In ancient times, people saw fish swimming freely in the water, so they invented boats and paddles based on fish's breasts and fins. When people saw birds flying in the sky, they invented airplanes and realized their wish of "flying to the blue sky".
In the past, tanks had only one floor. If the enemy is on the right wing, it is necessary to airdrop the whole tank. People get inspiration from turtles. The tortoise can face in any direction on its back. Therefore, man invented the rotating gun.
I saw children playing with remote control boat and my friends playing with automatic planes, so I thought: remote control boat is propelled by propellers, and automatic planes are driven by springs, so automatic ships should be driven by springs. I went home and tried, and it worked, but I couldn't fly fast. I think dolphins have triangular tails. They swim very fast. I made the stick at the tail into a triangle, and it succeeded.
Nature has given us so much inspiration!
& lt2> Humans have found some things from dragonflies and whales, but there are inventions in flies that everyone hates!
Entomologists found that the back wings of flies degenerated into a pair of balance bars. When it flies, the balance bar vibrates mechanically at a certain frequency, which can adjust the movement direction of its wings. It is a navigator to keep the balance of flies. Based on this principle, scientists have developed a new generation of navigator-vibrating gyroscope, which greatly improves the flight performance LlJ of the aircraft, enables the aircraft to automatically stop the dangerous rollover flight, and automatically restore the balance when the body is strongly inclined, even when the aircraft is in the most complicated sharp turn.
The fly's compound eye contains 4000 single eyes that can be imaged independently, and almost 360 can be seen clearly. Objects within range. Inspired by the fly's eye, people made a fly's eye camera consisting of 1329 small lenses, which can take 1329 high-resolution photos at one time. It is widely used in military, medical, aviation and aerospace fields.
Flies have a particularly sensitive sense of smell and can quickly analyze dozens of smells and respond immediately. According to the structure of flies' olfactory organs, scientists have converted various chemical reactions into electric pulses, and made a very sensitive small gas analyzer, which is widely used in spacecraft, submarines, mines and other gas components, making the safety factor of scientific research and production more accurate and reliable. Nature is really a good teacher for human beings.
Nature has given mankind a lot of inspiration and is the earliest "teacher" of mankind. There are many strange things in nature, and animals and plants have their own unique characteristics.
For example, when the wind blows, dandelions fly in the blue sky, like some elves dressed in white. People invented parachutes through its characteristics of fluttering with the wind, so that when people jump in the air with parachutes, they won't get hurt.
Others were invented by animals. For example, horses run very fast, and humans will think: If only we could invent a machine that runs faster than horses. Time flies, with the continuous development of science and technology, human beings invented the car, which allows us to reach our destination quickly when traveling. People also invented airplanes by imitating the flight of birds. At that time, if we were going far away, it was not fast enough to take the bus. People look at birds flying in the sky and think, if only we could fly. Man invented the airplane again.
Human beings are smart, but if we don't have the nature of "teachers", we can't even think about it, let alone invent and create. It is precisely because of this "teacher" that human beings can boldly imagine and constantly invent and create.
Nature, the "teacher" of human beings, is precisely because of it that our life is no longer boring and ordinary, and our life has become full of imagination and colorful! Nature, you are the "teacher" of mankind. Pay attention to learning everywhere.
Early in the morning, I found a "gossip array"-spider web in my corner, and I had an idea: how do spiders hunt? Strong curiosity drove me to catch a small grasshopper and put it on a spider web.
At this time, the spider seemed to smell the attractive fragrance and climbed out from the crack in the wall. It spit out a white silk next to the grasshopper, wrapped it slowly, and swaggered back to the hole. I am puzzled: why do spiders go back to their holes and why don't they eat grasshoppers? I continued to observe. But after waiting for a long time, Uncle Spider just won't come out. I went home bored.
The next day, I came to the corner and was surprised to find that the spider had eaten the grasshopper, leaving only an empty shell on the Internet. I wonder why spiders don't eat shells. In order to find the answer, I read a lot of information and finally found the answer in "100,000 Why". It turns out that after a spider catches its prey, it must first wrap it with silk, and then spit out a digestive juice and inject it into its prey. This digestive juice can dissolve the internal tissues of insects composed of protein, and it will become juice after the insects die. Spiders can suck big mouthfuls. Because the shells of insects are not made of protein, the shells of grasshoppers remain intact on the net.
Through this unexpected discovery, I know the mystery of spiders eating. Although this is only a small discovery, it makes me understand a truth: pay attention to learning everywhere. Seemingly ordinary nature, in fact, there are endless mysteries waiting for us to explore and discover, so don't stick to the discovery of scientists.
