Between inventing the concept of a universal computer in 1936 and breaking the German Enigma code during World War II, Alan Turing (1912–1954), the British founder of computer science and artificial intelligence, came to Princeton University to study mathematical logic.
Some of the greatest logicians in the world—including Alonzo Church, Kurt Godel, John von Neumann, and Stephen Kleene—were at Princeton in the 1930s, and they were working on ideas that would lay the groundwork for what would become known as computer science.
This book presents a facsimile of the original typescript of Turing’s fascinating and influential 1938 Princeton PhD thesis, one of the key documents in the history of mathematics and computer science. The book also features essays by Andrew Appel and Solomon Feferman that explain the still-unfolding significance of the ideas Turing developed at Princeton.
A work of philosophy as well as mathematics, Turing’s thesis envisions a practical goal—a logical system to formalize mathematical proofs so they can be checked mechanically.
