I guess I spend my free going back to basic thermodynamics and differential geometry concepts and being eternally confused.

But my favorite dream is of going to the opera (I am Hafnium), sharing a box at the Met with the other heavy transition metals—my old and valued friends—Tantalum, Rhenium, Osmium, Iridium, Platinum, Gold, and Tungsten.
