Visit JHM for Mathy Poems

     Today I'd like to direct you to the Journal of Humanistic Mathematics, an online open-access journal that features poetry in each issue.  The Table of Contents for the first issue of 2016 is now available here -- and I offer below a poem from Issue 1 of 2015.  (Before sharing the poem "Prisoner's Dilemma" by Raymond Greenwell I want also to mention that JHM is looking for investigative journalists and that today's "Poem of the Day" at Poets.org is "Evolution" by Linda Bierds and inspired by the work of Alan Turing.)
     I am particularly intrigued by Greenwell's poem because the Prisoner's Dilemma is a decision model close to my concerns about the environment. (More comments below.)

       Your best choice is my demise.
       My wise choice is your defeat.    

Using a Fano plane to create a poem

     South Dakota mathematician Daniel May enjoys finding connections between his discipline and other arts -- and herein we consider a constraint-structure for poetry that he has developed using a Fano plane.  In brief, a Fano plane (shown in the diagram below) consists of 7 points and 7 lines (the three sides of the triangle, the three altitudes of the triangle, and the circle) -- with each line containing 3 of the points. 

Fano Plane Diagram

May creates a poem by associating a word with each point of the Fano plane and then creates a three-line stanza for each line of the diagram.  Here is a template for the poem "adore" -- and the poem itself is offered below the diagram: 

Visiting the Australian Poetry Library

     An Australian poet (Erica Jolly) whom I have met through this blog has helped me to learn about the great variety of poetry and related activities that are available on her continent  -- and today I want to link you to the Australian Poetry Library and to offer a mathy poem by Peter Goldsworthy that I enjoyed there.

     1     by Peter Goldsworthy 

       Arithmetic divides 
       and rules the world,
       freezing the flow
       in single frames,
       colourising each
       by numbers.

A sonnet for Napoleon's Theorem

     In geometry, Napoleon's theorem (often attributed to Napoleon Bonaparte, 1769–1821) states that if equilateral triangles are constructed on the sides of any triangle, either all outward or all inward, the centers of those equilateral triangles themselves are the vertices of an equilateral triangle.  In a 2015 lecture at the  University of Maryland,  mathematician Douglas Hofstadter (perhaps best known for Godel, Escher, Bach: an Eternal Golden Braid -- Basic Books, 1970) presented Napoleon’s theorem by means of a sonnet.  Perhaps you will want to have pencil and paper available to draw as you read:

Napoleon's Theorem     by Douglas Hofstadter

Equilateral triangles three we’ll erect
Facing out on the sides of our friend ABC.
We’ll link up their centers, and when we inspect
These segments, we find tripartite symmetry.

Rabbis should learn to solve quadratics

     Thanks to mathemagician Colm Mulcahy who connected me with poet Lisa Dordal -- and thanks to her for permission to offer these lines, entertainingly seasoned with math words:

Why Rabbis Need to Know
How to Solve Quadratic Equations  

                                         by Lisa Dordal (with help from Laurie Samuels)

Because they are good exercise
for your logic muscles, which you’ll need
to work through those pesky J says-P says conflicts of text –- 
the bumpy remains of a Torah affair. 

Tartaglia solving the cubic -- in verse

     Mathematical historians now credit both Cardano and Tartaglia with the formula to solve cubic equations, referring to it as the "Cardano-Tartaglia Formula." Tartaglia is known for reporting solutions of three different forms of the cubic equation in a poem (1534).  Below we offer Boston poet Kellie Gutman's English translation of Tartaglia's verse, followed by the original Italian.

When X Cubed    by Niccolò Tartaglia (1500–1557)       (Englished by Kellie Gutman)

When x cubed’s summed with m times x and then   
  Set equal to some number, a relation    
  Is found where r less s will equal n.

Now multiply these terms. This combination
  rs will equal m thirds to the third;
  This gives us a quadratic situation,    

Not good at math . . .

     Connecticut poet Joan Cannon is a senior who laments her lingering anxiety over mathematics in her poem, "Humility," below.  I found Cannon's poem on Senior Women Web and it is accompanied there by selections from an article by Patrick Bahls entitled "Math and Metaphor:  Using Poetry to Teach Mathematics."  The complete article is available here.

     Humility    by Joan L. Cannon

     Archetypes, mysteries, simple clues
     that only fingers and toes, sticks and stones
     and flashes of inspiration require
     for universes to be disclosed ...
     symbols for functions and formulae
     for proof; logic so easy for some —
     why am I innumerate?  

Math Anxiety

     Recent comments from a friend describing anxiety that seems to freeze his attempts to understand and use a new mathematical concept have caused me to recall and dig out this old poem -- and, by recalling it, to increase my understanding of my friend. 

     The Math Teacher's Golf Lesson     by JoAnne Growney

     My practice swing was perfect --  slow start, easy
     acceleration through the ball to finish high.
     "Beautiful," he said.  "It's time to hit a few."
     I addressed a ball and settled down and swung --
     and missed.  "Concentrate," he said.  I squinted

Soon it will be February -- and Valentine's Day

     Looking back:  on February 12, 2011 I posted math-poetry suggestions for Valentine's Day at this link: Loving a mathematician (Valentine's Day and . . . ).   This posting from Feb 9 2013 offers verse along with an animated drawing of a heart-curve --a cardioid.    And this link goes to a mathematically poetic digital art exhibit (that includes a cardioid) by Guang Zhu.

Poetry from a math teacher's son

     In an earlier post I have noted how effectively mathematicians and their mathematics may be described by poets who are in the same family.  This link, too, leads to portraits of mathematicians.
     Poet and novelist John Updike (1932-2009) was the son of a math teacher and the selection below is a sonnet that begins in the style of a math-class word-problem linking his own age with that of his father.

from  Midpoint     by John Updike

     FATHER, as old as you when I was four,
     I feel the restlessness of nearing death
     But lack your manic passion to endure,
     Your Stoic fortitude and Christian faith.
     Remember, at the blackboard, factoring? 

A sonnet for W.R.Hamilton

      Irish mathematician William Rowan Hamilton (1805-1865) was also a poet (see, for example, this sonnet in a prior posting (13 October 2011).  Irish poet and physicist Iggy McGovern has written A Mystic Dream of 4:  A sonnet sequence based on the life of William Rowan Hamilton (Quaternia Press, 2013). 

The collection is prefaced by this quote from Hamilton:

"The quaternion [was] born, 

as a curious offspring of a quaternion of parents, 

say of geometry, algebra, metaphysics, and poetry."

Here is McGovern's opening sonnet.

GEOMETRY     by Iggy McGovern

Once, any pupil could define me best:
"points, lines, angles and figures", could amuse
The table with the Christmas cracker jest
About 'the squaw' on the hypotenuse! 

The world is round . . . or flat!

British poet Wendy Cope frequently includes edgy humor in her poems (she is, indeed, a prizewinner in light verse) -- and I like that.  In the poem below (found at PoetryFoundation.org and originally published in Poetry in 2006), Cope examines arguments of whether our world is flat or round.  Part 2 of the poem involves the interesting permutation pattern that is called a pantoum (Lines 2 and 4 of each four-line stanza are repeated (approximately) as lines 1 and 3 of the next stanza -- and the final stanza is wrapped into the first).

Differences of Opinion     by Wendy Cope

1     HE TELLS HER

He tells her that the earth is flat --
He knows the facts, and that is that.
In altercations fierce and long
She tries her best to prove him wrong,
But he has learned to argue well.
He calls her arguments unsound
And often asks her not to yell.
She cannot win.  He stands his ground.

The planet goes on being round.   

Counting those who grieve . . .

Each day's email brings me a Poem-a-Day from Poets.org and today's selection by Matthew Olzmann considers the tragedies from gun-violence in our news too often these days. Numbers are "objective" -- and count those who watch and grieve as well as the guns and shooters -- or are they?  Here is an excerpt from Olzmann's poem, "Letter Beginning with Two Lines by Czesław Miłosz":

          . . .   Did I say
          I had “one” student who

          opened a door and died?
          That’s wrong.

          There were many.
          The classroom of grief  

Math is Brewing . . .

For one of my granddaughters who likes poems, I recently purchased If You're Not Here, Please Raise Your Hand:  Poems about School by Kalli Dakos (Aladdin Paperbacks, 1995).  It's hard to find school poems that are non-critical of math -- but this one, at least, has some rhyming fun while cooking it.

Math is Brewing and I'm in Trouble     by Kalli Dakos

       Numbers single,
       Numbers double,
       Math is brewing
       And I'm in trouble,

       If I could mix a magic brew,
       Numbers, I'd take care of you.

Precision leads to poetry . . .

As the year ends, a quote from one of my once-favorite authors, Don DeLillo (in correspondence with David Foster Wallace -- whose Infinite Jest is on my to-read list), earlier offered by Jordan Ellenberg in Quomodocumque.

Quoting DeLillo:

          Once, probably, I used to think that vagueness 
          was a loftier kind of poetry, truer 
          to the depths of consciousness, and maybe 
          when I started to read mathematics and science 

          back in the mid-70s I found an unexpected lyricism 
          in the necessarily precise language 
          that scientists tend to use. 
          My instinct, my superstition 
  
          is that the closer I see a thing 
          and the more accurately I describe it, 
          the better my chances of arriving 
          at a certain sensuality of expression.

And at the BrainyQuotes website is this quote (and many others) by DeLillo (and many others).

For me, writing is a concentrated form of thinking.

HAPPY NEW YEAR!

Can a woman learn science (or mathematics)?

It is not a new idea that women do not have scientific aptitude, that teaching them requires special accommodation.  Here, in a poem by one of the greatest scientists of all time, is a description of a condescending lecture to a female student, individually and behind a curtain, followed by her mocking reply.

Lectures to Women on Physical Science  by James Clerk Maxwell  (1831-79)

I.    PLACE. —A small alcove with dark curtains.
       The class consists of one member.
       SUBJECT.—Thomson’s Mirror Galvanometer.

      The lamp-light falls on blackened walls,
            And streams through narrow perforations,
      The long beam trails o’er pasteboard scales,
            With slow-decaying oscillations.
Flow, current, flow, set the quick light-spot flying,
Flow current, answer light-spot, flashing, quivering, dying.

And now welcome Christmas . . .

Let us sing . . .

(a version of)  The Twelve Days of Christmas

          The twelfth day of Christmas.
          My true love gave to me,
          Twelve lords a leaping,
          Eleven ladies dancing,
          Ten pipers piping,
          Nine drummers drumming,
          Eight maids a milking,
          Seven swans a swimming,
          Six geese a laying,
          Five golden rings,
          Four colly birds,
          Three French hens,
          Two turtle doves,
          And a partridge in a pear tree.

To learn some history of this song (and its variations), frequently sung as a cumulative marathon, see Wikipedia.

Let us not forget . . .

At this time of year in the Northern Hemisphere, many are without shelter -- and are cold.  Let us think of them  -- as Cecil Day-Lewis (1904-1972) does in "A Carol" below (a poem whose lines for the most part maintain an alternating 6-5 syllable count and which contains the small number two).  Let us remember to share our warmth.

       A Carol     by Cecil Day-Lewis 

       Oh hush thee, my baby,
       Thy cradle's in pawn:

Who put the pie in Pythagoras?

Irish poet and physicist Iggy McGovern has written both humorous and serious verse.  Today we have lines from him that startle and amuse -- below I present, with his permission, selections from his collection Safe House (Dedalus Press, 2010).  Here are "Belfast Inequalities" and "Proverbs for the Computer Age":

Belfast Inequalities     by Iggy McGovern
                          for Master Devlin
       Who put the pie in Pythagoras,
       who put the bra in algebra
       and who was the first to say: Let x
       be that unknown quantity in sex?
       the answer's in some chromosome
       and not the sums you do at home 

A student writes poetry for a math class . . .

A recent fun experience for me has been correspondence with Melanie Simms, a poet and math student at Pennsylvania's Bloomsburg University, where I taught for a bunch of years.  Melanie recently completed the course "Mathematical Thinking" -- a course that I helped to develop during my years at BU and one for which I wrote a textbook (Mathematics in Daily Life:  Making Decisions and Solving Problems, McGraw-Hill, 1986).   The course was developed to offer general quantitative skills for students majoring in fields (such as English or Art)  that do not have a specific mathematics requirement.  Melanie's instructor for the course, Paul Loomis, is a singer and songwriter and, with him as first reader, Melanie composed a mathematical poem involving course material.  She has shared the poem with me and has given me permission to post it here.

     The Mathematics of Chance      by Melanie Simms

     The gods of chance
     Have left me skewed
     My distribution, variable!
     With ranges far, and ranges wide
     My navigation's terrible! 

Generalized Pythagorean Theorem--a visual poem?

While thinking about my December 13 posting featuring work by Richard Kostelanetz -- visual poetry with numbers -- I was browsing a fascinating book by Ivan Moscovich, The Puzzle Universe:  A History of Mathematics in 315 Puzzles (Firefly Books, 2015) and came to the following diagram.  I offer it as a visual poem. 

In addition to the squares, what other areas constructed on the sides of a right triangle may be correctly summed to give a third area of the same shape?

Visual poems with numbers

     I have a good friend who does not care for the sorts of poetry that are written today.  When I asked what he likes he cited "When I Was One-and-Twenty" by A E Housman (1859-1936) and the sonnet "Ozymandias" by Percy Bysshe Shelley (1792-1822).   My own preferences in poems, on the other hand, are less certain.  I like to explore, to discover what new things may be said within new forms and constraints.  The following selection, "Notes on Numbers" by Richard Kostelanetz, introduces some of the ideas that this artist/writer/critic explores in his visual poetry -- with numbers -- examples of which are available through links offered at the end of this posting.

Notes on Numbers      by Richard Kostelanetz  

Alphamath - poetry built on 4, 8

Since the late 1960s Toronto poet Victor Coleman has been energetically committed to innovated poetic practices.  A fine introduction to this poet is offered by Alex Porco in this linked review of Coleman's recent book, ivH: An Alphamath Serial (Book Thug, 2010).
          

          ivH: An Alphamath Serial is a book-length poem composed in the tradition 

of such precursors as Pythagoras, who taught that Number was the essence of all things; 

Plato, who argued that geometry was the foundation of all knowledge; 

Colorful mathematics for your smartphone

     "Bhaskara II (1114-1185) was an Indian mathematician and astronomer. He composed the Siddhanta Siromani, a treatise in four parts -- Lilavati (basics), Bijaganita (algebra), Grahaganita (planetary motion) and Goladhyaya (spheres)."
     This quotation comes from an early page of a new (2015) graphic e-book entitled The Illustrated Lilavati -- the text is based on a 1816 John Taylor translation, edited and illustrated for lilboox by Somdip Datta and available for download on smartphones and other devices.  Lilavati (named for the daughter of Bhaskara) was written in 1150 and was a standard textbook for arithmetic in India for many years.
     This e-book contains 25 illustrated problems (and solutions); here is the first:

This blog (then and now) and Pascal

     When I began this blog in 2010, I imagined up to 100 postings -- I saw it as a way to share math-related poetry that I had written and gathered during my years of teaching.  Now, as I prepare my 748th post, I am thinking about how I can organize my posts to make them findable and useful to the reader who visits and browses herein.

One thing that I have recently done is to update the blog's searchability -- 
in the right column you will find a search box.  

If you enter a term like "math" into the box, the search finds most of the posts in the entire blog and is thus not very helpful -- but you might try the term "triangle" and you would find about 20 relevant posts; one of them (from October 13, 2010) has the title "Varieties of triangles -- by Guillevic" and is the most-visited entry herein.  If you are, like me, someone who looks for math publicity and opportunities for girls, you may choose to enter "girl" in the search box.  This search, too, will lead to about 20 postings. 

Which hat? (from Slovenia)

     For a long time I have highly valued the work of Eastern European poets -- including Wislawa Szymborska, Miroslav Holub, Nichita Stanescu, Nina Cassian -- and have been pleased to find mathematical imagery in their work.  Early in November I had the privilege of attending a reading at the Goethe-Institut Washington that featured Slovenian poet Aleš Šteger -- born in 1973, winner of many awards, and described as the most translated Slovenian author of his generation.  A fun event -- from which I give you one of his slightly-mathematical offerings.

Are we speaking of "mathematics" or "poetry"?

     This week started with the excitement of an email message from Evelyn Lamb with a link to her Scientific American blog where she created a fun-to-take online poetry-math quiz based on an idea of mine (first published in 1992):

Can you tell the difference between mathematics and poetry?

Here’s a link to a SCIENTIFIC AMERICAN quiz to help you decide?

And a couple of centuries ago there was William Wordsworth -- who also contemplated both poetry and mathematics:

               On poetry and geometric truth
               and their high privilege of lasting life,
               From all internal injury exempt,
               I mused; upon these chiefly:  and at length,
               My senses yielding to the sultry air,
               Sleep seized me, and I passed into a dream.

William Wordsworth (1770-1850)

The Prelude, Book 5

Sustainability needs the arts AND mathematics . . .

The following poem is by Erica Jolly -- an Australian poet and retired teacher who is working hard to have the arts and the sciences integrated in Australian schools curricula.  “For too long, since the 1950s, we have witnessed serious losses across disciplines as science and mathematics have been deliberately separated from the arts and humanities,” Ms Jolly says.

Thanksgiving, 2015

Thinking toward Thanksgiving Day tomorrow, I am grateful for  --

 in addition to my children and grandchildren who will gather --

 all of the mathematic and poetic voices that help me see our world.
 Happy Thanksgiving wishes for all who read here!

Quoting Isaac Newton . . . . a "found" poem

     I do not know what
     I may appear to the world;
     but to myself I seem to have been
     only like a boy playing on the seashore,
     and diverting myself now and then
     finding a smoother pebble
     or a prettier shell than ordinary,
     whilst the great ocean of truth
     lay all undiscovered before me.

   -Isaac Newton, philosopher and mathematician (1642-1727)
