A perfect way for math-poetry fans to celebrate Valentine's Day is to visit the anthology, Strange Attractors: Poems of Love and Mathematics (AK Peters/CRC Pres, 2008), edited by Sarah Glaz and me. Here is a sample from that collection, a limerick;
There Was a Young Maiden by Bob Kurosaka*
There was a young maiden named Lizt
Whose mouth had a funny half-twist.
She'd turned both her lips
Into Mobius strips . . .
'Til she's kissed you, you haven't been kissed!
*Of Japanese heritage, Kurosaka was born in Lake George, NW -- he became a college teacher and author of science fiction and limericks.
