Can dolphins talk?

Representatives of this family of marine mammals make very complex combinations of sounds. Some sounds serve as a kind of echo sounder for them: with their help, dolphins determine distances. But there are also those that serve as animals for communication, and dolphins from different flocks often do not understand each other. However, whether these sounds can be considered a full-fledged language of communication is not yet clear.

How high is the seventh heaven?

According to the International Cloud Atlas, Cloud 0, better known as cirrus, is considered the highest, white and fibrous, consisting of thin filaments or flakes. The height of a cirrus cloud can reach 12 m.

The ninth cloud is a cumulonimbus (cumulo-nimbus), a massive "tower", foreshadowing a thunderstorm. Cumulonimbus is at the very bottom of the scale, since a single cloud of this type can cover a whole range of altitudes - from several hundred meters to the very edge of the stratosphere (approximately 15 thousand meters).

As with most idiomatic phrases, "seventh heaven" or "ninth cloud" can hardly be tied to any one particular source. A cloud of seven, eight, nine - they are all officially registered, so, most likely, people simply settled on the number nine, since nine seemed to them a lucky number. Moreover, who will deny how attractive it is - to lie on a large soft cloud and enjoy life?

The International Cloud Atlas was first published in 1896, after the International Meteorological Conference established the Committee on Clouds to harmonize an international system for naming and identifying different types of clouds.

The ten categories indicated were based largely on the original ideas of Luke Howard (1772-1864), an English chemist who published an Essay on the Modification of Clouds in 1802.

A great influence on Howard's writings was his personal experience: the case of abnormal weather conditions that Luke encountered in 1783 as a child - when volcanic eruptions in Japan and Iceland led to the formation of the "Great Fog" that covered most of Europe.

Howard's work inspired such famous landscape painters as John Constable, D.M. W Turner and Caspar David Friedrich. The great Goethe dedicated four poems to Howard, calling the modest English Quaker "the godfather of the clouds."

Clouds are collections of tiny drops of water or ice crystals held in suspension in the atmosphere. All these droplets or crystals are formed due to the condensation of water vapor around even smaller particles of things we all know like smoke or salt. Scientists call them "condensation nuclei".

Cirrus are the only clouds in the sky that are made entirely of ice. In the atmosphere, they are represented much more significantly than previously thought. What's more, they help regulate the Earth's temperature. Quite often, the initiator of their formation is the contrails of jet aircraft.

When air traffic was completely blocked after the tragedy of September 11, 2001, daily temperature fluctuations in the United States increased by 3 ° C over the next forty-eight hours. The reason is the reduction of feathery protection and, as a result, the emission of more heat at night and the transmission of more sunlight during the day.

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 ... >>

LEDs for street lighting 01.12.2007

LEDs became known to the general consumer in the 70s of the last century, when the first pocket calculators and electronic wristwatches appeared on sale. Then they shone only with red light and could only be used for indication.

Now the development of these miniature light-emitting devices has reached the point that they are beginning to be used in street lamps. LEDs are economical, durable, unlike the street lamps currently used, do not contain mercury, are not afraid of shocks and do not explode.

The University of Manchester (England) and a company founded by one of his students are developing extra-bright LEDs for street lighting. They will serve for at least 10 years, after which the brightness will decrease by only 30%, which will allow you not to change the lamp for another two or three years (the human eye only detects a decrease in brightness by half).

Experimental LED lights are already on one of the streets of the German city of Regensburg.
