Charles Babbage designs a calculator. The concept of this machine was that it should be operated by punched cards (see Jacquard 1801) and the results printed on paper. To print the results was something revolutionary in this time. Babbage thinks however that the technology at that day will not be sophisticated enough (precision of tooling etc.) to have him realize such a machine. A small scale model however is shown at a meeting of the Society.
(tolerances), financial (subsidies) and differences of opinion with his
chief engineer - Joseph Clement a tool engineer and draftsman, a
rare combination in these days - are causing the project to be shelved
in 1833. But the concept of the machine is of course extremely advanced
and probably too far out of most peoples league for this days to
even think about. Or let alone conceptualize.
