Its name reef knot derived from the word “reef-shtert” - a small end of a cable tied into the canvas of the sail, which was used to “take reefs”, that is, they tied a part of the sail selected to the lower luff of the sail or to the boom in order to reduce its area in strong winds.

On large straight-rigged sailing ships, reefs were taken using reef lines - the flat ends of the cable, which were used to tie the luff of the sail to the reef line. The reef ropes were tied in such a way that at any moment, if necessary, they could be untied or, as the sailors say, “torn apart.” A reef knot was used for this purpose. It is very similar to direct knot, except that when knitting the second half-knot, its running end is threaded into the loop folded in half. When you pull on the running end, the knot instantly unties.


Rice. 94. Reef Knot

In maritime affairs, this knot is used for tying the tarpaulin covers of lifeboats, winches, compasses and other instruments on the upper navigation open bridge.

This knot is known in everyday life as a “knot with one bow.” It is familiar to everyone; many tie their shoelaces with it. In principle, this is a simple and useful knot.

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 ... >>

Video glasses for gamers and moviegoers 28.03.2002

A new model of Olympus' Eye-Trek Face-Mounted Display series of video glasses is designed for both PlayStation 2 players and DVD players.

The FMD-220 features two 180000-pixel active-matrix LCD screens that give you the feeling of viewing a 52-inch screen from a distance of 2m. Unfortunately, the video glasses only work with three models of DVD players: Matsushita DVDPV220, Pioneer PDV-40 and Toshiba MED20AS.

An additional accessory is a special protective cover, which almost completely excludes the penetration of light from the outside.
