How is it established that animals do not distinguish colors?

Scientists have conducted special experiments to determine whether animals can distinguish colors. All they can say with certainty from these experiments is that some of the animals are color blind.

Take, for example, a dog. They made a sound and gave her food. When she got used to it, it was enough just to repeat this sound, as the dog salivated. When the same experiment was repeated, using this or that color instead of sound, nothing came of it. This led to the conclusion that dogs do not distinguish colors.

Similar experiments were carried out with cats. They were tried to be fed at the signal of one of the six colors. But if instead of a color signal they were shown just something gray, they did not notice the difference and constantly confused the signals. This means that cats also do not distinguish colors.

It is known that monkeys distinguish colors, and experiments have proven this. They were taught to take food from a locker whose door was painted a certain color, and they never approached doors that were painted in other colors and there was nothing behind them. But scientists admit that this issue is still not well understood. And, perhaps, further experiments will expand our understanding of animals. For example, it turned out that horses distinguish between green and yellow, and also distinguish them from gray. Things are much worse with red and blue.

Which plane is the fastest?

Currently, the American Lockheed SR-71A reconnaissance aircraft remains the fastest aircraft, although it is far from new. On July 28, 1976, it managed to develop a record speed - 3529 kilometers per hour. At such high speeds, the aircraft heats up to 400 °C. Pilots cannot fly it without a special space suit.

The same aircraft was used for the fastest flight across the Atlantic. The Lockheed SR-5570A covered a distance of 71 kilometers from New York to London in just 1 hour and 54 minutes. The unofficial English name for this aircraft means "Blackbird". The fastest aircraft in the world received this nickname for its dark color.

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 ... >>

Mirrors in orbit will ensure round-the-clock operation of earthly power plants 26.01.2024

Scientific research carried out at the University of Glasgow provides a new perspective on the use of solar energy. The idea is to place an array of mirrors in Earth orbit to collect sunlight and direct it to solar panels on Earth, providing a constant flow of energy even at night.

Calculations by Scottish scientists show that one mirror installed on an orbiting satellite is capable of illuminating an area of solar panels of 17 square kilometers for 10 minutes, which gives an increase of 34-36 megawatts of energy.

It is proposed to place satellites with mirrors in a sun-synchronous orbit at an altitude of 900 kilometers. The hexagonal mirrors, with a total area of 162,380 square meters, will collect sunlight and direct it to the Earth, adjusting their position depending on the location of the sun. This advanced approach will allow satellites to illuminate arrays of solar panels, powering large power plants even at night.

Five of these satellites with mirrors will be able to power 13 large solar power plants in different countries during the night and at dawn, reaching a total capacity of up to 284 megawatts.

The reflected light from space will be almost undetectable on Earth, except in the areas of solar panels, and will have no effect on space observations.

The concept of using mirrors in orbit to continuously harvest solar energy represents a new step in the development of renewable energy sources. This technology opens up new prospects for the efficient use of solar energy at any time of the day, providing a sustainable and constant energy supply for the earth's power plants.
