Hello! I have written a short article about the atomic bombings, and the anniversary that I think gets overlooked — when Truman *stopped* further atomic bombing, and why he did so. thebulletin.org/2025/08/trum...

For this 80th anniversary of the Trinity test, I was able to get a much higher-resolution version of the map that was created of the test's fallout contours, on July 21, 1945.
