How is baseball played?

This game was born in the USA, and then spread to other countries. She looks like a Russian lapta.

Two teams of 9 people play on a square field with a side measuring 27,45 m. In one corner is the so-called home, or own, base, the rest are counterclockwise, respectively, the first, second and third bases. In the middle of the field there is a thrower (pitcher), to whom the opponent's batter standing on "his base" serves the ball. He hits the ball with a wooden stick, and then runs from base to base, accompanied by the players of his team who were standing on the base. Each batter who was able to run across the entire field from base to base receives one point (home run).

What do molluscs eat?

Do you like eating shellfish? For a lot of people, the mere thought of it can ruin their appetite. This has probably been the case for thousands of years. No one in Europe even thought that you can eat this creature, until the white man came to America and saw that the Indians were doing it! Mollusks have a soft body without bones, protected by two hard shells tightly closed, like the binding of a book.

There are two main types of mollusks: elongated, or soft shell, mollusks and round, or hard shell.

Soft shells live in ocean silt, occupying a peculiar position. They "stand" in the mud at one end, like a book on a bookshelf. Their upper end is sharper. When the shell is opened, a long process comes out of it, which people call the "neck". This process squeezes out water when something causes the mollusk to retract its neck and close the valves.

Hard-shelled more soft-shelled, they lie on the bottom of the ocean near the shore, slightly buried in sand or silt. Very young hard-shelled, eaten, are called "short-necked" molluscs. Those that are not so small are sometimes called "cherry pits".

What do clams eat? They feed on marine microorganisms, which they absorb through their necks. Mollusks are also able to move: between the free edges of the two valves they have a leg, with which they burrow into the silt or move along the ocean floor. The largest of the mollusks, the giant clam, has a shell weighing 180-225 kilograms. It lives on the coral reefs of India.

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 ... >>

latex gold 19.01.2020

Swiss scientists have managed to develop a form of gold that weighs 5-10 times less than usual. The density of the new metal is 1,7 g/cm3, while that of classical gold is about 15 g/cm3.

Researchers have obtained ultralight metal from protein fibers, polymer latex and gold nanocrystals. First, scientists developed a special mixture and created a dispersion that turns salts into a gel. Then the water in it was replaced with alcohol and the gel was placed in a chamber where the alcohol was mixed with carbon dioxide.

As a result of the experiment, a homogeneous airgel was formed, which was compacted under the influence of heat to the desired shape. Gold has retained the 18 carat composition (750 fineness).

The new material is similar to glass plastic but lighter than aluminum and is suitable for use in watches, jewelry, radiation protection, catalysis and electronics.
