Focus Description:

The magician offers students the following actions:

The first viewer thinks of some two-digit number, the second one assigns the same number to it on the right and left, the third one divides the resulting six-digit number by 7, the fourth one by 3, the fifth one by 13, the sixth one by 37 and passes on his answer to the thinker, who sees that his number has returned to him.

Focus secret:

If the same number is added to the right and left of any two-digit number, then the two-digit number will increase by 10101 times. The number 10101 is equal to the product of the numbers 3, 7, 13 and 37, so after dividing we get the intended number.

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. ... >>

New proof of string theory 23.09.2020

American mathematicians managed to find one more proof confirming string theory. To do this, scientists from the Utah Institute examined two-dimensional K3 surfaces, the results of the work gave an improved understanding of how strings can interact in space-time.

String theory is usually called universal because it is able to combine quantum mechanics and Einstein's general relativity. According to this theory, there are some vibrating fibers that permeate the universe. They regularly interact with each other, explain the nature of fundamental processes, but scientists have nothing but indirect evidence of their existence.

The new evidence is likewise classified as circumstantial. The scientists investigated the delamination and multidirectionality of compact K3 surfaces to improve understanding of how strings interact with each other in spacetime. Mathematicians believe that string theory can be used in calculations for an in-depth understanding of the physical processes in the universe.
