Etymology:
Meaning:
Logarithm is a mathematical term that refers to the power or exponent to which a base must be raised to produce a given number.
Origin:
The term "logarithm" was coined by the Scottish mathematician John Napier (1550-1617).
Napier's Concept of Logarithms:
Napier's original conception of logarithms involved a series of geometric proportions. He envisioned a line segment of unit length being divided into equal parts, forming a geometric progression. The numbers associated with each division represented the logarithms of the corresponding ratios.
Development of Modern Logarithms:
In the years following Napier's invention, other mathematicians, including Henry Briggs (1561-1630), developed the concept of common logarithms, where the base is 10. This simplified logarithmic calculations, making them more practical for various mathematical and scientific applications.
