Focus Description:

The magician makes the match float vertically.

Focus secret:

If you cut off the head of a pin and stick it with its tip all the way into the end of a match, then such a match will float vertically in the water, as if standing.

No one else in the audience has such matches, so no one but you can make the matches float in such an unusual way.

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

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 ... >>

The structure of the brain sets some personality traits of a person 27.01.2017

An international group of researchers from the UK, USA and Italy compared data on the structural features of the cerebral cortex and personality traits and found a relationship between these two parameters.

The authors of the study used data collected as part of the Human Connectome Project. But they focused their attention not on physiology, but on the anatomical features of the brain, namely the thickness of the cerebral cortex, its area and the volume of folds. In total, the data of about 500 people were studied.

The same people completed the Big Five personality traits questionnaire: neuroticism/stability, extraversion/introversion, openness to experience/conservatism, cooperation/competition, conscientiousness/impulsivity.

The researchers found that a high level of neuroticism, which predisposes to the development of neuropsychiatric disorders, was associated with increased cortical thickness, as well as a decrease in its area and volume of folds in some areas of the cerebral cortex (prefrontal temporal cortex).

On the contrary, openness to new things turned out to be associated with the opposite picture - a decrease in thickness, an increase in the area and volume of folds in some areas of the prefrontal cortex.
