Mathematics works with witchcraft

T. A. Noonan sometimes uses the languages of mathematics and computer science as tools in her experimental poetry, gathered in her collection The Bone Folders (Sundress Publications, 2011).  These poems examine -- at times with mathematical vocabularies and notations -- the complexities of love and loss in the regime change in a coven of Louisiana witches.  Here, for example, is Noonan's opening poem, "Difference Engine."
