A thousand Christmas trees

My email poem-a-day today from www.poets.org is "Christmas Trees" by Robert Frost (1874-1963); this 1916 poem includes some calculations and reflections based on the line:

       “A thousand trees would come to thirty dollars.”

Frost's poem has provoked me to thoughts of inflation and conservation; for the full poem, follow the link given with the title above.  And, if your time permits, go back to previous "Christmas" postings in this blog at these links:  23 December 2013,  24 December 2012,  21 December 2012,  22 December 2011, and 2 September 2010.

Writing mathy poems - a student activity

On the web-page of mathematician-poet Sarah Glaz I found a link to this file of math-related poems that she prompted students to write when she visited an Arcadia University class session of "Truth and Beauty:  A Course in Mathematics and Literature" taught by mathematician-poet Marion Cohen.  The writing was prompted by an activity-list developed by mathematician-poet Carol Dorf.  Poems by Whitney Boeckel and Olivia Lantz particularly caught my eye and, with their permission, I present them here:

Amounting to Something

From the Fall/Winter 2013 issue of Poet Lore, a poem by David Wagoner about the arithmetic of expectations:

     Amounting to Something     by David Wagoner

     You were supposed to do that
     by saving yourself up
               like coins in a pig rescued
               just in time sometimes
     from in front of the candy counter  
     or the desk in the corridor

Averaging . . . geometry of the center

Perhaps partly due to his experience as an Air Force pilot during World War II,  Harold Nemerov (1920 - 1991) uses geometry with deft precision as he describes phenomena around him.  Here is a poem inspired by a 1986 news item.

The population center of the USA
Has shifted to Potosi, in Missouri.

The calculation employed by authorities
In arriving at this dislocation assumes

That the country is a geometric plane,
Perfectly flat, and that every citizen,

Related rates -- in fiction and poetry

     During the Memorial Day weekend I had the opportunity to read Black Rice (WSI, 2013), a novella by Burmese-American poet, artist, activist -- and friend -- Kyi May Kaung; I strongly recommend this book to you.  (My 5-star review of Kaung's book is available here at amazon.com -- follow the link and scroll down.)
     Here, in this blog, we mention topics if and only if they relate to both mathematics and poetry.  Read on and you will see!
     Midway through Black Rice, the narrator (speaking of an overflowing stream) reveals a negative attitude toward mathematics -- a strategy often used to provoke readers to experience empathy:  "Ahhh, just like me."  Here are the Burmese soldier's words:

Natural numbers

     My just-previous posting tells of a Monday poetry reading I was able to attend.  On Monday, May 14, a poetry reading took place that I wanted to attend but missed; poet Gary Snyder read at the Folger Shakespeare Library. 
     Written in the 1950s and read by him here on YouTube, Gary Snyder's poem, "Hay for the Horses," involves a mathematical calculation: 

A mathematical woman

As in an earlier posting (20 December 2011), today's feature includes verse by Lord Byron (1788-1824). This time the source is Byron's satiric poem Don Juan. In Canto I, the poet describes Don Juan's mother, Donna Inez, as learned and "mathematical." Here are several stanzas about her -- sagely seasoned with words like "theorem," "proof," and "calculation."

How much for a digit of PI?

Scottish poet Brian McCabe writes playfully of numbers.  In the following poem he imagines an auction of the digits of π.

   Three Point One Four One Five Nine Two
   Six Five Three Five Eight Nine Seven Nine
   Three  Two Three Eight Four Six Two Six
       Four Three Three Eight Three Two
         Seven Nine Five Zero Two Eight             by Brian McCabe 

Forgetful Number

A lovely poem about more than a number . . .

    Forgetful Number  by Vasko Popa

    Once upon a time there was a number
    Pure and round like the sun
    But lonely very lonely

    It started to calculate by itself 

Rather like an elephant

What is mathematics?
          These days I am outside of mathematics looking in and my views of the subject are more complex than during the days when I was a professor and mathematician. Back in my math-prof days -- when I moaned about those who held the view that mathematics is merely computation -- I tried to explain to uncompreheding friends the role of calculation within mathematics with this analogy:  computation is to mathematics as spelling is to poetry.  But those for whom computation is all of their mathematics do not accept this argument.  Indeed, I myself now have the notion that one can navigate life competently without algebra -- much as I get along without Spanish or Chinese. But I regret not knowing them -- they are, like algebra, among the world's important languages.

More of Pi in Poetry

Recording artist Kate Bush has written a song entitled “Pi” which includes some of π's digits in the lyrics. Likewise, Polish Nobelist (1996) Wislawa Szymborska also features its digits in her poem, “Pi,” which begins:

Poems with Fibonacci number patterns

In 21st century poetry, there are a variety of non-rhyming forms--and several of them have derived from the Fibonacci numbers.*  The Danish poet, Inger Christensen (1935-2009), wrote a book-length poem, alphabet (New Directions, 2000) in which the numbers of lines in stanzas followed the sequence of Fibonacci numbers.  "Fibonacci," shown below, by Judith Baumel is a shorter example of this form.
