In
mathematics, a
set is called
finite if the number of its elements can be described by a
natural number. For instance, the set of
integers between -15 and 3 is finite, since it has 17 elements. The set of all
prime numbers is not finite. Sets that are not finite are called
infinite.
In physics, the term finite is in addition used in the meaning of "non-zero", for instance in a sentence like "if the distance of the two objects is finite...".
