What kind of insect is actually a dragonfly from Krylov's fable?

In Krylov's fable "The Dragonfly and the Ant" there are lines: "The Jumping Dragonfly sang the red summer." However, the dragonfly is known to make no sound. The fact is that at that time the word "dragonfly" served as a generalized name for several species of insects. The real hero of the fable, as narrated by Aesop, and later by Lafontaine, is the cicada, which Krylov adapted into a dragonfly.

What is the difference between an underground spring and an artesian well?

People living in the city do not have to go to a spring or a well for water. She enters the apartment through the plumbing. However, in rural areas, far from large settlements, the situation may be quite different. A spring is a spring, which is a natural opening in the surface of the earth.

During rain, part of the water, under the influence of gravity, seeps into the soil and the rocky layer below it through small cracks and pores as deep as possible. At various depths, under the soil layer lies the lower layer of soil, in which all the cracks and holes between the stones are filled with water. The upper part of this layer is called the water table.

In valleys or other lowlands, where the soil is below the groundwater level, springs make their way through the cracks between the stones. In other words, the water accumulated in the soil seeps to the surface of the earth. Some springs do not dry up all year round, as water comes to them from the lower layers of the soil. Others operate only during the rainy seasons when the water table is at its highest.

An artesian well is also a natural source of water, but the hole for its release to the surface in this case was created not by nature, but by man. In places where a layer of gravel or sand is between dense rocky layers of soil, water accumulates in the middle loose layer.

If the terrain has a certain slope, then the water fills this layer to the top, and having no outlet to the surface, creates a lot of pressure. If you drill a well in this place, then the water, under the pressure of its entire mass, will begin to spurt with a fountain - this is an artesian well.

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Implanted brain stimulator 30.04.2024

In recent years, scientific research in the field of neurotechnology has made enormous progress, opening new horizons for the treatment of various psychiatric and neurological disorders. One of the significant achievements was the creation of the smallest implanted brain stimulator, presented by a laboratory at Rice University. Called Digitally Programmable Over-brain Therapeutic (DOT), this innovative device promises to revolutionize treatments by providing more autonomy and accessibility to patients. The implant, developed in collaboration with Motif Neurotech and clinicians, introduces an innovative approach to brain stimulation. It is powered through an external transmitter using magnetoelectric power transfer, eliminating the need for wires and large batteries typical of existing technologies. This makes the procedure less invasive and provides more opportunities to improve patients' quality of life. In addition to its use in treatment, resist ... >>

The perception of time depends on what one is looking at 29.04.2024

Research in the field of the psychology of time continues to surprise us with its results. Recent discoveries by scientists from George Mason University (USA) turned out to be quite remarkable: they discovered that what we look at can greatly influence our sense of time. During the experiment, 52 participants took a series of tests, estimating the duration of viewing various images. The results were surprising: the size and detail of the images had a significant impact on the perception of time. Larger, less cluttered scenes created the illusion of time slowing down, while smaller, busier images gave the feeling of time speeding up. Researchers suggest that visual clutter or detail overload can make it difficult to perceive the world around us, which in turn can lead to faster perception of time. Thus, it was shown that our perception of time is closely related to what we look at. Larger and smaller ... >>

Voice chat on Facebook 20.10.2009

In the near future, users of the social network Facebook will be able to communicate with each other by voice, not only through the site, but also with the help of third-party applications, since the API for implementing communications of this kind will be open.

This technology is not developed by Facebook. Vivox software, which is already successfully used in the virtual game worlds of Second Life and EVE Online, will be used for negotiating.
