What secret did the Chinese keep more than their eyes?

Now everyone knows everything about silkworm butterflies and the silk threads they secrete. But only the Chinese realized almost five thousand years ago to domesticate the silkworm and with its help to establish the industrial production of luxurious and durable silk, the favorite material of fashionistas and fashionistas of all times and peoples. No less surprising is the fact that for centuries the Chinese managed to keep the secret of silk production.

It was the greatest secret! For its disclosure was punished by death. It is difficult to say how many foreign merchants paid with their lives trying to take the "golden" silkworm out of China. Where and how they were not hidden by cunning foreigners and once they were almost taken out of Sichuan province in a bamboo staff! But even there meticulous Chinese customs officials discovered smuggling! True, this was far from the only achievement of the Chinese. The first compass appeared in China. Scientist Zhang Heng (78-139 years) designed the first seismograph, a celestial globe, described two thousand five hundred stars.

Even before our era, Chinese astronomers were the first to record the appearance of Halley's comet and discovered spots on the Sun. The Chinese invented the iron shovel and crossbow, paper, fragile porcelain and formidable gunpowder. The Chinese were the first to invent paper money.

What does the brand of soda water Boga, popular in Tunisia, have to do with Russia?

One of the popular brands of sparkling water in Tunisia is "Boga". Its history goes back to the appearance in this country of the ships of the Black Sea Fleet with Russian emigrants - the remnants of Wrangel's army. At first, Russians were generally forbidden to go ashore under the pretext of quarantine, and local residents set up a business to deliver food to ships. Seeing the ship's barrels with the inscription "Water", the merchants decided that these were the Latin letters "Boga" familiar to them, and under this name they began to supply fresh water.

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 ... >>

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. ... >>

wheat ice cream 17.06.2002

Studying the reasons for the cold hardiness of winter wheat, biochemists from the University of Guelph in Canada found a special protein in the plant.

When the temperature drops below zero, it covers the surface of the formed small ice crystals and prevents their further growth to large acute-angled crystals that would break the cells, thereby killing the plant. But the same problem arises in the manufacture of ice cream.

The smaller the ice crystals, the tastier it is. Therefore, scientists have proposed the use of wheat protein as an additive in ice cream. One-tenth of a milliliter per liter of ice cream mixture is enough, and it turns out to be especially soft in taste.
