Focus on FOUR

     Numerous poems by Canadian poet Alice Major connect to science and mathematics, and Major has connected me with Ottawa poet and mechanical engineer Sneha Madhavan-Reese -- who has shared with me not only poetry but also the new-to-me fact that her home city of  Ottawa lies on the traditional and unceded territory of the Algonquin Nation.  Here is Madhavan-Reese's poem, "Four," a thoughtful reminder of the vast versatility of mathematical notions.

               Is 4 the same 4 for everybody? -- Pablo Neruda, The Book of Questions

       My mother draws her four with a right angle;

       my father's is pointed on top.  My daughter's four,

       half the time, is backwards.  Her sister signs,

       tucking a thumb into her raised palm.   

Rules that someone made up -- Is that MATH?

      As frequent readers of this blog know, I am indebted to many people for their contributions of poems -- their own and links to others.  An alert to today's poem came from Canadian poet Alice Major -- with previous contibutions to this blog found at this link.   The poem, "BOUNDARY CONDITIONS"  by Sneha Madhavan-Reese was published in the journal Rattle.   I offer, below, its opening and closing stanzas, followed by a link to the complete poem.

                    who but men blame the angels for the wild
                           exceptionalism of men?    —Sam Sax, “Anti-Zionist Abecedarian”

       Along the border of any governed region, there exists a value which must
       satisfy its laws. This is a rule I learned for solving differential equations.
