Information about nature

Fish have the ability to come and go freely in the water, so people imitate the shape of fish to build boats, using wooden paddles to imitate fins. It is said that as early as the period of Dayu, the working people of ancient my country observed fish swimming and turning in the water with the swing of their tails, and they set up wooden oars on the stern of the boat. Through repeated observation, imitation and practice, he gradually changed to oars and rudders, increased the power of the ship, and mastered the means of turning the ship. In this way, people can make ships sail freely even in rough rivers.

The fly's wings (also called balance rods) are "natural navigators", and people imitated them to make "vibrating gyroscopes". This kind of instrument has been used in rockets and high-speed aircraft to realize automatic driving.

The eye of a fly is a kind of "compound eye", consisting of more than 3000 small eyes. People imitate it to make "fly eye lenses". A "fly's eye lens" is made up of hundreds or thousands of small lenses arranged neatly together. It can be used as a lens to make a "fly's eye camera", which can take thousands of the same photos at one time. This kind of camera has been used in printing plate making and large-scale reproduction of tiny circuits in electronic computers, greatly improving work efficiency and quality. The "fly's eye lens" is a new type of optical component that has many uses.

The wings of birds have many special functions and structures, making them not only good at flying, but also able to perform many "stunts" that are difficult to achieve with current human technology. The little hummingbird is the "helicopter" among birds. It can take off and land vertically, and fly backwards. When sucking nectar, it does not sit on the flower like a bee, but hovers in the air. What a neat flight it was. Building a vertical take-off and landing aircraft with the flight characteristics of a hummingbird has become the dream of many aircraft designers.

Inspired by Penguin, people designed a new type of car "Penguin Polar Off-Road Vehicle". This kind of car uses a wide bottom to stick to the snow and uses a wheel scoop to push forward. This not only solves the problem of polar transportation, but also can drive in muddy areas.

The eyes of flies invented the fly-eye camera.

The fly's sensitive perception invented the hazard detector, which is used in dangerous workplaces

The eagle's gliding skills invented the glider.

The lines left by the birds change the appearance of the aircraft and make it more aerodynamic.

Bird bones improve the skeleton structure of the aircraft, making it lighter and stronger.

Acoustic detection of bats and dolphins, and the invention of ultrasonic radar.

People are inspired by bats to fly at night with radar.

Cactuses and ants are natural things that can be seen everywhere, so they are not unusual, but don’t underestimate them. Look at them.

Have you ever seen a group of tiny ants crawling on the wall? They always carry food as small as sand and move around in groups. With its small body, its life is very fragile. As long as it is pressed by someone, its life may end like this. Although ants are small, they are very united. An ant finds food. Because the food is too large to be carried by itself, it immediately returns to the nest and informs its partners. If everyone unites together, they can succeed. The same goes for us. If we cannot unite, we will be like a piece of loose sand with no strength at all. If we can cooperate, we will be able to stand firm in our lives.

Cacti live in desert areas, where it is extremely hot and there are many vicious beasts, making the situation very dangerous. However, the cactus has lived there for a long time, but it has not become extinct. This is because in order to adapt to the dangerous environment, it has grown sharp thorns, leaving animals helpless. This seems to tell us that we must overcome difficulties and rely on our own strong perseverance to solve the difficult external environment. As the saying goes: "Nothing is difficult in the world, as long as there are people who are willing." This is the truth.

There are so many inspirations for us in nature. As long as we understand it with our hearts, we can have a deeper understanding of life. Cactuses and ants are not all good examples. ? Answered by: hujinhui12 | Level 1 | 2009-3-21 10:45

Overview

About nature - water, air, mountains, rivers, microorganisms, plants, animals, The earth, the universe, etc., all belong to the category of nature; the science that studies nature is natural science, including mathematics, physics, chemistry, biology, geography and other sciences, and the branches of these sciences are very numerous and complicated. For example, biological science can be divided into three major disciplines: microbiology, botany, and zoology; it can further be divided into molecular biology, cytology, genetics, physiology, etc.; the intersection of various disciplines will lead to many sub-disciplines. Such as biochemistry, biophysics, molecular structural biology, etc.

Man and Nature

Nature gave birth to human beings, which shows that it respects human behavior. On the contrary, human beings should respect nature even more. On the surface, it seems that humans are born from parents. In fact, it is nature that has photon information about humans. Only then can human embryos absorb this photon information from nature and grow the embryos into adults. They are born from parents and are completed by nature at the same time. Excitation of embryonic dark matter. There are 45,336 species of vertebrates in nature, including 1,244 species of birds and 3,862 species of fish. There are more than 3 million species of insects, and only more than 1 million species have been confirmed.

Nature is a natural resource. People and nature should respect each other, maintain a cherishing and cherishing mentality, use nature appropriately, and prevent nature from being destroyed, so that the living environment is beautiful and natural resources are not exhausted. They are as close and harmonious as mother and child. .

Therefore, the richness of information about nature can only be described as vast, and its complexity cannot be explained by 30,000 to 20,000 words or a few people.

Classification of nature

There are various living things in nature, including three major categories: plants, animals, bacteria and fungi. At the same time, nature is also a system that contains various ecosystems The place!

The elements of nature are divided into seven types: 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 first in terms of time and most important in terms of place. Every day, the sun; after sunset, the night, with her stars. The wind always blows; the grass always grows. Every day, men and women talk, watch, and are watched. Of all people, that image is most attractive to philosophers. He must decide in his own mind its value. What does nature look like to him? This web of God, its incomprehensible continuity, never begins, never ends, is always the circular force returning to itself. In this it was like his own soul, whose beginning and end he could never find - so complete, so infinite. The brilliance of nature also shines so far. There is a universe above the universe, radiating out like rays of light, up and down, without a center or a circle - whether it is gathered or dispersed, nature is eager to reach out. The human soul expresses itself.

Began to be divided into categories. In the hearts of young people, everything is individual and stands alone. Gradually, he figured out how to join two things together and see their identity; then three things, then 3,000; then he was dominated by his own instinct to unite everything and continued to put them together. Things are tied together, irregularities are reduced, roots are discovered underground, opposite and distant things are connected, and they bloom on the same branch.

He soon learned that since the beginning of history, facts had been continuously gathered and classified. But what does “classification” mean? It is nothing more than seeing that these things are not chaotic and have no relationship with each other, but have certain laws, which are also the laws of the human mind. Geometry was purely an abstraction of the human mind, and astronomers discovered that the motion of the planets could be measured geometrically. Chemists discover that there are proportions and understandable laws in all matter; what is science? It is nothing more than finding similarities and similarities in things that are farthest away. An ambitious man sat down to study every uncontrollable fact; one by one he assigned all the strange structures and all the new powers to their categories. reduced to their theorems, and evermore so, using deep observation to give life to the last fiber of every tissue, and to the outer edges of nature.

As a result, the schoolchild under this sky feels that he and nature are "originally born from the same root"; one is a leaf, the other is a flower; friendship and sympathy are flowing in every blood vessel.

What are tree roots? Is it not the soul of his soul? An idea that is too bold; a dream that is too absurd. However, once the brilliance of the soul helps him discover the laws of more tangible physical properties - when he knows how to worship the soul and sees that the existing natural philosophy is only the initial exploration of the giant hand of the soul, then he will I hope that knowledge will expand day by day so that I can become a future creator. He will see that nature is the opposite of the soul, and that every part corresponds to it. One is a seal and the other is printed words. Its beauty is the beauty of his own soul. Its laws are the laws of his own soul. He therefore looked upon nature as the measurer of his own achievements.

To the extent that he does not know enough about nature, that is to say, he does not have enough control over his own mind. In short, the ancient motto, "Know thyself," and the modern motto, "Study nature," have finally become the same motto.

Modern radar - a radio positioning and ranging device: Scientists have found that bats do not rely on their eyes, but on The echolocation system consists of the mouth, throat and ears. Because bats emit ultrasonic waves when flying, they can also detect ultrasonic waves reflected back from obstacles.

Based on this, scientists designed a modern radar - a radio positioning and ranging device

Through research on the low swimming resistance of dolphins, scientists invented artificial dolphin skin that can increase the speed of torpedoes; and imitated the movement of kangaroos. Wheelless vehicles (jumping machines) in the form of desert sports, etc.

Inspired by penguins, scientists from the Institute of Zoology of the Academy of Sciences of the former Soviet Union designed a new type of car - the "Penguin" brand polar off-road vehicle. The wide bottom of this kind of car is directly attached to the snow surface, and it is propelled forward by the wheel scoop, and the driving speed can reach 50 kilometers per hour.

Scientists imitated insects to create space robots. A research team at the Australian National University has developed a small navigation and flight control device through research on several insects. This device could be used to equip small aircraft for Mars exploration.

Inspired by bionics, British scientists are developing a submarine that can "swim" in an S-shape by swinging its tail fin. The main innovation of the new submarine is the use of what is called an "elephant trunk actuator" " device. The "trunk" consists of a set of flexible tubes made of thin, flexible material that mimic muscle activity to propel the fin's movement. This new submarine can serve as an underwater minesweeper, used to deal with mines that can detonate at the slightest sound or disturbance.

Inspiration from nature

Cacti, ants, these natural things They are found everywhere, so they are not unusual, but don’t underestimate them.

There are so many inspirations for us in nature. As long as we understand it with our hearts, we can have a deeper understanding of life. Cactuses and ants are not all good examples. ?

-----------------------------

The ancients once said a very profound saying Words: Learn from nature. Well said! Nature has indeed taught us many lessons, and each lesson is more beautiful than the last. Please listen to three stories first.

Story 1: AB was originally two unrelated trees, but because they were tightly entangled with ivy, they grew together unknowingly. Since then, tree A has also grown together. A brand new fruit is produced, which still looks like A, but tastes exactly like B. Look! Nature is so wonderful. With such an inspiration, the horticulturist suddenly understood and learned to graft in one fell swoop.

Story 2: In order to dry clothes, someone once tied iron wires to two trees not far apart. Over time, the iron wires formed iron hoops and were firmly inserted into the trunks of the trees. There was a deep groove on it. Two years later, the iron hoop was deeply strangled into the tree. The poor tree seemed certain to die, but a miracle happened because of this. Instead of being strangled, the strong tree stood firm. , He just swallowed the terrible iron hoop alive! And all this happened to be seen by an extremely desperate old man, and he gained the courage to live again. The old man has cancer! He overcame his illness and survived. He lived for several more years, and the last words he said before he died were: Thank you for that tree! Look! Nature is so profound. Although it is silent, it can give people extraordinary power.

Story 3: Do you know the origin of pearls? Although they are as magnificent as stars, their origins are like a very scary and very long dream. This terrible nightmare began when a pebble suddenly fell into the tender body of the pearl oyster! The rough stones tortured and stung it day and night, but it was extremely strong. Not only did it accept the sudden pain, but it also clenched its teeth resolutely, silently, and so on for another year. A year until it turned into a shining pearl. This is an even more thrilling lesson! Does nature tell us in its unique way the meaning of suffering? It is a kind of sacred tempering. Yes, there are many similar stories. The mature wheat ears lower their heads, which is teaching us humility.

A group of ants can lift big bones, which teaches us unity. Gentle water drops can drip through rocks, which teaches us perseverance. Bees are busy shuttling among the flowers, which teaches us to be diligent. The hamcha grass silently closes its leaves, which tells us not to overdo it. Yes, nature is the best teacher.

As long as we are willing to learn, we will gain something every day

Cactus, ants, these natural things can be found everywhere, so they are not uncommon, but you should not underestimate them.

Are you I have seen a group of tiny ants crawling on the wall. They are always carrying food as small as sand and moving in groups. Those small bodies are very fragile. As long as they are pressed by someone, their whole life will be ruined. It may end like this. Although ants are small, they are very united. When an ant finds food, but the food is too large to be carried by itself, it immediately returns to the nest and informs its partners. If we unite together, we will succeed. We The same is true, if we cannot unite, we are like a plate of loose sand, with no strength at all; if we can cooperate, we can stand firm in life.

Cacti live in desert areas, where it is extremely hot, and there are many The vicious beast is in a very dangerous situation. However, the cactus has lived there for a long time, but it has not become extinct. This is because in order to adapt to the dangerous environment, it has grown sharp thorns, leaving the animals helpless. This seems to tell us that we must overcome difficulties. , the external difficult environment must be solved by one's own strong perseverance. As the saying goes: "Nothing is difficult in the world, only those who are willing to do so." This is the truth.

The inspiration given to us in nature is too great. There are many, as long as we experience it with our hearts, we can have a deeper understanding of life, like cacti and ants, aren’t they all good examples?
