He believed that this would occur either between 1688 or 1700. Following this work’s publication, Napier seems to have occupied himself with the invention of secret instruments of war, for in a manuscript collection now at Lambeth Palace, London. He explained his device in his book Rabdologiae; seu Numerationes per Virgulas libri duo (based on two volumes) in 1617. Napier studied at St Salvator's College, St Andrews. This rule was used at Dounreay nuclear power station. He also made significant contributions to spherical trigonometry, particularly by reducing the number of equations used to express trigonometrical relationships from 10 to 2 general statements. These let people use logarithms without the number tables. Finally, a hands-on experience will almost certainly surprise the students while also sharing another aspect of Napier’s life. By 1630 the first slide rules had been constructed by arranging two of Gunter’s scales so that they could move side by side. His interests and expertise ranged from philosophy, religion and politics, to astronomy, military invention and agricultural improvement, but it is for his mathematical work which he is primarily remembered. Napier's bones is a manually-operated calculating device created by John Napier of Merchiston, Scotland, to calculate products and quotients of numbers. Babbage’s ‘difference engine’ was intended to solve these problems, by calculating the numbers and producing printing plates automatically. This is a collection of rods that can easily be arranged to aid in multiplying large numbers. His family had owned the Merchiston estate from the 1430 s when one of his ancestors acquired the estate, becoming the first Napare of Merchiston. However, things were about to improve.

Napier worked out a correspondence between two series, and filled in the gaps between the numbers, a particularly laborious task. Although Napier’s invention of logarithms overshadows all his other mathematical work, he made other mathematical contributions. These inventions included two kinds of burning mirrors, a piece of artillery, and a metal chariot from which shot could be discharged through small holes. John Napier was a mathematician and theological writer who  also invented the "Napier's bones" and made decimal points of common use in arithmetic and mathematics. John Napier (John Napier frequently signed his name "Jhone Neper, Fear of Merchiston", but later on we can find his name also as Napeir, Nepair, Nepeir, Napare, Naper, Naipper, Neperus, etc., the only form of Napier that for sure would not have been used in Napier's lifetime was the present modern spelling "Napier"!) He called it the Logarithm. They were usually used listed in tables in books, or as logarithmic scales on slide rules. Ada Lovelace has been called as "The first computer programmer".

In the former, he outlined the steps that had led to his invention. The world’s first practical calculator, one that could multiply, divide and find roots was developed in England during the latter part of the 16th century. One of these instruments made by Robert Davenport is the earliest known signed scientific instrument made in Scotland in about 1650. Logarithmic scales are also used for measurement, from decibels for sound to the Richter scale for earthquakes. John Napier invented “Logarithm” and “Napier’s Bones” John Napier was a Scottish mathematician and astronomer, best known for the invention of logarithms. Napier's father was only 16 when his son, John, was born. However, the considerable labour of calculating the revised logarithms was done by Briggs, or potentially unacknowledged students and helpers. He is however also frequently remembered for his invention, in 1617, of a calculating device that could be used to simplify the multiplication and division of large numbers. Explore the amazing collections of National Museums Scotland through films, animations and podcasts. Also called Rabdology (from Greek ραβδoς [rabdos], rod and λóγoς [logos], word). Soon after the publication of Napier’s Logarithmorum, other mathematicians developed logarithmic calculating devices. The Scottish mathematician John Napier was born to Sir Archibald Napier; the seventh Laird of Merchiston and Janet Bothwell in the Merchiston Castle, Edinburgh on August 1, 1550. About the same time William Oughtred (1575-1660) devised the circles of proportion, a circular slide rule. Around 1564, he left to study in Europe, on the advice of his uncle, the Bishop of Orkney. There were Greek scholars in Basel or Geneva, so he may have studied there. He explained his device in his book Rabdologiae; seu Numerationes per Virgulas libri duo (based on two volumes) in 1617. This is named after Napier. He was the eldest son of Archibald Napier and Janet Bothwell. Such tables took years to calculate and check. Famous Female Mathematicians and their Contributions (Part-I).
