Chapter 515 The first stop of the study tour

CERN, often referred to simply as CERN.

It is the largest particle physics laboratory in the world.

It is also the birthplace of the World Wide Web.

Some people also call it the land of annihilation of matter and matter.

As the name suggests, this is a concern for the high-energy collider owned by CERN.

CERN was established in 1954 and has a history of more than 50 years.

The main purpose is to provide particle accelerators and other infrastructure for high-energy physics research to conduct many international cooperation experiments.

As far as current information is concerned, CERN has employed about 80 full-time employees and has about 6500 scientists and engineers from [-] nationalities.

These scientists and engineers, representing more than 500 university institutions, conduct experiments at CERN.

In addition, there are countless interns and other personnel at CERN.

The number of these personnel accounts for more than half of the particle physics circles in the world.

This is one of the reasons why CERN is the largest particle physics laboratory in the world.

It not only has the largest collider in the world, but also has the largest number of researchers in particle physics in the world.

But if you really want to talk about the experiments held by CERN, the important achievements in particle physics, it is really not as good as the closed collider laboratory of SLAC.

In addition to the W and Z bosons discovered in 1983, the Higgs boson was discovered in 2012.

Although there is also Professor Schapak, who won the 1992 Nobel Prize in Physics for his invention of the multi-line proportional detector and the promotion of the particle detector.

But these are obviously not enough to compete with SLAC for honors.

Some people may say that the Higgs particle discovered by CERN can be smashed by one.

But this is obviously not scientifically proven, and it is an extreme word.

Of course, it is undeniable that CERN's current status is definitely NO.1 in the particle physics world.

No other particle physics laboratory comes close.

On June 6, Chen Zhou and Friedman started his planned "study tour".

The distance from MIT to CERN is not too far.

The straight-line distance alone is more than 6000 kilometers.

It can be said that Chen Zhou, Friedman and others arrived at the headquarters of CERN, which is located in the Meyhan area near Geneva, Switzerland, after a long journey.

Not counting the stopover time in London, the flight time by plane alone is more than 8 hours.

It was 6 o'clock in the afternoon when we arrived at Geneva Airport.

Together with Friedman, Chen Zhou looked for the pick-up sign, and soon found Cross and others who came to pick them up.

That's right, Cross was one step ahead and had already arrived at CERN before Chen Zhou, Friedman and others set off.

However, Chen Zhou didn't know whether Cross came to CERN to join or for other reasons.

Cross didn't say anything, and Chen Zhou didn't ask either.

"How is it? Did you feel comfortable on this flight?"

Cross, who drove the car out of the parking lot, joked with a smile.

He was the man who had suffered the pain of the long-distance flight.

Before SLAC closed the collider laboratory, he was in charge of the communication activities between SLAC collider laboratory and CERN.

At that time, it was really a week, all spent flying.

So, when he saw Chen Zhou's tired face today, Cross couldn't help but joked.

However, what Cross didn't expect was that before Chen Zhou returned to him, Friedman had already said quietly: "My old bone may not be able to fly a few times."

Immediately, Cross watched Friedman's expression through the rearview mirror nervously.

Speaking of it, the reason why Friedman set the first stop at CERN was also because of Cross's persuasion.

Only after seeing the largest collider laboratory in the world can they have enough confidence in the future to continue in-depth research in the field of collider experiments and even particle physics.

Therefore, when he found out that his "teacher" actually said such words, Cross couldn't help feeling ashamed and worried.

After all, Friedman was at that age, so it was really hard to bear such a long flight.

"Professor, you will be at the hotel soon, you can have a good rest at night."

Seeing that Friedman is in good condition, Cross relieved and changed his tone.

Friedman didn't speak, just nodded slightly.

Chen Zhou, who had a keen insight into all this, wanted to laugh, but he couldn't laugh, and felt a little uncomfortable.

Located at the southwest corner of Lake Geneva, Geneva is the second largest city in Switzerland and a world-renowned United Nations city.

People are most impressed by Geneva, probably the watch industry.

Patek Philippe, Vacheron Constantin, Rolex, IWC, Piaget, Chopard, etc., all come from Geneva.

Soon, Cross parked the car in front of the Starling Hotel in Geneva.

Chen Zhou and Friedman began to check in.

Later, the team members who followed Friedman to CERN for academic exchanges also arrived at the hotel one after another.

It is definitely impossible for Friedman's academic exchange to be just him and Chen Zhou.

Even if Friedman just wanted to take a look around, MIT would not agree.

Furthermore, if academic exchanges can be carried out at public expense, why is Friedman unwilling?
Of course, Chen Zhou simply took advantage of it.

In the hotel room, Chen Zhou and Yang Yiyi were playing the video.

"Yiyi, how is your project at LIGO going?"

Chen Zhou asked casually while sorting out his personal information.

All the materials from MIT have been mailed back to China by Chen Zhou.

Most of what he carries now is to provide "long-term" plans for future research directions.

Take mathematics as an example, the full-level upgrade task has come out.

He had to think about how to use 10 Goldbach's conjecture-level mathematical conjectures.

Will these 10 world-class problems have a corresponding connection?

As for tasks 2 and 3, Chen Zhou is not in a hurry, and can plan slowly during the study tour.

Yang Yiyi, who was on the opposite side of the video, lowered her head and ate a hamburger, muttering: "The progress is not bad, I guess there is still a week before the paper will be published."

Hearing the vague voice, Chen Zhou raised his head and took a look.

Yang Yiyi immediately stopped chewing, and smiled at Chen Zhou.

Seeing this, Chen Zhou said softly, "Why are you eating now? It's so late..."

Yang Yiyi resumed the chewing movement, and said with a smile: "I just finished the task in the laboratory, it's okay, it's not too late."

After a pause, Yang Yiyi said again: "I'm not like you. I don't have any sense of time when I'm busy. I remember three meals a day."

Hearing Yang Yiyi's words, Chen Zhou touched his nose, and did not refute, but said with concern: "Are you full if you only eat hamburgers?"

As soon as Chen Zhou finished speaking, Yang Yiyi hiccupped inappropriately.

The two were stunned for a moment, but then laughed at the same time.

Laughing without image at all.

"Yiyi, I have already arrived in Geneva, and I will go to CERN tomorrow."

Chen Zhou also stopped packing up the materials, and instead focused on watching Yang Yiyi in the video.

Speaking of which, since the two of them went to MIT, they have been together less and separated more.

Each of them is working hard for their own studies and goals.

For Yang Yiyi, having a boyfriend like Chen Zhou is quite stressful.

Although she herself is considered excellent, compared with Chen Zhou, she is still much worse.

Especially after coming to MIT.

Someone once made such a metaphor. The knowledge learned in elementary school, junior high school and high school is all basic knowledge, which can be regarded as a big circle.

When I arrived at the university, I started to get in touch with professional knowledge.

I started to refine part of the knowledge in this big circle and study it in depth.

When it comes to graduate students, it is in this part of the knowledge that it is further refined, studied and researched in more depth.

When I was a doctoral student, the research direction had already been determined, and the knowledge in this big circle had also been refined into a line, or a needle.

When a doctoral student has achieved something, completed his studies, and graduated, the needle pierced the circle of the big circle and began to go deeper.

In this process, every step of conversion is a leap forward, and the difficulty increases geometrically.

Therefore, at Yanda, Yang Yiyi could superficially follow in Chen Zhou's footsteps and graduate from Yanda together.

When she arrived at MIT, Yang Yiyi felt the increasing difficulty as the depth of research increased.

But Chen Zhou didn't, he was the same as before.

Whether it is the learning of knowledge, the degree of grasp of the subject research, or the moment of inspiration.

Chen Zhou was the same as before, as if he had never encountered the difficulty of geometric growth.

Just like now, Chen Zhou has finished his schooling career and started a new journey.

But he is still in LIGO, doing research projects with Professor Weiss.

This is actually where Yang Yiyi really felt that there was a big gap between her and Chen Zhou.

For the rest, what Yang Yiyi wondered was why Chen Zhou could be so good at both physics and mathematics?

This is not only the place where Yang Yiyi is puzzled, but also the place where everyone who knows Chen Zhou is puzzled.

Generally speaking, a person's energy is absolutely limited.

Even good mathematicians are good physicists.

Don’t talk about the future, just talk about the past, like Chen Zhou, he has almost never solved the Nobel Prize-level rubber ball problem and the Philippine Award-level brother-guessing problem within half a year.

However, if they can't figure it out, they can't figure it out. They can only think that the world of geniuses cannot be understood by mortals...

"Well, I'm counting the time, and you will arrive around this time." Yang Yiyi finished eating the hamburger in her hand and said softly, "Isn't it special that I stayed at the airport for several hours after flying for more than 8 hours?" tired?"

Chen Zhou nodded: "It's really tiring, but I'm okay, but Professor Friedman, I guess I'm not feeling well..."

Thinking of the episode between Cross and Friedman on the way from the airport to the hotel in the afternoon, Chen Zhou smiled and told Yang Yiyi.

After Yang Yiyi finished listening, she couldn't help but laugh too.

After a while, Yang Yiyi recalled the current rumors in the physics world, and couldn't help joking: "Happy, it seems that soon, there will be the first scientist in Huaguo to win the Nobel Prize in Physics~"

Hearing this, Chen Zhou said triumphantly: "That's right, you don't even look at who is opposite you, pay attention, you will be the wife of a Nobel Prize winner in physics in the future, you have to pay attention to what you say. ..."

Listening to Chen Zhou's words, Yang Yiyi immediately laughed.

In this way, before they knew it, the two chatted for a long time and talked a lot.

Fortunately, Yang Yiyi finished the task in the morning, so she was able to chat with Chen Zhou, who had a 6-hour time difference, for so long.

Otherwise, Yang Yiyi, who was in the afternoon, really wouldn't be free.

At 10:[-] p.m. local time in Geneva, the two hung up the video call.

Chen Zhou intends to rest early, so he can seriously visit CERN tomorrow.

On the other side, Yang Yiyi stared at the black screen of the phone, lost in thought.

After an unknown amount of time, she suddenly grinned, and Nan Nan said, "Although I can't keep up with his pace, I can't be pulled too far..."

Immediately, Yang Yiyi got up, tidied up the materials on the table, and went straight to the laboratory.

This night was the best night Chen Zhou had rested in so many days.

It may be because of being too tired the day before, or it may be because of the communication with Yang Yiyi.

Anyway, Chen Zhou who woke up early in the morning felt very energetic.

After the morning jog, Chen Zhou finished his breakfast quickly, and then began to urge Friedman and others to hurry to CERN.

Chen Zhou's enthusiasm not only surprised Friedman.

Even Cross diverted his thinking, wondering if this guy came here for CERN?
The more he thought about it, the more likely it seemed to Cross.

Think about it, Chen Zhou is famous for his mathematics, and he is an excellent mathematician.

But he turned down the invitation of Princeton, the world's mathematics center.

So what is he for?

What else could it be for?

It must be for physics with the same excellent research results!
In order to study glue balls more deeply, isn't CERN the best place for Chen Zhou after the SLAC collider experiment is shut down?
Thinking of this, Cross couldn't help looking at Chen Zhou through the rearview mirror.

He was thinking, if Chen Zhou really stayed at CERN, how would he choose?

CERN currently has a network of six accelerators and one decelerator in operation.

Each machine boosts the energy of the particles before they are experimented with in the beam or sent to a more powerful accelerator.

The purpose of Chen Zhou, Friedman and others' trip is to visit six accelerators and one reducer, and conduct in-depth exchanges on related experiments.

The order of their visits is also from low energy to high energy.

Today, take a look at two of the six accelerators, the linac.

These two linacs provide low-energy particles that are injected into the proton synchrotron.

One of the supplied low-energy particles is protons, and the other is heavy ions.

Not long after, Cross drove Chen Zhou and Friedman to the location of the CERN laboratory.

After getting off the car, Chen Zhou was not attracted by the inconspicuous buildings of the CERN laboratory at first sight.

Instead, he subconsciously looked at the mountains not far away.

The collider of CERN, the largest particle physics laboratory in the world, is buried under this mountain.

Chen Zhou couldn't help but think of a worry he had seen before.

It is about residents living on the border between Switzerland and France, who are often worried that they will suddenly disappear that day.

The reason is that the collider of CERN knocked out the "devil" that was blocked in other spaces.

Of course, this is just a joke.

For Chen Zhou, or for any particle physicist.

Even if it is a "devil", it will definitely be studied clearly...
