Just verified that the one in my desk drawer was still there.

I use it once or twice a year, just to stay slightly familiar. It's also a good thing to show to the young whippersnappers that think that a desk calculator is old school.

Designing a slide rule is easy. For the basic scales, just take the logarithm of the number in the base desired, then space marks out on the slide according to logarithm while labeling them with the initial numbers. Make two of them, face them to each other, and that's your slide rule.
