What is the Dead Sea?

The Dead Sea is a truly strange and, moreover, far from the only name given by man to this one of the most unusual reservoirs on Earth. For the first time this sea began to be called "dead" by the ancient Greeks. The inhabitants of ancient Judea called him "salty". Arabic authors referred to it as "the stinking 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 the level of the oceans. 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.

 Random interesting fact from the Great Encyclopedia:

What did the philosopher Auguste Comte consider the most striking example of such knowledge, which will forever remain hidden from man, and why was he wrong?

In 1844, the philosopher Auguste Comte (1798-1857) was looking for an example of such knowledge that would forever remain hidden from mankind. He focused on the chemical composition of distant stars and planets. Comte believed that a person would never visit them and, having no samples of a substance in his hands, was forever deprived of the opportunity to know its composition.

Auguste Comte chose an extremely unfortunate example. Just three years after his death, it became clear that the spectrum of their radiation could be used to determine the chemical composition of distant objects.

Astronomical spectroscopy made it possible to determine the composition of the gas shells of the planets of the solar system, the chemical composition of the Sun, distant stars and galaxies.

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 ... >>

Patches in pipelines 13.01.2012

Employees of the Faculty of Engineering at the University of Arizona suggest using the achievements of cardiac surgeons in construction. This is a kind of "stent" with which it would be possible to repair leaking pipelines.

The Institute of Gas Technologies has recently carried out a whole series of experiments on pipelines through which natural gas is pumped. To repair them, a PipeMedic kit was used - patches made of interlaced carbon fibers interlayered with fiberglass and filled with epoxy resin, which were introduced into the defect zone using an inflatable "catheter" (trolley inside the pipeline).

The inflatable balloon firmly pressed the patches against the inner walls of the pipe and maintained pressure for as long as it took for the epoxy to cure. After that, the freshly repaired pipe is ready for operation again.
