In computers, a page table is a map between the [this word] of virtual addresses and the [this word] of physical addresses. Two events are this-like if there exists some reference frame in which they are observed to occur at the same time, but not in the same (*) place. In probability, the set of all possibilities is referred to as the sample [this]. The structure of this type named after Minkowski is comprised of four dimensions. Triangles have three right angles in a non-Euclidean structure of this type. For 10 points, name this concept often paired with "time" in mathematical models of the universe.
