In the early 17th century, both Jost B rgi and John Napier dared to invent a logarithm table whose construction required tens of thousands of computing steps.
These tables reduced computing effort for multiplication and division by an order of magnitude.
Indeed, their invention launched a computing revolution that continues to this day.
The book tells the story of B rgi's and Napier's work, and how Henry Briggs built on Napier's idea, creating a table of logarithms that was easier to use.
