JF Ptak Science Books Quick Post
I've written perhaps 100 posts for the History of Fission and Nuclear Weapons series on this blog, and in that I've collected a number of (pre-1960) images showing a nuclear explosion over specific, recognizable U.S. cities. Some of these came as a result of Cold War propaganda, others were used to show the effects of the bomb on a familiar profile. I've not put them together in one post before, so I thought to do it now. (The very first image of any sort of nuclear weapon published in the popular press showing its effects on a U.S. city appears in PM newspaper, 7 August 1945--as I've said before, I have no idea how these folks put together such a comprehensive issue in the day+ after the Hiroshima bombing, but they did).
Here are the U.S. cities I've collected so far--the majority of them are New York City, mainly because it has the most recognizable features making it easier for a broad spectrum of readers to understand the destructive force of the bomb(s).
