More than just logarithms. Slide rules force one to understand the problem being solved. It's far too easy to come up with the wrong answer (to 9 digits of "accuracy") using a calculator, with total confidence in the result.

There were several large wooden slide rules made by Pickett and other manufacturers as teaching props. My son has one that is a straight forward two scale Log-Log that his school gave him. He used to use a slide rule in science and math classes when his classmates all were using programmable calculators. He usually had answers before anyone else did. Sadly, they are just an interesting collector piece for hobby room walls now.
