The Doomsday Rule

     My recently posted mention of Tristian Bangert's poem about John Horton Conway (1937-2020) sent me looking through my files for materials related to Conway's visit to Pennsylvania's Bloomsburg University in 1993.  During that visit, Conway entertained students with his explanation of the Doomsday Rule -- for calculating the day-of-the-week that corresponds to a particular date -- and I tried to capture his message (a lengthy one) in the following stanzas:

On What Day of the Week Were You Born?   

by JoAnne Growney

These lines were inspired by John H. Conway's presentation, "Calendar Calisthenics and Calculations," at Bloomsburg University on January 26, 1993.

A man that I met
named Conway, said "Why?"
should the hard be hard
when the hard can be easy
with just a bit of effort.    

Admiring John Conway with stories of numbers

     Recently I was contacted by Thomas Barr, Director of Programs at the American Mathematical Society who told me of poetry written by a student from Flagstaff, AZ; Tristian Bangert of Coconino Community College has written about the discovery by John Horton Conway (1937-2020) of the surreal numbers -- and I offer part of his poem below; contact information for the poet is offered at the end of this post:

from Conway     by Tristian Bangert

     There once was a man

     Who knew naught but numbers

     Joined by their presence

     The numbers, wondering

     "Where has your kind been? 

     Have you not wondered who was here before you?"  

Hailstone numbers shape a poem

     One of my favorite mathy poets is Halifax mathematician Robert Dawson -- his work is complex and inventive, and fun to puzzle over.  Dawson's webpage at St Mary's University lists his mathematical activity; his poetry and fiction are available in several issues of the Journal of Humanistic Mathematics and in several postings for this blog (15 April 2012,  30 November 2013, 2 March 2014) and in various other locations findable by Google.
      Can a poem be written by following a formula?  Despite the tendency of most of us to say NO to this question we also may admit to the fact that a formula applied to words can lead to arrangements and thoughts not possible for us who write from our own learning and experiences.  How else to be REALLY NEW but to try a new method? Set a chimpanzee at a typewriter or apply a mathematical formula.
     Below we offer Dawson's "Hailstone" and follow it with his explanation of how mathematics shaped the poem from its origin as a "found passage" from the beginning of Dickens' Great Expectations.
