They were a bit out of date when I was studying, but there were still some lecturers who made the comment that you could tell the engineering students apart from the rest by the pocket full of slide rules. They needed more than one because they'd catch fire from all the furious calculations... I still use a circular one, though. My photo-voltaic cell light meter for my camera has one for you to calculate your exposure. ;-) -- Don't send private replies to my address, the mailbox is ignored.
