### Learning slowly . . savoring difficulty . . .

There are geniuses (like Srinivasa Ramanujan) who learn mathematics quickly -- but I am not one of them.  In the following poem I reflect on how I learn . . .

Reflection     by JoAnne Growney

I read and I did not understand.
Less than a page.
I read slowly and I did not understand.
My notes were three times as long as what I had read.

I rewrote what I read in my own words.
I reread it and inserted extra clarifying words.

### Poetically exploring the the invention of "i"

Today's posting features work by Punya Mishra, professor and administrator at Arizona State University -- a writer who offers explanations of mathematical concepts in his poems, explanations that can appeal to students!   Mishra's website features several mathy poems and in our email correspondence he said that "The Mathematical i" is his favorite.  Here are are several stanzas:

from  The Mathematical    by Punya Mishra

The negative numbers were full of dismay
We have no roots, they were heard to  say
What, they went on, would be the fruit
of trying to find our square root?

Matters seem to be getting out of hand
Since the negatives have taken a stand,
On the fact that positives have two roots, while they have none.
They plead, would it have killed anybody to give us just one?
The square roots of 4 are + and – 2! As for -4 ?  How unfair,
He has none! None at all. Do the math gods even care?

### Remembering Leonardo da Vinci

One of the readers featured at the recent 1/17/2020 JMM math-poetry reading was Italian mathematician/poet Rosanna Iembo.  Below, with Iembo's permission, I offer a sample from her poem, "A New Dawn"  -- a poetic narrative in the voice of Leonardo da Vinci, a genius of the Italian Renaissance.  Here are a few lines from this narrative; the entire work is available from the poet (contact information is offered here on her website.).

Referring to Luca Pacioli, the poet's voice of da Vinci says:

With him
a common feeling
that did not end over the years.

And in the "Proportion"
which he decided to call
"Divine"
where I drew
my polyhedra,
understanding
reached maximum splendor.

### Focus on FOUR

Numerous poems by Canadian poet Alice Major connect to science and mathematics, and Major has connected me with Ottawa poet and mechanical engineer Sneha Madhavan-Reese -- who has shared with me not only poetry but also the new-to-me fact that her home city of  Ottawa lies on the traditional and unceded territory of the Algonquin Nation.  Here is Madhavan-Reese's poem, "Four," a thoughtful reminder of the vast versatility of mathematical notions.

Is 4 the same 4 for everybody? -- Pablo Neruda, The Book of Questions

My mother draws her four with a right angle;
my father's is pointed on top.  My daughter's four,
half the time, is backwards.  Her sister signs,
tucking a thumb into her raised palm.

### The world of Math Girls . . .

This past weekend my oldest granddaughter turned sixteen -- and I intensely want every career door to be open to her and to my other granddaughters (and my grandson).  The times are changing, new doors are opening for girls and women,  Still, these syllable-square thoughts are on my mind this morning.

Math Girls

A math girl must be
smarter than the rest –-
yet must be modest
and never claiming.
Math-World is not fair.

And here are more of my mathy-perhaps-poetic thoughts.

When you’re a math girl you may be the only girl in the room.
A math girl must be three times as good to be equal.

### We become what we think . . .

Browsing a recent issue of World Literature Today, I have found a thought-provoking activist poem by Linda Hogan that considers the ways we are shaped by "our numbers."  I offer below its opening stanzas:

Embodied   by Linda Hogan

I am embodied first by the numbers
given my grandparents,
no choice but to sign the Dawes Act.

### With bits of mathematics, a poem for a New Year

Here -- containing bits of mathematical terminology --  is an excerpt from "A Poem for the New Year" by Nigerian poet Christopher Okigbo (1932-1967).

from    A Poem for the New Year     by Christopher Okigbo

Where then are the roots, where the solution
To life’s equation?

The roots are nowhere
There are no roots here
Probe if you may
From now until doomsday
We have to think of ourselves as forever
