Enlightenment from an incident in life.

I am intoxicated with the beauty of nature, and I am amazed at everything in nature. I can see a harmonious family near a big tree.

I have never seen such a thick tree that I can't reach it. I looked up and saw the thick branches intertwined, crowded and stretched upward. A tree seems to be a family. All branches live in harmony. They touch and hug each other, like a warm family. Occasionally, they will have friction. When the wind comes, the branches beat each other and hurt each other. After the strong wind, they always hug and touch each other.

Every time I see a big tree, I always feel nostalgic. It turns out that friendship can make people happy and tolerant, like a big tree, which can open warm and broad arms. This seems to be the epitome of human society. We live in a crowd, sometimes we hate each other, sometimes we care about each other and help each other. In fact, we are also a family of trees, living in peace and friendship.

The revelation of nature

Wu

Nature is one of the "treasure houses" on our earth. Its contribution to mankind is obvious to all. Although it sometimes degenerates, when it is alive, we can fully appreciate the warmth it brings us. -Although a seed can do nothing, it is the origin of an oasis; Although a seed has no power, no one can imagine when its power reaches its limit; Although a seed is useless, when it grows up, it is the best helper to give us shade.

If every seed misses that tree and only hopes when it will rain in the sky, then all our cities and high-rise buildings will be swallowed up by the desert and flooded ... so, the seeds in the world will survive, and only through their own efforts will they survive in this world. On the contrary, if you don't work hard, it will be difficult to become a member of the shade, but its life will be short because it is lazy. On the contrary, the story also shows a spirit of self-reliance and perseverance, and finally achieves the result of his own efforts-becoming a tall and straight tree.

Like the course of these two completely different seeds, we can imagine that we should be like this in real life.

Everyone's journey is actually no different. The most important thing is whether you can grasp the results you have won, instead of just "sitting" there and slowly waiting for your own results.

Although it is also fruitful, losing it is another taste: because one is sweet and the other is bitter.

If I had to choose, I would definitely choose the former, because everyone who knew right from wrong at that time understood the truth.

Enlightenment of nature to human beings

Nature is beautiful, so we should protect it. We shouldn't throw rubbish, spit and cut down trees. Then, I will tell you a story.

Once upon a time, there was a village. He doesn't like to protect nature, so he cuts down trees and makes them into chairs and tables. Soon, everyone in the village felt that the house was old and should be replaced. People went to chop wood to build houses, and the houses were finished. People in the village there cried happily. Some people were very proud. Their houses were more beautiful than others. In this way, people cut down trees every day.

Soon the flood came and the village was completely destroyed by the flood. Even the most beautiful houses were washed away by the fierce flood, because some houses were washed away because of countless obstacles, and this place became a wasteland. This story is for everyone not to pick up the land indiscriminately.

Nature is so good, why would anyone want to destroy it? Let me talk! Because some people have nowhere to throw, they can't throw them underground. Some people think it's just a waste of garbage and no tutor. In our class, some people don't eat apples, but also draw pictures on them. Some people chew and spit on the ground, which makes life on duty very troublesome. In such a good environment, they learned to listen. The small bones of ants help us unite, while bees collect honey and teach us to work hard. Do you think nature is so beautiful that you are willing to destroy it?

The survival of human beings depends on nature, and the development of human beings is based on the revelation of nature. Without the revelation of nature, human beings would not be so developed now ... The revelation of nature to human beings is that nature is beautiful, so we should protect it and not throw garbage, spit or cut down trees.

The invention of mankind-inspired by animals-ships and submarines came from people's imitation of fish and dolphins. Scientists have made the first batch of gas masks in the world according to the unique drug detection ability of wild boar nose. The rocket takes off by using the recoil principle of jellyfish and squid. Researchers have developed many military camouflage equipment for the army by studying the chameleon's color-changing ability. Scientists studied frog eyes and invented electronic frog eyes. The US Air Force has developed a miniature thermal sensor through the "hot eye" function of poisonous snakes. Humans also used the principle of leapfrog to design a toad ram (hang). Humans imitate the highly sensitive sense of smell of police dogs and create "electronic police dogs" for investigation.

Bionic and high-tech modern radar, a radio positioning and ranging device: scientists found that bat monsters rely not on eyes, but on an echo positioning system consisting of mouth, throat and ears. Because bat magic emits ultrasonic waves when flying, it can also detect the ultrasonic waves reflected by obstacles. Based on this, scientists have designed a modern radar-a radio positioning and ranging device ... Scientists have invented an artificial dolphin skin that can improve the speed of torpedoes by studying the tiny swimming resistance of dolphins; And a wheeled vehicle (jumping machine) that imitates kangaroo's movement in the desert. Inspired by King Penguin, scientists from the Institute of Zoology of the former Soviet Academy of Sciences designed a new type of car-"King Penguin" brand polar off-road vehicle. The wide bottom of this car is directly attached to the snow surface, supported by a wheel spoon, and the 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.

According to the visual principle of frog eye, people have successfully developed an electronic frog eye. This kind of electronic frog's eyes can accurately identify objects with specific shapes like real frog's eyes. After installing electronic frog eyes in radar system, the anti-jamming ability of radar is greatly improved. This radar system can quickly and accurately identify aircraft, ships and missiles with specific shapes. In particular, it can distinguish between true and false missiles and prevent false confusion.

Electronic frog eyes are also widely used in airports and traffic arteries. At the airport, it can monitor the take-off and landing of aircraft, and call the police in time if it is found that the aircraft is about to collide. On the main road, you can direct the vehicles to prevent them from colliding.

People have successfully designed an accurate "jellyfish ear" instrument by simulating the organs of jellyfish that feel infrasound waves. It consists of a loudspeaker, a vibrator for receiving infrasound waves, a transducer for converting this vibration into electric pulses and an indicator. This instrument is installed on the front deck of the ship, and the horn rotates 360. When it receives 8 Hz- 13 Hz infrasound, the rotation stops automatically, and the direction indicated by the horn is the coming direction of the storm. Indicators can also tell people the intensity of the storm. This instrument can forecast storms 15 hours in advance.

The compound eyes on both sides have the greatest influence on the behavior of horseshoe crab. After being irradiated by the light beam, the compound eye produces a pulse. One eye is irradiated by the light beam, and the other eye generates the main pulse; Both eyes are irradiated by light beam at the same time, and both eyes generate pulses at the same time, but the frequency of pulses generated by light beam irradiation on one eye is slightly lower. Inspired by it, mankind has successfully developed an electronic simulation device, which can solve the network equation composed of 10 elements. The TV camera made by applying this principle can provide high-definition TV images under laser.

Without nature, there would be no beautiful earth. Let's join hands to protect nature and the earth.

Someone once tied a wire to two trees not far apart in order to dry things. Over time, the hoop formed by iron wire was firmly pulled into the trunk, leaving a deep impression. That seemingly destiny takes a hand tree miraculously swallowed a heartless hoop! And all this happened to be seen by a terminally ill and extremely pessimistic old man. It is this tree that guides him and makes him regain the courage to live! Deeply moved, he bowed deeply to the tree and decided to fight the disease to the end!

It is better to say that nature is enlightening all beings than that this tree has saved a life; Treat life rationally, treat life.

Some people have a lot of smoke in their bright eyes because of the failure of their work; Some students, because of the failure of the exam, the world suddenly eclipsed in his eyes. However, there are thousands of roads to success, all of which are bumpy. As long as you work hard wholeheartedly, the future will be bright and green. As long as you work hard, there is a way where there is a will.

People who live in the shadows all day have ever thought: Chimonanthus praecox hates the ravages and mowgli of winter, but it still exudes fragrance in the cold winter; Perhaps fish hate the rough and fierce waves, but they are still accompanied by the waves, fulfilling the true meaning of life; Fallen leaves are attached to this world. However, as soon as the autumn wind blows, it will resolutely fall, bid farewell to the beautiful world, and care for the grassroots that will sprout next year.

In the long journey of life, people's hearts need to be vast under the blue sky and need to be baptized by the wind and frost sword; Need to swim in the sea and accept the test of stormy waves; You need to gallop in the wilderness and be honed by the thorny swamp, so that people will have a rational heart.

Wipe the dust off your eyes-see the world clearly; Let go of your prejudice-distinguish right from wrong.

The revelation of nature.

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.

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?

butterfly

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 the scales on the butterfly will automatically change their angles with the direction of sunlight to adjust their body temperature, scientists have made the temperature control system of the satellite into a louver style, which has different radiation and heat dissipation capabilities. A temperature-sensitive metal wire is installed at the rotating position of each window, which can adjust the opening and closing of the window 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.

beetle

When the beetle defends itself, it can spray a smelly high-temperature liquid "shell" to confuse, stimulate and scare the enemy. After dissection, scientists found that there are three chambers in the beetle body, which store dihydric phenol solution, hydrogen peroxide and biological enzyme respectively. Diphenol and hydrogen peroxide flow into the third chamber and mix with biological enzyme to have a chemical reaction, which instantly becomes venom at 100℃ and is quickly ejected. This principle has been applied to military technology at present. During World War II, the German Nazis made a new engine with huge power and safe and reliable performance according to this mechanism, which was installed on cruise missiles, making it fly faster, safer and more stable, and improving the hit rate. London, England suffered heavy losses when it was bombed. American military experts have developed advanced binary weapons inspired by the principle of beetle spraying. This weapon contains two or more chemicals that can produce toxins in two separate containers. After the projectile was launched, the diaphragm broke, and the two poison intermediates mixed and reacted within 8- 10 seconds of the projectile's flight, producing deadly venom at the moment when it reached the target and killed the enemy. They are easy to produce, store and transport, safe and not easy to fail. Fireflies can directly convert chemical energy into light energy, and the conversion efficiency reaches 100%, while the luminous efficiency of ordinary electric lamps is only 6%. The cold light source made by people imitating the luminous principle of fireflies can improve luminous efficiency by more than ten times and save energy greatly. In addition, an air-to-ground speedometer based on beetle apparent motion response mechanism has been successfully applied to aviation.

dragonfly

Dragonflies can generate local unstable airflow different from the surrounding atmosphere through the vibration of their wings, and use the vortex generated by the airflow to make themselves rise. Dragonflies can soar under a small thrust, not only forward, but also backward and left and right, and its forward flight speed can reach 72 km/h. In addition, the flight behavior of dragonflies is simple, with only two pairs of wings flapping constantly. Scientists have successfully developed a helicopter based on this structural foundation. When an airplane flies at high speed, it often causes violent vibration, and sometimes even breaks its wings, causing the airplane to crash. Dragonflies are safe when flying at high speed, so people follow the example of dragonflies and add weights to the two wings of the plane to solve the thorny problem of vibration caused by high-speed flight.

In order to study the aerodynamics and flight efficiency of gliding flight and collision, a mobile wing (wing) model with four-blade drive and remote horizontal control was developed, and the flight parameters were tested in the wind tunnel for the first time.

The second model tries to install a wing flying at a faster frequency, reaching the speed of 18 vibrations per second. What is different is that this model adopts a device that can variably adjust the phase difference between the front and rear wings.

The central and long-term goal of this research is to study the performance of aircraft driven by "wing" and compare it with the efficiency of aircraft driven by traditional propeller.

fly

The special feature of housefly is its fast flying technology, which makes it difficult to be caught by humans. Even behind it, it is difficult to get close to it. It imagines every situation, is very careful and can move quickly. So, how did it do it?

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 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 the object can be seen clearly in 360 degrees. 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.
