What happens when you feel dizzy?

Every creature living on earth must have a sense of balance. Since everything is attracted to the ground by gravity, everyone must navigate in space in order to move normally.

The human organs responsible for the sense of balance are called the semicircular canals. These are three tubes located in the ear, stretched in the form of a semicircle.

Why are there three? Because space has three dimensions. Here are three channels and are located in these three directions.

The tubes contain liquid, at one end they have a spherical extension, which is called an ampoule. In these ampoules, stiff hairs grow from sensitive cells associated with nerve fibers.

When the fluid in the channels moves, it causes the hairs to bend, after which signals are sent to the brain and muscles. Because the tubes are in three different positions, moving in either direction will cause the hairs to respond to it. For example, when driving a car, the hairs in two channels are inactive, but in the one responsible for moving forward or backward, the hairs are bent. The reason for this is the liquid.

Now let's say we're spinning fast. The fluid in the horizontal semicircular canal will bend the sensitive hairs back. When we stop, the lymph will continue to move in a circle by inertia. This will cause the hairs to bend in the opposite direction. And at this moment we will feel that we are moving in a circle, although we are standing still; or that the whole world revolves around us. In other words, we feel dizzy.

How did the poet Johann Wolfgang Goethe influence the development of painting?

The German poet, thinker and naturalist Johann Wolfgang Goethe (1749-1832) at one time wanted to become an artist, but he lacked talent. He wrote a treatise "To the teacher of drawing", in which he foresaw the modern theory of colors. This book was translated into his native language by the English painter Joseph Mallord William Turner (1775-1851).

Goethe described how best to use the laws of color perception in painting. Turner recognized his point of view and used it in his work.

According to experts, it was under the influence of the ideas set forth in the book that Turner was able to convey in his canvases those subtle visual impressions that arise when light is reflected by water or viewed through rain, steam or fog. Some features in Turner's brushwork anticipated French Impressionism and Expressionism.

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. ... >>

There are lees to every wine 04.06.2005

Tests carried out at the Institute for Solar Energy Systems in Freiburg (Germany) showed that the actual efficiency of various solar battery systems does not correspond to the declared one, being much lower in mass production.

Thus, thin-layer solar cells based on copper diselenide and indium or gallium, from telluride and cadmium selenide, from amorphous silicon give an efficiency of about half the values measured by their creators in the laboratory. Polycrystalline silicon batteries instead of the promised 16,7% give 13%, monocrystalline - instead of 22%, they have an efficiency of 17,4%.

The fact is that very thin and expensive technologies are used in research institutes when developing new solar batteries. In real production, one has to compromise, reducing the cost of production.

In addition, in scientific laboratories, the characteristics of individual elements are measured, and in practice, entire modules.
