Comments on the article
The bottom figure shows a TRG circuit with a variable resistor without taps, using a filter method for correcting the frequency response. The R2R3R4C1C2 filter, which suppresses the middle frequencies of the signal, starts working at low volume levels, due to which the low and high frequencies of the audio range are raised. Variants of such a regulator are widely used in amateur developments.

Alcohol content of warm beer
07.05.2024
Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>
Major risk factor for gambling addiction
07.05.2024
Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>
Traffic noise delays the growth of chicks
06.05.2024
The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>
| Random news from the Archive New type of magnetism discovered
13.02.2024
A team of researchers from ETH Zurich in Switzerland has made a discovery that revolutionizes the understanding of the properties of magnetism in synthetic materials.
The experiment was carried out on atomically thin meshes of two different synthetic materials, stacked and forming a moiré pattern. Widely studied to understand quantum phenomena, these materials have attracted the attention of the scientific world.
Traditionally, magnetism has been explained by the spin rotation of electrons as a collective process. But the new discovery reveals so-called "kinetic" magnetism, which arises from electrons competing for space in a material.
The experiment involved atomically thin layers of molybdenum diselenide and tungsten disulfide. When voltage was applied to the structure and irradiated with an electron beam, the material became magnetic. However, it is interesting that magnetism appeared only with a significant excess of electrons.
This amazing phenomenon, called Nagaoka "kinetic" magnetism, was predicted by Japanese physicist Yosuke Nagaoka. He suggested that the magnetic field could be formed due to the competition of electrons for free space, which distinguishes it from traditional models of ferromagnetism.
This discovery not only opens new horizons in the study of quantum physics, but also highlights unexpected aspects of the interaction of electrons in thin synthetic materials. In the future, such discoveries may form the basis for the development of innovative technologies in the field of electronics and magnetic materials.
The discovery of a new type of magnetism is a significant step in understanding the fundamental processes occurring in synthetic materials. This opens up prospects for the creation of new technologies and devices in electronics and magnetism.
