Comment Re:Radiation inverse-square law (Score 1) 344

Cellphones are not isotropic radiators.

Here is the general idea of a cell phone radiation pattern: http://www.raymaps.com/wp-cont...

Obviously, it does not have a directional antenna, simply because a smartphone does not know to what tower it is connecting so it radiates in all direction.

Yes, theoretically id does not radiate from one point, but practically speaking it does.

I did not want to say that smartphone or a router electromagnetic radiation is that harmful. I do not know it.

I just wanted to inform that if one worries that it may be harmful, then it is possible to reduce the intensity of the electromagnetic radiation thousands of times by moving a device just several centimeters from the body. Because the radiation decreases by the square of distance.

Certainly, there are numerous ways people try to circumvent the inverse-square law with more or less success, including directional antennas: https://en.wikipedia.org/wiki/...

Still, this is the fundamental unbreakable law of nature. That is, by the way, why there is no powerful central cell tower in a city, but several cell towers covering the area.

It is just an example. If a smartphone is in the pocket, the distance to the body is 1 mm. If it is in the backpack, it is 10 cm, or 100 mm.

But the radiation intensity is lower not 100 times, but 100*100 = 10000, ten thousand times lower.

The inverse-square law is applicable also to such things as, say, shrapnel, light, loud sound, etc.

The intensity of radiation passing through any unit area is inversely proportional to the square of the distance from the point source. It is the fundamental law of the universe, and It is valid for any radiation, including electromagnetic: https://en.wikipedia.org/wiki/...

Practically it means, that even a small increase in distance decreases the radiation dramatically. So putting a smartphone into a backpack, or on a windowsill, away from the bed, decreases the radiation probably by several orders of magnitude.

In even simpler words, - do not keep radiating devices, like a smartphone, router, etc., too close to a place were you sit or sleep.

Comment Ageism again (Score 4, Insightful) 343

"Old IT Workers". It is one more stereotype. There are weak "Young IT Workers" too.

For example, one may think that workers in advance age miss work due to illness more often than young workers. It is a stereotype too. The research shows the opposite.

It is due to such managers we have got cute baby-face puppets at about any office and counter who do not have a clue, who do not have any real life experience. And as a result the production goes away from Europe and the US.

I would start with the retraining course "Prejudice or discrimination on the grounds of a person's age" for this IT manager.

I would like to correct the wording of my previous post above. It should be definitely - a part of people. Probably, a small part.

Because, the only general thing which could be said about American people is that they are all different. Undoubtedly there honest individuals among them.

Comment The lesson of Olympic Games in Rio (Score 1) 233

Some US athletes were claiming that they were robbed at gun point in Rio during the Olympic Games. It was a big story in the media.

Until it was proven irrevocably by the organizing side that they were just lying brazenly.

I guess that at least some part of the American people believe that they are kind of exclusive, much cleverer than others. And that they can get away with about any lie. My point is that one has to look for irrevocable evidences as soon as one hears such unusual claims.
