When Andy was a student, his advisor Roman Jackiw would insist that Andy and others had to convert everything to a harmonic oscillator. And you know, field theory showed that this thing can be done to all elementary particles (and also to the Hydrogen atom and other things!). Andy is now what Roman used to be, and he insists that the students transform everything to a black hole. :-)
