Who Invented the Parachute?

Imagine entering the airspace at a height of five kilometers and then landing calmly, as if you jumped down from a 3-meter fence. You could do it - with a parachute! A parachute is just a large umbrella that creates air resistance. With a parachute, a person can descend through the air slowly enough to avoid injury when falling to the ground.

The parachute is probably the oldest idea for a crewed flying device. Leonardo da Vinci sketched it in his notebook in 1514. Fausto Veranzio published a description of a working parachute in 1595. The first person to practically use a parachute is the Frenchman J. Blanchard. In 1785, he dropped a dog from a balloon in a basket to which a parachute was attached. Blanchard claimed that in 1793 he himself made a parachute jump from a balloon, breaking his leg on landing.

Another Frenchman, J. Garnery, is credited with starting the regular use of the parachute. His first demonstration of a parachute jump took place in Paris on October 22, 1797, when he successfully jumped from a height of over 600 meters. Garnery's parachute was shaped like an umbrella, made of white canvas and was about 7 meters in diameter. Under the dome, in the middle, there was a piece of wood in the shape of a disk with a cross section of about 25 centimeters, with a hole in the center through which air passed. The disc was attached to the tarpaulin with many short ribbons.

The first successful parachute jump from an airplane was made in 1912 by Captain Barry in St. Louis, Missouri. During 1913 and 1914 there were discussions as to whether it was advisable to use parachutes to jump from airplanes for the purpose of rescue. By the beginning of World War I in 1, this issue had not yet been resolved. The problems were partly related to the size of the parachute, as well as the fear that the pilot would not be able to parachute and avoid the aircraft.

Random interesting fact from the Great Encyclopedia:

Who was the first European to see the Victoria Falls?

Victoria Falls is the highest in Africa. The waterfall is not yet visible, but a terrifying roar is already heard, similar to continuous thunder. Day and night, there is a cloud of water spray above Victoria, so a rainbow hangs here all the time, even at night by the light of the moon. A lunar rainbow against a black velvet sky is an unusually beautiful sight.

The Zambezi River near the waterfall reaches a width of almost 2 kilometers, and this huge mass of water falls down from a rocky ledge 107 meters high. Victoria Falls - a whole cascade of waterfalls that fall down into one boiling cauldron. These are the Main Falls, Eastern, Rainbow and Devil's Falls.

The first European to see the Victoria Falls was David Livingston in 1855. He gave the name to these waterfalls. A few meters from the rapids of the Devil's waterfall, a monument was erected to him: a bronze figure in a jacket, trousers tucked into boots, and a Bible in his hands. On the pedestal is the inscription: "David Livingston - missionary, explorer, liberator." The city, 11 kilometers from the waterfall, received the name of this brave, kind and disinterested person.

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 Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

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. ... >>

Interesting life improves immunity 06.10.2016

It is known that sometimes environment and lifestyle influence the immune system more than genes. For example, scientists, comparing the state of the immune system in identical and fraternal twins, found that non-hereditary factors overlap hereditary in 3/4 of cases; that is, vaccinations in the past, germs and toxins that once had to fight, diet, and even how much a person took care of his teeth - all this determines the state of the immune system to a much greater extent than the genetic instructions inherited from parents . But after all, non-genetic factors are not limited to toxins, bacteria, diet and bad teeth.

Researchers from Queen Mary University of London found that the activity of T-lymphocytes largely depends on how diverse the environment around the individual is. T-lymphocytes are one of the best known immune cells; it is they who recognize foreign molecules, they kill infected and cancer cells, and they, by the way, regulate the strength of the immune response.

What does "diverse environment" mean? The experiments were carried out on mice that naturally lived in special cages. Usually the mice had nothing but sawdust on the floor of the "apartment" and some other material for the nest. But for some animals, not only were they given a bigger cage, they also piled all sorts of useless rubbish in the form of large wood chips, multi-colored boxes, some kind of fabric tubes; in addition, mice were given useful objects, such as a squirrel wheel, with which they could play. That is, the landscape around the animals was made extremely diverse.

After two weeks of such an interesting life, the immunity of animals changed: when T-cells isolated from them were stimulated with substances that supposedly indicated the invasion of infectious agents, then T-lymphocytes in response synthesized more interleukin-20 and interleukin-17 - signal proteins, on which they depend immune response to infection. In addition, the T cells of mice that lived in a diverse landscape increased the activity of 56 genes, again associated with anti-infective processes and with the regulation of autoimmune processes. That is, life in a diverse environment clearly benefited the immune system.
