What can 7 objects say? Or 100?

     A friend, a high school art teacher, had one of her students paint a portrait of her -- not of her bodily self but a still life of the seven possessions that she felt best defined her.  Since that time, more than seven years ago, I have been trying to decide what my seven objects would be.  How might I portray me?    
     An article in today's NY Times, "Stuff that Defines Us," reminded me that I have neglected that project.  The article tells of the British Museum's ambitious and fascinating project to choose 100 objects from their collection to summarize the history of the world.

Chaos Over the Hors d'Oeuvres

Some systems of equations can produce vast changes in output with only small changes in input.  Or not.  This sensitivitiy to initial conditions is a key characteristic of chaos.  As happens not infrequently in mathematics, the term chaos also carries larger-world meanings additional to the correct ones -- indeed, the phenomena studied in chaos theory are not haphazardly disordered but are complex.  Very very complex.  Judy Neri's poem addresses this topic. 

Permutations and Centos

A Cento is a collage poem made of lines taken from other poems -- such as a sonnet composed of lines from fourteen of Millay's sonnets, or Shakespeare's -- or from newspaper articles or television advertisements or whatever. Here's a three-line sample from a Cento, "Patchwork," composed by Joanna Migdal to celebrate women poets.

   I dwell in Possibility.                                              (Emily Dickinson, #657)
   Yes, for that most of all.                                        (Denise Levertov, “The Secret”)
   It’s four in the afternoon. Time still for a poem.   
                                                                        (Phyllis McGinley, “Public Journal”) 

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! 

Things the fingers know

Blogger Peter Cameron sent me a link to an lively article, "Eveline Pye: Poetry in Numbers"  in the September 2011 issue of the statistics magazine, Significance.  Written by Julian Champkin, the article tells of Eveline Pye -- lively and interesting Glasgow statistician, teacher, and poet -- and includes a selection of her work. One of the poems offered therein is "Solving Problems."

Hamilton -- mathematician, poet, Irishman

     October 15-22 is Maths Week in Ireland -- as I learned from this article in the Irish Times celebrating maths and the Irish mathematician Willam Rowan Hamilton (1805 - 1865).  Turns out that Hamilton's quaternions are useful in design of video games and 3D effects in the cinema.
     Hamilton -- a mathematician, astronomer, and physicist -- was also a poet; a contemporary and friend of Samuel Taylor Coleridge and William Wordsworth. His poems do not speak of mathematics -- but here is a sonnet he wrote to honor Jean Baptiste Joseph Fourier (1768 – 1830), a prominent French mathematician and physicist.

Like poetry, mathematics is beautiful

     Congratulations to Justin Southey who is completing his doctoral studies in mathematics at the University of Johannesburg under the direction of Michael Henning. Recently Justin contacted me to ask permission to include one of my poems in the introduction to his dissertation, "Domination Results:  Vertex Partitions and Edge Weight Functions."  Here is a portion of Justin's request: 

Numbers from the Piano

     Of all of the things we might try to say when we sit down to write a poem, which are the ones we should choose?  Sometimes we may say what first occurs to us -- begin to write and keep going until we are done.  This may suffice -- or it may seem to lack care.  To be more careful, we might seek a pattern to follow:  perhaps we might form lines whose syllable-counts follow the Fibonacci numbers.   Or construct a sonnet -- fourteen lines with five heart-beats per line and some rhyme.  Or devise a scheme of our own.

Counting the women

     The stimulus for this posting appeared a few weeks ago in the Washington Post -- in an article that considers the loneliness of women in STEM fields (science, technology, engineering, math). 
     For me, it was never a conscious thing -- the counting.  It simply happened.  The numbers are small and you know, if you are a woman and a mathematician in a room full of mathematicians, how many women are in the room.  Any room.  It is a small counting number.  Sometimes it is 1. 

How I won the raffle

Dannie Abse is a deservedly celebrated Welsh poet -- and before his retirement he was also  a physician.  I first saw "How I Won the Raffle" in Poetry  in 1992 -- now it also is included in his collection Be Seated Thou (Sheep Meadow Press, 2000).

   How I Won the Raffle     by Dannie Abse

   After I won the raffle with the number

Action at a distance

One of the great things about writing this blog is the people who have -- out of the blue and across the miles -- sent along a great poem or tidbit.  One of the valuable contributors is Tim Love, a British computer guy and poet -- and also a blogger (at LitRefs). The mysterious concept of "Action at a Distance" drives this Love poem:

The square root of Everest

Of the poets who frequently use mathematical ideas in their work, Howard Nemerov (1920-1991) is one of my favorites.  Recently, while browsing at The Writer's Almanac, I found this poem.

To David, About His Education       by Howard Nemerov

Math meets Dr Seuss

Blogger Sue VanHattum (MathMamaWrites) sent me a link to a posting on another blog, kGuac, on which she found a Dr Seussical expression of the quadratic formula -- written by blogger Katie Benedetto for extra credit in her college abstract algebra class.  Here are several stanzas of Katie's poem:  

Learning to count

The childhood of Romanian poet Nichita Stanescu (1933-1983) took place during World War II and his teen years during his country's adjustment to a new Communist system; his dark images are drawn from a culture largely unknown to the outside world.  Often, however, he utilized mathematical imagery or terminology; here is his "Learning to count." 

Mathematical theorems tornadoing

This poem is fun!

   Horse’s Adventure    by Jason Bredle 

   The horse discovered a gateway to another
   dimension, and with nothing else to do, moseyed
   into it just for grins, and man, you
   don’t even want to know what happened
   next—it was just, like, Horse at the French
   Revolution. Horse in Franco’s living room.

The wealth of ambiguity

When we read these lines by Robert Burns (1759-1796),

     Oh my luv is like a red, red rose,
     That's newly sprung in June . . .
    
we don't know whether he compares a woman he loves to a flower or whether it is his own emotion he describes.  And the multiplicity of meanings is a good and pleasing thing.  Similarly, when we read the problem,

     Solve the equation, x² + 4 = 0 

Poetry at JMM -- in Boston 6-Jan-2012

Call for Submissions:
     The Journal of Humanistic Mathematics will host a reading of poetry-with-mathematics on Friday, January 6, 5-7 PM in Boston’s Hynes Convention Center at the annual Joint Mathematics Meetings. Reading organizers include JHM editors, Gizem Karaali and Mark Huber, and poetry-math blogger, JoAnne Growney.  Although the reading is open to all, without pre-selected readers, we will prepare a written program of poets who submit their work by our December 1 deadline. Both mathematician-poets and others who use mathematics in their poems are invited to submit.

Baseball, math, and poetry

The end of summer approaches and, with it, the end of the baseball season.  This blog celebrated the triplet (baseball, mathematics, poetry) on 9 April 2010, featuring samples from and links to poems by Marianne Moore and Jerry Wemple. Today we herald the same trio, this time with "Night Game" by Jonathan Holden.

Best words in the best order

     Writers of mathematics strive for clear and careful wording, especially in the formulation of definitions. Well-specified definitions can enable theorems to be proved succinctly. For example, the relation "less than" (denoted <) for the positive integers {1,2,3,...} may be defined as follows:

     If  a  and  b  are integers, then 
               a < b  if  b - a  is a positive integer. 

     Although the simple definition of "less than" as "to the left of" in the list {1,2,3,...} is intuitively clear, the formal definition above is better suited for mathematical arguments. It defines "less than" in terms of the known term, "positive." This sort of sequencing of definitions is common in mathematics -- one may go on to define "greater than" in terms of "less than," and so on.
     Saying things in the best way is also a goal of poetry. Well known to many are these words of poet Samuel Taylor Coleridge (1772–1834): 

Analysis of a sacred site

Poet Allison Hedge Coke descends from moundbuilders and mixed ancestry from several Native American communities with several Europoean ones.  Her verse play, Blood Run, is dedicated to the original citizens of the former city now named Blood Run along the Big Sioux River and to all who work to preserve sacred sites. Moreover, the entire text is mathematically encoded.   Chadwick Allen, an English professor whose interests include American Indian and New Zealand Maori literatures and cultures, has written an article for American Literature that explores the sacred numbers and thematic geometry that connects Hedge Coke's verse with the sacred site; we will offer a sample of Allen's analysis following "Snake Mound"from Blood Run: 

A Piece of Coffee -- Stein with some math terms

I love the poetry of Gertrude Stein.  Perhaps this is so because I have never taken a class in which her work was taught and I have never read it with pressure to "understand."  I enjoy reading Stein's poems aloud.  Because they keep me alert -- both eye and tongue.  Because they puzzle me. And because I sometimes see something amazing, true and almost within reach.  Here, from Tender Buttons / Objects: is "A Piece of Coffee." 

Symmetric 4 x 4 square

Martin Gardner (1914-2010) studied philosophy and was interested in everything.  For 25 years he wrote the "Mathematical Games" feature for Scientific American.  At Magic Dragon Multimedia, Jonathan Vos Post has collected many of the poems Gardner featured in his column over the years.  Here is a symmetric square poem from February, 1964.

Applying statistics . . .

From Seattle poet Kathleen Flenniken, a sensitive application of the normal distribution to the population of participants in an elementary school recorder recital:

   The Beauty of the Curve     by Kathleen Flenniken

   The curtain lifts on Bryant Elementary School's
   Spring Recorder Recital.  Ninety third-graders
   fumble with their instruments, take a breath

   and blow.  Their parents, braced, breathe too
   as "Hot Crossed Buns" emerges, a little scattershot --
   the Normal Distribution brought to life.

An Integral Limerick

This plane of earthly love

Poet Joan Mazza celebrates qualities mathematical: 

   To a Mathematician Lover     by Joan Mazza

   As we embark on this plane
   of earthly love, I should explain,
   my experiences with men
   have doubled my troubles
   and halved my pleasures,
   divided my time into fractions

Earthquake and Hurricane

It would not be easy to argue that a poem whose numbers merely identify its stanzas is "mathematical" but "Curriculum Vitae," found at poets.org and written by Pullitzer Prize winning poet Lisel Mueller, also contains the words "earthquake" and "hurricane" and thereby is significant on this Saturday in Silver Spring -- five days after a 5.8-magnitude earthquake damaged both the Washington Monument and the National Cathedral and on the very day that millions of us are watching the progress of Hurricane Irene as it storms north along the eastern coast of the US. In acknowledgment of these days, I invite you to read this fine poem:

350: Science --> Poetry --> Music

350 parts per million is the "safe upper limit" for CO₂ in our atmosphere presented by NASA scientist Jim Hansen in December 2007 and widely agreed upon.  From that number 350.org .was born. On October 24, 2009, 350 Poems celebrated an international day of climate action with a posting, from poets all around the world, of 350 poems of 3.5 lines each --  each responding to concern for man-made climate change. 

A thousand and fifty-one waves

Twenty-five years ago I had an enormous appetite for poems by Stevie Smith (1902-1971).  I loved the way that they seemed so unstudied -- playful and yet spot on and profound.    Smith did not use much mathematics in her poetry, but she wrote this poem, "Numbers." 

Half-twist and link -- in a Sestina

     Mobius strip       by Heidi Willamson

     A simple science trick to try at home.
     Half-twist a slip of paper. Link the ends
     to make an ‘O’. Take a pencil, trace a line that loops
     the shape formed by the surface. See
     how the in and out sides merge. The join
     tangles dimensions. There’s no front or back.

Lieber's INFINITY -- poetic prose

It has surprised me to discover that some of my best-remembered learning took place at the hands of teachers I did not particularly like.  One of these was a professor who introduced me, via outside reading assignments, to books by Lillian R. Lieber (1886-1986).  Her free-verse-style lines in Infinity:  Beyond the Beyond the Beyond gave me insights into the calculus I had recently completed as well as the set theory of my current course. (Lieber wrote not just as a mathematician but also as a human being, as a wonderfully informed and openly opinionated person.  For this, too, I treasure her work.)

Some cat!

My title is a borrowing from E. B. White's Charlotte's Web -- which I saw recently with grandchildren at Glen Echo Park's Adventure Theater. It (the title above) refers to my wonderful Himlayan, Noah, who lived to 15 years and 3 months;  this posting is done in his memory.  Herein we connect cats with mathematics.

The hypotenuse of an isosceles triangle

Detroit poet, Philip Levine, has been selected as the new Poet Laureate of the United States. Selected by the librarian of Congress (James Billington), Levine follows poet W. S. Merwin in the honored position.  A Poet Laureate is responsible merely for giving readings in October and May but some laureates also use the position to proselytize for poetry.   Here, from Levine's early collection, What Work Is (Knopf, 1992), is a poem that looks back on a math-art moment in a middle-school classroom.

Can a mathematician see red?

Held late in July, this year's 2011 Bridges (Math-Arts) Conference in Coimbra, Portugal included a poetry reading for which I'd been invited to read but was, at the last minute, unable to attend. (See also 26 July 2011). Poets Sarah Glaz and Emily Grosholz each, however, read favorite selections from my work.  Glaz read one of my square poems, "The Bear Cave" (see 19 June 2011) and Grosholz read the poem shown below, "Can a Mathematician See Red?"

Banach's Match Box Problem

A poetry collection by Susan Case (see also 5 July 2011 posting)  -- The Scottish Cafe (Slapering Hole Press, 2002) -- celebrates the lives and minds of a group of mathematicians in Poland during World War II. Its observations and insights add a new dimension to the important story of the Scottish Book to which it refers -- a book in which the mathematicians reorded their problems and solutions. First published in a mimeographed edition in 1957 by Stanislaw Ulam, The Scottish book: mathematics from the Scottish Café (Birkhäuser, 1981) may now be seen and searched at GoogleBooks.  Case's collection includes statements of two of the Scottish Book's problems:  here, below, is "problem 193" -- which I offer as a "found poem."  A photo of its Scottish Book solution follows.

Cantor Ternary Set

The second issue of the Journal of Humanistic Mathematics has recently been posted -- with more new poems.  The first issue contained a poem by Philip Holmes about one of the most amazing collections of numbers in all of mathematics, the  Cantor Ternary Set.  This set, discovered by Henry John Stephen Smith (1826-1883) but popularized by Georg Cantor (1845-1918) consists of all the real numbers whose base 3 or ternary representations involve only the digits 0 and 2. Like a fishing net, the Cantor Ternary Set is mostly holes. "Gaps" by Philip Holmes spreads it out before us -- and reflects on what else it may represent:

Puzzle play

In volume 4 of The World of Mathematics (James R Newman, Editor; Dover 2003), in a section entitled "Amusements, Puzzles, and Fancies," is an essay by Edward Kasner and James R. Newman entitled "Pastimes of Past and Present Times." This piece is prefaced by a quote from Mark Twain: "Work consists of whatever a body is obliged to do, and play consists of whatever a body is not obliged to do." One of the characteristics that mathematicians and poets have in common  is that both enjoy mind-play -- mental adventures with ideas or numbers or words, dancing and shaping into some new thing.

Mathematical Induction -- principle, perhaps poem

One of my teachers -- I think it was Mr Smith in "College Algebra" during my freshman year at Westminster -- gave me these words to remember:

     When confronted
     with a statement
     that seems true
     for all positive integers
     the wise student
     uses mathematical induction
     as her proof technique. 

Bridges in Coimbra

     Newton's binomial is as beautiful as Venus de Milo.
     What happens is that few people notice it.

Little Infinite Poem

   Little Infinite Poem       by Federico Garcia Lorca

               For Luis Cardoza y Aragón

      To take the wrong road
   is to arrive at the snow,
   and to arrive at the snow
   is to get down on all fours for twenty centuries and eat
         the grasses of the cemeteries.

The wind, counting

     Who can ever forget
     listening to the wind go by
     counting its money
     and throwing it away?

Finding a square root

Here is an old poem (1849) by George Van Waters that offers instruction on finding a square root. This process was part of my junior high learning at the Keith School in Indiana, PA lots of years ago but I suppose the algorithm is seldom taught in 21st century classrooms.  (In case the poem's directions are unclear, additional instruction is offered here.)

I have dreamed geometry

   Descartes     by Jorge Luis Borges

   I am the only man on earth, but perhaps there is neither earth nor man.
   Perhaps a god is deceiving me.
   Perhaps a god has sentenced me to time, that lasting illusion.
   I dream the moon and I dream my eyes perceiving the moon.
   I have dreamed the morning and evening of the first day.

Seeking a universal language

Is mathematics a universal language?  Not only is this universality often postulated but also it was said  -- some decades back -- that devices were broadcasting into space the intial decimal digits of pi, expecting that other intelligent beings would surely recognize the sequence of digits.  Robert Gethner examines this arrogance in a poem.

Ancestry -- what counts

Etheridge Knight began writing poetry while an inmate at the Indiana State Prison and published his first collection, Poems from Prison, in 1968.  His poem "The Idea of Ancestry" shows us what a man in prison finds time to count:

   The Idea of Ancestry   by Etheridge Knight

          1
  
   Taped to the wall of my cell are 47 pictures: 47 black
   faces: my father, mother, grandmothers (1 dead), grand-
   fathers (both dead), brothers, sisters, uncles, aunts,
   cousins (1st and 2nd), nieces, and nephews. They stare
   across the space at me sprawling on my bunk. I know
   their dark eyes, they know mine. I know their style,
   they know mine. I am all of them, they are all of me;
   they are farmers, I am a thief, I am me, they are thee.

Mathematicians at work

     About her collecton, The Scottish Café (Slapering Hol Press, 2002), Susan Case offers this note:
     This series of poems is loosely based upon the experiences of the mathematicians of the Scottish Café, who lived and worked in Lvov, Poland (now L'viv, Ukraine), a center of Eastern European intellectual life before World War II, close to the area from which my own ancestors emigrated to the United States.  A book, known as the Scottish Book, was kept in the Café and used to write down some of their problems and solutions.  Whoever offered a proof might be awarded a prize.
     Here is "Fixed Points," the opening poem from Case's collection:

Mathematicians divide

One of my fine graduate courses at Hunter College was a "World Poetry" course taught by William Pitt Root.  One of our texts was Against Forgetting:  Twentieth-Century Poetry of Witness (W W Norton, 1993), edited by Carolyn Forché.  In this collection is found "To Myself," a poem that confronts fear, by Abba Kovner (1818-1987), a hero of anti-Nazi resistance. Kovner dares to open the poem with the word "Mathematicians."

5 x 5 and 6 x 6

Many poets have found the sonnet to be an ideal poetic form -- its iambic pentameter lines are like five heartbeats assembled in a single breath;  its fourteen lines are a good number for considering a matter carefully. My own frequent form is different -- not a sonnet but a square of some or another dimension.   Here are two of my recent syllable-squares.

     I squint with tension,
     puzzle over this:         
     dissatisfaction's
     itchy appetites
     are my happiness.

The Joys of Mathematics

   The Joys of Mathematics     by Peter Boyle

   At fifty I will begin my count towards the infinite numbers.

   At negative ninety nine I will start my walk towards the
      infinitesimally small.

Creation Myth on a Mobius Band

On the  website of Bert-Jaap Koops, I found this small poem by a poet I admire greatly, Howard Nemerov (1920-1991).

     Creation Myth on a Moebius Band   by Howard Nemerov

     This world’s just mad enough to have been made
     by the Being His beings into Being prayed.

Something for nothing

     Among my favorite mathematical ideas are the seeming-paradoxes -- notions that require a twist and a turn and a leap before one can say "aha."  Using a symbol for "nothing" is one of those leap-requiring ideas.  I don't remember when I first understood zero, but I have enjoyed watching my children -- and now grandchildren -- grapple with ideas of things that are absent rather than present. 
     Here, from Hailey Leithauser, is a poem  that celebrates the cipher. 

Circling -- with Rilke

Ranier Maria Rilke (1875-1926) was born in Prague but emigrated to Germany and is one of the great modern lyric poets.   The following Rilke poems draw on images of circles.

Found in Flatland

Over the years I have shared with friends and students my copy of Edwin Abbott's Flatland (first published in England in 1884) and, alas, not all of these other readers have matched my level of excitement with the small volume.  Even though the book's Victorian attitudes are mostly at odds with my own views, still the tiny book opened me to possibilities of new ways of seeing. Since observing the Flatlanders stuck in two dimensions from my advantageous three-dimensional position, I have wondered how I can now make the leap from three to four or more dimensions.

Stanescu - poetic mathematics

Today I found a link to a recent article, "Matematica şi poezia," that considers commonalities among the arts and mathematics and, therein, mentions a poem by Nichita Stanescu (1933-1984) which Gabriel Prajitura and I have translated.  The poem, "Poetic Mathematics," is dedicated to Romanian mathematician Solomon Marcus.  Here is Gabi's and my translation: 

Lagrange points

The Italian-French mathematician Josef Lagrange discovered the existence of five special "Lagrange points" (aka Lagrangian points) in the vicinity of two orbiting bodies where a third, smaller body can orbit at a fixed distance from the larger ones. More precisely, Lagrange Points mark positions where the gravitational pull of the two large bodies precisely cancels the centripetal acceleration required to rotate with them. Poet Catherine Daly considers these points in a poem:  

Counting on things -- a prose poem

Russell Edson is one of the contemporary masters of the prose poem (a poem whose words are organized into paragraphs rather than stanzas). A selection from May Swenson's prose poem (and short novel) "Giraffe" is available in the October 19 blog posting. Here is Edson's poem "One Two Three, One Two Three" -- which considers the secrets hidden inside one's head.  Another mind, even that of one of our children, is a mystery incompletely known to any of us.

Right Triangle

The shape of a poem influences our reading of it -- short lines cause reading with lots of pauses whereas we read long lines quickly to get the entire line completed in a single breath. Moreover, some poetry is intended to be primarily visual -- to be taken in as a seen-image rather than read.  UBU Web offers several example of early visual poetry and one may also explore the  UBU Web site for modern examples.  Visual poetry may also be termed "concrete" poetry; consider, for example, "Concrete Block" by Michael J. Garofalo:

Math lyrics -- Lehrer et al

Mathematicians with poetic tendency often use their word-talents to write song-lyrics rather than poems; a master of the song-writing art was/is Tom Lehrer.  As an undergraduate at Harvard in the 1940s,  Lehrer majored in mathematics; he is best known for songs he recorded in the 1950s and 1960s.  Here are Lehrer's lyrics for "The Derivative Song" -- written to be sung to the tune of "There'll Be Some Changes Made" (by Benton Overstreet, with original lyrics by Billy Higgins).

A square poem of Romania

When I'm working on a poem that resists my efforts to express what I must say, sometimes I turn to the square for a rescue -- that is, I attempt to find the best words by re-forming the poem as a square (same number of lines as syllables per line).  That is how I came to the following poem, "The Bear Cave,"  (a 9 x 9 square). 

Fear of math

California poet Carol Dorf is a high school math teacher (and has taught in a science museum) -- and images from math and science permeate her work.  An article on math anxiety (and its connections to the brain) in today's Washington Post brought to my mind this poem of hers: 

Once a student of Euclid

The Chair     by Charles Simic

The chair was once a student of Euclid.

The Bridges of Konigsberg

From the August 1997 issue of The Mathematical Intelligencer, we have this poem by Judith Saunders about a long-standing puzzle solved solved by the mathematical giant, Leonhard Euler (1707-1783).

Hikmet -- painting with numbers

Living is no laughing matter . . . 

These are words of Turkish poet, playwright, novelist and memoirist Nazim Hikmet (1902-63), who spent much of his life in prison or exile for his political beliefs.  In the following poem by Hikmet we see a portrait that builds from the numbers that characterize the landscape of Ibrahim Balaban's painting.  As you read Hikmet's poem, consider the value of numbers in portraiture.  Though they do not have the textures of color nor the movement of lines, numbers have shapes and edges that may much enrich our seeing. 

Spacetime

   Spacetime     by Miroslav Holub (1932-1998)

   When I grow up and you get small,
   then --

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).

Poems with permutations

     Below, in the May 16 posting, this blog considered all of the permutations of a few words -- in search of "the best" arrangement. Today we illustrate word-permutations in poems.
     First, a few lines from poet Gertrude Stein (1874-1946) -- who was masterful in her distortions of ordinary syntax and in her use of language in new ways. Stein played with both repetition and rearrangement; here is a brief example:

     Money is what words are.
     Words are what money is.
     Is money what words are.
     Are words what money is.

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?

Would rationalists wear sombreros?

This final section of "Six Significant Landscapes," by attorney and insurance executive (and poet) Wallace Stevens (1879-1955), playfully explores the limitations of rigid thinking. 

If p, then q.

     Today's posting (as also on April 13)  presents variations of the conditional statment -- a sentence of the form "If ___, then ___" in which mathematical theorems often are expressed. (For example, "If m is an odd integer, then m² is an odd integer.")   More generally, a conditional is a statement of the form "If p, then q" -- where p and q denote statements. Poet E. C. Jarvis plays with the language of logical statements and with the idiomatic phrase "Mind your p's and q's" in his poem, "A Simple Proposition."

Blogger edde addad had an undergraduate major in creative writing -- and later earned a PhD in computer science.  He has written about and created poetry-generating programs. addad is one of the contributors to the blog Gnoetry Daily -- which offers ongoing discussion and examples of collaborative human-computer poetry generation.  Here is  "Mystery" -- a poem generated by eGnoetry (assisted by addad!):

Permuting words and and enumerating poems

Caleb Emmons teaches mathematics at Pacific University.  Here is his very-clever description of the requirements for a poem to be a sestina -- spelled out in a poem that is itself a sestina.  (A sestina has 39 lines and its form depends on 6 words -- arrangements of which are the end-words of 6 6-line stanzas; these same words also appear, 2 per line, in the final 3-line stanza.) 

A jar in Tennessee

     Several of my early insights concerning the connections between poetry and mathematics grew from ideas presented by poet Jonathan Holden -- of whom interviewer Chris Ellis (in 2000) asked this question:
     Ellis:  You have drawn similarities between poetry and mathematics. Can you explain the association or similarity between poetry and math in a way the mathematically challenged can grasp?
     Holden: The "poetry and mathematics" analogy was simply to demonstrate, for those with some mathematical sophistication, that both languages "measure" things.

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 

Perpendicularity -- a symmetric relation

     In 2010 both my October 13 and November 20 posts feature small poems by the French poet Guillevic (1909-97). Strongly drawn to his work, I have purchased the collection Geometries (Englished by Richard Sieburth, Ugly Duckling Presse, 2010); Guillevic has found in each geometric figure a personality and a voice. Buy the book and enjoy! Here is one of my favorites from the collection:    

Attitudes of Numbers

     I like Bruce Snider 's "The Certainty of Numbers" (which you may already have found online at The Poetry Foundation website, featured in the April 14  posting) even though I disagree with the initial attitude toward mathematics expressed by its narrator.  Writing a poem can be a voyage of discovery with the narrator's view flexing as the poem progresses.  
     Snider's poem brings to mind a view of mathematics that repeatedly bothers me:  I wonder why some people -- who would not complain about the fixendess of spellings of "cat" or "dog" or "sum" -- dislike mathematics for the so-called rigidity of  arithmetic facts such as "2 + 4 = 6."  ? ? ?

Earth Day, 2011

      My father, a farmer, was respectful of our earth's resources.  Replenish what you take, he taught.   But some of us consume without replacement as if the earth is infinite in its capacities. 
     When growth is exponential, we may not see its consequences before it is too late.  (Have we already destroyed the balances of nature?)  The following 8 x 8 syllable-square poem restates a oft-used math-textbook question -- and reminds us that little time may be left to solve environmental problems.   

Two and four and eight and birds

Pennsylvanian Craig Czury works as a travelling poet in schools, homeless shelters, prisons, mental hospitals, and community centers around the world.  Czury sent me the following translation, "Writing Sheet," by Willie Westwood of a poem by Jacques Prévert (1900-1977) -- the original French version  may be found at Westwood's site (scroll down).

Teaching math with a poem

Sarah Glaz is an algebraist (University of Connecticut) who uses poetry to teach mathematics. At her web page, scroll down to "Recent Articles" to see titles and links to three such papers.   One of the articles is "The Enigmatic Number e: A History in Verse and its Uses in the Mathematics Classroom" -- and it contains an annotated version of the poem whose opening stanzas are found below; it's found in the Digital Library of the Mathematical Association of America (MAA), Loci:  Convergence (April 2010). 

A picture should extend beyond its frame

Since April is Mathematics Awareness Month -- with theme "Unraveling Complex Systems" -- this blogger has been seeking out poems that embrace "complexity."  Today we have a selection by British poet, novelist, and critic John Fuller from his Newdigate prize-winning poem of 1960, "A Dialogue between Caliban and Ariel.". 

Finding poems with "numbers"

     Here's a quick and enjoyable activity:
     Go to the website for The Poetry Foundation.   Browse for a bit and, when you have completed your look-around, go to the search box toward the upper right and enter the word numbers, then click on the search button to bring a list of results.  On that new page, go to the left column menu and click on Poems.   Enjoy "Number Man" by Carl Sandburg and several other poems.
     When your time permits, search using a second mathematical term, and a third.  Bookmark the site.  April is National Poetry Month and Mathematics Awareness Month.  Celebrate!

Conditional statements

The "If ... , then ... ." statements of mathematical theorems are often termed "conditionals." We have, for example, the conditional, "If x < 3, then x² < 9."  And so on.  Formal conditional statements in a poem can give it the feel of mathematics, even if no mathematical terminology is used.  This is  illustrated in "Omens" by the Romanian poet Marin Sorescu (1936-1996); Sorescu's poem also treats us to word-play  -- with allusions that range from nursery rhymes to religious narratives. 

What can mathematics do?

For many, mathematics offers interpretive links between a mind and the truths it seeks to know,  the same role that a story plays in this poem -- "Story Water" -- by Jelaluddin Balkhi Rumi (1207 - 1273). 

A poetic perspective on algebra

     Last Monday (April 4), the Washington Post had an article concerning the value of Algebra II  as a predictor of college and work success.  Since then I have heard numerous successful people point out that they did not have the cited course.   Also on April 4, NPR had a feature on the advantages of being bilingual.   My own mind joined these two stories --  for me, algebra is a second language and has enabled my learning of lots of other things.
     Colette Inez 's poem "Forest Children" uses the language of poetry to speak of algebra (and of her concern for shrinking woodlands).

What color is 3?

     Long before there were six-digit hexadecimal codes for color (red #FF0000 or green #000800), there were paint-by-number craft activities.  And there is synaesthesia (syn -joined, aesthesia -sense),  a neurological condition in which two or more senses are connected. For example music might be "seen" in colours and patterns, or taste may have shapes, or letters and numbers have textures.
     Miroslav Holub (1923-98), Czech poet and research scientist (and one of my favorite poets) establishes number-color pairings in the following poem:

April -- month of poetry and mathematics

April is both National Poetry Month and Mathematics Awareness Month  (with theme this year being "Unraveling Complex Systems").  Today's poem by physicist Richard Feynmann (1918-1988) celebrates both poetry and complexity; from the Epilogue of  Feynman's book, What do you care what other people think?, we have these lines: 

Coleridge: A Mathematical Problem

 "A Mathematical Problem" by Samuel Taylor Coleridge (1772-1834) -- found online at Elite Skills Classics -- uses verse to describe construction of an equilateral triangle; Coleridge introduces the poem with a letter to his brother telling of his admiration of mathematics, a view rather rare among poets.   

The Nightmare of an Unsolved Problem

Back in the 1980s when I first met the Collatz conjecture in a number theory textbook it was stated this way:
     Start with any whole number  n :
          If  n  is even, reduce it by half, obtaining  n/2.
          If n is odd, increase it by half and round up to the nearest whole number, obtaining  3n/2 + 1/2 = (3n+1)/2.   Collatz' conjecture asserts that, no matter what the starting number, iteration of this increase-decrease process will each time reach the number 1.
