Edmund Gunter Born: 1581 in Hertfordshire, England Died: 10 Dec 1626 in London, England Previous (Chronologically) Next Biographies Index Previous (Alphabetically) Next Main index Version for printing Edmund Gunter 's father was Welsh, coming from Gunterstown. Edmund attended Westminster School, then entered Christ Church, Oxford on 25 January 1600. He graduated in 1603 but he remained at Oxford until 1615 when he received the divinity degree of BD. Gunter was ordained and in 1615 became Rector of St George's Church in Southwark and of St Mary Magdalen, Oxford. He held this position in the Church until his death. Gunter was a friend of Briggs , and would spend much time with him at Gresham College discussing mathematical topics. When the professor of astronomy at Gresham College resigned in 1620 Gunter was appointed to fill the vacancy, largely on the recommendation 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 (see [8] for details). The words cosine and cotangent are due to him.

Gunter's measurement From Wikipedia, the free encyclopedia. A Gunter's chain that belonged to John Johnson (1771-1841), Surveyor General of Vermont. Source: Smithsonian Institution Gunter’s measurement , sometimes Surveyor’s measurement , is a geodetic system, formerly popular in Britain and its (former) colonies. It was developed in the 17th century by Edmund Gunter and is still in use today in the United States of America Gunter used an actual measuring chain of 100 links. These, the chain and the link , have become units of their own. A Gunter’s chain is 4 rods long, with the rod being a standardized measurement of 5 1/2 yards or 16 1/2 feet. This rod is also called a perch or a pole. The statute rod was codified in English law at least as early as Edward I , and possibly predates the Norman conquest Gunter’s chain is 22 yards feet , or 20.1168 metres

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).

38. The Invention Of The Slide Rule and use of the Sector edmund gunter (15811626). Journal of Navigation, 34(3)363367, (1981).......edmund gunter s most important book entitled http://web.mat.bham.ac.uk/C.J.Sangwin/Sliderules/inventrule.html

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
