What was the surname of the Scottish mathematician who discovered logarithms in 1613 ?
History of logarithms 1544 which contains a table of integers and powers of 2 that has been considered an early version of a logarithmic table. The method of logarithms was publicly propounded by John Napier in 1614, in a book entitled "Mirifici Logarithmorum Canonis Descriptio" ("Description of the Wonderful Rule of Logarithms"). The book contained fifty-seven pages of explanatory matter and ninety pages of tables related to natural logarithms. The English mathematician Henry Briggs visited Napier in 1615, and proposed a re-scaling of Napier's logarithms to form what is now known as the common or base-10 logarithms. Napier delegated to Briggs the computation
History of logarithms published "Arithmetica integra" in Nuremberg in 1544, which contains a table of integers and powers of 2 that has been considered an early version of a table of binary logarithms. In the 16th and early 17th centuries an algorithm called prosthaphaeresis was used to approximate multiplication and division. This used the trigonometric identity or similar to convert the multiplications to additions and table lookups. However, logarithms are more straightforward and require less work. It can be shown using Euler's formula that the two techniques are related. The Swiss mathematician Jost Bürgi constructed a table of progressions which can be considered
