 ## Background
 The paper "On Computable Numbers, with an Application to the Entscheidungsproblem" was published by Alan Turing in 1936. In this groundbreaking paper, Turing introduced the concept of a universal computing machine, now known as the Turing machine.

 ## Significance
 Turing's paper laid the foundation for the theory of computation and had a profound impact on the development of computer science. The Turing machine became a fundamental concept in theoretical computer science, serving as a theoretical model for studying the limits and capabilities of computation. Turing's work also influenced the development of programming languages, algorithms, and the design of modern computers.
