Exams in which subject were canceled in Soviet schools in 1988?

After the start of perestroika and the proclamation of glasnost in the USSR, a reassessment of historical events began. A wave of publications in the media on previously forbidden topics that contradicted what was written in textbooks led to the fact that in 1988 school history exams were canceled altogether.

Random interesting fact from the Great Encyclopedia:

Why is it colder in the mountains than in the lowlands, although they are closer to the sun?

The sun heats the earth's air indirectly. Its radiation passes through the layers of the atmosphere and is absorbed by land and water on the surface of the planet, and only then the air receives thermal energy from them. Therefore, although the mountains are closer to the sun, they are colder than on the plains, since on average, for each kilometer of elevation, the temperature decreases by 6 ° C due to the adiabatic expansion of air. But even at the highest altitudes, valleys can be found, which, due to the special relief and the reflection of the sun's rays from the snow, can heat up well. For example, in the so-called Western Circus, which is located on one of the routes to the peak of Everest at an altitude of more than 6 meters, on sunny, calm days, the temperature can rise to 000 ° C.

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. ... >>

Jellyfish robots to clean up the oceans of debris 02.05.2023

Scientists within cybernetics are often inspired by creatures of nature. So this time, inventors from the Institute of Physics of the Max Planck Society (Germany) hit me with jellyfish. The result of this inspiration is a jellyfish robot that can remove debris from delicate ocean environments like coral reefs.

The new works are no bigger than the palm of a hand and consist of six actuators filled with artificial muscles. These muscles are filled with oil sacs covered with electrodes, and when current is applied they receive a positive charge. They then discharge current into the surrounding negatively charged water, causing the oil in the sacs to move around and cause the robots to oscillate.

This whole process creates a plunger-like flow in the water and lifts up small particles picked up by the robot. Thanks to this, the robotic jellyfish is not only able to collect garbage and filter water, but is also able to capture small biological samples such as fish eggs. At the same time, the mechanism does not pollute the environment at all and is completely silent.

However, the remarkable robot has one serious drawback: it is connected to a power source using a wire, which seriously limits its mobility.

The research team is already working on a battery operation pattern so that the mechanism can move in any direction. And in the future, such jobs could do housework in the ocean and purify the water.
