Midrange seismograph

The Citizen Array Network is a pretty cool idea: a distributed network to monitor for nuclear weapons tests and other science. I got this presentation from the live-tweeting of the CTBTO Conference going on this week. The URL http://citizenarray.net redirects to it. So I don’t know how far along it is; I’d guess not very. I’ll keep an eye on it and report if anything new turns up. The photo is of a home seismograph now under development, from this presentation.

As I’ve written, “breakout time” in regard to Iran’s nuclear capabilities is a poor measurement. Unfortunately, it’s useful in negotiations to have a reference number of some sort, so it was hard to resist. Here’s one way I was concerned it could be misused: switch around a few assumptions, and presto, you’ve got a “proof” that the Iran deal is a bad one. ¬†Fortunately, Kelsey Davenport and Daryl Kimball show what’s wrong with that proof.

Interview with Timothy Snyder about Russia’s view of history. Snyder is one of the best commentators on the situation in Ukraine and Russia today. Read everything he writes. There are also some videos of his talks available.

The evolution of anti-Americanism in Russia. The author is at the Levada Center in Russia, the most reliable polling center in the country. His analysis is somewhat different from what I, an American, would expect. Such differences are important in understanding what’s going on with Russia.

Would Pakistan sell Saudi Arabia nuclear weapons? Probably not, but their relationship is complicated.

At the same conference where Tim Hunt was making an ass of himself, the Association of British Science Writers released a report on Sexism in Science Journalism.

Another woman scientist you’ve never heard of: Melba Phillips

How tritium illumination devices (like exit signs) work.

For those who have made it all the way to the end, Navy Cats!
