What do the circles around the moon or around the sun mean?

The colored rings around the Moon or the Sun are called haloes by meteorologists. They arise from the reflection of light by ice crystals in high clouds.

Rings are signs of increasing air humidity and impending weather deterioration.

How did the surname of Rear Admiral Ivanov-Thirteenth appear?

In 1895, Ivanov, a graduate of the naval cadet corps, was promoted to midshipman and sent to serve on the Black Sea. At that time, naval officers with the same surnames were assigned serial numbers, and this Ivanov got number 13. In 1904, with the rank of lieutenant, he was appointed watch officer on the cruiser Rurik, which sank in an unequal battle during the Russo-Japanese war. During the battle, the captain of the cruiser was killed, and the officers who replaced him were also killed or injured, until the turn came to Ivanov, who gave the order to flood the ship and was the last to leave the side. For his valor, the emperor awarded the officer with the Order of St. George IV degree, and also ordered to change the name of Konstantin Petrovich to "Ivanov-Thirteenth".

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 ... >>

Mountains and deserts of Mars 05.08.2004

In January 2004, two American mobile vehicles, Spirit and Opportunity, landed on Mars.

Mars rovers that have landed on different sides of the planet are quite briskly driving around the red desert and transmitting photographs of Martian landscapes and scientific data on the composition of the soil and atmosphere to Earth. Mars rovers are equipped with infrared spectrometers, which determine the mineral composition of soil and rocks.

The European Space Agency's (ESA) Mars Express research vehicle, launched from Baikonur, went into orbit around Mars and is transmitting spectacular landscape images, but its Beagle 2 lander went missing while trying to land on Mars.
