He graduated in 1603 but he remained at Oxford until 1615 when he received a divinity degree. Gunter was ordained and became Rector of St George's Church in Southwark in 1615. He held this Church position until his death. In addition to being Rector of St George's Church, Gunter became professor of astronomy at Gresham College London in 1619, also holding this post until his death. A colleague and friend of Briggs , Gunter published seven figure tables of logarithms of sines and tangents in 1620 in Canon Triangulorum, or Table of Artificial Sines and Tangents . The words cosine and cotangent are due to him. He made a mechanical device, Gunter's scale, to multiply numbers based on the logs using a single scale and a pair of dividers. It was called the gunter by seamen and was an important step in the development of the slide rule. Gunter published his description in 1624 in

See Key People GUNTER'S CHAIN Gunter's chain n. Surveying a measuring instrument 66 ft (20.1 m) long, subdivided into 100 links (1 rod or perch = 25 links), each link being a short section of wire connected to the next link by a loop. It was long used for land surveying and became a unit of length (80 chains = 1 mile), but has now been superseded by the steel tape and electronic equipment. [Edmund Gunter, Engl. mathematician (1581-1626)] that you will faithfully assist the said Surveyor in his servis and that you will keep a true account of all Lines on measures by you taken and the same give up to said Surveyor at his desire according to your best Skill and ability. The Chainsmen's Oath Gunter's Chain is the most widely known unit of measurement that is universally attributed to the Art of Surveying . It came into common usage about 1700 a.d. and was the standard for measuring distances over 150 years. Until early in the 20th Century, it was universally made of iron or brass links. Because all of these chains were hand made, they rarely measured exactly the proscribed sixty six feet in length. Thus, the surveyor had to use a correction factor when translating his notes into a drawing. In later years, it became the Surveyor's Tape that was machine made and used sophisticated metallurgy to compensate for the small (but measurable) effect of temperature on the length of the tape. These chains are commonly found in both the full (100 link) and half (50 link) lengths.

Article taken from "Backsights" Magazine published by Surveyors Historical Society Gunter, Edmund (1581-1626), was of Welsh extraction, but was born in Hertfordshire in 1581. He was educated on the royal foundation of Westminster school, and in 1599 was elected a student of Christ Church, Oxford. After graduating bachelor and master of arts at the regular times, he took orders, became a preacher in 1614, and in November, 1615, proceeded to the degree of bachelor in divinity. Mathematics, however, which had been his favorite study in youth, continued to engross his attention, and on 6th March, 1619, he was appointed to the professorship of astronomy in Gresham College, London. This post he held till his death, which took place on 10th December, 1626. With Gunter's name are associated several useful inventions, descriptions of which are given in his treatise on the Sector, Cross-staff, Bow, Quadrant, and other Instruments . He had contrived his sector about the year 1606, and written a description of it in Latin. Many copies were transcribed and dispersed, but it was more than sixteen years afterwards ere he allowed the book to appear in English. In 1620 he published his Canon Triangulorum , a table of logarithmic sines and tangents (extended to 7 decimal places) for every degree and minute of the quadrant. In later editions an account of the general use of the canon is prefixed, and Brigg's logarithms of the first 1000 numbers are appended. There is reason to believe that Gunter was the first to discover (in 1622 or 1625) that the magnetic needle does not retain the same declination in the same places at all times. By desire of James I, he published in 1624

Children can opt to turn the paper pages and listen to the story read with different voices for each character. Or they can interrupt the read-aloud session to play with the magic pen (permanently attached with a wire). They can point the pen tip to any word on a page and hear it pronounced, or touch a picture and hear a sound effect (such as ''Strike one!'' for the baseball bat). Very similar to the popular Living Books computer games, this 10-by-11-inch book is more portable than a home computer.

More about napier's original logarithms ... oughtred william (1574-1660) A basic Introduction This is the story of numbers, our love-hate relationship with them, but in particular, it is the story of the attempts to tame them, to make them more manageable. The earliest recorded use of numbers and arithmetic is found on clay tablets from Mesopotamia (more or less equivalent to modern day Iraq). These tablets are more than 4500 years old, from the dawn of civilised urban existence and they deal with, guess what - accounts and tax records! Paying tax is surely one of the greatest joys of civilisation. Most early societies were hampered by the lack of a suitable way of expressing numbers. The Greeks, famed for their geometry, but not so good at algebra, used letters of the alphabet. The Romans had a particularly hideous system. These look pretty on a modern clock dial, but are useless otherwise - try multiplying XXVIII (28) by XXVI (26) to get DCCXXVIII (whatever that is).

The invention of the Slide Rule Edmund Gunter (15811626) Edmund Gunter's most important book entitled Description and use of the Sector , was first published in English in 1623. This has been described as ``the most important work on the science of navigation to be published in the seventeenth century." A sector is a mathematical instrument consisting of two hinged arms on which there are engraved scales which can be used to help with calculations. This is not a slide-rule; the single scale is used in conjunction with a pair of compasses. What makes Gunter's sector special is that it is the first mathematical instrument to be inscribed with a logarithmic scale to help solve numerical problems. In practice the points of the compass tend to damage the scales which reduces the accuracy of the instrument. William Oughtred (15741660) William Oughtred was a clergyman and keen mathematician. He is believed to have introduced the x symbol for multiplication in his book Clavis Mathematicae (Key to Mathematics), written about 1628 and published in London in 1631. This was a very important maths text book at the time. Newton read and was influenced by it for example. He is now generally though to be the inventer of the slide rule. Both straight and circular rules are described in a book with the title
