Who was the first astronaut to go into outer space?

Why did man need to go into space? It is impossible not to go into space, just as, swimming, say, in the ocean, one must not be afraid to fall overboard and not learn to swim. An astronaut who goes into space must be able to perform all the necessary repair and production work, for example, to weld! .. A situation may arise when one ship must provide assistance to another.

On March 18, 1965, the flight of the Voskhod-2 spacecraft began, the commander of which was pilot-cosmonaut Pavel Ivanovich Belyaev, and the co-pilot was pilot-cosmonaut Alexei Arkhipovich Leonov. A television program was broadcast from the ship about the first spacewalk of a man, a film called "In a spacesuit over the planet" was shot.

Aleksey Arkhipovich Leonov, dressed in a soft protective suit, got out of the ship through the hatch of the airlock. Overboard, he spent 10 minutes, which showed that it is possible to work in space. At an altitude of almost five hundred kilometers above the Earth, at a speed of 28 kilometers per hour, a man flew in open space, who became a satellite of the Earth for 000 minutes.

What taste and nutritional properties do white eggs differ from brown ones?

White and brown eggs do not differ in taste and nutritional properties, as well as in the strength of the shell. The color of the shell depends on the breed and color of the hen itself: white individuals usually lay white eggs, colored individuals usually brown eggs. Different prices for eggs of different colors in the store are most likely due to other parameters - for example, size. Also, the price may depend on the traditions of a particular country. If housewives in a given region prefer to buy white eggs, brown eggs may cost more because their supply is limited, and vice versa.

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. ... >>

Singing people feel the same as birds 01.01.2013

A bird listening to the singing of another bird experiences the same emotions as a person listening to music, scientists concluded as a result of a study published in Neuroscience.

"We found that humans listening to pleasant music and female birds listening to a male's song during the nesting season activated the same neural systems," says Sara Erk of Emory University. In males, hearing the song of another male, the reaction was different - the amygdala was activated, as happens in people who hear dissonant, unpleasant sounds.

Erk analyzed the results of studies that visualized the results of the nervous activity of a person listening to music. In addition, she reviewed bird brain maps from Money's lab, which uses songbirds as a model for studying neural structures in complex behavior. Some of the birds in the study were treated with hormones to encourage reproduction, while others were hormonally lowered. Outside of the breeding season, birds of both sexes used song to establish and maintain position in the flock. During the breeding season, the function of singing was different - males sang to attract females, as well as scare away other males.

The increase in male testosterone in response to someone else's singing indicated amygdala activity that correlates with the average person's response to bad music. The females, if their hormonal levels were high, clearly enjoyed the music. Those who did not enter the breeding season did not react in any way. Both of these phenomena are connected not only directly with a positive reaction to the "reward", but also with the mechanisms that regulate emotions. Both birdsong and music, according to Earl, activate ancient evolutionary mechanisms that are necessary for the reproduction and survival of the species.
