Special Days for Mathematics

Today is the birthday of black mathematician, astronomer, almanac-writer and puzzle-maker Benjamin Banneker (1731-1806) -- and some of his puzzles were poems:  this link leads to this blog's previous postings of his work.

This week (November 9-14) is  2020 Maths Week in England.  Learn more, via an introductory video, here.

During these Covid-19 days of isolation I am particularly aware of distances that separate me from those I love . ..  and the numbers that keep track of it all.  Here are opening lines from the poem "Distances" by Peter Meinke that reflect on the changeable meanings of numbers. 

Welcome DIVERSITY in mathematics

     As February on the calendar brings BLACK HISTORY month and March brings WOMEN'S HISTORY month, I invite you to explore the contributions of diverse groups to mathematics.  In this blog, I celebrate links between a rainbow of math-people and poetry -- for example, in this posting, "Mathematicians are not just white dudes, (which includes links to math-poetry by Benjamin Banneker and Scott Williams). 

Remember -- and Celebrate

     Today as we remember Martin Luther King, I invite you to visit postings in this blog that celebrate his life -- follow this link.  

And here is a link to

a poem by black mathematician, Benjamin Banneker.  

And one more link -- 

          this one to The Mathematician's Project 

("Mathematicians Are Not Just White Dudes.")

Mathematicians are not just white dudes . . .

     Recently I found the wonderfully informative website arbitrarily close: musings on math and teaching -- my first visit to the site was to this 2016 posting about "The Mathematician's Project" -- a project and posting that offers lots of resources and links to introduce us to female mathematicians, black mathematicians, and more . . . 
     The following lines are from a puzzle-poem by mathematician-poet Benjamin Banneker -- a non-white dude; the sample has been obtained from a website that celebrates Banneker -- a website compiled by Washington, DC high school teacher John Mahoney.  These lines come from Puzzle 5:

Math-poetry for Black History Month

     Recently I have revisited my post (from October 2, 2012) that offers a puzzle poem by math-science guy Benjamin Banneker (1731-1806), "The Puzzle of the Hound and the Hare" and available here.   
     This link leads to several more posts that also offer mathy poems linked to African-American history and culture.  And here, below, is a treasure to enjoy in any month:

     Addition     by Langston Hughes (1902-1967)

     7 x 7 + love =
     An amount
     Infinitely above:
     7 x 7 − love.

Hughes' poem "Addition" is found in the anthology Strange Attractors: Poems of Love and Mathematics (AK Peters/CRC Press, 2008), edited by Sarah Glaz and me and first posted in this blog, along with other poems celebrating to Black History Month, on February 20, 2011.

Excitement of Proving a Theorem

Wow!  From first sighting, I have loved this description:

       I prove a theorem and the house expands:
       the windows jerk free to hover near the ceiling,
       the ceiling floats away with a sigh.

These lines from "Geometry" by Rita Dove express -- as well as any string of twenty-four words I can think of -- the excitement experienced from proving a theorem.

Puzzle poems from Benjamin Banneker

Benjamin Banneker (1731 - 1806) was a free African American mathematician and almanac author -- also an astronomer, surveyor, and farmer. (I learned of his work through my friend Greg Coxson, an engineer, teacher, and fan of mathematical poetry -- and Coxson learned of Banneker through a school project of his son.)  Beyond building a wooden clock and helping to lay out the borders of Washington, DC, Banneker predicted the 1789 solar eclipse and included rhyming math puzzles in his almanac.  Coxson introduced me to a fine website, established by by John F. Mahoney of Washington, DC's Benjamin Banneker Academic High School, entitled The Mathematical Puzzles of Benjamin Banneker.
     Banneker's Almanack had an eclectic mix of astronomy/astrology, medical advice, weather prediction, and other things.  Here's a math-problem-poem from that Almanack -- found, along with others, at Mahoney's site:
