    At the US Army Signal Security Agency during World War II, two systems were built to assist cryptanalysts in breaking messages enciphered on Enigma-type machines. Called the Autoscritcher, the first machine used relay technology. The final system, the Superscritcher, was fully electronic and contained about 3500 vacuum tubes. Both machines operated successfully. The system approach both machines w... View full abstract»

    The computing problems in the field of tidal calculations in the Netherlands between 1920 and 1960 are described. These calculations were necessary to predict the changes in the water movements caused by hydraulic works like the Zuiderzee Works and the Delta Works. The growth of computing problems in this field was caused not only by the increasing technical complexity of the hydraulic works, but ... View full abstract»

    While the career of the Charles Babbage (1791-1871) shows a remarkable range of interests, strong threads bind together several of the principal ones: algorithmic thinking, with intimate links to algebra and to semiotics. The links connect especially his mathematical researches in functional equations with his work on mathematical tables and on calculating machines, but they are evident also in so...
