Why are the knights of the Teutonic and Livonian orders called dogs?

In one of the works, Karl Marx called the Teutons "Reitershunde", that is, horse rabble. The word was inaccurately translated as "dog-knights", and this term, especially after its appearance in the film "Alexander Nevsky", was fixed in Russian for the soldiers of the Teutonic and Livonian orders, although there were no dog attributes in their appearance and ammunition.

 Random interesting fact from the Great Encyclopedia:

What is the Dead Sea?

What is the peculiarity of this sea? In reality, it is rather a huge salt lake located between Jordan and Israel. It is formed in a depression or crack in the earth's crust that exists in this region. The Dead Sea stretches for about 75 km in length, reaching a width in various places from 5 to 18 km.

Surprising is the fact that the surface of the Dead Sea is 400 m below sea level. In its southern part, its depth is small, but in the northern part it reaches 400 m. Unlike ordinary lakes, not a single river flows out of the Dead Sea, but it itself absorbs the waters of the Jordan River, which flows into it from the north, and many small streams flowing from the slopes of the surrounding hills.

The only way excess water is removed from the sea is by evaporation. As a result, an unusually high concentration of mineral salts was created in its waters, such as table salt, potassium carbonate (potash), magnesium chloride and bromide, and others. Therefore, the Dead Sea is the saltiest sea in the world. The concentration of salts in its water is 6 times higher than in the ocean! This increases the density of the water so much that a person floats here like a cork without any effort!

The Dead Sea can serve as a huge source of valuable substances. According to scientists, about 2 tons of potash are dissolved in it, which is used to produce fertilizers for the soil.

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 ... >>

Hand washing is more effective than disinfection 04.04.2024

Hand hygiene is a key element in preventing the spread of infections and maintaining public health. However, contrary to popular belief, disinfectants are not always the best choice. Scientists from Penn State Health in the US confirm that traditional hand washing with soap is more effective than using disinfectants.

Sanitizers may seem convenient, but research shows they are not as effective as washing your hands with soap and water. Scientists note that soap acts as an excellent cleanser, removing not only dirt, but also germs from the skin. Regular hand washing with soap and water for 20 seconds will achieve optimal results.

Additionally, disinfectants are not always effective against all types of pathogens. Some pathogens, such as norovirus and Cryptosporidium, may remain resistant to disinfection. In addition, disinfectants may not be effective against certain chemicals such as pesticides and heavy metals.

Experts emphasize that proper hand washing with soap can not only effectively cleanse the skin of germs, but also provide protection from chemicals that a person may come into contact with in everyday life.

Traditional handwashing with soap and water remains the best method for maintaining hand hygiene. This simple act has a significant impact on preventing the spread of infections and maintaining public health.
