Start with a college teacher

Chapter 59 The Foreign Monk

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

Students have 8-10 lessons a day, six days a week, with only one real break.

After such a long study time, it is difficult to achieve talent.

Those who thought of skipping classes at every turn were mostly liberal arts majors.

The students study hard, and the teachers are not easy to teach.

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, which mainly studies the basic laws of mechanical motion of objects.

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

However, there are advantages to being a professional 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 men and horses, two teams.

This set of people is actually Shen Guanglin alone.

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

Miss Li Rong has been very busy recently. She is already full-time studying, and she just wants to go to university.

To this end, Lao Li hired many teachers to help her with her homework.

High school students really don't look like that. If they can keep up with their grades, they should go to Jingcheng University. If they can't, they should go to the University of Political Science and Law.

This is a university that has just resumed in 78. The threshold is low and it 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, Citi, is coming to the school as a visiting scholar.

Who is Professor Charlie?

Whoever he is, the foreigner's name is either Charlie or Charles, and he's not very creative.

The full name of the University of California is the University of California, which is a very good and famous university in Citi.

It has a total of 10 campuses, each of which is excellent, and is a national public school, a model of Citi National Public University.

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

Of course, UCLA ranks second among the ten schools, and it is also a big name.

Its abbreviation is UCLA, and it is one of the most famous "sports universities" in Citiland.

Since 1920, UCLA students and alumni have participated in every Olympic Games, never absent, winning a total of 123 Olympic medals, including 233 gold medals.

A comparison of cattle.

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

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

Even, the NCAA basketball league is more concerned than the NBA basketball game.

The three schools, UNC, Duke and UCLA, are regulars in the NCAA championship race.

Abdul-Jabbar, Bill Walton, Baron Davis, Matt Barnes, Russell Westbrook and other basketball superstars are all from the UCLA school.

When it comes to UCLA, the first thing that comes to mind is its sports achievements. It is difficult to think that it will also have scientific research results.

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

To be honest, Shen Guanglin didn't want to see this Professor Charlie, not because he was timid, but a professor from a sports university. What research results could he have?
However, when people come to be visiting scholars, they still come with funds. The research funding alone is as high as 50 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 it was estimated that he had applied for it from a certain foundation.

There are many thieves in the foundations in Laomei, and it is said that this can avoid tax.

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

It's even possible to study how a piece of shit moves in outer space.

The old American foundation is generally generous when it allocates funds to scholars, but they also make some seemingly bizarre reasons.

Charlie's visit to China this time has to make people wonder if he has a certain political purpose.

The school has discussed it, but it is also a step by step.

Shen Guanglin did not want to see these Citi people who like to put on an arrogant posture but think they are humorous.

Although they may come here now with some goodwill.

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

Especially last year, after Taizong took action to teach the little brother in the south a lesson, the two sides have more foundation for "friendly cooperation".

From top to bottom, no matter official or private, everything is improving.

CCCP is our common enemy.

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

With authoritative education, advanced medical care, and perfect social system, Citi Country has compiled a seemingly prosperous and splendid article.

This kind of prosperity has deceived many Chinese people. When everyone wakes up, it is already after 2010.

And, even in science and academia, they'll put on a gesture that I'm the only one in the world.

Not to mention the arrogance and ignorance of ordinary people in Citigroup, that is, there is still no major improvement in 2020, almost the same as the ordinary people who are educated by Xiaoying.

Of course, the current Citizens did not come to China on purpose to show their superiority. They came here with pity and curiosity, just to see if technology in the third world has developed.

The historical feature of this era is that international relations are complex and pure, and so is academics.

Professor Charlie finally came. He was a lean-looking white man with a hairy face. He looked a bit like the Bear Grylls who claimed to be able to eat everything but lost to the preserved egg in the end.

As expected of a person from the "Sports University", Charlie can still maintain a good body shape in his 40s, and he probably has good physical fitness.

The speech was very successful.

The topic was about the theory of relativity, and the teachers and students at the meeting broke out with warm applause. The experts from the United States are really different, witty, humorous and powerful.

After the speech is over, it is time to get to know the talents of the Department of Physics.

When introducing Shen Guanglin, Professor Charlie also expressed his surprise at his youth: "A researcher who can publish a paper in Phys. Rev. B. at such a young age is not at the same level in Citi. common."

The accompanying department leaders did not introduce Shen Guanglin's background in studying abroad, but focused on his young and promising.

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

Charlie was not surprised.

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 at the undergraduate or graduate level.

"Come on boy, I wrote "Science" during my Ph.D., I hope you can too." This is an alternative encouragement. He doesn't think Shen Guanglin can really complete the challenge of "Science". After all, scholars in the third world , a country may not be able to produce one a year.

However, Shen Guanglin felt that he really should write a paper that reached the level of "Science". After all, he has achieved enough achievements: "Thank you, I will definitely work hard, but I don't know the selection of "Science" in this era. What is the standard."

"Science's primary focus is the publication of important original scientific research and research reviews, although Science also publishes science-related news, views on science and technology policy and matters of interest to scientists."

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

However, in Charlie's eyes, Shen Guanglin is a good person, at least his English is good, and he doesn't need a special translator to communicate with him.

"Shen, which course are you teaching?"

"Theoretical Mechanics."

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

Shen Guanglin also knew something about this.

After all, in later generations, quantum mechanics has made a relatively big breakthrough, and he has studied related content.

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

The history of quantum entanglement is also long. As early as 1935, during the Einstein period, Podolsky discussed the properties of quantum entanglement.

Later, after Schrödinger finished reading the EPR paper, he had a lot of thoughts, redefines the term "quantum entanglement", and studied and explored related concepts.

In 1964, John Bell presented 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, which is another breakthrough. .

In 1972, John Krause and Stadt Freeman were the first to test quantum entanglement.

Since then, quantum entanglement has become a hot research topic.

In the era of Shen Guanglin, quantum entanglement has finally developed by leaps and bounds, and some research results can already be based on applications.

"Are you also going to do experiments on quantum entanglement? This requires careful design, and it costs a lot of money."

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

Shen Guanglin shook his head, he didn't do these thankless things.

He just wants to study some purely theoretical breakthroughs and use his own money to do research. That's a saint.

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

By applying the mechanism of quantum entanglement to quantum information, many things that are usually infeasible can be achieved. I think it is enough to complete some theoretical defects of the theory. "

After listening to Shen Guanglin's words, Professor Charlie immediately became serious. What Shen Guanglin said was very interesting. This is indeed a good direction.

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

In the quantum key distribution mechanism, given two particles in quantum entanglement, it is assumed that both parties in the communication 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 blocked by both parties. Detect discovery. "

Shen Guanglin spoke out the common quantum key in later generations, which is the quantum entanglement theory for practical applications.

"Shen, you are truly a genius! Now, I solemnly invite you to visit California. It is you who should be the visiting scholar."
