Se ut som Känslan av kraft från Isaac Asimov. Jag läste den i korthistoriesamlingen Nine Tomorrows .
In the distant future, humans live in a computer-aided society and have forgotten the fundamentals of mathematics, including even the rudimentary skill of counting.
The Terrestrial Federation is at war with Deneb, and the war is conducted by long-range weapons controlled by computers which are expensive and hard to replace. Myron Aub, a low grade Technician, discovers how to reverse-engineer the principles of pencil-and-paper arithmetic from computers — a development which is later dubbed "Graphitics". The discovery is appropriated by the military establishment, who use it to re-invent their understanding of mathematics. They also plan to replace their computer-operated ships with lower cost, more expendable (in their opinion) manned ships to continue the war.
