How did swimming come about?

Man is not given by nature the ability to swim, like many animals. Naturally, man had to learn to swim by observing animals that swim by instinct. The first man was forced to learn to swim in order to survive in harsh conditions.

The first method of swimming that a person mastered is known as "dog rowing", that is, imitating the swimming of a dog. But then a person wanted to find a way of swimming that would give him more opportunity to coordinate the movements of his arms and legs, as well as the ability to stay on the surface of the water for a long time. And now, more than two thousand years ago, man mastered a new type of swimming, known as breaststroke. This species is still used by many people to cover long distances in open choppy water.

The next type of swimming that man learned was lateral. In it, the movement of the legs resembled the swing of scissors. Then the man learned to swim with saplings. This type of swimming allowed to develop greater speed. The next type of swimming was named "trudgeon", named after the Englishman John Trudgen, who invented it in 1783. This style consists of alternating arm strokes and scissor kicks. John Trudgen set many swimming records using this style and many people adopted it.

The next style we come to is the crawl style. It is so named because it is very similar to crawling. It was brought to England in 1902 by Richard Cavill, who learned it in Australia where the style was widely used by the locals. At first it was called "Australian rabbit". People who swam with this style set so many records that the front crawl was recognized as the fastest among all swimming styles.

Swimming was highly valued in ancient Greece and Rome and was seen as part of the training of warriors.

How did the English language come about?

Almost all modern languages have their original language from which they originated. This original language, with all its derivatives, constitutes the "seven" of languages.

English belongs to the Indo-European group of languages. It also includes French, Italian, German, Norwegian and Greek.

There are various subgroups within the Indo-European group, and English belongs to the West Teutonic subgroup. In fact, the English language has its origins in the middle of the fifth century, when the Celtic tribes were invaded by newcomers from across the North Sea, who conquered the entire territory of modern Great Britain.

For convenience, the history of the English language is divided into three main periods: Old English (Anglo-Saxon) - 400-1100 years Middle English - 1100-1500 years Modern English - from 1500 to the present.

Initially, Celtic was spoken in England. However, after the Anglo-Saxon conquest of the islands, very few Celtic words remain in modern English.

The Anglo-Saxons spoke various dialects. Later, after the invasion of the Normans, elements of the Scandinavian language appeared in the language. This language, belonging to the Germanic languages, also influenced the English language.

In 1066, William the Conqueror declared Norman French the language of his court. Initially, the "Norman" language spread among the most prosperous segments of the population. Gradually, this language became more widespread, and a new language appeared, different from Anglo-Saxon. This language was the basis of modern English.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Dental prosthesis in the service of linguistics 17.04.2009

Christophe Jeannin, an engineer at the Institute for Verbal Communication in Grenoble, France, has built electronic sensors into dentures to record tongue movements as they speak.

The data obtained will improve the formulation of French pronunciation among foreigners. True, such studies can only be carried out on people who need dental prosthetics, and their pronunciation is often not perfect.
