What is the deepest ocean?

The oceans remain a mystery to us in many ways. We don't even know the age of the oceans. It is quite possible that oceans did not exist in the early stages of the Earth's development.

Today, man explores the ocean floor in order to better study them. Up to a depth of 3600 m, the bottom of the oceans is covered with soft silty sediments. They consist of calcareous skeletons of the smallest marine animals. At depths exceeding 6 km, the bottom is covered with fine reddish silt, called "red clay". It consists of particles of animal skeletons, the remains of small plants and volcanic ash.

Currently, the depth of the oceans is measured by sending sound waves into the depths and receiving the reflected signal. To do this, measure the time during which the sound wave reaches the bottom and returns after reflection; after that, the time value is divided in half.

Based on these measurements, we have a pretty good idea of the average depth of the various oceans, as well as their deepest points. The deepest is the Pacific Ocean, its average depth is 4281 m. Next comes the Indian Ocean with an average depth of 3963 m. Then comes the Atlantic Ocean with an average depth of 3926 m. For comparison: the Baltic Sea has an average depth of only 55 m!

To date, the deepest place in the oceans is known - in the region of the Guam Islands - 10 m. Another deepest place is located in the Atlantic Ocean near the Guam Islands - here the depth reaches 790 m. 9219 m

What is an operetta?

As an independent genre, operetta arose relatively recently, in the middle of the XNUMXth century in France. And before that, an operetta (translated from Italian "operetta" means "small opera") was called a small comic opera.

The operetta has everything: song verses, dances, conversational dialogues. And the operatic forms in the operetta - the aria, the vocal ensemble, the choir and the ballet scenes - have a lighter character.

Compared with opera, there are also new musical forms in operetta: couplets - songs almost always performed at a fast pace and recitative, as well as cancan - a fast dance, which often becomes the culmination of a performance. Great attention in operettas is paid, of course, to the text, which should be witty, cheerful, playful and very bright. Operetta artists must certainly have a good singing voice, acting skills and excellent diction.

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 ... >>

Drone - helium balloon 20.11.2021

Despite the ease of use, multicopter drones make quite a lot of noise during operation, consume a lot of energy, and besides, they are potentially dangerous due to rotating blades. An alternative was presented by the Japanese company NTT Docomo, releasing a balloon-like drone that moves extremely quietly.

Classic drones with spinning blades pose some threat to humans, animals, and even other drones. Many of them use sensors and sophisticated algorithms for avoiding obstacles, some manufacturers create special casings to protect against the consequences of collisions and other solutions to maintain functionality even after an incident.

Docomo's idea is much simpler - get rid of the blades completely. The new drone is essentially a balloon filled with helium. The bottom-mounted camera allows you to take photos and videos, and the drone also has a multi-colored LED backlight that can be turned on as needed.

The main advantage of the novelty is that it practically does not make sounds in flight. In addition, there is no need to constantly maintain the device in the air due to the use of an inflatable ball in the design, which ensures a long time of autonomous flight.

An exclusive component of the Docomo drone is its propulsion system. Miniature ultrasonic modules are mounted on a lightweight frame, generating microvibrations in the air - they allow the drone to move in any direction.

Balloon drones have been around for quite some time, but some still use propellers and others are balloon-kite hybrids designed to operate at high altitudes. Docomo says its solution is perfect for use during any kind of event, indoors or outdoors (we can assume that the weather for this should be close to ideally calm).
