Why is Costa Rica called that?

In 1502, the Columbus expedition, which landed on an unknown shore, drew attention to the local Indians, hung with gold jewelry. Thinking that there are gold deposits here, the Spaniards called their discovery Costa Rica, which means "rich coast". Subsequently, it turned out that Costa Rica is very poor in minerals.

What happened in the life of film director Milos Forman when he came across an egg with two yolks?

In the Czech Republic, there is a tradition - when a child is born in a family, the newly-made father is served a plate of steaming lentils, where they break a raw egg. And film director Milos Forman, in his autobiography, told about an amazing case: when twins were born to him, they also arranged such a dish of lentils for him. But in the broken egg, instead of one, there were two yolks.

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 ... >>

sensitive road 02.03.2000

If carbon fibers are mixed into concrete, such a road surface will change its electrical conductivity under the influence of the weight of cars passing on it.

Deborah Chang from the University of Buffalo (USA), who discovered this effect, suggests using it to make roads sensitive to the movement of cars and even bicycles.

It will be possible to measure the weight of heavy vehicles on the move (and charge them a fare corresponding to the weight), determine the location and speed of individual vehicles, use their signals to switch traffic lights.
