Tao Yuanming loves mountains, empty mountains, away from the hubbub, filled with the simplicity of nature; Mountain, with its calm and fresh loneliness, makes the hermit suddenly realize the meaning of life, so there is the eternal famous sentence of Tao Yuanming picking chrysanthemums under the east fence and leisurely seeing Nanshan; So there was a wise man who saw through the dust, hated the world and lived in seclusion in the mountains; So I had it and will rest at the foot of Nanshan. Exquisite, carefree and distant mountains and dusk, Qingming, the white clouds that go home, the silence that "the mountain is inclined but welcoming guests", and the helplessness of "taking advantage of this mountain to command the Hanjiang River". In the world, it gives people strength, naturalized purity, and courage to follow the crowd. Wise people love mountains because they see the vicissitudes of life in the abrupt peaks and feel the belonging of life.
The mountain is silent, but it interprets the philosophy of life with silence. When you look at the prosperity, you will wash your mind with the breadth of the mountain and show your childlike innocence; When you are not strong-willed, you will see that Dashan encourages you to forge ahead with its broad mind and immortal persistence. Mountains are heaven. Here, there is no intrigue, no flattery, only the revelation of natural nature.
As the saying goes: the wind and water are flourishing, and the benevolent enjoys water.
Li Bai and love the water, a trickle, filter out people's troubles with their clever and meaningful melodies and arouse people's reverie with their swaying amorous feelings. So there was Li Bai's "Peach blossoms and flowing water suddenly passed away, and there was another world that was not human". Therefore, there is the poignant beauty of "a pool of running water and a pool of moon", the regret that the deceased stayed up all night, the feeling that the rough waves rolled up thousands of piles of snow, and the wisdom that "the flow is endless". Water gives people a spiritual beauty, a lingering sadness or a silent attachment to the East. Water gives people emotional delicacy, just like a girl holding an oil umbrella and lilacs in a "rain lane", which makes people daydream and think deeply. Benevolent love the water, because they saw life in the tinkling water, seems to be a pair of bright eyes full of amorous feelings, and there is always a kind of insight into people's hearts.
Water is silent, but it reveals the ethics of life with the spirit of flowing. Fire is strong enough to draw fire with water, which is the way of combining rigidity with softness. Water makes people communicate, and the land with water is full of vitality and vitality. Water also warns people that the past cannot be chased, and the whole meaning of life is only today; Water is the embodiment of the spirit, but it will roar and roll like a runaway wild horse, so water is also a powerful hidden body, with rigidity in softness and holiness in softness; Gentle and bold, weak and slightly tough, it is a replica of such a perfect personality.
As the saying goes: looking at the mountains and watching the sea, the body has not moved, and the heart is far away.
One flower and one world, one thing and one Tai Chi; We rely on mountains and rivers to express our feelings through water; The use of mountains makes us open-minded, and the use of water makes us introverted. A wise man should have both. Landscape is the source of life, which nourishes the moral theory of our Chinese nation for thousands of years and is a philosophy that we need to experience all our lives.

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.
