Found at Komplexify.com, a variety of (often-amusing) mathematical verses -- including a collection of Error Message Haiku. Approaching a New Year, I have been reflecting on my device-dependencies and considering resolutions about them -- and musing over some of these wistful substitutions for machine messages I dread:

A crash reduces

Your expensive computer

To a simple stone.

Chaos reigns within.

Reflect, repent, and reboot.

Order shall return.

### 13 lads of Christmas

In addition to waterfalls and geysers and the Aurora, Iceland has outstanding museums. On the morning of December 10, I visited the National Museum of Iceland in Reykjavik -- and enjoyed a careful introduction to the history of this fascinating and friendly nation. Something I missed, however, was seeing one of the 13 Yuletide Lads that are an Icelandic tradition and who visit the Museum one-by-one on the 13 days before Christmas, each wearing
traditional costume and trying to pilfer the goodies he
likes best.

### Iceland -- poetry, stones

British translator and editor David McDuff blogs at "Nordic Voices in Print" -- a site that he uses as "a way of making some of my translations of Nordic poetry and prose available online." Here is "stones" -- the third of a group of ten poems he has posted by Icelandic poet Sjón. This one involves a few numbers and I present it here as a math-poetry token of the fascinating land I am planning to visit: a five-day Iceland vacation adventure, traveling with my Eastern Village neighbors Priscilla and Glenn.

### Algebra cadabra

It was my good fortune to meet Colette Inez back in the early 1990s when she was poet-in-residence at Bucknell University. Then, as now, I was collecting poems-with-mathematics, and I have long loved this poem that weaves figuring into forests.

We heard swifts feeding in air,

sparrows ruffling dusty feathers,

a tapping on stones, mud, snow, pulp

when rain came down, the hiss of fire.

Counting bird eggs in a dome of twigs,

we heard trees fall and learned

to name them on a page for school.

### A poet (math-daughter) speaks of math's beauty

I met Minnesota poet Roseann Lloyd when we served together on an AWP (Associated Writing Programs) conference panel on translation several years ago. There I was considering, as I so often am, the translation of mathematics into representations that poets understand. Roseann 's father was a mathematics professor and she learned early that "mathematics is its own beauty." And she has permitted me to offer you this poem.

Once Daddy enthralled his students at SMS --

handsome in his navy blue suit and dusty hands,

chalk clicking out equations lickety-split.

A third-grader, I waited for him every day

in the cool marble hall. Listened to the rhythm

of the chalk on the board. Even then I knew

that pure math is an art equal to music, second

only to poetry in the realm of beauty.

Even as the finite encloses an infinite series

And in the unlimited limits appear,

So the soul of immensity dwells in minutia

And in narrowest limits no limits inhere.

What joy to discern the minute in infinity!

The vast to perceive in the small, what divinity!

### Neruda speaks of numeration

The collection, Late and Posthumous Poems, 1968-1974 (Grove Press, 1988) by Chilean Nobelist Pablo Neruda (1904-1973) offers to readers a collection of Neruda's later work, ably translated by Ben Belitt. Here is a poem that explores the vast world opened by the invention of numeration.

A hand made the number.

It joined one little stone

to another, one thunderclap

to another,

one fallen eagle

to another, one

arrowhead to another,

and then with the patience of granite

the hand

made a double incision, two wounds,

and two grooves: and a

number was born.

*Uneasy Relations*by mathematician-poet Michael Bartholomew-Biggs is concerned with similarities and differences between mathematical and poetic cultures -- a topic of immense interest also to me and one that I too try to address in my verse. I wonder -- HOW can I show non-mathematicians that good mathematics is poetry??!! And, moreover, how can I (mostly a mathematician) write (as advocated by Wallace Stevens and agreed with by other poets) of things rather than (as mathematics wants) of ideas. OR, may one make poetry of ideas?**Two Cultures**by Michael Bartholomew-Biggs**Graves claimed there isn't**

### Topology for poets

The title of this posting ("Topology for Poets") comes from Maryland Poet Amy Eisner's poem "Lure" (offered below) -- a poem that plays with math concepts. (In mathematics, "topology" is a variant of geometry in two shapes are "equivalent" if one could be obtained from the other by stretching or bending.)

It was my pleasure to meet Amy when she read in the Takoma Park Third Thursday Poetry Series earlier this year. I like her work. Enjoy!

My friend is crocheting a fishing line. This is not a gift and keeps no one warm.

This is withdrawing. Persisting in a flaw. Forfending.

She knows there’s something perverse in it. Like growing a mold garden.

Fishing does involve a hook, a line, and a net. But not like this.

### Mathematics of love . . .

"Mathematics of Love" is the title poem of a collection by John Edwin Cohen (1941-2012), published in 2011 by Anaphora Literary Press and presented here with press permission. Cohen has used mathematics playfully and does what a mathematician never dares to do, use a mathematical term with other than its precise meaning. Still, perhaps, even math folks may enjoy this application of geometric shape and poetic license!

In my post for 6 September 2013 I presented Oulipian Harry Mathews' poem "Multiple Choice" -- a poem whose alternative story lines might be represented by a tree diagram. That poem was but one of 29 variations (or "Exercises in Style") by Harry Mathews as he retold again and again a tale first offered by lute-player and composer John Dowland (1563-1626), a musician whose work still finds audience today. Here is Dowland's tale, from which Matthews created 29 alternative versions. (See "Trial Impressions" in

Yesterday afternoon, at the Goethe Institut in Washington DC, I saw a wonderful film, "Measuring the World." Based on a popular 2005 novel by Daniel Kehlmann, the story of a friendship between preeminent German mathematician Carl Friedrich Gauss (1777-1855) and Prussian naturalist Alexander von Humboldt (1769-1859). The film offers a delightful interplay of personalities and ideas as it darts between the explorations of these two men -- one digging inside his head for mathematics and the other traveling over mountains, through jungles, across oceans.

### A poet re-envisions space

University of Pennsylvania professor Robert Ghrist, in his September 19 lecture ("Putting Topology to Work") at the MAA's Carriage House, credited poet John Milton (1608-1674) with the first use of the word

*as an abstract entity -- and, Ghrist asserted, by so doing, Milton opened a door to the study of abstract space (known in mathematics as***space***).***topology**
The following material is a 24 September correction

from my 23 September posting. For I discovered -- in a thoughtful email from Ghrist --

that the proper citation of "space" was not from line 50 of Book 1 but from line 89 of Book 7.

(I invite you go to Project Gutenberg for

*Paradise Lost*in its entirety.)
Here, below, I have replaced my original posting of lines 44-74 of Book 1

with lines 80 - 97 of Book 7 -- lines taken from my shelf copy of Milton's

*Paradise Lost*,
the 1968 Signet Classic Edition, edited by Christopher Ricks.

In the selection below and throughout his epic, Milton replaces past visions of hell down-in-the-earth and heaven up-in-the-sky with more complex and abstract configurations.

### Consider Pascal

Mathematician Blaise Pascal (France, 1623-1662) is known for his explorations with computing machines, for his ideas concerning probabilities, for trying to make rational a decision to believe in God and eternal life, for his explorations of the cycloid and the limacon (curves generated by rolling circles) and a host of other topics.

I was introduced to Melbourne poet, novelist, and mathematician (he teaches at Victoria University of Technology), Tom Petsinis by South-African editor of Poetry-International, Liesl Jobson. Here from Petsinis' collection,

In 1999, in

*Infinite Abelian Groups*-- it was one of my texts for a graduate seminar (with Gene Levy) at the University of Oklahoma in the 1960s. Later I knew Kaplansky as a songwriter, author of new lyrics for "That's Entertainment." Kaplansky's adaptation, "That's Mathematics," dedicated to his former student, math-musician-songwriter Tom Lehrer, and to his daughter, singer Lucy Kaplansky, is given below.In 1999, in

*Science News*, writer Ivars Peterson (now Director of Publications for the MAA -- Mathematical Association of America) wrote an article about Kaplansky's songwriting in which he mentions his daughter, Lucy Kaplansky, a singer who frequently performs her father's songs. A YouTube recording of Lucy singing "The Song of Pi" (in which there is a correspondence between musical notes and the first fourteen digits of pi) is available here.

A time to catch up with old friends -- River Poets Dave Barsky, Carol Ann Heckman, and Janet Locke, and Wilkes-Barre poet Richard Aston. Poets and musicians featured at the festival included Lester Hirsh, Pamela Kavanaugh, James Pingry, Doug McMinn, Jack Troy, Julia Spicher Kasdorf, and Sheryl St. Germain.

The theme at Stillwater was Nature/Agriculture and my 5 August post included poems from conference organizer Clark and featured reader Kasdorf -- poems that involved both nature and mathematics. Although found in Kasdorf's opening poem, "Double the Digits," mathematics was scarce. Sheryl St. Germain, the final reader (currently a Pittsburgher, transplanted from New Orleans) briefly mentions computation and measurement in her "Hurricane Season ." The full poem is available through St Germain's website; here is one of its stanzas.

### Mathematical structure and Multiple choice

A sonnet repeats the iambic rhythm of the heart beat (da-DUM, da-DUM, . . .) with a line length corresponding to a typical breath (5 heartbeats); it thus seems easy to internalize the numerical structure that guides such a poem.

A decision tree offers a very different choice of mathematical structure for a poem -- displaying for a reader different choices among stanzas. Originally proposed to the OULIPO by founder Francois Le Lionnais, and referred to as a multiple-choice narrative, such a structure allows readers of a poem to choose among subsequent events. Instead of reading the poem vertically, we may jump about, choosing the sequence we want to read.

### A square-root of dead weight . . .

A poet I love (Seamus Heaney, 1939-2013, 1995 Nobelist) has died. The NYTimes obituary for Heaney quotes one of my favorites of his poems, "Digging" -- also available at poetryfoundation.org. Part of what I like about this Irishman's poetry is its design. Not only do his poems offer musicality of language but they feel carefully constructed -- modeling real world phenomena as mathematical models do -- built with careful attention to structure and detail until varied factors have been erected into in integrated whole. "Digging" ties together the physical activity of Heaney's father shoveling in the peat bogs of Ireland to his own probing with a pen for words.

### Poetry in a math text

In the 1980s, all students at Bloomsburg University were required to take at least one mathematics course and I worked with colleagues to develop a suitable offering -- one that did not require expertise in algebra but which emphasized problem-solving. Our course became "Mathematical Thinking" -- and I began to develop suitable materials -- eventually writing and publishing

Once upon a tree

I came across a time.

*Mathematics in Daily Life: Making Decisions and Solving Problems*(McGraw-Hill, 1986). Each of the twenty-two chapters of this textbook is introduced with a relevant quote. Chapter 11, "Visualizing the Structure of Information with a Tree Diagram," opens with two lines by one of my favorite poets, Theodore Roethke:Once upon a tree

### Celebrating a math-woman

**I am continually searching for poems that feature past and current math-women.**

**When you find one (or create one) I will be glad to have you send it along.**

The lunar crater L Herschel is named for astronomer Caroline Lucretia Herschel (1750-1848) -- and I have celebrated this math-woman earlier with two fine poems: "Letter from Caroline Herschel" by Siv Cedering , and "Planetarium" by Adrienne Rich. Now Herschel is the focus of a forthcoming book by poet Laura Long,

*The Eye of Caroline Herschel: A Life in Poems*, (Finishing Line Press, 2013). Here, from that collection, is "The Taste of Mathematics: Caroline Herschel at 31" -- this poem also appears, along with a note about the full collection, in the July 2013 issue of

Written while I was poet-in-residence at Klondike Gold Rush National Historical Park, (in Skagway), this poem draws on historical data from the park's library to paint a bleak picture of wealth and survival in those gold-mad days.

Seth has said that he was moved to write by the novel Alexander Pushkin's verse novel

*The Golden Gate*(Random House, 1986) by taking turns reading its sonnets aloud to each other. After several dozen aloud, I could hear the voice even when I read silently and I went on to finish alone. And I loved it. I have gone on to enjoy several more works by Seth -- none of them poems but all wonderful stories, well told.Seth has said that he was moved to write by the novel Alexander Pushkin's verse novel

*Eugene Onegin*noted here on 10 August 2013 -- a novel of interest to mathematicians because of its link to Markov Chains. Seth's novel (reviewed here) also was made into an opera. These first two stanzas -- each containing the numbers 26 and 1980 -- introduce the novel's computer-guy, John:

### Pushkin poetry, Markov chains

A Markov chain is a mathematical process that can be used to answer questions such as these:

If the current letter I am reading is a vowel, what is the probability

that the next letter will be a vowel? A consonant?

Answers from these may be combined to create more lengthy predictions -- about the 3rd letter after a given one, or the 10th -- and so on.

A recent article by Brian Hayes in

If the current letter I am reading is a vowel, what is the probability

that the next letter will be a vowel? A consonant?

Answers from these may be combined to create more lengthy predictions -- about the 3rd letter after a given one, or the 10th -- and so on.

A recent article by Brian Hayes in

*American Scientist*(brought to my attention by Greg Coxson) alerted me to the fact that it is 100 years since the Russian mathematician A. A. Markov (1856 - 1922) announced his findings about these transition probabilities -- and, moreover, his work was based on analysis of poetry; the poetry was*Eugene Onegin*, a verse-novel in iambic tetrameter by Alexander Pushkin (1799-1837). Markov's analyis dealt with Pushkin's novel as a long string of alphabetic characters and he tabulated the categories of vowels and consonants for about 20,000 letters. (For a host of details, visit Hayes' careful and interesting article.)## Wednesday, August 7, 2013

### Feynman Point poems

The Feynman Point is a sequence of six 9s that occurs in the decimal expansion of π -- these 9s are found in positions 762 - 767 following the decimal point. When writing in Pilish (using word-lengths that correspond to digits of π), the Feynman Point offers a particular challenge since 9-letter words are infrequent. I learned about the Feynman Point here. AND I found a splendid database that makes the difficult task of choosing 6 9-letter words easily doable. Here is my first Feynman Point poem:

Scratchers sleepwalk --

seriously screening sentences,

slantwise.

Mike Keith's Pilish short story, Cadeic Cadenza, has this Feynman Point:

### Nursery Rhyme Mathematics

During the last week of July I was in California, vacationing with family (including six of my grandchildren). Most of these kids have grown past a fascination with nursery rhymes, but I still like them -- and think it's likely that memorization of rhymes helps with learning to read and count.

Another poem, "The Seventh Sense, " moves from a similar beginning " . . . none speak of the seventh" into a dreamy apprehension of the magical possibilities of items not yet classified. The following selection from*Zero*, "Triskaidekaphobia," offers remedies for the fear of bad luck brought by 13.

### A poem with two numbers

My friend Carol Ann Heckman has studied with Denise Levertov and feeds voraciously on her work. For many years I have loved Levertov's "The Secret" and today, rereading an email from Carol Ann, I went looking for a mathy poem by this beloved poet. I found the following -- with two numbers (and a hint of recursion):

A greyish bird

the size perhaps of two plump sparrows,

fallen in some field,

soon flattened, a dry

mess of feathers--

and no one knows

this was a prince among his kind,

virtuoso of virtuosos,

lord of a thousand songs,

debonair, elaborate in invention, fantasist,

rival of nightingales.

This poem rests on my bookshelf in Levertov's collection,

### Pool -- a game of geometry?

Years ago I taught a "liberal arts mathematics" course -- and for a time we used the text

*Mathematics, a Human Endeavor: A Textbook for Those Who Think They Don't Like the Subject*by Harold R. Jacobs (W H Freeman, 1971); the text's topics included one new to me, the geometry of the paths of billiard balls. The ease I found with this mathematics ill-prepared me for the skill I needed to avoid embarrassment at a neighbor's new pool table -- and the memories of it all drew me immediately into Dan Brown's poem, "Why I Never Applied Myself to Pool," found in the March 2013 issue of*Poetry*.**Why I Never Applied Myself to Pool**by Dan Brown

### Grandma got STEM

There are so many fine websites to visit and blogs to read that it is hard to get to them all. One of my recent pleasures has been Grandma Got STEM (STEM = Science, Technology, Engineering, Mathematics), orchestrated by Rachel Levy, Harvey Mudd College, Mathematics. Recent entries there that I've enjoyed are Martha Siegel (Towson University, Mathematics) and Carol Jo Crannell (mother of Annalisa Crannell, Franklin and Marshall College, Mathematics and Art).

For a while I wondered how I might link these STEM pioneers to poetry and this morning was delighted to discover in a bio of poet Mei-Mei Berssenbrugge that her Chinese mother was a mathematician. And these initial stanzas of Berssenbrugge's poem "Tan Tien" illustrate her familiarity with mathematical vocabulary.

### Miroslav Holub -- "what use is it?"

In earlier postings I have expressed my admiration for the Czech poet Miroslav Holub (1923-1998) -- a research scientist who also wrote fine poetry. In a biographical sketch of Holub at poetryfoundation.org, the poet is quoted as saying, " . . . I'm afraid that, if I had all the time in the world to write my poems, I would write nothing at all." There is no agreed standard for the amount of time to spend on a creative work. Many poets devote their full time to their craft; others fear over-writing and strictly limit their writing and editing. In each aspect of our lives it is possible to do too much or too little thinking about things. And so it goes.

My post on 5 April 2013 linked to several math-related Holub poems. And here is another; in "Magnetism," Holub focuses on the sometimes-silly, sometimes-practical, sometimes-too-limiting question often put to mathematics or science, "what use is it?"

Voting to select three favorite submissions will begin on July 15.

Here is an example (not the one I submitted, which begins "I go for Mars . . .").

Sometimes matching words to a syllable-count helps to bring focus to my musings. Here are two stanzas for which I used the Fibonacci numbers as lengths for the lines I built as I considered the continuing invisibility of most math-women.

### Balancing an Equation

I grew up on a farm and spent my middle life in a small town and now live in a city. A sort of immigrant. A farm girl who became a professor. A balancing act.

Some years back, one of my math department colleagues posted on his office door a quote from George Bernard Shaw (1856-1950) :

The reasonable man adapts himself to the world: the unreasonable one persists

in trying to adapt the world to himself. Therefore all progress depends

on the unreasonable man.

At one time I much agreed with the Shaw quote. Now (perhaps because I am older or because I now live near to Washington, DC and contentious party politics) I am more admiring of balance than unreasonableness. Here is a lovely poem by Caroline Caddy about balance and numbers.

### What is not possible?

It is impossible for a number to be greater than 2 if it is not greater than 1. It is impossible to find a rational number whose square is 2. Up to now it has not been possible to show that π is a normal number. Mathematicians like the challenge of the impossible. To challenge, to prove, to refute.

In the poem below Chelsea Martin devises an entertaining web of circular reasoning to explore the impossibility of eating at MacDonald's.

Eating food from McDonald's is mathematically impossible.

Because before you can eat it, you have to order it.

And before you can order it, you have to decide what you want.

And before you can decide what you want, you have to read the menu.

And before you can read the menu, you have to be in front of the menu.

And before you can be in front of the menu, you have to wait in line.

And before you can wait in line, you have to drive to the restaurant.

And before you can drive to the restaurant, you have to get in your car.

And before you can get in your car, you have to put clothes on.

In the poem below Chelsea Martin devises an entertaining web of circular reasoning to explore the impossibility of eating at MacDonald's.

**McDonalds Is Impossible**by Chelsea MartinEating food from McDonald's is mathematically impossible.

Because before you can eat it, you have to order it.

And before you can order it, you have to decide what you want.

And before you can drive to the restaurant, you have to get in your car.

And before you can get in your car, you have to put clothes on.
