How was the modern method of shot production invented?

The modern method of shot production was invented in 1872 by William Watts, a plumber from Bristol (Great Britain).

At that time, pellets were either cast one by one in molds, or chopped from thick lead wire and then rolled in a rotating drum to a rounded shape, or molten lead was poured from a small height into a barrel of water - drop-shaped pellets were obtained.

So, once Watts dreamed of a rain of spherical drops of water. When he woke up, he realized that it was necessary to pour molten lead from a sufficiently high height in a special tower with a water pool below. Along the way, the lead drops will become almost perfectly spherical.

Since then, the fraction has been doing so.

How does a kangaroo jump?

Kangaroos are one of the strangest and most ancient animal species on Earth. We know that hundreds of thousands of years ago there was a species of kangaroo almost the size of a horse! Today, kangaroos can be found in Australia, which is sometimes called "Kangaroo Country", and the image of a kangaroo is even on the coat of arms of this country.

The kangaroo is the most famous of the marsupials. A mother kangaroo carries her cubs in a fur sack located between her hind legs on her stomach, and feeds them there. Kangaroos live in this bag for quite a long time.

At birth, a kangaroo is a tiny, pink, hairless lump of just over an inch! Mom puts him in a bag immediately after birth, and the cub is completely helpless for some time. But by the age of six months, he already reaches the size of a puppy. He moves around in a bag, sticking out only his head.

When the mother stops to eat tree branches, the young kangaroo also picks the leaves and eats itself. Even after the kangaroo has learned to walk and run, he likes to stay in a warm, safe bag. And when danger threatens, the mother jumps up to him, grabs him with her lips without stopping, and gently lowers him into the bag. An adult kangaroo can be up to two meters tall. It has short front legs and very long hind legs. These powerful hind legs allow the kangaroo to jump from 3 to 4,5 meters in length! To support and maintain balance while jumping, the kangaroo uses its large, long tail.

In Australia, kangaroos are hunted because they destroy crops. Their meat is eaten, and a good, strong skin is made from the skin. Protection against danger for kangaroos is their speed and keen hearing, which allows them to hear an approaching enemy from afar.

When a kangaroo is baited by hunting dogs, he can grab the dog with his front paws and kill him with one blow from his hind paw!

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. ... >>
