Roots of mathematics 16: Napier's rods

Research output: Contribution to journalArticleProfessional

Abstract

The Scottish mathematician John Napier is best known for inventing the logarithm. However, in his attempts to facilitate multiplication, he left behind something special: the so-called calculator rods. These sticks are based on an old calculation technique called gelosia. This technique can be taught using only paper and pen, but it is even more fun to recreate the sticks with your pupils and to use them to do the maths.
