What is an exchange?

The exchange is a regular wholesale market for goods sold by design (commodity exchange), securities (stock exchange), foreign exchange (currency exchange) and labor (labor exchange). But usually only the stock and currency exchanges are understood by this word.

The world's first stock exchange was opened in 1409 in the Dutch city of Bruges. The name supposedly comes from the Van der Burze trading dynasty. The first shares in the modern sense of the word were the securities of the Dutch East India Company, which were sold and bought in 1602 on the Amsterdam Stock Exchange.

Which plane is the fastest?

Currently, the American Lockheed SR-71A reconnaissance aircraft remains the fastest aircraft, although it is far from new. On July 28, 1976, it managed to develop a record speed - 3529 kilometers per hour. At such high speeds, the aircraft heats up to 400 °C. Pilots cannot fly it without a special space suit.

The same aircraft was used for the fastest flight across the Atlantic. The Lockheed SR-5570A covered a distance of 71 kilometers from New York to London in just 1 hour and 54 minutes. The unofficial English name for this aircraft means "Blackbird". The fastest aircraft in the world received this nickname for its dark color.

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 ... >>

Global warming has shifted the earth's axis 29.04.2021

Research by the Institute of Geographical Sciences and Natural Resources Research has shown that the massive melting of glaciers as a result of global warming has provoked noticeable shifts in the Earth's axis of rotation. This process began around the 1990s. The problem of climate change, which has been provoked by human activity, clearly demonstrates the destructive impact of people on the planet.

The geographic north and south poles of a planet are the points where its axis of rotation intersects the surface, but they are not fixed. Changes in the distribution of the Earth's mass cause the axis, and hence the poles, to move.

In the past, only natural factors such as ocean currents, for example, have contributed to the repositioning of the poles. But new research shows that since the 1990s, the loss of hundreds of billions of tons of ice a year as a result of the climate crisis has sent the poles moving in new directions.

Scientists have found that the direction of the movement of the poles shifted from south to east in 1995, and the average speed of movement from 1995 to 2020 was 17 times higher than from 1981 to 1995. Since 1980, the position of the poles has shifted by about 4 meters.

The largest factor in the displacement of the earth's axis was precisely the melting of glaciers and the "pumping of groundwater." Groundwater is stored underground, but once pumped for drinking or agricultural use, most of it flows into the sea, redistributing its weight around the world.

The scale of this influence means that it is necessary to declare a new geological epoch - the Anthropocene, scientists say. Since the middle of the 20th century, there has been a marked acceleration in carbon dioxide emissions and sea level rise, the destruction of wildlife, and the transformation of land through farming, deforestation, and construction.
