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.
