Who flew the first kite?

The history of kites is so long that no one today will undertake to name the author of the first kite, or at least the country where he lived. Some argue that it was a Greek named Arkitas who lived in the XNUMXth century AD. e. But in the countries of the East, kites were launched, probably, long before that.

In China, "snakes" have always been an important part of many holidays. On the ninth day of the ninth month of the Chinese calendar, the "High Flying Festival" is celebrated nationwide. The sky has a colorful view, completely dotted with snakes of various shapes and sizes. Some of them are shaped like fish, frogs, birds. This is not only a children's holiday: quite adult people unite in games. There are even "kite battles" in which kites with pieces of glass attached to them are used to cut the strings of other kites!

In Western countries, snakes were used for more serious purposes. In 1752, Benjamin Franklin launched a silk kite into a thunderstorm to prove that lightning and electricity were one and the same. Even before Franklin, kites were flown with thermometers attached to them to study cloud temperatures.

By the end of the 1,6th century, kites were used by most weather stations. They were equipped with devices for recording air temperature and humidity, wind speed. Some of these kites have flown over six kilometers! In order to reach such a height, not one, but several kites connected together were used. The snake thread was made of very thin wire and was so light that it weighed only 7 kg for 110 km, and strong enough to lift XNUMX kg without breaking.

Before the invention of the airplane, kites were also used for military purposes, when balloons made forced landings due to strong winds. For example, one of these kites reached a length of 11 meters and lifted a person into the air by 30 meters.

Although most kites are of the familiar triangular shape, the most powerful kites are box-shaped, completely closed at the top and bottom and partly at the sides. To build a kite in the form of a butterfly, a ship or a bird, one simply takes a greater number of sticks than in ordinary kites and pulls on the threads to obtain the desired shape.

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 ... >>
