It is hard to understand how we survived the Cold War years with the vast proliferation of these weapons.
I went back this time to the National Museum of Nuclear Science & History with my pinhole camera. I was testing a newly-poked pinhole; it worked ok, but I think I can get a bit more from thinner material which will cut down diffraction.
Coincidentally, I came across an interesting
link from the same time period today via the Design Observer web site illustrating some sliderule-type calculators for determining the effects of blast and radiation from nuclear weapons.
