Among his most well-known achievements in the area of computer science was the introduction of Reverse Polish Notation and the use in 1957 of a push-down pop-up stack. This preceded the work of Friedrich Ludwig Bauer and Klaus Samelson on use of a push-pop stack. The stack had been invented by Alan Turing in 1946 when he introduced such a stack in his design of the ACE computer. In philosophy, Hamblin is known for his book Fallacies, a standard work in the area of the false conclusions in logic. In formal semantics, Hamblin is known for his computational model of discourse as well as Hamblin semantics (or alternative semantics), an approach to the semantics of questions.
