Ruban invented the shovel?

Joseph Camden: Condoms.

Condom is called condom in English vocabulary. It is named after its inventor JosephCondom, a British doctor in the late 7th century. Condom The condom invented is made of the caecum of lamb. First, cut the sheep intestines into appropriate lengths, dry them in the sun, and then soften them with oil and wheat bran until they become thin and elastic.

Because Kant invented the condom and was knighted by King charles ii of England, his invention was praised as a "pleasant invention" by Chinese people.

However, historical data show that Kant is not the originator of condoms, because similar "love tools" are depicted in ancient Egyptian and Roman works of art. This earliest condom was made of animal bladder or swim bladder.

As early as 2000 BC, condoms appeared in the lives of ancient Egyptians. At that time, it was called * * * set. Their function is not to prevent diseases and contraception. Like jewelry worn by women, they are used as decorations, and men usually hang them on their bodies, which is a symbol of wealth and status.

Ancient myths about the origin of condoms: ancient dynasty and legendary animal intestinal membrane and bladder condoms In 3000 BC, Minos, king of Crete island, was the inventor of condoms. It is said that the king abandoned his wife, and her wife cast a spell on it: as long as the king shoots * * * at the woman with him, these * * * will become vicious people and kill this woman. In this way, for a long time, King Minos dared not go near women. Later, he found that before having sex, the goat's bladder was placed in the mistress's * * *, and the tragedy would not happen again. So condoms were born.

Family planning was not invented by China. In BC 1332, Pharaoh made condoms from camel skin. In order to make princesses of noble birth have more children, princesses of humble birth have fewer or no children, so as to ensure the noble lineage of royal descendants. After more than two hours' visit, I got a general understanding of Egyptian civilization, which was earlier than China in many aspects.

Contraceptive devices were also recorded in ancient Egypt 19 dynasty (BC 1350- 1200). Contraceptive devices can be found in archaeological excavations, but I don't know whether they are used for * * * or sacrifice. This kind of condom is made of animal intestinal membrane or bladder, and is also used to decorate male genitals. This decoration can be found on the male corpse in the tomb.

The best way to prevent sexually transmitted diseases and AIDS is to stay single, avoid premarital and extramarital sex, and consciously resist drug abuse.

The composition invented a thing.

Science is more and more developed and doors are more and more advanced, but there are still many shortcomings in the current security door, so I want to design a unique security door to benefit the people.

The shape of the security door I designed is the same as that of the robot. The robot's eyes are the "cat's eyes" we used to look at people at the front door, and the robot's hands are the handles of the front door. He uses a fingerprint smart board.

The robot's mouth is used to talk to the outside world, and there is a microcomputer in it to control the smart board.

People who are tired from work will be very happy when they get home and stand in front of their homes. The first thing they saw was the cute appearance of the robot.

The interior of the security door I designed is controlled by high-tech passwords.

The head of the machine, like the mainframe of the computer, controls the whole robot body.

The fingerprint input by the smart board and the memory of the microcomputer are controlled by his head.

When the master comes back, first of all, the robot's eyes will bend and its mouth will smile and say "hello!" " Three times. When the owner presses the smart board with his thumb, the microcomputer will make a judgment immediately.

Open the door in one second.

If a thief comes, presses his fingerprint, and the microcomputer finds that something is wrong, the door will open hard, bump the thief into the corner, and then recover within one second.

I designed the security door and information system.

When the host is not at home and a guest visits, if the guest wants to leave a message, he can dial the phone number of the host on the robot foot, and a smart board will appear inside, so that the guest can write what he wants to say and restore to the original state.

When the master comes back, as long as he presses his fingerprint, the robot's mouth will tell the master the content of the message.

If the guest and the host want to buy something and leave, and the guest has something urgent to go out, the guest can come out by pressing the nose of the robot.

Learn a 320-word composition about what I want to invent most.

I want to invent an environmental protection robot "stinks!" So much rubbish! " "Why is there so much smoke? I can't walk there! " "Ah, several.

""ah! The children are sick ... "People are talking about it. It seems that the dirty and smelly environment is really harmful to people.

Ha ha! No problem, on the environmental robot.

It has red and blue buttons on its head and red and blue small backpack on its back. If you press the red button, you will put the garbage within 10 meters around the robot into the red backpack. If you press the blue button, you can collect all the air smoke around the robot in the blue backpack 10 meter. You must think, what if the backpack is full? Don't worry, there is a thin and long needle in the center of the robot's head. Don't underestimate this needle, it uses it to remove waste! It can turn all waste into dense trees, fragrant flowers, or clear rivers and green grasslands.

Those small and exquisite eyes-they scare you, they can emit a special kind of light, which can destroy bacteria within100000 kilometers around the robot at once.

It has many thorns on its stomach, so it can spray fragrance from time to time to make the air fresh.

Oh! I forgot to mention that there is something called a vacuum tube on my hands, which can "swallow" the exhaust gas from the rear of the car and then "eat" it to turn this gas into electricity.

And its feet, where you have stepped, will be clean without any stains.

How about an environmentally friendly robot that brings comfort to people's lives?

I want to invent something through animals.

Scientists have invented many things from animals and plants! I also want to learn from scientists.

Gecko's hands and feet are very attractive. It can easily climb the wall without falling.

I want to design a kind of shoes like gecko's hands and feet. The name of this kind of shoes is "Invincible Suction".

Very convenient. Workers don't need to bring ladders when painting walls. They just need a pair of shoes with "invincible attraction" to start work. It can not only absorb energy, but also reduce your weight. Even if you paint the wall upside down, it won't fall off. There are two buttons on the right side of the shoes. Press the green button, it will let you move up and down on the wall without falling off. Press the red button to get off.

Is it convenient for you? When I really invented "invincible suction", I will definitely give it to those workers who wash the ground and build houses.

Nature is really a good teacher for human beings. I will carefully observe the things around me and design more gadgets.

Observe a creature and invent a thing.

The contribution of birds to mankind is well known. Birds also have a special function, which is to inspire human wisdom and provide principles and blueprints for human beings to explore ideal technical devices or vehicles. It can be said that birds are human teachers in structure, function and communication, and scientists often need to ask birds many modern scientific and technological questions. Eagles hit the sky, pigeons fly thousands of miles, and birds can fly freely in the air, which is good for human beings. According to legend, more than 2,000 years ago, China famous craftsman Lu Ban studied and made wooden birds. According to historical records, in China more than 900 years ago, bird feathers were tied together to make wings, which could glide 100. More than 400 years ago, Italian Leonardo da Vinci designed a flapping-wing machine based on his observation and research on birds, trying to fly with the help of pedal movement. Only when people understand the gliding mechanism of birds' fixed wings do they realize that the wings must be as thick as birds' wings and the trailing edge is thin, so as to form a curved surface and generate lift. In addition, the industry provided light metal materials and high-power engines, and finally the airplane was invented in 1903, which realized the ideal that human beings longed to fly into the sky for thousands of years. Ever since man invented the airplane and flew into the sky, he has been constantly innovating the airplane. No matter its size, load and speed, it has rapidly surpassed that of birds. Modern aircraft fly faster, farther and higher than any bird, especially in recent years, which can sail between stars, which birds can't reach. Nevertheless, in some flying techniques and aircraft structures, man-made aircraft are still not as perfect and exquisite as birds, not to mention energy consumption. For example, the golden pheasant can fly over the ocean for more than 4000 kilometers continuously, but it only loses 60 grams. If the plane can fly at this efficiency, it will save a lot of fuel. Birds' wings have many special functions and structures, which make them not only good at flying, but also perform many "stunts" that human technology is still difficult to achieve. Hummingbird is a "helicopter" among birds and can take off and land vertically. You can fly backwards. When sucking nectar, it does not stop on the flower like a bee, but hovers in the air. What a clever flight. It has become the dream of many aircraft designers to build a vertical take-off and landing aircraft with hummingbird flight characteristics.

Elementary school composition: what I want to invent?

Topic: "The Robot I Want to Invent" With the development of science and technology, robots in the future will more and more help humans accomplish tasks that humans cannot accomplish themselves.

Nowadays, with the improvement of people's living standards, excess nutrients such as fat accumulate in people's blood vessels. After a long time, just like the silt in the river, people's blood vessels become narrower and narrower, and some even become completely blocked.

In this way, with the above situation, people's blood pressure will rise, and some even have blood vessels blocked.

Because of high blood pressure, some capillaries in hair are broken, and bleeding spots occur in the brain, which will threaten people's lives.

Because the brain is the nerve center of human beings, once the cranial nerves are oppressed by cerebrovascular hemorrhage, it will be life-threatening if it is not treated in time.

Some patients may suffer from the sequelae of falling into the lower body even if they are treated in time.

Therefore, in the future, I want to invent a very, very small robot, which can go deep into every capillary of people, just like excavators and bulldozers dredging rivers, to clean people's blood vessels, and it will thoroughly clean blood vessels and waste on their walls.

As long as people regularly use the robot I invented to clean blood vessels, then his or her blood vessels can be unobstructed at all times.

Therefore, in the future, people will no longer have to stay away from their favorite foods such as braised pork because of cardiovascular and cerebrovascular diseases.

That's not all this robot can do. It can also reach every part of the human body and send back the image of that part that the doctor wants in real time. Is it much more convenient than the current X-ray machine? What's more commendable is that this robot can also clean up a lot of fat accumulated in the human body, and those women who love beauty no longer need to take diet pills or even fast in order to lose weight.

As long as I use the robot I invented, women who love beauty can always keep slim and eat whatever they want, and no longer have to worry about obesity caused by overnutrition! How's it going? Is the robot I want to invent capable? Are you excited? Come and find me!

I want to invent a composition of about 300 words.

I am a person who wants to be an inventor when I grow up. I want to invent a door when I grow up. The name of this door is "Universal Door". The purpose of the universal door is to open it with a key. If you forget your key, you can open it with your fingerprint. If your hand is rotten, you can open it with a password. If you forget your password, you can open it with a card. If you forget your card, you can also open it with ultrasound.

If there is a thief's universal door, it can also automatically call the police, and an iron fist will be stretched out next to it to beat the thief. After the fight, an iron net will pop up to catch the thief and wait for the police to catch it.

I also want to invent a robot that can help you cook, wash clothes and buy food ... If you are sick, it will automatically dial 120.

If there is a thief, he will call the police, he will fight with the thief ... he will also accompany you to play chess, do sports and practice martial arts ... I like inventing things very much and envy scientists and inventors.

Refer to it and adopt it. ...

Imagine a composition. One thing I want to invent is 300 words. Why?

I want to invent an all-around car, because there are cyclists, motorcyclists and motorists, but it is inconvenient to ride two bicycles. Riding a motorcycle or driving a car will pollute the environment, so I want to invent an all-around car.

Its structure is very special, colorful outside, shaped like a tiger, and there is no wheel, and the position of the lamp is different, only one position, but it is very long, more than one meter, more than four meters.

The steering wheel is very light, as long as you turn it where you want to go.

Just say stop and the brakes will stop immediately.

It doesn't have a stereo, but it has a GPS to help you navigate.

In case of an earthquake or tsunami, it will suddenly turn into an airplane or a transformer, so that you can avoid disaster.

If there is such an all-around car, I want to buy one for the whole universe and the whole earth.

Get inspiration from animals and invent a little thing. .

Nature is the teacher of mankind. For example, people observed thatch and invented saws. For example, people observed birds and invented airplanes.

I saw a gecko once.

One day, I went to the Pearl Park to play, and my good friend and I were in a good mood. I wanted him to see the "rain of leaves", so I reached out to the fence covered with vines and "wow" picked many leaves. I was just about to open a "split flower" when I suddenly found something soft and brown in the leaves. I thought: it won't be the kind that bites people, and it will also seal my throat with blood. But my curiosity drove me to catch the little thing with both hands, and a big stone fell to the ground at a glance.

I heard that the gecko's tail will grow when it is broken, so I took it home, cut it in half with a knife, put it in a beautiful moon cake box and fed it some water. When I looked at its cut tail, I found it was still moving.

I hurried to see the gecko. I saw gecko crawling on the wall! I grabbed it and two questions flashed through my mind. 1. Why does the gecko move when it is broken? 2. Why can the gecko climb the wall? Later, I checked the encyclopedia, only to know that the gecko's broken tail can still beat with nerves.

3. The fingers and toes on the four corners of the gecko are flat and wide.

There are skin folds under the toes and fine glandular hairs on them, so they have strong adhesion and can crawl on walls and ceilings.

I want to use the special ability of gecko to walk on walls and ceilings to invent a thing-gecko foot crawler: now some explorers go to some steep mountains, and if they are not careful, they will fall down and be seriously injured. Put on the gecko foot crawler, the explorer can walk up the mountain like walking on the flat ground.

I hope this gecko climber can be made with the development of science and technology.

Nature is like a kaleidoscope. As long as you can observe every plant carefully, every animal will make new discoveries.

Get some inspiration from a person and invent something. The composition is not less than 660 words.

I also want to learn from scientists, get inspiration from animals and plants and design small inventions.

Nature is the teacher of human beings, and scientists get a lot of inspiration from animals and plants.

For example, in the past, the TV tower was not strong, and the strong wind could fly 80 meters a second. In a wind like this, the TV tower may be blown down. People got inspiration from the fir tree and built the TV tower into the shape of a fir tree. That would be great. Rain or wind, the TV tower will not fall down. Scientists were also inspired by shark skin and invented swimsuits, which reduced the resistance of water ... I also want to learn from scientists, get inspiration from animals and plants and design small inventions.

Gecko's hands and feet are very attractive. It can easily climb the wall without falling.

I want to design a kind of shoes like gecko's hands and feet. The name of this kind of shoes is "Invincible Suction".

Very convenient. Workers don't need to bring ladders when painting walls. They just need a pair of shoes with "invincible attraction" to start work. It can not only absorb energy, but also reduce your weight. Even if you paint the wall upside down, it won't fall off. There are two buttons on the right side of the shoes. Press the green button, it will let you move up and down on the wall without falling off. Press the red button to get off.

Is it convenient for you? When I really invented "invincible suction", I will definitely give it to those workers who wash the ground and build houses.

Nature is really a good teacher for human beings. I will carefully observe the things around me and design more gadgets.

The account is closed, so simply write the beginning and the end.

A 300-word composition describing things created according to the imagination of animals and plants.

Since ancient times, nature has been the source of various scientific and technological principles and major inventions of mankind.

There are many kinds of animals, plants and substances in the biological world. In the long process of evolution, in order to survive and develop, they gradually have the ability to adapt to changes in nature.

Humans live in nature and are "neighbors" with the surrounding creatures. The peculiar abilities of these creatures attract people to imagine and imitate.

Using their own abilities of observation, thinking and design, human beings began to imitate biology, and made simple tools through creative labor, thus enhancing their ability and ability to fight against nature.

The earliest tools used by human beings-wooden sticks and stone axes-are undoubtedly natural wooden sticks and natural stones; The use of bone needles is undoubtedly an imitation of fish bones ... The creation of all these tools and the choice of lifestyle cannot be said to be imaginary by human beings, but can only be said to be a direct simulation of substances and certain forms existing in nature. It is the primary creative stage of human beings, and it can also be said that it is the origin and embryonic form of bionic design. Although they are rough and superficial, they are the foundation of our development today.

In our country, there have long been examples of imitating creatures.

According to legend, in more than 3000 BC, our ancestor Youchao imitated birds to build nests in trees to prevent the harm of wild animals. More than 4000 years ago, our ancestors "turned into cars when they saw the flying canopy", that is, they invented wheels when they saw the flying canopy rotating with the wind and made cars with wheels.

The architecture of the mountain gate in front of the main hall of an ancient temple looks like an elephant in terms of its architectural structure. The pillar is round and thick, like an elephant's leg.

The industrious and brave working people in ancient China had long had all kinds of wonderful fantasies about the blue sea, the blue sky and the soaring goshawk.

According to the historical records of Qin and Han dynasties, more than two thousand years ago, our people invented kites and applied them to military liaison.

During the Spring and Autumn Period and the Warring States Period, Lu Ban, a craftsman of the State of Lu, first began to develop flying wooden birds. He was inspired by a kind of toothed grass blade that can cut the skin and invented the saw.

According to Du Yang Miscellaneous Magazine, there was a Han Chinese He Zhi in the Tang Dynasty. "He is good at carving wood for sex, cranes, crows and magpies. Drinking and pecking people is no different from the truth. When he is locked in the abdomen, his hair will fly, but it can be as high as three feet to one hundred feet away, but it will only start. "

During the Western Han Dynasty, some people made wings out of bird feathers and flew down from a high platform in an attempt to imitate the flight of birds.

The above cases are enough to show that the working people in ancient China had carefully observed and studied the flapping and flying of birds, which was also one of the earliest bionic design activities.

The invention of a rocket weapon "Shenhuo Flying Crow" in Ming Dynasty also reflected people's desire to learn from birds.

The imitation of aquatic animals-fish by the working people in ancient China was also fruitful.

The ancients gained the freedom of water transportation by imitating fish living in water, cutting down trees and chiseling boats, making fish-shaped hulls out of wood, and using fish pectoral fins and caudal fins to paddle and paddle.

Later, with the improvement of the production level, the dragon boat appeared, which was influenced by many animal shapes.

The rocket weapon "Fire Dragon Out of the Water" used in ancient water wars somewhat imitated the meaning of animals.

The above examples show that the early bionic design activities of the working people in ancient China created extraordinary achievements for the development of China's splendid ancient civilization.

In the history of foreign civilization, it has also experienced a similar process.

In ancient Greek mythology with rich production knowledge, some people made wings out of feathers and wax and escaped from the maze; Thiel invented the saw, which is said to be inspired by the shape of the fish's back bone and the snake's palate bone.

/kloc-In the 5th century, German astronomer Miller made iron flies and mechanical eagles and performed an air show.

/kloc-around 0/806, Kelly, a British scientist and one of the founders of aerodynamics, imitated the spindle shape of trout and groundhog and found a streamlined structure with low resistance.

Kelly also designed a wing curve that imitated the wings of birds, which greatly promoted the birth of aviation technology.

At the same time, French physiologist Maret made a detailed study on the flight of birds. In the book Animal Machines, he introduced the relationship between the weight of birds and the area of their wings.

Helmholtz, a German, also found that the weight of flying animals is directly proportional to the cubic of body linearity when studying flying animals.

Helmholtz's research pointed out the limitations of the size of flying objects.

Through the detailed study and careful imitation of bird flying organs, according to the principle of bird flying mechanism, people finally made a glider capable of manned flight.

Later, the designer designed the boom of the excavator according to the posture of the crane. During World War I, people got inspiration from the wild boar who survived the gas war and designed a gas mask by imitating the nose of the wild boar.

What is the principle of a submarine that floats and sinks flexibly in the ocean? Although we have no evidence to investigate whether the submarine designer consulted the opinions of the biological community when designing the submarine, it is not difficult to imagine that the designer must know that the swim bladder is an important organ used by fish to change the proportion of their bodies with the water so as to rise and fall in the water.

Frogs are amphibians. Sports workers carefully studied the frog's movement posture in the water and summed up a set of labor-saving and fast swimming movements-breaststroke.

In addition, the fins made for divers are almost completely made according to the shape of frog hind limbs, which greatly improves the diver's ability to move in the water.

Second, the history of bionic design Since ancient times, nature has been the source of various scientific and technological principles and major inventions of mankind.

There are many kinds of animals, plants and substances in the biological world. In the long process of evolution, in order to survive and develop, they gradually have the ability to adapt to changes in nature.

Humans live in nature and are "neighbors" with the surrounding creatures. The peculiar abilities of these creatures attract people to imagine and imitate.

Using their own abilities of observation, thinking and design, human beings began to imitate biology, and made simple tools through creative labor, thus enhancing their ability and ability to fight against nature.

The earliest tools used by human beings-wooden sticks and stone axes-are undoubtedly natural wooden sticks and natural stones; The use of bone needles is undoubtedly an imitation of fish bones ... The creation of all these tools and the choice of lifestyle cannot be said to be imagined by human beings, but can only be based on the material and nature. ...
