Chapter 129

A spring that is almost as long as a skipping rope for observing standing waves, a special instrument that reflects light pressure, a blower that can blow up tennis balls, an angular momentum conservation demonstrator, etc., etc...

These interesting "toys" once again aroused the interest of the top students, who watched the teacher perform on them with great interest.

On the eighth day, the head coach Lu Zhi informed everyone that there would be a symposium at Yannan Park in the evening, which was about the principles of new cameras. He suggested that everyone go and take a look.

The head coach personally informed him, but everyone still obeyed, so they went to Yannan Park in a group at night.

Peking University at night is really very artistic, with winding paths everywhere, a dim streetlight pointing to a forest path in the distance, and antique buildings on both sides of the path.

If the weather hadn't been too cold, Wu Bin would actually be willing to go out for a walk every day.

On the way, Jiang Hang and Zhao Kehan ​​were discussing a mechanics question in the morning, while Li Yan patted Wu Bin, who was still reading a new book, and asked, "Hey, how is your C language research going?"

"It's okay, I've been studying strings recently."

"Awesome."

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

"I mean you've actually gone on to study so much that it's awesome. Physics alone isn't enough to give you a headache?"

"Let's learn and have fun in our free time."

"Awesome."

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

When Li Yan asked about C language, Wu Bin suddenly felt itchy. His schedule this week was completely filled with physics, and he didn't have time to read the basic C language books he brought specially. He really missed it at the moment.

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

But one time, when he suddenly remembered the pure robot that he had almost forgotten, he thought what if it couldn't understand the C language?

But in the end, I skipped it with the idea of ​​'whatever, learn it first, and at worst, train this robot later'.

When they arrived at the venue, Wu Bin and the others found that they were not the only ones from the training camp. There were also many students from Peking University. Both sides looked at each other and then said hello in a friendly manner.

Some enthusiastic people would even come up to chat. After all, some of them had been admitted to Peking University through competitions. Now they felt more cordial to see Wu Bin.

This was Wu Bin's first lecture, but as he listened, he felt something was wrong. What about the principles of new cameras that he agreed to talk about? What about new technology? What about academics? Why is the main theme introducing an optical institute in Shanghai?

"What are you talking about? Where's the professional knowledge you promised?" Wu Bin looked at Li Yan inexplicably and asked.

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

At this time, a male student from Peking University in the back smiled and interjected: "This symposium is, to put it bluntly, an introduction to the postgraduate admissions of the Institute of Optics. It is mainly for us."

"Oh~" Wu Bin nodded, turned around and said, "Thanks for clarifying."

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

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

"I always feel like I'm being tricked to keep the show going." As soon as they left the venue, a boy wearing glasses who was walking at the front said with emotion.

His name is Zhang Fu, Hu Nan has the highest score in this competition, and he is also the one who can eat spicy food the best!

Wu Bin once watched him eat crispy peppers as snacks, and he didn't know whether to say "MMP" in his heart.

"You know what direction you should go after studying optics, so it's not a loss." Gong Chengwei stretched out, turned around and suggested to everyone: "It's not good to go back to the study room so soon. How about we go on a night tour in Weiming?" lake?"

"No, I'm going to the library."

Wu Bin waved his hands decisively, just kidding! It was such a cold night to visit Weiming Lake. His face was probably numb from the cold as he walked around the lake.

"Is it cold? I think it's okay." Zhang Fu stretched out his hand to feel the wind. "It's not cold."

"Of course you are not cold after eating tons of chili peppers a day..." Wu Bin complained, "Anyway, we are going to the library to hang out for a while. How about we meet in the study room at eight o'clock?"

"Okay." Gong Chengwei didn't intend to force Wu Bin and the others, so he took the students who were interested in going to the lake and left.

The remaining ones who were afraid of the cold followed Wu Bin and the others to the library.

After riding his bike to the library, Wu Bin took off his scarf and took a breath of air-conditioning. He couldn't help but be impressed again by the huge and somewhat ancient building in front of him.

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

On the third day, Wu Bin had a preliminary understanding of this library.

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

The professionalism and depth can be said to be evident.

And when Wu Bin came here for the first time, he got all kinds of new ideas. He originally thought that the university library had more professional documents or books than ordinary libraries.

But he was wrong.

Please refer to the consultation service to find out more. Any questions about the library will be solved for you in minutes, which is similar to Taobao customer service.

Learn about literature search. Highly cited papers in the research field can be retrieved in minutes.

Knowledge graph... Well, let’s learn about the colorful visual graph. It’s very exciting.

In addition, there are a lot of advanced books. No matter you are engaged in language, physics or whatever, you can always gain something here, and it is probably limited to Peking University.

Therefore, there is a reason why so many people in universities spend all day in the library. Whether it is books or databases on computers, universities are the most professional.

…

On the ninth day, Wu Bin and the others welcomed a new professor, who was responsible for teaching... mathematics.

This professor from the School of Mathematics at Peking University was in a hurry as soon as he entered the classroom. He came up and talked about dx. In physics, it is called infinitesimal displacement, and in mathematics, it is called cotangent bundle.

As he was speaking, he suddenly slapped the podium angrily.

"Just give me these few classes! How can I finish them!"

But on the second day, after the professor had just explained the complex function for a while, he suddenly changed his tune and started telling his own anecdotes, which made him feel like he was giving up on treatment.

Of course, the teaching level is still excellent. Wu Bin has new concepts in the area of ​​residue theorem and Laplace transform.

PS: Second update, it feels good to just write a book... maybe there will be another chapter?
