The song has been briefly covered by Breaking Benjamin in 2004 and 2005.


  1. closure

    In mathematics, closure refers to a property of some operations or functions by which the output or result always lies within the same set as the inputs. It describes the characteristic that an operation always returns a value that is also a member of the set the operation was performed on. In other words, a set is closed under an operation if the performance of that operation on members of the set always produces a member of the same set.

  6. Etymology: [Of. closure, L. clausura, fr. clauedere to shut. See Close, v. t.]


  1. Closure

    A set has closure under an operation if performance of that operation on members of the set always produces a member of the same set. For example, the real numbers are closed under subtraction, but the natural numbers are not: 3 and 8 are both natural numbers, but the result of 3 − 8 is not a natural number. Another example is the set containing only the number zero, which is a closed set under multiplication. Similarly, a set is said to be closed under a collection of operations if it is closed under each of the operations individually. A set that is closed under an operation or collection of operations is said to satisfy a closure property. Often a closure property is introduced as an axiom, which is then usually called the axiom of closure. Note that modern set-theoretic definitions usually define operations as maps between sets, so adding closure to a structure as an axiom is superfluous; however in practice operations are often defined initially on a superset of the set in question and a closure proof is required to establish that the operation applied to pairs from that set only produces members of that set. For example, the set of even integers is closed under addition, but the set of odd integers is not.
