Focus Description:

The magician shows the audience an ordinary handkerchief. Then he takes a frame from the table, pins a scarf to it with pushpins and wraps it all in paper. Then he takes some object, for example, a pencil, and pierces the paper through and through in several places. Finally, he unfolds the paper, and everyone sees a whole handkerchief.

Focus secret:

The secret of the focus is in the frame. A secret moving bar is made in it, one edge of the scarf is attached to the frame during the demonstration of the focus, and the other to this moving bar. By wrapping the frame in paper, you will be able to discreetly lower the bar to the opposite end of the frame. After that, pierce the paper as much as you like and anywhere.

Well, in conclusion, manipulating in the same way, return the handkerchief to its original place and show the audience the whole handkerchief.

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 ... >>

Implanted brain stimulator 30.04.2024

In recent years, scientific research in the field of neurotechnology has made enormous progress, opening new horizons for the treatment of various psychiatric and neurological disorders. One of the significant achievements was the creation of the smallest implanted brain stimulator, presented by a laboratory at Rice University. Called Digitally Programmable Over-brain Therapeutic (DOT), this innovative device promises to revolutionize treatments by providing more autonomy and accessibility to patients. The implant, developed in collaboration with Motif Neurotech and clinicians, introduces an innovative approach to brain stimulation. It is powered through an external transmitter using magnetoelectric power transfer, eliminating the need for wires and large batteries typical of existing technologies. This makes the procedure less invasive and provides more opportunities to improve patients' quality of life. In addition to its use in treatment, resist ... >>

The perception of time depends on what one is looking at 29.04.2024

Research in the field of the psychology of time continues to surprise us with its results. Recent discoveries by scientists from George Mason University (USA) turned out to be quite remarkable: they discovered that what we look at can greatly influence our sense of time. During the experiment, 52 participants took a series of tests, estimating the duration of viewing various images. The results were surprising: the size and detail of the images had a significant impact on the perception of time. Larger, less cluttered scenes created the illusion of time slowing down, while smaller, busier images gave the feeling of time speeding up. Researchers suggest that visual clutter or detail overload can make it difficult to perceive the world around us, which in turn can lead to faster perception of time. Thus, it was shown that our perception of time is closely related to what we look at. Larger and smaller ... >>

Dirty air makes people stupid 01.09.2018

According to a new study by scientists in the US and China, prolonged exposure to polluted air affects human cognitive performance.

To investigate the link between air pollution and cognition, the researchers turned to the results of the China Family Panel Studies, an annual test of Chinese citizens that includes verbal and mathematical tests of cognitive performance. The scientists especially focused on the results obtained from 2010 to 2014 in 162 randomly selected Chinese regions. In total, about 20 people participated in the study in this way.

They then used official air pollution data to calculate how much a person was exposed to it between inspections. So scientists were able to determine how dirty air affects the human intellect.

The results were rather unpleasant, especially in the case of older people. “We already understand that air pollution can reduce the level of education for a whole year, which is a huge figure,” says Qi Chen, one of the researchers. “But we also found that this effect is even more pronounced in older men over 64 and with low level of education. If you calculate the cognitive losses for them, then there the number goes on for several years. "

Researchers do not yet know why pollution has such an effect. But they are sure that it causes mental decline - that is, it is not just a correlation between the two indicators. Perhaps the whole point is that such air adversely affects the white matter in the brain.
