31Separated sets — In topology and related branches of mathematics, separated sets are pairs of subsets of a given topological space that are related to each other in a certain way.The notion of when two sets are separated or not is important both to the notion of… …
32Moore reduction procedure — In computer science, the Moore reduction procedure is a method used for DFA minimization. The concept is to start assuming that every state may be able to combine with every other state, then separate distinguishable states into separate groups… …
33Decoherence-free subspaces — A decoherence free subspace (DFS) is a subspace of a system s Hilbert space that is invariant to non unitary dynamics. Alternatively stated, they are a small section of the system Hilbert space where the system is decoupled from the environment… …
34Subjunctive mood — In grammar, the subjunctive mood (abbreviated sjv or sbjv) is a verb mood typically used in subordinate clauses to express various states of irreality such as wish, emotion, possibility, judgment, opinion, necessity, or action that has not yet… …
35Topological indistinguishability — In topology, two points of a topological space X are topologically indistinguishable if they have exactly the same neighborhoods. That is, if x and y are points in X, and A is the set of all neighborhoods which contain x, and B is the set of all… …

37Hausdorff space — In topology and related branches of mathematics, a Hausdorff space, separated space or T2 space is a topological space in which distinct points have disjoint neighbourhoods. Of the many separation axioms that can be imposed on a topological space …

39Species — In biology, a species is one of the basic units of biological classification and a taxonomic rank. A species is often defined as a group of organisms capable of interbreeding and producing fertile offspring. While in many cases this definition is …
40Rubik's Revenge — in solved state The Rubik s Revenge (also known as the Master Cube) is the 4×4×4 version of Rubik s Cube. Invented by Péter Sebestény, the Rubik s Revenge was nearly called the Sebestény Cube until a somewhat last minute decision changed the… …
