From simple knot "bloody knot" differs in that its running end, being introduced into the loop, is once again wrapped around the root of the cable. This almost doubles the size of the node.

The ancient inhabitants of Peru - the Incas - used similar knots with a different number of hoses in the knot letter they invented. By tying knots on ropes of a certain color and with the number of hoses inside each knot from one to nine, they kept count up to a five-figure number.

There are two ways to knit such knots. If the number of hoses does not exceed three, they are made by the running end of the cable inside the loop (Fig. 2, a), and if it is more, then the hoses are made around the root of the cable and the running end is passed inside (Fig. 2, b).


Rice. 2. "Bloody" knot: a - the first knitting method; b - the second way of knitting

From the distant times of the sailing fleet, such multiple simple knots were called "bloody" by sailors from different countries. In the register of punishments for sailors of the military fleets of the past, there is a beating, forgotten today, with molts and whips, which were called "cats". They were a whip woven from a hemp cable, which had from seven to thirteen braids, but more often - nine. Each of the pigtails ended in a knot, on which there were from two to nine hoses. "Cats" were divided into simple and thieves. The latter were more difficult. They were flogged for theft.

When punished with a "cat", the offending sailor was tied by the hands to a lattice hatch, which was placed vertically on the quarterdeck, or to the barrel of a cannon. As a rule, at the same time, the entire crew of the ship was lined up along both sides, and the boatswain (or his assistant), to the beat of a drum, struck blows with a “cat” on the bare back of the punished. The number of hits was in the dozens. Depending on the offense, the sailor could receive from one to twelve dozen as a punishment. Usually, after the third blow, blood appeared on the offender's back, as the knots, tightly tightened at the ends of the "cat" pigtails, cut through the skin (hence the name of the knot). After the first dozen blows, the bloody pigtails of the "cat" stuck together into one bundle and the blows became unbearable, the sailors lost consciousness and died in a state of shock. In order not to lose well-trained sailors in this way in peacetime, the British Admiralty in the middle of the XNUMXth century issued a sanctimonious order: after the first dozen blows, the boatswain's assistant was obliged to separate the pigtails of the "cat" stuck together with blood. This procedure was called "combing the cat." It was repeated after every dozen strokes. But even the most hardy sailors could not withstand six dozen blows, lost consciousness from pain and died.

In modern English, the idiomatic expression "To scratch the cat" has been preserved, which, recalling the barbaric punishment on ships, now has the meaning "to alleviate suffering."

Nowadays, the "bloody" knot has lost its purpose and finds another use both in everyday life and in various professions, for example, in tailoring and bookbinding to thicken the end of the thread.

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 ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Fossilized unicellular can help find methane in the ocean 04.04.2023

A research team led by a Brown University scientist has discovered a new way to track the transformation of deep-sea methane deposits into a gas previously invisible to researchers. In this they were helped by benthic foraminifers - unicellular organisms from the order Miliolida. Scientists have found that these organisms act as a so-called indicator when it comes to the process of dissociation of methane hydrate.

Deep sea methane deposits are deposits in the form of ice under the seafloor. The process of converting ice-like methane into gas rising to the surface is called methane hydrate dissociation. And the fossilized shells of the single-celled organisms Miliolida, in fact, act as indicators of the places where this process occurs, even when the amount of gas released is extremely small.

In the study, the scientists examined nearly 400 individual Miliolida fossils that witnessed previously unrecorded capitalized methane-to-gas events in the Bay of Bengal in the northern Indian Ocean over the past 1,5 million years. However, these processes were extremely small so that scientists could identify them using other signs. In addition, the researchers found that all of these dissociation events were largely caused by rising water temperatures in the region.

Now experts believe that global warming affects not only climate change, but also processes occurring deep at the bottom of the ocean. It is hypothesized that further warming could affect ancient methane deposits, which happens more frequently than previously thought.

According to lead author of the study, Stephen Clemens, a professor of geological sciences at Brown University, his and colleagues' study demonstrates that the transformation of methane crystals into gas is more serious than previously thought, especially when the Earth's climate is in a warm phase.

The researchers found that three species of the phylum Miliolida forminifera are able to serve as indicators of this process, namely: Pyrgo spp., Quinqueloculina spp., Spiroloculina spp.

Identifying large dissociation events is not really a difficult task for scientists; they leave their marks in the sedimentary record. However, now experts will also be able to use fossilized unicellular organisms to find smaller events.
