As the parent of teenagers, I find myself needing examples to explain concepts such as logarithms. Visual aids help, and a slide rule was the perfect tool for showing that multiplication of two numbers can be accomplished by adding the logarithms of the numbers.

Finally, I found my father's slide rule (it said it was patented in 08) in a box and explained how to use the cursor on the slide rule to find the answer.
