I prove a theorem and the house expands:
the windows jerk free to hover near the ceiling,
the ceiling floats away with a sigh.
As the walls clear themselves of everything
but transparency, the scent of carnations
leaves with them. I am out in the open
and above the windows have hinged into butterflies,
sunlight glinting where they’ve intersected.
They are going to some point true and unproven.
Addition: You probably can’t explain a math problem or the deductive logic of a good proof, but you can make a good poem; perhaps the two shall never meet.
