I think we're now dating ourselves. The kids coming out of school now  
don't have a clue what a slide rule is or a log table either. My  
freshman chemistry teacher spent the first two weeks of the course  
teaching us how to use a slide rule. If you had his class before, you  
were excused. If you couldn't use the slide rule you failed the  
course. You couldn't finish the exams in time.
