The problem of soil deflation in Africa, Europe, Asia, America is very relevant. This is one of the key difficulties associated with the ecological state of the soils of our planet. Ecologists and geologists urge to pay special attention to it, arguing that underestimation of this disaster can result in a global crisis. Indeed, deflation is a serious threat to the future of the globe. Last modified: 2025-01-23 12:01

System analysis is a scientific method of cognition, which is a sequence of actions to establish structural relationships between variables or constant elements of the system under study. Relies on a set of general scientific, experimental, natural science, statistical, mathematical methods. Last modified: 2025-01-23 12:01

The question of how many dimensions there are in the Universe, as it is known for certain, people asked back in the 17th century. And if, until recently, a person only guessed that other stars have planets, and then discovered this, now it has become clear that there are much more than four dimensions.

The relational data model is a unique approach to managing parameters using structure and language according to single-order predicate logic. It was first described in 1969 by the English scientist Codd. In this project, all parameters are presented as tuples grouped into certain relationships. Last modified: 2025-01-23 12:01

The blue whale, the largest living animal, makes a sound that is much louder than the noise of a launching rocket. Such a loudness a person cannot bear. There is even a noise weapon, its volume is only a little more than the voice of a whale. What determines the sound volume? Why can intense, low sounds hurt and even be deadly, while high ones can't? Why are low sounds heard at a greater distance than high ones? The article will answer these questions. Last modified: 2025-01-23 12:01

Supramolecular chemistry is a field of science that goes beyond particles that focuses on scientific systems made up of a discrete number of assembled subunits or components. The forces responsible for spatial organization can range from weak (electrostatic or hydrogen bonds) to strong (covalent tangencies). Last modified: 2025-01-23 12:01

In Latin, the word "impulse" means a blow, a push. Man has always been surprised by the effect produced by a blow. Let's try to analyze from the standpoint of physics such concepts as impact force, momentum of force and the formula for its calculation. Last modified: 2025-01-23 12:01

The shape of a human face and its features can tell a lot about the personality of its owner. Indeed, lines or wrinkles that form over time as a result of certain repetitive facial expressions say a lot about character. This article will provide information about the shape of the eyebrows in physiognomy. And also it will be possible to learn how to recognize in people benevolence, anger, reliability and other character traits. Last modified: 2025-01-23 12:01

Atomic emission spectroscopy (spectrometry) - AES or atomic emission spectral analysis - a set of elemental analysis methods based on the study of the emission spectra of free atoms and ions in the gas phase (see the group of methods of optical spectroscopy). Usually, emission spectra are recorded in the most convenient optical wavelength range from ~200 to ~1000 nm. Last modified: 2025-01-23 12:01

At present, astronomy has adopted the division of the entire celestial sphere into 88 sections - constellations - with officially fixed boundaries. However, in the past, constellations were interpreted as sets of stars that stand out in the sky. At different times, they were given names associated with important concepts for people. The small southern constellation Compass is one of these kind of "monuments of the era". Last modified: 2025-01-23 12:01

Acceleration and speed are two important kinematic characteristics of any type of movement. Knowing the dependence of these quantities on time allows you to calculate the path traveled by the body. This article contains the answer to the question of how to find the acceleration, knowing the speed and time. Last modified: 2025-01-23 12:01

Questions of dependence (or independence) of some quantities from others can confuse the idea of physical processes to the point of complete misunderstanding. It is clear that if you heat the thermometer, then it will not get warmer outside. And what about electricity? It's not all that clear. Last modified: 2025-01-23 12:01

Movement is one of the main features of the world we live in. It is known from physics that all bodies and the particles of which they are composed are constantly moving in space even at absolute zero temperatures. In this article, we consider the definition of acceleration as an important kinematic characteristic of mechanical motion in physics. Last modified: 2025-01-23 12:01

Each company that manufactures products or provides services regularly calculates the cost of manufactured products and the cost of services. This indicator makes it clear how efficient and economical the company's production is. In addition, the cost directly affects the price level of the company. Now we will talk in detail about this company performance indicator. Last modified: 2025-01-23 12:01

In our galaxy, and indeed in the entire universe, there is a great variety of different celestial objects. In the night sky, we can observe them in the form of a huge number of twinkling dots and specks surrounding us from all sides.

From time immemorial, people have watched the night sky and noticed that in addition to stationary objects, there are those that change their position relative to the rest. Usually we say that these are stars, but is it really? What celestial bodies are called planets and what criteria must an object have in order for it to be called a planet? Which of them are part of the solar system?. Last modified: 2025-01-23 12:01

The Gauss method frightens many with its belonging to such a branch of mathematics as linear algebra, which is studied in universities and is quite complicated in itself. However, there is nothing wrong with this: the Gaussian method is just an algorithm that is enough to remember, so that later it can be applied practically without changes in any similar problems. This article will provide the basic and necessary concepts, as well as a detailed explanation on a specific example. Last modified: 2025-01-23 12:01

The information that codes for all the proteins in the body is written in the cell's DNA. Only 4 types of nucleic bases - and countless combinations of amino acids. Nature made sure that each failure was not critical and made the genetic code redundant. But sometimes the distortion still creeps in. It's called mutation. This is a violation in the recording of the DNA code. Last modified: 2025-01-23 12:01

A reflecting telescope (also called a reflector) is a telescope that uses a single set or combination of curved mirrors to reflect light and create an image. The reflecting telescope was invented in the 17th century by Isaac Newton as an alternative to the refracting telescope, which at the time was a design suffering from severe chromatic aberration.
