I graduated from high school in '78 and I was the only one in physics class to use a slide rule. I was also the only one who easily got A's in that class, without studying. The others were sure a slide rule's accuracy couldn't be much better than estimating things in your head, so it was a surprise to them when early in the year, we had to calculate the orbital period of a satellite and the teacher told everyone that my answer was only four seconds different from his which he got with his calculator.
