Slide rule?  I doubt if I could remember how to use one.  A slide rule and a 
Castle book of logs were all that were permitted at exam time in the pre-
calculator days, and even for quite a while after calculators were available 
too.  My slide rule was my father's old wooden one which used to stick just 
where you wanted it.  My how times have changed !!
