  • Abstract
    In 1840, Thomas Fowler, a self-taught English mathematician and inventor, created a unique ternary calculating machine. Recently, all detail of this machine was lost. A research project begun in 1997, uncovered sufficient information to enable the recreation of a physical concept model of Fowler´s machine. The next step is to create a historically accurate replica.
