This last year I started collecting slide rules.
I am 38 years old. I only used them briefly
in junior high because of a math teacher who felt
that much was being lost to the reliance on using
calculators and PCs to do math. I guess I have caught some srt of meme-virus.
Slide Rule Universe is one of the websites out there for addicts like myself.
Slide Rule Emporium specializes in Pickett slide rules. The Pickett N600-ES was carried on Apollo 13... And the Sama & Etani 600 is still used by some at NASA...
