Hello all,

I was just reading through one of my MAKE magazines, and noticed the article written solely about Dean K. It stated in this article that he had a 6’ slide-rule that he used to instruct the reported on the finer points of Slide-ruling. I, however only have a smaller, antique slide rule and THIS java applet, and absolutely no understanding of how to use one… can anyone point me in the direction of online tutorials/white papers on how to do this? Any help would be greatly appreciated as my curiosity is now peaked :smiley:

Thanks in advance,

-Cody C.

Ahh, the days of the slide rule! We learned math a whole different way, just to accomodate the tool. And I even know where my slide rule is, and have the 1947 K&E slide rule that was my dad’s. Leather case and all, but somewhere the glass slide was cracked. :frowning:

I also remember my first scientific calculator, and yes it was a HP! Bought for me by my rich uncle before I went off to engineering school. For the longest time I used the slide rule to make sure the calculator was correct! :rolleyes: So I really enjoyed the irony of the slide rule tutorial at the Museum of HP calculators.

Have fun with the slide rule, Cody! I’d be interest to hear if you could figure it out on your own!

I remember making on years ago as sort of a hands on thing to do in math class. Thats about the extent of my knowledge on slide rules.

Purdue has a nice collection of slide rules in the Potter Engineering Library. The collection features slide rules from many astronauts including Neil Armstrong.

Funny you should mention. This watch was on my christmas list this year. Circular sliderule on the rim of the watch. Perfect for all your unit conversion and multiplication needs.

I need to update my web page, and put a few of our slide rules, and more of our calculators, on it. It does have my old Casio CFX200 watch, and my HP-11c (which sadly quit working not long ago). But it doesn’t have any of the slide rules, or TI calculators…

(my brother is in the MAKE book, something I’m kind of proud of)
