Focus secret:

The cucumber is not a real one, but a dummy skillfully made from papier-mâché, painted to match the color of the cucumber. In the cavity of this “cucumber”, a section of which is shown in the figure below, a lead pellet rolls freely.

It is enough to tilt the “cucumber” a little - and the pellet will roll inside it to the bottom. Rolling to the very bottom of the cavity, the pellet with its weight not only controls the downward movement of the “cucumber”, but also turns it over.

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 ... >>

Named the new height of Everest 09.12.2020

The heads of China and Nepal, Xi Jingping and Bidhya Devi Bhandari, officially announced the new height of Everest.

"I would like, together with President Bhandari, to officially announce to the world on behalf of China and Nepal that the height of Everest is 8848,86 meters," the Chinese leader said in a letter.

Earlier Tuesday, a video conference was held with the participation of the foreign ministers of the two countries, at which new data obtained by Nepalese and Chinese researchers were announced.

The Department of Geodesy of the Ministry of Land Management of Nepal assures that the measurements are accurate to the centimeter. The error of the new data on the height of Everest, obtained by comparing data from the GPS and Beidou satellite systems, is plus or minus two cm.

Recall that an agreement on the joint measurement of Everest was reached last year during Xi Jinping's visit to Nepal. Such a need arose after the assumptions of a number of scientists that the mountain could have decreased due to earthquakes in 2015.

Nepal and China disagreed over the height of Everest back in 2015. Countries called different heights of the peak and because of this they could not sign the border protocol.
