What is a whirlpool?

When we think of whirlpools, we imagine a huge swirling mass of water that pulls people and ships in, bringing destruction and death. Although whirlpools are dangerous, they are not able to suck in or absorb anything.

Let's see what a whirlpool is. You have probably observed small whirlpools in the stream. They form where the shore protrudes into the stream and imparts rotational motion to the stream.

Rotating in a small space, the water tends to the outer edge of the whirlpool, creating a recess in the center. This is the result of centrifugal force. It is this force that keeps the water in the bucket when we spin the bucket.

What is the nature of the large whirlpools that supposedly pose a danger to ships and people? When one wave overtakes the previous one, ocean currents get a rotational motion. This is especially common in narrow straits between islands and land areas.

If such a narrow strait is of sufficient depth, when the tide passes through it, we observe the formation of funnels in a rotating mass of water. But, as we said, this does not happen in the open oceans. A whirlpool in the ocean is just a turbulent movement of water on a large scale, that is, the rotation of water.

Whirlpools are observed in various parts of the world. The most famous are three of them - the Maelstrom, Charybdis and the whirlpool downstream from Niagara Falls. Maelstrom is located off the coast of Norway, Charybdis - in the strait between Italy and Sicily.

Random interesting fact from the Great Encyclopedia:

What did the Siamese kings give to the objectionable nobility?

An approximate analogue of the expression "suitcase without a handle" in English is the idiom "white elephant" ("white elephant"). It comes from a tradition when the Siamese king gave this animal to a noble person who was not to his liking. By virtue of their sacred status, white elephants were not supposed to work, but the burden of maintenance sooner or later ruined the owner.

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 ... >>

Danger-signaling plant genes found 23.03.2020

Scientists from the Salk Institute for Biological Research (Salk Institute) have found the exact location of the genes, whose purpose is to signal danger.

The plant hormone, jasmonic acid or jasmonate, is responsible for the plant's response to external irritation: insect attack, fungal infection, drought, heat or cold. By examining plant cells after exposure to jasmonic acid, scientists have determined which genes are responsible for the plant's response to danger.

The guinea pig Talya became the test subject: the genome of this representative of the mustard family is well studied. The results of studies of the rucifera can be extrapolated, since jasmonic acid is found among representatives of the entire plant kingdom. The seeds germinated in the dark were treated with jasmonate, after which the researchers extracted DNA and proteins from the cells. To determine the exact location of the genes that regulate the plant's behavior in times of danger, the scientists used specific antibodies against the proteins of interest.

"The aim of our study was to see how plants process information from the environment, how this information affects their growth and development," - shared Professor Joseph Ecker, co-author of the report, a researcher at the Howard Hughes Medical Institute, - As a result, we have identified genes responsible for for the response to jasmonic acid, and found sites involved in cellular cross-communication with other plants. This will allow breeders to develop crops that are more resistant to harsh conditions."
