## Contributions of John Napier in Mathematics

- John Napier has done a great contribution in mathematics:
- Napier is considered as the first person to work with logarithms and even one of the first persons to work with decimals.
- Napier has made his own devices which would help him to resolve the issues of computation.
- He invented a well-known mathematical artifact
- the original old fashioned numbering rods are famously known as “Napier’s bones”. These rods help in computation. These Bones were originally used to calculate the Products and Quotients of the numbers.
- Napier figured out the worth of the latest development in that era in mathematics, especially those of symbolic index arithmetic, decimal fractions, and, to handling the issue of reducing computation.
- He appreciated that, for the most part, the mathematics Professionals who had indefatigable computations usually made in the context of trigonometry.
- Napier did a lot of contributions to trigonometric.
- Napier’s work,
*Mirifici Logarithmorum Canonis Descriptio*(1614) comprises ninety pages of tables of numbers associated with natural logarithms & fifty-seven pages related to explanatory matter and - Napier has beautifully written the theorems about spherical trigonometry, These theorems are now known as Napier’s Rules of Circular Parts.
- Napier considered
*A Plaine Discovery of the Whole Revelation of St. John*(1593) as his most important work. - Simon Stevin’s decimal notation was improved by Napier.
- Because of the Napier’s Bones, Fibonacci was able to use Lattice multiplication

## Quotes By John Napier

Seeing there is nothing, (right well-beloved students of mathematics,) that is so troublesome to mathematical practice, nor that doth more molest and hinder calculations, that the multiplications, divisions, square and cubical extractions of great numbers, which besides the tedious experience of time, are for the most part subject to many slippery errors, I began, therefore, to consider in my mind, by what certain and ready art I might remove these hindrances.

Arrange all these results as described, and you will produce a Table, certainly the most excellent of all Mathematical tables, and prepared for the most important uses.
