My brother gave him his old slide rule! I can virtually guarantee that he was the only kid at the DI state tourney with a slide rule. smile

He's even sleeping with it, which I told my brother would be the case....

Now we just have to figure out how to use all the lines--we figured out multiplication, fractions, and pi times x, but it's a trig version so there are quite a few left to decipher that I don't know what answer I'm looking for so I can't just muddle through it. Great fun!
