Domino chain with a break. The Secret of Focus

Directory / Spectacular tricks and their clues

Focus Description:

The magician writes down the prediction on a piece of paper and puts it aside. The dominoes are mixed and then laid out in a chain, placing identical ends next to each other, as is done in a regular game of dominoes. After completing the layout, look at the number of points at each end of the chain.

They take out a piece of paper, and it turns out that these two numbers are written there! The trick is repeated several times, with new numbers predicted each time.

Focus secret:

This trick is obtained because any chain made up of all dominoes without exception (there are usually 28 of them) has the same number of points at the ends, because the number of bones containing a given number of points on one of the halves is even (if you do not take into account attention of the double), and inside the chain such dice are arranged in pairs.

Before starting the trick, the artist quietly hides one bone, and writes down the numbers of points at the ends in a prediction. Since laying out all 28 tiles should form a closed chain, the missing tile will indicate the number of points at the place where it was broken.

The bone to be removed must not be a duplicate.

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 ... >>

Efficient installation for energy storage in compressed air 04.10.2022

Compressed air energy storage systems are nothing new. The problem was their relatively low energy efficiency, which Chinese scientists successfully solved. Based on the development in Hebei Province, the world's most advanced 100 MW air-compression energy storage system has been created, tested and will be put into commercial operation by the end of the year.

The world's first CAES (compressed air energy storage system) project on a utility scale was implemented in Germany in 1978. The plant is still in operation today, providing an output power of 290 MW. CAES equipment pumps atmospheric air into voids in the ground, compressing the air to a pressure of about 140 atmospheres. The efficiency of the German installation is 40%, which is significantly lower than pumped storage power plants with energy reserves in the process of pumping water masses to a great height (efficiency up to 75%) and battery storage, the efficiency of which reaches 90%, but is realized in the course of the most serious financial injections.

In the process of compressing air, a CAES unit releases a lot of heat energy. The German project does not use this heat, and when releasing compressed air, it uses fossil fuel combustion to heat it, which in combination greatly reduces the efficiency of the solution (additional heating greatly increases the pressure of the outgoing air flow and enhances the work it does - the rotation of generator turbines).

Chinese engineers have learned how to capture and efficiently store the heat generated in the process of air compression and then reuse it to heat the air supplied to the turbines. According to the test results, the heat storage efficiency is maintained at 98,95% after eight hours and 98,73% after 16 hours, which is the highest among existing CAES heat storage devices.

In parallel, other projects are being implemented in China on systems for collecting energy from renewable and therefore unstable energy sources, such as the sun and wind. For example, a 100 MW storage system based on vanadium flow batteries is being built in Dalian, and energy storage projects have been launched in Inner Mongolia, Ningxia and other regions, both in conventional lithium batteries and in more exotic options, such as using flywheels. China is striving to become a leader in energy storage and is testing all possible options to achieve its goals.
