Focus Description:

Remove some of the matches from the matchbox. Invite a willing viewer to think of any number from the second ten. Let the numbers of this number be added together. When you are called the result, return this number of matches back to the boxes.

If now the viewer counts all the matches in the box, then their number will be equal to the intended number.

Focus secret:

Nine matches must be left in the box - the rest of the matches are removed. Whatever number the audience has in mind, the sum of its digits (if 9 is added to it) will be equal to the intended number. For example: they thought of the number 17. 1 + 7 = 8. Return eight matches back to the boxes. 9 + 8 = 17.

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 ... >>

Unmanned robots will charge electric vehicles 22.12.2019

Volkswagen has developed a technology that will allow owners of electric vehicles to charge their cars anywhere, including places located far from power outlets. Instead, a mobile battery will be used.

According to the idea of ​​Volkswagen Group Components engineers, charging terminals for mobile batteries will be located in the parking lots. These batteries will be moved by an unmanned robot, which will roll the battery to the car, connect it and disconnect it at the end of the charging process, in order to then deliver the battery to the charging site.

Each battery has a capacity of 25 kWh and supports charging up to 50 kW. Owners of electric vehicles will be able to invite charging robots either through a mobile application, or the robot will independently detect a vehicle that needs charging and connect it to the battery.
