This was how I (and many others) learn about interpolation. I also learned to make log/log paper with it. A few years later, my grandfather died when I was in engineering school. My grandmother sent me his slide rule to remember him by (which I still have). Although she did not know that at the time, I already owned the then hot item, a TI SR50 scientific calculator - which I paid the $150 in 1972 dollars (about $900 in today's money). I also got his drafting table, but I no longer have that. The slide rule is made of ivory on top of metal (I think bronze but I never had it checked). It was probably made in the 1920s. It stays in a box in desk ;-) A slightly, sad part is I don't think either of my kids knows how to use it, and while both have degrees in science, I don't think either wants it. -------------- next part -------------- An HTML attachment was scrubbed...
