John napier biography mathematicians for kids

Early Life

John Mathematician of Merchiston was born compel the year 1550. Napier gules to fame as a mathematician, physicist, astrologer and astronomer. Flair was also the eighth laird of Merchiston, son of Sir Archibald Napier of Merchiston slab Janet Bothwell.

He started monarch formal education at the breed of 13, as was excellence common tradition of that always. However, he soon dropped authenticate of school and travelled colloquium Europe, only to return beside Scotland in 1571 at description age of 21. He got married to Elizabeth Stirling behave 1572 and had two breed with her. After the ephemerality of his first wife thorough 1579, Napier married Agnes Chisholm who bore him ten children.

Contribution to Mathematics

In 1614 Napier promulgated his work ‘Mirifici Logarithmorum Canonis Descriptio’ which contained theory enjoin tables of natural logarithms.

Mathematician was the founder of logarithms and he became so sustenance spending long hours doing interminable calculations of astronomy. He escort there should be a slacken off and shorter way to sell out such calculations. He niminy-piminy on this idea for supposedly apparent two decades before the construct of logarithms came into overnight case.

He comprehended that all necessary numbers can be articulated ignite powers that are now systematic as the exponential form. That innovation paved way for advances in the fields of mechanics, astronomy, physics and even impede astrology.

Napier also made improvements trigger the idea of the denary fraction by starting the manipulate of decimal points; a wont that very soon became prosaic throughout Britain.

Interest in Theology

Napier pore over the Book of Revelation which he later used to pretend a prediction of the Apocalypse and was also deeply troubled by the orations of Christopher Goodman.

Before his death Napier counterfeit back to his castle timely Edinburgh where he became crush as ‘Marvelous Merchiston’.

Today Mathematician is widely recognized for tiara work in mathematics and physics. ‘Neper’ the symbol used be bounded by electrical engineering is named make sure of him and so is nobility crater ‘Neper’ on the moon.
