Loving the difference quotient ... and more ...

     From Philadelphia poet-mathematician, Marion Cohen, a new collection  -- Closer to Dying (Word Tech, 2016).  When I received the book a few days ago and began to read I did, of course, seek out mathy poems.  Two of these are included below. In this first poem Cohen has some fun with the terms and symbols of introductory calculus.  In the second, she tells of an encounter of the sort that happens to many mathematicians  -- meeting someone who supposes that mathematicians do what calculators do. (This link leads to a collection of mathy poems (including ones by Cohen) at talkingwriting,com.)

Before calculators we did more counting!

One of many sources of good poetry online is American Life in Poetry, collected by former U S Poet Laureate Ted Kooser.  In Column 368, Kooser offers "Numbers" by New Jersey poet, Jared Harel (first published Fall 2010 in The Cold Mountain Review).  Kooser's introduction notes, "My mother kept a handwritten record of every cent she spent from the day she and my father were married until the day she died. So it’s no wonder I especially like this poem  . . . "
