A biography of john napier a scottish mathematician

John was the 8th Laird of Merchistoun. Today, he is best known as the inventor of logarithms.

Early Life John was born in 1550 in Edinburgh. Sir Archibald was only 16 years when his son John was born. As a common practice amongst members of the nobility, John did not join school until he was 13 years old.

However, he did not remain in school for long either. It is believed that he dropped out of school in Scotland and travelled to Europe to further his studies.

Some historians claim that he studied in some universities on Italy and France. In 1571, when he was 21 years, John Napier went back to his homeland and married Elizabeth Stirling after one year. He also bought a castle at Gartness in 1574. In 1608, he lost his father and John and his family moved into Merchiston Castle located in Edinburgh. He remained here for the remainder of his life. This book contained 57 pages of different explanatory matter and 90 pages of tables of numbers that are related to natural logarithms.

The book contains a great discussion of different theorems in spherical trigonometry.

In 1615, Henry Briggs, a prominent English mathematician, visited John. Napier also made further contributions in mathematics.

Early life

Napier and Theology John had a great interest in the Book of Revelation. He was also influenced by sermons of Christopher Goodman and therefore, he developed a very strong anti-papal reading. He used the Book of Revelation for a timeline of sorts in order to predict the Apocalypse. He also applied Sibylline Oracles to calculate the date the world would end.

He believed that this would occur either between 1688 or 1700.

Theology and inventions

He even dated the seventh trumpet to 1541. He advised the king to reform the universal enormities of the country beginning with his house, family, and court. The book was a great success both at home and abroad. In 1594, Napier revolted against this using a book. John decided to set up four new types of weapons to make this struggle even more powerful. His weapons included an artillery piece.

This was a kind of battle vehicle covered with plates of metal and had very tiny opening for emitting odious smoke, firepower two 2 kinds of burning mirrors. This vehicle was driven by men inside. Soon after, the called the Spanish conquest was over and this meant John had to go back to his work.

Napier and the Occult Apart from his mathematical and religious interests, John was often seen as a magician. He is actually thought to have dabbled in necromancy and alchemy. Many people said that he used to travel around with a black spider in a tiny box. Many also believed that his black rooster was his familiar spirit.

His contributions in logarithms are given credit as the largest single factor in the adoption of decimal arithmetic. Today an alternative unit to the decibel is used in electrical engineering, the neper. This is named after Napier.

The crater Neper on the Moon is also named after him. His wife died in 1579 and he remarried Agnes Chisholm.
