What are the inspirations brought by nature?

Colorful butterflies, such as butterflies with double moon patterns, monarch butterflies with brown veins, especially butterflies with fluorescent wings, suddenly turn into gold, green and blue in the sun. Scientists have brought great benefits to military defense by studying the color of butterflies. During World War II, the Germans surrounded Leningrad in an attempt to destroy its military targets and other defense facilities with bombers.

Schwarzenegger, an entomologist in the Soviet Union, put forward the principle that the color of butterflies is not easy to be found in flowers, and covered military facilities with butterfly-like camouflage. Therefore, despite the German efforts, the military base in Leningrad remained intact, which laid a solid foundation for winning the final victory.

According to the same principle, people later produced camouflage uniforms, which greatly reduced the casualties in the battle. The constant change of satellite position in space will cause a sudden change of temperature, sometimes the temperature difference can be as high as two or three hundred degrees, which seriously affects the normal work of many instruments.

Inspired by the fact that scales on butterflies automatically change their angles with the direction of sunlight to adjust their body temperature, scientists made the satellite's temperature control system into a louver style with different radiation and heat dissipation capabilities, and installed a temperature-sensitive metal wire at the rotating position of each window.

The opening and closing of the window can be adjusted with the change of temperature, so as to keep the internal temperature of the satellite constant and solve a major problem in the aerospace industry.

Nature evaluates man and nature;

Nature gave birth to human beings, which shows that it respects human behavior. On the contrary, human beings should respect nature more. On the surface, people are born of their parents. In fact, only when nature has the photon information of human beings can human embryos absorb this photon information from nature and grow into adults, that is, parents. At the same time, nature has completed the excitation of dark matter in embryos.

There are 45336 species of vertebrates in nature, including birds 1244 species and fish 3862 species. There are more than 3 million species of insects, and only 1 10,000 species have been confirmed. Nature is a kind of natural resources, so people and nature should respect each other, keep the attitude of cherishing and caring, make proper use of nature and prevent it from being destroyed, so that the living environment is beautiful and the natural resources are inexhaustible, just like the intimacy and harmony between mother and child!

Therefore, the richness of information about nature can only be described as vast, and its complexity is not described by 30 thousand words or a few people.
