The Neper Bones

“…there is nothing … so troublesome to mathematical practice ...than the multiplications, divisions, square and cubical extractions of great numbers, which besides the tedious expense of time are for the most part subject to many slippery errors, I began therefore to consider … by what certain and ready art I might remove those hindrances”

— John Napier

Description

In 1614, Edinburgh-born John Napier invented logarithms. A means of simplifying complex calculations, they remain one of the most important advances in the study and practical application of mathematics. Napier’s ‘bones’ or ‘rods’ are just one of the methods this brilliant mathematician invented to speed up arithmetic. These could be assembled in different ways to multiply or divide large numbers by reading across the columns of figures.
