"Teacher Ye? You...are you here?"

"You are... Xiao Luo, right?"

"Yes, Teacher Ye, I am Luo Ji, Yang Dong's high school classmate. Today I came to see her for the first time. What are you..."

"I found out that day that her fiancé Ding Yi buried her here. I found out about this place. It's a very nice place and it's convenient to take a car. I often come here for a walk recently."

"Teacher Ye, please show your condolences."

"Oh, all this has passed..."

The brown ant on the solitary peak originally wanted to turn around and climb up, but found that there was a groove in front of it, which was exactly the same as the shape "9" it liked before climbing over "7", so it walked across it again and climbed the groove again.

"9".

It feels that this shape is better than "7" and "1". Of course, it can't explain why it is better. It is the primitive single-cell state of beauty. The vague sense of pleasure when it just climbed over "9" has been strengthened again.

It is the primitive single-cell state of happiness. But the single cells of these two spirits have no chance to evolve. They are the same now as they were hundreds of millions of years ago, and they will be the same in the same billions of years.

"Xiao Luo, Dongdong often mentions you. She said you are... engaged in astronomy?"

"It used to be, and now I teach sociology in college. The school I went to was the same school you were in, and the one I taught was in another school. But when I started teaching, you had already retired."

"Sociology? Such a big span?"

"Yes, Yang Dong always said that I have a very loose heart."

"Oh, no wonder she said you are very smart."

"Just a little clever, not on the same level as your daughter. I just feel that the astronomy major is a monolith, and it is not easy to drill a hole anywhere; while the sociology major is like a wooden board, and you can always find some thin spots to drill through, which is better.

Let’s mix it up.”

With the hope of encountering another "9", the brown ants continued to run rampant, but what they encountered in front was a straight horizontal groove parallel to the ground. It seemed that the first groove was placed horizontally, but it was smaller than "1".

"Long, without small grooves at both ends, in a "one" shape.

"Don't say that. This is a normal life. How can we behave like Dongdong?"

"I really have no ambitions and am very impetuous."

"I have a suggestion: why don't you study the sociology of the universe?"

"Cosmic Sociology?"

"A term I casually mentioned is to assume that there are a huge number of civilizations distributed in the universe. Their number is of the same order of magnitude as the stars that can be observed. There are many, many. These civilizations constitute an overall cosmic society. Cosmic sociology is

Study the shape of this super society."

The brown ant on the solitary peak continued to crawl laterally for a short distance, hoping to find a "9" it liked after crawling through the groove shaped like a "1", but what it encountered was a "2".

The part is very comfortable, but the sharp turn at the back is as scary as the "7" in front, which seems to be an ominous omen.

The brown ants continue to crawl sideways, and the next groove is a closed shape: "0". This distance is part of "9", but it is a trap: life needs smoothness, but it also needs a direction, and you cannot always go back.

When it reached the starting point, the brown ant knew this. Although there were still two grooves in front, it lost interest and turned around to climb up.

"But... we only know about our civilization at the moment."

"Because no one is doing this, this leaves you with a chance."

"Teacher Ye, this is very interesting! Please go on."

"I think so because by combining your two majors, cosmic sociology presents a clearer mathematical structure than human sociology."

"Why do you say that?"

Ye Wenjie pointed to the sky. The twilight in the west was still very bright, and there were so few stars in the sky that they could be easily counted.

This can easily remind people of the sky when not a single star appeared. The blue void revealed a vast blankness, like the eyelids of a marble statue without pupils.

Although stars are very rare now, this huge empty eye has pupils, so the emptiness has content, and the universe has vision. But compared with space, the stars are so tiny, just looming silver dots, as if

It hints at some uneasiness of the sculptor of the universe - he (it) cannot overcome the desire to add pupils to the universe.

But there is also a certain huge fear towards the vision of the eye of the universe. In the end, the hugeness of space and the tinyness of stars are the result of the balance of desire and fear, indicating some kind of caution that transcends everything.

"You see, the stars are all dots. The complex structures of various civilized societies in the universe, including the chaotic and random factors, are filtered out by such huge distances. From our perspective, those civilizations have parameters.

point, which is easier to handle mathematically.”

"But, Teacher Ye, the cosmic sociology you mentioned does not have any actual data for research, and it is impossible to conduct surveys and experiments."

"So your final result is purely theoretical, just like Euclidean geometry. You first set a few simple self-evident axioms, and then deduce the entire theoretical system based on these axioms."

"Teacher Ye, this... is really interesting, but what are the axioms of cosmic sociology?"

"First, survival is the first need of civilization; second, civilization continues to grow and expand, but the total amount of matter in the universe remains unchanged."

The brown ant climbed up a short distance before he realized that there was a groove above, and it was a combination of a bunch of grooves. The structure was as complex as a maze. The brown ant was sensitive to shapes, and it was confident that it could figure out the shape, but for this it had to

Forget about the shapes we crawled through earlier, because its little neural network has limited storage.

It did not feel regret when it forgot "9". Continuous forgetting is a part of its life. There are not many things that it must remember throughout its life. They are all engraved by genes in the storage area called instinct.

After clearing its memory, it entered the maze, and after a tortuous crawl, it established this shape in its rudimentary consciousness: "tomb."

Further up, there is another combination of grooves, but it is much simpler than the previous one. However, in order to explore it, the brown ants still have to clear their memory and forget about the "tomb".

It first crawled into a groove with beautiful lines. The shape reminded it of the belly of a recently dead Grasshopper it found not long ago. It quickly figured out the structure: "Zhi".

On the way up, we encountered two more groove combinations. The first one included two drop-shaped pits and a grasshopper belly - "Winter"; the top one was divided into two parts, which combined were "Yang".

”.

This is the last shape that the brown ant remembers, and it is also the only one that is remembered during this climbing journey. All the interesting shapes that it climbed before have been forgotten.

"Teacher Ye, from a sociological perspective, these two axioms are solid enough... You said it so quickly, as if you were confident." Luo Ji said with some surprise.

"I have been thinking about it for most of my life, but this is indeed the first time I have talked about this with someone. I really don't know why I want to talk about it... Oh, if you want to deduce the basic picture of the sociology of the universe from these two axioms, there are two more

Important Concepts: Chains of Suspicion and Technological Explosion.”

"These are two very interesting terms, can you explain them?"

Ye Wenjie looked at her watch: "There is no time. In fact, you are so smart that you can figure it out yourself. You can start with these two axioms to create this discipline. Then you may become Euclid of cosmic sociology.

"

"Teacher Ye, I can't become Euclid, but I will remember your words and try to do them. I may ask you for advice in the future."

"I'm afraid there is no chance...or, you can just think that I just said it casually. No matter what the situation is, I have fulfilled my responsibility. Okay, Ronaldinho, I'm leaving."

"...Teacher Ye, please take care."
