Focus Description:

The child is shown a deck (or part of a deck) of cards. He chooses a card (let's say 10 of spades) and shows it to the magician. Then the magician says something like: "Go to the living room, take the book 2 rows, counting from the bottom, 3 in a row, counting from right to left and open page 122."

The child opens the book and there is a note: "I knew that you would choose 10 spades!".

Focus secret:

Even before the trick begins, different notes are placed in different books: “I knew that you would choose the queen of spades”, “I knew that you would choose the king of tambourines”, etc. The main thing is not to forget during the trick where this or that is hidden a note.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Heatwaves became more frequent and lengthened 08.07.2020

Scientists at Australia's Center of Excellence for Climate Extreme Research said that since the 1950s, global heatwaves have increased in both length and frequency across almost the entire planet.

The first comprehensive global assessment of heat waves showed that since 1950 they have become more frequent and longer across the planet. The results of the study made it possible to obtain a new metric indicator of the total amount of heat. He showed how much heat is contained in individual heat waves and seasons. As the researchers expected, this number is growing.

For example, during the hottest season in Australia, the temperature increased by a total of 80°C. In the Mediterranean, the most extreme seasons were up to 200°C hotter than the "normal" seasons.

“Over the past 70 years, we can see more and more heatwaves around the world. But now this trend has accelerated noticeably. If we add up the temperature, we can see that the heat around the world has increased by 1°C-4,5°C degrees. In some countries, it has increased by 10 ° C "- lead author of the study Sarah Perkins Kirkpatrick.

The only heat wave metric that does not show acceleration is heat wave intensity. However, this is due to the fact that there are more hot days around the world, and heat waves have become longer. When measuring the average temperature in longer thermal waves, any changes in intensity are almost imperceptible.

For example, in the Mediterranean there was a sharp surge in heat waves. In the period 1950-2017, there was an increase in heat waves by two days per season. However, between 1980 and 2017, this increased to 6,4 days per season.
