Science

Society is an incredibly interesting subject to study, as understanding the features of its functioning helps ordinary people significantly improve their lives and influence the world in a positive way. To begin to study society, it is necessary to understand what sciences study society. And in order to get an answer to this question, it is necessary to turn to such a complex of sciences as social science, which includes at least six main scientific disciplines.

This article will consider the phenomenon of modification from the point of view of different spheres of human life and activity, and will also give examples of the manifestation of this concept in science and everyday life. So, modification is a change in some object with the parallel acquisition of new functions or. Last modified: 2025-01-23 12:01

Irritability is the ability of an organism or individual tissues to respond to the environment, it is also the ability of a muscle to contract in response to stretching. Excitability is a property of a cell that allows it to respond to irritation or stimulation, for example, the ability of nerve or muscle cells to respond to an electrical stimulus.

Synchrotron radiation is electromagnetic radiation that occurs when charged particles are accelerated radially, that is, when they are subjected to an acceleration perpendicular to their velocity (a ⊥ v). It is produced, for example, in synchrotrons using bending magnets, undulators and/or wigglers. Last modified: 2025-01-23 12:01

Great interest for modern astrophysics and cosmology is a special class of phenomena called gamma-ray bursts. For several decades, and especially actively in recent years, science has been accumulating observational data regarding this large-scale cosmic phenomenon. Its nature has not yet been fully elucidated, but there are sufficiently substantiated theoretical models that claim to explain it. Last modified: 2025-06-01 07:06

The design resistance of wood is an important indicator in the design of wooden structures. Wood is a durable, but malleable material that will not always be able to withstand the planned loads. In order for the wood not to collapse during operation under the influence of loads and external factors, it is necessary to calculate its ability to resist external influences.

The bulk of the country's citizens (79%) are in the western federal states. The population density of Germany is distributed unevenly across the state. If in areas with developed industry (the agglomerations of the Ruhr and the Rhine) there are one thousand one hundred people per square kilometer, then in Mecklenburg-Western Pomerania there are only seventy-six citizens per km2. At the same time, Germany ranks fourth in Europe in terms of population density (231 people per km2). Last modified: 2025-01-23 12:01
