This feature is experimental and meant to make it easier to browse past posts. If it blows up or fails in some way, let me know. Not all old posts have brief descriptions as of this writing, but eventually I will fill them all in.

17The K-25 gaseous diffusion plant: the single largest and most expensive Manhattan Project site.
Meditations
Of the $2 billion spent on the Manhattan Project, where did it go, and what does it tell us about how we should talk about the history of the bomb?
 2A copy of the final "atomic bomb" leaflet, I think? I don't read Japanese, but this was attached to the above memo. If you do read Japanese, I'd love a translation...
Redactions
A brief update to the last post: translations of leaflets dropped on the Japanese after Hiroshima.
April 2013
26Leaflet 151-J-1: "Earthquake from the sky."
Redactions
Did the United States warn Japan about the atomic bombs prior to their use? A mystery is unravelled.
12From Hans Bethe's "Memorandum on the History of the Thermonuclear Program" (1952), which features some really provocative DELETED stamps. A minimally-redacted version assembled from many differently redacted copies by Chuck Hansen is available here.
Meditations | Redactions
Blacking something out is only a step away from highlighting its importance, and the void makes us curious.

 1Aerial view of B Reactor at the Hanford Site.
Redactions | Visions
An anonymous wartime wordsmith comes up with an novel interpretation of why Hanford was so secretive, and so unpleasant to work in.
February 2013
25Shot HARRY (HAMLET) of Operation Upshot-Knothole.
Redactions
A poem and song, both classified "secret," shed light on the early days of continental nuclear testing.
19Still from a Sandia supercomputer simulation from 2007 of the 1908 Tunguska event, showing the blast wave formation as the meteor detonates above the ground. Intense! But not a nuke. Source.
Meditations
Why I get annoyed when we talk about meteors, earthquakes, and tsunamis in terms of megatonnage.
 8NUKEMAP at 10 million
News and Notes | Visions
Some data from a year of NUKEMAP, and a promise of new things to come...

"A good deal has been written about Hiroshima, but no-one can describe adequately the smell — and the flies."
January 2013

Meditations | News and Notes
Three recent losses — two people, one building — highlight that the living presence of the Manhattan Project is rapidly vanishing.
22H-bomb history drawing, by George Gamow
Visions
The U.K. Atomic Energy Authority's bizarre coat of arms, and more H-bomb drawings from George Gamow.
18George Gamow, laughing and smoking, probably ca. the 1950s. Photo from the AIP Emilio Segrè Visual Archives.

The colorful physicist's postwar concerns about the teaching of nuclear physics, and an H-bomb doodle.

Children and existential fear, from the high Cold War to Stockton, California, from Stockton to Newtown, Connecticut.
14"This is the Mrs. Behind the Missile" -- AC recruitment ad, 1958
Visions
How does one recruit nuclear weapons designers? In the 1950s, you could just take out ads in popular magazines.
 7Yes, I know that this is not really a Mayan calendar. Cut me some slack. The Doomsday Clock is a registered trademark of the Bulletin of the Atomic Scientists, used here only in jest.
Meditations | News and Notes
Are we closer to Doomsday than we were last year? Plus, some pretty things to distract you from all that gloomy thinking.
November 2012

The US government doesn't like to draw atomic bombs, but the Russians don't mind drawing American nukes.
15Nuclear lightning
Redactions
What would make a nuclear bomb attack even worse? How about a nuclear attack that generates its own thunderstorm?
 7The grooviest Edward Teller graphic, ever? I bought this on eBay, if you can believe it. An AP photo from July 1959: "Dr. Edward Teller, who played a leading role in the development of both the atom and hydrogen bombs, feels that Russia will be the unquestioned leader in the scientific field in 10 years. He believes that it is inevitable that Russia should take the lead because educating a scientist is a long process and the Soviets currently are training more scientists than the United States. This photo-drawing by AP Newsfeatures artist Dick Hodgins Jr. symbolizes Dr. Teller's work with the atom and also his many controversies with Congress."
Meditations | Visions
Reflections on a year of nuclear secrecy blogging. Plus some neat images.
 2October 5, 1962: CIA chart, "Reconnaissance Objectives in Cuba." We're still looking, in a way. Via the National Security Archive.
Meditations
Are there new things to be said about the Cuban Missile Crisis after 50 years of talking about it?
October 2012
25Range of the missiles that the Soviets were installing in Cuba. A number of working MRBMs (Medium Range Ballistic Missiles) had already been installed.
Meditations
Contrary to popular perception, Kennedy's "quarantine" of Cuba during the Missile Crisis wasn't a complete success — there were already lots of nukes there.
