After sending his parents and sister out of the community, Mu Jingchi did not go home, but began to wander along the streets around the community.

Although there is a system, it will not make him indigestion after eating.

But taking a stroll outside and taking a walk is still very good for one's body and mind.

During the day, I work on projects in the laboratory, and only when I have dinner do I come out to see the scenery outside, and at night I have to go to the study to continue studying.

Therefore, there is not much time for Mu Jingchi to recuperate.

The area of the city is still very large, and there is a square outside the north gate, where many grandmothers and grandfathers in their 50s like to dance.

After the square dance was passed for a while, some other grandparents took over the craft.

took out the erhu and flower drums, and sang while playing musical instruments.

Outside the square is the street, two-way four-lane, in the middle of which is isolated by planted trees and flowers, Mu Jingchi walked along the street, his eyes swept around casually.

At this time, there is no need to think about the material, and there is no need to think about the experiment in the subject, and the eyes only contain the simple life situation.

The first thing that catches your eye is the rookie express, several express delivery companies gathered together, there are Yuantong, Zhongtong, Yunda, and Jingdong.

At this time, many people are receiving the parcel at their respective stores.

Next to it is the fresh fruit storefront, and with the development of planting technology, out-of-season vegetables and fruits are not a new thing, so there are many kinds of fruits on display.

Office workers who have just worked overtime, parents with children, are all picking fruits and vegetables.

Next to the fresh fruits, there are naturally all kinds of dining shops in the community, including hot pot, barbecue, spicy hot, yellow braised chicken rice, S County snacks, Lanzhou ramen and so on.

Walking all the way, Mu Jingchi looked at these people.

The scenes of life also infected him, allowing him to gradually and imperceptibly integrate into it, without making him a researcher who lacks the breath of life.

After going around the entire Shengjing Charm City, Mu Jingchi returned home.

I poured myself a glass of warm water and went into the study to begin studying.

Mathematics is the foundation of all sciences.

Some people say that all the problems in the world ultimately boil down to physical problems. Physics problems, in the end, are all mathematical problems.

This shows the weight of mathematics.

Of all the disciplines, mathematics stands at the top of the chain of contempt. And those who engage in pure numbers despise those who engage in numbers.

Mu Jingchi is naturally ready to take the path of applied mathematics.

Since you have the idea of strengthening your own mathematical ability, you should do it thoroughly, go directly to the path of mathematics students, and move forward according to the path of mathematical thinking.

There is no advanced mathematics in the mathematics department, they study mathematical analysis and advanced algebra.

Of course, the Department of Mathematics is definitely not only these two courses, but now Mu Jingchi is starting from these two courses.

In his freshman and sophomore years, Mu Jingchi naturally studied related mathematical knowledge, such as advanced algebra, linear algebra, probability statistics and random processes, etc.

But compared to the specialized mathematics department, it is still inferior.

With the help of the system's function of 'active thinking', Mu Jingchi is very serious about the study of mathematics.

Mathematics is a rigorous and abstract subject.

In Mu Jingchi's heart, mathematics is beautiful.

It's just that this kind of beauty is not felt by ordinary people.

When examining art, we can rely on our auditory, visual and even tactile senses to truly feel the charm of art, such as classic and beautiful songs, wonderful movies, profound paintings, and magical architecture.

Maybe we can't put into words this feeling about art, maybe only 'a sentence that sleeps in the world' can express our shock.

But we really felt it.

However, the beauty of mathematics is only a general feeling for ordinary people, such as surface subdivisions and minimath surfaces in various buildings, Möbius strips, catenary lines, symmetrical structures, ring structures, single-page hyperboloids, golden sections, and so on.

Or the various plant forms that exist in nature.

As for the deeper beauty of mathematics, most people don't have that ability, because that requires talent and intelligence.

When you see a mathematical model, can you feel the beauty of the data forming the model? Can you see the internal connection between a series of data that exists in the software? Can you feel the rigor of the abstract logic that exists in the imagination?

If you can, then you will be able to understand the beauty of mathematics in depth.

The current Mujingchi is such a state.

Mathematical analysis and advanced algebra are the foundations of mathematics, but they are also very enjoyable to learn. The mathematical knowledge and material knowledge in the mind collide with each other, stirring up more sparks of thought.

These sparks, in turn, promoted the absorption of mathematical knowledge by Mu Jingchi and the construction of a mathematical knowledge system. Although this is only the foundation, it is only the beginning of the construction of a mathematical knowledge system, but it has already begun to sprout.

"Let me tell you," Mu Huaiyun, who had already taken a bath and was leaning on the bedside, saw Lao Ji lift the quilt and go to bed, officially opening this topic of secrets, "I think Xiao Mu has a girl she likes." ”

As soon as he heard this, Lao Ji hurriedly got into the quilt, and he was also interested, leaning his back on the pillow.

"How do you tell?"

"I'll give you an analysis. Lao Mu flasped his fingers and began to sort out the details, "Do you think Xiao Mu's personality has changed a lot?"

"Great!" Lao Ji said sure and affirmative of this, and nodded.

"When did that start?" Lao Mu guided the topic in the form of questions and answers, and asked another question.

"It seems to be a graduate student, right?" Lao Ji thought carefully, "When he stepped into graduate school, Xiao Mu had to move. Not to mention, since he moved, his personality has changed, and he is a little more lively and cheerful. ”

Although he still doesn't like to talk coldly, he can still see the difference in front of familiar people. ”

Syllable!

Mu Huaiyun snapped her fingers, "Yes, it changed after moving." ”

"That's the point!" Lao Mu looked a little like Detective Conan at this time, and the temperament in his eyes that saw through everything could be described as pinched.

"After moving, I met Song Xiaoyi next door. ”

"My family is Xiaomu, I like people. ”

Lao Ji was really stunned at this moment, "Huh?

Restructured families, whether children or parents, are actually very sensitive. Such a mind will also make them pay extreme attention to detail in their lives, paying attention to the way they speak and the tone of their voice.

Under such circumstances, Lao Ji really didn't notice Mu Jingchi's emotional abnormality. As for the character becoming more lively, it can be attributed to the growth and maturity of the mind.

"Of course I found out by talking to him. Lao Mu told the conversation with Mu Jingchi before the meal just now.

At that time, I asked Xiao Mu if he had a fancy for someone, but Xiao Mu changed the topic. I feel very strange, for so many years, I know best what Xiao Mu's personality is, and when it comes to girls, he almost doesn't care at all. ”

"This time the subject is completely wrong. ”

"You can't be mistaken, right?" Lao Ji still felt unreliable, "Just changing the subject is not enough to prove it, what if you ask too many questions and he doesn't want to continue this kind of uncaring topic?"
