Calculating in Everyday Life

Karl Kleine is a retired professor of computer science, who worked on concepts, methods and tools for software development. His second line of professional interest were reliable and trustworthy IT infrastructures. But for the last two decades his research area became the history of computing for science and engineering in the pre-computer aera, up to the 1960s and the computational devices used. His particular interest lies in instruments based on the logarithmic principle and its practical use in all forms of slide rules and disks. The subject lies in the intersection of the history of mathematics, the history of science and the history of engineering. Prof. Kleine is member of the Oughtred Society, the German RST, the British UKSRC and the Dutch KRING as well as professional computer science organizations. He is a fellow of the Oughtred Society and got the Oughtred Society Award in 2014.
