This experience should be shown only to those of your friends or acquaintances who do not take offense at you under any circumstances. Why? But think for yourself...

Take a tin can, preferably from under concentrated condensed milk, which can be poured out by punching two holes in one of the bottoms with a clove. In the same bottom, you need to make several more of the same holes. But on the opposite side, punch a barely noticeable, small hole with a carnation.

Now you need to lower the jar into a pot of water, and on the side with several holes. After waiting a while, cover the top hole with your finger and pull the jar out of the water so that the sieve is at the bottom.

Let now one of the guys look at the bottom of the jar, under the bottom. Hold the top hole firmly with your finger. Look under the bottom yourself. Nothing special, a bank like a bank, only with holes. But one of your best friends looked under the bottom of the jar, best of all, one who loves all kinds of pranks ... Hurry, release your finger that closes the top hole!

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. ... >>

Chinese children will be limited in the use of gadgets 28.07.2023

The government of the People's Republic of China continues to impose strict restrictions on the use of digital devices among teenagers. Whereas in 2021 the country limited gaming time for under-18s to just 3 hours a week, a new initiative is now being discussed regarding even tighter restrictions on smartphone use, based on information received from Mezha Media.

China's Cyberspace Authority has put forward a draft regulation that recommends that teenagers under 18 limit smartphone use to just two hours a day. For the age group from 8 to 15 years, the limit is one hour per day, while for children under eight, a limit of 40 minutes is assumed.

In addition, the new rules also propose a ban on the use of smartphones between 22:00 and 6:00. Every mobile phone must be equipped with a parental control mode that will allow parents to control their children's access to certain content, as well as give ISPs the ability to provide age-appropriate content. The youngest, children under three, will be subject to the restriction on audio content such as songs and other audio formats, while children aged 12 and over will be able to access educational and news content.

Although the project is under discussion and its final approval is still unknown, it should be remembered that this concerns the PRC, and the likelihood of these measures being implemented is quite high. Questions arise regarding the mechanisms for implementing these restrictions. It is not yet clear whether the responsibility for providing child mode will lie with hardware manufacturers or operating system developers.

If these restrictions are implemented, then Chinese software developers such as ByteDance (creators of TikTok and its Chinese version of Douyin) and Tencent (WeChat and many other popular games) will have to adapt their applications and content to the new standards.
