God of black technology

No, you Princeton is too time-sensitive, right?Know what his subject is so soon?Wang Yun was stunned and did not speak on the spot. The white man stretched out his hand and said, "My name is Quentin Jackson. I am a graduate student in the Department of Mathematics. I have read several of your papers. They are very good."

When talking about this, Quentin gave Wang Yun a thumbs up and said, "Especially about the current optimal solution of the NS equation, which touched me very much. I think, even as a pure mathematician, you still need to understand Some physics would be nice."

"By the way, I remember, you seem to be very good at physics, right?"

"I'm not particularly good at it." Wang Yun said shyly, "I just do some research on fluid mechanics, and I want to learn more from Professor Witten in quantum science."

"Oh." Quentin was a little disappointed, "I thought you had some research on particle physics."

"Sorry, there is really no research here." Wang Yun said to Quentin, while trying to leave the dormitory.Quentin looked at Wang Yun while expressing regret, "Are you going to eat?"

"Oh, no." Wang Yun shook his head, "I'm going to the library to find some information about algebraic topology and differential topology."

Quentin smiled knowingly, "I see, you should know where the library is going?"

"Yes, I know." Wang Yun nodded, "Thank you, Mr. Quentin."

"It's ok."

After leaving Quentin, Wang Yun walked out of the dormitory alone and walked on the road in Princeton, looking at the Gothic building in front of him, with a smile on his lips.

It seems that Princeton's academic atmosphere is indeed very strong.The students coming and going were in a hurry, as if they were busy with something.

Walking to the library, Wang Yun took out his ID, found materials and literature on algebraic topology, and started to study it slowly.He was reading a little late, and when he raised his head again, the whole sky was already glowing with a layer of silver light, which was moonlight.

The student in the front is holding a document in his hand, and the computer is on the table, as if he is writing something.

Wang Yun was stunned for a moment, but he had forgotten that he could also bring a computer to the library.Hey, I forgot such an important thing.

Taking the book, walked out of the library, Wang Yun returned to the dormitory.He took out his draft paper, opened the literature, and tried to solve Kakutani's conjecture.Of course, in such a short period of time, his desire to unravel the Kakutani conjecture was purely dreaming.

But he can try to write a beginning, comparing the literature and guessing at the same time.After Wang Yun thought for a while, he began to write.

The sound of 'shashasha' echoed throughout the dormitory, and there was no one else in the dormitory.The sky outside was getting darker and darker. Wang Yun turned on the desk lamp and squinted at the draft paper on the table.After thinking about it for a while, he shook his head.No, so I don't even know how to solve the first step.

No matter how you write, it doesn't seem right.

There must still be something missing, Wang Yunming thought hard, but he still couldn't figure it out.

Don't worry... This is Princeton, a place where monsters gather. Maybe occasionally, others will give me some kind of inspiration.

Wang Yun shook his head, he felt that he was a little too eager for quick success.Obviously, he just arrived in Princeton, not even a day, how could he untie it so quickly.Putting down the pen in his hand, Wang Yun rubbed his eyebrows.Standing up and tidying up, he decided not to think about this issue for now.

After taking a shower, Wang Yun went to bed after washing up.

When I woke up the next morning, I was woken up by Yuan Chengde's knock on the door.Rubbing his eyes and opening the door, Wang Yun saw Yuan Chengde standing outside the door, looking a little anxious.He froze for a moment, "What's wrong with you?"

"There is a class today, have you forgotten?" Wang Yun nodded and yawned, "What class is it today?" If it wasn't for algebraic topology, he wouldn't be going to class.It's better to just continue to study your own things in the library.

"Today I'm going to explain topology. I think you can listen to it. Although it's not algebraic topology, the professor will give you some novel ideas about topology, which may be useful to you." Yuan Chengde praised The textbook in his hand said, "You haven't gone to get the textbook yet, have you?"

"Hmm..." Regarding the matter of textbooks, Wang Yun really didn't know where to get them.I heard that new textbooks are quite expensive in American University.He is very confused now, whether he should go to pick up the books, or...buy old books from senior seniors.

"I remember you applied for full tuition waiver and scholarship, right?" Yuan Chengde raised his brows and said, "I only applied for full tuition, and the scholarship is really too difficult to operate, and I can't get it at all."

"So, if the tuition is free, you can get the textbooks for free?" Wang Yun asked, and Yuan Chengde nodded.

When I came to the classroom with Yuan Chengde, looking around, it was almost crowded.Fortunately, not many people spoke, and the whole classroom was quite quiet.Although Wang Yun is also a person who often attends lectures in the lecture hall, generally speaking, the class that attends lectures is at most 100 people.

Moreover, not every class is a combination of several classes.

The classrooms in Princeton are large classrooms with 100-150 people in each class.In a place like Princeton, if you don't work hard, it is impossible for general professors and teaching assistants to call names.Either you fail the exam and go home, or you fail the graduation thesis and go straight to school.

It is a test of students' self-learning ability. In this environment, if a student has no self-learning ability, I am afraid that he will be dismissed within two semesters.

TAO, who once stayed in Princeton, seems to have almost been expelled by Princeton.

Just thinking about it, the professor has already walked into the classroom.He didn't care whether the students below attended the class or not, but started to explain directly.Wang Yun and Yuan Chengde read a topology book together, because it was taught in English, Wang Yun was not used to it at first.

After about 20 minutes, Wang Yun finally got used to this teaching method, and listened carefully to the professor's explanation.Looking at the professor on the podium, who was only in his thirties, Wang Yun smiled slightly and did not speak.If such a professor is in China, once someone puts it on the Internet, it may cause some turmoil.

It's not because of other things. It seems that in the minds of Hua people, professors can only be people in their 40s.If you become a professor in your 20s, you will definitely be questioned all the time.

When the professor finished his lecture, he looked at everyone in the large classroom of more than 100 people and asked, "Anyone else have any questions?"

No one in the classroom spoke, "Well, it seems that today is another peaceful day." The professor said humorously, "Perhaps, I should thank you for not letting me down."

"Hahaha..." There was good-natured laughter in the classroom, and when the professor left, Yuan Chengde began to pack his things.Wang Yun was still a little puzzled, "Let's go now? Don't you assign homework?"

"The homework is basically a small topic for group discussion. If you want something like homework, I believe Professor Witten is very happy to provide it for you."

Forget it, Wang Yun always felt a little awkward when he thought of Professor Witten's serious face.In half a year, if you can't solve the Kakutani conjecture, you will have to work for Professor Witten.Of course, it is a great honor to be able to work for Professor Witten. You have to know how many people want to work for Professor Witten, but there is no such opportunity yet.

But Wang Yun is Wang Yun after all, different from others!

If he didn't solve Kakutani's conjecture, he would definitely not be reconciled.

"What's the next class?" Wang Yun looked at Yuan Chengde next to him. "The next class should be linear operators. You should be familiar with functional analysis."

"It's relatively familiar."

"Come on, let's go to the next class." Yuan Chengde stood up and started walking to the next class.The person attending the class this time was a teaching assistant. Wang Yun just walked into the class and found that there were not many people coming, so he took a good position in front. After a while, an old man walked up to him, looked at him carefully, and sat down. next to him.

Wang Yun didn't pay attention either, thinking to himself, maybe another professor came to attend the class.This kind of thing is not common in Beijing University, but it is not uncommon.He even saw with his own eyes that Professor Chen quietly walked into the classroom through the back door of the classroom, and sat in the back row to listen to the class.

For this kind of thing, it is not surprising.

On the other hand, Yuan Chengde, who was next to him, seemed a little nervous after seeing the old man.

Wang Yun instantly understood that the person sitting next to him was probably a big boss.When all the students arrived, the teaching assistant walked in without paying attention to the old man sitting in the front row.

As soon as the lecture started, it seemed that the students in Princeton were no longer surprised by the fact that the boss was listening to the lecture.

Regarding functional analysis, Wang Yun can be regarded as having some experience.The speed of the teaching assistant's lecture is not fast, and it is all the knowledge he knows.

When the teaching assistant explained the linear conversion, Wang Yun frowned slightly, and the old man next to him also bowed his head in thought.

The teaching assistant was still talking on his own. After a while, the old man turned his head to look at Wang Yun and said, "You also found something wrong?"

Wang Yun nodded, "There is something wrong with the linear conversion. I'm not sure if it's a calculation problem or a problem with himself." Wang Yun was silent for a while, "I feel like there's a logical break."

"That's right." The old man nodded, "It's almost the same as I thought, but——I know exactly where he went wrong."

The old man smiled and said, "Aren't you curious?"

"Of course." Wang Yun also laughed along with the old man, "Then you can do the calculation for me, what is wrong?"

"I have a question!" The old man stood up, and the teaching assistant who was still lecturing froze for a moment, looking at the old man who stood up and spoke.He gasped.
