Comments on the article

It is known how often glasses burst, sometimes even without any apparent reason, but in most cases due to a sudden change in temperature, when, for example, hot water is poured into a cold glass, or vice versa. In view of this, we consider it useful to give the following simple and repeatedly tested method glass tempering, with which glasses can be given the ability to perfectly withstand sudden changes in temperature.

To this end, the glasses, individually wrapped in straw, are placed in a metal (fish) cauldron, into which water at room temperature is poured and placed on the stove so that the water gradually boils. Then, having kept the glasses in boiling water for 5-6 hours, the cauldron is removed from the fire and covered with some kind of blanket so that the water cools down gradually.

When the water temperature equals room temperature, the glasses can be considered already fully tempered and withstand very well, without bursting, abrupt transitions from hot to cold water or 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. ... >>

M-Disc - optical long-liver 28.10.2011

Hitachi and LG are investing in a new media format called M-Disc. This is an optical disc that is fully compatible with existing DVD drives, but more resistant to wear and tear.

During the experiments, M-Disc was subjected to high temperatures (85°C), humidity and light irradiation. M-Disc turned out to be the only "survivor", which confirms its ability to store information reliably and for a very long time - engineers call a figure of 10000 years.
