What did John Napier accomplish?
John Napier was a Scottish scholar who is best known for his invention of logarithms, but other mathematical contributions include a mnemonic for formulas used in solving spherical triangles and two formulas known as Napier's analogies.
Who contributed to the development of computers?
English mathematician and inventor Charles Babbage is credited with having conceived the first automatic digital computer. During the mid-1830s Babbage developed plans for the Analytical Engine.
Why did Napier create logarithms?
The Scottish mathematician John Napier published his discovery of logarithms in 1614. His purpose was to assist in the multiplication of quantities that were then called sines. The whole sine was the value of the side of a right-angled triangle with a large hypotenuse.
How did John Napier impact the world?
Inventing a portable calculating tool – 'Napier's bones'.
He is widely considered to be the first Scotsman to have made a significant contribution to scientific learning. He was respected by mathematicians and scientists worldwide, notably Galileo, Johannes Kepler and Isaac Newton. Napier invented logarithms in 1614.
Who invented Napier bones?
The Scot, John Napier, invented these strips (originally made from bone) about 400 years ago to help calculate multiplication and division.
What is the meaning of Napier?

What is Napier bones used for?
Napier's bones is a manually-operated calculating device created by John Napier of Merchiston, Scotland for the calculation of products and quotients of numbers. The method was based on lattice multiplication, and also called 'rabdology', a word invented by Napier.
What did John Atanasoff invent?
John Vincent Atanasoff is known as the father of the computer. With the help of one of his students Clifford E. Berry, in Iowa State College, during the 1940s, he created the ABC (Atanasoff-Berry Computer) that was the first electronic digital computer.
