Songs of mathematics . . .

     Larry Lesser is a songwriter who uses lyrics for teaching as well as entertainment.  A varied sample of his creations for doing this are presented in his article "Mathematical lyrics;  noteworthy endeavours in education" found in the "Poetry and Mathematics / Special Issue" of the Journal of Mathematics and the Arts, March-June 2014).
     One of the article's enchanting items is a song for children -- "Circle Song" -- which Lesser has written to the familiar tune of "Twinkle, Twinkle, Little Star"; this lyric offers a way to remember critical formulas for a circle.

Circle Song     by Lawrence Mark Lesser

Take your finger 'round the jar:
Circumf'rence equals 2πr!

What is mathematics to animals?

In a playfully serious volume of verses by Eugene Ostashevsky we meet his alter ego, the "new philosopher" DJ Spinoza.  With the intelligence and bravery of the other philosopher-Spinoza (Baruch / Benedict, 1632 - 1677), Ostachevsky's Spinoza pokes a bit of fun at things that might be taken too seriously -- such as logic or mathematics or . . .

Spanish favorites

One of my favorite DC-area poet-people is Yvette Neisser Moreno -- who, besides giving us her own work, is active in translation of  Spanish-language poetry into English, most recently (with Patricia Bejarano Fisher) a Spanish and English edition of Venezuelan poet Maria Teresa Ogliastri’s South Pole/Polo Sur  (Settlement House, 2011).  Although I have not found any mathematical poems by Moreno, I learned from an interview that the Chilean Nobelist Pablo Neruda (1904-1973) is her favorite poet and I therefore present here the geometrically vivid opening opening stanza of Part XI of Neruda's well-known long poem, The Heights of Macchu Pichu: A Bilingual Edition (The Noonday Press, 1966).

Emily Dickinson -- and circumference

     Great poets may be investigated from many points of view.  For Emily Dickinson (1830-1886), some have noticed that her work employs particular terms from mathematics.  Including a much-quoted line -- "My business is circumference" --  in a letter to Colonel Thomas Wentworth Higginson, Dickinson is said to have used the word "circumference" in six letters and seventeen poems.  For example, the word appears in both of the poems offered below:

     633     by Emily Dickinson

     When Bells stop ringing—Church—begins
     The Positive—of Bells—
     When Cogs—stop—that's Circumference—
     The Ultimate—of Wheels.

Remembering Pi-day, a day late

Yesterday (3-14) was Pi-day, but my recent thoughts have been focused on my math-teacher son Eric (who has acute pancreatitis) and his family -- and I forgot to post this poem on the proper day.  Thanks to Lana Hechtman Ayers for these opening lines of  "Circumference:  A love poem."

Black History Month -- celebrate Haynes and Hughes

Living on the border of Washington DC I am exposed to items of local history for our nation's capital.  One such item involves the "discovery" of Langston Hughes (1902-1967) by poet Vachel Lindsay (1879 - 1931) at the Marriott Wardman Park Hotel, a leading conference hotel in the city.   A second story is a mathematical one.  Martha Euphnemia Lofton Haynes (1890-1980), a fourth-generation Washingtonian, was the first black woman to earn a PhD in mathematics -- conferred in 1943 by Catholic University.

More of Pi in Poetry

Recording artist Kate Bush has written a song entitled “Pi” which includes some of π's digits in the lyrics. Likewise, Polish Nobelist (1996) Wislawa Szymborska also features its digits in her poem, “Pi,” which begins:

Rhymes help to remember the digits of Pi

Calculated at the website, WolframAlpha, here are the first fifty-nine digits of the irrational number π (ratio of a circle's circumference to its diameter):

     π = 3.1415926535897932384626433832795028841971693993751058209749...

Before computers became available  to calculate π to lots of decimal places in an instant, people who did scientific calculations could keep the number easily available by memorizing some of the digits.  The website fun-with-words offers several mnemonics for  π , the most common type being a word-length mnemonic in which the number of letters in each word corresponds to a digit. For example the sentence, "How I wish I could calculate pi," gives us the first seven digits.

From "Red Has No Reason" -- a poem about the nature of mathematics

My new poetry book, Red Has No Reason, is now available (from Plain View Press or amazon.com).  Several of the poems mention math--and one of them comments on the nature of mathematics.  Ideas for "A Taste of Mathematics" (below) came from a mathematics conference in San Antonio, TX (January 1993) where it was announced that the billionth digit in the decimal expansion of  π  is 9.  Recently an amazing  new calculation record of 5 trillion digits (claimed by Alexander J. Yee and Shigeru Kondo) has been announced.
