Charles Babbage, an English mathematician and IT pioneer, designed an analytical machine that operated on a principle similar to that of digital computers. The machine was able to remember the basic mathematical operations. The implementation of the activities was to be carried out on pre-punched cards. Unfortunately, due to the then low technical level, the project was not implemented. In 1991, at the ScienceMuseum in London, according to the original plan, a fragment (arithmometer) of the Second Differential Machine was made, and the machine’s efficiency and correctness were proved.
