The Electric Economy Section of the "Nikola Testa" Institute of the Serb-
ian Academy of Science (OdelJenJe za elektroprivredu, Institut Srpske akad-
emiJe nauka "Nikola Tesla") has bullt an electronic differential analyzer
(elektroneki diferenci,jalni analizator). Complex equations xhich ordinarily
require days and weeks of work can be solved in fractions of a second by the
machine, and ordinary arithmetic problems are solved within millionths of a
second. Solutions are received on an opaque glass in?the form of curves.
The internal apparatus is similar to the interiors of 20 radio sets wired to-
gether. The machine has about 200 radio tubes, and is 5 meters long and 2
meters high:
