"I'm very happy to see you all here today. You should have seen my resume in the introduction of the professor in this course. But before the formal class, I still hope to introduce myself to you as usual. My My full name is Hope W. King. I don’t know how other foreigners introduce themselves, but I like to tell you about my family name. In fact, due to cultural differences, my family name is similar to the one everyone knows as Martin. Luther King had nothing to do with it.”

"Okay, the above is a joke. But let's not joke next. When Professor Ning asked me to tell you about the foundation of modern physics in space and time, I struggled deep in my heart. Because after reading the lesson plan, I was very skeptical. Whether studying this course at the undergraduate level is suspected of being counterproductive, I can say without exaggeration that so far no university in the world will offer such a course at the undergraduate level.”

"But Professor Ning told me that the students in my class, well, that is, you, are the best students in the world. Most of you have participated in the International Physics Olympiad and won awards. Many of you have The ranking is still very high, and many people have even studied college courses in high school. All I have to do is pass on the knowledge to you, and you don’t need to worry about whether you can understand it, because you will definitely understand it.”

"I chose to believe Professor Ning and took over this task. Because he never missed it. About a year ago, physicists all over the world, including me, thought he was wrong. But the subsequent laboratory data showed that Prove that Professor Ning is right! This is why I am standing in this class today. This is my life creed, do the right things with the right people."

"But even so, I still want to remind everyone that in my teaching career of nearly ten years, the courseware for this course is the most difficult to complete. And everyone knows that this course is rarely arranged in two parts. It takes two academic years to complete it, with a total of 12 credits, which can prove its importance and difficulty. Next, I will give a brief introduction to this course."

“The first half of this course requires us to briefly sort out the various hypotheses that constitute space-time, as well as the basic knowledge of the relationship between space-time and mechanics. It includes many theoretical studies, such as the thermodynamics that gravity comes from the bottom of space-time. relationship, the possibility of entangled dynamics of space-time itself; explore the possibility that the entangled structure of boundary field theory leads to the internal space-time structure through the holographic entanglement entropy formula; the possible relationship between the entangled structure of boundary field theory and Einstein's equation, etc...."

"The second half is a discussion of time and space in Ning's basic theory proposed by Professor Ning based on previous theories. Believe me, children, if you don't have a deep understanding of the first half, you want to understand the second half Some of them are nothing more than wishful thinking, such as the view and argumentation process that continuous space-time is supported by a discrete network structure, and even theoretically denies that gravity is a fundamental force."

"It's very unbelievable, right? So this is a subject that if you fall behind from the beginning, you may not be able to catch up. What's even more frightening is that Professor Ning told me that the elimination rate of your class in two years may reach 50%. ! And the passing rate of this course is one of the important criteria for whether you can continue to stay in this class."

"I don't want any of my classmates to be eliminated. From the perspective of a substitute professor, I hope that each of you can keep up with my course. This requires everyone to first establish some of the most basic and counter-intuitive physical thinking logic. For example, The unification of micro and macro may cause confusion in your thinking and logic. For example, everyone should be aware of the phenomenon of quantum entanglement, but this phenomenon obviously violates the principle of local reality. At the same time, the quantum superposition state we often talk about also It is inconsistent with the principle of local reality.”

"In the past physics foundation, I would habitually tell you that you can simply associate the superposition state with Fermi Dirac statistics, the entangled state with Bose-Einstein statistics, and the classical state with Maxwell-Boltzmann statistics. Statistics. Especially the classical state. When we describe the N-slit interference experiment of electrons, we can directly use it to describe the total probability of observing electrons. In particular, it seems to naturally correspond to Bourne's law, and does not even require a wave function. derivation process.”

"But after Ning's theory has been proven to a limited extent, these tools have been replaced, and we have more effective research tools. This is the significance of this course. You are the luckiest, because this course will allow you to recognize Clear the future development trajectory of physics, allowing you to be at the forefront of the latest physics theories at the undergraduate level. I simply can’t imagine what level you will reach when you complete your undergraduate studies and officially become graduate students. .”

"The last digression, I very much hope that you can choose me as your tutor to continue your studies after graduation. If you can get used to my teaching mode. In addition, given the difficulty of this course, although I will not stay in school for a long time here, but your director still arranged an office for me, which is in room 411 of the south building of your physics building. I will stay there every Saturday afternoon from one to six o'clock. If you have any objections to this course? If you know anything about it, you can go there and find me during this time, and I will answer your questions in detail."

"Now let's officially start the first lesson, the concept of space and time in the history of physics. When it comes to this issue, we need to start with an extremely special force. It was the first to be discovered and has not been fully understood by scientists until now. Force - gravity..."

…

"bell……"

When the bell rang, the children under the podium spontaneously began to applaud.

This somewhat surprised Hope King. After all, he was not giving a lecture today, but standing on the podium as a teacher. If nothing else happens, he will still have two years to stand on this podium and impart the knowledge from the latest textbooks to these students.

But after a moment of astonishment, he reacted, smiled and waved to the audience, and then put away the lesson plans on the desk. I'm still in a good mood, at least on this point I'd rather not lie. These kids from Huaxia are really excellent students.

This even made him feel slightly regretful. Maybe he could have accepted a few Chinese students in the past...

However, the students who flocked to the desk made him calm down. Although it was the first class, there was still a lot of information. The students asked questions after class time. Although he was not obligated to give simple answers to everyone, it was a lot for him as a newbie. It doesn’t seem like it’s okay to give something.

So I started some more detailed explanations...

"...Oh, this question is more advanced. First we have to look at this formula, Sent=min(A)/4Gn. Did you find that the minimal surface is homotopic with the area on the boundary where the entanglement entropy is to be calculated? . Although this formula has not been completely proven..."

What makes Hope King feel quite happy is that the children who came to ask questions not only did not understand some parts of the class, but also extended more ideas. I hope he can solve their doubts...

This also gave him a new understanding of the excellence of these Chinese children.

They drew inferences from one example, spoke seriously, and listened carefully. No one noticed that there was someone sitting in the last row of the classroom wearing a mask, and they didn't even move their buttocks.

In this way, he was surrounded on the podium for nearly twenty minutes, until the applause of "papapapa" started. Well, someone kept applauding in the classroom.

Hope King raised his head in astonishment, and the students surrounding him also turned their heads and looked over, and saw someone in the last row of the classroom standing up and taking off his mask.

"Professor Ning?"

"Hello, Professor Ning!"

"Well, hello everyone, it's a good thing to seek knowledge, but it's a bit too much for you to block the teacher there for half an hour after class and not let him leave. If you have any questions, think about it yourself first. I really can't figure it out. Every Saturday The time for professors to answer questions is the same as that of Ningban. In the future, the professors of each of your courses will spend half a day to answer questions for you. In the same way, if you have any questions after class, you can just block the professor for twenty minutes. When the time is up, be more conscious. Ah, it’s time for lunch, aren’t you hungry?”

Ning Wei criticized it naturally.

Of course, the tone was not serious at all, at least there was a smile on his face, but the students in the class were very obedient and did not surround Professor Hope King. They politely said goodbye to the two professors and left the classroom.

Hope King was finally able to pick up the lesson plan that he had packed up and walked to Ning Wei.

"Professor Ning, you are too young. You are no different from those students sitting in class. I didn't even recognize you."

"Haha, that's because I'm wearing a mask." Ning Wei replied cheerfully, and then asked: "How is it? Am I right? These children are all excellent."

"Yes, they are all very, very good children, even beyond what you describe as excellent. I think the next teaching career will be very enjoyable." Hope King shrugged.

Two words, "very" and "nice", were used in one sentence. After saying this, the newly appointed professor immediately added: "But I still maintain my previous idea. I am only responsible for the undergraduate teaching tasks here for four years. I can take care of some graduate students after this year, but I won’t continue to teach undergraduates. There’s no way, I’m no longer young, and I still hope to focus more on scientific research.”

"Haha, don't worry, Hope, we Chinese people respect contracts the most. Just like we say that science knows no borders, we will share the latest results with the world. Okay, let's not talk about this for now. I want to celebrate you at noon today. The first class at Yanbei University was a complete success. I’ll treat you to dinner. Believe me, Hope, you will fall in love with Huaxia. I also called a friend who is your compatriot. I believe you will also become friends. of."

Ning Wei happily patted Hope King on the shoulder and said.

As one of the first batch of international professors willing to teach undergraduate students, Ning Wei felt that he should be given the highest courtesy - a treat to eat.

For the School of Physics of Yanbei University, this is probably the beginning of the success of the class.

A complete win-win!

The news about the proof of super-light transmission of information in the laboratory and the fact that there is no upper limit to the speed of information transmission has been hot on the Internet for a while and then disappeared. After all, it is still too far away for ordinary people to start thinking about interstellar exploration.

The theoretical breakthrough may lead to a gap of several years or even decades in reality. Therefore, except for a few technology enthusiasts who are still collecting this information in various aspects, the focus of the vast majority of netizens is still on the trivial matters of daily life. .

Idol has released a new song, the price of pork is about to increase, Huawei and Apple have released new mobile phones, the Chinese men's football team has lost again, a new hot pot restaurant has opened on the street and the taste is amazing...these are the real things that ordinary people want Life.

As for super-light information transmission, it sounds like a very powerful thing, but it is not possible to make 5G faster for the time being. Naturally, it will be done with just a little excitement.

Of course, the impact in academia remains profound.

This time, it is not just the American education community that has begun to realize that something is wrong. CERN, which has always had its eyes on the top, has also realized the recent loss of USER. It is easy to do so. The research efficiency of many topics has slowed down significantly. Apply for new topics. There are fewer people, and there are fewer papers.

This was unimaginable before.

As the location of the world's only world collider, only here can we obtain first-hand data and explore the nature of the world through high-intensity particle collisions. CERN is worthy of its reputation in the world, having sent out many Nobel Prize winners, and is responsible for 90% of the high-quality paper output in the high-energy physics community. It is no exaggeration to say that CERN never thought that one day they would be short of scientific researchers...

As long as the Large Hadron Collider remains the world leader, this situation is almost impossible to happen.

Although China is also building a collider, the principles of the two are slightly different, and hasn't it been officially launched yet?

However, before China's collider was officially started, it encountered the problem of manpower loss...

In the past, CERN actually did not need to bear too many resources for these physicists. After all, many scholars came on their own initiative, with funds prepared by the school or themselves. The current situation is that in the past, application projects had to be queued for review, but now they no longer have to. We have to wait in long queues, and even some projects that were impossible to pass before can now be passed as appropriate...

The problem is serious, and it has forced the management to consider a new issue - how to maintain academic output and ensure CERN's status.

The cost of maintaining the Large Hadron Collider is very high, especially the one that has just undergone maintenance and upgrades. If the efficiency decreases, the demand decreases, and the economic depression of member states and other factors are combined, it can be seen that the future will not be the same. So happy. Although it has not yet reached this level of urgency, the trend is already obvious...
