Yes, I had only bought once or twice from Sphere, but Walt and Susan did include some useful goodies.? Say, that NYT article mentioned slide rules made out of bamboo, and I'd never thought about it until today, but my dad's old slipstick from the 1960s had the open grain at the ends and was almost certainly made of bamboo!? I'm too young (born in 1965, engineering school 1983-1991 including grad school) to have used one, but I'm starting to think I missed out.? Say, what make and model would you folks recommend for an EE with a bent toward RF, microwaves, and fiber optics?? Steve, interestingly enough, my dad is a chemist turned software engineer who used to teach p-chem! Definitely not my thing, and I jumped to EE after starting freshman year as a biochemistry major; those chem labs blew it for me.?
