The concept of "polygon" is often used when it comes to military tests, nuclear weapons, artillery firing and so on. In the modern world, this term has a fairly wide use, and its meaning goes beyond military topics.

What is a polygon?

This word is translated from Greek as "polygon". In the most common sense of the word, a landfill is a piece of land or sea specially equipped with some kind of structure. Its territory usually has the shape of an irregular polygon, which explains its name. The landfill area can be huge - hundreds of square kilometers. Along the perimeter, it usually has special restrictions that prevent unauthorized entry. A polygon can include not only a piece of land, but also water and air space.

For the placement of landfills choose territories unsuitable for economic activity: deserts, steppes, tundras. This helps to minimize economic damage. Flights may be restricted in the airspace of the range.

Polygon classification

Polygons come in various types. By ownership, they are divided into public and private.

According to the purpose, the ranges are military, nuclear, research, testing, factory, civilian, training, garbage.

Most often, a training ground is a territory equipped by governments of countries for military purposes for conducting combat exercises, artillery tests, air flights, and bombing. Such ranges are often equipped with military camps, checkpoints, fenced with barbed wire, etc.

Weapons, military equipment, devices are being tested at the test sites.

A factory test site is a place where machinery and equipment manufactured by the manufacturer are tested.

Civilian ranges can be equipped with special areas for educational or recreational purposes, such as role-playing ranges.

Nuclear test site

The first atomic bomb tests were carried out in 1945 in Trinity, New Mexico. Since then, many countries have begun to equip territories for such tests.

A nuclear test site is an area designated for testing nuclear weapons.

Several famous but now abandoned landfills in the world:

• Totsky polygon (USSR);
• Eniwetok (Rep. Marshall Islands);
• Lop Nor Lake (China);
• Semipalatinsk test site (USSR, Kazakhstan);

• Polygon inNevada;
• Pungeri (North Korea);
• Novaya Zemlya (Russia).

Nuclear testing causes terrible harm to the environment. Radiation pollutes vast areas far beyond the landfills. Land becomes unsuitable for livestock and crop production. In addition, radioactive contamination, spreading by air, leads to radioactive fallout. Getting into the atmosphere, radioactive waste causes great harm to human he alth. Underwater tests of atomic bombs caused significant damage to the ecology of the seas.

Despite this, nuclear test sites are a popular destination for extreme tourism. People are not stopped by the radioactive threat, and they often go to former test sites to get acquainted with the history of tests and look at the craters left from the explosions.

Trash landfills

Human activity contributes to a large amount of household waste. A landfill for solid domestic waste is a facility designed for the processing and disposal of solid domestic waste. MSW usually includes plastic waste, glass, rubber, bones, wood, metals.

Most often, solid waste landfills are in the form of a pit and are located far from residential areas, in order to avoid damage to human he alth. To ensure environmental safety, landfills are located away from green spaces, water bodies and groundwater.

In Russia, the situation with landfills is unfavorable. For household waste disposala significant increase in the number of processing equipment is required. In addition, the system of proper waste separation has not yet been debugged in Russia: basically, garbage is dumped in one heap.

The biggest landfills are in:

• Chittatonge (Bangladesh);
• New York (USA);
• Agbogbloshi (Havana);
• Fresh Killze (USA);
• Puente Hills (USA).

Polygon in mathematics

The concept of a polygon is also found in the exact sciences only in a different meaning. The word "polygon" can be used to refer to a polygon in geometry. Also, the polygon can be in the form of a graph. The frequency polygon and the relative frequency polygon is a curved line connecting the points of a graph representing probability densities.

Thus, polygon is an ambiguous term used in many fields of activity. Mostly this concept is used to refer to limited places or territories equipped for various needs.
