Who invented the first plow?

Before sowing, the peasant must plow the land. The plow breaks the earth and turns the soil over. The plow is a very ancient invention and no one knows who made the first plow. The oldest plows that have been found are about 5 thousand years old.

At first, the role of the plow was performed by a branched stick or log, which was dragged across the field by men or women. Later, animals were harnessed to the plow. Gradually, the shape of the stick was changed so that it was more convenient to work. The base was given a pointed shape and called a plowshare. The plow was now easier to pass through the thickness of the earth. Then the sides of the plowshare were bent. They directed the soil to the plow blade and turned it over. The curved sides were called soil rippers. The share and rippers form the base of the plow.

At present, the plowshare type of plow is widespread. Later, the plowshare began to be made of metal, and it became much harder and stronger. In the 1797th century, the British began to make plowshares from cast iron. In XNUMX, American inventor Charles Newbold received a patent for the first American cast iron plow. Modern plows are made of cast iron or steel, depending on the soil being cultivated. Do you know that Thomas Jefferson used his knowledge of mathematics to find the best shape for the base of the plow (share and ripper) and contributed to the fact that the cast-iron plow became common?

For processing dry hard soil, disk plows are used, not share plows. Instead of pointed blades at the base, disc plows have sharp-edged steel discs. Disc plows are good for stony soil, as the discs can roll over rocks that can get plows stuck or fail. Disc plows are also good for plowing grass into the soil to fertilize it.

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. ... >>

Mate significantly increases the risk of cancer 05.03.2022

Tea is one of the most popular drinks in the world. But not every tea is equally good. So a new study has shown that regular consumption of one type of tea can increase the risk of developing several types of cancer.

This is mate tea. Proponents of its use believe that herbal tea helps to overcome fatigue, helps to lose weight, relieve headaches and ease depression. But according to the Mayo Clinic, the evidence to support this is limited.

Studies have shown that drinking the popular herbal drink can have adverse effects. The scientists reviewed data from ten studies that examined the potential risks of drinking mate tea. A study found that regular tea consumption can increase the risk of lung cancer and various types of digestive tract cancer, including esophageal cancer, liver cancer, colon cancer, and stomach cancer. Mate has also been shown to triple the risk of developing esophageal cancer.

Mate, an infusion of the herb Ilex paraguariensis, is very common in some South American countries and has been associated with an increased risk of esophageal cancer. This increased risk may be due to the high temperature of the drink or the potentially carcinogenic pollutants, polycyclic aromatic hydrocarbons (PAHs).
