Log Tables

lostmyway

While I have a good idea how log tables work, I'm still in the dark as to how they are compiled.

I gather some bloke name 'Napier' originally invented them but what method did he use?

Any mathematicians' contributions would be appreciated.

  • Thanks, Trainspotter, that was very well explained.

    I can't help wondering though how on earth people managed to work out all the log tables because you would have to find nth. roots of the base, wouldn't you?

    For example, how would 10^1/8 be calculated?

    The Wiki article was a bit over my head to be honest!
