Shaping sentences with Fibonacci numbers . . .

Counting words . . ..  

     1                One
     1               person
     2               with courage
     3               makes a majority.               Andrew Jackson (updated)

Counting syllables . . .

     1               Life
     1               is
     2               painting
     3               a picture
     5               not doing a sum.                    Oliver Wendell Holmes, Jr.

Prove It

After observing that

               1  =  1
and         1 + 3  =  4
and         1 + 3 + 5  =  9
and         1 + 3 + 5 + 7  =  16
and         1 + 3 + 5 + 7 + 9  =  25

it seems easy to conclude that, for any positive integer n, the sum of the first n odd integers is n2.

Of all geometries, feathery is best . . .

The title for this post comes from Twinzilla (The Word Works, 2014), by Charleston poet Barbara Hagerty.  The title character of this collection is one of several poetic personalities that inhabit Hagerty's verse, and she offers a playful view of life's dualities -- sometimes versed in mathematical terminology.  Here's a sample.  

     Twinzilla Cautions *     by Barbara G. S. Hagerty

     Do not accept packages from unknown persons.
     Beware non-native strangers who may be concealing
     hazardous contraband "down there."
     Question algebra.  Dismantle thoughts traveling
     the brain's baggage carousel in parabolas.

Measuring the World . . .

     Yesterday afternoon, at the Goethe Institut in Washington DC, I saw a wonderful film, "Measuring the World." Based on a popular 2005 novel by Daniel Kehlmann, the story of a friendship between preeminent German mathematician Carl Friedrich Gauss (1777-1855) and Prussian naturalist Alexander von Humboldt (1769-1859).  The film offers a delightful interplay of personalities and ideas as it darts between the explorations of these two men -- one digging inside his head for mathematics and the other traveling over mountains, through jungles, across oceans.

Emily Dickinson

     Although I do not consider any of Emily Dickinson's poems "mathematical," I find that she does not shy from using the terminology of mathematics. For example, her repetition of the word "circumference" noted in an earlier posting.  (To search this blog for mentions of Dickinson (1830 - 1886) or any other poet or topic, follow the instructions offered in green in the column to the right.)
     Dickinson is on my mind these recent days following my opportunity last Saturday evening to attend a session of a conference held by the Emily Dickinson International Society.  A gracious invitation by Martha Nell Smith enabled me to attend a program that featured two long-time friends, actor Laurie McCants of the Bloomsburg Theatre Ensemble, performing a scene from her one-woman show, Industrious Angels, and Stephanie Strickland, a New York poet who, along with collaborator Nick Montfort, offered background and performance for Sea and Spar Between, a poetry generator that works with language patterns for these two writers.

Summing thin slices

This poem by recent (2008-2010) poet laureate Kay Ryan at first made me think of calculus, of integration, summing all the thin slices to find the area under a curve.  And then the poem moved me on.

A whole and its parts

     Aristotle may have been the first to assert that a whole is more than the sum of its parts.  Mathematics textbooks are likely to say otherwise, postulating that a whole is equal to the sum of its parts

     Emily Dickinson also comments on the matter.

                (1341)         by Emily Dickinson
 

     Unto the Whole -- how add?
     Has "All" a further realm --
     Or Utmost an Ulterior?
     Oh, Subsidy of Balm!

Which is the BEST order?

At Bartleby.com, we find  a quote from Samuel Taylor Coleridge (1772-1834) which says, in part " ... poetry—the best words in their best order." 

Consider the two orderings of the words "were" and "we." (To choose which is best is not possible until we know more of what the writer wishes to say.)

          We were!
          Were we?

Integrals -- a poem

Integrals    by Jonathan Holden

     Erect, arched in disdain,
the integrals drift from left
across white windless pages
to the right,
serene as swans.

"The Reckoning" by M. Sorescu (Romania,1936-96)

Works by poet and playwright  Marin Sorescu (1936-1996) continue to be popular with Romanian readers--and he is one of the most-frequently translated of Romanian poets.  In "The Reckoning" we see and hear his irony twisting among images chosen from mathematics.

Mathematics in poetry by Nichita Stanescu

     Though formerly a math professor, my recent teaching has involved poetry--and I have been fortunate to spend several summer months at Scoala Andrei Muresanu in Deva, Romania, teaching poetry and conversational English.

Jordie Albiston -- structure behind the writing

       I love sonnets and the one below by Jordie Albiston is a favorite of mine.
     Albiston is an Australian poet with a sense of orchestration learned from music.  Her collection, The Sonnet According to 'M' recently won the New South Wales literary award.  In her words:

Glances at Infinity

Counter-intuitive notions are among my favorite parts of mathematics and, in considerations of infinity, these are numerous.  Recalling Zeno's paradox, we capture the infinite finitely in this summation:

     1 + 1/2 + 1/4 + 1/23 + . . . + 1/2n +   . . .    =  1
