Truman never ordered the use of the atomic bombs—but he did order atomic bombings to be stopped On the 80th anniversaries of the Hiroshima and Nagasaki bombings, President Truman deserves credit for the first use of the atomic bomb in war. But he also deserves some credit for the fact that atomi...

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.

Sections 13.12 and 13.13 of the Los Alamos – Technical volume of the Manhattan District history were totally DELETED when released in 2013/2014 by the Department of Energy.

However, I found an un-redacted version at the National Archives in the files of the Joint Committee on Atomic Energy, and was able to re-insert it into the original document. These sections are about energy loss in thermonuclear processes.

Over the last decade or so I have occasionally been able to restore redacted pieces of the Manhattan District History, esp. the Los Alamos – Technical volume, as I found excerpts in other misc. places. I've recently updated the copy of it that I put up at Archive.org: archive.org/details/Manh...

Even the optimization manual hasn't been updated yet :(
Anyway, for what is worth, I'm always interested in new microarchs

I realized recently that a number of the descriptions of the target selection for the atomic bombings get the progression a bit wrong. What follows is what I think is the most complete timeline of changes to the target list through the atomic bombings themselves that is available. (1/...)

The deal seems to be that people can largely live like in pre-pandemic times as long as we accept getting miserably ill maybe twice a year (especially during family holidays), accept heightened risks of long-term health problems, and let old/vulnerable folks die. Doesn’t seem like a good deal to me.
