*The Marvelous Arithmetics of Distance*.

**Smelling the Wind**by Audre Lorde

Rushing headlong

into new silence

your face

dips on my horizon

the name

of a cherished dream

Audre Lorde (1934-1992) is one of my favorite poets; links to my previous postings of her work in this blog are given below. Here is the opening poem from one of Lorde's collections, *The Marvelous Arithmetics of Distance*.

A Fractal Poem Dec 28, 2014

Recent discovery of gravitational waves has put Einstein (1878-1955) -- and even Newton (1643-1727) -- into recent news, and a visit to one of my favorite reference collections, James R. Newman's four-volume collection, *The World of Mathematics*, finds those two giants celebrated in verse:

Here are links to information about the poets named above: Lord Byron (1788-1824), Alexander Pope (1688-1744), and Sir John Collings Squire (1884-1958) -- and these links lead to previous blog postings that feature*The World of Mathematics*: March 22, 2011 and August 2, 2011.

Sometimes I try to write a poem that explains a mathematical concept -- it's a difficult task My effort usually results in something that sounds more like a textbook paragraph than a poem. And I was thereby hugely delighted (following a lead from Colm Mulcahy) to discover this poem by Grant Sanderson that has fun with a famous mathematical formula due to Euler:

**e**^{iπ}** + 1 = 0 **or, stated differently** ****e**^{iπ}** = -1 **

**Euler Formula** by Grant Sanderson

Famously

start with e,

raise to π

with an i,

we've been taught

by a lot

that you've got

minus one.

Most of Martin Gardner's fans are avid puzzler's -- my connection with him is also one of admiration (he was a thoughtful person who was a master at making connections among disparate things) but we are connected via poetry, including topics such as counting all possible rhyme schemes for a given stanza and the constraint-based poetry of *OULIPO* . . ..

Gardner (1914-2010) was not a poet -- although he penned a quatrain or two, his great contribution was collecting and publicizing parodies and puzzle-verses by others. Here is a link to Gardner's collection of poetic parodies, and here is a link to many of Gardner's puzzles, including the stanza below, "How Old is the Rose-Red City?"

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.)

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*.

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:

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.
