How did cavemen make their tools?

According to scientists, prehistoric people who lived about 300 years ago were cave dwellers. Their main occupation was hunting. Everyone made his own tools and implements. With a stone mallet, he smashed the cobblestones so that they became the right size for hunting. The result was a hammer, one end of which was slightly pointed. It was used for digging, scraping, hewing or cutting. Another widely used tool then was the hand axe. It was on a heavy handle and sharpened on both sides. It was used for various purposes, such as digging up roots, cracking nuts, or slaughtering and skinning animals.

The Neanderthals, who lived 150 to 000 years ago, were also cave dwellers. In addition to the hand axe, the Neanderthal had pointed tools. They were skillfully made of flint and had a sharp end. Some of them were in the shape of a trihedron. Some pointed tools had one end bent like a hook.

During the next period, the Upper Paleolithic (50 - 000 years ago), bladed tools appeared. They were long, sharp tools made from a special kind of flint. They laid the foundation for scrapers, drills and so on. One type of these tools was widely used: needles with an eye made of bone were used for sewing together animal skins.

What role did Russian emigrants play in the development of US aviation?

The majority of Russian aviation engineers, who found themselves in exile after 1917, settled in countries with a highly developed industry (in the USA, France, Germany) and played a significant role in the further development of aviation. Russian aviation engineers did a lot especially for US aviation. The most famous of them was Igor Ivanovich Sikorsky (1889-1972), one of the pioneers of the aircraft industry.

The first aircraft of his design (C-2) Sikorsky took to the air in Russia in 1910. In 1912-1914, he created the Grand, Russian Knight, Ilya Muromets aircraft, which marked the beginning of multi-engine aviation. In 1919, Sikorsky emigrated to the United States and settled in the city of Stratford (Connecticut), where he first earned his living by teaching at one of the evening schools. In 1923 he founded an aviation company, and in 1924 he built a twin-engine biplane S-29 in a chicken coop, the best in its class and immediately became world famous.

Sikorsky's firm became a place of work for many talented Russian engineers. Their level of training was extremely high - so much so that later the people who financed the creation of new aviation firms demanded that "at least half of the recruited engineers be Russians."

Sikorsky created 15 types of aircraft in the USA, many of which were in great demand in the world. In 1928, for example, his firm produced the twin-engine amphibious S-38, which flew, landed, and splashed down where only hunters and Indian feasts had been before. Sikorsky also created the first serial passenger transoceanic airliner S-42.

On the basis of Sikorsky's company, the well-known Pan American airline subsequently arose. Since 1938, Sikorsky began to create helicopters, one of which (S-47) became the only one used on the fronts of World War II by the countries of the anti-Hitler coalition. Sikorsky was the first to build turbine helicopters, amphibious helicopters with retractable landing gear and "flying cranes".

Sikorsky's helicopters were the first to fly across the Atlantic (in 1967) and Pacific (in 1970) oceans (with in-flight refueling). Sikorsky is deservedly considered the number 1 helicopter pilot in the world.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Music is the secret of children's progress 14.04.2018

European experts conducted an interesting experiment that showed what can affect the performance of children.

As it turned out, music lessons in art schools can positively influence short-term memory in children. A positive effect was also noticed in the study of a foreign language by a child.

Also, the authors of the work emphasized that almost all music lessons were removed from schools, but it is these lessons that have a positive effect on the mental and intellectual abilities of the child.

The study was conducted with the participation of children from Dutch schools. Specialists monitored children who attend music lessons, as well as those who do not.

After 2,5 years, it was noticed that music helps to improve the performance of schoolchildren, develop their visual and spatial memory.
