Comments on the article
People have long dreamed of flying. Make wings like birds, insects, bats. How many different living creatures are carried in the air, but a person cannot!
Bold inventors tried to make wings for people. But no one could fly on such wings. The man did not have enough strength to lift himself into the air. At best, the inventors managed to land safely on the ground, gliding on their wings from a mountain or a high tower. This did not require force.
You must have made paper doves more than once. One of the simplest and at the same time well-flying is the "arrow". She needs a sheet of paper measuring 295x176 mm. Fold this sheet in half along the long side. All other dimensions and folding order are clear from the figure.
"Arrow" is good to start in the room, and even better from the balcony of a high house. Then she can fly far. And if it gets on the road into an upward flow of air, it can even rise up. It is a pity that there is no pilot on the "strelka". He would specifically look for ascending currents and circle in them, rising higher and higher with the air. This is how glider athletes fly on their light, non-motorized devices.

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. ... >>
Random news from the Archive Dangerous hydroelectric power station
16.08.2012
Hydroelectric power is generally considered to be "environmentally friendly". In fact, nothing is burned here, the air is not polluted and no waste remains.
However, the case of the Chinese Three Gorges hydroelectric power station on the Yangtze River, the most powerful in the world, casts doubt on the harmlessness of hydroelectric power stations. Although the hydroelectric power plant should finally be put into operation only at the end of 2012, when the last three turbines will start working, the unpleasant consequences are already clear. A reservoir of 1080 square kilometers formed in front of the dam sank 13 cities and 466 villages, and 1,3 million people had to be relocated. After the construction of the dam, the water of the Yangtze became undrinkable, as toxic microalgae multiplied in the stagnant water of not only the river, but also its 22 tributaries.
The existence of the rarest species of animals - the river dolphin and several species of fish - is under threat. At the bottom of the reservoir, silt and sand brought by water are accumulating faster than expected. Over the next ten years, at least $27 billion will have to be spent on mitigating these consequences. This is four billion more than the cost of the construction itself.
