What is the plus sign used by students in Israeli schools?

Religious Jews try to avoid Christian symbols and generally signs that look like a cross. For example, students in some Israeli schools instead of the plus sign write a sign that repeats the inverted letter "t".

Who invented the first dial telephone?

A patent for the first telephone set with dialing and an automatic switchboard for it was issued in 1891 to the American Elmon Strowger, a resident of Kansas City.

The inventor had nothing to do with telephony - he was an undertaker. There were two funeral homes in the city. Upon learning that the wife of a competitor got a job as a young lady at a telephone exchange, Strowger became worried: when subscribers ask to be connected to an undertaker, she certainly sends callers to his competitor! And he came up with a system that allows each subscriber to independently connect to the desired number directly from home, without intermediaries.

Strowger's first telephone was a push-button. But in 1904, the inventor introduced a rotary dialer into the device with the arrangement of numbers that is familiar to us now: zero at the bottom, one at the top, the numbers go counterclockwise.

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. ... >>

Paralyzed woman spoke through digital avatar 26.08.2023

A woman paralyzed after a brain stem stroke has become the first in the world to 'speak' through a digital avatar.

The new technology uses electrodes on the surface of the brain to translate brain signals into language and facial expressions. This discovery holds promise for brain-computer interfaces (BCIs) that could change the lives of people who have lost the ability to speak due to injury or disease.

Until that time, patients had to use slow speech synthesizers based on eye tracking or small facial movements. This technology made natural communication more difficult. The new technology uses tiny electrodes implanted on the surface of the brain to detect electrical activity in the area responsible for speech and facial movements. These cues are translated into the language and facial expressions of the digital avatar, including smiling, frowning, and surprise.

A woman named Ann, who suffered a brain stem stroke 18 years ago, is unable to speak or write and uses motion-tracking technology to select letters slowly. She hopes that avatar technology will allow her to work as a consultant in the future. The results of the study showed that the new technology is not yet perfect, as it can incorrectly decode words in 28% of cases.

However, scientists believe that this is a significant breakthrough in the development of such interfaces that can help people with loss of movement or speech. One of the next steps is to develop a wireless version of this technology that can be implanted under the skull. Experts hope this will allow people to self-manage gadgets that have great potential to improve independence and social interaction.
