Brief reflections on definitions of LINE . . .
Breathless length by JoAnne Growney
A LINE, said Euclid, lies evenly
with the points on itself --
that is, it’s straight –-
and Euclid did (as do my friends)
named points as its two ends.
The LINE of modern geometry
escapes these limits
and stretches to infinity.
Just as unbounded lines
of poetry.

Remembering Abraham Lincoln
Today -- April 14, 2015 -- marks the 150th birthday of the assassination of President Abraham Lincoln (1809 - 1865) and April 15 is the date on which he died. Lincoln loved poetry and trained his reasoning with Euclid's geometry. Here is a brief sample of his own poetry (found -- along with other samples -- at PoetryFoundation.org).
Abraham Lincoln by Abraham Lincoln
Abraham Lincoln
his hand and pen
he will be good but
god knows When
From my copy of Walt Whitman's Leaves of Grass (Signet Classics, 1955), from the section "Memories of Lincoln," I have copied these well-known and thoughtful (and non-mathematical) lines:

Twined Arcs, Defying Euclid
The English language has adopted into current usage many terms from other languages. French terms like coup de grace and haut monde have for many years been found in English dictionaries. Recently, computer terms such as bite and captcha and google have achieved widespread use. In addition, those of us who are fluent in the language of mathematics find that its terms sometimes offer a concise best way to describe a non-mathematical phenomenon.
Mathematician-poet Sarah Glaz weaves mathematical terms into her poem, "Departures in May" -- a poem that uses the language of geometry to vivify the presence of loss, death and other dark forces.
Departures in May by Sarah Glaz
Big things crush, inside the brain,
like plaster of Paris on stone;
a taste of splintered metal;
terra-cotta hardness of heart's desire.
Statues motionless
at railroad depots,
proclaim imitation as life.

In Praise of Fractals
Philosopher Emily Grosholz is also a poet -- a poet who often writes of mathematics. Tessellations Publishing has recently (2014) published her collection Proportions of the Heart: Poems that Play with Mathematics (with illustrations by Robert Fathauer) and she has given me permission to present one of the fine poems from that collection.

Fractal Geometry
Lee Felice Pinkas is one of the founding editors of cellpoems -- a poetry journal distributed via text message. I found her poem,"The Fractal Geometry of Nature" in the Winter/Spring 2009 Issue (vol.14, no 1) of Crab Orchard Review.
The Fractal Geometry of Nature by Lee Felice Pinkas
Most emphatically, I do not consider
the fractal point of view as a panacea. . .
--Benoit Mandelbrot (1924-2010)
Father of fractals, we were foolish
to expect a light-show from you,
hoping your speech would fold upon itself
and mimic patterns too complex for Euclid.

Homage to Euclid
In my preceding post (20 March 2014) Katharine Merow's poem tells of the new geometries
developed with variations of Euclid's Parallel Postulate.
Martin Dickinson's poem, on the other hand, tells of richness within Euclid's geometry.

visible to us, yet revealing something invisible—
invisible, yet real?

One geometry is not enough
Writer Katharine Merow is in the Publications Department of the Washington DC headquarters of the MAA (Mathematical Association of America) and she is one of the poets who participated in the "Reading of Poetry with Mathematics" at JMM in Baltimore last January. Here is the engaging poem Merow read at that event -- a poem that considers the 19th century development of new and "non-euclidean" geometries from variants of Euclid's fifth postulate, the so-called parallel postulate:

From order to chaos -- a sonnet
Fractals by Diana Der-Hovanessian
Euclid alone has looked on beauty bare
--Edna St. Vincent Millay
Euclid alone began to formulate
the relation of circle, plane and sphere
in equations making it quite clear
that symmetry is what we celebrate.

Lincoln and Euclid -- common notions
This afternoon I enjoyed the recently-released film, Lincoln -- appreciating Sally Fields as Mary Todd, Tommy Lee Jones as Thaddeus Stevens and (especially) Daniel Day-Lewis as Abraham Lincoln. An absorbing drama -- inspiring and also informative. With a slight mention of mathematics: in a film conversation with two-young telegraph operators, Lincoln reflected on his study of Euclid and shared with the young men the first of Euclid's common notions:
Things that are equal to the same thing are equal to each other.
Things that are equal to the same thing are equal to each other.

Finding fault with a sphere . . .
On November 9 I had the pleasure (hosted by Irina Mitrea and Maria Lorenz) of talking ("Thirteen Ways that Math and Poetry Connect") with the Math Club at Temple University and, on November 5, I visited Marion Cohen's "Mathematics in Literature" class at Arcadia University. THANKS for these good times.
This

to all those students
from Arcadia and Temple
who participated in "math-poetry" with me --
who held forth with sonnets, pantoums,
squares, snowballs, and Fibs --

that rests
on
math.
My Temple host, Irina Mitrea, and I share something else besides being women who love mathematics -- the Romanian poet, Nichita Stanescu (1933-83), is a favorite for both of us. My October 23 posting ("On the Life of Ptolemy") offered one of Sean Cotter's recently published translations of poems by Stanescu and below I include more Stanescu-via-Cotter -- namely, two of the ten sections of "An Argument with Euclid." These stanzas illustrate Stanescu at his best -- irreverently using mathematical terminology and expressing articulate anger at seen and unseen powers of oppression.

Geometry . . . a way of seeing
Today's poem is not only a fine work of art, it is also -- for me-- a doorway to memory. I first heard it in the poet's voice when he visited Bloomsburg University in the late 1980s, and I was alerted to the reading and to James Galvin's work by my most dear friend, BU Professor of English Ervene Gulley (1943-2008). Ervene had been a mathematics major as an undergraduate but moved on from abstract algebra to Shakespeare. Her compassion, her broad-seeing view, and her fierce logic served her well in the study and teaching of literature. And in friendship. I miss her daily. She, like Galvin, questioned life and probed its geometry.

An algorithm shapes a poem
Mathematics sometimes appears in poetry via patterns that follow the Fibonacci numbers. The pattern of Pascal's triangle also has been used. In her intriguing collection, Do the Math (Tupelo Press, 2008), poet Emily Galvin (now also a California attorney) uses these and more. Just as Euclid's Algorithm involves an interaction between two numbers, the following poem by Galvin applies the algorithm in a conversation between two voices.
Euclid's Algorithm by Emily Galvin
These ten scenes happen on the blank stage.
A and B could be any two people, so long as
they've been together for longer than either

Euclid meets Broadway
Several years ago while visiting my older son in Colorado Springs I also went to nearby Boulder where, driving along Broadway, I came to a street sign that made me gasp with delight. I was at the intersection of Broadway and Euclid. That fact, that suggestion of a merge of two worlds, needed to be part of a poem. Some time later I wrote:

Thoughts Suggested by a College Examination
Just when I was convinced that mathematical subject matter appears proportionately more in modern than in classical poetry, I turned again to work by Lord George Gordon Byron (1788-1824) and began to contradict myself. Here (from Byron's Complete Poetical Works) is "Thoughts Suggested by a College Examination." As is common today in literature and verse, the mathematicians (and scientists) are found wanting (though we are not the only deficient ones).

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

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.
