When and how did chewing gum originate?

In 1850, when the American Thomas Adams put it on sale under the name Chewing gum. It was made from the milky sap of the Sapotel tree (Manilkara zapota), which grows in the jungles of Central America. First, this juice is evaporated, it thickens, then it is mixed with various flavorings (mint, sugar, etc.).

Hundreds of millions of sticks of chewing gum are sold every year.

Why is the UK divided into counties?

The modern division of England, Wales, Scotland and Ireland into counties is the result of a long process of historical, legislative, economic and social change over a thousand years. It began in the time of the Anglo-Saxons, when England was divided into regions, the common name of which "shire" (the Russian transcription of the word "shire") is preserved in the names of many modern counties, for example, Yorkshire, Lancashire, etc.

The division into regions stemmed from the principles of local self-government and self-defense. The Norman conquerors who conquered England in 1066 adopted this system from their predecessors.

Subsequently improved, it gradually reached the areas bordering Scotland and Wales. In Wales, the borders of the counties have changed little since the days of the Tudor dynasty, in whose veins English blood mixed with Welsh. Scotland has for centuries had a system of territories ruled by sheriffs, which was very different from the English. The division of Ireland into counties was carried out by the highest feudal nobility in the time of Henry II and further perfected by Oliver Cromwell 5 centuries later.

Over the past centuries, the map of the British counties has undergone constant changes, reflecting changes in the social life of the country. One of the most important factors causing these changes was the movement of population from one region to another, especially from the countryside to the cities during the "industrial revolution".

The largest cities, in which more people lived than in the rest of the territory of a particular county, were withdrawn from the latter in 1929 and turned into separate administrative units. It also happened that one county "swallowed" another! The creation of the Greater London Region in 1965 resulted in the former county of Middlesex being mentioned only on postal envelopes.

In some counties, two capitals appeared, one of which is a historical, and the other is an industrial, commercial and administrative center.

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 ... >>

Microsoft servers will be equipped with their own processors 27.06.2014

In early 2015, Microsoft plans to move the Bing search engine to servers with FPGA processors. The corporation independently reprogrammed Altera chips for processing Bing requests.

Microsoft has completed testing of servers with FPGA chips, in the programming of which the engineers of the corporation took part. The servers have been configured to serve the Bing service, Wired reports. FPGAs are microchips that can be reprogrammed after production to meet new challenges or specific applications.

In the case of Microsoft, the FPGA chips were produced by Altera, and Microsoft was involved in their development and production at the level of reprogramming. The author of the project, Doug Berger, believes that the new processors will at least double the speed of the service.

The pilot program involved 1632 FPGA servers from the pioneer of programmable chips, Altera. After the successful completion of the program, Microsoft decided in early 2015 to equip existing Microsoft data centers with such servers. These servers will initially serve Bing, and then - probably - other Microsoft services.

Each server was equipped with an Intel Xeon CPU based on a standard architecture (x86) and a board with an FPGA chip. The FPGA-chip boards in all 1632 servers were combined into a Catapult "machine search network" that handled requests from the Bing site, taking over this function from the CPUs. At the same time, the network had the ability to combine 8 FPGA boards into one node to improve performance.
