Put away your calculators – the National Museum of Scotland in Edinburgh has announced that it will host an exhibition all about John Napier to celebrate the 400th anniversary of the publication of his treatise on logarithms, *Mirifici Logarithmorum Canonis Descriptio*.

Napier’s pioneering work on logarithms offered simple and elegant solutions to previously laborious and error-prone calculations; enabling more calculations to be completed in an hour than had previously been completed in one day. From the introduction of the decimal point to the development of slide rules and ‘Napier’s rods’, this exhibition will explore how Napier’s revolutionary innovations advanced and influenced mathematics from the 17th Century to the modern day.

*Power of Ten* will run from 28 March to 6 July, and entry is free.
