If it seems to you that space technologies are something very distant and unnecessary in earthly life, then you are very mistaken. For example, a smartphone would never be the same as it is now if it weren't for space engineers.
Remember how on push-button phones you had to poke at the keyboard for a long time to find the right letter, and then also make a smiley face out of characters, for example, like this:’-). With the advent of touch phones, life, of course, has become easier, and with the advent of messengers — faster. In 10 seconds we manage to discuss the whole day, and earlier during this time the SMS only managed to reach the addressee. It seems that everyone has gone online now, and what remains for mobile operators?
It's hard to meet a person who wouldn't use a smartphone. However, there are not a few who suffer from persistent fear of a phone call. Telephone phobia, or telephobia, was first described by British researchers in 1990. It is now recognized as a type of social anxiety disorder.
Laser radiation usually heats up the material it is directed at. However, there is a way to reverse the phenomenon and cool the substance with a laser beam. The reverse effect will allow you to create sensitive sensors for accelerometers that use lasers.
For every successful technological breakthrough, as a rule, there are dozens of failures. Success depends on many factors, including the promotion strategy, competition and other details of the business plan that are not directly related to the idea itself. A device or service can be talented, but simply ahead of time. We decided to remember the brightest technological breakthroughs that were supposed to take off, but something went wrong.
Never before has a person's life changed so dramatically as it has changed in the XXI century. The main marker of the new era, of course, is the abundance of all kinds of devices with which we interact sometimes even more than with other people. It is not surprising that the new way of life creates new dilemmas: in particular, the question arises how dangerous smartphones, computers and other gadgets are for our vision.
Experts from the Gallup research agency (USA) say: about every second adult in developed countries is more or less painfully dependent on a smartphone. They are echoed by colleagues from Italy: according to the National Service for Children and Youth of this country, half of Italians aged 15 to 20 check their phones at least 75 times a day, and 62% write messages at night. One can argue about whether phone addiction is as severe as addiction to cigarettes or alcohol, but many of us really find it difficult to imagine our life without a smartphone. Where is the line between the need to always be in touch and a painful addiction? We cannot answer this question, but we can offer a small checklist: if most of the symptoms are familiar to you, it may be worth taking action.
