Which currencies are named after measures of weight?

The names of many monetary units are closely related to various measures of weight. A typical example is the British pound sterling: silver coins were called sterling, and 240 of these coins weighed one pound. Similar is the origin of the currency of a number of countries called the lira, which is the Italian equivalent of the weight unit pound.

In medieval Western Europe, a mark was used to measure the weight of silver, which was slightly lighter than a pound - the Deutschmark came from it. Finally, the monetary unit hryvnia in Ancient Rus' was pronounced as “hryvnia silver” or “hryvnia kun” and denoted a certain number of coins, having the same meaning as a pound or a mark.

Who made the first doll?

Today we have dolls that walk, talk, scream, sleep, drink - they are as close as possible to living beings. But imagine a poor girl whose parents cannot buy a doll. She will take a piece of log, dress it up in clothes and say that this is her doll. And it will be a doll! It is only necessary that the child considers her a doll. For this reason, we cannot determine when the dolls originated. Probably from prehistoric times, because when there were children, there were also dolls.

Indian children used for this a piece of wood with a thickening instead of a head. Persian children played with dolls folded from fabric with a face painted on it. Dolls made of clay or bone have been found in prehistoric child graves around the world. Some authorities say that for the first time the doll was used in religious cults. Children were allowed to hold the doll as an idol, an image, but it was forbidden to play with it.

Others claim that children played with dolls in prehistoric times. Among the earliest dolls that have come down to us were those of the ancient Egyptians. In general, it seems that they were very partial to dolls. They made them out of wood and decorated them with beads. The found Egyptian dolls are over 3000 years old.

The ancient Greeks also had interesting dolls. They had well-shaped heads, and their arms and legs moved with ropes. And in our time, in various parts of the world, children play with dolls that are completely different from ours, and which they will prefer to ours. A little Eskimo plays with an ivory doll. A girl from Mexico - made of baked clay, and it seems to her that our dolls are too pale.

Modern dolls are made from wax, fabrics, papier-mâché, and other materials. The heads of the most expensive dolls are created by the best artists. But you perfectly understand that a girl’s favorite doll may not be the most expensive one.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Unpleasant rattle 15.02.2017

Austrian researchers Michael Euler and Christoph Reuter found that the most disgusting sound waves lie between 2000 and 4000 Hz, the range in which our ear maximizes sound and to which we are most sensitive.

Scientists conducted an experiment involving 24 subjects, none of whom were musicians. Each person listened to a recording of eight sounds in random order and rated them from 1 to 6 points. The sounds were a modified scratching of nails on a chalkboard.

The scientists also recorded physiological responses to stimuli by measuring subjects' skin conductance, heart rate, and breathing while listening to the recordings. Finally, they analyzed psychological factors, differences between subjects who knew about the nature of the origin of the sound (Group "A") and those who thought they were part of a piece of music (Group "B").

As a result, Euler and Reuter found no significant difference in physiological responses between the two groups. The difference was in the scores, which were lower if the subject knew that he heard the sound of nails on the board. However, removing frequencies between 2000 and 4000 Hz makes this sound a bit more "tolerable".
