John W. Campbell because of lack of credits for French and trigonometry. He also attended, without graduating, the Massachusetts Institute of Technology (MIT), where he was befriended by the mathematician Norbert Wiener (who coined the term "cybernetics") – but he failed German and MIT dismissed him. After one year at Duke University, he graduated with a Bachelor of Science in physics in 1932. Campbell began writing science fiction at age 18 while attending MIT and sold his first stories quickly. From January 1930 to June 1931, "Amazing Stories" published six of his short stories, one novel, and six letters. Campbell was editor of
Wiener–Hopf method is analytic in the upper half-plane, analytic continuation guarantees existence of an entire function which coincides with the left- or right-hand sides in their respective half-planes. Furthermore, since it can be shown that the functions on either side of the above equation decay at large , an application of Liouville's theorem shows that this entire function is identically zero, therefore and so Wiener–Hopf method The Wiener–Hopf method is a mathematical technique widely used in applied mathematics. It was initially developed by Norbert Wiener and Eberhard Hopf as a method to solve systems of integral equations, but has found wider use
