The Wandering Planet

The Central Academy of Sciences immediately conducted a comprehensive analysis and research on this black obelisk. Although the language on it is not any existing human language, it has many similarities with hieroglyphics in terms of structural logic.

Many linguists have pointed out that it feels like interpreting classical Chinese. A short sentence contains a huge amount of information, but the final interpretation is still a poem full of artistic sense, so it is essentially a piece of history. cultural relics.

The most specific information is only human biological information, so specific that a human embryo can be cultivated based on the data.

But when this obelisk fell on the earth, it was still at the beginning of life, and human beings would not appear until three billion years later. How did this obelisk record human biological information?

All of this makes people feel unbelievable. Where did this black obelisk come from?

To be honest, the moment he saw this obelisk, Qiao Lv had roughly guessed the origin of this cultural relic. There is no doubt that it is the human cultural relic in the collection of Li Bai Wenming mentioned by the system administrator.

As for how it ended up on the earth, it may be a good thing done by the system, just like the wandering earth's crossing.

But after the spiritual world came back, the system stopped responding, as if it had completely disappeared.

So Qiao Lv had no way of knowing how to interpret this black obelisk, and just knowing its origin was of no use.

Scientists are naturally full of interest in this black obelisk. Among other things, the ratio of the three sides of the obelisk is absolutely precise 1:3:9. up.

Ding Yi is of course very enthusiastic about it. He knows how difficult the so-called absolute precision is, so he knows that this is not an ordinary cultural relic, and its technological content is not as simple as a stone.

The material of the obelisk is also surprising. Generally, no matter what is buried in the ground for billions of years, it has long been eroded into disrepair, and the words engraved on it should also be smoothed.

But not only the words on this black obelisk are still clearly visible, but even the proportions of the three sides are kept absolutely accurate. This kind of technology is daunting.

Such a seemingly ordinary stone tablet contains unimaginable craftsmanship, of course Ding Yi will not let it go easily.

Li Yiyi, Ding Yi's student and assistant, also helped with various tests.

He was not so enthusiastic about this obelisk, thinking that this is what archaeologists should do.

The biggest focus right now is the ratio of the three sides of the black obelisk. Why did it take so much effort to make it absolutely precise 1:3:9?

In general, things that require absolute precision have special meanings. For example, the international kilogram prototype uses a cylindrical weight made of platinum-iridium alloy to define the standard weight of one kilogram. Even if it is only a few micrograms less, it can no longer be regarded as the standard.

So what is the purpose of maintaining such precision in the ratio of the three sides of this black obelisk?

"Could it be the golden ratio in art? For example, a golden rectangle or something." Li Yiyi asked.

There is indeed a saying of the golden ratio in art, specifically the irrational number of (√5-1)/2, which can be approximately equal to 0.618:1, just like pi generally takes 3.14.

This ratio is considered the most aesthetically pleasing and is used extensively in art. A rectangle with a ratio of 0.618:1 is known as the golden rectangle, and many architects design according to this ratio.

Considering that the front of this black obelisk is also a rectangle, and the poems full of artistic sense are engraved on it, it is natural to think of the golden ratio.

After all, 0.618:1 is just the golden ratio of human civilization. No one can say whether the golden ratio of an alien civilization will be 1:3:9. It is difficult to say about aesthetics.

Ding Yi shook her head and said, "Then do you know how the golden ratio came about?"

"Golden section, divide a line segment into two parts, so that the ratio of one part to the total length is equal to the ratio of the other part to this part. The ratio is the same as its reciprocal. The reciprocal of 1.618 is 0.618, and 1.618: 1 and 1 :0.618 is the same."

Li Yiyi's basic knowledge is still very solid, of course, this question will not trouble him.

Ding Yi lectured: "So for you, learning without thinking is useless. Since you know that the golden ratio is related to mathematics, why do you think it's just an aesthetic problem?"

Although the golden ratio is commonly used in art, it is still a mathematical method at its root.

Its appearance solves many mathematical problems, such as dividing a circle into ten equal parts, dividing a circle into five equal parts, finding the sine and cosine of 18 degrees and 36 degrees, etc. It is by no means a purely aesthetic problem.

"The so-called beauty must follow certain rules, and art and mathematics are inseparable. Otherwise, why does everyone who learns to paint have to learn geometry? Don't you even understand this?"

Li Yiyi was taught by Ding Yi so much that he couldn't hold his head up. He still thought things too easily.

"Then teacher, do you think that this obelisk is made in such a precise proportion to convey some kind of information?" Li Yiyi asked.

Ding Yi raised her head and said: "The most direct guess is that it wants to tell us that the ratio of something is 1:3:9. It may be some kind of formula, which means too much."

For example, from decaying uranium to fission atomic bombs, to the nuclear fusion of the sun, to the annihilation of matter and antimatter, all follow a short formula: E=mc2.

If this is indeed some kind of formula, its effect may be unimaginable. Just as the golden ratio above has many uses in mathematics, a simple ratio has the potential to change everything.

At this time, the linguists responsible for interpreting the poems on the obelisk also made a major discovery, that is, whenever numbers are involved, the poems use the decimal system.

Don't take it for granted that the universal use of decimals is simply a consequence of the biological fact that the vast majority of people are born with 10 fingers.

Just as children often start learning mathematics by counting their fingers, the first mathematics is born in this way. In fact, among the written numbering systems independently developed in the ancient world, except for the cuneiform numerals of the Babylonian civilization, which are base 60, and the Mayan numerals, which are base 20, almost all of them are decimal.

Humans take it for granted, but this is not the case for alien civilizations. If an alien race has 8 fingers, it is more likely to be inclined to octal, and it will be uncomfortable with decimal.

This point has also been confirmed long ago. The Cybertron civilization directly uses binary, the Trisolaran civilization generally uses hexadecimal, and the singer civilization is an outrageous thirty-hexadecimal system. It is possible that what grows with them is not fingers but tentacles. related.

Therefore, the decimal system cannot be taken for granted. Combining the human biological information recorded on the obelisk, and of course including the key point of having ten fingers, other people have gradually approached the truth behind this black obelisk.
