Professor Lu Shenjian noticed that Lu Zhou had not started writing for a long time.
Professor Lu Shenjian smiled and asked, "You solved the first two questions, why can't you solve the last one?"
Lu Zhou stared at the question for a while before he looked up and asked, "Professor, have you studied string theory before?"
"I'm asking you to talk about your own opinion, why do you care if I've studied it or not?" Professor Lu Shenjian smiled and said, "Just talk about it, don't worry about my opinion."
Lu Zhou smiled embarrassedly and said, "Then I'll just say it?"
"Just say it. It doesn't matter if you write it on paper or not," said Professor Lu Shenjian.
Lu Zhou thought for a bit and decided to answer this question from two perspectives.
"I don't dare to say too much, so I'll just talk about my personal opinion. If it's about the development of string theory, I agree with Mr. Yang. Physics is a science based on experiments. A theory that can't be verified in experiments and can only be expressed in mathematical terms is of limited value. "
"The core idea of string theory states that the basic unit of nature is not electrons, photons, neutrinos, quarks, and other point-like particles. Instead, it is a very small one-dimensional string. All the basic particles in nature are produced by the vibration of the string. However, our understanding of matter is still at the microscopic particle level. No one has actually seen the existence of the string. These assumptions are only supported by some seemingly beautiful mathematical formulas. "
Professor Lu Shenjian smiled and asked, "So you also think that developing string theory is useless?"
"Of course not," said Lu Zhou as he shook his head and said, "String theory is like a castle in the air, but it doesn't mean that the castle in the air is useless."
Professor Lu Shenjian raised his eyebrows and said, "Oh?"
"Just like the establishment of the standard model, many theories are also based on conjectures. With the advancement of technology, these theories will one day be tested. String theory, on the other hand, might just have to wait longer. "
Lu Zhou paused for a second before he smiled and continued.
"Not to mention, humans shouldn't just live in the present, they should also live in the future. Wasn't the research on quantum chromodynamics and the Large Hadron Collider built to test the standard model? Even if we might not be able to see it today, one day, someone will see that string for us. "
There was a moment of silence.
Professor Lu tapped his finger on the table. After a while, he slowly nodded.
"Not bad."
Does not bad mean I passed?
Just in case, Lu Zhou asked.
"Professor, do I pass these three questions?"
Professor Lu Shenjian smiled and commented.
"Of course. The first two objective questions were completely correct. I can see that you've really put in some effort in these two months. You've listened to what I've taught you. "
Lu Zhou:???
Wait, you taught me in the past two months?
Academician Lu didn't notice Lu Zhou's confused expression. He paused for a second and continued.
"As for the last question, I've already said that it's a freebie question. Discussing academic issues is meant to speak freely, not to echo what others say. No matter what you say, as long as it's reasonable, I'll count it as a pass. "
Lu Zhou smiled awkwardly and asked, "Professor, will you take me to Switzerland?"
Professor Lu smiled and said, "Of course, I'll prepare the relevant documents for you. Go and get your visa done as soon as possible."
"Thank you, professor!"
"You're welcome, I promised you," said Professor Lu. He paused for a second and said, "Oh yeah, I want to ask you something."
Lu Zhou asked, "What?"
Professor Lu, "The LHCb China research group is still lacking a few interns. Are you interested?"
Lu Zhou paused for a second.
He was just thinking about how to ask Professor Lu to join the LHCb. He didn't expect happiness to come so suddenly …
…
LHCb was the abbreviation of the Bottom Quark Detector. It was an international research organization. Just like the BESlll International Cooperation Group, which was named after the abbreviation of the Beijing spectrometer, it was led by a country or an organization with the participation of researchers from many countries to complete a scientific research project together.
Currently, the focus of LHCb's research was to find the pentaquark particle "Pc +".
Based on a large number of experiments and calculations, even though they weren't sure what this particle was, they could infer from the constant mass spectrum analysis of J/σp that the particle's mass was around 4.5 GeV.
Unfortunately, the BESlll International Cooperation Group used the Shangjing Positron Collider. The energy zone was between 1 and 1, which was stuck at the lower limit of the "Pc +" mass threshold.
If they wanted to produce "Pc +", they would need at least 6 GeV of energy.
Therefore, unfortunately, this time, the Chinese researchers could only participate in the LHCb cooperation group's work as collaborators to find the exciting mysterious particle.
The China cooperation group was mainly led by Professor Gao from Shuimu University, and major universities in China also participated. Professor Lu Shenjian was also one of the people in charge of the China cooperation group. His work was mainly to measure the bottom baryon cross section.
Lu Zhou joined the China research group as an intern. Regardless of what role he played, he was at least participating in this historical work.
Lu Zhou was quite excited that he was about to witness history.
Of course, he was even more excited about the physics experience this experiment would bring him.
After all, this was a historical moment. It would definitely be more exciting than the mathematics conference in Princeton, right?
50,000?
100,000?
If only he could level up his physics to level 3.
At this moment, Shi Shang's voice interrupted his delusions.
"Zhou, what are you laughing at?"
Lu Zhou realized that he was laughing, so he was applying for a visa on his computer. He coughed and said, "Nothing, I just thought of something interesting."
Huang Guangming looked at the computer screen and said, "Passport? You're going abroad again? "
Lu Zhou nodded and said, "Yeah, around the beginning of May. I'm going to Switzerland with Professor Lu."
Liu Rui, who was doing questions, shouted, "666!"
He had almost formed a conditioned reflex toward Zhou's tricks.
Sometimes, he felt quite hopeless about his current self.
Huang Guangming was shocked, "F * ck me, going to Europe to show off? Another mathematics conference? "
Lu Zhou smiled and said, "It's not mathematics, it's physics. Also, what do you mean show off? I'm just an errand boy, and my main job is to listen to the boss. Even if I want to show off, I'm not the one doing it. "
Huang Guangming did not believe him.
Just then, Shi Shang suddenly said in an embarrassed tone, "Brother Lu, can I ask you for a favor?"
"What favor? Go ahead," said Lu Zhou.
Shi Shang smiled and said, "Can you help me bring something back from Switzerland?"
Lu Zhou, "What?"
Shi Shang thought for a bit and said, "Farman cosmetics … I think it's called this brand."
Huang Guangming was shocked again, "F * ck me, brother Fei, you use cosmetics?"
"F * ck off! It's for girls … Um, can you bring it back for me? I'll give you how much it costs. "
"Okay, I'll bring it for you when I see it," said Lu Zhou as he nodded.
This kind of small matter was something that he could do in passing. It couldn't be any easier.
Speaking of which, it was rare for him to go to Europe. Should he bring back some local specialties?
What does Switzerland have? Swiss army knife? I wonder if I can bring it on the plane …
Lu Zhou thought for a long time and could not think of anything to buy.
He thought about it and decided to bring some milk powder home. Xiao Tong was going to be a senior in high school and it would be good for her to prepare for the college entrance examination.
