There are many human inventions, which ones are very interesting?

As the rulers of the earth, we humans will not only take advantage of what exists on the earth, but also learn the strengths of various animals, which will be used to strengthen ourselves and bring convenience and pleasure to our lives.

In my personal opinion, the following inventions of human beings are very interesting and full of wisdom

1. Bamboo Dragonfly Bamboo Dragonfly is a kind of children's toy that we all played with when we were children, because its production method is very simple, and the gameplay is also very simple. The most important point is that the cost of bamboo dragonflies is low, so everyone played with it when they were young.

It is a very interesting children's toy, and many times it can fly very high and long distances with just a gentle rub of both hands, like a propeller.

The bamboo dragonfly is modeled after the wings of the dragonfly, and his principle has also been applied to ***. It is a simple, very practical and interesting invention.

2. In addition to bamboo dragonflies, the itch catcher is also a very remarkable and interesting invention of our human beings. Each of us will have a place to reach our bodies.

In many cases, if there is itching, and the location of the itching is out of our reach, it will make people feel very embarrassed.

And the appearance of the itch grabber solves this problem perfectly. Not only does it make us scratch all over our body, but it also gives us new sensations.

When I was a child, I was very curious and fond of tickles, and often played with him as a toy. also because of his playfulness, he was not scolded by his parents.

3. SwimsuitI think swimsuit is also a very interesting invention of our human beings, and the invention of swimsuit is also very remarkable. When we saw frogs swimming, we used the characteristic of frogs to invent swimsuits suitable for us humans.

Especially for women's swimsuits, not only waterproof is particularly good, but also particularly slim, which is one of the favorite items of many girls.

In the history of human development, there are many interesting inventions similar to these; And the most interesting thing for me is the tickler.

There are many interesting inventions, such as the discovery and determination of DNA, which can be used in the detection of criminal cases, which Watson never imagined at the time, and how many people he has helped save with this discovery.

For example, humans imitated fish gills and invented artificial gills to breathe in water, a crib rocking chair, which is fun for children and convenient for adults, and a mobile phone holder that is convenient for charging on the wall and a portable fish tank, which is very helpful for people who like fishing.

Cell phone. When the mobile phone realizes the presence of the whole world and the north of the world, and realizes the charm of idealism, it creates fireworks on the busy road.

Human Inventions:

1. Internet.

The Internet is not very recent, but that doesn't mean it's any less important to our society today than inventions with a long history. The internet originated in the 1970s with the development of various communication networks and has become very popular since then. The Internet allows information to be disseminated around the world more quickly and efficiently.

The advent of the Internet has profoundly changed the world and will always be an important part of our social life.

2. Anesthetic. I don't know how you are, but most people can't mentally tolerate surgery without anesthetics.

Target. Anesthetics allow patients to perform surgical procedures without experiencing the horror of pain. Now, anesthetics are being replaced by a number of other methods, including gas hypnosis. But that doesn't erase the enormous contribution of narcotics to our society.

3. Printing.

Speaking of which, you may not want to believe it, before the invention of printing, all books were written by hand. For those of us who were born surrounded by all kinds of printing, computer printing, and so on, it's hard to understand how difficult and inefficient copying a book can be. The advent of the printing press made it possible for humans to exchange ideas and information more quickly.

It is precisely in this way that our wealth of knowledge has been rapidly accumulated and developed, and has created the glory of mankind today.

4. Various tools.

Basically, tools have become a very important part of our society. It allows us to build things from scratch and use tools to repair them when they break. Tools enable us to turn imaginary things into real things.

You can imagine a society without tools: all the technology we see will cease to exist.

5. Language. Of all the inventions of mankind, language deserves to be ranked first. Humans create language to better communicate thoughts and emotions with others.

The ability to communicate with each other with precision and efficiency is the basis for humans to create all kinds of amazing technologies. Although some animals do communicate with each other, their communication is simple and inefficient. No one knows how or by whom the oldest languages were, but one thing is certain – language is humanity's greatest invention.

Big Turtle Back Little Turtle: A tank with a turret turned.

Birds fly in the sky: all kinds of flying machines are made.

Honey bee nest building: a variety of regular hexagonal honeycomb structure plates.

At the end of each dragonfly's wing, there is a thicker spot that is slightly heavier than the surrounding area, which is the key to preventing the wings from trembling. Aircraft designers studied the flight methods of flies, mosquitoes, bees, etc., and created many new aircraft with various excellent performances.

Whale: The shape is an ideal "streamliner", and the "streamliner" has the least resistance in the water. Later, engineers imitated (fǎng) the shape of the whale and improved the design of the hull, which greatly increased the speed of the ship.

Eggshell: Able to evenly distribute the pressure (yún) to all parts of the eggshell. Based on the characteristics of this "thin shell structure", the architect designed many buildings that were both light and economical.

Kangaroo: Off-road car that can jump, Shell: Tank ...... with a sturdy shell

Fish swim in the water: learned to swim, invented submarines.

One-piece shark suit: The first generation shark suit imitated the shark's **, and some rough tooth-like protrusions were designed on the swimsuit to effectively guide the water flow and tighten the body to avoid the quiver of ** and muscle digging flesh. The second generation of the Shark Suit adds some new highlights, adding a material called "elastic**", which can reduce the resistance of a person in the water by 4%.

In addition, two attachments have been added, and a bumper made of titanium silicone resin attaches to the forearm to make it easier for the athlete to swim; A vibration control system attached to the chest and back of the shoulders helps direct the flow of water.

Seeing the light for the blind: After implanting a tiny bionic retina, 3 blind patients not only saw the light that went on or off, but even managed to distinguish between a cup and a plate with their eyes.

Synthetic spider silk: Spider silk contains a fibrin protein similar to the keratin found in hair and horns. This protein is secreted and begins to become tough. By delicately balancing the water content, spiders and silkworms can prevent fibrin from curing too quickly.

Neuronal function simulation device for direction of motion recognition.

Automatic target reporting machine.

Flat type compound eye lens.

Side suppresses low-light TV.

Dragonfly - airplane;

Downwind ear - **;

Frog — Fast Scanning System.

Flies - odor detectors.

Praying mantis — scythe.

Flies and spaceships.

Fly sniffer: small gas analyzer.

From fireflies to artificial cold light. Since this light has no power source and does not generate a magnetic field, it can be illuminated by a biological light source to remove magnetic mines.

Electric fish with volt batteries. After the anatomical study of the electric fish, it was found that there is a peculiar power generation organ in the electric fish. The Italian physicist Volt designed the world's first voltaic battery based on the electric fish power generation organ as a model.

Jellyfish Ears: Jellyfish Ear Storm Instrument, which is simulated fairly accurately.

I want to say to mankind: it is invention that promotes social progress and brings happiness to mankind, and the deep meaning of creation lies in the potential vitality of the whole society, promoting scientific and technological progress, inspiring and motivating people's wisdom and talent, improving the spiritual and material civilization level of all mankind, and enabling the country to increase its technological competitiveness (technology output), enhance its national strength, and make the people happy.

The tremendous role of invention and creation can be most directly and clearly reflected through economic development and its benefits. Successful inventions can create great economic benefits.

On the contrary, if a country is not creative, the country will not have vitality, the nation will lose hope, mankind will lose confidence, and the whole society will stand still.

Most of the things you have invented still have some shortcomings, and you have to continue to improve.

Too many inventions are also damaging to the environment.

Human beings have the smartest brains, the wisest minds.

I don't know! I don't know about wow.

Yes! If you hadn't invented these things, we wouldn't have lived so well!
