Very funny graphic borrowed from Cosmic Variance:
So we live in a world where an entire state of matter is considered a national security risk. What I want to know is if Homeland security has considered the implications of the critical point. Everyone knows that gases are terrorist sympathizers, and given a high enough temperature and pressure, it’s impossible to tell your gaseous friends from the evil liquid masterminds.
And are they keeping an eye on Ices II through XII? They’ve always seemed shifty to me. (I’d have to say that Ice-i’ is the most dangerous part of the phase diagram of all…)
