The wings of flies (also called balance bars) are "natural navigators", and people imitate them to make "vibrating gyroscopes". At present, this instrument has been applied to rockets and high-speed aircraft, realizing automatic driving.
The fly eye is a kind of "compound eye", which consists of more than 30O0 small eyes. People imitate it and make a "fly-eye lens". The "compound eye lens" is composed of hundreds or thousands of small lenses arranged in sequence. It can be used as a lens to make a "compound eye camera" and can take thousands of identical photos at a time. This kind of camera has been used for printing plate making and copying a large number of tiny circuits of electronic computers, which greatly improves the work efficiency and quality. "Compound eye lens" is a new type of optical element, which has many uses.
Birds' wings have many special functions and structures, which make them not only good at flying, but also perform many "stunts" that are difficult for human technology to achieve at present. Hummingbird is a "helicopter" among birds. It can take off and land vertically and fly backwards. When sucking nectar, it does not stop on the flower like a bee, but hovers in the air. What a clever flight this is. It has become the dream of many aircraft designers to make vertical take-off and landing aircraft with hummingbird flight characteristics.
Inspired by penguins, people designed a new type of car "Penguin Polar Off-road Vehicle". This kind of car is stuck on the snow surface with wide bottom and pushed forward with a wheel spoon, which not only solves the polar transportation problem, but also can drive in muddy areas.
Fly eye invented the fly eye camera.
The sensitive perception of flies led to the invention of hazard detectors, which were used in dangerous workplaces.
The gliding skill of the eagle invented the glider.
The shape of the bird's thread has changed the appearance of the plane and is more aerodynamic.
The bones of birds have improved the skeleton structure of aircraft, making it lighter and stronger.
Acoustic detection of bats and dolphins invented ultrasonic radar.
What people get from bats is that airplanes fly by radar at night.
Cactus, ants, these natural things can be seen everywhere, so it is not unusual, but don't underestimate them.
Have you ever seen a group of small ants crawling on the wall? They always carry food as small as sand and walk in groups. That tiny figure's life is very weak. As long as it is pressed by people, its life may end like this. Although ants are small, they are very United. When an ant finds food, because the food is too big for him to carry, he immediately returns to his nest and informs his partner that everyone can unite and succeed. We are the same, if we can't unite, we are like a loose sand, with no strength at all; If we can cooperate, we can stand firm in life.
Cactus live in desert areas, where the heat is unbearable and there are many ferocious beasts. The situation is very dangerous. But the cactus lived there for a long time, but it didn't go extinct. This is because it grows sharp thorns to adapt to the dangerous environment, which makes animals helpless. This seems to tell us that we must rely on our own strong perseverance to overcome difficulties and solve the external difficult environment. As the saying goes, "Nothing is difficult in the world, only if you put your mind to it." "This is a fact.
In nature, it inspires us too much. As long as we understand them with our heart, we can have a deeper understanding of life. Aren't cactus and ants good examples? Respondent: hujinhui 12 | Level 1 | 2009-3-210: 45.
abstract
About nature-water, air, mountains, rivers, microorganisms, plants, animals, the earth, the universe and so on. , all belong to the category of nature; The science of studying nature is natural science, including mathematics, physics, chemistry, biology, geography and other sciences, and the branches of these sciences are very complicated, such as: biological science can be divided into microbiology, botany and zoology; Then it can be divided into molecular biology, cytology, genetics, physiology and so on. The intersection of various disciplines will produce many branches, such as biochemistry, biophysics, molecular structure biology and so on.
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, maintain the attitude of cherishing and caring, make proper use of nature and prevent its destruction, so that the living environment is beautiful and the natural resources are inexhaustible, just like the mother and son are close and harmonious.
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.
Natural classification
There are all kinds of creatures in nature, including plants, animals, bacteria and fungi. At the same time, nature is also a place containing various ecosystems!
The elements of nature are divided into light, darkness, water, fire, wind, thunder and earth, which means that nature controls the balance of these things.
The influence of nature on the spirit is the first in time and the most important in place. Every day, the sun; After sunset, at night, with her stars. The wind has been blowing; Grass grows forever. Every day, men and women are talking, watching and being watched. Of all people, that image attracts philosophers the most. He must decide its value in his own mind. What is nature in his eyes? This web of God, its incomprehensible coherence, has never started or ended. It is always a circulating force, returning to itself. This is similar to his own mind, and he will never find its beginning and end-so complete and infinite. The glory of nature has been shining so far. There is a universe above the universe, which radiates like light, upward and downward, without center and circumference-whether it is gathering or dispersing, nature is eager to express itself to people's hearts.
It's beginning to be classified. In the minds of young people, everything is individual, standing there alone. Gradually, he knows how to connect two things and see the same sex between them; Then three things, then 3000 yuan; So he was dominated by his instinct to unite everything, continued to tie things together, reduced irregularities, found underground roots, linked opposing and distant things, and blossomed on the same branch.
He soon learned that since the beginning of history, facts have been continuously collected and classified. But what is the meaning of "classification"? It is nothing more than seeing that these things are not chaotic and have nothing to do with each other, but have certain laws, which are also the laws of the human mind. Geometry is purely abstract in human mind. Astronomers find that the motion of planets can be measured by geometry. Chemists found that all substances have proportions and understandable laws; What is science? Nothing more than looking for similarities and similarities in the farthest things. An ambitious person sits down to study every uncontrollable fact; Put all the strange structures and all the new forces into their categories one by one. Induce it into their theorem, and go on like this forever, and give life to the last fiber of various organizations and the outer edge of nature with profound observation.
Therefore, the students under this sky feel that he and nature are "born from the same root"; One is a leaf, the other is a flower; Friendship and sympathy are everywhere.
What is a root? Not the soul of his soul? An overly bold idea; An absurd dream. However, once the glory of the soul helps him discover the laws of physical properties-when he knows how to worship the soul and sees that the existing natural philosophy is only the preliminary exploration of the soul master, then he will look forward to expanding his knowledge and becoming the creator of the future. He will see that nature is the opposite of the soul, and every part echoes it. One is a stamp, and the other is printed text. Its beauty is the beauty of his own heart. Its law is the law of his own mind. So he regards nature as the standard to measure his achievements.
He doesn't know enough about nature, that is, he doesn't know enough about his own mind. In a word, the old proverb "know yourself" and the modern proverb "study nature" finally became the same motto.

Fish have the ability to come and go freely in the water, so people imitate the shape of fish to build ships and use wooden paddles to imitate fins. According to legend, as early as the Dayu period, the working people in ancient China observed fish swimming and turning with their tails wagging in the water, so they put wooden paddles on the stern. Through repeated observation, imitation and practice, it was gradually changed to paddle rudder, which increased the power of the ship and mastered the means of capsizing. In this way, even in the rolling river, people can let ships sail freely.
The wings of flies (also called balance bars) are "natural navigators", and people imitate them to make "vibrating gyroscopes". At present, this instrument has been applied to rockets and high-speed aircraft, realizing automatic driving. Respondent: Baidu knows _ | Level 1 | 2009-3-2121:41.
Modern radar-a radio positioning and ranging device: Scientists have found that bats rely not on eyes, but on an echo positioning system consisting of mouth, throat and ears. Because bats emit ultrasonic waves when flying, they can also detect ultrasonic waves reflected by obstacles. Based on this, scientists have designed a modern radar-a radio positioning and ranging device.
By studying the tiny swimming resistance of dolphins, scientists invented artificial dolphin skin which can improve the speed of torpedoes. And a wheeled vehicle (jumping machine) that imitates kangaroo's movement in the desert.
Inspired by penguins, scientists from the Institute of Zoology of the former Soviet Academy of Sciences designed a new type of car-Penguin brand polar off-road vehicle. The wide bottom of this car is directly attached to the snow surface and supported by a wheel spoon, and the driving speed can reach 50 km/h.
Scientists make space robots by imitating insects. A research team of Australian National University has developed a small navigation and flight control device by studying several insects. This device can be used to equip small aircraft for Mars exploration.
Inspired by bionics, British scientists are developing a new submarine, which can swim in an S shape by swinging its tail fin. The main innovation is the use of a device called "trunk actuator". "Elephant trunk" consists of a group of thin and soft hoses, which imitate muscle activity and promote fin movement. This new submarine can be used as an underwater mine-clearing submarine to deal with mines that will detonate at the slightest sound or interference.

The ancients had an extremely profound saying: Learn from nature. Great! Nature has indeed taught us many, many lessons, and each lesson is more exciting than the next. Listen to three stories first.
One of the stories: AB was originally two unrelated trees. Because it is closely intertwined with the ivy, it grows together unconsciously. From growing together, a tree bears a brand-new fruit, which is still a in shape but tastes like b, look! How wonderful nature is. With such inspiration, gardeners suddenly realized that they had learned to graft in one fell swoop.
Story 2: In order to dry clothes, someone tied wire to two trees not far apart. Over time, the iron wire formed an iron hoop and was firmly pulled into the trunk, leaving a deep impression on the tree. Two years later, the hoop was deeply pulled into the tree. The poor tree seemed to be dying, but a miracle happened. The tree didn't strangle, but stood up firmly and swallowed the terrible iron hoop alive! And all this happened to be seen by a desperate old man, and he summoned up the courage to live. The old man has cancer! He overcame his illness and survived. After living for several years, his last words when he died were: Thank you for that tree! Look! How profound nature is, although silent, it can give people extraordinary power.
Story 3: Do you know the origin of pearls? Although they are as magnificent as stars, their origin is like a very terrible and long dream. Since a stone suddenly fell into the tender body of a pearl shell, this terrible nightmare began! The rough stone tormented it day and night, stinging it, but it was so strong that it not only accepted the sudden pain, but also resolutely bit it, silently, silently, year after year, until it became a bright pearl. This is a soul-stirring lesson! Does nature tell us in its unique way, such as the meaning of suffering? This is a sacred sport. Yes, there are many similar stories. Mature ears of wheat droop their heads, which is teaching us humility. A group of ants can carry big bones, which is teaching us unity. Gentle water drops can pass through rocks, which teaches us tenacity. Bees are busy shuttling among flowers, which teaches us to work hard. The poor grass silently closed the leaves, which told us not to overstretch the fields. Yes, nature is the best teacher. As long as we are willing to study, we will gain something every day.
Cactus, ants, these natural things can be seen everywhere, so it is not unusual, but don't underestimate them.
Have you ever seen a group of tiny ants crawling on the wall, always carrying food as small as sand and walking around in groups? That tiny figure is very fragile. As long as it is crushed, its life may end like this. Although ants are small, they are very United. When an ant finds food, it is too big to carry it by itself, so it immediately returns to its nest and informs its partners that everyone can unite. If we can cooperate, we can stand firm in life.
