was some silence in the conference room.

Uh... It seems that there is really no need to listen to the analysis process?

Chen Shanping didn't speak either, feeling a little embarrassed.

However, he still said to other people in the laboratory: "Listen carefully, and study Li Mu's analytical thinking. Maybe the mathematics expert in our laboratory will be one of you in the future."

The graduate students in the laboratory immediately rolled their eyes wildly.

cpu!

It's definitely on the cpu for them!

How can this be learned?

But there is no way, the instructor said so, they can only listen to it honestly, and take notes at the same time.

In this way, Li Ruyu's narration continued. Although they couldn't understand the process at first, they finally understood when the final conclusion was presented.

Under very detailed analysis, these seemingly ordinary experimental data revealed very prominent differences.

It clearly told them that these experiments are likely to hide the answers they want.

"very good!"

Chen Shanping's eyes showed excitement.

After several months of experimentation, now we finally see the dawn of harvest!

Of course, this is also thanks to these analysis results. If they hadn't seen it with their own eyes, they wouldn't even believe that these data could be analyzed so minutely.

"Li Ruyu, thank you for your hard work, and by the way, thank you to Li Mu for me."

Chen Shanping said solemnly.

"good!"

Hearing Academician Chen's words, a smile appeared on Li Ruyu's face.

Brother, awesome!

There was almost no nonsense, and Chen Shanping immediately arranged the next work: "Next, we will repeat these experiments several times until we find the reason for the abnormal appearance of these data!"

"yes!"

Everyone in the lab responded immediately.

"In addition, Ruyu, you should take a good vacation, and I have worked hard for you."

Li Ruyu laughed and said, "It's not hard work, it's not hard work."

Just give her a few extra days off.

As a result, Chen Shanping said at the next moment: "Then we will go back to the laboratory in the fourth year of junior high school to complete this experiment, is it okay?"

Li Ruyu's face suddenly became depressed: "...no problem."

The fourth day, the fourth day!

It means that she will go back to school in three days this year.

A certain great god said that the 21st century is the century of biology. Looking at it now, the 21st century is completely a tragedy for biological dogs like them.

...

Time passed like running water.

A week passed quickly, and Huaguo also ushered in the new year of 2021.

What is the relationship between science and tradition, Li Mu can't say, but at least he can feel the faint joy during the New Year, even if people say that the taste of the New Year has faded now.

The first day, the second day, the third day, the three days passed quickly, and on the fourth day, Li Ruyu embarked on the journey back to Beijing.

"No one will go back to school before the end of the year, no, no?"

Li Mu personally sent his sister to the airport. Of course, before parting, he did not forget to laugh a few words.

Li Ruyu glared at him, "Finding faults, isn't it? Besides, it's impolite."

Ever since Li Mu knew that she was going back to school early, he would laugh at her every day.

Li Mu smiled, and then handed the suitcase to Li Ruyu: "It's the security check, go there, remember to call when you arrive."

"Yeah." Li Ruyu nodded, took the suitcase, and said: "Be careful when you go to England, don't go to those weird bars, especially places where men gather."

"Especially don't go to Brighton, it's scary to hear it's called the gay capital."

"You don't want our parents to raise children, do you?"

Li Mu: "...What are you worrying about all day long? Hurry up, hurry up."

As he spoke, he pushed Li Ruyu over.

Soon, after watching his sister go through the security check and waving goodbye to him, he also turned and left.

After the new year, he is indeed going to Oxford University.

He thought about what Li Ruyu said last, and he couldn't help but gasp, as if what he said really made sense?

It's time to pay attention.

...

The New Year's time passed quickly, and Li Mu stayed at home until the Lantern Festival.

On January 16th, he will leave.

However, on the night of the 15th, he received an unexpected call.

Edward Witten.

"Li Mu, when I used Li's expansion to perfect the M-theory and tried to make it backward compatible with the low-energy theory, I encountered almost insurmountable difficulties."

"I need your help."
