Empty set

The Empty Set (generally denoted 
or 
) is the (unique) set containing no elements. It is therefore a subset of every set.
In Set Theory, this is the only set that we know exists. All other sets must be formed using the Empty Set and a series of axioms. Thus, in a sense, the Empty Set is the basis of all mathematics as we know it - the "nothing" from which everything is formed.
