Math in Shakespeare . . .

     Yesterday, April 23, is the day on which William Shakespeare's birthday is celebrated; he was born long ago in 1564 and the actual date is uncertain.   The BBC Radio Newshour today featured this event in its broadcast  and told of ways that Shakespeare used mathematical ideas in his writing.  A broadcast recording is available at this link; the Shakespeare-math info begins at approximately 25 minutes into the show.   Ideas come from a book that is coming out next September,  Much Ado About Numbers: Shakespeare's Mathematical Life and Times by Rob Eastaway. 

One of the interesting items I found as I browsed was the phrase

    eight score eight       in Othello -- a three-syllable way for saying 168.

     Here is a link to an article that focuses on Shakespeare's use of zero.

Inventing Zero

     A Pennsylvania friend who is now in Oklahoma, Sharon Solloway -- whom I got to know when we were both faculty members at Bloomsburg University (now part of Commonwealth University)  --  shared with me on Facebook the following mathy poem,  "Inventing Zero" by Canadian astronomer Rebecca Elson (1960-1999).  Found in Elson's collection,  A  Responsibility to Awe (Carcanet Classics, 2018)  "Inventing Zero" is available along with other samples of Elson's work here at this link.

       Inventing Zero      by Rebecca Elson

               First it was lines in the sand,
               The tangents, intersections,
               Things that never met,
               And you with your big stick,
               Calling it geometry,   

Number Personalities . . .

      Sometimes our experiences with objects or ideas leads us to assign them personalities -- a notion illustrated in the poem "Zero," by Sue Owen, a poem that lives on my shelf in the anthology Verse and Universe:  Poems about Science and Mathematics, edited by Kurt Brown (Milkweed Editions, 1998), and offered below.

Zero     by Sue Owen

       This is the story of zero,
       born to live a life
       of emptiness, only
       child of plus and minus.

       Its bones invisible
       so it could be seen through
       like an eye.
       With that vision, you could      

Division by Zero

     At Victoria University in Melbourne, novelist, playwright and poet Tom Petsinis also teaches mathematics.  He participated in the 2016 Bridges Math-Arts Conference in Finland this summer:  here are two of his poems from the 2016 Bridges Poetry Anthology -- and each of them plays with mathematical ideas in new and thoughtful (sometimes amusing) ways.   "Zeno's Paradox" follows this initial poem.  (Names and links for other anthology poets are given below.)

     Division by Zero     by Tom Petsinis

     She could’ve been our grandmother
     Warning us of poisonous mushrooms ‒
     To stress her point she'd scratch
     The taboo bold with crimson chalk.
     It should never be used to divide,
     Or we'd be howled from lined yard
     To pit where cruel paradoxes ruled.
     Her warnings tempted us even more:
     Young, growing full in confidence,
     We’d prove the impossible for fun ‒
     Nothing she said could restrain us
     From showing two is equal to one.   

Uncertainty . . .

     Sometimes we find things of great value when we are looking for something else -- in fact, Argentinian writer Jorge Luis Borges has said, The best way to find a good thing is to go looking for something else . . .
     One of my recent stumbles (while looking for work by Borges) was onto the website of Robert Ronnow -- and I have found it a fun place to browse.  Here is a sample, a poem from his recent collection, The Scientific Way to Do Mathematics:

Uncertainty       by Robert Ronnow

                                                       --with a line by Pico Iyer

There cannot be two identical things in the world. Two
hydrogen atoms
offer infinite locations within their shells for electrons.
Thus, nothing can be definitely eventually known. 

Three Greguerías

From Portugal, from Francisco -- who emailed me the gift of these lines:

Three Greguerías   by Rámon Gómez de la Serna (1888-1963)
                                             translated by Francisco J Craveiro de Carvalho and JoAnne

Holding her hoop the little girl goes to school and to the playground,
to play with the circle and its tangent.

Zeros are the eggs from which all the other numbers are hatched.

Numbers are the best acrobats in the world: they stand on top of each other without falling down.

Ramón Gómez de la Serna is considered the father of the greguería -- a one-liner in which he combined gentle humor with a metaphor. 

The Role of Zero

     In mathematics, as in poetry, multiple meanings are common and create power for the language.   For example, the number 0 is an idempotent element, an additive identity, a multiplicative annihilator -- and it also plays the role of something that may represent nothing.
     In Dorothea Tanning's poem below -- I found it at poets.org -- zero takes on still another of its roles, that of place-holder -- as in the numbers 101 and 5000, for example.

       Zero     by Dorothea Tanning (1910-2012)

       Now that legal tender has
                    lost its tenderness,
       and its very legality
               is so often in question.
       it may be time to consider
       the zero--
                    long rows of them.
            empty, black circles in clumps
                              of three, 

The gift of a poem

     In this holiday season of giving, sometimes the gifts are poems -- and sometimes mathy poems.  A few days ago, "Zero" by Robert Creeley (1926-2005) arrived in an email from Francisco José Craveiro de Carvalho, a Portuguese mathematician who loves poetry and has translated many math-related poems into his native language -- a seeker and finder of such poems who shares them with me.  (See also 23 October 2010 and 17 September 2013.)  At this time of giving and receiving, enjoy playing with these thoughts of zero as nothing or something.

          Zero     by Robert Creeley

                              for Mark Peters

          Not just nothing,
          Not there's no answer,
          Not it's nowhere or
          Nothing to show for it -- 

Taken out of context . . .

Sometimes good lines fit so well into their poems that their individual merits go unrecognized.  And then, taken out of context, they can lead lives of their own.  Here is a start for a collection of such lines.

From Poets.org here are two lines from "Ceriserie" by Joshua Clover:   

       Mathematics: Everyone rolling dice and flinging Fibonacci, going to the opera, counting everything.

       Fire: The number between four and five.

Love Physics

It turns out that one of the disadvantages of a long-term blog with lots of worthy material is that sometimes I lose track of fine work that I want to post.  And sometimes I find it again.  This morning I came across this poem by California conservationist Richard Retecki.

     Love Physics     by Richard Retecki

     equal forces
     oppositely directed
     canceled to zero

     then we tricked you
     exchanging pressure for light 

Found: Elementary Calculus

Here is a poem by Saskatchewan poet Karen Solie.

       Found     by Karen Solie

       Elementary Calculus

                From    Elementary Calculus  A. Keith and W. J. Donaldson.
                          Glasgow:  Gibson, 1960.

       Speed (like distance)
       is a magnitude and has no
       direction; velocity (like displacement)

       has magnitude and direction.  

Making something of nothing

     Was zero invented or discovered?  When and how?  By whom?  In "The Origin of Zero" -- an article published in 2009 in in Scientific American --  John Matson introduces an interesting history of zero (something vs. nothing and so on...).  Recently through the Splendid Wake poetry project (with an open-to-all meeting on Friday March 21 -- go here for details) I have connected with Washington DC poet William Rivera who has shared with me this poem that also examines the puzzle of the somethingness of nothing.

Nothing Changes Everything     by William Rivera

Number personalities

In his collection, Zero, Scottish poet Brian McCabe raises questions about numerical classifications.  He begins "The Fifth Season" with "Everyone talks of the four / -- none speak of the fifth." Another poem, "The Seventh Sense, " moves from a similar beginning " . . . none speak of the seventh" into a dreamy apprehension of the magical possibilities of items not yet classified. The following selection from Zero, "Triskaidekaphobia," offers remedies for the fear of bad luck brought by 13. 

Zero Power

To neutralize the differing effects of any non-zero numbers -- to wipe out vast differences between numbers -- we may raise each of them to the power zero.*  When 0 is applied as the exponent for any nonzero number, the result is 1.  So 7⁰ = 1 and 5378 ⁰ = 1 and (.001)⁰ = 1.   And here are "zero power" and other mathematical concepts interpreted in a poem.

     N to the Zero Power     by Laurie Clemens

     He holds one photograph
     featuring one man and one woman.

     Three birds perch on two wires
     forming an isosceles triangle over the last
     red brick street in town.

Latitude, longitude, and inauguration

Elizabeth Bodien now lives in a rural area in eastern Pennsylvania -- settling there after other lives in California, in Japan, in West Africa.  Here is a narrative poem using the geographic numbers of latitude and longitude drawn from the years that she was a childbirth instructor in West Africa.

Zero-Zero     by Elizabeth Bodien

Sophie Germain dressed as a man to study math

One of the fine sources for biographies and other topics in the history of mathematics is MacTutor History of Mathematics archive, hosted by the University of St Andrews in Scotland.  Poet Brian McCabe cites this archive for historical information he used as background for his poems starring mathematicians -- found in his collection, Zero (Polygon, 2009).  Here is McCabe's poem for the outstanding French mathematician, Sophie Germain (1776-1831). 

Computer code -- is poetry?

Dubliner Eavan Boland is a master poet (and one of my favorites); Ireland shares her with the creative writing program at Stanford University.  In Against Love Poetry (Norton, 2001), we find Boland's tribute to the also-amazing master of language, Grace Murray Hopper (1906-1988).

                     Code          by Eavan Boland

             An Ode to Grace Murray Hopper  1906-88

    maker of a computer compiler and verifier of COBOL 

   Poet to poet.  I imagine you

     at the edge of language, at the start of summer

       in Wolfeboro, New Hampshire, writing code.

         You have no sense of time.  No sense of minutes even.

           They cannot reach inside your world,

             your gray work station

               with when yet now never and once.

                 You have missed the other seven.

                   This is the eight day of Creation.

Valley Voices

With Richard Aston I share a love for science and logic, a love for poetry, and a love for the Susquehanna Valley.  His home is Wilkes-Barre and mine was (for 25 years) Bloomsburg -- both Northeastern Pennsylvania Susquehanna River towns.  We met long ago at a gathering of the Mulberry Poets (a group in which Richard remains active) in Scranton.  His recent collection of poetry Valley Voices (Foothills Publishing, 2012) has recently arrived in my mailbox and I'd like to share one of the voices in his collection -- a gathering of poems from a writer who has listened to the members of the communities in which he lives and has created memory portraits so that they will not be forgotten.  Here is one of his Susquehanna valley voices. 

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 

Division by zero

The November 2011 issue of the Scottish ezine, The Bottle Imp, is just out and it includes my review of poet Brian McCabe's Zero (Polygon, 2009). To stir your interest, I include a few lines from McCabe's title poem (which chronicles the irregular history of zero) -- and then offer a human interpretation of division by zero in a poem by Ann McNeal.
