Today's universities are not as loose as those of later generations, and management is quite strict, especially for science students.

Students have 8-10 classes every day, six days a week, with only one real day off.

After such a long period of study, it is difficult to become a talented person.

Those who frequently think about skipping classes are mostly liberal arts majors.

The students study hard, and the teachers teach hard.

Shen Guanglin now has another burden. In addition to teaching English, he also has to teach theoretical mechanics.

Theoretical mechanics is a branch of mechanics that mainly studies the basic laws of mechanical motion of objects.

Theoretical mechanics is macroscopic mechanics, including statics, kinematics and dynamics. It is applicable to Newton's laws of motion and the law of universal gravitation. It is a part of classical mechanics, and its counterpart is quantum mechanics.

However, there are also benefits to being a professional course teacher.

That is, in addition to having his own "independent" office, Shen Guanglin also has his own "place" in the mechanics office.

This is the legendary set of people and two teams.

This team of people is actually Shen Guanglin's team.

Teaching two courses, Shen Guanglin and Li Li spent more time together.

My sister, Li Rong, has been very busy recently. She has been studying part-time and just wants to go to university.

For this reason, Lao Li hired many teachers to help her with her homework.

High school students really don't look good. If they can keep up with their grades, then go to Kyungseong University. If not, then go to University of Political Science and Law.

This is a university that was just reopened in 1978. It has a lower threshold and is more suitable for Li Rong.

In recent days, news has been circulating in the School of Physics that Professor Charlie from the University of California, Los Angeles, is coming to the school as a visiting scholar.

Who is Professor Charlie?

No matter who he is, foreigners are either called Charlie or Charles, which is very uncreative.

The full name of the University of California is the University of California. It is a very good and famous university in Citiland.

It has a total of 10 campuses, all of which are excellent, and it is a national public school, which can be regarded as a model of Citi's public universities.

Among them, the most famous among the 10 campuses is undoubtedly the University of California, Berkeley.

Of course, the Los Angeles campus ranks second among these ten schools, and it is also quite famous.

Its abbreviation is UCLA, which is one of the most famous "sports universities" in the country.

Since 1920, students and alumni of the University of California, Los Angeles have participated in every Olympic Games and have never been absent. They have won a total of 233 Olympic medals, including 123 gold medals.

A comparison of cattle.

Moreover, in the National Collegiate Athletic Association (NCAA) league, UCLA has won a total of 116 championships, ranking first in the United States in total number of championships.

They are very strong in basketball, football, baseball or other sports, especially in the cultivation of basketball talents.

In fact, the NCAA basketball league attracts more attention than the NBA basketball games.

Three schools, the University of North Carolina, Duke and UCLA, are regulars in the NCAA championship game.

Basketball superstars such as Abdul-Jabbar, Bill Walton, Baron Davis, Matt Barnes, and Russell Westbrook all came from the school UCLA.

When people mention UCLA, the first thing that comes to mind is its sports achievements. It is difficult to think of its scientific research achievements.

At least that's what Shen Guanglin had in mind.

To be honest, Shen Guanglin was not willing to meet Professor Charlie. It was not because he was timid, but because he was a professor from a sports university. What research results could he produce?

However, when people come to be visiting scholars, they still come with funds. The research funds alone are as high as 500,000 US dollars. This is a resource advantage that domestic researchers do not have.

Of course Shen Guanglin knew that Charlie's money was definitely not his own, and he probably applied for it from a foundation.

There are many foundations in the United States, and it is said that they can avoid taxes.

Each foundation has its own unique purpose and wants to study anything. It is estimated that the purpose of Charlie's funders is nothing more than political or other.

It is even possible to study the movement of a piece of shit in outer space.

American foundations are generally very generous when allocating funds to scholars, but they will also come up with some seemingly bizarre reasons.

Charlie's visit to China this time has people wondering whether he has a certain political purpose.

The school has had discussions, but they are just taking it one step at a time.

Shen Guanglin did not want to see these Citizen people who liked to put on arrogant postures but thought they were humorous.

Although they may have come here with some good intentions.

After all, it is still 1980, and Sino-US relations are still in an unprecedented "honeymoon period."

Especially last year, after Taizong taught the little brother in the south a lesson, the two sides had a better foundation for "friendly cooperation."

From top to bottom, whether official or private, everything is improving.

CCCP is everyone’s common enemy.

In fact, the exchanges between China and the United States are not reciprocal.

Citigroup relied on its authoritative education, advanced medical care, and perfect social system to create a seemingly prosperous and splendid article.

This kind of prosperity has deceived many Chinese people, and by the time everyone woke up, it was already after 2010.

Moreover, even in science and academia, they will act like I am the only one in the world.

Not to mention the arrogance and ignorance of ordinary people in Citiland. Even in 2020, there has still not been a big improvement. They are almost the same as ordinary people under the education of Xiaoying.

Of course, today's Citizen people do not come to China intentionally to show off their superiority. They come with pity and curiosity, just to see whether the technology in the third world has developed.

The historical characteristic of this era is that international relations are complex yet pure, and the same is true for academics.

Professor Charlie finally came. He was a rough-faced Caucasian who looked somewhat capable. He looked a bit like Bear Grylls, who claimed to be able to eat anything, but lost to preserved eggs in the end.

As expected of someone who graduated from the "Sports University", Charlie can still maintain a good figure in his forties and is probably in good physical condition.

The speech went very successfully.

The topic was about the theory of relativity, and the teachers and students present burst into warm applause. The experts from the United States were indeed different, humorous and powerful.

After the speech, it was time to get to know the talented people in the physics department.

When introducing Shen Guanglin, Professor Charlie also expressed surprise at his youth: “A researcher who can publish a paper in Phys. Rev. It’s also rare.”

The accompanying department leaders did not introduce Shen Guanglin’s study abroad background, but focused on his youth and promise.

"Mr. Shen is not only a teacher, he is also the dean's doctoral student."

Charlie said he wasn't surprised anymore.

As a doctoral student, it is not surprising to be able to publish some high-end papers. Some people even get the opportunity to publish in "Science" or "Nature" during their undergraduate or graduate studies.

"Come on, boy, I wrote "Science" while studying for a Ph.D., I hope you can too." This was a different kind of encouragement. He didn't think Shen Guanglin could really complete the challenge of "Science". After all, the Third World Scholars, a country may not be able to produce one article in a year.

Shen Guanglin felt that he should really write a paper that reached the level of "Science". After all, he had achieved enough achievements: "Thank you, I will definitely work hard, but I don't know what the level of "Science" is in this era. What are the criteria for selecting manuscripts?”

"Science's main focus is to publish important original scientific research and research reviews, but of course, Science also publishes science-related news, opinions on science and technology policy and matters of interest to scientists."

Charlie spoke the official language, and Shen Guanglin said he knew what science was and what the general rules of "Nature" were.

However, in Charlie's eyes, Shen Guanglin is still a good person. At least he speaks good English, and you don't need a special interpreter to communicate with him.

"Shen, which course do you teach?"

"Theoretical Mechanics."

"It is difficult to make breakthroughs in theoretical mechanics. The most profound one is quantum mechanics." Professor Charlie is very proud of his research direction.

Shen Guanglin also knows something about this.

After all, in later generations, there were relatively big breakthroughs in quantum mechanics, and he had studied relevant content.

"I have also dabbled in quantum mechanics, and the title of the next paper I am preparing is quantum entanglement." Shen Guanglin stated his "research" direction very directly.

Quantum entanglement has a long history. As early as 1935, during Einstein's time, Podolsky discussed the characteristics of quantum entanglement.

Later, after Schrödinger finished reading the EPR paper, he had many thoughts and feelings. He redefined the term "quantum entanglement" and researched and explored related concepts.

In 1964, John Bell proposed a paper showing that if the spins of two particles are measured along different axes, the statistical correlation results obtained by quantum mechanics are much stronger than the local hidden variable theory. This was another breakthrough. .

In 1972, John Krauser and Stat Freeman first completed the test experiment of quantum entanglement.

Since then, quantum entanglement has become a popular research subject.

In Shen Guanglin's era, quantum entanglement finally made great progress, and some research results could already be applied.

"Do you also want to do a quantum entanglement experiment? This requires careful design and costs a lot of money."

Professor Charlie is indeed active at the forefront of science. He recognizes the theory proposed by John Bell, but it is difficult to perfectly verify it.

Shen Guanglin shook his head, he would not do such thankless things.

He just wants to study some purely theoretical breakthroughs and uses his own money to conduct research. That is a saint.

"Professor Charlie, quantum entanglement is a physical resource, like time, energy, momentum, etc., that can be extracted and converted.

By applying the mechanism of quantum entanglement to quantum information science, many things that are usually infeasible can be achieved. I think it only needs to solve some theoretical flaws of the theory."

After listening to Shen Guanglin's words in class, Professor Charlie immediately became serious. He found what Shen Guanglin said very interesting and this was indeed a good direction.

Shen Guanglin went on to say: "For example, the distribution of quantum keys can enable both communicating parties to share a random and secure key to encrypt and decrypt information, thus ensuring communication security.

In the quantum key distribution mechanism, given two particles in quantum entanglement, assuming that the communicating parties each receive one of the particles, since measuring any one of the particles will destroy the quantum entanglement of the pair of particles, any eavesdropping action will be detected by both communicating parties. Detection and discovery.”

Shen Guanglin talked about the quantum key that is common in later generations, which is the quantum entanglement theory for practical applications.
