In real life, we have long been accustomed to guessing the center of gravity of each object. We immediately figure out how to put or place this item so that it does not fall. "Фокус"Vstanki-Vstanka is that he deceives our eye. His center of gravity is not where we expect. Therefore, the Roly-Vstanka so stubbornly takes positions that seem unnatural.

Let's do one more experiment - which at first glance also contradicts the laws of equilibrium. From thick paper or thin cardboard, glue the ring. On its inner side, glue a load in one place: a wooden chock, a piece of sealing wax or another small object that weighs more than the ring itself. To prevent the load from being visible, seal the ring on both sides with paper. You can draw something on it, for example, a face. If the chin of this face is where the load is, then it will not be possible to put it "upside down" (although, of course, the face does not have any legs). The "face" will roll until it is chin down. It can even climb up the slope, as shown in the picture. The ruler is placed at one end on the books. Any normal wheel would roll down it. But the "face" does the opposite.

Put it on the ruler at the right, lower, end, but so that the chin is almost at the very top on the left. Let go of the "face" - and it will roll up the ramp!

Up the slope

Of course, it will stop as soon as the chin touches the ruler. After all, the center of gravity will take the lowest position.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

energetic windows 06.04.2011

The Norwegian company Ensol has patented thin-film solar cells, which consist of metal nanoparticles deposited on glass in a vacuum chamber.

The work is carried out in cooperation with the Faculty of Physics of the University of Leicester (England). By 2016, the firm hopes to achieve 20 percent efficiency in its batteries. Glasses with a solar battery can be used to glaze windows - they will be slightly darkened, but for sunny southern regions this is only a plus.
