Scholar’s Starry Sea

Used to observe standing waves, a spring that can almost skip rope, a special instrument that reflects light pressure, a blower that can blow a tennis ball, an angular momentum conservation verifier, etc., etc. ......

These interesting "toys" once again aroused the interest of Bookworms, watching the teachers perform on them with great interest.

On the eighth day, the Instructor Lu Zhi informed everyone that there was a symposium at Yannan Garden in the evening, which talked about the principle of the new camera. I suggest everyone to check it out.

The general Instructor personally informed that everyone still obeyed, so he organized a group and went to Yannan Garden in the evening.

To say that Peking University at night is really very artistic, with winding paths everywhere, a dimly yellow street lamp points to the forest path in the distance, and there are antique buildings on both sides of the path.

If it wasn't for the cold weather, Wu Bin would actually be willing to go out every day.

On the road, Jiang Hang and Zhao Kehan ​​are discussing a mechanics problem in the morning, while Li Yan is patted Wu Bin who is still reading the new book and asks: "Hey, how is your C language research?"

"It's OK, I'm studying strings recently."

"amazing."

"What's so amazing about strings?" Wu Bin looked puzzled .

"I mean you have really studied amazing. Physics is not enough for your headache?"

"Learn to play in your free time."

"amazing."

Li Yan gave a thumbs up and turned to join Jiang Hang and Zhao Kehan's discussion group.

When Li Yan asked about the C language, Wu Bin suddenly felt itchy. His schedule was completely filled by Physics this week. There was no time to read the basic C language books that he brought specially. I really miss it for a while.

Now Wu Bin has done several programming exercises on Teacher Huang's computer, and has completely gained the fun of programming languages.

But once, when he suddenly remembered the stubborn robot that was almost forgotten by him, what if it could not understand the C language?

But in the end, I skipped the thought of'just let it go, learn it first, at worst when the time comes, and then tune this robot'.

When they came to the venue, Wu Bin found that it was not only their camps, but also a lot of students from Peking University. Both sides looked at each other and greeted them in a friendly manner.

Some enthusiastic ones will come up and have a chat. After all, some of them used to be sent to Peking University through competitions. At this moment, they are very cordial to see Wu Bin.

This is the first time Wu Bin has listened to the lecture, but after listening to it, I feel that something is wrong. What about the principle of the new camera? What about new technology? What about academics? Why is the main theme to introduce an optical institute in Shanghai?

"What the hell is this? What about good professional knowledge?" Wu Bin asked Li Yan inexplicably.

"I don't even know if you ask me." Li Yan was equally confused.

At this time, a Peking University boy laughed in and interrupted: "This forum, to put it bluntly, is the introduction to the graduate student enrollment of the Institute of Optics, mainly for us."

"Oh~" Wu Bin nodded, turned around and said, "many thanks for the confusion."

"It's okay~" The Peking University boy smiled heartily and continued to listen to the lecture.

Knowing that they couldn't learn new knowledge, Wu Bin and the others left the venue early after listening for a while. At the same time, they found that other students who came with them were also evacuating.

"It always feels like being pitted to support the venue." As soon as he walked out of the venue, a boy wearing glasses said with emotion.

His name is Zhang Fu, Hu Nan has the highest score in this competition, and he is the most spicy!

Wu Bin once watched him eat crispy fried chili as a snack, and he didn't know if he should say "MMP" in his heart.

"You know which direction you should go to when you learn optics. It's not a loss." Gong Chengwei stretched his waist and turned around and suggested to everyone, "It's not good to go back to the study room so quickly. Shall we go to Weiming Lake at night?"

"No, I want to go to the library."

Wu Bin waved his hand decisively, kidding! After traveling around Weiming Lake on such a cold day and night, his face was probably numb when he walked around the lake.

"Is it cold? I think it's okay." As Zhang Fu extend the hand, I felt the wind for a while, "It's not cold."

"You eat a few tons of chili a day Of course it's not cold..." Wu Bin murmured, "Anyway, some of us are going to the library for a while, should we meet in the study room at 8 o'clock?"

"Also." Gong Chengwei I didn't intend to force Wu Bin and the others, so I left with the students who were interested in visiting the lake.

The remaining one who was afraid of the cold followed Wu Bin and the others to the library.

Riding to the library by bike, Wu Bin pulled down his scarf and breathed in air. Once again, he was impressed by the huge and somewhat ancient buildings in front of him.

The Peking University Library consists of the main library, medical museum, 38 branch libraries, and storage halls. The total area is about 90,000 square meters. The main library in front of Wu Bin occupies more than half. 53,000 square meters.

Wu Bin had a preliminary understanding of this library on the 3rd day.

The entire Peking University Library has more than 11 million literature resources, including more than 8 million paper collections, and more than 300 domestic and foreign digital resources, databases, electronic journals, electronic books and other resources.

Professionalism and depth can be said to be evident.

And when Wu Bin first came, he got various new poses. Originally, he thought that university libraries had more professional literature or books than ordinary libraries.

But he was wrong.

Refer to the consultation to find out. Any questions about the library will be solved in minutes, similar to Taobao customer service.

Let’s find out about the literature search, and the highly cited papers in the research field can be done in minutes.

Knowledge Graph... Well, it is very exciting to understand the colorful visualization graph.

In addition, there are many profound books. Whether you are a language, Physics or something, you can always gain something here, and it is probably limited by Peking University.

Therefore, there is a reason why there are so many people in the library all day long. Whether it is a book or a database on a computer, the university is the most professional.

……

Ninth day, Wu Bin, they ushered in a new professor, who is responsible for teaching...Mathematics.

The professor from the Peking University School of Mathematics looks like energetic and bustling as soon as he enters the classroom. He comes up and talks about dx. In Physics, it is called infinitesimal displacement, and in Mathematics, it is called co-cut cluster.

While speaking, he suddenly patted the podium angrily.

"Just arrange such a few lessons for me! How do you finish!"

But on the 2nd day, the professor just explained the complex function for a while, and suddenly he painted As soon as the wind turned, I started to talk about my anecdotes, always feeling like giving up treatment.

Of course, the level of teaching is still leveraged. The residue theorem and Laplace transform have given Wu Bin a new concept.

PS: Second, the feeling of just writing a book is still pretty good...Should I be able to come back to another chapter?
