Girls can do EVERYTHING!

     In a conversation years ago with one of my math colleagues at Bloomsburg University,  each of us learned that the other had grown up on a farm.  My colleague credited the problem-solving requirements of farm-life with being good training for mathematics. In time, I came to agree with him.  Some environments EXPECT you to be a problem-solver and, in spite of yourself, you comply.  I have tried to write poetically about this.  My efforts so far include these 3x3 syllable-square poems.

Girls who change                              

light-bulbs change                             

everything!                             

     Girls who prove

     theorems can

     do it all!

     And, here is a link to a recent NPR story about the underestimates that girls make about how smart they are -- so little has changed since I was a girl.  Hoping I can help to change things for my granddaughters!

Ultimately, all mathematics is poetry . . .

     A popular vote on the truth of "all mathematics is poetry" might not lead to its affirmation. Because mathematics is a concise language, with emphasis on placing the best words in the best order, it often is described by mathematicians and scientists as poetry.  Alternatively, and more accessible to most readers than poetic mathematics, we find verses by poets who include the objects and terminology of mathematics in their lines.
     Perhaps due to aesthetic distance (featured in The Art of Mathematics by Jerry King), non-math poets like Christina M. Rau are able to be more playful in their uses of mathematical vocabulary than mathematicians dare to be.  Enjoy below several stanzas from Rau's collection, Liberating the Astronauts -- which also includes titles like "Chasing Zero" and "Kepler's Laws" -- soon to be released by Aqueduct Press.

All Mathematicians are Equal!

     Last Saturday's Women's March in Washington was one the great events of my lifetime -- the feeling of community that bonded us participants was palpable.  We chatted and hugged and celebrated our differences and our common ideals. Here is a photo of the sign that I carried and, beneath the sign, are links to poems about women in mathematics who struggled to be considered equal.

This is the sign I carried at the Women's March on January 21, 2017.

This link leads to "Hanging Fire" by Audre Lorde.  This link leads to a few words of mine, "Square Attitudes."  A posting on girls and mathematics includes samples from Sharon Olds and Kyoko Mori and is available here.

Dickens, from A Tale of Two Cities

     Today I am facing tomorrow and the inauguration ceremony of Donald Trump as the 45th President of the United States.  With many uncertainties and little mathematics in mind (see, however, math-poem link below), I have looked back to the opening words of A Tale of Two Cities by Charles Dickens (1812-1870). Published in 1859, these words echo some of my thoughts today.

       It was the best of times, 
       it was the worst of times, 
       it was the age of wisdom, 
       it was the age of foolishness, 
       it was the epoch of belief, 
       it was the epoch of incredulity, 
       it was the season of Light, 
       it was the season of Darkness, 
       it was the spring of hope, 
       it was the winter of despair, 
       we had everything before us, 
       we had nothing before us . . .

     Here is a link to a poem posted in 2014 that also features the words of Dickens.  Written by Halifax mathematician and poet Robert Dawson, that 2014 poem was formed by applying a mathematical procedure to a passage from Dickens' Great Expectations. 

Celebrate Martin Luther King

     Today is our public celebration of the January 15 birthday of Martin Luther King, Jr (1929-1968) who was both preacher and poet in the "I have a dream" speech he delivered on the steps at the Lincoln Memorial in Washington D.C. on August 28, 1963. 

Dr King's speech began with:

     Five score years ago, a great American,
     in whose symbolic shadow we stand
     signed the Emancipation Proclamation.
     This momentous decree came as a
     great beacon light of hope
     to millions of Negro slaves who had been
     seared in the flames of withering injustice.

Poems starring mathematicians

      One of the challenges posed by a multi-year blog is locating interesting old posts.  One of  my frequent early topics was "poems starring mathematicians" and I offer links to several of these from 2011 below:
     December 8 "Monsieur Probability" by Brian McCabe
     November 13  My abecedarian poems, "I Know a Mathematician" and "Mathematician" 
     July 5  "Fixed Points" by Susan Case -- about mathematicians in Poland during WWII
     July 2  "To Myself" by Abba Kovner
     January 30  "Mr Glusenkamp," a sonnet to a geometry teacher by Ronald Wallace
     January 28  "Mathematician" by Sherman K Stein

     And, here is a link, via PoemHunter.com to "The Mathematician in Love," a poem by William John Macquorn Rankine, a poem that appears also in the multi-variable  anthology, Strange Attractors:  Poems of Love and Mathematics (AK Peters, 2008), edited by Sarah Glaz and me.  Here is the first (of 8) stanza of Rankine's entertaining poem:

          A mathematician fell madly in love
          With a lady, young, handsome, and charming:
          By angles and ratios harmonic he strove
          Her curves and proportions all faultless to prove.
          As he scrawled hieroglyphics alarming.

2017 is prime!

     For her December 31 posting in Roots of Unity (Scientific American blog) mathematician Evelyn Lamb wrote about favorite primes -- and starring in her list is our new year-number, 2017.
     My own relationship with primes also is admiring-- here is an excerpt from my poem, "Fool's Gold," (found in full here) that suggests a prime as a suitable birthday gift:

          Select and give a number.  I like large primes—
          they check my tendency to subdivide
          myself among the dreams that tease
          like iron pyrites in declining light.

     "Fool's Gold" appears in my chapbook, My Dance is Mathematics (Paper Kite Press, 2006); the collection is now out-of-print but is available online here. 
     Several poems about primes have been included in earlier postings in this blog.  For example, here is a link to a 2013 posting of "The Sieve of Erastosthenes" by Robin Chapman.  And, for further exploration, here is a link to the results of searching the six years of postings using the term "prime."

Happy New Year! -- Resolve to REWARD WOMEN!

     My December 27 post celebrated the life of Vera Rubin (b 1928) who died on Christmas Day -- and a more recent Washington Post article by columnist Petula Dvorak has used the example of Vera Rubin to call further attention to ongoing discrimination against high-achieving women.

     On a different note, my e-mail "poem-a-day" from poets.org is "Earthy Anecdotes" by Reading, Pennsylvania poet Wallace Stevens (1879-1955)-- follow this link to visit the poem (with its morsel of mathematics) and see the vivid image of Oklahoma bucks moving in "a swift, circular line".

Happy New Year, 2017!

Celebrate Vera Rubin -- a WOMAN of science!

     This morning's Washington Post carried an obituary of Vera Rubin (1928-2016),  a pioneering astronomer who confirmed the existence of dark matter.  Yesterday's NPR feature -- noting Rubin's death and celebrating her life -- contained several quotes from this outstanding scientist about women's roles.  Two of these poetic statements I have shaped into syllable-square stanzas:

World wide, half

of    all    brains

are    women's. 

Post-Christmas reflections from W. H. Auden

     A favorite writer whose works I enjoy again and again is English poet Wystan Hugh Auden (1907-1973). Here is a mathy excerpt from a very long Auden poem (around 1500 lines) entitled "FOR THE TIME BEING: A Christmas Oratorio," written during World War II and available in his Collected Poems.   

     The Christmas Feast is already a fading memory,
     And already the mind begins to be vaguely aware
     Of an unpleasant whiff of apprehension at the thought
     Of Lent and Good Friday which cannot, after all, now
     Be very far off. But, for the time being, here we all are,
     Back in the moderate Aristotelian city
     Of darning and the Eight-Fifteen, where Euclid's geometry
     And Newton's mechanics would account for our experience,
     And the kitchen table exists because I scrub it.

Another mathy Auden poem, "Numbers and Faces," is available here.   And this link leads to more of his work.

Christmas is coming and I have looked back to earlier posts for holiday greetings -- a version of the growing snowball poem above was first posted in 2012 and here, from 2010, is a Christmas verse that celebrates pi:

Remembering Thomas Schelling (1921-2016)

     On December 13, Nobel-prize-winning economist Thomas Schelling (b 1921) died.  I had the privilege of meeting this outstanding scholar in Cambridge, MA back in 1980 when I dropped by his office after hearing him lecture at the Kennedy School of Government.  I became very interested in his ideas of critical mass (found along with lots of other good stuff in Micromotives and Macrobehavior and eventually included the topic in a textbook that I wrote  for a liberal arts mathematics course, "Mathematical Thinking," that I helped to develop at Bloomsburg University.
     I want to honor Schelling with a poem, but . . .

        I
        can’t
        find a
        poem for
        Thomas Schelling – thus
        I am compelled to write this Fib.
        Thanks for thinking well, for sharing your keen thoughts with us.

When one isn't enough ... words from a Cuban poet

     Last week I traveled (as part of an organized people-to-people program) to Cuba.  I will need many days to sort and digest and organize the details of that experience.
     Neither poetry nor mathematics was part of our Cuba schedule but I did have a chance to visit the sparse collection at La Moderna Poesia in Havana and to purchase their only two bilingual poetry collections (by poets José Martí and Nicolás Guillén).  The PoetryFoundation website has introduced me to the work of Cuban poet Omar Pérez  (son of Ernesto "Che" Guevara) and I found there, at this link,  Pérez's poem "The Progression"  -- which includes some mathematical ideas.

The Progression     by Omar Pérez  
                                             translated by Kristin Dykstra 

When one isn’t enough, you need two
when two aren’t enough, you need four
with four the progression begins, moving toward a number
that schoolteachers will call absurd.   

Celebrate MATH-POETRY at JMM (1-5-17) in Atlanta

     Repeating what has become an annual tradition, the Joint Mathematics Meetings of 2017 in Atlanta will include a poetry reading. 

Thursday January 5, 2017, 5:30 p.m.-7:00 p.m.
Regency Ballroom VII, Ballroom Level, Hyatt Regency

Here is info about the reading and how to participate:     Poetry + Math, organized by Gizem Karaali, Pomona College; Lawrence M. Lesser, University of Texas at El Paso; and Douglas Norton, Villanova University; Thursday, January 5, 5:30–7:00 pm.  All who are interested in mathematical poetry and/or mathematical art are invited.

Sponsors for this event are the Journal of Humanistic Mathematics and SIGMAA ARTS.  A complete program for the Mathematics Meetings is available here.

Number-rhymes from Muriel Spark

     A dozen years ago I visited Edinburgh and there became acquainted with the poetry of Scottish writer Muriel Spark (1918-2006)  -- prior to that visit I had known Spark only as a novelist.  Today -- prompted by Thanksgiving celebration with grandchildren -- I have remembered an English rhyme that my own grandmother teased me with in childhood, "Going to St Ives" and, from there, I've recalled a pair of Spark's rhymes that follow a similar pattern.  I offer them below; despite strong rhyme, these are not entirely light fare--instead, they make us aware of the sad multiplication of bonds and wounds . . .

       Conundrum     by Muriel Spark

       As I was going to Handover Fists
       I met a man with seven wrists.
       The seven wrists had seven hands;

An immeasurable continuum

This poem by Emily Warn (a founder of PoetryFoundation.org) uses mathematical terminology to introduce us to the immeasurable horror of death by slow torture.  May our nation never again engage in such atrocities!

The Vanishing Point     by Emily Warn

You slow down to watch cumulus clouds stream across the
sky. You choose a more circuitous route home and pass a
tree with white bags tied around random apples. The apples
remind you of clouds, how each hangs in the sky, singular
yet part of a flock. Each item in the flock is a coordinate of
earth and sky, enumerating space. The flocks of apples and
clouds are actual infinities, an endless collection of discrete
items that one can conceivably count to the end. This is

A well-constructed language

     California math teacher, poet and editor, Carol Dorf is a vital force in the production and dissemination of mathy poems.  A blog SEARCH using her name will find links to all of my mentions of her activity.  Here is one such link --  to my list of titles of mathy poems in Talking-Writing, an online journal for which Dorf is poetry editor.    Dorf's poem below speaks of Ada Lovelace, a math-woman who has been featured herein on July 16, 2015  and September 18, 2015.

Mathematics is "a well-constructed language."

 Dorf's "Ada" first appeared in Volume 14 of The Mom Egg Review.

Poetry and Protest

      One of the fine new anthologies of 2016 is Of Poetry and Protest:  From Emmett Till to Trayvon Martin, published by W W Norton -- put together by Phil Cushway (Compiler), Michael Warr (Editor), and Victoria Smith (Photographer).  Here, from that collection, are the opening stanzas of Marilyn Nelson's "Cells and Windows" -- a poem that gains much of its power from the awful truth conveyed by its numbers.
 
Cells and Windows          by Marilyn Nelson
             after work by neogeo painter Peter Halley   

Black men in their prime
working years, especially
those without a high school
diploma, are much more likely
to be in jail than white men are.

     I found an lovely little autumn poem (after William Carlos Williams' "The Red Wheelbarrow") by Michael Khmelnitsky -- who declined to let me use it herein, and so I offer a link to it -- enjoy "The Gaussian Function."

Happy Birthday, Marie Curie

Today, November 7, is the birthday of Marie Curie (1867-1934, Nobel prize in physics, 1903).  Curie is celebrated in this poem by Richard Aston, first posted in this blog on December 6, 2014 along with two other math-science-themed poems.

Scientist     by Richard Aston

It took more than a figure, face, skin, and hair
for me to become Marie Curie,
wife of simple, smiling, selective, Pierre
who could recognize — because he was one — my genius.

Calculating costs of pollution ... and other news

     Recently I was browsing through an oldish collection, The Best American Poetry 1999 (edited by Robert Bly) where I found and liked this poem by Marcia Southwick -- a poem that drew me in with its anti-pollution attitudes and its enumeration of some of the costs of pollution.
 
A Star Is Born in the Eagle Nebula     by Marcia Southwick
                           To Larry Levis, 1946–1996
They’ve finally admitted that trying to save oil-soaked
seabirds doesn’t work. You can wash them, rinse them
with a high-pressure nozzle, feed them activated charcoal
to absorb toxic chemicals, & test them for anemia, but the oil
still disrupts the microscopic alignment of feathers that creates
a kind of wet suit around the body. (Besides, it costs $6oo to wash
the oil slick off a penguin & $32,000 to clean an Alaskan seabird.)

Geometry -- in art and poetry

     St. Louis poet Constance Levy is an acclaimed author of children's poetry -- I found her poem "Madinat as Salam" (included below) in the collection, Heart to Heart, (Edited by Jan Greenberg; Abrams Books for Young Readers, 2001),  a beautifully presented and illustrated anthology of poems inspired by American art.  Enjoy!

Make Something of Nothing ... with Bob Dylan

     The puzzle of nothing actually being something is central to our use of numbers -- and I use it today as an excuse to link to a Bob Dylan song and celebrate his recent Nobel prize.  Below I offer one (the 3rd, of six) of the stanzas of "Too Much of Nothing" -- followed by a link to the complete lyrics.  (And for those readers seeking other poems of nothing, here is a link to blog poetry from 2011 about division by zero, this link leads to making something of nothing . . .  and this link leads to several nothing links -- it was found via a blog search using the search term "zero.")

from     Too Much of Nothing     by Bob Dylan

          Too much of nothing
          Can make a man abuse a king
          He can walk the streets and boast like most
          But he wouldn’t know a thing
          Now, it’s all been done before
          It’s all been written in the book
          But when there’s too much of nothing
          Nobody should look

Here is a link to the complete lyrics of "Too Much of Nothing."  Enjoy.
                                          

Have a Happy "Hamilton Day"

 April 15-23, 2016 is Maths Week in Ireland.

 

     AND, as this recent Slate article by Katharine Merow announces, in Ireland October 16 is "Hamilton Day" -- named for Irish mathematician William Rowan Hamilton (1805-1865).  Math-science writer Merow entertainingly describes Hamilton's mathematical contributions and suggests that the holiday be celebrated by more of us than just Ireland. 
     This blog adds some poetry to the celebratory fare -- here is a link (from a 2011 posting) to a poem by Hamilton, himself and this January, 2016 link leads to a sonnet about Hamilton by poet Iggy McGovern.

From order to chaos -- "Fig Tree Rag"

     Robert Dawson, a mathematician and poet from Halifax, Nova Scotia, is wide-ranging in the mathematics that he includes in poetry.  Here is a link to my posting of his "Statistical Lament."  Still others may be found with a SEARCH using the poet's name.
     Dawson's poem below is motivated by chaos and period doublings -- and their patterns -- a complicated system that, under certain conditions approaches a number called Feigenbaum's constant.  (Mitchell Feigenbaum is a mathematical physicist who did pioneering work in chaos theory.   "Feigenbaum" is a German surname meaning "Fig Tree" -- hence the title of the poem.)  Probably you will want to read the poem aloud to get a feel for the rhythmic patterns -- and chaos -- that Dawson has designed for us. 

Fig Tree Rag    (after Scott Joplin)   by Robert Dawson

The music drifts across the room:
from clarinet and saxophone
a sliding stream of melody,
piano chords beneath it, and
upon the cymbal and the snare
the drummer paints a lazy beat
with wire brushes, regular
and cool and uninflected as
a music teacher’s metronome.

She argued for Newton's physics

     Here, by Voltaire, is a poem about mathematician/scientist Émilie du Châtelet (1706-1749) -- who explained Newton's physics but was not remembered for her own work as she should have been.  

At this link, one may begin to learn about du Châtelet's many contributions.

       The Divine Émilie      by Voltaire (1694-1778)

       Here's a portrait of my Émilie:
       She's both a beauty and a friend to me.
       Her keen imagination is always in bloom.
       Her noble mind brightens every room.
       She's possessed of charm and wit,
       Though sometimes shows too much of it.
       She has, I assure you, a genius rare.
       With Horace and Newton, she can compare.
       Yet, she will sit for hours and hours
       With people who bore her
       And card-playing gamblers.

Be astonished -- National Poetry Day (British)

Today I celebrate British partnership with Romanian poetry!

     One of the internet treasures I have found is to Contemporary Literature Press, the online publishing house at the University of Bucharest which offers bilingual (Romanian and English) presentations of both classical and contemporary work.  The creators say this about themselves:

The Contemporary Literature Press, under The University of Bucharest,

in conjunction with The British Council, The Romanian Cultural Institute, 

and The Embassy of Ireland.

We publish poetry, fiction, drama and criticism, in the original and in translation, 

whether English or Romanian.

We are a well-fused group of staff and graduate students, 

very enthusiastic about our work.

     This particular link from Contemporary Literature Press celebrates British-Romanian week and includes a poem with a bit of mathematics by Australian-born, London-resident poet Katherine Gallagher; I offer it here and invite you also to visit its Romanian translation.

     Take-Off     by Katherine Gallagher

Generating a sonnet -- human vs computer

     News last month from UC Berkeley's School of Information described a computer that writes poetry. In particular, it writes sonnets.  This article describes in much detail the creation of several sonnet stanzas.  This link offers the winner in Dartmouth's 2016 PoetiX sonnet-generation competition -- in which Berkeley earned a second.  Here, from an article in Slate, is an example of what Berkeley's generator produced:

    Kindred pens my path lies where a flock of
    feast in natures mysteries an adept
    you are my songs my soft skies shine above
    love after my restless eyes I have kept.  

A Nest of Worlds -- in verse by Margaret Cavendish

     Margaret Cavendish (1623-1673) was an English aristocrat, scientist, writer and philosopher.  The following interesting and charming poem by Cavendish I found in A Quark for Mister Mark: 101 Poems about Science, edited by Maurice Riordan and Jon Turney (Faber & Faber, 2000). 

     Of many Worlds in this World    by Margaret Cavendish

     Just like as in a Nest of Boxes round,
     Degrees of Sizes in each Box are found:
     So, in this World, may many others be
     Thinner and less, and less still by degree:
     Although they are not subject to our sense,
     A World may be no bigger than Two-pence.

The Bloomsburg Fair -- with theorems and lies . . .

     Along the north branch of the Susquehanna River in east-central Pennsylvania lies the town of Bloomsburg -- known for Bloomsburg University (where I taught math for a bunch of years) and for the Bloomsburg Fair -- an annual celebration that attracts hundreds of thousands of people during each last week of September.  
     I grew up loving fairs -- in my hometown of Indiana, Pennsylvania, the last week of August brought the Indiana County Fair where we celebrated, with livestock and a carnival, the end of summer vacation.
     More than twenty years ago I gathered some of my Bloomsburg Fair memories in a poem.  The entire poem is found at this link; below I offer a sample of the mathy imagery from the poem.

from   The Bloomsburg Fair      by JoAnne Growney  
. . .
       In front of side-show tents,
       a barker barks his come-on-ins.
       Why don't my students receive theorems
       as willingly as passersby
       accept his lies?
. . .
       If parallels will never meet—
       then here's a man with snakes for hair,
       and there's a woman with three eyes.

      This poem appears in the anthology, COMMON WEALTH: Contemporary Poets on Pennsylvania, Edited by Marjorie Maddox and Jerry Wemple, (2005, PSU Press).

Math-woman, be bold!

     During these days in which discrimination against math-women happens again and again I have wanted to write a poem that celebrates us.  My efforts at traditional verse seemed whining.  Sense left me.  Eventually this came:  

     M ultiply
     A xioms,
     T risect
     H yperbolas,
     W ager
     O rthogonal
     M artingales

Dear reader, please share your own words -- via comments below!

A rumor (in verse) about Alfred Nobel

 Before the poem a bit of history about its source of publication:

     The Humanistic Mathematics Network Newsletter (HMNN) was founded by Alvin White (1925-2009) of Harvey Mudd College in the summer of 1987. The Newsletter was later renamed The Humanistic Mathematics Network Journal (HMNJ). The last issue of the HMNJ was published in 2004 -- and a current, related (online, open-accesss) journal is the Journal of Humanistic Mathematics (JHM).  Recently the digital archive of the full run of the HMNN/HMNJ (1987-2004) has become available at this link.
      I was an active participant in HMNJ  -- contributing articles and serving for several years as poetry editor -- and have enjoyed browsing the archives.  One of my articles, "Mathematics and Poetry: Isolated or Integrated" is available here (Issue 6, 1991).   

Explore!  

There's lots more!

     Back in Issue 3 of HMNJ (from 1988) I found these entertaining lines from topologist and math historian William Dunham -- setting to rhyme an an apocryphal tale of why there is no Nobel prize in mathematics.

       For Whom Nobel Tolls    by William Dunham  

       It is well-known that Nobel Prizes
       Come in many shapes and sizes.
       But one is missing from the list --
       The Nobel Math Prize does not exist.  

Keyboard characters make a poem . . .

     Here's poem found in an old email from my Bloomsburg friend, Janice B.  Its authors turn out to be Fred Bremmer and Steve Kroese and they penned it around 1990, using computer keyboard characters, during their student days at Calvin College.  Enjoy!

A Fib (a perfect circle) -- and some math-po links

    1      Not 
    1      one 
    2      circle
    3      is perfect
    5      yet the idea
    8      of circle's useful every day.

The beauty of images and the ideas they represent is central in both mathematics and poetry.  A wonderful resource for works that join these two is the literary website TalkingWriting,com -- whose poetry editor is Carol Dorf, also a math teacher.  Here is a link to a wonderful TW essay from a few years back, "Math Girl Fights Back" by Karen J Ohlson.  This article by Dorf, "Why Poets Sometimes think in Numbers,"  introduces a 2012 collection of mathy poems.  Another collection was posted in the Spring 2016 issue.  In addition, at the TalkingWriting website, you can enter the search term "math" -- as I did -- and be offered 5 pages of links to consider. 

Division by Zero

     At Victoria University in Melbourne, novelist, playwright and poet Tom Petsinis also teaches mathematics.  He participated in the 2016 Bridges Math-Arts Conference in Finland this summer:  here are two of his poems from the 2016 Bridges Poetry Anthology -- and each of them plays with mathematical ideas in new and thoughtful (sometimes amusing) ways.   "Zeno's Paradox" follows this initial poem.  (Names and links for other anthology poets are given below.)

     Division by Zero     by Tom Petsinis

     She could’ve been our grandmother
     Warning us of poisonous mushrooms ‒
     To stress her point she'd scratch
     The taboo bold with crimson chalk.
     It should never be used to divide,
     Or we'd be howled from lined yard
     To pit where cruel paradoxes ruled.
     Her warnings tempted us even more:
     Young, growing full in confidence,
     We’d prove the impossible for fun ‒
     Nothing she said could restrain us
     From showing two is equal to one.   

A counting rhyme, a riddle

     During the summer I had lots of activities with grandchildren -- they all love to read and one of the books we enjoyed together was Counting Rhymes (selected by Shona McKellar, a Dorling Kindersley book, 1993).  Here are a rhyme and a riddle from that collection.

Let's Send a Rocket     by Kit Patrickson

TEN, NINE, EIGHT,                                 We're counting each second,
SEVEN, SIX, FIVE . . .                             And soon it will boom!

We'll send up a rocket,                         Get ready for . . . TWO;
And it will be LIVE .                              Get ready to go . . .
        
FIVE, FOUR, THREE . . .                          It's TWO--and it's--ONE!  
It's ready to zoom!                                We're OFF!  It's ZERO!

                                    RIDDLE -- What animal do these clues describe?

                                    Four stiff-standers,
                                    Four dilly-danders,
                                    Two lookers,
                                    Two crookers,
                                    And a wig-wag.

Twelveness -- a Fibonacci poem from G4G

     Science writer, philosopher, and skeptic Martin Gardner (1914-2010) is perhaps best known for his long-running Scientific American column, "Mathematical Games."  His life and work are celebrated by G4G conferences ("Gatherings for Gardner") held in even-numbered years in Atlanta.  Here fans gather and present fun-mathematics to each other.
     A several-time participant in G4G is Kate Jones of Kadon Enterprises, an organization devoted to the development and distribution of Game Puzzles.  Below in a Fibonacci poem created for the 2016 G4G Jones tells the history of her game-puzzle enterprise.

Many Fibonacci poems use the Fibonacci number sequence 

to determine the numbers of syllables in successive lines of a poem.  

In the following poem, it is the numbers of words that are counted.
 A pentomino is a plane geometric figure formed by joining five equal squares edge to edge.  
There are twelve differently-shaped pentominos; this number gives the title of Jones's poem.

Math-play via verse (with George Darley)

A recent email from Colm Mulcahy -- who seeks out all things Irish -- alerted me to Dublin poet and math-text author, George Darley (1795-1846), and an online archived collection of his poems.    Colm's email had opened the collection to pages 70-71 and there I found -- and had fun reading --  this poem that plays with math.

     A Poetical Problem.      by George Darley

     Once on a time, at evening hour,
     A sweet, and dewy-bosom'd Flower
            Was cradling up to rest ;
     A Pilgrim, wandering near her bed,
     Raised, with his staff, her drooping head,
            And thus the Flower addrest : 

     "From matin-rise to moonlight hour,
     Tell me, my pearly-crested Flower,
            How many a lucid gem
     Hath left the high, cavernal air,
     To form upon thy queenly hair
            A rainbow diadem?" 

Numbers and Faces - poem, anthology

 "Numbers and Faces" is the title of a poem by W. H. Auden that ends with these lines:
            True, between faces almost any number
            Might come in handy, and One is always real;
            But which could any face call good, for calling
            Infinity a number does not make it one.

The complete poem is posted here.

     "Numbers and Faces" is also the title of a small anthology of poems, published in 2001 and containing Auden's poem, that I collected and edited for the Humanistic Mathematics Network.  The anthology has been out of print for many years but a file with its mathy poems is available online here. 
     The Humanistic Mathematics Network (started around 1987 by Alvin White) had a Newsletter and then a Journal but these paper publications faded away around 2004.  The Journal of Humanistic Mathematics emerged in 2011 to fill the void.  Recently I have learned from JHM editor Gizem Karaali, that an online archive of the prior publications is available here.  (Using the search box, I was able to find several of my own years-ago articles, including one from 1994 entitled "Mathematics in Literature and Poetry.")
