Pallet 1 of 12 - Part of Manchester University Differential Analyser, consisting of 16 feet central frame, 4 integrators, 2 input tables, output table, camera. The Manchester Differential Analyser is an analogue computer designed to solve a class of mathematical functions called differential equations. This machine was built by the Metropolitan-Vickers Electrical Company and completed in 1935 for the Physics Department at Manchester University. The machine was based on an American design, powered by electric motors, and uses mechanical components to model mathematical relationships. The central device is a disc-and-wheel device integrator which performs mathematical integration. Manchester University Differential Analyser Mathematics 1935
