Mathematics of Family -- in a Poem

     Split This Rock is an activist poetry organization that calls poets to a greater role in public life and reaches out to a network of socially engaged poets; the organization is  centered in Washington, DC but reaches all over the world . . .   One of their ongoing activities is the selection of a Poem of the Week -- and one of their recent choices was a challenging and fascinating poem that included frequent uses of mathematical notation to express its ideas.
