Examples of conflict are found everywhere, from petty quarrels to international confrontations. The consequence of one of these confrontations - Islamic fundamentalism - is considered on the scale of one of the largest world problems, bordering on the threat of the Third World War. However, studies have shown that conflict is a fairly broad and complex concept to evaluate it unambiguously from a destructive point of view. Last modified: 2023-12-17 05:12

There are no absolute dielectrics in nature. The ordered movement of particles - carriers of electric charge - that is, current, can be caused in any medium, but this requires special conditions. We will consider here how electrical phenomena proceed in gases and how a gas can be turned from a very good dielectric into a very good conductor. Last modified: 2023-12-17 05:12
Evolutionary doctrine is the sum of all ideas about the patterns, mechanisms of changes occurring in organic nature. According to him, all currently existing species of organisms originated from their distant "relatives" through a long change. It analyzes how individual organisms develop (ontogeny), considers the development paths of integral groups of organisms (phylogeny) and their adaptation. Last modified: 2023-12-17 05:12
The Earth's atmosphere is a complex, dynamic system, therefore, to improve the accuracy of forecasting, it is necessary to take into account its state in different regions at every moment.

Ancient alchemists dreamed of transmuting base metals into noble ones. Not only base metals in gold; but the abundant creation of elements that rewrite the book of genesis. Modern science has proved the impossibility of this phenomenon, but the mystical aspirations of alchemists can still be realized in games like Thaumcraft, a popular Minecraft mod.

At the moment, science knows one hundred and five chemical elements, systematized in the form of a periodic table. The vast majority of them are classified as metals, which implies that these elements have special qualities. These are the so-called metallic properties. Such characteristics, first of all, include plasticity, increased thermal and electrical conductivity, the ability to form alloys, and a low value of the ionization potential.

Signs that are useful for humans are not always needed and important for animals. Nature is also able to preserve some species, and eliminate some. This process is called natural selection, and interspecies struggle is one of the tools of this process. That is, animals compete with each other for food, water, territory, and so on. This is how species evolve, they are forced to adapt to some factor or simply disappear from the face of the Earth. Last modified: 2023-12-17 05:12

In short, Pierre Simon Laplace is a scientist known in the scientific world as a mathematician, physicist and astronomer of the 19th century. He made a decisive contribution to the theory of planetary motion. But best of all, Laplace is remembered as one of the greatest scientists of all time and is called the "French Newton". In his writings, he applied Isaac Newton's theory of gravity to the entire solar system. His work on the theory of probability and statistics is considered groundbreaking and influenced a whole new generation of mathematicians. Last modified: 2023-12-17 05:12
From time immemorial, mankind has tried to logically explain various electrical phenomena, examples of which they observed in nature.
