This huge "rock" has been cleared away bit by bit, and it is only the part that is currently exposed. Compared to the ants, it is like a small mountain.
At the beginning of the excavation project, the protagonist cannot see the whole picture clearly. He can only see that it is roughly an irregular elliptical sphere.
What attracted him most was the countless symbols on it. These symbols were composed of various straight lines, curves, points, etc., and the traces of artificiality were obvious. This could never be a miracle of nature's miraculous craftsmanship.
Among them, there are many graphic symbols that the protagonist does not recognize. But there were many, although there were no language annotations, or they did not use the numbers and letters annotation symbols he knew, but their characteristics were very obvious, making him familiar with them after nine years of compulsory education, and he could recognize them at a glance. .
In addition to the Pythagorean theorem, there is a figure that is a double helix curve with many short horizontal lines connecting the hyperbolas. This clearly symbolizes the double helix structure of DNA!
The double helix structure is a common basic unit in biological structures. The significance of the double helix model not only means that the structure of the DNA molecule has been discovered, but more importantly, it also hints at the replication mechanism of DNA, which shows that the bases of the two strands The sequences are complementary to each other. As long as the base sequence of one strand is determined, the base sequence of the other strand will also be determined. Therefore, you only need to use one chain as a template to synthesize and copy the other chain. The double helix structure shows that DNA molecules can replicate themselves during cell division, which perfectly explains the mechanism by which living organisms reproduce, species remain stable, and cells possess genetic attributes and replication capabilities. The discovery of the double helix structure is a milestone in biology, the beginning of the era of molecular biology, and the foundation of genetic science.
Another example is this, a hexagonal structure. Some of the hexagonal vertices have short straight lines extending outward, and some short straight lines are inside the hexagon, parallel to the sides of the hexagon. If the protagonist remembers correctly, this is the structural formula of a benzene ring.
The benzene ring is the structure of the benzene molecule. The structural formula is a regular hexagon. Each vertex is a carbon atom, and each carbon atom is combined with a hydrogen atom. The carbon-carbon bonds in the benzene ring are unique bonds between single bonds and double bonds, and the bond angles are all 120 degrees.
The hexagonal structural formula of the benzene ring is very classic. It was proposed by the German chemist Kekule in 1865. He proposed an idea for the structure of benzene, that is, the carbon chains may be connected head to tail to form a ring. According to Kekule's own writings, he was inspired by a dream in which he saw a snake connected head to tail. Kekulé's structural formula was the most satisfactory of the many "benzene ring structures" at that time, and it successfully explained many experimental facts.
Next to the benzene ring, there is another larger figure, consisting of a bunch of small squares forming an irregular rectangle with a concave top. You can tell at a glance that this table is a periodic table of chemical elements, even though the symbols in the small squares are not the Arabic numerals and 26 English letters that the protagonist is familiar with.
The periodic table of chemical elements is a list of chemical elements ordered from smallest to largest atomic number. The list is generally rectangular, with spaces left in some element cycles so that elements with similar properties can be grouped into the same group, such as alkali metal elements, alkaline earth metals, halogen elements, rare gases, etc. This makes the elements in the periodic table divided into seven main groups, seven sub-groups, Group VIII and Group 0. Because the periodic table accurately predicts the properties of various elements and their relationships, it is widely used in chemistry and other sciences as a useful framework for analyzing chemical behavior.
The periodic table of chemical elements was invented by Russian chemist Dmitri Mendeleev in 1869 and is known as the source code of the universe.
I remember that the protagonist read a science fiction novel when he was a child. It said that humans met aliens, but there was a language barrier between the two parties and they could not communicate. So he relied on the periodic table of chemical elements to start a step-by-step language translation. This periodic table of elements can also be said to be a universal language for the entire universe.
Another newly unearthed pattern. When the protagonist went over and took a look, it was a pattern that looked very much like an electron cloud. Perhaps it was an electron cloud pattern.
The electron cloud is a graph that uses the density of small black dots to represent the probability of the occurrence of electrons in space. Electrons move at high speed in a small space outside the nucleus. Their movement rules are different from those of ordinary objects. They have no clear orbit. According to the uncertainty principle in quantum mechanics, it is impossible for an observer to accurately measure the position and speed of an electron at a certain moment at the same time, nor can it describe its trajectory. Therefore, people often use a model that can represent the chances of electrons appearing everywhere in the extranuclear space within a certain period of time to describe the movement of electrons outside the nucleus. In this model, the density near a point represents the chance of an electron appearing there. Where the density is high, it means that there are more opportunities for electrons to appear within the unit volume of space outside the nucleus; on the contrary, it means that there are fewer opportunities for electrons to appear. Since this model resembles a layer of "cloud" of varying density outside the atomic nucleus, people vividly call it the "electron cloud". In 1926, the Austrian scholar Schrödinger made appropriate mathematical treatments for the motion of electrons based on the De Broglie relationship, and proposed the famous Schrödinger equation of second-order partial differential. The solution of this equation, if used in three dimensions If the coordinates are represented graphically, they are electron clouds.
At the excavation site on the other side, the protagonist saw a galaxy map—perhaps the solar system.
This galaxy diagram consists of a huge star and nine planets orbiting it. The fifth planet is particularly huge, the sixth planet has planetary rings, and there are countless dense dots between the fourth and fifth planets. It represents the asteroid belt, which is highly consistent with the solar system.
But the difference is that in the era where the protagonist lives, Pluto has been kicked out of the nine planets, and the solar system is considered to have only eight planets. In this galaxy map, the circle of the ninth planet is no smaller than Uranus and Neptune, and it absolutely cannot be Pluto, which is not as big as the moon.
But the protagonist firmly believes that this is the galaxy map of the solar system. On the one hand, it is because of a strong premonition, and on the other hand, it is impossible for two galaxies to be so similar. Moreover, the environment, climate, and species of the planet where the protagonist is now are also different from those in his previous life. The Earth is highly similar. It would be too much of a coincidence to say that the two are on different planets.
In addition, among the graphics that have been excavated one after another, there are many familiar to the protagonist, involving various natural science disciplines such as mathematics, biology, physics, chemistry, astronomy, etc.
And when the whole "rock" was finally revealed, the protagonist was shocked again...
