analytical analyser of harmonics

From Pasa Bon! we are acquainted with the with the 1959 breakthrough computing advancement from engineer and scientist Jacek Karpiński (*1927 – †2010) in collaboration with Janusz Tomaszewski, the transistor-powered AKAT-1.
Constructed to solve differential equations for better modelling of heat dissipation in motors and shock absorption in brakes and building off the success of an earlier prototype used to make more precise weather forecasts, Karpiński gave his latest analogue unit a space-age housing and interface that looks like something out of science-fiction. Later achievements in the industry include standardising coding language and a machine called the Perceptron that could distinguish objects by shape and was one of the pioneering examples of algorithmic learning through supervised learning. Normally the AKAT-1 can be visited at the Muzeum Techniki in Warsaw.
