Mathematical structure and Multiple choice

     A sonnet repeats the iambic rhythm of the heart beat (da-DUM, da-DUM, . . .) with a line length corresponding to a typical breath (5 heartbeats); it thus seems easy to internalize the numerical structure that guides such a poem. 
     A decision tree offers a very different choice of mathematical structure for a poem -- displaying for a reader different choices among stanzas.  Originally proposed to the OULIPO by founder Francois Le Lionnais, and referred to as a multiple-choice narrative, such a structure allows readers of a poem to choose among subsequent events. Instead of reading the poem vertically, we may jump about, choosing the sequence we want to read.

Poetry in a math text

     In the 1980s, all students at Bloomsburg University were required to take at least one mathematics course and I worked with colleagues to develop a suitable offering -- one that did not require expertise in algebra but which emphasized problem-solving.  Our course became "Mathematical Thinking" -- and I began to develop suitable materials -- eventually writing and publishing Mathematics in Daily Life:  Making Decisions and Solving Problems (McGraw-Hill, 1986).  Each of the twenty-two chapters of this textbook is introduced with a relevant quote.  Chapter 11, "Visualizing the Structure of Information with a Tree Diagram," opens with two lines by one of my favorite poets, Theodore Roethke:

               Once upon a tree              
               I came across a time.

Statistics feels like poetry

    Today's title comes from the following poem by statistician and poet Eveline Pye (introduced to this blog on 18 October, 2011).

   Numerical Landscape      by Eveline Pye

   Like a tracker, I smell the earth
   on my fingers, listen for the slightest
   echo as I stare out at a world
   where bell-shaped curves loom
