Where are most of the world's soccer balls made?

80% of all soccer balls in the world are produced in Pakistan, with three-quarters of them in the city of Sialkot. A significant number of these balls are made using child labor, although this problem has been addressed in recent years.

 Random interesting fact from the Great Encyclopedia:

Why is the north shown on maps at the top, and where are they trying to break this tradition?

Early cartographers needed to have a fixed direction associated with a fixed object in order to draw geographic maps. Such an object is the North Star, which in our time points north. That is why on the maps they traditionally began to depict the north at the top, and the south at the bottom. Recently, in the countries of the southern hemisphere, such as Australia or New Zealand, inverted cards are popular, with the south at the top. They are also used in other parts of the world as tools for teaching critical thinking.

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 ... >>

Samsung is preparing to release flexible displays 25.11.2012

In the first half of 2013, Samsung intends to start mass production of the so-called flexible displays. With a plastic backing, they are stronger, lighter, and cheaper than modern displays that use glass as a base. Samsung Display is preparing to mass-produce displays with a plastic base instead of glass, which will make devices stronger, lighter and even more flexible, according to the Wall Street Journal, citing a source familiar with the situation.

The displays will be based on OLED technology, meaning they will use LEDs. This technology is used in displays for Samsung's flagship smartphones and is gradually beginning to be introduced into TVs. OLED technology allows the construction of thin panels that, using plastic as a base, can be bent without destroying the electronics. In addition, such panels are lighter in comparison with modern panels, which are based on glass.

The development of flexible OLED panels has been going on for the past few years. In addition to Samsung, Japanese companies Sony, Sharp and Korean LG Display participate in it. For example, Sony Corporation has been in this field since 2002. Two years ago, Sony showed off a 4,1-inch flexible LED display that it developed. However, there are no commercial devices based on such displays yet, due to technological limitations in mass production.

"Samsung's main goal is to use plastic instead of the traditional glass substrate to create shatterproof displays. This technology can also help reduce product costs and differentiate products in the market," said Lee Seung-chul, an analyst at Shinyoung Securities.

The WSJ writes that Samsung Display is currently in the final stages of developing flexible displays. It is planned to release them on the market in the first half of 2013, and the company expects to become their first manufacturer. Samsung Display Vice President Lee Chang-hoon said the company is shipping test samples of flexible displays to several of its partners today. However, he could not name the exact date for the release of the first products based on them, since it has not yet been determined. Previously circulated information that the Samsung Galaxy Note II will be equipped with a flexible display.
