Long after seeing the Ark, Master Lu asked with a smile.

“The first two questions have been made, why can't the last one be given a sub-question? ”

Staring at the topic for a while, the ark looked up and asked: "Professor, have you studied string theory? ”

“What I'm asking you to talk about is your own opinion. Do you care what I've done?” Master Lu laughed, “you can just say whatever you want, don't worry about my opinion. ”

Seeing his own caution was seen through, the ark embarrassed himself and laughed, coughed softly and said, “Well, shall I just say it? ”

“If you think about it, just say it. It's the same on paper.” Dean Lu said.

Think about it. The Ark decided to answer this question in two ways.

“I don't dare to say too much, just talk about my personal point of view. If it's about string theory development, I agree with Mr. Yang that physics is an experiment-based science. A theory that cannot be proven in experiments, with only mathematical representations, is of very limited value. ”

“The core idea of string theory points out that nature's basic units are not dotted particles like electrons, photons, neutrinos, quarks, but tiny, tiny, one-dimensional strings. And all the basic particles in nature are caused by the vibration of strings. But so far, our understanding of matter is still at the microparticle level, and nobody really sees the string. Supporting these assumptions are just some seemingly beautiful mathematical formulas. ”

Master Lu asked with a smile, "So you also think that developing string theory is useless? ”

“Of course not," the ark shook its head and replied, "string theory is like an aerial pavilion, but it doesn't mean that an aerial pavilion is useless. ”

Master Lu's eyebrows picked it out with interest: "Oh? ”

“Just as standard models are built, so are many theories based on speculation, and as technology advances, these theories will one day be tested. And string theory, probably just needs to wait a little longer. ”

Paused for a moment, the ark laughed and continued.

“Moreover, humankind should have not only the meticulousness of its eyes, but also poetry and far-off places. Didn't research on quantum chromodynamics, and even large proton colliders in Europe, all set up to test standard models? Even if we may not see it this day, one day someone will see it for us. ”

Silent for a while.

The index finger tapped gently on the table, and after a while, Master Lu nodded slowly.

“Nice.”

Does that mean it's over?

Just in case, the ark asked.

“Professor, have I passed these three questions? ”

Master Lu laughed and commented.

“Of course. The first two objective questions are perfectly correct, and it turns out that you've actually worked a little hard in the last two months to listen to what I've taught you. ”

Ark:????

Wait, you've been teaching me that for two months?

Without noticing the question mark on the full face of the ark, Lou Courston went on to say.

“As for the last question, I said, it is a question of sending scores, and discussing academic issues is a matter of speaking freely, not of the cloud. Whatever you say, I'll count you in, as long as it makes sense. ”

The ark laughed with embarrassment and asked, "Professor, will you take me to Switzerland? ”

Master Lu nodded with a smile: "Of course, I will prepare the relevant documents for you. Go and get the visa questions done as soon as possible in the next few days. ”

“Thank you, Professor! ”

“You're welcome, that's what I promised you," Professor Lu laughed, paused for a moment and continued, “Yes, let me ask you something. ”

The ark asked, "What is it? ”

Dean Lu: “How many interns are missing from the LHCb China Research Group? Would you be interested to know? ”

When I heard that, the ark stunned.

He was just figuring out how to talk to Master Lu and let him get into LHCb and touch the fish. I didn't expect happiness to come so suddenly...

……

LHCb is an abbreviation for the DeQuark detector and a research organization of an international character. Like the BESlll International Cooperation Group, named after the abbreviation of the Beijing Spectrum Spectrometer above, a country or an organization leads a multinational scientific researcher to jointly complete a scientific research project.

At present, the focus of the LHCb study is to find the five-quark particle "Pc +”.

According to a large number of experimental and computational analyses, although it is uncertain what this particle is, it can be seen from the constant mass spectrometry analysis of JÄP that the mass of this particle is near 4.5GeV.

Unfortunately, however, the Beslll International Cooperation Group, led by China, uses the Shangjing Positive and Negative Electronic Collider, which is located between 1-4.5 GeV and is stuck to the lower quality threshold of “PC +”.

At least 6GeV of energy is needed to produce “PC +”.

So unfortunately, this time, Chinese scientists can only participate as collaborators in the work of the LHCb cooperation group to find that exciting mysterious particle.

The China Cooperation Group is mainly headed by a senior professor from Shui Wood University, with the participation of universities and universities in China. Academician Lu is also one of the heads of the China Cooperation Group, and the work done is mainly to analyze the bottom weights section.

The Ark joined the China Study Group as an intern, whatever its role, at least in this historic work.

The Ark is quite excited about the fact that it is about to witness history.

Of course, he was even more excited not to know how much physics experience the experiment would bring him.

Anyway, this is also a moment to witness history. Must be a lot more exciting than the mathematical conference in Princeton?

Fifty grand?

Hundred thousand?

I wish I could get his physics up to LV3.

At this point, Stone's voice interrupted his delusions.

“Elbow, what are you laughing at? ”

Realizing that he seemed to be laughing out loud, he was applying for a visa on his computer, and he covered it up with a cough: "Cough, nothing, just thought of something interesting. ”

I walked over and looked at the computer screen, and Huang Guangming was surprised: “Passport? You're leaving the country again? ”

The ark nodded: "Yes, about the beginning of May, I'm going to Switzerland with Reverend Lou. ”

Liu Rui screamed, "666.”

He's about to form a conditional reflex for all sorts of elbow crap.

Sometimes he's desperate for himself.

Huang Guangmington shocked: "Shit, go to Europe this time to dress up? Still having a math meeting? ”

Ark laughed and lowered his voice: “Not math, this time it's physics. And what do you mean," pushy "? I'm a mess, mostly listening to the boss. Even if I had to pretend, it wouldn't be my turn. ”

Huang Guangming's face disbelieved.

At this moment, Stuart suddenly said in an embarrassing tone, “Brother Lu, could you do me a favor? ”

“What a busy day, say it.” The ark was generous, he said.

Stuart was embarrassed and laughed: "Can you get me something back from Switzerland? ”

Ark: “What is it? ”

Stuart thought about it and said, "Farman's makeup… seems to be called this brand. ”

Huang Guangming shocked again: "Shit, Brother Fei, do you still use makeup? ”

“Get lost! Girls' tickets... Well, bring them to me when you get back, how much I'll convert into soft sister coins for you. ”

“Come on, I'll take it for you when I see it.” The ark nodded.

Things like this don't get too easy for him.

But it's rare to go back to Europe. Do you want to bring back some specialties?

What's in Switzerland? Swiss Army knife? I don't know if I can get on the plane...

The Ark has been thinking about it for a long time and didn't think of anything to buy.

Think about it. Bring some milk powder to your family. Xiaotong is about to become a senior, and his body is ready for the college entrance exam.

He can't help her with anything else, he can only help her with this.
