Focus Description:

Choose a spectator whose power matches yours, and tell him that now you will demonstrate such a power of magnetism that he will not be able to resist it.

Demonstrating this, you bend your arms at chest level, connecting the tips of your index fingers. Hold them for a few seconds to show the power of "magnetism".

This is a very convincing demonstration because you are not doing any grips, just putting your fingertips together while the viewer is applying all their strength. And he can't separate his fingers.

Focus secret:

It all depends on the position of the hands. By pressing your fingertips tightly together and clenching your arms at the elbows, you gain a great advantage, and the force you apply far exceeds the efforts of a spectator seeking to separate your hands.

By this method, a comparatively weak person can demonstrate more strength than a strong man, and it seems that the person trying to separate your hands has lost all strength. It seems simple, but it really isn't.

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 ... >>

XNUMXD water vapor screen 18.04.2014

Scientists and engineers at the University of Bristol have developed an original desktop display that uses water mist instead of a screen. The display is capable of displaying XNUMXD shapes and could change the way humans and computers interact.

The resolution of the "fog screen" is not high, but it has great potential and is still easier to implement and use than immersive virtual reality technologies.

The new screen is a suspension of tiny drops of water in the air, onto which a three-dimensional or flat image is projected using a projector. Users can not only look at the picture, but also rotate it, drag it, "pass" it to each other with simple hand movements. The screen allows you to display two-dimensional images, while the absence of obstacles for hands facilitates interaction with the picture.

The table itself is a simple structure, consisting of a fog machine (water tank and fans), a projection screen, video cameras and projectors that create a kind of interactive whiteboard on the surface of the table. This board demonstrates two-dimensional images that can be "pulled out" from the screen and "hung" in the air - that is, use the projection on the water mist.

The developers note that their screen facilitates the collaboration of several people who have to exchange various data in the form of tables and three-dimensional images. Users can see each other's activities and quickly communicate the necessary information. Switching between individual and group work is also significantly accelerated. Such opportunities can be useful to the military or employees of emergency response headquarters.

The new desktop display will be presented at the end of April at the international conference ACM CHI 2014.
