 Cold War


The consolidation of the cold war

The United States and the Soviet Union ended World War II as allies. Their joint action against the Axis was decisive in ridding Europe of the Nazi presence.

The clearest reason for the breakup was ideological. Capitalism and socialism, incompatible in their way of understanding different spheres of human life, from the role of the State to the priority rights of citizens, led to disagreement between the United States and the Soviet Union regarding the purposes of the political order and the methods of acting within it. Without constituting a homogeneous period, due to the aggravation of tensions followed by the distension between the rival poles, the Cold War lasted almost half a century, until the breakup of the Soviet Union, in 1991.

With the aim of fighting communism and Soviet influence, Secretary of State George Marshall launched the Marshall Plan, an investment and economic recovery program for European countries in crisis after the war. This offer extended to the countries of Eastern Europe, which had been liberated from Nazism by the Red Army. In all of them, the respective communist associations had taken power.

Understanding the Marshall Plan as an attempt to reduce its sphere of influence, the Soviet Union created the Kominform, an organism in charge of coordinating the action of European communist parties. It was also his task to remove the countries that were under its influence from North American supremacy, generating the "iron curtain" bloc (an expression used by Churchill). Complementing the Soviet reaction, in 1949 the Comecon was created, a replica of the Marshall Plan for socialist countries, aimed at their economic-financial integration.

In August 1961, the Berlin Wall was built, which concretely separated the two sides of the city and became a symbol of German division and the Cold War.


Other significant facts added to this growing international tension. One of them was the creation, in April 1949, of the North Atlantic Treaty Organization (NATO), a political-military alliance of Western countries, opposing all of Western Europe to the Soviet Union. On the Soviet side, configuring the alignment with the communist bloc, the Warsaw Pact was created in 1955. The world bipolarization reached its fullness.

In the midst of this tense situation, the Chinese Revolution and the explosion of the first Soviet atomic bomb took place in 1949. The following year, the Korean War began, one of the heights of the Cold War and until then the most serious threat to world peace after World War II.

Fungi

Fungi With bacteria, they are important decomposers, as they feed on organic substances from dead leaves, corpses and waste, contributing to the recycling of matter. Although many species of fungi are parasites of plants and animals, others maintain ecological relationships of the mutualism type, that is, relationships in which there is an exchange of benefits between different species. General features Fungi are eukaryotes and, although there are unicellular forms, such as yeast, most are formed by a tangle of filaments, the hyphae, whose set is called mycelium. The cell wall is formed by chitin, a nitrogenous polysaccharide that also appears in the skeleton of arthropods; in some cases, there is also cellulose. Some fungi also have reproductive structures, the fruiting or fruiting bodies, which correspond to the visible part above the ground, called the mushroom. Nutrition and breathing Nutrition is heterotrophic by absorbing simple organic molecules, which may come from extracorpore...

Uniform rectilinear motion

Uniform rectilinear motion The movement is relative The movement of a body, seen by an observer, depends on the reference frame in which the observer is situated.

For observer A, observer B is in motion, along with the train. However, from the point of view of observer B, observer A is moving in the opposite direction to the movement of the train on Earth. Uniform rectilinear motion Distance, speed and time When a body moves with constant velocity along a rectilinear path, we say that its motion is uniform rectilinear. The word "uniform" indicates that the velocity value remains constant. We can find the distance traveled by an ...

The set of all points whose distance from O is less than or equal to r is called a sphere with center O and radius r. The spherical surface with center O and radius r is the set of points whose distance from point O is equal to r. We can imagine a spherical surface as the "shell" of a sphere, but a shell without thickness.
