Focus Description:

First, the magician declares that he has a "trained headscarf". Of course, no one believes him. But he insists on demonstrating his abilities. To do this, he goes to the public. In this case, you need to hold an ordinary handkerchief and a stick in your hands. At first glance, these items are completely ordinary.

The magician holds the wand vertically, covers it with a handkerchief. The tip of the stick falls just in the middle of the handkerchief. Then he takes one corner of the handkerchief in his hand and begins to twist the handkerchief around the stick. At the same time, he slightly rotates the wand. After a while, the handkerchief will straighten itself out and will spin around the stick.

Focus secret:

The secret of this trick is very simple. First you need to make a special wooden stick, the length of which is about 40 cm. A thin straight needle needs to be driven into one end. She is wearing a scarf.

With enough practice, you can easily make the handkerchief spin on a stick.

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 ... >>

Swimming improves children's vocabulary 21.07.2021

A study by researchers at the University of Delaware suggests that exercise can increase children's vocabulary.

Children between the ages of six and 12 were taught new words, after which they went in for swimming, CrossFit or coloring pictures. Swimmers scored 13% better on subsequent vocabulary tests. Lead researcher Maddie Pruitt, a college swimmer, is not surprised by the results.

"Motor movements help memorize new words. Exercise increases levels of brain-derived neurotrophic factor, a protein important for cognitive function," Pruitt notes.

Why didn’t they have a similar effect when doing crossfit? The scientist explains this by the amount of energy that the brain needs with each exercise. Swimming is an activity that kids can do without much thought or instruction. It's more automated. And CrossFit exercises were new for children. First, they needed to learn the movements, which used up mental energy.
