I'm not sure how many here remember the slide rule (SR). if you were in high school in the 60s then you would probably have some experience.
I went to HS in the 70s and never heard of the SR. Only 10 years ago did I discover them as a source of enjoyment. it feels pretty cool to know how to use some of the scales, and the more I use them the more I like SRs. Just yesterday I bought a full sized 10in SR used from a guy in manila. My new toy will be here in 2 days. Up until now I've been using a 5in model. I can hardly wait.
Anyway, a couple years ago I found this PDF book about how to use SRs for marine and aviation problems; from simple time, speed, distance calculations to cargo handling and trim. I wrote about it here at the time. However, maybe some of you missed that post. Just goes to show I'm still excited about the subject.
I'm thinking some of you might like to review the book, a free download, and discover how fascinating and ingenuous the SR really is. You don't need to have the same one they use in their example; any SR with similar basic scales will do.

This site is put together by a very nice man who assembled a collection of old books that keep my mind occupied.
Check it out and tell me if you don't agree that SRs are still useful... and they don't require batteries.
Cheers
