When John Napier published his invention of logarithms in 1614 he
was announcing one of the greatest advances in the history of
mathematics, and log tables were used universally until the mid
1970s. With his Rabdologia, an ingenious calculating tool composed
of numbered rods which came to be known as 'Napier's Bones', he
enabled people in the marketplace to do multiplication sums without
knowing any multiplication tables. Perhaps the most extraordinary
thing about this most extrordinary man was that his great
inventions were made without the stimulus of talking to other
mathematicians in mainstream Europe. Working away in comparative
isolation in a tower house in Scotland, Napier produced methods of
calculation that literally changed lives all over the world. He is
the father of the slide-rule and the grandfather of today's
calculators. Despite his achievements, he remains curiously
uncelebrated, and this absorbing story of his life aims to give
John Napier his true status. This new edition has been redesigned
in a new format and has a new cover.
