US National Archives and Records Administration Try as I might, I'm not perfect. My goal is to get every detail in every story right, but sometimes a post gets through with a factual error. Such was the case last night, in a story about Russia's new floating nuclear power plant. Some background research led me to believe that it was the first of its kind. A couple of Ars readers, thankfully, disabused me of that notion quickly (one cool thing about writing for Ars is you always know that you're writing for a bunch of people who are dramatically smarter than yourself).
