The revelation of nature

Colorful butterflies, such as those with double moon patterns, those with brown veins, especially those with fluorescent wings, have golden wings, green wings and blue wings 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, although the Germans went all out, the military base in Leningrad remained undisturbed, 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.

Beehives are composed of small hexagonal beehives, and the bottom of each beehive is composed of three identical diamonds, which are exactly the same as those calculated by modern mathematicians-rhombic obtuse angle 109. 28', acute angle 70. 32' is exactly the same, it is the most material-saving structure, and it has a large capacity and is extremely strong, which makes many experts admire it. People imitate its structure and make honeycomb sandwich structural plates with various materials. This structural plate has high strength, light weight and is not easy to conduct sound and heat. They are ideal materials for making space shuttles, spaceships and artificial satellites. Polarizers sensitive to the direction of polarized light are arranged adjacent to each eye of the compound eye of bees, which can be accurately positioned by the sun. Based on this principle, scientists have successfully developed a polarized light navigator, which has been widely used in navigation.

Dragonflies can generate local unstable airflow different from the surrounding atmosphere through the vibration of their wings, while Wells uses the vortex generated by the airflow to lift himself up. 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 rely on aggravated wing moles to fly safely 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.

Fleas have a high jumping ability, and aviation experts have done a lot of research on it. Inspired by its vertical take-off, a British aircraft manufacturing company successfully manufactured a Harrier aircraft that can take off and land almost vertically. According to the structural characteristics of insects' single compound eyes, modern television technology has created a large-screen color TV, which can also be composed of small color TV screens. Some specific small pictures can be framed at any position on the same screen, and the same picture can be played as well as different pictures. According to the structural characteristics of insect compound eyes, scientists have successfully developed a multi-aperture optical system device that is easier to find targets, and it has been applied in some important weapon systems abroad. According to the mutual inhibition principle of some aquatic insects compound eyes, an electronic model of lateral inhibition is made, which can be used in various photographic systems. The photos taken can enhance the edge contrast of the image and highlight the outline of the image, and can also be used to improve the display sensitivity of radar, and can also be used for the preprocessing of text and picture recognition systems. Based on the processing information of insect compound eye and the principle of directional navigation, the United States has developed an engineering model of terminal guidance seeker with great practical value. Japan has developed new construction methods of construction machinery and buildings such as hexapod robots by using the morphology and characteristics of insects.

From Seepage Prevention of Yuanmingyuan Lake to "Man can conquer nature"

Recently, Yuanmingyuan spent a lot of money to "lay the bottom of the lake", which was clearly opposed by many environmental experts and environmentalists. The reason of Yuanmingyuan Management Office is to prevent water leakage and save water charges. The main objections of environmental experts are:

1. The anti-seepage project will block the last passage of 100 hectares of rainwater to the underground, and the ecological environment of 100 hectares of wetland will be destroyed, losing the largest natural wetland in Haidian District, Beijing; Secondly, Yuanmingyuan Lake is an ecosystem, and a large number of underwater microorganisms silently undertake the responsibility of inhaling carbon dioxide garbage and fish manure, recreating oxygen organic matter, and letting the clear fish swim happily in the lake; Now covering with plastic sheets will destroy the activities of microorganisms and the whole ecosystem will collapse. In the end, the whole lake turned into a stagnant water, the river stinked in an all-round way, and the dead fish on the river turned over, causing ecological catastrophe; Third, the practice of blocking stone crevices completely destroyed the original natural ecological balance, and the plants on the shore can only rely entirely on artificial watering in the future, which is not conducive to water saving.

When it comes to environmental protection, we immediately think of the opposition between environmental protection and economic development, even if it is temporary. Specific to the "Yuanmingyuan Lake Leakage Prevention" project, whoever believes that time is fair will have his own views in a few years. According to the latest report, the whole anti-seepage project at the bottom of the lake needs about 30 million yuan, which can save water fee10 million yuan every year, and the cost can be recovered in three years. The seemingly simple economic account does not consider the ecological cost. The ecological cost may not have much to do with Yuanmingyuan itself, but it is related to the surrounding residents, to the ecological environment of the whole region, and to the ecological environment of the whole city, the whole country and even the whole earth. The Amazon rainforest is called the lungs of the earth. If the lungs can't work effectively and normally to maintain the ecological balance of the whole earth, it will be disastrous.

There are "too many things" that human beings can do, and it is not a problem to go to heaven and go to earth. Humans always have the inner impulse to conquer nature, and always think that "man can conquer nature", but most of them are punished by nature. Sanmenxia hydropower station is an extreme example; During the Cultural Revolution, artificial terraces were built all over the country, farmland was built around water, and forests were destroyed to grow grain. There are countless examples of this violation of the laws of nature. What is the final result? Causing soil erosion and serious ecological imbalance. Humans have to return farmland to forests, plant trees and grass in the desert, maintain the simple balance of nature and seek human survival.

With the progress and development of human science and technology, there are more and more ways for human beings to influence nature. Less precipitation? Artificial precipitation enhancement. Perhaps one day, humans can control the direction of clouds in the sky and move them to places where it needs rain, which is much more convenient and cheaper than the "South-to-North Water Diversion Project" on the ground. If there is such a day, it will pose a greater threat to the survival of mankind.

Man's greatest enemy is actually himself. In order to produce more eggs, produce more meat and satisfy human appetite, human beings "invented" lean pigs fed with "broilers", "stuffed ducks" and "lean meat". What does eating meat bring to human beings? Violating the laws of nature will inevitably be punished by them. This kind of punishment may take decades or hundreds of years to appear.

In the end, it can only be human beings themselves. It is better to be kind to the natural environment and have more reverence for nature, so as to achieve harmony and balance. Being kind to nature means being kind to yourself. Respondents: Enthusiastic users | 2011-3-2714: 28

After reading the book Animal World, I learned about the life characteristics and special abilities of woodpeckers and anteaters. From them, I suddenly thought of a problem and got an inspiration:

In rural orchards, we often find pests getting into tree trunks and ripe fruits. In order to protect the fruit trees, farmers have to spray a lot of pesticides. What is the result? Not only is the cost high, but people eat it, and the pesticides that exceed the standard are scary. If pests are not killed in time, people have to cut down those "incurable" fruit trees. In modern rural areas, it is impossible for so many woodpeckers to help fruit trees see a doctor.

Nature has given people a lot of inspiration. Planes were invented according to dragonflies, and streamlined boats were invented after whales at the bottom of the sea. So I'm thinking: why don't we make a portable pest control machine by imitating the mouth of woodpecker and the tongue of anteater? In this pest control machine, we can install a computer chip, so that it can accurately detect diseased trees. Then, we can press a red button on the handle, and a pointed hooked steel pipe similar to a woodpecker's mouth will pop out from it. It can accurately make a tiny hole in a tree with pests, and then hook it out with a hooked steel pipe mouth. What about termites? Don't panic, we can put the steel pipe mouth in first, then press the green button, and an anteater-like tongue will pop out of it. As soon as the sticky long tongue "drills" into the hole, termites are easily and completely eliminated.

From the foraging of woodpeckers and anteaters, we got an inspiration and an innovation.

The revelation of nature

Japanese scientists were inspired by ants foraging. They developed a large-scale integrated circuit to simulate the foraging ants Qixin carrying food together and sending information from the nearest "food source" to the "ant nest" in sequence. According to this new information processing method, it is possible for people to develop a new computing mode computer.

There are still many inspirations that human beings get from nature. For example, an arch bridge was built to imitate the characteristics of egg shape; Inspired by the flight of birds, people invented airplanes. I cut off my fingers from the thatch and invented the saw ... Many animals and plants in nature, with their own unique lifestyles, hint at the mysteries of nature.

There are many inspirations from nature. There is a kind of snake called rattlesnake. It has an infrared eye. Through the eyes of this snake, human beings have developed a missile with eyes like rattlesnakes. Its name is rattlesnake missile, so it is named rattlesnake missile, because humans are made according to the eyes of rattlesnakes.

The rattlesnake missile, like the rattlesnake, can accurately track the enemy with its "hot eyes" until it is destroyed. Because the "hot eyes" of the rattlesnake can judge the position of the enemy according to the temperature of the enemy, the rattlesnake missile can accurately hit planes, warships, tanks and the like. A maneuvering low-altitude short-range all-weather ground-to-air missile developed by France. It is mainly used to deal with low-altitude and ultra-low-altitude fighters and armed helicopters to defend airports and ports, and can also be used to deal with cruise missiles. The missile is 2.94 meters long, with a diameter of 0. 156 meters, a weight of 84.5 kilograms and a launcher length of 3.02 meters. The warhead focuses on fragments, with a total weight of 13.9 kg and a killing radius of 6 ~ 8 meters. The power plant is a single-stage solid rocket engine, and the guidance mode is full-range radio command guidance, with an operational radius of 500-8500m and an operational altitude of 50-3000m. The missile has semi-off-road maneuverability.

Second, the importance of teamwork.

1, ant: Ant is a typical social insect, which has three elements of social insects, that is, individuals of the same species can cooperate with each other to take care of their larvae; Have a clear division of labor system; And future generations can take care of the previous generation for a while. Ants develop into complete metamorphosis. All ants live in social groups. Generally speaking, there are four different kinds of ants in a group. L, queen ant; 2. Male ant 3. Worker ant 4. soldier ant

2. Wolf: Wolf is one of the most orderly and disciplined animals in the animal kingdom. It shows a strong team spirit. The wolf's team spirit is manifested in the following aspects: 1. Overall and individual: the social order of wolves is very firm, and each member understands his role and status. All actions depend on the position of each member of the pack. The reason for howling is to provide time, occasion and opportunity to break all the hierarchical boundaries. When wolves howl together, all the hierarchy boundaries disappear. 6. Wolves are good at communication. They are one of the most sociable animals. They don't just rely on a single way of communication. Instead, they need to use various methods. They howl, rub their noses against each other, lick with their tongues, adopt dominant or subordinate body posture, and use complex and subtle body language including lips, eyes, facial expressions and tail position or smell to convey information.

3. Lions: Lions are social animals. A lion group usually consists of 4- 12 related lionesses, their children and 1-6 lions. These lions are often related by blood, such as brothers. The size of a lion depends on its habitat and the number of prey. Lions in East Africa tend to be bigger because there is plenty of food there. The largest lion may gather 30 or more members, but most lions maintain about 15 members, and smaller lions are also common. Members of the lions don't always stay together, but they enjoy their territory and get along well with each other. For example, lionesses lick each other's fur, nurse and look after their children, and of course, hunt together.

...........

Third, specific spiritual wealth.

1, Dog: "Man and dog are one", and the harmony between man and nature is also the proper meaning of building a harmonious society. The dog's loyalty, intelligence, courage and extraordinary skill have established its "due" status, especially those rare dog breeds, which have made magic and contributions to dogs in many fields such as quarantine, security inspection, drug control, criminal investigation, search and rescue, and blind guidance. Genghis Khan once led hundreds of thousands of mastiffs across Europe, which became an eternal beauty talk. In this sense, dogs are "good friends" of human beings. With dogs, human beings will be safer, and with dogs, life will be more meaningful.

Therefore, cherishing, protecting, developing and utilizing "dog resources" for the benefit of society has naturally become a self-evident blessing and responsibility of human beings, and the spiritual quality of dogs is more worthy of our exploration, reference and promotion.

2. Plum blossom:

The plum blossom, the first of the twenty-four flowers, has green ice branches, elegant shadow, beautiful fragrance and early flowering. "Xiang Xuehai dares to produce thousands of flowers, and a tree will spring first." Known as the flower base. The lofty character and loyalty of "knowing far away is not snow, only fragrance comes" symbolizes the spirit of our descendants of the dragon. Plum blossom cultivation began in Shang Dynasty and has a history of nearly 4000 years. Mei is the birthday girl among flowers. In many parts of China, the Millennium Gu Mei is still preserved. In Huangmei County, Hubei Province, there is a golden plum, which is 1600 years old and still in bloom. Plum blossoms are in full bloom in the snow, the fragrance is lingering in the cold, the image of iron bones and ice hearts, and the image of high morality and integrity inspires people to strive for self-improvement and persevere in welcoming the arrival of spring. "Wind and rain send spring home, flying snow welcomes the spring. It is already a cliff full of ice, and there are beautiful flowers, which do not compete for spring. They only reported the spring solstice, and she was laughing at it. "

3. Bamboo:

Bamboo sticks are tall and straight, slender, graceful, evergreen all the year round, and stand proudly in the wind and rain. They are deeply loved by people, especially literati, who like to compare themselves to bamboo, symbolizing honest and frank, purity and iron. Bamboo has always enjoyed a high reputation, including "Mei Zhu Lan Ju", one of the four gentlemen, and "Mei Songzhu", one of the three friends, which has been deeply loved by people since ancient times. Some people praise bamboo as "open-minded, bamboo has Qian Qian Festival"; Zheng Banqiao, a great painter, wrote a poem for bamboo, "Insist that the green hills will not relax ...". There are many literati and poets in ancient and modern China who love to chant bamboo. It is said that there is no bamboo to live in here, leaving many bamboo paintings and poems about bamboo. Su Dongpo, a great poet, left a famous saying that "living without bamboo is better than eating without meat".

4. Pine tree: it is indomitable, not afraid of wind and frost, and the spirit of constant seasons. How can we not think of the PLA soldiers who guard the motherland day and night and devote themselves to it? Moreover, it doesn't need fertilization and irrigation, and the wind can't blow it down; Flood can't drown it, nor can cold damage it. It just tries to stay still.

Chrysanthemum: It is beautiful and colorful, but it won the favor not with its exquisite beauty, but with its simple elegance and firmness, and bloomed after the flowers faded. People love its exquisite charm, and even more love its first frost west wind in full bloom. China endowed it with noble and strong feelings and regarded it as a symbol of national spirit. Chrysanthemum, as the flower of Ao Shuang, has always been favored by poets. The ancients especially liked to name it after chrysanthemum, which was a metaphor for its noble sentiment and unyielding loyalty.

5. Chrysanthemum:

People in China like chrysanthemums very much. Since the Song Dynasty, there has been an annual Chrysanthemum Festival among the people. In ancient myths and legends, chrysanthemum was endowed with the meaning of good luck and longevity. For example, the combination of chrysanthemum and magpie means "family happiness"; The combination of chrysanthemum and pine is "longevity" and so on, which is widely used in folk.
