The Mobius Strip -- in a LIMERICK

     Mathematics offers brief, condensed language for many big ideas.  Even for small problems -- such as the word problems of a beginning algebra class -- translation of the words into a mathematical equation offers the chance to express the problem precisely and to solve it using established procedures.    

     And brief mathematical forms also are popular in poetry -- the six-line Fib and the five-line rhyming stanza called a limerick both have wide appeal.  And, because of the brevity, the language must be concise.  At this webpage, maintained by Joachim Verhagen, are lots and lots of mathy limericks.  Here is a sample:

          The Moebius strip is a pain,
          When you cut it again and again,
               But if you should wedge
              A large disk round the edge
          Then you just get a PROjective plane.

This link leads to an interesting article about a Mobius strip made of light (see also the photo below); this link leads to a Wikipedia article about a real projective plane.  And more of Verhagen's Mobius strip limericks may be found here.

Moebius Strip

Following a lead from Francisco, I found (here) this tiny poem by Michael Hessel-Mial:

       moebius strip

       a belt of clouds
       twist it, latch it
       twisted

       which way will it rain?

A poem for a math-friend

     On July 14, 2012, my good friend, Toni Carroll, passed on. I first knew Toni in the 1980s as a colleague in the department of mathematical sciences at Bloomsburg University.  Her warmth and inclusiveness drew many people to her and I was one of these.  In my view she also was fearless.  While I continued to contemplate action, she moved quickly toward righting an injustice.  I have learned from her to be a bit more brave.  

Half-twist and link -- in a Sestina

     Mobius strip       by Heidi Willamson

     A simple science trick to try at home.
     Half-twist a slip of paper. Link the ends
     to make an ‘O’. Take a pencil, trace a line that loops
     the shape formed by the surface. See
     how the in and out sides merge. The join
     tangles dimensions. There’s no front or back.
