All About Slide Rules Book (PDF)

[David Shenk]

Very well done PDF, thank you for the link.

I inherited my dad's slide rules and had them out one day with a booklet that teaches you how to use them (I didn't know). My 10 and 12 year olds had never seen them before and spent a good hour following the book and making calculations. They had such a good time they occasionally bug me to get them out again. What's old is new again.
