building .industrial bunker

Typical industrial bunkers include mining sites, food storage areas, dumps for materials, data storage, and sometimes living quarters. They were built mainly by nations like Germany during World War II to protect important industries from aerial bombardment. Industrial bunkers are also built for control rooms of dangerous activities, e.g. tests of rocket engines or explosive experiments. They are also built in order to perform dangerous experiments in them or to store radioactive or explosive goods. Such bunkers also exist on non-military facilities.

building .infinity

Infinity (symbolically represented with ∞) comes from the Latin infinitas or “unboundedness.” It refers to several distinct concepts (usually linked to the idea of “without end”) which arise in philosophy, mathematics, and theology.

In mathematics, “infinity” is often used in contexts where it is treated as if it were a number (i.e., it counts or measures things: “an infinite number of terms”) but it is a different type of “number” from the real numbers. Infinity is related to limits, aleph numbers, classes in set theory, Dedekind-infinite sets, large cardinals,[1] Russell’s paradox, non-standard arithmetic, hyperreal numbers, projective geometry, extended real numbers and the absolute Infinite.
