Currently, no one has proven that exposure from cellular communications can provoke some serious illness, but the suspense is even more worrying. Many also notice increased fatigue when using smartphones, phones, tablets, modems and routers. Let’s try to figure this out?
The point of view of science Cellular communication is based on the use of microwave radiation of high-frequency waves (microwave). Favorite microwave ovens work on this principle. High-frequency waves can perfectly heat products. The same thing happens with body tissues that fall under their influence. This can have a certain effect on the human body, including nerve cells, brain neurons, and the lens of the eye. This issue is rather controversial, because there is very little information about such studies. “Too little time has passed to draw conclusions” – a replicated stamp. Continue reading
It seems that most recently with the word “telephone” we only imagined the apparatus on the table hanging on the wall or in a special booth on the street. But times have changed a lot, and now almost everyone is happy with the presence of an electronic device, which is most often called just a mobile phone. There is no such device unless in the dense taiga, where the nearest cell tower is hundreds of kilometers away.

About fifteen years ago, in the youth environment (and not only there!) There was a fashion to “measure” the size of mobile phones. Steeper was the one that in the minimum volume had the same thing as having larger devices. At the same time, the issue of the number of SIM cards in the compared devices was somehow not discussed at all. But the fact was that sold single-cell phones. In any case, only such models came from the West to the republics of the former USSR long before the comparisons mentioned above. With not very high demand for them (the pleasure was too expensive), they accumulated in lots at warehouses, and then were “imposed” on customers through aggressive advertising. Continue reading
It is believed that about 80% of information a person receives through his vision. However, this figure is highly dependent on how well we see. There are very few people with excellent vision. Many begin to lose it at school.

As a person grows up, vision gradually “sits down.” I have to buy glasses. But they do not always fully restore normal vision.
There are more and more visually impaired people in the world. Vision problems make life difficult for them. Let us dwell in detail on how scientists and specialists help these people to feel useful in society. It will be about various electronic devices that have appeared in recent years. It is extremely difficult for visually impaired people to use mobile phones. They are now of two types – push-button and touch. In this and in another case, a visually impaired person cannot do without a magnifying glass. Small numbers and letters on the keys are almost invisible even to a person with normal vision, since the keys themselves are scanty. Continue reading
