Focus Description:

Show the audience one by one 10 sheets of paper on which the numbers from 1 to 10 are written in random order: 9, 1, 2, 8, etc. Put the sheets in two identical bags - five in each. Invite two spectators, without taking out all the sheets, to randomly take one sheet from each package so that you do not see what number is written on them. Have them show these numbers to the others.

After that, give the spectators the packages. Turning their backs to you, each of them takes out all the sheets from the bag, attaches the one that took them to them, mixes them and puts them in the bag, then passes it to you. Take the sheets first from one package, then from another. After carefully examining them, show the audience the two sheets that they took out of the packages.

Focus secret:

The sheets are pre-folded by you, so the order of the numbers only seems to be arbitrary. In fact, five sheets of numbers come first, the names of which begin with letters from the first part of the alphabet, up to and including "o": 8, 2, 9, 10, 1. The rest of the numbers are written on the other five sheets. In each part, the order of numbers is really arbitrary.

When you put five sheets into packages, then the first group of numbers falls into one, and the second into the other. At the moment when the audience shows the drawn numbers to the audience, you change the packages imperceptibly. Each of the spectators puts the leaf in another bag. As a result, their sheets with numbers will be among other groups of numbers and it will be easy for you to find them.

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 ... >>

eSIM will replace regular SIM cards 25.03.2024

The international association of mobile operators GSMA shared its forecast regarding the spread of eSIM in the near future.

eSIM is becoming an increasingly common and popular solution in the world of mobile communications. GSMA forecasts indicate significant growth in eSIM usage in the coming years, which could change the face of the mobile technology market.

Despite the fact that embedded SIM cards were introduced about 10 years ago, they remained not very popular for a long time. From 2016 to 2018, they found their use mainly in smartwatches. However, smartphones are currently the main consumers of eSIM, occupying about 60% of the market.

The GSMA predicts that the number of eSIMs in use will reach 2025 billion by 1, rising to 2030 billion by 6,9, representing approximately three-quarters of all smartphone connections, according to the organization.

GSMA is paying special attention to smartphones that do not support the installation of a physical SIM card. Particularly rapid distribution of built-in SIM cards is planned in the United States, where, starting in 2022, smartphones of the famous brand are sold exclusively with eSIM.
