Stories of Quadrilaterals

     Sometimes I have time to browse my shelves and rediscover old favorites.  Several of this blog's much-read poems have come from Scottish author Brian McCabe (Find blog search results at this link) -- and below I offer the first part of McCabe's two-part poem ("Two Quadrilaterals") entitled "The Restless Square."

Two Quadrilaterals    by Brian McCabe

     Part 1.  The Restless Square  

          There was a square who yearned
          to become something else.

          It stretched its legs to mimic
          an elegant rectangle but
          lost its balance, leaned over
          in a perilous parallelogram.    

Poems starring mathematicians

      One of the challenges posed by a multi-year blog is locating interesting old posts.  One of  my frequent early topics was "poems starring mathematicians" and I offer links to several of these from 2011 below:
     December 8 "Monsieur Probability" by Brian McCabe
     November 13  My abecedarian poems, "I Know a Mathematician" and "Mathematician" 
     July 5  "Fixed Points" by Susan Case -- about mathematicians in Poland during WWII
     July 2  "To Myself" by Abba Kovner
     January 30  "Mr Glusenkamp," a sonnet to a geometry teacher by Ronald Wallace
     January 28  "Mathematician" by Sherman K Stein

     And, here is a link, via PoemHunter.com to "The Mathematician in Love," a poem by William John Macquorn Rankine, a poem that appears also in the multi-variable  anthology, Strange Attractors:  Poems of Love and Mathematics (AK Peters, 2008), edited by Sarah Glaz and me.  Here is the first (of 8) stanza of Rankine's entertaining poem:

          A mathematician fell madly in love
          With a lady, young, handsome, and charming:
          By angles and ratios harmonic he strove
          Her curves and proportions all faultless to prove.
          As he scrawled hieroglyphics alarming.

Number personalities

In his collection, Zero, Scottish poet Brian McCabe raises questions about numerical classifications.  He begins "The Fifth Season" with "Everyone talks of the four / -- none speak of the fifth." Another poem, "The Seventh Sense, " moves from a similar beginning " . . . none speak of the seventh" into a dreamy apprehension of the magical possibilities of items not yet classified. The following selection from Zero, "Triskaidekaphobia," offers remedies for the fear of bad luck brought by 13. 

Sophie Germain dressed as a man to study math

One of the fine sources for biographies and other topics in the history of mathematics is MacTutor History of Mathematics archive, hosted by the University of St Andrews in Scotland.  Poet Brian McCabe cites this archive for historical information he used as background for his poems starring mathematicians -- found in his collection, Zero (Polygon, 2009).  Here is McCabe's poem for the outstanding French mathematician, Sophie Germain (1776-1831). 

Monsieur Probabilty

In recent months, I have encountered a variety of poems about mathematicians (Links to several of these are provided at the end of this post.) and one of the sources is Scottish poet Brian McCabe's  collection Zero (Polygon, 2009).    It is said that life imitates art -- and this is vividly demonstrated by the art of mathematics as lived by Abraham de Moivre (1667-1754).  Here is McCabe's poem. 

How much for a digit of PI?

Scottish poet Brian McCabe writes playfully of numbers.  In the following poem he imagines an auction of the digits of π.

   Three Point One Four One Five Nine Two
   Six Five Three Five Eight Nine Seven Nine
   Three  Two Three Eight Four Six Two Six
       Four Three Three Eight Three Two
         Seven Nine Five Zero Two Eight             by Brian McCabe 

Division by zero

The November 2011 issue of the Scottish ezine, The Bottle Imp, is just out and it includes my review of poet Brian McCabe's Zero (Polygon, 2009). To stir your interest, I include a few lines from McCabe's title poem (which chronicles the irregular history of zero) -- and then offer a human interpretation of division by zero in a poem by Ann McNeal.
