New Sliderule Design: Sliderules are in
many ways as powerful as scientific calculators, capable of applying
several functions and inverse functions. My idea is to have a
paper-thin kind, formed with a opaque "back" and a transparent
"window", with the same or similar functions. Functions can be
applied by lining up the appropriate scales (rather than with a
slider), and because the two can be disconnected, one can combine
ideas from sectors for trigonometric functions. Here is C code to generate a Postscript file to be printed on paper and
transparency. More scales/functions need to be added.
