Etymology
The word "logarithmic" is derived from the Greek words "logos" (meaning "word", "ratio", or "proportion") and "arithmos" (meaning "number").
Meaning
Logarithm refers to a mathematical operation that expresses a number as a power to which a base must be raised to produce that number.
Origin
Logarithms were first developed independently by Scottish mathematician John Napier and English mathematician Henry Briggs in the early 17th century.
Napier, in his 1614 work "Mirifici Logarithmorum Canonis Descriptio", credited the astronomer Tycho Brahe with inspiring his work on logarithms. Brahe's extensive star observations required extensive calculations, which Napier realized could be simplified using logarithms.
Briggs further refined the concept and introduced the base 10 logarithms, known as common logarithms or Briggs logarithms. He also constructed tables of logarithms, making their use more widespread.
The concept of logarithms was a significant advancement in mathematics, as it simplified complex multiplication and division calculations and enabled scientists and engineers to perform complex calculations much more efficiently.
