It was once said that there is no pure friendship between a man and a woman, so the so-called confidante is purely a rhetoric used by a man to deceive another woman. Shen Yiyi himself felt that such a statement was not unreasonable. But she also found that after eliminating the kind of unorganized and chaotic emotions between men and women, in fact, the dialogue between men and women does not have to be stormy, but can be truly knowledgeable.

At least, on the way to the city library by bus, Shen Yiyi talked very happily with Luo Yu, a little skill control beside him. For a young boy who has a strong interest in mathematics and physics, the proper nouns that popped out of Shen Yiyi's mouth, such as Hilbert space, Möbius rings, Riemannian geometry, Schrödinger's cat, and so on, made this boy feel a fatal temptation from the unknown world. Of course, if there are some wise people who focus on the cause of popular science in later generations, Shen Yiyi's behavior of using some esoteric terms to deceive others to worship can only be described in two words, that is: pretending to be forced! But in this era, especially when people have no way to obtain the overwhelming knowledge on the Internet in later generations, Shen Yiyi pretends to be so stylish and toneful.

Luo Yu was a little sad to find that he originally wanted to shorten the knowledge gap with Shen Yiyi as soon as possible through this trip to the city library; However, he didn't expect that the discussion with Shen Yiyi's classmates along the way made him realize that the gap in knowledge between him and Shen Yiyi was much bigger than he imagined. With such a big gap, how can you catch up? To be honest, he was a little discouraged when he found out about such a fact.

However, as the grandson of Old Man Xiao, especially the little grandson who is regarded as the heir of the mantle by Old Man Xiao. He has been taught since he was a child that boys must never give up easily, and there must be a teacher for threesomes. So such a small discouragement existed for a short time. On the contrary, next, he was even more determined that after he arrived at the library today, he only needed the books recommended by Shen Yiyi. He had to borrow it and go home and nibble it carefully. This summer, no matter what, he has to make up for his studies to make up for what he didn't understand before, even if it is not easy to catch up with the knowledge level of Shen Yiyi's classmates, at least he must ensure that he can't be left too far behind. Luo Yu secretly made up his mind, starting from tonight, he must work hard.

In the 90s, Shenyang still had economic debts. Therefore, although it has begun to plan the investment in culture and education, whether it is the provincial library or the municipal library, it is actually not as large as that after the reconstruction of later generations. At a time when the economy has not yet taken off, the first thing to be solved is the material needs of the common people, and as for the spiritual needs, they can only be put aside for the time being. At this point, Shen Yiyi himself thinks it is a very practical approach. The government has only a small amount of resources. Investing in one place means spending less in another place. Of course, we must first invest in the most basic places. The kind of person who demands that the government should do the best to do all aspects of pepper-faced methods, Shen Yiyi has only one evaluation of this kind of person, that is, the too young, too simple Tucson is obviously just a person who can only talk and have no practice. This kind of person will only talk on paper, and if they toss according to their own ideas, they can only ruin the fate of the country. Just like the Donglin Party at the end of the Ming Dynasty. That's it.

Although it has not been rebuilt, Shen Yiyi has always believed that the library is not determined by how modern or luxurious the building is, but by the number of books in the library, as well as the depth and breadth of the collection. What makes Shenyang stand out in the Northeast is that it is blessed with two treasure troves of books in the Northeast. Shenyang City Library and Liaoning Provincial Library. All of them existed long before the establishment of the people's power, so the richness of the collection of books inside speaks for itself. Of course, Shen Yiyi was not very interested in the ancient book collections of these two libraries. She's not a researcher. The main purpose of her and Luo Yu's coming here today was to find some books on mathematics and science. These books were added to the collections of these two libraries after the liberation.

Also, because today I want to find some relatively basic study books for Luo Yu, there is no need to go to the provincial map, and I believe that Shen Yiyi will be able to meet the requirements directly in the city map. Because there are two better libraries at the same time, more people tend to give priority to the provincial library when they are looking for some materials, resulting in the provincial library being more crowded and the number of books borrowed is also more. Shen Yiyi believes that in comparison, for some of the more popular books, the city library should keep some on the shelves that have not been borrowed. That's what she came to after planning with her little brain. When discussing with Luo Yu in the car, he told Luo Yu about this reason, and Luo Yu also agreed with it. In fact, it doesn't matter if you don't agree, in fact, this year, the two libraries are still very close to each other, and if you can't find one library, it doesn't take much time to walk to the other.

Just as Luo Yu gave the information, just showed her student ID, and she and Luo Yu successfully entered the reading area under the caring eyes of the library staff. When passing by the door of the library, Shen Yiyi also heard whispers among the staff: "In the end, it is a student of a key middle school, and he doesn't forget to come to the library to read books even when the Chinese New Year is approaching, which is much more worry-free than the little ancestor in my family." ”

Shen Yiyi listened to it and thought hypocritically in his heart, alas, what are you doing with your ears so good, knowing that others are so envious of you will really make you flutter. Of course, for this kind of obviously envy and praise, Shen Yiyi's style must be directly listened to in his ears, and then he will be in a better mood all day.

So Shen Yiyi, who was in a good mood, had a smile on the corner of her mouth, and asked Luo Yu to go to Advanced Mathematics to find a book called "Vector Analysis" first, and she herself went to the book of force and quantity to find a few textbooks on fluid mechanics, which were convenient for Luo Yu to explain for a while. After the two separated, Shen Yiyi checked the titles of the books in the middle of the shelves by himself along the shelves to determine what kind of books were hidden in this row of shelves. That's right, if you look for a book in the library, if you don't like to flip through the book card, you can just look up calligraphy like a dictionary. In this era, there is no computer management, so there is no way to type the title of the book in the computer, and you can get the call number with a click of the mouse, and you must go to the small grid on the edge of the reading room to turn over the book cards. Shen Yiyi has always been grateful for this kind of monotonous and laborious work, and she can hide, so she simply uses what she calls "looking up the dictionary to find calligraphy" to find the book she wants to find.

An Zhusheng has been in the city library for a day today. It's actually his habit. He knows that he is getting older, and his entire thinking ability and memory are declining, so he consciously creates opportunities for himself to use his brain. So when he wasn't working, he used to bring a big glass of water and a loaf of bread early in the morning to the city library to read books. He regarded reading, especially math and physics, as a form of intellectual gymnastics. Of course, often flipping through some basic books is also a good habit he has developed since he was young. Originally, every basic knowledge was acquired through intensive memory such as repeated reading.

When he was a little strange today, there were suddenly two people who looked like middle school students on the science shelves, which were empty in the past. The boy went to the math bookshelf, but the girl walked to her own mechanics shelf. Although her eyes were clearly on the bookshelf as she walked this way, she often looked at it only and then continued to walk forward. Seeing the little girl getting closer and closer to herself. An Zhusheng felt a little puzzled in his heart. The books here are far beyond the requirements for high school students, and even some college students may not be able to understand these books when they come here to read them, what kind of books does this girl go to read here?

Shen Yiyi looked at the titles of the books on the shelves, obviously approaching the book he was looking for. Looks like that's pretty much it. She consciously slowed down her search for the book and carefully read it one by one. On the one hand, she wanted to find a fluid textbook for Luo Yu, and on the other hand, she also wanted to see if there were any useful and good books here that she had never seen before. The print run of professional books is generally small, so for her, who had only visited the library in Shanghai before, she also had the idea that she might be able to find something here that she had never seen before.

Through the gap between the books and the shelves on the shelves, An Zhusheng found that the girl had stopped and stood opposite him. He remembered it as a bookshelf for fluid mechanics. Could it be that this girl can already read such a book? Fluid mechanics is the most difficult branch of mechanics. Moreover, as a type of continuum mechanics, fluid mechanics also has high requirements for the foundation of mathematics and mechanics. As far as An Zhusheng understands, the knowledge points of the fluid mechanics books on this bookshelf must be far beyond the knowledge of a high school student. There is even a partial differential equation in it, which makes some college students, including some new technicians who have entered their 606 Institute, quite a headache, does this girl not feel any of these? (To be continued......)

PS: It's a little late, but I'm still working on it.

Today must be the second watch, as for the third watch, if it is not sent today, it will be sent tomorrow morning.

In short, I need your support.
