Seeing that Lu Zhou hadn't started writing for a long time, Academician Lu asked with a smile.

"The first two questions have been made, why can't the last question be done?"

After staring at the topic for a while, Lu Zhou raised his head and asked, "Professor, have you studied string theory?" ”

"What I'm asking you to talk about is your own opinion, what do you care if I've researched it?" Academician Lu smiled and said, "You can just talk about it, don't care about my opinion." ”

Seeing that his careful thinking was seen through, Lu Zhou smiled embarrassedly, coughed lightly and said, "Then I'll say it directly?" ”

"If you think about it, just say it, it's the same whether you write it or not." Academician Lu said.

After thinking about it, Lu Zhou decided to answer this question from two aspects.

"I don't dare to say too much about it, so I'll just talk about my personal opinion. If it is about the development of string theory, I agree with Mr. Yang that physics is an experiment-based science. A theory that cannot be proven experimentally is only a mathematical representation, and its value is very limited. ”

"The core idea of string theory states that the basic unit of nature is not the point particle of electrons, photons, neutrinos, quarks, etc., but a very small one-dimensional string. And all elementary particles in nature are produced by the vibration of strings. But so far, our understanding of matter is still at the level of microscopic particles, and no one really sees the existence of that string. These assumptions are supported by seemingly beautiful mathematical formulas. ”

Academician Lu smiled and asked, "So you also think that it is useless to develop string theory?" ”

"Of course not," Lu Zhou replied with a shake of his head, "String theory is like a castle in the sky, but that doesn't mean that the pavilion in the air is useless. ”

Academician Lu's eyebrows raised with interest: "Oh? ”

"Just like the establishment of the Standard Model, many theories are based on conjecture, and as technology advances, these theories will one day be tested. String theory, on the other hand, may just have to wait a little longer. ”

After a pause, Lu Zhou smiled and continued.

What's more, human beings should not only have what is in front of them, but also poetry and distance. Isn't the study of quantum chromodynamics and even the Large Hadron Collider in Europe built to test the Standard Model? Even though we may not see it on this day, someday, someone will see the string for us. ”

There was silence for a while.

The index finger tapped lightly on the table, and after a long while, Academician Lu nodded slowly.

"Not bad."

Nice meaning over?

Just in case, Lu Zhou still asked.

"Professor, have I passed these three questions?"

Academician Lu smiled and commented.

"Of course. The first two objective questions are completely correct, and it can be seen that you have really put in some effort in the past two months to listen to the things I taught you. ”

Lu Zhou: ???

Wait, you've taught me these two months?

Not noticing the question marks on Lu Zhou's face, Academician Lu paused and continued.

"As for the last question, I said that it is a sub-question, and the discussion of academic issues is originally to speak freely, not to follow the crowd. No matter what you answer, as long as it makes sense, I will count you. ”

Lu Zhou smiled embarrassedly, and then asked, "Professor, will you take me to Switzerland?" ”

Academician Lu smiled and nodded: "Of course, I will prepare the relevant documents for you, and you can go and handle the visa issue as soon as possible in the next few days." ”

"Thank you, Professor!"

"You're welcome, that's what I promised you," Professor Lu smiled, paused for a moment, and continued, "By the way, I'll ask you something. ”

Lu Zhou asked, "What's the matter?" ”

Academician Lu: "There are still a few interns in the LHCb Huaguo Research Group, do you have any interest in learning about them?" ”

Hearing this, Lu Zhou was stunned.

Just now he was still thinking about how to open his mouth to Academician Lu and let him sneak into the LHCb to touch the fish, but he didn't expect happiness to come so suddenly......

……

LHCb is an abbreviation for Bottom Quark Detector and is an international research organization. Just like the BESlll International Cooperation Group, which is named after the abbreviation of the Beijing spectrometer, it is led by a country or an organization, and researchers from many countries participate in the joint completion of a scientific research project.

At present, the focus of LHCb research is to find the pentaquark state particle "Pc+".

According to a large number of experiments and calculations, although it is not certain what exactly this particle is, it can be known through the invariant mass spectrometry analysis of J/ψp that the mass of this particle is around 4.5 GeV.

However, it is a pity that the Shangjing Positron Collider used by the Beslll International Cooperation Group led by China has an energy region between 1-4.5GeV, which happens to be stuck in the lower limit of the mass threshold of "Pc+".

In order to produce "Pc+", at least 6GeV of energy is required.

Therefore, it is a pity that this time, Chinese researchers can only participate in the work of the LHCb cooperation group as collaborators, to find the exciting and mysterious particles.

The Huaguo Cooperation Group is mainly led by Professor Gao of Mizuki University, and major universities in China also participate. Academician Lu is also one of the leaders of the Huaguo Cooperation Group, and his work is mainly to analyze the measured bottom baryon cross-section.

Lu Zhou joined the Huaguo Research Group as an intern, and no matter what role he played, he at least participated in this historic work.

Lu Zhou was quite excited about the fact that he was about to witness history.

Of course, what excites him even more is that he doesn't know how much physics experience this experiment can bring him.

Anyway, this is a moment to witness history, and it must be more exciting than the mathematical conference in Princeton, right?

Fifty thousand?

Lakh?

If only he could get his physics up to LV3 as well.

Just then, Shi Shang's voice interrupted his delusion.

"Elbow, what are you laughing at?"

Realizing that he seemed to be laughing, Lu Zhou, who was applying for a visa on the computer, covered it up with a cough: "Ahem, it's nothing, I just thought of something interesting." ”

Walking over and glancing at the computer screen, Huang Guangming said in surprise: "Passport? Are you going abroad again? ”

Lu Zhou nodded: "Yes, about the beginning of May, I will go to Switzerland with Academician Lu." ”

Liu Rui, who was brushing the question, shouted: "666"

For all kinds of manipulations on the elbow, he is about to form a conditioned reflex.

Sometimes, he is quite desperate for himself like this.

Huang Guangming was suddenly shocked: "Fuck, go to Europe to pretend to be forced this time?" Or a math conference? ”

Lu Zhou smiled and said in a low-key manner: "It's not mathematics, this time it's physics." And what is called pretending, I will do a lot of miscellaneous, mainly listening to the boss go up and speak. Even if you want to pretend, it's not my turn to pretend. ”

Huang Guangming looked incredulous.

At this moment, Shi Shang suddenly said in an embarrassed tone: "That Brother Lu, can I ask you for a favor?" ”

"What's the matter, let's talk about it." Lu Zhou said generously.

Shi Shang smiled embarrassedly: "Can you help me bring something back from Switzerland?" ”

Lu Zhou: "What's it?" ”

Shi Shang thought for a moment and said, "Farmman's cosmetics...... It seems to be called this brand. ”

Huang Guangming was shocked again: ", Brother Fei, do you still use cosmetics?" ”

"Get out! ...... for a female ticket That, help me bring it when you come back, how much money I'll convert into soft sister coins for you. ”

"Okay, I'll bring it for you when I see it." Lu Zhou nodded.

It's not easy for him to do this kind of small thing.

But it's hard to go back to Europe, do you want to bring some souvenirs back?

What's in Switzerland? Swiss Army Knife? I don't know if I can take it on the plane......

Lu Zhou thought about it for a long time, but he didn't think of anything to buy.

After thinking about it, let's bring some milk powder to the family, Xiaotong is about to be in the third year of high school, and it is good to prepare for the college entrance examination to make up for the body.

He, who is an elder brother, can't help with anything else, so he can only help her.
