Complement and Compliment -- and Geometry

     Poetry's special effects often come from the multiple meanings of terms used -- and today I offer  a snip of a mathy item that I enjoyed and that  plays with meaning -- an item I found a few days ago (September 19) on X (Twitter), 

A posting by California math teacher Howie Hua

And, looking back for geometry in earlier postings, here is a link to a prose poem posted in February, 2017 -- "The Geometry of Poetry" by Janet R. Kirchenheimer.   Still another geometry reading opportunity is the baseball poem "Our Ballpark" by Le Hinton (sampled in this 2015 posting).

Black boys at the blackboard doing math . . .

     Last Wednesday evening the WordWorks-sponsored poetry reading, "Poets vs the Pandemic," brought back to my attention Pennsylvania poet Le Hinton who read from his recent collection, Sing Silence, and also some newer work.  Here is Hinton's very special poem about kids learning math.

     Uses of Cotton (Eraser)      by Le Hinton
 
      When my brother tells the story,
      he forgets to mention the sock, black
      and worn. Mom darned it in three places;
      Dad used it as an eraser.
 
      I never leave out the part
      about his teaching
      us numbers. When to add.
      How to subtract.
 
      He set up a blackboard in the back-
      yard and wrote problems on it. Even invited
      the neighborhood kids. We earned a piece
      of candy for each one we got right.      

Solving for X, Searching for LIFE

     In January of this year I had the pleasure of attending a poetry reading featuring Linda Pastan and Le Hinton -- Linda Pastan's mathy poem "Algebra" is posted here and a blog SEARCH using her name can find other gems.  Pennsylvania poet Le Hinton's poem, "Baseball," appears in a 2015 posting at this link and below I offer his "Solving for X."

Solving for X     by Le Hinton

Because your father was a teacher,
he set up a blackboard to teach you math.

You were four, almost five, learning the difference
between more and less.  How to add.  When to subtract.  How
to savor a piece of candy when you got an answer exactly right.

Geometry of baseball

Many poems are written of baseball; a few of them involve mathematics --  see the posting for April 9, 2010 for math-related baseball poems by Marianne Moore (1877-1972) and Jerry Wemple; see the posting for September 18, 2011 for one by Jonathan Holden.
     Today I feature the opening stanza from a baseball poem by Pennsylvania poet, Le Hinton.

from   Our Ballpark    by Le Hinton

       This is the place where my father educated us:
       an open-air school of tutelage and transformation.
       This is where we first learned
       to count to three, then later to calculate the angle
       of a line drive bouncing off the left field wall.
       We studied the geometry and appreciated the ballet
       of third to second to first, a triple play.
