Logarithms were in use for hundreds of years until mechanical machines were able to calculate larger numbers in the late 19th century, and eventually, computers took over the task in the 20th century.

The virtue of logarithms for multiplicative arithmetic is that the product of two numbers A and B can be found by adding their logarithms. If A x B = C, then log 10A + log 10B = log 10C.

Because logarithms relate geometric progressions to arithmetic progressions, examples are found throughout nature and art, such as the spacing of guitar frets, mineral hardness, and the ...

Logarithms are a common idea today, even though we don’t use them as often as we used to. After all, one of the major uses of logarithms is to simplify computations, and computers do that jus… ...

Today’s commonly used base 10 logarithms were introduced in primitive form by Henry Briggs after Napier died in 1617. (Briggs acknowledged, though, that it was Napier’s idea to do so.) ...
