"And I often dream of chemistry at night, dreams that conflate the past and the present, the grid of the periodic table transformed to the grid of Manhattan. Sometimes, too, I dream of the indecipherable language of tin (a confused memory, perhaps, of its plaintive "cry"). 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."
