Do animals see colors?

Everywhere we look, the world seems so colorful and beautiful to us, and it's hard to imagine that someone sees it in a completely different way. But how can a person determine whether animals see colors if they cannot tell about it?

Scientists have conducted many experiments to answer this question. Bees have been the subject of hundreds of such tests because it would be interesting to know how a bee finds a flower, if not by color. The following experiment was carried out: a little syrup was poured on a blue card, and a red one was left empty. Released bees flew blue. Then everyone did the opposite: they poured syrup on the red one, but not on the blue one. But the bees still flew to the blue one. So it was proved that they distinguish colors.

Two strange features of the perception of flowers by bees were soon discovered. First, they do not distinguish red. They see it as dark gray or black. Secondly, they perceive ultraviolet rays as color, although for a person it is only darkness!

Male birds are often brightly colored. Does the female perceive these colors? In experiments conducted with chickens, it has been proven that they see all the colors of the rainbow! But here's what's amazing: a man's friend - a dog - does not distinguish colors. For a long time it was believed that the dog is as perfect in perceiving colors as in distinguishing smells, sounds, sizes, and so on. But true dog lovers were not very disappointed after this discovery, as the flair completely compensates for this shortcoming. By the way, cats also do not distinguish colors.

Monkeys have a very good sense of color, but most other mammals, including the bull, do not see colors!

The reason for this phenomenon is that most of these animals hunt at night, when they do not need to distinguish colors at all, moreover: they themselves most often have a dull color, so this ability is of little importance in their life.

 Random interesting fact from the Great Encyclopedia:

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 of 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.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Power lines for green energy 02.02.2016

American scientists led by Alex MacDonald have developed a scheme for transmitting solar and wind energy through power lines domestically, which circumvents the problem of storing such energy and reduces carbon dioxide emissions by 80%.

Until now, the widespread use of green energy has been limited by the inconsistent nature of its production: the sun does not always shine, and the wind also blows. Therefore, the generated energy must be stored somewhere in order to be used later during periods of darkness or calm. Storing sufficiently large energy reserves requires complex and expensive equipment. An alternative option was to transfer energy from those areas where it is generated to those where this is not currently happening - however, until now it was believed that the design features and capabilities of existing electrical networks do not allow this.

And now McDonald and his colleagues have proven that with the help of new high-voltage direct current (HVDC, i.e. High-Voltage, Direct-Current) power lines, it is still possible to transfer green energy from one region of the country to another. Since the wind is always blowing in some part of the US, this will effectively provide (partly) the country with energy. In this case, it will no longer be necessary to store it.

The transfer of green energy from one area to another, according to NOAA experts, will be handled by a special computer program that will determine how to do it in the best way. Scientists have already created a working model of such a system and proved its effectiveness. In McDonald's model, the entire country was divided into 152 square meters, according to the number of district electricity networks.

Calculations have shown that with the introduction of this system, the United States will be able to reduce carbon dioxide emissions by 2030% by 80 compared to 1990, without spending resources on solving the problem of storing "green" energy.
