From all-round academic master to chief scientist

West of Geneva, Switzerland, on the border with France.

This is where the European Organization for Nuclear Research, the Large Hadron Collider LHC, is located.

The Large Hadron Collider is called ‘large’, and it is indeed very large.

Before 2010, the world's largest particle accelerator was the Tevatron accelerator in the United States, which belonged to Fermilab.

And its circumference is 6.28 kilometers.

After 2010, the LHC was successfully constructed. Its ultra-long orbit with a circumference of 27 kilometers allowed it to directly surpass the Tevatron accelerator and become the largest collider.

A circle of 27 kilometers is undoubtedly quite huge. It covers an area of ​​more than fifty square kilometers, making it one of the largest buildings in the world. Perhaps only the Great Wall can crush it in length. .

At this moment, inside the LHC, a group of people were visiting this huge building full of technology, and one of the leaders was Lin Xiao.

I came to the LHC because of his previous initiative to recalculate the mass of the W boson.

Under his initiative, the project to recalculate the mass of the W boson was established, relying on CERN, which provides funding and space. Of course, this is also the responsibility of CERN, which is to provide various conveniences for the research of high-energy physics. , this is the meaning of its existence, and it goes without saying how important Lin Xiao’s project is. Of course, CERN must fully support it.

As for the general person in charge of this project, it is naturally Lin Xiao, including him who has now become an important partner of CERN.

For such a project, many high-energy physicists in Europe naturally do not want to miss such an important thing and have joined in. Now the entire project has more than 500 people, excluding CERN graduate students and interns. In addition to researchers, there are probably more than 100 first-class high energy physicists.

This is obviously a luxurious lineup, and of course, their project deserves so many people to join.

Remeasurement of the mass of the W boson has always been an important issue in high-energy physics research.

This is because the W boson decays very fast, about one trillionth of a second.

In such a short time, it is obviously very difficult to directly measure its mass. It is even said that they cannot directly observe the W boson at all, and can only calculate its mass through the products after the decay of the W boson. , that is, by measuring the position and momentum of these particles, calculations are realized.

But no matter what, there are quite a lot of difficulties, which involve factors such as their calculation methods, software algorithms, and data collection and processing methods. Of course, it is also related to the collider, because if the collider If the collision energy is larger, more W bosons can be produced in one collision, and more W bosons means more data, which will benefit their subsequent calculation accuracy.

But obviously, their LHC is currently unusable and is still being upgraded and maintained, so they can only use past data for calculations, which means they need to modify calculation methods, software algorithms, data collection and processing methods, etc. .

There is no doubt that this has a lot to do with mathematics.

As for Lin Xiao, who can be said to be one of the best mathematicians in contemporary times, the physicists who came to help Lin Xiao still believe in him. He is good in physics and mathematics, and maybe he can really make it happen. Did they accurately measure the mass of the W boson?

So everyone has expectations for this.

Of course, their project was not in a hurry to start. For Lin Xiao, it was his first time to come to the LHC, so he came to see what it looked like out of curiosity.

The LHC is located 100 meters underground. It is so huge inside that it looks like an underground shelter that accommodates all humans in a doomsday movie.

Of course, the scene inside is not as messy as the shelter. The lights inside are bright and there is a wide pipe in the middle. There are staff standing next to it to check the situation, and there are more pipes nearby.

The wide pipe in the middle is the core of the LHC. Inside is a long and narrow pipe, which is also covered with niobium-titanium alloy wires. Niobium-titanium alloy is currently the most economical superconductor. It only requires the temperature of liquid helium to make It reaches a superconducting state.

For particle accelerators, it is very common to use superconductors to enhance their magnetic field strength. Of course, this also means huge costs. After all, reducing all superconductors more than 20 kilometers long to the superconducting state consumes The energy is a huge expense, more than 400 tons of liquid nitrogen. After each collision, it takes more than four months to wait for it to return to normal temperature before they can release it. .

Looking at these things, Lin Xiao couldn't help but sigh in his heart, this kind of thing is probably a modern version of a miracle, right?

Its appearance, full of a sense of technology, is probably why so many physicists are willing to stay here.

"Lin, how do you feel?"

CERN President Fabiola Gianotti asked with a smile.

Lin Xiao smiled and said: "It's very impressive."

"If you are willing, we are also willing to invite you to become our lifelong chief scientist. In the past, we did not set up this position." Gianotti said: "You will be able to enjoy many things by then, and we are willing to provide you with We provide an annual salary of five million euros and a research funding of ten million euros. If you have any important projects, we can also try our best to meet your requirements."

"do you have any requests?"

"We just need you to stay with us. As you know, we are planning to build a larger accelerator, which is the [Future Circular Collider]. It is also led by CERN and has the highest total collision energy value. It will be as high as 16.7 GJ, 30 times that of the LHC. When it is built, this huge, energy-filled super collider will be under your control at that time."

"Stay here? No need to apply for citizenship or anything?" Lin Xiao said jokingly.

"We will not force you, but of course we in Europe will welcome it if you want it."

Lin Xiao smiled and said: "The future circular collider is too far away. I'm afraid I will have to wait until I am in my fifties. The CEPC planned to be built by China is closer to me."

"What's more, I am a Chinese, and I still hope to return to my hometown."

"Don't you think about it more?" Fabiola Gianotti said sincerely, "I heard that many people are slandering you on the Internet in China recently. If they don't cherish you, why go back? "

Lin Xiao was silent for a moment. There were indeed many voices slandering him on the domestic Internet. These voices seemed to appear suddenly. They were just saying that he stayed abroad and would not return to the country, insulting him, and even worse, She also directly sent private messages to scold him.

But after a brief analysis, he easily guessed that it was organized by other people, which made him a little confused. He had not done anything now, he just published two papers and made a name for himself. Could it be that Does it infringe on other people's interests?

But no matter what, the facts have been established, and it is impossible for him not to go back. At least, there are still quite a lot of people who support him, not to mention that people can use such despicable methods, maybe they want him not to return to the country?

Then he would go back to China and make those guys uncomfortable.

Later, he said: "Society is very complicated, and China is the same. You don't need to worry about this kind of thing."

"Okay." Gianotti had to say: "You Chinese people are the people I can't understand the most. You always want to go back to your hometown. It's hard for us to understand such behavior. Where do we get it from here?" Go wherever the conditions are good.”

Lin Xiao shook his head and said: "Aren't there also many Chinese people staying abroad? It's just that there are still more people who are willing to go back."

"But it's different from what we think. Is this probably a cultural difference? Like Yang."

Lin Xiao smiled and said, "Maybe."

It is indeed cultural differences that can better illustrate this point.

No matter what, there are still relatively many people who are willing to return to China. At least the return rate is higher than that of other countries. Just like if European talents go to the United States, the possibility of eventually staying in the United States is obviously greater. .

"Okay, I've finished reading it. Now go back. Our project will officially start tomorrow."

Lin Xiao said at this time.

"OK."

Gianotti nodded.

Then, they left here and returned to the research center on the ground, and then prepared to carry out their projects at the research center tomorrow.

…

Hua Guo Shangjing, in a small rental house.

A man is browsing the Internet on his computer.

If Lin Xiao were here, he would definitely be able to recognize this man as Kong Huaan.

Now Kong Huaan is the most outstanding student at the School of Computer Science at Beijing University. He has also opened a company. With his computer skills, he accepts various outsourcing. Now he is famous in the industry, and any order is worth six figures. Remuneration, major companies are offering millions and equity incentives to hire him.

Now, his family no longer stops him, but are proud of his achievements.

In addition to this, he is secretly the boss of the [Shadow] organization that has recently become famous in the hacker world. His codename is [Terror], and he is respected by others in the hacker world.

It's just that he, who was already a complete winner in life, at this moment, showed anger on his face. This anger naturally came from the angry and even disgusting words on the screen.

"Why are you talking so much? I don't know why you are praising that kind of person. He is famous abroad. Do you think he will come back?" It's so funny"

"Return to Lin God, if I don't return to my country, I will only call Lin ÷"

"Stop bragging, stop bragging, what about Einstein and Newton? Are you bragging like this about people giving you money?" 』

"Do you want to be like that old guy named Yang, who contributed to foreign countries when you were young and then returned to China to be Mr. Yang when you are old?" 』

…

Looking at these comments, Kong Huaan was filled with anger.

Although he didn't have much contact with Lin Xiao, only occasionally, he always regarded Lin Xiao as his benefactor and his only friend in his heart.

At the beginning, he asked Lin Xiao to download a software to prevent hacker intrusions. Over this long time, he has indeed helped Lin Xiao intercept several intrusions or perform data monitoring. For scientists like Lin Xiao, of course, his various data It will attract the attention of some people. For example, the software he uses is very good at collecting various data about him. There are also some foreign forces that have launched intrusions into his computer.

All of these were blocked by Kong Huaan's original software. Even if it couldn't be blocked, he would take action himself.

Some time ago, he heard that Lin Xiao was famous in the physics community, and he was also happy for Lin Xiao.

However, at this moment, seeing the deliberate slander against Lin Xiao on the Internet, he was very angry.

Then, he logged into the web page and entered a certain website, which was exactly the website he gave Lin Xiao.

Later, he made a post in it.
