Michael Swanwick's Periodic Table of Science Fiction 59 Pr Praseodymium 140.9077 Absolute Zero &quotraseodymium, when alloyed with nickel to form PrNi5, responds to being magnetized by getting colder. This property has made it possible for us to come within a thousandth of a degree of absolute zero," the physicist said. "Cool!" her daughter replied. It was take-your-child-to-work day, and she'd never seen the lab before. "I'm going to pretend you didn't say that." The physicist tapped a machine that looked like the mother of all death rays. "This is the magnetic resonance focusing unit. It directs five-point- three teratogauss of magnetic force on that tiny little speck of praseodymium there." "Neat-o! How much is a teratogauss?" "It's?don't touch that! You're fine where you are, but if you actually touched the cold spot, it would suck all the heat out of you in a nanosecond. You'd shatter like ice. That's what happened to Gregor." "How awful!" "Well ? he was only a grad student. Still, the paperwork to get a replacement was hideous." "Hey, look at this?you don't have the power on this thing set to maximum. What happens when you crank it all the way up?" "Theoretically, it would
