And let me add a bit of mathematics -- for my friends (both gay and straight) who love to play with language:
           A recent New Yorker article  ("Go Ask Alice" by Anthony Lane, 6-8-15,48-54) 
          on Lewis Carroll (1832-1898) offered this quote -- this "found" poem:

            Obtuse anger
            is that which is greater
            than right anger.

This year, 2015, marks the 150th anniversary of the publication of the first edition of Alice's Adventures in Wonderland.

Personal geometry

We have recently passed the first anniversary of the death (6 May 2010) of Elena Shvarts, one of Russia's finest contemporary poets. Here is her "Poetica -- More Geometrico" (translated into English by Thomas Epstein).

Voices in a Geometry Classroom

I have been invited to return next week (October 20 at 7 PM) to Bloomsburg University, where I taught mathematics for lots of years, for a poetry reading.  Preparation for the reading (which celebrates my new book, Red Has No Reason) drew my thinking back to my teaching days at Bloom and to "Geometry Demonstration," a poem about the arguments in my head as I faced a particularly challenging class of geometry students.  Here it is.
