Set Theory
There are a isomorphism between Algebra of sets and the Boolean algebra, that is, they have the same structure. Then, if we map boolean operators into set operators, the "translated" above text are valid also for sets: there are many "minimal complete set of set-theory operators" that can generate any other set relations. The more popular "Minimal complete operator sets" are {¬, ∩} and {¬, ∪}.

Famous quotes containing the words set and/or theory:
“Ye ugly, creepin, blastit wonner,
Detested, shunn’d by saunt an’ sinner,
How dare ye set your fit upon her,
Sae fine a lady!”
—Robert Burns (1759–1796)
“No one thinks anything silly is suitable when they are an adolescent. Such an enormous share of their own behavior is silly that they lose all proper perspective on silliness, like a baker who is nauseated by the sight of his own eclairs. This provides another good argument for the emerging theory that the best use of cryogenics is to freeze all human beings when they are between the ages of twelve and nineteen.”
—Anna Quindlen (20th century)
