  Cantor
       
          1.  A mathematician.
       
          Cantor devised the diagonal proof of the uncountability of the
          {real numbers}:
       
          Given a function, f, from the {natural numbers} to the {real
          numbers}, consider the real number r whose binary expansion is
          given as follows: for each natural number i, r's i-th digit is
          the complement of the i-th digit of f(i).
       
          Thus, since r and f(i) differ in their i-th digits, r differs
          from any value taken by f.  Therefore, f is not {surjective}
          (there are values of its result type which it cannot return).
       
          Consequently, no function from the natural numbers to the
          reals is surjective.  A further theorem dependent on the
          {axiom of choice} turns this result into the statement that
          the reals are uncountable.
       
          This is just a special case of a diagonal proof that a
          function from a set to its {power set} cannot be surjective:
       
          Let f be a function from a set S to its power set, P(S) and
          let U = { x in S: x not in f(x) }.  Now, observe that any x in
          U is not in f(x), so U != f(x); and any x not in U is in f(x),
          so U != f(x): whence U is not in { f(x) : x in S }.  But U is
          in P(S).  Therefore, no function from a set to its power-set
          can be surjective.
       
          2.  An {object-oriented language} with fine-grained
          {concurrency}.
