God's Crown

"No." An Yan turned her head and looked at the person who was talking to him, "I am from Yucheng, but I may not be able to come back for several years."

"Study outside?"

"Yes."

"What's the big deal, study hard, and when you've learned it well, can't you just come back and build your hometown?" The man said with a smile, "Isn't it just watching you college students in the future?"

"However, there are still a small number of people returning to Yucheng. After all, there are indeed many places in Yucheng that are not comparable to other big cities."

"I look at you, are you going to study in the capital? What school are you in?"

"No, I'm just going to change planes. I'm studying in the United States." An Yan showed a wry smile, "If I was studying in the capital, I should... be able to go home. But studying abroad, there are not so many people. time to go home.”

"Yes, studying abroad." Sighing, the man shook his head and said, "It's also very good. I heard that many schools abroad are much better than ours in Huaguo. You learned knowledge there. , It is also good to return to China and build the motherland."

"It's just that I can't go back to China for several years. I think it's a bit too annoying." An Yan sighed, "But you are right, there are indeed some areas in foreign countries that are more advanced than domestic ones. We We should learn from foreign advanced places and find out our own shortcomings."

"Instead of stubbornly thinking that domestic is better than foreign."

"Admit the gap. It is the gap that can truly surpass your opponent." The man smiled and said, "So I think that as a college student who can study abroad, your grades should be very good. Learn well After graduation, I think it’s pretty good to bring foreign knowledge back to China.”

"Thank you." An Yan smiled, and soon the plane took off.An Yan slept on the seat. After arriving in the capital, he didn't leave the airport, but stayed in the airport. After a while, he had to get on the plane to California, and there was no need for him to leave the airport.

After sitting for a while, he boarded the plane.

When I came to California, it was afternoon.An Yan straightened out her thoughts and left the airport.Go directly to Stanford University, which is adjacent to Silicon Valley, a world-renowned high-tech park, and together with the University of California, constitutes the academic center of the western United States.Naturally, it is a school with a very strong academic atmosphere. When I came to Stanford University.

The sun was shining loosely on the earth, and crowds of twos and threes shuttled around him.An Yan showed a smile, he is now looking for Professor Hudson's office.

I received an email from Professor Hudson before, telling him that he can go directly to the office to find him when he comes to Stanford University.

After arriving at Stanford University, An Yan didn't even go back to her dormitory, but went directly to Professor Hudson's office to look for Professor Hudson.

However, Professor Hudson's office is not so easy to find.After An Yan walked around Stanford University, she still couldn't find Professor Hudson's office.He was a little puzzled, where would the professor be?If he just searched aimlessly like this, he didn't know how long it would take him to find Professor Hudson's office.So he looked at the pedestrians walking beside him.

Pulling the suitcase forward, he said to passers-by, "Hi, may I ask where Professor Hudson's office is? Professor Hudson of high energy physics."

The pedestrian was a typical European and American white man. He looked at An Yan for a while, then stretched out his hand and said, "Did you see that little house in front of you?"

An Yan looked in the direction the pedestrian was pointing at, and sure enough, not far ahead, he saw a small house with white tiles.The man said gently, "Professor Hudson usually works there. Are you looking for Professor Hudson?"

"Yes." An Yan nodded and said, "I'm here to report to Professor Hudson."

"Professor Hudson's student?" The passerby froze for a moment, looking up and down An Yan strangely.The man with an Asian face in front of him turned out to be a student of Professor Hudson, and his time at Stanford University was not too short.Unexpectedly, Professor Hudson's student would be an Asian.

Of course, Professor Hudson himself did not have any racial discrimination, but he was surprised.Professor Hudson has not accepted students for several years, but he did not expect to admit a student with an Asian face this time.

Professor Hudson does not accept students, not because he is too arrogant, or because he looks down on students from Stanford University.It's just that they are old, and in the past few years, no new students have been accepted at all.Although Professor Hudson did not win the Nobel Prize in high-energy physics, he has also won many other international awards.It can be regarded as one of the professors with a very high academic reputation at Stanford University.

"That's right." An Yan glanced at the person who was looking at him, he was a little confused, why this person was looking at him like that, is there anything strange about him?

No way, there seems to be nothing wrong with him, maybe something is wrong with him.

After thinking about it, An Yan was a little lost.But this pedestrian looked like a very gentle person, An Yan blinked his eyes and said, "Excuse me, is there any problem with me saying that?"

"No." Pedestrian shook his head and said, "I'm just a little surprised that Professor Hudson accepted students again." Pedestrian smiled and said, "I've been studying at Stanford University for several years, and this is the first time I've heard of Ha Professor Hudson accepts students. Although Professor Hudson did not win the Nobel Prize, Professor Hudson is undoubtedly one of the best high-energy physics professors at Stanford."

"You can become Professor Hudson's student, which is enough to show that you are very good." When he said this, the passer-by smiled at An Yan and said, "It's a pity that I am from the Department of Chemistry, otherwise Professor Hudson would accept you again." Students, I think I can try it too."

An Yan didn't speak, but just smiled.

"By the way." The passer-by glanced at An Yan and said, "May I ask what your name is? If you can become Professor Hudson's student, I believe you will not be an unknown person."

"My name is An Yan, from China." An Yan stretched out her hand and said, "Hello, what is your name?"

"Oh, so it's you." The passerby looked suddenly enlightened, "I said why Professor Hudson accepts students, so it's you."

"Eh..." An Yan was a little confused about what this man meant, but seeing his shocked expression, it seemed as if he really knew himself.

"Excuse me, have we met before?" An Yan asked with a cautious expression, as if he was afraid that something would offend the person in front of him.

"No." The man shook his head and said, "We haven't met, but I know you. Ann, you are a big celebrity at Stanford."

"Me?" An Yan pointed to himself, and said in disbelief, "No way, I've been to Stanford University three times, the first time was with a professor from the University of Zurich, and the second time was after a mathematics conference. I came to Stanford to store something. This is the third time, how could it be a celebrity at Stanford."

An Yan shook his head, he thought that there might be someone with the same name as him.

He still has a very clear understanding of himself. After all, how could a top university like Stanford University make him a celebrity from a foreign school?

"No, Ann." Pedestrians shook their heads repeatedly and said, "You are a celebrity at Stanford University, maybe you don't know it yourself. There are many discussions about you at Stanford University, which one is more profound in mathematics and physics? A subject that confuses people and finds it very interesting.”

The pedestrian smiled politely at An Yan and said, "I forgot to introduce myself. My name is Green Evelyn, you can call me Green directly. I am currently a bachelor of Stanford University, and I am applying for a master's degree in chemistry."

"I have read a lot of your papers, especially on the graphene experiment." Green said with a smile, "the latest issue of NatureReviewsMaterials has your paper on graphene experiments, very often, I think your chemistry must be It's also very powerful."

Although it was not the first time to be praised so much, An Yan still felt a little embarrassed.Probably because Green on the opposite side was a student of Stanford University with him, it gave him a feeling of confusion.He lowered his head in embarrassment and said, "It's just...just a coincidence."

Green chuckled and said, "If it's a coincidence, then your coincidence and our coincidence are two different concepts."

"I wasted your time. I think Professor Hudson should be working in that small building at this time. I wish you a happy day."

"Thank you, Green." An Yan stretched out his hand to shake Green's hand again to say goodbye, and he continued to walk forward to the small building pointed by Green.And Green has long since left this path.

When he came to the small building, An Yan stood downstairs and raised his head to look at the small building.This seems to be building a family room on campus. Of course, there is no such concept as a family room in the United States.But this small building looks more like a place to live than an office.

Taking a deep breath, An Yan walked towards the small building, pushed open the door, and there was almost nothing underneath.No, there are only two sofas and some simple furnishings, and there seems to be a young man sitting on the sofa.

When he saw An Yan approaching, he stood up and asked, "Excuse me, who are you looking for?"

"I'm looking for Professor Hudson." An Yan said softly, "Is Professor Hudson here?"

"Oh, you are looking for the professor." The man nodded, "The professor is in the office upstairs, do you want me to take you to find him?"

"No need." An Yan stopped and said, "I can go by myself, can you help me look at my luggage?"

"Of course." The man looked at An Yan, "Just arrived at Stanford University?"

"That's right." An Yan showed a smile, "It's true that he just arrived at Stanford University not long ago."

"You're An, right?" The man said suddenly, "In recent years, the professor hasn't accepted any more students, and you are the only student that the professor made an exception to accept."

"The professor is upstairs. I probably don't know that you have arrived at Stanford today. I am the professor's doctoral student, Richard. I am also the professor's assistant. If you have anything to do in the future, if the professor is not here, you can contact me directly. If If I can help, I will definitely help you.”

"Thank you, Brother Richard." An Yan breathed a sigh of relief. It seemed that Professor Hudson's students were very easy to contact.In this way, he seems to be looking forward to studying at Stanford University in the future.

Thinking of this, he put his suitcase aside.He said to Richard, "Please, Brother Richard."

"Exactly, I have nothing to do." Richard smiled at An Yan, "You go up, the professor is not too busy right now. When he gets busy later, he may not have time to talk to you."

"Thank you." After An Yan finished speaking, she hurried up the stairs.

The sound of 'cracking' came from the stairs. Although the wooden stairs were a little solid, there was still a 'creaking' sound.This kind of feeling made An Yan a little strange, no matter whether it was the first floor or the second floor, the floor was paved with marble.Only the stairs, made of planks.

Once upstairs, Richard pointed to the left, indicating that the professor's office was on the left.Taking a deep breath, An Yan walked to the left.This was the first time he met Professor Hudson. When he and Professor Benson came to Stanford University for a physics conference, Professor Hudson seemed to be on vacation and did not attend that academic conference.

When he came to the wooden gate, An Yan took a look. The corridor was sunny and looked a little lazy. There were several rooms next to it, all of which were equipped with small blackboards and some materials, but there was no one there. , the door is also open.Only this room, the door is closed.Come to think of it, Professor Hudson should be in this room.

He reached out and knocked on the door lightly.

"Please come in." There was a hint of oldness in the deep voice.

An Yan pulled the doorknob and entered the office.Professor Hudson looked at An Yan. He didn't remember that there was an Asian-faced person in his office.

"Are you?" Professor Hudson asked suspiciously.

"Hi, professor, I'm An Yan." An Yan introduced herself politely, "I wrote you an email before."

"So it's Ann." The professor showed a smile. The window was open, and there was a row of green vegetation outside. Looking through the window, it was still a bit pleasing to the eye.As if in a paradise, Professor Hudson has gray hair, but he is still hale and hearty.As if he had endless experience, he pointed to the chair opposite the desk and said, "Ann, sit down."

"Thank you, Professor." An Yan was not polite, and sat on the chair.

At this time, Professor Hudson asked, "Ann, in addition to Li Bo's email, I also received an email from the University of Zurich. Your bachelor's tutor, Professor Benson, told me that you are a very Students who have their own ideas. Perhaps, what you want to do is far beyond the scope of high-energy physics or quantum mechanics."

An Yan didn't speak, just lowered his head slightly, as if he was listening to Professor Hudson's teaching.

"Professor Benson means that I don't have to restrain you. You can do whatever you want. No matter whether you can do it well or not, you have to try it." When talking about this, Professor Hudson said with a smile, "even if Even if Professor Benson doesn't say it, I agree with it."

"I have read your thesis, including your graduation thesis. Yours is different from most of the students I have seen. They may have extraordinary talents in a certain discipline or in a certain professional field. ideas and thinking. And you, in almost the entire discipline, have ideas and wisdom beyond ordinary people. This is where you are different from others, and because of this, you want to study Hilbert spaces and Anshi Space, I didn't stop you."

"This is a phased project, right?" Professor Hudson looked at An Yan kindly.

"That's right, this is a phased project." An Yan admitted very frankly that his own research on this topic is a phased topic.

"Then what are you planning to write for your doctoral thesis? Have you thought about the topic after that, or are you ready?"

"Professor." An Yan said after pondering for a while, "I have prepared two doctoral dissertations, and now I don't know which one to choose."

"Do you want me to help you choose?" Professor Hudson spoke in a very indifferent tone. He is a very kind professor to An Yan.Almost since An Yan walked into the office, he hasn't said a single harsh word, nor has he slapped An Yan once.Seems to have always been an amiable professor.

Hearing Professor Hudson's words, An Yan shook his head and said, "Professor, I want to choose by myself. I can't make up my mind now because I don't know which topic I feel more about when the time comes. Or in other words, I As for which topic I want to study more, I am more inspired.”

"If you want to decide for yourself, I will naturally not stop you." Professor Hudson said with a smile, "I only have one question now."

"May I know what subject you want to study next?"

"NP-complete problems or strong interactions."

Professor Hudson was stunned for a moment, he could still understand the subject of strong interaction force.This is one of the topics that need to be done in high-energy physics, and it depends on whether the experimenter can make more profound topics.But what is the previous NP-complete problem?That was one of the seven mathematical conjectures of the millennium.

This problem, as a physicist, wants to be solved.Almost impossible, and not all physicists are very good at calculations.

Not to mention proficient in mathematics.

For Professor Hudson, this is simply incredible.How could it be possible to really go to study mathematics problems? As a Ph.D. student in physics, the graduation project turned out to be NP-complete problems, which are biased towards number theory.This... Is my graduation thesis a bit off track?

"The topic of strong interaction is not bad. At present, strong interaction has always been a hot spot in high-energy physics. It's just that this NP-complete problem is almost biased towards mathematics and informatics." Professor Hudson said with a frown. "If you are a doctoral student in the Department of Mathematics, I certainly agree with you to complete this project. No, even if you are a doctoral student in the Department of Informatics or Mathematics, I do not recommend you to complete this project." Hudson The professor quickly denied that he agreed with An Yan's own research topic.

Professor Hudson said earnestly, "I don't think it is necessary for you to study this problem during your Ph.D. After all, the NP complete problem is a worldwide problem, and you can solve it if you want to solve it."

"Besides, I'm also a professor of high-energy physics. If your graduation project is an NP-complete problem, let's not talk about whether you can solve it."

"Even if you can research it, but—" Professor Hudson smiled wryly when he said this, "It makes me feel like I am actually a professor of mathematics or information science."
