Focus Description:

On the hand of the magician, the name of the card of the hidden card appears.

Focus secret:

On the hand, we write in advance with soap the name of the top card of the deck. Then we will ask the spectator to take the top card of the deck, look at it and put it in its place. Then we take coffee and rub the place where we painted with soap - the name of the map is displayed.

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 ... >>

Dynamic heads using bamboo and opal analogue 09.03.2014

Panasonic announced the creation of a new dynamic head, the diaphragm of which is made of a material using the so-called "plant opals" - phytoliths, microscopic fragments of amorphous silicon dioxide (SiO2 nH2O), which accumulate during the life of bamboo and many other plants and fungi.

The material has a hardness of 5-6,5 on the Mohs scale, which corresponds to such a mineral as opal (see photo below). Basically, opal has the same chemical formula. The size of phytoliths can be from several hundred micrometers to several micrometers.

In the manufacture of diffusers, in addition to directly phytoliths, bamboo fibers, bamboo charcoal and resin are also used. Thanks to the use of phytoliths, the developers were able to achieve an increase in acoustic velocity by 10%, flexural elasticity by 40% and a decrease in internal loss by 20%. The comparison was made with other Panasonic products made with bamboo materials, but without the addition of phytoliths.

It is worth noting that bamboo was chosen by the company due to the extraordinary growth rate of this grass (up to 0,5-1 m per day), which guarantees the possibility of using this material without harming the environment.
