Win saw that the theory that Newton'd invented


By Einstein's discov'ries had been badly dented.


What now? wailed his colleagues. Said Erwin, "Don't panic,


No grease monkey I, but a quantum mechanic.


Consider electrons. Now, these teeny articles


Are sometimes like waves, and then sometimes like particles.


If that's not confusing, the nuclear dance


Of electrons and suchlike is governed by chance!


No sweat, though--my theory permits us to judge


Where some of 'em is and the rest of 'em was."


Not everyone bought this. It threatened to wreck


The comforting linkage of cause and effect.


E'en Einstein had doubts, and so Schroedinger tried


To tell him what quantum mechanics implied.


Said Win to Al, "Brother, suppose we've a cat,


And inside a tube we have put that cat at--


Along with a solitaire deck and some Fritos,


A bottle of Night Train, a couple mosquitoes


(Or something else rhyming) and, oh, if you got 'em,


One vial prussic acid, one decaying ottom
