Chapter 717: Golden Ratio and Decimal

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

Many linguists have pointed out that it feels like they are reading classical Chinese. Short sentences contain a huge amount of information, but the final interpretation is still artistic poetry, so it is essentially a history. Cultural relics.

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

But when the obelisk landed on the earth, it was still the beginning of life, and humans only appeared after three billion years. How does this obelisk record human biological information?

All of this makes people feel unbelievable, where did this black obelisk come from?

To tell the truth, at the moment when he saw this obelisk, Qiao Lu had probably guessed the origin of this cultural relic. It is undoubtedly the one mentioned by the system administrator, which is a human relic collected by Li Baiming.

As for how it finally came to earth, it may be a good thing the system does, just like the wandering of the earth.

But after the spiritual world came back, the system no longer responded, as if it had completely disappeared.

So Qiao Lu could not know how to interpret this black obelisk, but it was not very useful to only know the origin.

Scientists are naturally full of interest in this black obelisk, let alone say, the ratio of the three sides of the obelisk is absolutely accurate 1: 3: 9, this has been imaginative, let alone the meaning of the above poems Too.

Ding Yi is of course very enthusiastic about it. He knows how difficult it is to call absolute accuracy, 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 already been eroded to the point that it should be flattened.

However, not only the words on the black obelisk are clearly visible, but even the proportion of the three sides is kept absolutely accurate. Such a technique is daunting.

This seemingly ordinary piece of stone contains an unimaginable ghost and axe, and of course Ding Yi will not let it go easily.

Li Yiyi, a student and assistant of Ding Yi, also helped with various tests. He was not so enthusiastic about the obelisk, thinking it was the archaeologist's job.

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

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

So what is the reason for maintaining the accuracy of the three sides of this black obelisk?

"Will it be the golden ratio in art? For example, the golden rectangle or something." Li Yiyi said.

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

This ratio is considered to be the most aesthetic, so it is widely used in art. A rectangle with a ratio of 0.618: 1 on both sides will be called a golden rectangle, and many architects will design according to this ratio.

Considering that the front of this black obelisk is also a rectangle, and it is engraved with artistic poetry, it is a matter of course 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 such a thing as aesthetics.

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

"Golden section, divide a line segment into two parts so that the ratio of one part to the full 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 problem can not help him.

Ding Yi taught: "So you, you just learn without thinking. If you all know that the golden ratio is related to mathematics, how do you think this is just an aesthetic problem?"

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

Appeared to solve many mathematical problems, such as tenths, fiveths of a circle, finding the sine and cosine values ​​of 18 degrees and 36 degrees, etc. It is by no means a pure aesthetic problem.

"The so-called beauty must follow a certain rule, art and mathematics are inseparable. Otherwise, why everyone who learns painting must learn geometry, don't you even understand this?"

Li Yiyi was too upset by Ding Yi's lesson, he still carelessly thought things too simple.

"So teacher, do you think that this obelisk is to make the proportion so precise to convey some kind of information?" Li Yiyi asked.

Ding Yi looked up and said: "The most direct guess is that it wants to tell us that the ratio of certain things is 1: 3: 9, which may be some formula, which means too much."

For example, from decayed 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 really a formula, its effect may be too large to imagine. Just as the golden ratio mentioned above has multiple uses in mathematics, simple ratios can also be an opportunity to change everything.

At this time, the linguist responsible for interpreting the poetry on the obelisk also made a major discovery ~ EbookFREE.me ~ That is, whenever numbers are involved, the poetry uses decimal numbers.

Do not take it for granted. Humans generally use the decimal system, but most people are born with 10 fingers, the result of such a biological fact.

Just as children tend to learn mathematics by counting their fingers, the original mathematics was born in this way. In fact, in the written system of numbers independently developed in the ancient world, except for the Wedge-shaped numbers of Babylonian civilization are 60 hexadecimal and Maya numbers are 20 hexadecimal, almost all are decimal.

Human beings 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 prefer octal, but it will not be used to decimal.

This has long been confirmed. Cybernetic civilization directly uses binary, tri-body civilization generally uses eleven, and singer civilization is outrageously hexadecimal. It may be that they grow not with fingers but with tentacles. related.

Therefore, we cannot think that the decimal system is justified. Combining the human biological information recorded on the obelisk, of course, including the ten fingers, others began to gradually approach the truth behind the black obelisk.
