High energy physics has always been a hot field of scientific research, and in addition to CERN, the world's large-scale and costly laboratories include Oak Ridge National Laboratory, Argonne National Laboratory, Stanford Linear Accelerator Center, Brookhaven National Laboratory, Fermi Laboratory, Helmholtz National Research Center in Germany, Motan Underground Laboratory in France, the famous Cavendish Laboratory, Lucia Research Center Kurchatov Institute, Neon National Institute of High Energy Physics, as well as the National Laboratory of Heavy Ion Accelerator and the Key Laboratory of Huaguo Academy of Sciences.

But these laboratories have their own pros and cons, the laboratories with the name of the country are closely related to national security, I am afraid that it will not be easy for a Chinese person to enter, even if Lu Qiujian changes his nationality and becomes a citizen of the United States to enter the laboratory, it is not easy to get in touch with the most core things, let alone cross the transparent ceiling and climb to the top level, so that the laboratory can be tested according to the plan designed by himself.

The same is true of Germany, France, Lucia, and Neon, who are much stricter in their protection against outsiders than in the United States, a country of immigrants, and the investment and research facilities in those laboratories may not necessarily be stronger than those in the United States.

The Cavendish Laboratory is the equivalent of the physics department of Cambridge, the founder is Maxwell, the founder of the famous electromagnetic field theory, and his successors include Joseph John Thomson and Rutherford, and since the birth of the Cavendish Laboratory in the 90 years, a total of 29 Nobel laureates have been trained, and the strength is simply jaw-dropping.

But after all, he is a university laboratory, and the funds and equipment are relatively limited, and if he only learns theoretical knowledge, it is not enough to participate in or even lead large-scale experiments! This does not match Lu Qiujian's needs.

As for Huaguo's laboratory, it is still in its infancy, and although the country's economy has been developing rapidly in recent years, there are many places to spend money. It is far from the level that the money is so big that he doesn't know how to use it, and the support for these two laboratories is not up to the level that Lu Qiujian wants for the time being.

So CERN is the best choice, the name of this institution may not be heard of by many people, but its research results are relevant to almost everyone.

The world's first web http://info.cern.ch, the first web server, The first web browser, World-Wide-Web, was born here, and in the '80s Tim Berners-Lee joined CERN's particle lab, where the lead researcher was the familiar Ding Zhaozhong, where he was tasked with developing software that would allow laboratories around the world to quickly share information over a computer network.

By '91, he had successfully completed this project and brought the world into the Internet age.

Of course, the Internet is nothing more than a by-product of CERN. It has also made good achievements in the field of high-energy physics, it is currently the world's largest particle physics laboratory, and was jointly established in 1954 by 12 countries including Germany, Britain, France, Italy, etc., and now has 21 member countries.

Located near Geneva, Switzerland, the laboratory employs more than 3,000 full-time employees. Around 6,500 scientists and engineers from 80 countries, representing more than 500 university institutions, conducted experiments at CERN. This is about half of the world's particle physics circles.

In addition to an unrivalled talent pool, it also has super scientific research equipment such as linear accelerators, proton synchrotrons, super proton synchrotrons, antiproton reducers, and most importantly, large hadron accelerators.

Excluding the construction of large facilities, CERN's annual budget is around CHF 1.1 billion. This is more than double the amount of research funding from the European Space Agency. In the world, it is only less than the National Aeronautics and Space Administration (NASA) of the United States.

There is no shortage of talents, equipment, and funds, and there is no such thing as the status restrictions of other national laboratories, at least for now, there is no more suitable place than here.

There are several ways to get into CERN. The first is to apply directly to work or study here, and the second is to take a roundabout route to a university or research institute that has a cooperative relationship with CERN, and then enter here.

Lu Qiujian chose the second path, because China is not a full member of CERN. Therefore, it is difficult for Chinese people to become regular employees here, and secondly, if you want to work here, the PhD degree is the starting price, and Lu Qiujian now only has a PhD in mathematics, which is not very compatible.

As for coming here to study. Although there are many Chinese people who come here for long-term or short-term learning through their own workplaces, the premise of this path is to have a cooperative work unit with CERN, which turns to the second path.

There are also a number of universities and institutions in China that cooperate here, but since they want to study, why not find a better mentor? Although there are such good people as Witten and Dyson in the United States, the distance from where to Geneva is too far, and it is far less convenient than that from Europe.

Considering the distance, the closeness of the relationship with CERN, the level of mentors and other factors, Lu Qiujian set the target for Germany and France, both of which are close to Geneva, and are also one of the core initiators of CERN, and also bear the lion's share of CERN's operating expenses, and their status in CERN is equivalent to that of permanent members in the United Nations.

As for the specific institutions and supervisors, Lu Qiujian is still screening, and his screening method is to first find the universities in these two countries that have cooperative relations with CERN and accept Chinese students, and then find out the part that has the closest relationship with CERN and the physics department ranks higher in the world university physics department rankings, and then enter the official webpage of these departments to collect relevant information about the tutors.

After that, make a list of these supervisors, find out their status in CERN, collect their papers for study, and then analyze their academic level, personal personality and other relevant information according to the papers, and finally score each condition, so as to screen out the most suitable supervisor for him to apply for his doctoral students.

As for whether the other party will admit him? Lu Qiujian has never been worried, with the letters of recommendation from Edward Witten and Freeman Dyson, coupled with his own strength, as long as the other party is not their sworn enemy, there are still universities in the world that he can't go to?

Of course, before that, he has to pass the language test of the target country, just like IELTS and TOEFL when going to an English-speaking country, whether it is French or German, Lu Qiujian is already ready, as long as he doesn't forget the time to register. (To be continued.) )

PS: The LHC hasn't been fixed in reality, but this is a parallel world, so it was completed ahead of schedule for plot reasons.
