Description
In 1960s, when the Cold War was at its peak and the worlds two superpowers were locked in a nuclear arms race, the U.S. Government Printing Office published a handy slide rule for estimating the effects of nuclear weapon explosions. It was available for $1.00 to anyone interested in "the study of effects data derived from nuclear weapons tests and from experiments designed to duplicate various characteristics of nuclear weapons".
Since then, many things have changed and this slide rule remains a relic of the past. Having become a collectors item, it is only available for a handy sum on auction sites and as a rather impractical web-based version. Until now.
This app is a faithful (although—for greater ease of reading—somewhat oversized) digital replica of the real thing. By responding to your touch much like the original plastic version, it brings this museum piece back to life.
With it you can evaluate 28 different effects of nuclear weapons, of which 13 relate to blast, 5 to thermal radiation, 1 to initial nuclear radiation, 2 to early fallout, 6 to crater dimensions, and 1 to fireball dimensions. Most of the parameters are presented as functions of range and yield.
The original slide rule was based on a book "The effects of nuclear weapons". This hefty 700+ page publication (which is in public domain, as well as the slide rule itself) is available at the support site of this app, together with links to the resources used to create this app.
