Logarithms are everywhere in mathematics and ... into a calculator of some description and hit ‘calculate’. How do we even know that the answer which it returns is remotely correct?

After all, one of the major uses of logarithms is to simplify computations, and computers do that just fine (although they might use logs internally). But 400 years ago, doing math was painful.

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.) ...

And so, countless popular science books contain potted guides to using exponential notation and interpreting logarithmic axes on graphs. Why do they need to do this? Because logarithmic scaling is ...
