Archibald Napier was a justice-depute and was knighted in 1565. It's about time someone wrote a book on this subject for a general audience. Shortly after Napier matriculated his mother died. Some historians believe that he may have traveled to Switzerland to be taught, since there were small numbers of scholars specializing in Greek in both Geneva and Basel. I suppose that there are few indeed of the present generation who have read, or even heard of, the book; whatever its merits may have been they do not appeal to the modern mind.

His surname appears in a large variety of different spellings.
Two years later an English translation of Napier's original Latin text was published, translated by Edward Wright. Many quantities, such as sound loudness, Earthquake strength, and pH, are measured using logarithmic scales. He returned home in 1571 at the age of 21 and the following year he married Elizabeth Stirling, daughter of a Scottish mathematician James Stirling. In 1615 he was visited by English mathematician, Henry Briggs, and Napier assigned Briggs the task of revising the computation tables. Nevertheless, it was in the field of mathematics to which he was attracted. After her death in 1579, he married again and had ten more children with his second wife, Agnes Chisholm. Elizabeth died in 1579 and so John later married Agnes Chisholm and conceived ten children and earlier had two with Elizabeth.
He proposed several military inventions including burning mirrors that set enemy ships on fire, special artillery that destroyed everything within a radius of four miles, bulletproof clothing, a crude version of a tank, and a submarine-like device. Napier presented a mechanical means of simplifying calculations in his Rabdologiae published in 1617. As a Mathematician, the highlight of John Napier's life was the creation of logarithms and the decimal notation for fractions. Napier also found exponential expressions for trigonometric functions, and introduced the decimal notation for fractions. Napier also popularized the use of decimals, which were not commonly used before Napier's time.
Readers will gain a deep understanding of the background and uses of the logarithm, as well as the significance of Napier's achievement. A logarithm is the exponent to which a number called the base must be raised in order to give a specific value. In 1614, he published the work that was to give him lasting fame: an outline of the basic principles behind what came to be known as logarithms. Lesson Summary Even though Napier was not a professional mathematician and never graduated from a University, he was still able to make a significant impact on the world. The early life of John Napier is shrouded in mystery.
He was appointed Master of the Mint in 1582. Elizabeth died after giving birth to two children, after which Napier married Agnes Chisholm, with whom he had ten children. He complained that no considerable advance had been made in Geometry beyond Euclid, without taking any notice of what had been done by Archimedes and Apollonius. He brings Mr into my Lord's chamber, where almost one quarter of an hour was spent, each beholding other with admiration, before one word was spoken. Logarithms and exponential notation made calculations much quicker and was important to scientific advances in astronomy, and physics.
He popularized the used of decimals and invented several devices and methods to aid people in performing complex mathematical calculations. Napier was many things, including a Protestant theologian and a prominent member of the Scottish landed gentry. He married the following year. Fact 3 It is said that he would travel with a black spider in a small box, since he was considered to be a magician by some people. However, he may have spent some time at the Edinburgh High School, and some little time studying in France.
In 1608, he lost his father and John and his family moved into Merchiston Castle located in Edinburgh. Napier's discussion of logarithms appears in Mirifici logarithmorum canonis descriptio in 1614. 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. His family had owned the Merchiston estate from the 1430s when one of his ancestors acquired the estate, becoming the first Napare of Merchiston. He advised the king to reform the universal enormities of the country beginning with his house, family, and court.
John Napier 1550—1617 is celebrated today as the man who invented logarithms—an enormous intellectual achievement that would soon lead to the development of their mechanical equivalent in the slide rule: the two would serve humanity as the principal means of calculation until the mid-1970s. He not only liked to look at the stars, but he did a lot of research on getting calculations of very large numbers. He was also influenced by sermons of Christopher Goodman and therefore, he developed a very strong anti-papal reading. Both of his books have been translated into English and are available on the internet. Napier did not attend school until the age of 13, after which he travelled around in Europe, acquiring his education at different places. Contributions to Mathematics In 1614, John published his first work — Mirifici Logarithmorum Canonis Descriptio. Meanwhile, Napier was making a further name for himself both in Scotland and abroad with his fiery denunciation of the Roman Catholic Church, to which he was vehemently opposed.
He was therefore, when in deep study, sometimes under the necessity of desiring the miller to stop the mill that the train of his ideas might not be interrupted. Pasles, author of Benjamin Franklin's Numbers. John Napier invented a hydraulic screw with a revolving axle that lowered water levels in coal pits. Andrews, but his stay appears to have been short, and he left without taking a degree. Napier's study of mathematics was only a hobby and in his mathematical works he writes that he often found it hard to find the time for the necessary calculations between working on theology. However, back in the sixteenth century, there were no calculators! Napier improved Stevin's decimal notation and used it extensively in his calculations.
John Napier was actively involved in politics till the end of his life and died in 1617 at the age of 67. Napier had a variety of interests such as religion, mathematics, astronomy and physics. Mark Napier suggests that John Napier deliberately played upon the primitive beliefs of his servants by going round with a cock which he had covered in soot. 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. 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. He speaks of the εὕρηκα of Archimedes in a manner which implies that he did not clearly appreciate either the problem to be solved or the principles upon which the solution depended.
