      @StephenUCS It's wrong - about 1kg of Pu fissioned http://blog.nuclearsecrecy.com/2013/12/23/kilotons-per-kilogram/@WilliamJBroad …

      @russianforces I posted it b/c it was so shocking, but can't testify to it. But the link you posted doesn't work for me. @wellerstein?

      @StephenUCS @russianforces The "weight of a 1 dollar bill" is the amount of mass converted to energy, not the amount of actual Pu fissioned.

      @wellerstein @StephenUCS That's a good way of thinking about it. The way it was said in the article is rather misleading

      @russianforces @StephenUCS I think the last part of the paragraph in question is an editing mistake.

      @russianforces @StephenUCS Which is a more concrete mental model and doesn't get us stuck on hard questions like "what is binding energy?"

      @wellerstein I don't go into "binding energy" Fission releases energy, mostly as kinetic energy of fission products

      @wellerstein Where this energy comes from is a separate issue. If you mix them you get the dollar bill

      @russianforces That is, it doesn't tell you as much about nuclear weapons (why and how they work) as pop culture would have one believe.
