Happy Pi-Day

 

Celebrate PI AND Remember its digits

     Friday, March 14 (3.14) will be π-day -- and I look back and remember how one of my high school math teachers challenged me and my classmates to come to class prepared to recite as many digits of π as we could remember,  I was not a particularly good memorizer and was delighted  to learn that the lengths of the words in this sentence:

How I wish I could calculate pi !

are the first seven digits of pi . . . . and the lengths of the words in the following rhyme give the first thirteen digits:

                      See, I have a rhyme assisting
                      my feeble brain,
                      its tasks sometime resisting.

Celebrate Pi-Day

 3 . 1 4 1 5 9 2 6 5 3  .  .  . 

March 14  -- that is, Pi-Day -- will soon be here.  One of the ways of celebrating  π  is with dessert pastries (pies)  -- but a  π-day  greeting often takes on the challenge of a message in Pilish -- a language whose word-lengths follow the digits of  π -- a challenge that students often enjoy!   An example:

Hug a tree, I shout -- hungering to defend trees and  . . .

Observe Pi-Day by writing in Pilish

      Many poets use constraints to shape their writing but few are as constrained as mathematician Mike Keith who has written many works in Pilish -- that is, a language in which the flow of words have lengths that follow the digits of Pi.  In honor of 2020's Pi-Day on 3.14, I have developed a small bit of Pilish, a poem of sorts, which I offer below.

 

 Entering the term "Pilish" into this blog's SEARCH box finds these earlier postings that celebrate Pi. 

 The first 50 decimal digits are 3.14159265358979323846264338327950288419716939937510 . . .

Again we celebrate Pi !

 Now I give  -- I again enumerate π's digits, count out . . .

Tuesday, March 14, is Pi-day -- and I invite you to browse or SEARCH this blog for references to π / Pi and to learn more about Pilish (a language in which, as above, word-lengths follow the pattern of the digits of π).  Here are a links to several of the postings available:

       Rhymes to help you remember the digits of Pi
       Poetry that imagines auctioning the digits of Pi
       A Circle poem in Pilish 

Inspired by Pi

     Last year, a few days after Pi-Day, my email had a link (Thanks, Paul Geiger!) to an example of Pilish -- this one a circle poem by Mike Keith that represents the initial 402 digits of Pi  -- and I have, at last, posted the poem below.  Keith's poem first appeared in the The Mathematical Intelligencer in 1986. 

     And here is a link to musical Pi --at the webpage of "The Derivatives" are math parodies written and performed by Bloomsburg University professors William Calhoun, Kevin Ferland, and Erik Wynters, including The Pi  Song (also known as 3.14159/Circle).
