Contribution to mathematics Napier devoted most of his leisure to the study of mathematics, particularly to devising methods of facilitating computation, and it is with the greatest of these, logarithms, that his name is associated. In early 1594, he started working on logarithms and by 1614; he got them published as Mirifici logarithmorum canonis description A Description of the Wonderful Law of Logarithms that proved to be his most popular and useful work. John Napier is regarded as the founder of what is now known as Napierian logarithm or Naperian logarithm. This is a translation of the old Scots that the Bishop of Orkney actually wrote. Before continuing we should comment on the spelling of John Napier. Napier's discussion of logarithms appears in Mirifici logarithmorum canonis descriptio in 1614. His life at the newly built castle at Gartnes left him with ample time for such varied interests as mathematics, agriculture, and religious politics.

Early Life John Napier was born on February 1, 1550, in Merchiston Tower, Edinburgh, Scotland. In the preface of the book Napier explains his thinking behind his great discovery we quote from the English translation of 1616 of the original Latin of 1614 :- Seeing there is nothing right well-beloved Students of the Mathematics that is so troublesome to mathematical practice, nor that doth more molest and hinder calculators, 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 in my mind by what certain and ready art I might remove those hindrances. I hope to see him this summer, if it please God, for I never saw a book which pleased me better or made me more wonder.

And having thought upon many things to this purpose, I found at length some excellent brief rules to be treated of perhaps hereafter. He did not inherit the estates of his father until 1608, when he was 58 years old. When the castle was completed in 1574, Napier and his wife took up residence there. He also made important contributions to spherical trigonometry, particularly by reducing the number of equations used to express trigonometrical relationships from 10 to 2 general statements. In 1572, he inherited the estates of his family.

In fact did make the difficult journey from London to Edinburgh to see Napier in the summer of 1615 would he have dreamed that now it takes 4 hours by train, rather than at least 4 days by horse and coach in those times. He promised to explain the method of their construction in a later work. Early life At the age of 13, Napier entered the University of St. It was here that he first became deeply interested in theology though he did not acquire in-depth knowledge in mathematics until later. We know that Napier spent some time at St Andrews University and he wrote himself many years later that it was in St Andrews that he first became passionately interested in theology.

What is known with certainty is that by 1571 Napier was back home and the next year married Elizabeth Stirling. In addition to mathematics, he also had deep interests in astronomy and religion. He was unpopular as manager of Bradford City, as the team was relegated to the now-defunct. In all he played more than 100 games at City, and served as manager, and assistant coach. He died on April 4, 1617, in Edinburgh in Scotland. As you will see, Robert did not have a son called Patrick.

His main claim to fame is the invention of Logarithms, but he achieved much more. But amongst all, none more profitable than this which together with the hard and tedious multiplications, divisions, and extractions of roots, doth also cast away from the work itself even the very numbers themselves that are to be multiplied, divided and resolved into roots, and putteth other numbers in their place which perform as much as they can do, only by addition and subtraction, division by two or division by three. Two years later an English translation of Napier's original Latin text was published, translated by Edward Wright. Married contract dated 14 June and 11 July, 1620 George Drummond of Balloch.

Archibald Napier was a justice-depute and was knighted in 1565. The device, known as Napier's bones or rods, evidences the creativity of his mind in practical mathematics. There is nothing in the register to show that this was John, eighth Laird of Merchiston, but it probably was, because it is unlikely that there were two John Napiers both married to an Agnes Chisholm there at the same timeJohn died on the 3 April 1617, and is reputedly buried in the crypt of St Cuthbert's Church formerly known as the West Kirk in Edinburgh and not in the family vault in St Giles' Cathedral in Edinburgh as is sometimes stated.

He was involved in mathematics research during his free time. He then married Agnes Chisom with whom they had ten children.
