The brilliant inventions of mankind

Wheels, buttons, spoons and discs are important inventions of human society. They mostly originated in ancient times and evolved to this day.

The greatest inventions of mankind

 

The wheel is one of the most important inventions of mankind, greatly improving production and transport as well as many other aspects of human life. When was the wheel born? So far, it is still a big question for historians. Archaeologists found the oldest wheel in Mesopotamia dating back about 3,500 BC. On the ancient Sumerian paintings, there is a depiction of a truck with a round wooden saw from the trunk.

The first spokes wheel was created on the Asia Minor Peninsula (now in Turkey) about 2,000 BC and was immediately introduced to Europe and China and India through the drivers. love. This type of wheel is mainly used in passenger vehicles, especially Egyptians use to transport goods and construction materials. Wheels are widely used in ancient Greece and later in ancient Rome. In the Americas, wheels were introduced by European navigators when they found America.

Shirt button

In ancient times, our ancestors knew how to make jute and bark fibers, and they used animal bones and thorns instead of buttons. Ancient Egyptians and Romans cut holes on one end of a cloth used to make clothes and then put the other end over, or tie a knot. Chinese people use the drawstring for centuries.

Nobody knew the buttons that were invented by anyone. Some historians claim buttons from Roman times, others claim that from ancient Greece, while another group of scientists gave evidence of the Asian origin of the buttons.

The first daisies were put into use in the 8th century and until the 18th century, buttons were considered luxury items that only rich people dared to use. The King of God uses daisies in gold and silver. Rich people use elephant bones as daisies. And ordinary people still tie knot, or use drawstring. In the early 18th century, Europeans began producing daisies in steel and copper. By the end of the nineteenth century, buttons were still expensive, so when people sewed new clothes, they often unbuttoned their old shirts.

 

About 3,000 years ago, a king devised a way to protect himself from being infected with venereal diseases while going "sexually" . He used fish balloons in the relationship.

The word "condoms" was born in the 17th century, when the then King Carl II's medical officer, Condom, came up with a way to improve the bag to help the king prevent birth want and avoid venereal disease when having sex with girls. The yogi used a sheep intestine to cut the thin section and sew one end into a bag for the King to use. Later people also learn this method, but using sheep intestines is also quite expensive, so people often dried to reuse a few more times.

By 1839, vulcanizing technology was born, allowing the production of crude rubber into a new form of material - refined rubber, with good resilience. This technology makes a great revolution for condoms. In 1844, the first type of rubber bag was born and in 1919 latex was used to make condoms. This type of material has very good elasticity, can be rolled very thin and does not smell rubber. This type of condom is used to this day.

In ancient times people had many ways to create fire. From rubbing two bark trees into each other for hours until the fire, until the way to use flint to hit each other . Then when creating the fire, it is necessary to maintain the fire quite elaborately.

In 1830, 19-year-old French chemist Charles Soria invented phosphorus matches, made from a mixture of bertollete salt, white phosphorus and glue. This type of match is easy to use, when rubbed with any hard surface it can emit fire. So in many films we often see cowboys matches matches on the heels to light cigarettes. Phosphorus does not have an unpleasant odor, but is harmful to health because white phosphorus contains harmful toxins.

By 1855, chemist Johan Lunstrom did an experiment with red phosphorus, and he applied a thin layer of this substance to the surface of sandpaper. As a result, he created a new type of ignition that is easy to ignite and less harmful to user health. This is the match we are using today.

 

Ancient Romans used a brush with a handle to do personal hygiene after defecating. The brush is then soaked in salt water jar for further use. The Vikings wiped with a towel, while the Native Americans used the leaves within reach, or corn cobs. The French kings were more advanced, they used cloth rags.

Chinese people pioneered the use of personal toilet paper. But only the emperor is allowed to use it. Until later, when printing techniques developed, new paper was widely used for personal hygiene (old newspaper, old books .).

In 1857, an American named Joseph Hayetti devised a way to cut paper into squares and pack it. He is very proud of his creativity and has printed his name on each sheet of paper. It is not clear who later thought of a way to curl up toilet paper like today, only to know that in 1890 the paper "Scott Paper" in the United States produced this kind of toilet paper in bulk.

Invent

People know how to sew for more than 20,000 years. Prehistoric people skinned animals, sewing them with rudimentary tools such as thorns and sharp stones. They punched holes in the tools and the animal string to sew the clothes. Archaeologists have found animal or stone needles in excavations dating to 17,000 years in Western Europe and Central Asia. In Africa, humans used coconut veins as needles and dried plant fibers.

The first metal sewing needle was made in China and it was also in this country, in the 3rd century BC, humans created the stitching. These inventions were then brought to Europe through merchants.

The first scissors were made by the ancient Egyptians in the 16th century BC. However, it was made from a continuous metal plate, not two metal bars crossing each other. The type of scissors we use today is created by Leonardo da Vinci.

Spoons, forks and knives

Since ancient Rome, humans have used many sophisticated ceramic dishes for meals. But they ate. The first spoons were invented and used up to 5,000 years ago. Mesopotamia people know how to shape clay into a small shell to scoop up food. The first metal spoon was made of silver by the Russian King Vla-di-mia.

As for plates, around the 10th century in Asia, there appeared a kind of dinnerware with the appearance of a plate, but there were many teeth, which looked like a scratching table of Tram Bat Gioi. A hundred years later, the invention was introduced into Europe and by the 16th century, the plate was widely used and shaped almost like today, with two pointed teeth used to stab food.

By the end of the 18th century, large and long knives such as the machete which were used to cut food were replaced by compact knives and round curved noses. The reason for this improvement is simple: there is no longer a need for sharp and long knives to stab the food because there is a plate to perform this function.

Invent

From the Stone Age, people began to have unique creative inventions to solve women's monthly problems, using dried grass, dried leaves, and even seaweed. The ancient Egyptians created a type of sanitary napkin that today is called tampone, however in Egypt that day the tampone was made of sedge. The ancient Greeks improved tampone, using a cloth wrapped around a small stick. In ancient Rome, women used silk cloth to make sanitary napkins, in Japan they used paper, while African women used dry grass bundles for cleaning.

By the beginning of the 19th century, people began to use old mop rags stitched into small bags, inside stuffed. These advanced sanitary pads are washed, dried and used again and again. At the end of the 19th century, there was once a European enterprise producing a wide range of these sanitary napkins, but due to not advertising, this production line failed.

In the early 20th century, women began to use curtain fabric, bucket cloth. In the 1920s, curtain-type sanitary napkins began to be sold at department stores and magazine ads. This type of sanitary pad is attached to the underwear with a bandage, or connected to the waistband on the waist.

 

5,000 years ago, people knew how to take care of their gums. At the Egyptian archaeological sites, scientists found ancient toothbrushes, made from branches with silk thread at the top.

However, it was not until 1498 that Emperor Hoang Tri Minh (China) created the type of brush we use today. Hoang Tri's toothbrush is made from animal bones, and the brushed tooth is made from Siberian wild boar feathers.

In 1937, humans invented nylon. A year later, the brush began to be made of plastic nylon fibers, but it was not popular because the nylon fibers were quite hard at the time, easily damaging the gums. Wild boar feathers are softer, so they continue to be used until the middle of the 20th century.
