Hartree’s differential analyser – an electromechanical computer

Monday 13 October 2014
Hartree’s differential analyser is a purely mechanical machine built in 1935 to grind out solutions to differential equations. A part of the machine at MOSI (Manchester Museum of Science and Industry) has recently been restored to working order, and a video of it running will be shown.

Don’t know what differential equations are? Have no fear! All will be explained. In it day, this machine solved many real problems, including many related to the war effort.

Charles Lindsey retired some years ago from The University of Manchester, Department of Computer Science. He is a volunteer at the Museum of Science and Industry, and a member of the Computer Conservation Society.

Charles prepared his own handout here it is.
