Chapter 163 Scientific Taxonomy

The three of them walked on the gravel path in the courtyard.

It is lined with manicured lawns, and in front of it is the only small second floor. The clean and elegant environment, the tranquility and serenity that they have not seen for a long time, make them all feel quite good.

Xu Liang: "I remember you said that there are a lot of good things here?" ”

Duan Qing: "Hmm. ”

Xu Liang: "Don't be sloppy, I'm talking about that gun, the matrix cluster machine gun!" ”

Old Xu had been talking about this gun for a long time, and since he had been besieged by those giant termites before, he had especially looked forward to having a strong attack weapon. It is conceivable that if you encounter the enemy on a large battlefield, it is at least better to have a heavy firepower weapon than to hold a machine gun that does not work at all.

Of course, he didn't expect a so-called heavy machine gun, even a futuristic high-tech machine gun with such a cool name.

To put it bluntly, no matter how Niu X is, it's just a gun.

If you are faced with a small force of dozens of ants, it may still have an effect. But in the face of a huge number of enemy troops, it is only a drop in the bucket.

However, no matter what you say, you can't go out to fight monsters in whiteboard equipment like now!

"Where's the gun? Where? Xu Liang looked at the picturesque scenery of private villas around him.

Duanqing said innocently: "How do I know? ”

Xu Liang glared: "!! You told me I had a gun!! ”

Duan Qing also glared: "What is written in the information - this is a weapon specially prepared for civilizations far below the first order, specially used for intra-star operations, weak in power, but high in practicality." ”

"Weak?"

"Yes, it's just weak...... Duanqing's voice became smaller, and then she also said confidently, "It's not that weak." That's a comparison of points, for us now, this is quite a powerful weapon! ”

"Where?"

"The information does not say ......"

"What else do you know, can you tell it all at once?"

"No ......"

Xu Liang felt that he almost spurted out a mouthful of old blood, which was equivalent to saying that he hadn't said it for a long time! You still have to figure it out on your own.

But if you look closely at the environment...... No matter how you look at it, it's just a very high-end villa, and it doesn't look like it can produce a super firearm. Unless there's something weird inside the door?

As he got closer and closer to the door on the second floor, Xu Liang's sense of urgency became heavier and heavier. After all this, even he couldn't tell whether this sense of urgency represented danger or was simply out of haste and urgency.

However, at this time, Duan Han, who had been silently speaking, suddenly listened.

Then, she left the gravel road and walked onto the grass next to her, looking excited.

Xu Liang looked at her, and then at the small courtyard—there was nothing in the courtyard except for the flat grass.

Soon, my sister Duanqing also seemed to have discovered something, and followed my sister down to the grass.

Xu Liang looked at the sisters seriously, and then looked at the grass where they were squatting, with puzzled eyes.

Duan Han: "There's something here. ”

Duan Qing: "Hmm. ”

Xu Liang followed: ?

Duanqing (cold): "Regular geometry. ”

Duan Han squatted on the ground and carefully touched the grass with his hands. Duan Qing said: "If you look closely, the shape of the grass here is very different from the surrounding ones, and if you connect these turf of different colors, it is a regular geometry!" ”

Xu Liang saw it.

"How?"

Duan Qing said seriously: "This is a special structure, which looks a bit like ...... In short, there is an estimate of what device is underneath. ”

When she said this, Duan Han had already reached out to pull the weeds.

Grass is the kind of high-grade turfgrass, neat, beautiful, shiny and shiny. And it's the kind that needs to be built seriously, and in the old world, the middle class of American imperialism was proud of a neatly built meadow, as if it were wearing luxury. Raising grass is similar to raising flowers and vegetables, and you have to be careful. What I mean by this is that the grass is very delicate, and it should come down with a light plucking.

Even if it's a girl like Duanhan, who doesn't have much strength, it shouldn't take much effort to pull out a piece of grass.

But Duanhan didn't pull it out!

I rubbed my hands together!

What kind of regular geometry or something, Xu Liang didn't quite understand. But at this moment, Lao Xu was a little moved. He also pulled a small handful of grass and ......

I can't pull it out!

Am I grass?

"There's definitely something down here!" Duan Han said angrily.

Xu Liang didn't believe in evil, and tried several times, but it was still unsuccessful. These grasses are like the roots of a big tree, and they can eat and hold their strength, and they will not move at all. He took a closer look at the grassroots, where they touched the soil, and found that the soil was also very distinctive.

It's not so much the soil as the floor tiles that look like soil.

Porcelain.

And these wonderful grasses grow on these tiles!

Xu Liang knocked on these "tiles", and a similar knock on the door of "Dangdang" came. Obviously, not only is the tile itself hard, but the underside is also solid.

He shook his head, stood up and pulled the two girls up, "Okay, let's do this first." I guess there's something in there, but we can't figure it out right now, so let's take a look at it first, and maybe we'll be able to solve the mystery of these meadows in a while. ”

The three of them continued to walk towards the small house in the middle, and nothing else happened in the middle, except that the beautiful woman at the door followed me. Behind the three of them, follow slowly, as if a steward follows his master.

The beauty of the light curtain followed quietly, barely attracting attention.

Xu Liang looked back at her several times, but did not find that her "expression" was abnormal. She didn't use it to walk, but floated on the ground, moving in parallel, as if she had anti-gravity.

Xu Liang turned around, and deliberately came to her side, blocking her with clothes, wanting to see if this light curtain beauty would disappear if the surrounding light source was cut off.

No, and nothing has changed.

The three of them had no choice but to ignore it, and together with this light, they entered the small second-floor villa.

Inside the villa, there is finally something interesting.

It's not the mahogany furniture common in the villa, it's not the wall-mounted TV, it's not the grand piano in the game hall of the singing room...... Nothing is not.

Inside this room, it's almost empty!

The field of vision is wide, and you can see all the two to three hundred square meters of space.

This is a space in the shape of a "hui".

There is a partitioned room in the middle, which is the middle part of the word "back". Around it, there are connected corridors. There was no furniture at all, and it looked empty. The interesting part is the four walls on the outside, each wall is about 15 meters long, and when connected, it is 60 meters.

Above is a large snake circling and connected.

The head of the snake bites the tail of the snake, forming a ring.

This snake with its head and tail on top ...... It looks familiar.

Suddenly, Xu Liang patted his head. Isn't this the big snake in the high school physics textbook that explains the size of the universe?

From the minus 10 to the power of the elementary particles, all the way to the cosmic scale of tens of billions of light-years, like a big snake biting its own tail, from the largest to the smallest, are connected.

Xu Liang wanted to take a closer look at the wall and found that the two scientist girls had already rushed over.

The two sisters looked at each other. It seems that a new continent has been discovered!

Duan Han (Qing): "This is a full set of tech trees!" ”

Duan Qing explained to Xu Liang: "This is the most comprehensive, all possible technology!" Whether it's researched or imagined, it's all included in the tech tree! ”

……

Taxonomy of science and technology:

Chapter xxx

Most people just know that technology is hard to learn.

Whether it's quantum physics that sounds very high, or it seems to be very low-end, the astrology used to fool ignorant girls. If you want to master it, then any science can consume a person's life (and cannot be exhausted).

So this creates a very interesting phenomenon: within each discipline, there is a very detailed classification. For example, biology has a relatively strict taxonomy - the plant kingdom, the animal kingdom, the microbial kingdom, and then continue to divide it; Chemistry is divided into organic chemistry, inorganic chemistry, and physical chemistry; Literature is divided into fictional literature and non-fiction literature, and fictional literature can be divided into prose and poetry...... In this way, it is difficult for a XX scientist, even if he is a true genius, to be a master in multiple fields at the same time. Like Leonardo da Vinci, Gu Yuxiu, Benjamin Franklin, and Tesla, there are few bulls who can surpass their predecessors in many fields, almost in the entire history of the world.

This has led to an interesting phenomenon: the classification within the discipline is very delicate and standardized. But the classification outside the discipline is confusing.

Has anyone ever categorized all of science?

Is there a standard tutorial like this?

Can you put physics, chemistry, and biomathematics into one category? Literature, linguistics, history, geography, political economy, in one category? If it is said that the college entrance examination is divided into arts and sciences, it is indeed possible, but classifying science according to the college entrance examination is quite ridiculous in itself.

There are many people in history who have tried to do this, hoping to build a real "all-tech tree"!

The knowledge of all mankind is transformed into a systematic tree diagram.

This kind of work has also produced some success, but it is difficult to get the recognition of mainstream academic circles: for example, the thinkers of ancient Greece classified science as a sub-discipline of "philosophy", for example, some thinkers in the Middle Ages divided all human knowledge systems into three categories: religion, physics, and stories; For example, some physicists believe that "all knowledge is physics......

In short, the overall generalization of the human knowledge system has been confusing.

One of the reasons is that with the development of the times, the development of science and technology is getting faster and faster, new scientific disciplines are constantly being created, and old disciplines are also dying out. It is difficult for a single individual to process so much information.

For example, the super-gate category of "communication technology", which was founded by Shannon in the middle of the last century, did not begin to flourish until the seventies and eighties of the last century, and has now become a fundamental discipline and the object of the work of countless scientific researchers. is one of the most thriving disciplines today.

It is an emerging discipline, and then cross-integrates with the old disciplines of the past, such as communication cryptography, communication transmission, and communication statistics...... It's just too many to count, and there's no way to talk about it.

Therefore, this has led to an interesting fact: although human science and technology are developing vigorously, the whole system of science and technology is chaotic and disorderly.

Not even a treemap.

It's just a big ball of thread mixed together.

Messy.

Mess.

At present, no one can claim to be able to understand all the knowledge in the field of "communication technology" and integrate it.

Not to mention the entire spectrum of knowledge.

Therefore, the classification of the overall human knowledge system is very confusing.

If Leonardo da Vinci 500 years ago could be said to be a person who knew more than half of the world's knowledge at that time, then the times have developed to this day, and no one dares to say that he knows one-ten-thousandth of the world's knowledge.

It is precisely because of the above. When Sister Duanqing and Duanhan saw this world-devouring snake on the wall, it was difficult to control their emotions. They found that the snake had been sorted and integrated into a "full tech tree".

"This is our conjecture about the 'full set of technology classification', but I didn't expect it to be made out by others." Duan Qing explained.

"It's easy to say, it's a way to categorize science by 'size.'"

"In this way, science can be classified!"

According to Duan Qing, the so-called science is the study of something. And everything, there is a range of sizes up and down. Each discipline has its specific object of study.

Biology, for example, is the study of objects the size of bacteria to objects the size of dinosaurs. What is this range? It is about 10^-6m~10^2m.

For example, quantum mechanics studies objects at the elementary particle scale, which is about 10^-15m~10^-31m.

For example, chemistry studies objects at the molecular level, and this range is about 10^-10m~10^-5m.

Wait a minute......

That is, it is classified according to the size of the volume of the object of study in the discipline.

Duan Qing: "It's, but it's not completely unreasonable. But, let's say...... Literature, how to classify? ”

"Actually, there is a way. This categorization sees 'literature' as a collection of processes in which the human brain changes emotions in response to information that is "encoded into words." In other words, this taxonomy treats 'literature' as a pure science and engineering, explained by biology, neuroscience, computational science, behavior, cognitive science, etc. The three elements of characters, plots, scenes, and story composition, bridge design, and other literary concepts have been completely abandoned, and literature and human beings are completely studied as an object. Therefore, in this taxonomy, literature is presented as an interdisciplinary discipline, and it belongs to the order of 10^1m. ”

"In this taxonomy, we use quantitative analysis instead of a lot of vague and unpractical analysis in literature."

"Let's look at architecture. It's easy to classify according to the scale, and this is not to be talked about. We can also break down this discipline into mechanics, materials science, aesthetics, etc...... The sub-disciplines of philosophy, such as aesthetics, are also studied in accordance with the above-mentioned methods of studying literature. ”

"Another example is economics...... Well, economics is the simplest, you just remember that all economists' predictions are wrong. ”

"Information science, for example, is actually a derivative discipline based on the second law of thermodynamics......"

"There are many, many disciplines that can find a place on this big snake!"

Duanqing connected the terminal that came with it in an unknown way to this big snake. Immediately after, the serpent seemed to be activated, and some parts of it had already emitted light.

It was lit up. Like a backlight, like a star in the night sky. The veins on it gradually became clearer.

Look little by little from the snake's tail to the snake's head.

The tail of the snake is the category of quantum mechanics, then condensed matter physics, then chemistry, then molecular biology, mechanics of materials, nanotechnology, etc.

Starting from the tail of the snake and gradually moving to the middle of the snake, it is getting bigger and bigger, and it covers more and more disciplines. In the end, in the range of 10^-1~10^3, the number of disciplines reached the maximum! It includes various genres such as systems science, chaos science, political science, missile science, publishing, biology, and engraving, and it can be said that the vast majority of human knowledge is concentrated in this part. But on the serpent's huge body, this interval is only an extremely inconspicuous part.

Further up, the snake's body was much more empty and much darker. It is the territory of aerospace science, telescopy, rocket mechanics, geophysics, evolutionary chemistry and other disciplines.

Finally, when the scale expands again, to the cosmic scale, there is only one discipline left - general relativity.

"You see, it's like a ring. The head of the snake is the general theory of relativity of the discipline that represents the largest scale of the universe, and the smallest scale is quantum mechanics, and the head of the snake bites the tail of the snake, both of which are physics...... Isn't it a coincidence......"

"As for the specific use of this snake for our current use, we can actually draw some conclusions."

"Our goal is to light up this snake as a whole!"

The whole snake, from the scale of 10^-35m, all the way to 10^28m, represents the scientific study of all scales. Human beings still know a lot about the scale of 0.1 meters ~ 100 meters, but the research on other scales is very rare.

The whole thing is a long snake, mostly dull and dull.

"We are still far from the goal of developing a full set of science and technology trees."

"If we can light up the entire big snake, it also means that our technology has developed to the pinnacle of this universe!"

"As for now, the level of technological development we have ...... It is at about 0.29%. ”

0.29 percent, that is, it is necessary to study 300 times the scientific and technological achievements at this stage in order to successfully reach the level of lighting up the entire universe. This is an ambitious goal. At this stage, the development of human science and technology has actually taken many detours, such as the development of religion and theology for thousands of years. It is not until modern times that the method of continuous iterative development of oneself has been established in a falsifiable way under the guidance of mathematical ideas that "gradually approximate the truth".

In this large amount of time, the study of science and technology such as astrology belongs to the discipline that has taken the wrong path and has made little contribution to subsequent development.

Of course, our strength also lies in the full set of technology! There is a little bit of everything! Even if science and technology cover the thinnest large-scale, there is also a relatively approximate theory such as general relativity, which can be reluctantly studied.

It's just that there are still a lot of things that need to be supplemented and improved.

"The snake of cosmic technology must be completely lit up!"

"I'll interrupt." Xu Liang said, "What are the specific benefits for us to light up a full set of technology trees? ”

Duan Qing: "There are many specific benefits, such as ......"
