Where is left-hand traffic used?

In 62 countries around the world, vehicles move on the left side of a street or road. Such a movement is legalized in Southeast Asia, Japan, India, South Africa, Kenya. In addition to England, in Europe they drive on the left side in Ireland. Sweden switched to right-hand traffic only in 1967.

Random interesting fact from the Great Encyclopedia:

When was the silkworm first used?

Silk is a thread or fabric made from the finest web of the silkworm, a type of caterpillar. And the cobweb is the cocoon that the silkworm spins in the process of its development into a moth. The secret of making silk thread and fabric was known to the Chinese about 4000 years ago.

There is a legend that the young Chinese Empress Xi Lin Chi accidentally dipped a caterpillar cocoon into the water and discovered that the cocoon's shiny threads could be unwound. She is said to have experimented with growing silkworms and using silk thread to make cloth.

For hundreds of years, the Chinese have kept the secret of growing silkworms and making silk. Merchants from other countries came to the Chinese border to acquire precious silk products and other goods. For some time in ancient Persia and the Greek islands, silk garments were unraveled and re-woven with a different pattern.

The secret of silk production came to Japan around the third century AD. In 550, the Byzantine emperor Justinian sent two Persian monks to China to bring silkworm eggs in a bamboo cane. This episode was the beginning of the development of the silk industry in the vicinity of Constantinople. From here silk production gradually spread throughout southwestern Europe. Italy is famous for its fine brocade, damask and velveteen, made from silk grown in Italy.

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 ... >>

Prospects for the development of smart watches 03.08.2013

Many analysts believe that at first, such devices will be used to monitor the health of the user. The watch can measure the user's blood pressure and pulse by transmitting the data to a smartphone. Foxconn introduced a similar technology last month. However, there are various fitness bracelets even now.

Obviously, smartwatches will offer more functionality. In particular, they can act as a companion device for a smartphone or tablet. Various notifications can be displayed on the watch screen, saving the user from having to get their smartphone out of the bag, which is quite problematic, given the dimensions of modern devices. "It's much more convenient to just look at your wrist and see phone calls, messages, tweets or other notifications on your watch," says Angela McIntyre, analyst at Gartner. In addition, with the help of "smart" watches, you can control some of the functions of the smartphone: music playback, turn the silent mode on or off, and so on. Angela also believes that smart watches may have a built-in microphone for voice commands and for "quick" answers to phone calls.

However, the watch can act not only as a companion device, it can also function independently. In particular, according to rumors, Microsoft is preparing its own version of a smart watch that will have a built-in LTE module and run on a modified Windows 8. However, the analyst sees a problem here, because the user will have to buy a separate tariff plan for the watch, which is impractical.

Surveys have shown that on average, people check their smartphones 20 times per hour. "People are constantly checking their smartphones, but it would be easier to check their watches. There is a user interest in smartwatches that are lightweight and comfortable," McIntyre said.

Analysts also believe that many well-known watch manufacturers will want to participate in the production of "smart" watches. This will also be useful for electronics manufacturers, as for many users, a watch is a fashion accessory, not a functional device.
