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 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 in solving two-dimensional partial differential equations with mixed boundary conditions on the same boundary. In general, the method works by exploiting the complex-analytical properties of transformed functions. Typically, the standard Fourier transform is used, but examples exist using other transforms, such as the Mellin transform. In general, the governing equations and boundary conditions are transformed and these transforms are used to define
