Logaritmer - John Napier
John Napier var ophavsmand til verdens første logaritme. Historien går over Tycho Brahe og dennes regnemester Longomontanus
http://www.matematiksider.dk/napier.html

Extractions: Skotten John Napier (1550 - 1617) tildeles normalt æren for at have indført logaritmerne. Således udgav han i 1614 Mirifici Logarithmórum Canónis Descriptio , en tabel, som kunne angive logaritmer med en nøjagtighed på 7 cifre. Man mener, at det tog Napier omkring 20 år at beregne tabelværdierne. Udover at interessere sig for matematik var Napier en idérig og engageret person. På sit gods, Merchiston castle, gjorde han opfindelser til lettelse af hverdagen og han deltog med passion i de intellektuelle diskussioner indenfor politik og religion. Han var en ivrig modstander af katolikkerne og kaldte paven for antikrist. Hans litterære værk A Plaine Discovery of the whole Revelation of Saint John fra 1593 gjorde ham faktisk mere kendt blandt hans landsmænd end logaritmetabellerne gjorde.

Extractions: John Napier 's father, Archibald Napier, was an important man in late 16th century Scotland. His family had owned the Merchiston estate from the 1430s when one of his ancestors acquired the estate, becoming the first Napare of Merchiston. (We shall comment shortly on the different spellings of Napier's name.) The family also owned estates at Lennox and at Menteith and a residence at Gartness. Archibald Napier married Janet Bothwell, the sister of the Bishop of Orkney, in 1549 when he was only 15 years old. Their son John Napier was born the following year. Archibald Napier was a justice-depute and was knighted in 1565. He was appointed Master of the Mint in 1582. Before continuing we should comment on the spelling of John Napier. The name John is most easily dealt with as John Napier, and almost everyone else around his time, used the old spelling "Jhone". His surname appears in a large variety of different spellings. The forms Napeir, Nepair, Nepeir, Neper, Napare, Naper, Naipper are all seen but John Napier would most commonly have been written Jhone Neper at that time. The only form of Napier that we are sure would not have been used in Napier's lifetime was the present modern spelling "Napier"! Little is known about John Napier's early years. One of the few scraps of information that we have is from a letter from the Bishop of Orkney, John's uncle, to Archibald Napier written when John was eleven years old:-

Extractions: John Napier John Napier was born in Merchiston, Edinburgh in 1550. He matriculated at St Salvator's College, University of St Andrews in 1563. Very little is known about him during this period although he did study in Paris and travel in Italy and Germany before returning to Scotland to marry in 1571. This was the period of the Scottish Reformation and Napier was very committed to the Protestant cause. In 1594, he wrote his Plaine Discovery of the whole Revelation of Saint John which he addressed to King James VI in a letter. This was the first Scottish book on the interpretation of scripture and has a significant place in the history of theology in Scotland. John Napier is best known as the inventor of Logarithms. While important steps in the theory had been taken in the sixteenth century, notably by Burgi, it was Napier who first brought the subject, in any large way, to the attention of mathematicians. This was in his Mirifici logarithmorum canonis descripto (1614), the first important work on mathematics produced in Great Britain, and one which inspired Briggs, the professor of geometry at Gresham College, London, to develop the system of common logarithms with the decimal base. Napier also invented Napier rods or bones for use in multiplication, a development of a well-known Oriental method, and a number of formulae in trigonometry relating to circular parts. His other mathematical works include De arte logistica (1573 but not published until 1839)

Extractions: John Napier was born into a wealthy family, as his father was Master of the Mint in Scotland. Napier entered St. Andrews University at the age of 13, though he left to study in Europe before completing a degree. It is likely that he studied at the University of Paris, and perhaps Italy and the Netherlands as well. Napier took part in the religious controversies of the time. He had been a fanatical Protestant from his days as an undergraduate at St Andrews. He married, built himself a castle, and took over the job of running his estate. This task he took very seriously and, being a great genius as an inventor, he applied his skills to these tasks. He approached agriculture in a scientific way and he experimented with improving the manuring of his fields. 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. He is best known for his invention of logarithms. Napier's discussion of logarithms appears in a text in 1614. Two years later an English translation of Napier's original Latin text was published. Unlike the logarithms used today, Napier's logarithms are not really to any base although in our present terminology it is not unreasonable to say that they are to base 1/e. His notation was Nap.log x. Briggs had suggested to Napier that logs should be to base 10, and Napier suggested in return that Nap.log 1 should be zero. Briggs later made tables of these. Napier also presented a mechanical means of simplifying calculations in 1617. He described a method of multiplication using "numbering rods" with numbers marked off on them. To multiply numbers the bones were placed side by side and the appropriate products read off. They were made of ivory, and because they looked like bones, they are now known as Napier's bones.

JOHN NAPIER PHILOSOPHER and MATHEMATICIAN INVENTOR of LOGARITHMS INVENTOR of the DECIMAL POINT J ohn N apier, eighth Laird of Merchiston was born in Merchiston Tower in 1550 and was known as the 'Marvellous Merchiston', a title which was well-deserved, for his genius and imaginative vision encompassed a number of fields. At the age of thirteen Napier went to St Salvator 's College in St Andrews but left without graduating. If is thought that he then travelled in Europe between 1566 to 7577, perhaps studying in Paris or Holland though there is no corroborative proof of this. It is interesting to note that these were difficult years for Scotland with the dethronement of Queen Mary on the murder of her husband Darnley and the subsequent coronation of her infant son, James. In 1572, he married his second wife, Agnes Chisholm by whom he had five sons and five daughters ( his first wife Elizabeth, from whom he had one son, died within a year ). He died in 1677 and is buried in St Cuthbert 's Churchyard in Edinburgh. Napier is relatively little known outside mathematical circles where he made what is undoubtedly one of the single greatest advances in the history of mathematics. He can be placed within a short lineage of mathematical thinkers, beginning with Archimedes in ancient times and by Newton and Einstein in modern times. Without Napier 's work on logarithms it is difficult to imagine how Kepler and Newton could have made their great advances in later times. His work

Extractions: Home Biography A Description of the Admirable Table of Logarithms Napier's Rods ... References J ohn Napier was a famous Scottish theologian and mathematician who lived between 1550 and 1617. He spent his entire life seeking knowledge, and working to devise better ways of doing everything from growing crops to performing mathematical calculations. Napier was so intelligent, many of the locals believed him to be in league with the Devil, but such claims never went further than the rumor mill, In fact, Napier himself, and ardent protestant, accused the Pope of being the Anti-Christ, and in a document he considered to be his finest achievement, went as far as predicting the end of the world. In addition to being an educated man, Napier was also a nobleman, a baron, the 7th Laird of Merchiston, and owner of a considerable estate. Napier was loved by all, and he was respected by many illustrious scientists and mathematicians of the age, to the point of being considered some sort of scientific superstar, with "fans" awaiting his next publication the way we await the release of a movie or pop album. Napier's "greatest hits" include such groundbreaking texts as A Description of the Admirable Table of Logarithms, and his invention of divining rods used as multiplication tables.

In that year he was made commanding officer in the northern district, and found his command no sinecure, owing to the turbulent state of the Chartists in the towns of Yorkshire, Lancashire and the Midlands. His behaviour during the tenure of his command is described by William Napier in his life of his brother, and his inability to hold a command which did not carry supreme authority is plainly portrayed. In this particular instance his sympathies were on the popular side, and, though he maintained law and order with the necessary rigour, he resigned as soon as the crisis had passed, and went to India. He was stationed at Poona, and in September 1842, when troubles were expected there, was ordered to Sind. In 1549 Archibald Napier, at the early age of about fifteen, As already stated, John Napier was born in 1550, the year in which the Reformation in Scotland may be said to have commenced. In 1563, the year in which his mother died, he matriculated at St Salvators College, St Andrews. He early became a Protestant champion, and the one extant anecdote of his youth occurs in his address to the Godly and Christian reader prefixed to his Plaine Discovery. He writes: In my tender yeares, and barneage in Sanct-Androis at the 1 The descent of the first Napier of Merchiston has been traced to Johan le Naper del Counte de Dunbretan, who was one of those who swore fealty to Edward I. in 1296 and defended the castle of Stirling against him in 1304; but there is no authority for this genealogy, The legend with regard to the origin of the name Napier was given by Sir Alexander Napier, eldest son of John Napier, in I625, in these words: One of the ancient earls of Lennox in Scotland had issue three sons: the eldest, that succeeded him to the earldom of Lennox; the second, whose name was Donald; and the third, named Gilchrist. The then king of Scotland having wars, did convocate his lieges to battle, amongst whom that was commanded was the earl of Lennox, who, keeping his eldest son at home, sent his two sons to serve for him with the forces that were under his command. .

Extractions: John Napier and Napier's Bones In the early 1600s, a Scottish mathematician called John Napier invented a tool called Napier's Bones, which were multiplication tables inscribed on strips of wood or bone. Napier, who was the Laird of Merchiston, also invented logarithms, which greatly assisted in arithmetic calculations. In 1621, an English mathematician and clergyman called William Oughtred used Napier's logarithms as the basis for the slide rule (Oughtred invented both the standard rectilinear slide rule and the less commonly used circular slide rule). However, although the slide rule was an exceptionally effective tool that remained in common use for over three hundred years, like the abacus it also does not qualify as a mechanical calculator. a See also: Leonardo da Vinci's mechanical calculator Wilhelm Schickard's mechanical calculator Blaise Pascal's Arithmetic Machine Gottfried von Libniz's Step Reckoner ...

This great Scot, a reclusive inventor who developed bulletproof clothing in addition to the ivory ÒbonesÓ with which he performed his logarithmic calculations, and who was said to keep a black cockerel as his familiar, can also be called a poet thanks to a single surviving work: ÒA Plaine Discovery of the Whole Revelation of St. JohnÓ (1593).
