Time and Again, based on a story by H. Beam Piper, first broadcast over NBC radio as an episode in the series Dimension X on July 12, 1951. The story originally appeared in the April, 1947, issue of Astounding Science Fiction. This was Piper's first published story.
This story interests me not just for its thought experiment aspect but because it evokes the last days of the Pacific War as it was for people at home in the states, how they thought about the war, and in particular what it was like the day the atomic bomb was dropped on Japan, and more broadly how the future was expected to play out in another generation -- not well. Not well at all.
