In this chapter on the language of nature, I will list all the scientific knowledge used in this book.

"Baidu People" Chapter 0003: Half a face under the moonlight

The origin of the fire pattern of the Big Dipper Array mentioned in the article mainly refers to the fact that the fire has the characteristics of heating and upward, because the hot air generated by the fire is very hot, slowly rising, so that the surrounding air slowly moves closer to the fire, so that the surrounding fire will move closer together with the rising air traction, so as to connect the city. (For example, on the grassland, you must not run along the direction of the wind)

Chapter 0011 of "Baidu People": Curly-haired wild monkey

The curly-haired wild monkey mentioned in the article eventually threw away Xiao Jiezi's shoulder bag, because the monkey is a close relative of humans, and all of them belong to the primate order in terms of animal classification. It has a developed brain that is different from that of ordinary animals, and its degree of evolution is relatively close to that of a human brain, and the structure of the monkey's brain is complex and perfect, and the surface is covered with solid lines.

The more fixed lines there are in the brain, the more complex the behavior, the stronger the memory and thinking skills, and the more mimicry they have. The weight of the human brain is 2% of the whole body, and the weight of the monkey brain is 1.6% of the body weight, which also shows that the monkey is the closest to a human and is a very intelligent animal.

In addition, monkeys have longer hind limbs than their forelimbs and are able to walk upright, and the thumb of the five fingers is longer than the other four fingers and can face the other limbs. All this also provided the rational conditions for him to imitate human movements.

Chapter 0015 of "Baidu People": The mutated dragon's blood tree

The closed natural rock caves mentioned in the article mainly use the principle of air pressure. The water keeps flowing into this enclosed pool, why is it just dissatisfied?

In fact, the natural cave has a hole, as long as there is a strong wind blowing on the mouth of the natural cave, it will make a small whirlpool appear in the waterhole in the natural cave, which shows that there must be a hole in the pool that seems to be a pool of stagnant water and the outside is connected, as long as the wind outside the cave mouth will make the air pressure of the outside hole drop, and the water inside will naturally be pressed out along the hole at the bottom of the pool.

Chapter 0024 of "Baidu People": Break the door hand in hand

The stone door that opens from the inside out in the article, the surface is as smooth as a mirror, how to open it? The principle is very simple, mainly using the force of suction and air pressure.

The burning of the confetti causes the air in the basin to be heated and expanded, causing the density of the inside to decrease, and at this time, it is closed off from the outside atmosphere by turning it upside down on the stone door covered with wet calligraphy and paintings. When the flame in the basin is extinguished, the temperature decreases, the hot air will contract, and the air pressure in the basin will be lower than the atmospheric pressure, and the pressure difference between the two can firmly suck the stone door up.

As for why the golden basin does not fall and has a lot of suction? The key to this is mainly the sealing effect of wet calligraphy and painting, if the basin is ignited and then "hard to touch" upside down on the stone door, even if the bottom of the stone door of the basin mouth is smooth, it is difficult to seal the interface. If the calligraphy and painting are not soaked, the air can still pass through the gaps in the paper. When the water fills the micropores in the calligraphy and painting, the contact part between the wet calligraphy and the basin becomes an "O-ring", which effectively prevents gas leakage and ensures the existence of pressure difference between the basin and the atmosphere.

"Baidu People" Chapter 0025: Strange Figurines

The article mentions the way to deal with vampire bats, in fact, vampire bats belong to the kind of highly myopic eyes, extremely poor vision, and basically can't see things.

When they attack the enemy, they mainly rely on the ultrasonic waves emitted, using the echo to locate to determine the direction of the prey, as long as we quickly turn the trouser belt in our hands, forming a strong wave to bounce off the ultrasonic waves they emit, then they will actively collide with themselves.
