The title of this article amused me: “Slide rule clings to life in the Internet Age“. I pictured a lonely slide rule, let’s say an “easy on the eyes” yellow model, hanging onto the bottom of a drawer for dear life. The article is actually very informative about the history of the slide rule, noting details of days past, such as a “techie’s” identity being based on what brand of slide rule they used. More recently, one collector gathered up 70 slide rules from eBay for about $1,300. There’s more where those came from. I wonder if the gigantic teacher’s model that was hanging over the blackboard of my junior high science classroom is still there. My teacher never actually used it; he kept it there for reminiscing about the good old days.
