Nuclear slide-rules from a time after nukes and before pocket-calculators
The Oak Ridge Associated Universities website has a splendid gallery of nuclear-age slide-rules (as Mr Jalopy notes, these are artifacts from an age after nukes but before pocket calculators) -- mostly circular cardboard calculators that help you compute the size of the crater generated by the nuke that touches off WWIII. Shown here, the 1960 Nuclear Bomb Effects Computer by EG&G.Nuclear Slide Rules (via Dinosaurs and Robots)
As a convenience to those interested in the effects of nuclear weapons, this circular computer was designed to make data easily available on various weapon effects - some as functions of both yield and range and others on yield alone . . . The weapons data incorporated in this computer were taken from the very informative and useful text, The Effects of Nuclear Weapons, edited by Samuel Glasstone for the Armed Forces Special Weapons Project of the Department of Defense.
