Choosing what words mean . . .

     Nineteenth century writer and mathematician Lewis Carroll (1832-1898) gave his character, Humpty Dumpty, these words:  "When I use a word, it means just what I choose it to mean -- neither more nor less."  And so it is in mathematics -- where, for example, the term "rational" (used in the poem"The Disposition of Art," shown below) has a precise meaning that differs from its typical conversational usage.
     The photo below shows computer-generated art by Silver Spring artist Allen Hirsh -- and, beside it, a framed version of the poem mentioned above.  Our work was exhibited together at last summer's BRIDGES and MAA conferences.  A clearer presentation of Hirsh's art -- "An Outgrabed Mome Rath" -- is available here.  My poem is presented below, beneath the photo.
