Analytic and Difference Engines

  • Gerard O’Regan


The analytic and difference engines were designed by Charles Babbage in the nineteenth century. The difference engine was designed to produce mathematical tables for various mathematical functions, and the machine was designed to compute polynomial functions (many mathematical functions may be approximated by polynomials). The analytic engine was designed to execute all tasks expressed in algebraic notation, and it provided the vision of a modern computer.
