What color is the water?

The usual answer to this question is that water has no color, that it is "clear" or "transparent" and that the sea only appears blue because of the sky reflected in it. It's a delusion. The water is really blue. Incredibly faint shade, but still blue. You can see for yourself if you look into a deep hole in the snow or through the thick ice of a frozen waterfall. And if you take a very large and very deep white pool filled with water and look through it, the water will turn out to be blue.

However, this subtle hue does not explain why sometimes the water takes on a striking blue appearance when we look not through it, but at it. The reflected color of the sky definitely plays an important role here. On a cloudy day, for example, the sea doesn't look that particularly blue.

But still, not all the light that we see is reflected from the surface of the water; some of it comes from under this surface. The dirtier the water, the more light it reflects.

Large bodies of water, such as seas and lakes, tend to have high concentrations of microscopic plants and algae in the water. In rivers and ponds, there is a lot of soil and other solids in suspension.

All of these particles reflect and scatter the light returning to the surface, resulting in the huge variety of colors we see. This explains why the Mediterranean sometimes appears emerald green under bright blue skies.

Random interesting fact from the Great Encyclopedia:

Where is Bucephalus from?

If not everyone, then many have heard about the Akhal-Teke. These are horses of extraordinary beauty, and there is no equal to them in endurance. Well, or, in any case, it didn’t exist when the Akhal-Teke horse was not a sports horse, as it is now, but the horse of the pastoralists of the desert - the Turkmens, who lived on the border of the great Karakum desert and the foothills of the Kopetdag.

Life in the desert is not sugar. Moreover, this territory was under the rule of the Persian Shah, and the military detachments of the Persians levied tribute from the population when they could. Turkmens are not rich, but brave and independent people. And one of the sources of their existence was alaman - the so-called raid on the lands of Persia, present-day Iran.

However, all roads in the desert are roads from one well to another. And on most of the wells in the foothills there were small fortresses - bats - with Persian garrisons. A detachment of warriors heading for Persian lands had to covertly and very quickly, bypassing large wells, so as not to raise the alarm, overcome 200-300 kilometers. And after the raid - to return back, leaving the persecution, again bypassing the wells. At the same time, horses, in addition to riders, also had to carry prey. It was for such work that the famous Akhal-Teke horses were bred. The agility of the Akhal-Tekes did not strike the imagination. But they could carry a rider for several hours without a break at a speed of 30-35 kilometers per hour. And this meant that no matter how frisky the horses under the pursuers were, having a head start of 2-3 kilometers, the Turkmen on the Akhal-Teke was elusive. The detachment, if necessary, overcame 100-150 kilometers in a day, and could go at such a speed for several days in a row, which was beyond the power of any other horses. The Akhal-Teke people could go without water and food for a long time; in the raids, the Turkmens fed them with small portions of mutton fat.

They say that the famous Bucephalus, the horse of Alexander the Great, was from those places - a representative of those horses that became the ancestors of the Akhal-Teke.

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. ... >>

Australian rock art 10.05.2011

In the north of Australia, in the area where people who sailed from Indonesia are believed to have landed for the first time 50-60 thousand years ago, archaeologists have found thousands of drawings made on the rocks with red and orange mineral paints. Moreover, so far the expedition has studied only ten square kilometers of the vast rocky desert, where the drawings are found.

Apparently, over the centuries and millennia, the style and content of the drawings changed: over the elongated figures of people, often armed with boomerangs and darts, images of local animals were later applied with a brighter pigment. It is not yet possible to determine the age of this art gallery in the desert. Carbon-14 dating requires organic matter, which ancient paints do not have.

Only on one "fresco" was found a long-dried nest of wasps - it is 17 years old (this coincides with the age of the drawings of a prehistoric man in the French cave of Lascaux). So the drawing is older than the hornet's nest. But for a more accurate determination, it is necessary to analyze the paints using X-rays, and for this it is necessary to deliver an X-ray spectrometer to the desert.
