Choosing the GEOMETRIC SHAPE of a poem

      Structural constraints often govern the patterns we find in poetry -- well-known in poetic history are rhythm-and-rhyme patterns including the sonnet and the villanelle and the limerick, and the syllable-counting pattern of some Haiku.  Because many poems were shared orally, rather than in writing, patterns of counting and sound helped to ease the challenges of remembering.

     For me a wonderful source for learning about new poetic forms is the blog of poet Marian Christie -- a writer and scholar, born in Zimbawe and now living in England , who has studied and taught both mathematics and poetry.  In her very fine blog, Poetry and Mathematics, found here, Christie explores many of the influences that mathematics can have on poetry -- including, here in a recent posting, some effects transmitted by the SHAPE of a poem.

What is not possible?

     It is impossible for a number to be greater than 2 if it is not greater than 1.  It is impossible to find a rational number whose square is 2.   Up to now it has not been possible to show that π is a normal number.  Mathematicians like the challenge of the impossible.  To challenge, to prove, to refute.
     In the poem below Chelsea Martin devises an entertaining web of circular reasoning to explore the impossibility of eating at MacDonald's.

McDonalds Is Impossible       by Chelsea Martin

Eating food from McDonald's is mathematically impossible.
Because before you can eat it, you have to order it.
And before you can order it, you have to decide what you want.
And before you can decide what you want, you have to read the menu.
And before you can read the menu, you have to be in front of the menu.
And before you can be in front of the menu, you have to wait in line.
And before you can wait in line, you have to drive to the restaurant.
And before you can drive to the restaurant, you have to get in your car.
And before you can get in your car, you have to put clothes on. 

JHM -- many math poems

     Volume 2, Issue 2 (July 2012) of the Journal of Humanistic Mathematics has recently become available online -- and it has lots of poetry.  One valuable resource has been gathered by Charlotte Henderson, a participant in the January 2012 poetry reading at JMM in Boston; Charlotte offers a report on that reading and also has prepared a folder of the poems read there, collected for our ongoing enjoyment.  In this issue also there are poems by Florin Diacu, Ursula Whitcher, and Paige S. Orland and some kind words about this blog by Gregory E. Coxson (JoAnne Growney's Poetry-With-Mathematics Blog -- An Appreciation); many thanks, Greg.
      In the wake of the BRIDGES math-art conference at Towson University last week I also want to mention the lively blog posting about BRIDGES by Justin Lanier at Math Munch.
