    More precisely, L/ukasiewicz invented Polish Notation.  Reverse Polish
Notation is just Polish Notation written backwards.  I first encountered
Polish notation while studying symbolic logic; certain proofs are easier
when well-formed formulas are written in Polish Notation.  The notation is
reversed when used for calculation because then it's easy to process the
formula by pushing/pulling tokens and values on/off a stack.
