My maternal grandfather, James Edgar Black (1871-1931) was a western Pennsylvanian, a carpenter, and a man I never knew. But Ed, one of my cousins, found among our grandfather's long-stored things a scrapbook of collected poems and other miscellany that he recently passed on to me.

### Phenomenal Woman

Yesterday morning Maya Angelou (1928-2014) left us. But she has not left us alone. Her voice is with us, cheering us to be more than we were, to be all that we can become. Places to read her words and words about her include PoetryFoundation.org (scroll down past the bio for links to poems), Poets.org,

Angelou's poetry is filled with the geometry and motion of womanhood. For example:

### How many grains of sand?

Recently one of my friends used "all the grains of sand" as an example of an infinite set "because it is impossible to count them all" and -- even as I rejected his answer -- I wondered how many of my other friends might agree with it. In the following poem, mathematician Pedro Poitevin considers a similar question as he reflects on the countability of the birds in the night sky.

A synchrony of wings across the sky

is quavering its feathered beats of flight.

Their number is too high to count -- I try

### Math rap

Harry Baker is a Slam Champion who studies Maths at Bristol University, UK -- and his poetry sometimes features math, often having fun with the topic. His web page has a link to a rap about maths and at the JMM reading in Boston in 2012, Baker submitted this rap, 59 (a love story, now on YouTube), for presentation that evening.

### Public Image of a Mathematician

From John Dawson -- a professor emeritus of mathematics at the Penn State York campus and well-known for his publications in mathematical logic, often focusing on the life and work of Kurt Godel -- a poem on a topic that this blog visits from time to time, portraits of mathematicians.

Please,

I'm not an accountant.

No,

Mine doesn't always balance either.

What do I

Well,

On good days

I prove theorems;

### Pound on poetry and mathematics

HERE at PoetryFoundation.org we find an article by Carl Sandburg (1878-1967), published in

The complete article is available here.

And, in a footnote* to the poem "In a Station of the Metro" -- found in my

*POETRY**Magazine*in 1916, in which Sandburg offers highest praise to poet Ezra Pound (1885-1972). Sandburg includes this quote from a 1910 essay by Pound that connects poetry and mathematics.
"Poetry is a sort of inspired mathematics, which gives us equations,

not for abstract figures, triangles, spheres and the like, but equations

for the human emotions. If one have a mind which inclines to magic

rather than science, one will prefer to speak of these equations

as spells or incantations; it sounds more arcane, mysterious, recondite."

The complete article is available here.

And, in a footnote* to the poem "In a Station of the Metro" -- found in my

*Norton Anthology of Modern Poetry*we find a bit more of Pound's mathematical thinking.

### Land without a square

Here is a bit of light verse from the pen of John Updike (1932-2009).

**ZULUS LIVE IN LAND**

**WITHOUT A SQUARE**by John Updike

*A Zulu lives in a round world. If he does not leave his reserve.*

*he can live his whole life through and never see a straight line.*

--headline and text from

*The New York Times*

In Zululand the huts are round,

The windows oval, and the rooves

Thatched parabolically. The ground

Is tilled in curvilinear grooves.

### Barbie (b 1959) said (c 1990) "math is hard"

On April 24 I had the pleasure of reading at the Nora School with Martin Dickinson and Michele Wolf. Back in March I had posted Dickinson's "Homage to Euclid" but mathematics is not a a focus of Wolf's work. However, her poem below about Barbie has numbers, and any mention of Barbie reminds me of the controversy over "

by Michele Wolf

My worth is most inflated when, on tiptoes, I pose

In my original box, never handled, especially if I date

Back to '59 or '60. But that is rare. I am more used

To breaking out, to being the damp flamingo

Pecking to leave the shell. I prefer moving forward.

I was an astronaut in '65, a surgeon in '73. Last year

**math is hard**" -- one of the speeches uttered by an early 90's version of this doll. (Please visit this posting from June 14, 2010 -- on "Girls and Mathematics" for additional Barbie-comments and more Barbie poetry.)

### May 6, 1954

I learned about it via a news broadcast on Pittsburgh radio station KDKA and, for some reason, the event stuck firmly in my memory. I was 13 years old and on May 6, 1954 Roger Bannister ran a mile in less than 4 minutes. The integer 4 is a perfect square as was Bannister's age then -- 25. Alternatively, 13 is prime. As is 60 + 13 = 73. Yesterday marked 60 years since Bannister broke the record. I have come to love running. And playing with numbers.

I . . . never

will run out

of numbers.

### A pure mathematician (not!)

Poet Arthur Guiterman (1871-1943) was known for his humorous verse. Here is "A Pure Mathematician" -- a poem that stereotypes mathematicians in familiar, unflattering ways (from

Let Poets chant of Clouds and Things

In lonely attics!

A Nobler Lot is his, who clings

To Mathematics.

Sublime he sits, no Worldly Strife

His Bosom vexes,

Reducing all the Doubts of Life

To Y's and X's.

*The Laughing Muse*(Harper Brothers, 1915)). In contrast to Guiterman's verse that pokes fun at mathematicians, I invite you to visit this posting from 28 January 2011 to read Sherman Stein's "Mathematician" -- a poem that not only is more fair to the profession but also features a female mathematician.**A Pure Mathematician**by Arthur GuitermanLet Poets chant of Clouds and Things
