The old slide rule of my father, seen from close :)
A slide rule is a hand-operated mechanical calculator consisting of slidable rulers for evaluating mathematical operations such as multiplication, division, exponents, roots, logarithms, and trigonometry. It is one of the simplest analog computers. Invented in 1632 by William Oughtred, inspired by Edmund Gunter's logarithmic ruler. It was widely used by engineers until the late 1980s.
