Calculating on Slide Rule and Disc
“2 x 3 ... approximately 6” Portrait of an Era
by IJ. Schuitema and H. van Herwijnen
Author IJzebrand
Schuitema owns one of the largest slide rule collections in the world.
In the course of his collecting, he came upon rules that were unknown
to him and that excited his curiosity. This book is a compilation
of the articles he wrote about these wonderful slide rules, each one
made for a specific and unique use, and about the men who designed
and manufactured them. There is the slide rule that computes road
curvature, one that calculates for sewerage applications, one that
provides navigational information for flyers, one for brewers that
computes barley malt, water, hops, and yeast and then takes into account
time, temperature and pressure and there are many, many more. Ir.
Schuitema was fortunate to have as his associate in this enterprise
Herman van Herwijnen, who describes himself as a slide rule collector
and computer freak. He has compiled a marvelous CD, designed for the
PC and included with the book, featuring an enormous number of photographs
(in full color and from all sides and angles) of all the rules mentioned
in the book, as well as a great many additional ones. Each rule is
accompanied by a description – material it is made of, size, name,
etc. Each picture can be enlarged several times, so that every detail
is seen.
