# How to use a Slide Rule

In my show 1664, â€œLife and Times of a Geek part 1â€, I spoke about using a slide rule as a schoolboy. As a consequence, I was asked if I would do a show on slide rules, and this is it (after a rather long delay).

## Long notes

I have written out a moderately long set of notes for this episode and these are available here https://hackerpublicradio.org/eps/hpr2166/full_shownotes.html.
