Miroslav Holub -- "what use is it?"

     In earlier postings I have expressed my admiration for the Czech poet Miroslav Holub (1923-1998)  -- a research scientist who also wrote fine poetry.  In a biographical sketch of Holub at poetryfoundation.org, the poet is quoted as saying, " . . . I'm afraid that, if I had all the time in the world to write my poems, I would write nothing at all."   There is no agreed standard for the amount of time  to spend on a creative work.  Many poets devote their full time to their craft;  others fear over-writing and strictly limit their writing and editing.  In each aspect of our lives it is possible to do too much or too little thinking about things.  And so it goes.
      My post on 5 April 2013 linked to several math-related Holub poems.  And here is another; in "Magnetism," Holub focuses on the sometimes-silly, sometimes-practical, sometimes-too-limiting question often put to mathematics or science, "what use is it?"
