Mechanical calculator

A mechanical calculator, or calculating machine, was a mechanical device used to perform automatically the basic operations of arithmetic. Most mechanical calculators were comparable in size to small desktop computers and have been rendered obsolete by the advent of the electronic calculator. Surviving notes from Wilhelm Schickard in 1623 report that he designed and had built the earliest of the modern attempts at mechanising calculation. His machine was designed for multiplication and division and had an innovative mechanical adding machine built into the base. The surviving notes do not make it clear whether Schickard's machine would have worked as well as he reported to Kepler and might well have jammed when a number of counters were forced to move simultaneously. Two decades later in 1642 Blaise Pascal decisively solved this particular problem with his independent invention of a mechanical calculator. The comparative roles and significance of Pascal and Schickard's important inventions is discussed in much greater detail in Schickard versus Pascal: An Empty Debate?
