Directory / Spectacular tricks and their clues

Focus Description:

Invite those who wish to memorize any numbers. Then say your number, like 7. Next, tell them that if you add them and your number together, and the viewer has an even number, the result will be an odd number. If his number is odd, then the number will become even, although you do not know the intended number of the viewer.

Ask the viewer what number he has, even or odd? When you count all the numbers, then their total number will be, as you warned in advance, the opposite of the first. Repeat the trick with other people who wish - the result will be the same.

Focus secret:

If you add odd to even, you get odd, and if you add odd to odd, you get even. It is only necessary that any of your digits be always odd. This arithmetic trick can be shown to friends, acquaintances and by phone. There will be no error.

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 ... >>

Testosterone and sports 11.12.2014

It is generally accepted that testosterone helps to win the competition, whether it's a regular yard fight or something noble-Olympic. Indeed, testosterone has been linked to aggressive behavior, increased self-confidence, etc., but does it really help you win in sports? To test this, you just need to assess the level of the hormone in athletes, and then compare it with the distribution of places and medals.

David A. Edwards, Christopher Elliott and Kathleen V. Casto from Emory University (USA) did just that - they compared the level of testosterone in the saliva of those who had to run cross-country, with the results of the run. Samples were taken three times: before the warm-up (warm-up), after the warm-up and at the finish line. As the authors of the work write in their article in The International Journal of Exercise Science, testosterone levels increased in both women and men, and already during the warm-up. At the finish line, testosterone in saliva turned out to be even more, in addition to it, the level of the stress hormone cortisol also increased. However, sports results did not coincide with the hormonal picture. One of the competitors came to the finish line one of the last, despite the strongest jump in testosterone.

A year ago, David Edwards and Kathleen Casto found out that the status of a player in the team could depend on him. The study was conducted among women: those who had low levels of cortisol, but high levels of testosterone, were highly respected. Something similar was reported a year ago on the pages of Psychological Science by psychologists from the Erasmus University of Rotterdam (Netherlands) - they came to the conclusion that this "hormone of aggressiveness" in some conditions promotes cooperation and even noble behavior, which, in turn, cannot not affect the relationship with the person. True, the emphasis of that work was on something else: that the effect of testosterone depends on the social context.
