An alert to today's poem came from Greg Coxson, a University of Wisconsin-educated, Silver Spring-based, radar engineer who loves mathematics and poetry. The poem is by Howard Nemerov (1920-1991) and it builds to a presentation of its perfect mathematical image near its end.

Immense polygons of evening
Sometimes one wonderful line makes me fall in love with a poem. I offer the following -- in which the title first draws me in and then "immense polygons of evening" delights me even more. Here, by Paula Closson Buck, is "A Betrayal of Integers," which uses mathematical terminology as the perfect mix of seasonings for a gourmet dish.

Counting rhymes -- Catalan, Bell numbers
In mathematics, the Catalan numbers (named for Belgian mathematician Eugène Charles Catalan, 1814–1894, and beginning with 1, 1, 2, 5, 14, 42, 132, 429, . . . ) and the Bell numbers (named for the Scottish mathematician Eric Temple Bell, 1883-1960, and beginning with 1, 1, 2, 5, 15, 52, 203, 877, . . . ), provide answers to a variety of mathematical counting-problems, including counting the number of rhyme schemes for stanzas of poetry. In English, earliest classification of rhyme schemes dates back to George Puttenham and his treatise, The Arte of English Poesie (published around 1590).

Poems of set paradox and spatial dimension
Universal Paradox by Sandra DeLozier Coleman
One gigantic set made of all that there is
Boggles the mind with paradoxes.
For it is greater than all, but smaller than this —
The set which consists of the subsets of it.

Black History Month -- celebrate Haynes and Hughes
Living on the border of Washington DC I am exposed to items of local history for our nation's capital. One such item involves the "discovery" of Langston Hughes (1902-1967) by poet Vachel Lindsay (1879 - 1931) at the Marriott Wardman Park Hotel, a leading conference hotel in the city. A second story is a mathematical one. Martha Euphnemia Lofton Haynes (1890-1980), a fourth-generation Washingtonian, was the first black woman to earn a PhD in mathematics -- conferred in 1943 by Catholic University.

Srinivasa Ramanujan
One of the most intriguing tales in the modern history of mathematics involves Indian-born mathematician and genius Srinivasa Ramanujan (1887-1920) who traveled to England to work with G H Hardy (1877-1947). Poet Jonathan Holden, who writes often of matters mathematical, offers this portrait of the Indian prodigy:

The question of what it means to think is never far from my focus -- and is particularly on my mind during these days that the computer Watson is competing on the TV game show, Jeopardy. Here is a poem I like a lot -- "New Math" by Cole Swensen -- in which the poet (writing more than 20 years ago) considers the limits of computation (and whether it could aid persons unable to recognize faces).

How much math does a math-poem need?
Poems offered in this blog vary in the levels of mathematics they contain. One mathematical reader commented privately that in some of the poems the use of mathematical terms is "purely decorative." Indeed, some people have particular expectations for poetry that relates to mathematics -- they want the content to use mathematical notation or to present a mathematical truth. Such as, perhaps, this abbreviated statement of the four-color theorem (formulated as a 4x4 square):

Electronic poetry -- Stephanie Strickland
Computers offer new opportunities for poetry -- permitting new types of poems. Animated perhaps, or hypertext, or vast manuscripts of which we can see at most a fragment -- the possibilities are many. Stephanie Strickland is one of the pioneers of electronic literature -- and this post was sparked by my experiences at her presentations at Georgetown University on February 1.

AWP avoids mathematics
I am currently attending the 2011 AWP* Conference and am disappointed that none of the sessions involves connections of writing with mathematics -- this disappointment has prodded me to write the Fib that I include below. (Recall that a Fib is a poem whose successive line-syllable counts follow the **Fibonacci seqence -- the numbers that count the petals on a flower, the spirals of seedheads on a pine cone or pineapple, and many other natural things.)

Painting tragedy with numbers
Although words such as "massacre" and "victim" and "buried" help us to understand the effects of disaster and injustice, sometimes the most vivid descriptions of horrific events are painted with numbers -- 6 million slain, 4-year-old girl raped, 11 days without food. One of the strong poetic voices of the twentieth century was June Jordan (1936-2002). Works in her collection, Kissing God Goodbye (Anchor Books, 1997), speak out for all victims, in Baghdad or Belfast, in Lebanon or Algeria. In the following poem from that 1997 collection, Jordan uses numbers to heighten her portrayal of tragedy in Bosnia.

Romanian poets -- Cassian and Barbu
Born in 1924, in Galati, Romania, Nina Cassian has published over fifty books -- besides poetry, she has works of fiction and books for children. Since 1985 she has lived in exile in the United States. Among those Cassian credits with strong influences on her poetry is mathematician / poet Dan Barbilian / Ion Barbu (1895-1961). This poem by Cassian illustrates those mathematical influences:

Poem and parody -- isomorphic?
In mathematics, algebraic systems that have different objects but the same structure are described as isomorphic. The parody in poetry illustrates the same idea -- a new poem is created that matches the form of a chosen poem, but uses different words. For example, here are the opening stanzas of a poem published in 1799 by Robert Southey (1777-1843) that was later parodied by Lewis Carroll (1832-1898) in Alice's Adventures in Wonderland.

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.

Which are "real" numbers?
The adjective "real" in the term "real number" causes confusion for many whose mathematics is casual rather than intense. I like the mathematical definition of a number as real iff it corresponds to a point on the number line -- for this gives the abstract number a geometric counterpart (an attachment to reality) -- but there are others for whom the reality of a number depends on its emotional connections, perhaps used in ways that poet Ginger Andrews uses numbers in the following poem.

An Elegy from Argentina
Mathematicians are mourning the too-soon death of Cora Sadosky (1940-2010) on December 3. Born in Argentina, Sadosky earned her doctoral degree at the University of Chicago in 1965 and published more than fifty papers in harmonic analysis and operator theory. A strong advocate for women in mathematics (1993-95 president of AWM) and active in promoting greater participation of African-Americans in mathematics, Sadosky was a long-time faculty member at Howard University.
Here, in recognition of the contributions of Cora Sadosky, is "An Elegy" by Argentinian poet Mirta Rosenberg. Using Rosenberg's words for her mother, we celebrate a foremother in mathematics:

Poet Lucia Perillo was honored Monday evening, December 13 at the Library of Congress -- as her collection Inseminating the Elephant won the 2010 Bobbit National Prize for Poetry. It was my good fortune to be there to hear her read. She is direct and upretentious, tough and witty. An evening of good poetry read well. Perillo has an undergraduate degree in wildlife management and her deep understandings of the natural world are evident in her poems.

Are all mathematicians equal?
My first posting for this blog (on March 23, 2010) featured one of my earliest poems, a tribute to mathematician Emmy Noether (1882 -1935) entitled "My Dance Is Mathematics." Even as it praised Noether's achievements, the poem protested the secondary status of math-women, not only in Noether's day but also today. It ends with the stanza :
Today, history books proclaim that Noether
is the greatest mathematician
her sex has produced. They say she was good
for a woman.

A melon strolling on two tendrils.

Money's new minted in this fat purse.
I'm a means, a stage, a cow in calf.
I've eaten a bag of green apples,
Boarded the train there's no getting off.
This 9 x 9 square first appeared in Crossing the Water (Faber and Faber, 1971).

Butterfly Effects
An equation or system of equations is said to be "ill-conditioned" if a small change in input data can produce a very large change in the output. This inverse relationship between input and output has become popularly known by the phrase "butterfly effect." Two poets from Eastern Pennsylvania, Gary Fincke and Harry Humes, have written poems about this phenomenon.

Syllable-Sestina -- a square permutation poem
Some poetry is "free verse" but many poems are crafted by following some sort of form or constraint--they might be sonnets or ballads or pantoums or squares, or possibly even a newly invented form. From poet Tiel Aisha Ansari I learned of a "syllable sestina challenge" from Wag's Revue. The desired poem contains six lines and only six syllables, which are repeated using the following permutation-pattern (the same pattern followed by the end-words in the stanzas of a sestina):

Celebrate Constraints -- Happy Birthday, OULIPO
Patrick Bahls and Richard Chess of the University of North Carolina at Ashville have organized a "Conference on Constrained Poetry" to be held on November 19-20 in celebration of the 50th Anniversary of OULIPO (short for French: OUvroir de LIttérature POtentielle), founded in 1960 by Raymond Queneau and François Le Lionnais. The group defines the term littérature potentielle as (rough translation): "the seeking of new structures and patterns that may be used by writers in any way they enjoy." Constraints are used to trigger new ideas and the Oulipo group is an ongoing source of novel techniques, often based on mathematical ideas -- such as counting letters and syllables, substitution algorithms, permutations, palindromes, and even chess problems.

Special square stanzas
My recent posting (November 14) of a symmetric stanza by Lewis Carroll illustrates one variety of "square" poem -- in which the number of words per line is the same as the number of lines. My own square poems (for examples, see October 7 or June 9) are syllable-squares; that is, each stanza has the same number of syllables per line as there are lines. Lisa McCool's poem below is, like Carroll's, a word-square; in McCool's poem -- in addition to the 6x6 shape -- the first words of each line, when read down, match the first line of the poem, and the last words of each line, when read down, match the last line of the poem.

Symmetric stanza
Although the following stanza by mathematician-author Lewis Carroll first appears to be a merely melodramatic example of Victorian verse, a bit of scrutiny reveals its special symmetry.
I often wondered when I cursed,
Often feared where I would be—
Wondered where she’d yield her love
When I yield, so will she,
I would her will be pitied!
Cursed be love! She pitied me…
This 6 line stanza by Carroll (well-known for for his nonsense verse) reads the same both horizontally and vertically.
I often wondered when I cursed,
Often feared where I would be—
Wondered where she’d yield her love
When I yield, so will she,
I would her will be pitied!
Cursed be love! She pitied me…

Theorem-proof / Cut-up / poems
For mathematicians, reading a well-crafted proof that turns toward its conclusion with elegance and perhaps surprise -- this mirrors an encounter with poetry. But can one have that poetry-math experience without being fluent in the language of mathematics? Below I offer a proof (a version of Euclid's proof of the infinitude of primes) and a "cut-up" produced from that proof-- and I invite readers (both mathematical and non-mathematical) to consider them as poems.

One type of "mathematical" poetry
When I began (in the 1980s) collecting examples of "mathematical poetry," I sought lines of verse that included some mathematical terminology. More recently, my view has expanded to include structual, visual, and algorithmic influcences from mathematics; however, the two samples from the work of William Blake (1757-1827), presented below, fit into that initial category -- selected as "mathematical" because of their vocabulary -- one speaks of "infinity," the other of "symmetry." (Blake was an artist as well as poet and his volumes of poetry were illustrated with his prints.) The following stanza is the opening quatrain for Blake's poem "Auguries of Innocence."

Troubles with math, expressed poetically
Should I admit that I sometimes feel a bit of resentment toward people who are insistently articulate about their difficulties with mathematics? As if that good energy might be turned toward learning the subject they decry.
On the whole, though, it seems better to face the fact that we folks who speak the language of mathematics are the odd ones. Here are perceptive trouble-with-math poems by John Stone (1936-2008), who wrote as a parent trying to help with homework, and Elizabeth Savage, who compares a pair of differently-able friends.

Creation from "nothing"
Christian Otto Josef Wolfgang Morgenstern (1871-1914) was a German writer whose poetry often involved paradox or nonsense and whose witticisms are oft-quoted by his German admirers; for example, the following line from "The Impossible Fact" ("Die unmögliche Tatsache", 1910): "Weil, so schließt er messerscharf / Nicht sein kann, was nicht sein darf." which may be translated as "For, he reasons pointedly / That which must not, can not be."

The Fib -- a form that gathers strength
The "Fib" is a poetry form in which the numbers of syllables per line follow the pattern of the Fibonacci numbers. (See also April 19 and April 29 postings.) The sequence of Fibonacci numbers starts with 0 and 1 and then each successive Fibonacci number is the sum of the two preceding. Thus, the non-zero members of the sequence are:
1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, . . .
Poet Athena Kildegaard's collection Red Momentum (Red Dragonfly Press, 2006 ) consists entirely of Fibonacci poems. The following samples from Kildegaard's collection illustrate the way that increasing line lengths can build to dramatic effect. From a simple start, complexity grows.

Continuing Climate Concerns
Split This Rock, an activist confederation of poets concerned with vital human issues, has directed attention to environmental concerns by publishing my "Mitigation of Toxins" as their poem of the week for this final week in October; please follow the link and enjoy this poem and others their archive offers. ("Mitigation of Toxins" first appeared in Innisfree and also is included in my new collection, Red Has No Reason .)
In continued support of climate concerns--which seem to me often to fit a square-poem format -- here is "Arctic," a 5x5 square by poet Linda Benninghoff, author of six chapbook collections.

A Lemma by Constance Reid
Constance Reid (1918-2010), died on October 14. Sister of a mathematician (Julia Robinson), Reid wrote first about life in World War II factories that supported the war effort and then, later, several biographies (including one of her sister) and other books about mathematics. Kenneth Rexroth's poem "A Lemma by Constance Reid" (offered below) is based on material appearing in Reid's popular book From Zero to Infinity: What Makes Numbers Interesting (Thomas Y Crowell, 1955). Reid is known for the enthusiasm and clarity with which she presented mathematical ideas--seeking to attract and to satisfy non-mathematical readers.

In an article about the Chilean mathematician and poet Nicanor Parra, Paul M Pearson says, : "Parra almost wrote poetry like he would a mathematical theorem using an extreme 'economy of language' with 'no metaphors, no literary figures.' " Today I present work by Nicanor Parra and Richard Aston, both of whom write their poetry with the same economy and care that are used when writing mathematics.

I miss you, Martin Gardner
Martin Gardner (1914-2010), featured also in my June 6 posting, would have been 96 years old today--October 21, 2010. All over the world lovers of mathematical puzzles have taken time today to celebrate Gardner's puzzling--and the ways it stimulated their own. Although Gardner disclaimed poetic gifts, he popularized puzzle poems written by others -- and he introduced the poetry strategies of the OULIPO (see March 25, August 5, and August 23 postings) to American readers. Here is a puzzle poem, by an unknown author, included in Gardner's Puzzles from Other Worlds (Vintage, 1984) and in Strange Attractors (A K Peters, 2008).

Giraffe -- novel (& prose poem) by May Swenson
Poet and playright May Swenson (1913-89) was born in Utah to Mormon parents and grew up in a home in which Swedish was the primary language. Swenson wrote of the experience of poetry as "based in a craving to get through the curtains of things as they appear, to things as they are, and then into the larger, wilder space of things as they are becoming." Here are the opening stanzas of Swenson's prose poem, "GIRAFFE: A Novel," from In Other Words: New Poems (Knopf, 1987). I think this is FUN -- and hope you also enjoy it.

The Length of a Coastline
In the nineties, fifteen or so years ago, when I began posting mathematical poems on the Internet, two of my earliest connections were Ken Stange, a poet and polymath and professor of psychology at Ontario's Nipissing University, and his daughter Kate, then a teen. Kate publicized her love of mathematics and poetry by creating an online collection,"Mathematical Poetry: A Small Anthology" which she has continued to maintain for many years--during which she has completed undergraduate and graduate studies in mathematics.

Voices in a Geometry Classroom
I have been invited to return next week (October 20 at 7 PM) to Bloomsburg University, where I taught mathematics for lots of years, for a poetry reading. Preparation for the reading (which celebrates my new book, Red Has No Reason) drew my thinking back to my teaching days at Bloom and to "Geometry Demonstration," a poem about the arguments in my head as I faced a particularly challenging class of geometry students. Here it is.

Varieties of triangles -- by Guillevic
My introduction to French poet Guillevic (1909-97) came from UK poet Tim Love who found three of his triangle poems translated into Italian. Jacqueline Lapidus translated them for me from French into English, after which I also found Guillevic's collection Geometries (Englished by Richard Sieburth, Ugly Duckling Presse, 2010) -- with its circles, ellipses, parallels, and so on. And so, beyond these three, there will be more to enjoy later.

Varieties of palindromes in poetry
My posting for October 6 mentioned palindromes. Today we continue with the topic, including illustrations of the various ways they may influence poems. A number such as 12345654321, which reads the same if its digits are reversed, is the sort of palindrome one encounters in arithmetic. Palindromic poetry includes more variety. These sentences, taken from a list compiled by Ralph Griswold, are samples of palindromes in which the unit is a single letter.

"The Seventh" by Attila Jozsef
Attila József (1905-1937) is one of the most important Hungarian poets of the 20th century.
The Seventh by Attila József
If you set foot on this earth,
you must go through seven births.
Once, in a house that's burning,
once, among ice floes churning,
once, amidst madmen raving,
once, in a field of wheat swaying,
once, in a cloister, bells ringing,
once, in a pigsty a-squealing.
Six babes crying, not enough, son.
Let yourself be the seventh one.

"Poetry, in other words, is mathematics"
From Tim Love, British poet and member of the Computer Systems Group in the Engineering Department at Cambridge University, I received this link -- National Poetry Day: unlock the mathematical secrets of verse -- to an article announcing the October 7 holiday in the UK. The article's author, Steve Jones (a professor of genetics at University College), goes so far as to begin his third paragraph with the sentence quoted as title to this posting. Follow the link and form your own view. Is mathematics truly important to poetry?

Nursing--and other vital applications of counting
Although counting is one of the basic activities of mathematics, its importance also extends to the highest mathematical levels. We count the solutions to systems of equations, the crossings in a diagram of a knot, the intersections of surfaces in multi-dimensional space, the necessary repititions in a circuit covering the edges of a graph. Counting likewise imposes order on some of life's difficult and non-mathematical tasks. In Veneta Masson's poem, "Arithmetic of Nurses," we have a vivid picture of the careful alertness required of those who cares for ill patients.
Following Masson's poem, is "Things to Count On," one of my own poems of counting--a prose poem describing the way that numbers order the life of a frugal farmer and his family, working to make ends meet in Pennsylvania in the middle of the 20th century.

Is mathematics discovered -- or invented?
The issue of whether mathematics is invented or discovered is posed often. Less frequently, queries as to where poetry falls in these categories. Perhaps individual answers to these questions depend on how each of us, from the inside, views the workings of the mind. Here we have, from poet (and math teacher) Amy Uyematsu,"The Invention of Mathematics."

Ideal Geometry -- complex politics
Christopher Morley (1890-1957) was an American poet, novelist, and publisher who was the son of a poet and musician (Lilian Janet Bird) and a mathematics professor (Frank Morley) at Haverford College. His "Sonnet by a Geometer," below, is written in the voice of a circle and compares mathematical perfection with human imperfection. For us who read the poem 90 years after its writing, Morley's phrase in line 13 -- "They talk of 14 points" -- is puzzling at first.

Reflections on the Transfinite
Georg Cantor (1845-1918), a German mathematician, first dared to think the counter-intuitive notion that not all infinite sets have the same size--and then he proved it: The set of all real numbers (including all of the decimal numbers representable on the number line) cannot be matched in a one-to-one pairing with the set of counting (or natural) numbers -- 1,2,3,4, . . . . Sets whose elements can be matched one-to-one with the counting numbers are termed "countable" -- and Cantor's result showed that the set of all real numbers is uncountable.
Cantor developed an extensive theory of transfinite numbers -- and poet (as well as philosopher and professor) Emily Grosholz reflects on these in a poem:

Goldbach's conjecture -- easily stated but unsolved
This blog's July 20 posting featured work from poets who have spouses or siblings who are mathematicians. Today, introducing the work of Michele Battiste (who considers Goldbach's conjecture), we again honor that theme. Goldbach's conjecture asserts that every even integer greater than 2 can be expressed as a sum of two prime integers. For example, 4 = 2 + 2, 6 = 3 + 3, 8 = 3 + 5, 10 = 7 + 3 or 5 + 5, and so on. The conjecture was first proposed in 1742 by German mathematican Christian Goldbach in a letter to Swiss mathematician Leonhard Euler -- and in 2010--though it has been verified for many, many, many even integers--it still remains unproved.

The Magic of Numbers -- Kenneth Koch
I first became acquainted with Kenneth Koch (1925-2002) through his small and hugely valuable paperback of teaching strategies, Wishes, Lies, and Dreams: Teaching Children to Write Poetry. Later, searching for poems about trains, I stumbled upon "One Train May Hide Another" -- which I return to again and again for its wise beauty. Today I present, for our reflection, Koch's poem, "The Magic of Numbers." Enjoy.

Prisoner's Dilemma -- and permutations
In game theory's original, single-play, Prisoner's Dilemma problem, two prisoners each are given the choice between silence and betrayal of the other. The optimal choice is betrayal -- and therein lies a paradox.

Ghosts of Departed Quantities
Years ago in calculus class I excitedly learned that an infinite number of terms may have a finite sum. Manipulation of infinities seems somewhat routine to me now but my early ideas of calculus enlarged me a thousand-fold. Algebra was a language, geometry was a world-view, and calculus was a big idea. Like any big idea, even though it had been hundreds of years in formation, it met with resistance. In 1764 Bishop George Berkeley attacked the logical foundations of the calculus that Isaac Newton had unified. Here, from the online mathematics magazine plus, is a description of the attack.

Rhymes help to remember the digits of Pi
Calculated at the website, WolframAlpha, here are the first fifty-nine digits of the irrational number π (ratio of a circle's circumference to its diameter):
π = 3.1415926535897932384626433832795028841971693993751058209749...
Before computers became available to calculate π to lots of decimal places in an instant, people who did scientific calculations could keep the number easily available by memorizing some of the digits. The website fun-with-words offers several mnemonics for π , the most common type being a word-length mnemonic in which the number of letters in each word corresponds to a digit. For example the sentence, "How I wish I could calculate pi," gives us the first seven digits.
