Nature s revelations to humanity as well as inventions and creations

The eye of the fly, the fly's eye camera was invented.

The sensitivity of flies led to the invention of hazard detectors, and the glider was invented with the gliding skills of eagles in dangerous workplaces.

The shape of the bird's line changes the shape of the aircraft and is more aerodynamic.

The bones of birds, which have improved the skeleton structure of the aircraft, are lighter and stronger.

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

Airplanes flying at night on radar are the inspiration people take from bats.

I would like you to help me find this topic: Nature's Revelation to Humanity. It is a question that tells us to obey the way of nature and not to violate the way of nature.

For example, in Lesson 9 of the second volume of the fourth grade, the topic is The Way of Nature, which tells the story of the young turtle, which also shows that we need to understand and respect the laws of nature. Also, when the praying mantis is dating, the female mantis wants to eat the male mantis, and if you stop it, that's not right, it's the way of nature.

You tell me to be brief: e.g. Praying Mantis - Female mantis eats male mantis.

The walls are wet – it's going to rain.

Ants move – it's going to rain.

Spider webs - to go down.

Spring planting and autumn harvesting. The use of the 24 solar terms.

Time is extrapolated from the angle of sunlight.

Utilization of windmills.

The invention of the saw blade.

The use of the fan.

The colors of the colorful butterflies are very natural, such as the heavy moon butterfly, the brown vein golden spotted butterfly, etc., especially the fluorescent winged butterfly, which is sometimes golden in the sun, sometimes emerald green, and sometimes from purple to blue. Scientists have been able to study the colors of butterflies for military defense. During World War II, the Germans surrounded Leningrad in an attempt to destroy its military targets and other defenses with bombers.

Based on the lack of understanding of camouflage at that time, the Soviet entomologist Schwanvich proposed to cover military facilities with butterfly-like camouflage by using the color of butterflies that are not easy to be found in flowers. Thus, despite the efforts of the Germans, the military base in Leningrad remained unharmed, laying a solid foundation for winning the final victory. According to the same principle, later people also produced camouflage uniforms, which significantly reduced the number of ** in battle.

The story of Lu Ban's invention of the saw has been circulating among the people for thousands of years.

Legend has it that one year, Luban accepted a task to build a huge palace. The palace needed a lot of wood, so Lu Ban asked his apprentices to go up the mountain to cut down trees. Since there were no saws at the time, his apprentices had to use axes to cut down, but this was very inefficient, and the craftsmen got up early and worked hard every day.

Exhausted, unable to cut down many trees, far from meeting the needs of the project, the progress of the project has been delayed again and again, and seeing that the deadline for the project is getting closer and closer, this can be a bad thing for Luban. For this reason, he decided to go up to the mountain to inspect the felling of trees himself. When he was going up the mountain, because he was careless, he accidentally grabbed a handful of wild grass that grew on the mountain, but he cut his hand at once.

Lu Ban is very strange, why is a piece of grass so sharp? So he plucked a leaf and looked closely, and found that there were many small teeth on both sides of the leaf, and when he touched it lightly with his hand, these small teeth were very sharp. He understood, his hand had been cut by these tiny teeth.

Later, Lu Ban saw a big locust gnawing on a grass plant, and the two big teeth were very sharp, opening and closing, and soon ate a large piece. This also aroused Lu Ban's curiosity, he grabbed a locust, carefully observed the structure of the locust's teeth, and found that the locust's two large teeth were also lined with many small teeth, and it was on these small teeth that the locust relied on to bite off the blades of grass. These two events left an extremely deep impression on Lu Ban, and also made him very inspired and fell into deep thinking.

He thought, wouldn't it be equally sharp if the tools used to cut wood were made jagged? It's much easier to cut down trees. So he used the big bamboo to make a bamboo piece with many small serrations, and then went to the small tree to do the experiment, the result was really good, a few times the bark was broken, and then a few more hard pulls, the small tree pole drew a deep ditch, Lu Ban was very happy.

However, because the bamboo piece is relatively soft and the strength is relatively poor, it cannot be used for a long time, and after pulling for a while, some of the small sawtooth is broken, and some become dull, and the bamboo piece needs to be replaced. This affects the speed at which trees are cut down, and using too many pieces of bamboo is also a big waste. It seems that bamboo chips should not be used as a material for making sawtooth, and a material with high strength and hardness should be found to replace it, and then Lu Ban thought of iron sheets.

So they immediately descended the mountain, and the blacksmiths helped to make iron pieces with small serrations, and then went to the mountain to continue their practice. Lu Ban and his apprentice each pulled one end and pulled it up on a tree, only to see them go back and forth, and after a while, the tree was sawn off, quickly and labor-saving, and the saw was invented.

1。From the annoying flies, a very peculiar small gas analyzer was successfully imitated. It has been installed in the cockpit of a spacecraft to detect the composition of the gases in the cabin.

2。From fireflies to artificial cold light;

3。Electric fish with volt batteries;

4。The downwind ears of jellyfish, imitating the structure and function of jellyfish ears, designed the jellyfish ear storm instrument, which can predict the storm 15 hours in advance, which is of great significance to the safety of navigation and fishery.

5。According to the visual principle of frog eyes, people have successfully developed an electronic frog eye. This electronic frog eye can identify objects of a specific shape with the same accuracy as a real frog eye.

After the electronic frog eye is installed in the radar system, the anti-jamming ability of the radar is greatly improved. This radar system can quickly and accurately identify specific shapes of aircraft, ships, missiles, etc. In particular, it can distinguish between real and fake missiles and prevent the real from being confused with the real.

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 can issue an alarm if it detects that the aircraft is about to collide. In the traffic arteries, it can direct the driving of vehicles and prevent the occurrence of vehicle collisions.

6。According to the principle of the bat ultrasound locator, people also imitated the "pathfinder" for the blind. This pathfinder is equipped with an ultrasonic emitter that a blind person can carry to spot people on electric poles, steps, bridges, etc. Today, "ultrasound glasses" with a similar effect have also been made.

7。An incomplete photosynthesizer that mimics cyanobacteria will be designed to bionic photolyzed water, so that a large amount of hydrogen can be obtained.

8。Based on the study of the human skeletal muscular system and bioelectric control, a human augmenter - a walking machine has been imitated.

9。The hooks of modern cranes originated from the paws of many animals.

10。The roof corrugated roof mimics the scale armor of animals.

11。The oars are modeled after the webbing of a duck.

12。The saw learns the mantis arm, or sawgrass.

13。Xanthium was inspired to invent Velcro.

14。Lobsters with a keen sense of smell provide ideas for people to make odor detectors.

15。Gecko toes offer an encouraging prospect for creating adhesive tapes that can be used over and over again.

16。The colloids produced by shellfish from their proteins are so strong that they can be used for everything from surgical sutures to ship repairs.

16.The arrangement of the foliage and the construction of the Grand Theatre of Sydney.

17.The ups and downs of submarines and fish.

18.Sidewinder and air-to-air Sidewinder missiles.

Humans discovered from bats that they could not touch extremely thin wires at night, and invented radar for airplanes.

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 oars to imitate fins. Legend has it that as early as the Yu period, the ancient working people of our country observed the fish swimming and turning with the swing of their tails in the water, and they set up wooden oars on the stern of the boat. Through repeated observation, imitation and practice, it was gradually changed to an oar and rudder, which increased the power of the ship and mastered the means of making the ship turn.

In this way, people can make boats sail freely, even in rough rivers.

The wings of flies (also known as balance sticks) are "natural navigators", and people imitate them to make "vibrating gyroscopes". This instrument is already being used in rockets and high-speed aircraft, and it has achieved autonomous driving.

The fly's eye is a kind of "compound eye", which is composed of more than 30o0 small eyes, and people imitate it to make a "fly's eye lens". The "fly's eye lens" is made of hundreds or thousands of small lenses neatly arranged and combined, and it can be used as a lens to make a "fly's eye camera", which can take thousands of identical photos at a time. These cameras have been used for printing plates and for mass copying of tiny circuits of electronic computers, greatly improving ergonomics and quality.

The "fly's eye lens" is a new type of optical component, and it has many uses.

The wings of birds have many special functions and structures, which make them not only good at flying, but also perform many "stunts", which are difficult to achieve with current human technology. The tiny hummingbird is the "***" of birds, it can both take off and land vertically, and it can fly backwards. While sucking nectar, it does not rest on the flower like a bee, but hovers in the air.

What a clever flight. The creation of a vertical take-off and landing aircraft with the characteristics of the Hummingbird flight has become a dream dream of many aircraft designers.

Many biomimicries in the military field were invented by inspiration from nature.
