Who invented the airplane?

Sometimes a discovery begins with an "idea". A person has an idea that people need some kind of mechanism or product, and he begins to "invent" it.

But as for the airplane, or, as they used to say, the airplane, this idea was one of the oldest and most secret for a person. The idea of flying has captivated man since antiquity. One of the most famous legends tells about Icarus, who attached wings to his body with wax and took off! However, as he approached the Sun, the wax melted and Icarus fell and died. But the dream remained. Icarus is a symbol of human striving for new heights.

Leonardo da Vinci, who was not only a great artist, but also an inventor, left behind sketches of an aircraft that used the muscular strength of a person. There were other dreamers who dreamed of the idea of an airplane hundreds of years ago!

The earliest aircraft did not have their own power. They were, in fact, giant kites or gliders. During the XNUMXth century, many experiments were carried out with them.

But no one has succeeded in making a heavier-than-air aircraft with its own power. In fact, it was problematic - is it possible to build such an apparatus at all. The first to prove that this could be done was Professor Samuel Langley of the Smithsonian Institution in Washington. He built two flying machines, each 3,5 meters wide and 4,5 meters long, powered by a 1,5 horsepower steam engine. In 1896, these two models made successful flights. However, a test flight of Langley's life-sized aircraft ended in failure: it crashed on October 7, 1903.

On December 17 of the same year, the brothers Orville and Wilbur Wright managed to make a successful flight in an aircraft heavier than air with its own power. In Kitty Hawk, North Carolina, they made one flight of 30 meters in 12 seconds and the second of 260 meters in 59 seconds. Thus was born the airplane, or plane!

Random interesting fact from the Great Encyclopedia:

Why aren't tides the same everywhere?

Have you ever been on a beach where, in low tide, you have to walk quite a distance out to sea to even get into knee-deep water? And yet there are places where you can hardly tell high tide from low tide. The reason for this has nothing to do with the influence of the moon. Tides are due to gravity. In the same way that the Earth pulls on the Moon, the Moon also pulls on the Earth, but with much less force. Due to the influence of the Moon on the Earth, the waters of the ocean are attracted towards the Moon and form a bulge or wave. This results in a high tide.

Water on the opposite side of the Earth is much less attracted to the Moon because the Moon is farther away, and so a bulge forms here as well. Therefore, a high tide is observed both from the side facing the Moon and from the opposite side of the Earth. As the Moon passes around the Earth, these two water "humps" and lower water levels continue to remain approximately in the same position relative to the Moon. And if the surface of the Earth were completely covered with water, then the alternation of high and low tides would be very regular.

But many other factors interfere with this. One of them is huge arrays of continents. They cause tidal currents that curve around coastlines and accumulate in certain places, such as bays. On gently sloping coastlines with a straight coastline, the rising tide has enough room to spread and does not rise very high.

But where the tide meets a narrow bay or channel, it cannot spread wide, and therefore the water can reach a great height. For example, in the Bay of Fundy, the difference between high and low tide can be more than 21 meters. At the same time, at high tide in the Mediterranean Sea, the water does not rise higher than 0,5 m.

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. ... >>

The inhabitants of Pompeii sorted garbage for reuse 29.04.2020

Archaeologists have found that the inhabitants of Pompeii were engaged in sorting garbage, and also exchanged construction waste for reuse.

An analysis of soil samples that covered the debris found within Pompeii and outside the city showed that organic and construction waste was stored separately. That is, the ancient Romans sorted garbage.

"The walls of buildings in the city of Pompeii were also made of garbage - ancient Roman builders used materials such as crushed tiles, fragments of ceramics, fragments of plaster, and so on. Smooth and plastered walls are actually made of garbage. But something else is interesting .

An analysis of the soil, particles of which were preserved in this garbage, showed that it was carefully sorted before being reused. Obviously, the inhabitants of Pompeii and the surrounding area collected, sorted and sold garbage for reuse," says Allison Emmerson, professor at Tulane University of Louisiana (USA), author of the study.

It was previously believed that Pompeii's dumps were formed from garbage that was cleaned out of the city after a devastating earthquake in 62 AD, which killed 2 of the city's 12 inhabitants.) But now it has become clear to scientists that the origin of the dumps is different.
