Can you multiply with Roman numerals?

     Canadian writer Siobhan Roberts (whom I know from BIRS workshops) has a recent New Yorker article that celebrates the 100th birthday and achievements of Claude Shannon (1916 -2001) -- often referred to as "the father of the information age." Most of the important information in that article I leave for you to read for yourself, but I call to your attention to one of Shannon's accomplishments featured therein -- Claude Shannon built a machine for doing arithmetic with Roman numerals.  This connects to poetry via a poem by Ron Padgett, below.
The Roman numeral system has largely been abandoned 
because arithmetic is less cumbersome with a place-value system.
 Here is a link to a site that exhibits procedures for Roman numeral arithmetic.

 The Roman Numerals     by Ron Padgett

       It must have been hard
       for the Romans to multiply
       —I don’t mean reproduce,
       but to do that computation.

"The Computation"

     Here is a favorite poem of mine -- and it available with many others in the anthology, Strange Attractors:  Poems of Love and Mathematics (A K Peters, 2008), edited by Sarah Glaz and me.

     The Computation     by John Donne (1572-1631)

     For the first twenty years, since yesterday,
     I scarce believed thou couldst be gone away,
     For forty more, I fed on favours past,
         And forty on hopes, that thou wouldst, they might last.
     Tears drowned one hundred, and sighs blew out two,
         A thousand, I did neither think, nor do,
         Or not divide, all being one thought of you;
         Or in a thousand more, forgot that too.
     Yet call not this long life; but think that I
     Am, by being dead, immortal; can ghosts die?

How clever of Donne, writing all those years ago, to speak (indirectly, at least) to 2016's Math Awareness Month theme, "The Future of Prediction."

Nature poems -- at Stillwater

     As noted in my 5 August posting, the Stillwater poetry festival (organized by Kevin Clark) was scheduled for last Saturday, September 7 -- and I was (though delayed by the death of a car battery) able to attend.  A time to catch up with old friends -- River Poets Dave Barsky, Carol Ann Heckman, and Janet Locke, and Wilkes-Barre poet Richard AstonPoets 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.

Pipher -- Math experiments, Pi


     'Tis a favorite project of mine
     A new value of pi to assign.
          I would fix it at 3
          For it's simpler, you see,
     Than 3 point 1  4  1  5  9.

How much for a digit of PI?

Scottish poet Brian McCabe writes playfully of numbers.  In the following poem he imagines an auction of the digits of π.

   Three Point One Four One Five Nine Two
   Six Five Three Five Eight Nine Seven Nine
   Three  Two Three Eight Four Six Two Six
       Four Three Three Eight Three Two
         Seven Nine Five Zero Two Eight             by Brian McCabe

Thinking about Thinking

The question of what it means to think is never far from my focus -- and is particularly on my mind during these days that the computer Watson is competing on the TV game show, Jeopardy.   Here is a poem I like a lot -- "New Math" by Cole Swensen  -- in which the poet (writing more than 20 years ago) considers the limits of computation (and whether it could aid persons unable to recognize faces).

Rather like an elephant

What is mathematics?
          These days I am outside of mathematics looking in and my views of the subject are more complex than during the days when I was a professor and mathematician. Back in my math-prof days -- when I moaned about those who held the view that mathematics is merely computation -- I tried to explain to uncompreheding friends the role of calculation within mathematics with this analogy:  computation is to mathematics as spelling is to poetry.  But those for whom computation is all of their mathematics do not accept this argument.  Indeed, I myself now have the notion that one can navigate life competently without algebra -- much as I get along without Spanish or Chinese. But I regret not knowing them -- they are, like algebra, among the world's important languages.

Mathematics, like poetry, is ART

Doing mathematics is often misunderstood as primarily computation--an error that seems equivalent to seeing poetry writing as primarily a spelling exercise.
