"Teacher Ye? You...... Are you here? ”

"Are you...... Xiao Luo, right? ”

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

"That day, I knew that her fiancé Ding Yi buried her here, and I knew this place, a very good place, and it was convenient to take a car, and I often came here for a walk recently."

"Teacher Ye, you, you want to mourn."

"Oh, it's all gone......"

The brown ant on the lonely peak wanted to turn and climb upwards, but found that there was a groove in front of it, which was exactly the same as the shape "9" it liked before the "7", so it went sideways and climbed this "9" again.

It thinks that this shape is better than "7" and "1", and of course it is impossible to say what is good, this is the primitive single-celled state of beauty; The vague pleasure of climbing over "9" just now is strengthened again, which is the primitive single-cell state of happiness. But the single cells of these two spirits have no chance of evolving, and they are the same now as they were 100 million years ago, and the same 100 million years will be the same.

"Xiao Luo, Dongdong often mentions you, she says you are...... Doing astronomy? ”

"It used to be, now I'm teaching sociology at university, and I'm going to school where you're and teaching at another school, but when I started teaching, you're retired."

"Sociology? Such a big span? ”

"Yes, Yang Dong always said that my heart is very scattered."

"Oh, no wonder she said you're smart."

"It's just clever, not on the same level as your daughter. I just feel that the astronomy major is ironclad, and it is not easy to drill an eye anywhere; Sociology and the like are wooden planks, and you can always find some thin places to drill through, so it's easier to mix. ”

With the desire to encounter another "9", the brown ant continued to run rampantly, but what it encountered in front of it was a straight horizontal groove parallel to the ground, as if the first groove was placed horizontally, but it was longer than "1", and there were no small grooves at both ends, in the shape of "one".

"Don't say that, this is a normal person's life, how to do it like Dongdong."

"I'm really ambitious and impetuous."

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

"Cosmic sociology?"

"A term I casually say is to assume that there are a huge number of civilizations distributed in the universe, and their number is an order of magnitude with the number of stars that can be observed, many, many, many, and these civilizations constitute an overall cosmic society, and cosmic sociology is the study of the form of this super-society."

The brown ant on Lone Peak continued to climb sideways for a short distance, expecting to find a "9" it liked after climbing through a groove shaped "one", but it encountered a "2", the front part of the route was comfortable, but the sharp turn behind was as terrifying as the "7" in front, which seemed to be a bad omen.

The brown ant continues to climb sideways, and the next groove is a closed shape: "0", this kind of distance is part of the "9", but it is a trap: life needs to be smooth, but it also needs a direction, and you can't always go back to the starting point, and brown ants understand this. Although there were still two grooves ahead, it had lost interest and turned to climb upwards.

"Yes...... At present, we only know our civilization. ”

"That's why no one is going to do this, so it's a chance for you."

"Teacher Ye, it's very interesting! You go on. ”

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

"Why?"

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 it was easy to count.

It is easy to recall the sky when not a single star appeared, and the blue void revealed a vast blankness, like the pupilless eyelids of a marble statue.

Now, although the stars are scarce, this huge empty eye has a pupil, so the emptiness has a content, and the word universe has a vision. But compared to space, the stars are so small, just a faint silver dot, which seems to hint at some kind of uneasiness of the cosmic sculptor—he (it) cannot overcome the desire to give the universe a pupil.

But there is a certain great fear of the vision of Fuzi, the eye of the universe, and in the end, the immensity of space and the tininess of the stars are the result of this balance of desire and fear, indicating a certain caution that transcends everything.

"You see, the stars are all points, and the complex structure of various civilizations and societies in the universe, in which the chaotic and random factors, are filtered out by such a huge distance, and those civilizations seem to us to be points with parameters, which is relatively easy to deal with mathematically."

"But, Mr. Ye, the cosmic sociology you mentioned does not have any actual data for research, and it is unlikely that it will be investigated and experimented."

"So your final result is purely theoretical, just like Euclidean geometry, first set a few simple axioms that are not self-evident, and then deduce the whole theoretical system on the basis of these axioms."

"Teacher Ye, this ...... It's so interesting, but what is the axiom of cosmic sociology? ”

"First, survival is the first need of civilization; Second, civilization grows and expands, but the total amount of matter in the universe remains the same. ”

The brown ant climbed a short distance upwards to realize that there were also grooves above, and it was a combination of a bunch of grooves, and the structure was as complex as a maze. The brown ant is sensitive to shapes, and it is confident that it can figure out the shape, but it has to forget about the shapes that have crawled in front of it, because its small neural network has a limited capacity.

It doesn't regret forgetting "9", it's a part of its life that it keeps forgetting, and there aren't many things that it must remember for the rest of its life, all of which are genetically engraved in the part of the storage area called instinct.

After emptying its memory, it enters the labyrinth, and after a tortuous crawl, it builds up the shape in its rudimentary consciousness: "tomb".

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

It first crawled into a graceful groove, a form that reminded it of the belly of a recently found dead grasshopper. It quickly figured out the structure: "of".

Later, on the upward climb, two groove combinations were encountered, the former one included two drop-shaped pits and a grasshopper belly - "winter"; The top one is divided into two parts, which are combined to be "Yang".

This was the last shape the brown ant remembered, and the only one it remembered during this climb, and the interesting shapes that had climbed before it were forgotten.

"Mr. Ye, from a sociological point of view, these two axioms are solid enough...... You say it so quickly, as if you have a clear idea. Luo Ji said with some surprise.

"I've been thinking about it for most of my life, but it's the first time I've talked about it, and I really don't know why...... Oh, and to deduce the basic picture of cosmic sociology from these two axioms, there are two more important concepts: the chain of suspicion and the technological explosion. ”

"Two very interesting terms, can you explain?"

Ye Wenjie looked at his watch: "There is no time, in fact, you are so smart, you can come up with it yourself, you can start with these two axioms to create this discipline, then you may become the Euclidean of cosmic sociology." ”

"Teacher Ye, I can't become Euclid, but I will remember your words and try to do it, and I may ask you again in the future." Finish. ”

"I'm afraid I won't have a chance...... Or, you just say whatever it is, I did my duty. Okay, Xiao Luo, I'll go. ”

“…… Mr. Ye, take care. ”

Ye Wenjie left in the twilight and walked to her final party......
