How was logarithm invented?

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. (Napier’s original hypotenuse was 107.)

How did John Napier invented logarithms?

Napier generated numerical entries for a table embodying this relationship. He arranged his table by taking increments of arc θ minute by minute, then listing the sine of each minute of arc, and then its corresponding logarithm.

Who invented logarithms India?

The Indian mathematician Virasena worked with the concept of ardhaccheda: the number of times a number of the form 2n could be halved. For exact powers of 2, this equals the binary logarithm, but it differs from the logarithm for other numbers.

Who invented Antilogarithm table?

In 1620 the first table based on the concept of relating geometric and arithmetic sequences was published in Prague by the Swiss mathematician Joost Bürgi. The Scottish mathematician John Napier published his discovery of logarithms in 1614.

Who developed the term logarithm?

John Napier invented logarithms, but many other scientists and mathematicians helped develop Napier’s logarithms to the system we use today. The first table of common logarithms was compiled by the English mathematician Henry Briggs.

Who invented logarithm table and what year?

Common logarithms use the number 10 as the base. Natural logarithms use the transcendental number e as a base. The first tables of logarithms were published independently by Scottish mathematician John Napier in 1614 and Swiss mathematician Justus Byrgius in 1620.

What was John Napier famous for?

John Napier, Napier also spelled Neper, (born 1550, Merchiston Castle, near Edinburgh, Scot. —died April 4, 1617, Merchiston Castle), Scottish mathematician and theological writer who originated the concept of logarithms as a mathematical device to aid in calculations.

Who invented Antilog table?

In 1614 (yes 1614) John Napier produced a work of natural logarithm tables. The paper contained ninety pages of tables and fifty seven pages of explanatory notes. This took him 20 years to create. Then Henry Briggs changed these original logarithms into a common (base 10) logarithm.
