Computer ethics the 1940s with MIT professor Norbert Wiener, the American mathematician and philosopher. While working on anti-aircraft artillery during World War II, Wiener and his fellow engineers developed a system of communication between the part of a cannon that tracked a warplane, the part that performed calculations to estimate a trajectory, and the part responsible for firing. Wiener termed the science of such information feedback systems "cybernetics," and he discussed this new field with its related ethical concerns in his 1948 book, "Cybernetics". In 1950, Wiener's second book, "The Human Use of Human Beings", delved deeper into the ethical issues surrounding
Wiener–Lévy theorem Wiener–Lévy theorem Wiener–Lévy theorem is a theorem in Fourier analysis, which states that a function of an absolutely convergent Fourier series has an absolutely convergent Fourier series under some conditions. The theorem was named after Norbert Wiener and Paul Lévy. Norbert Wiener first proved Wiener's 1/"f" theorem, see Wiener's theorem. It states that if has absolutely convergent Fourier series and is never zero, then its inverse also has an absolutely convergent Fourier series. Paul Levy generalized Wiener's result, showing that Let formula_1 be a absolutely convergent Fourier series with The values of formula_3 lie on a curve formula_4, and formula_5
