Focus Description:

A handful of little things spill out on the table. The magician turns away and asks one of the spectators to turn over the coins one at a time at random, saying "is" at each turn. In this case, the viewer can turn over the same coin several times. Then the viewer covers one of the coins with his palm.

The artist turns to the table and says how the closed coin lies, up with the coat of arms or "lattice".

Focus secret:

Before you turn away, you need to count the number of coats of arms. For each word "is" add one to this number. If the last sum is even, then the number of coats of arms, after the viewer has finished turning over the coins, will also be even; if the sum is odd, then odd.

Looking at open coins, it is not difficult at all to determine how the coin lies under the palm, up with the coat of arms or "lattice".

This trick can be performed with a set of any identical objects that can be placed on the table in one of two possible ways, for example, lemonade bottle caps, pieces of paper, one side of which is marked with a cross, playing cards, matchboxes, etc.

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 ... >>

Magnetic spray creates robots 25.11.2020

Tiny robotic devices require miniaturized electronics, making such mechanisms difficult and expensive to manufacture. Researchers from Hong Kong talked about a new technology that allows you to turn any microscopic objects into robots using a special magnetic spray.

A team of scientists announced the creation of a unique spray, after processing which any objects receive the functions of robots and can be controlled due to magnetic properties. The spray consists of polyvinyl alcohol, gluten and iron particles. It instantly adheres to any objects, regardless of their structure and size, after which a film with a thickness of 0,1 to 0,25 mm is formed on the surface.

After applying the spray, the object is magnetized, depending on how it will be further controlled under the influence of a magnetic field. After the end of the procedure, the researchers get the so-called millirobots with different modes of movement: they can crawl, walk, roll over and roll over various surfaces, from glass and leather to wood and sand.

Any robot can be reprogrammed to get a different mode of movement. During the experiment, it was possible to deliver a medicine capsule into the body of a sleeping rabbit. So far, the protective coating of the robot can withstand no more than eight minutes, but technology has already been developed that allows it to survive in an acidic environment for up to half an hour.

The researchers believe that their robots will be useful for transporting drugs to certain parts of the body, as mobile sensors, and in many other areas.
