11:09 AM | Counting Years -- in p'Bitek's Song of Lawino
Okot p'Bitek (1931-1982) was a Ugandan poet; one of his central concerns was that African literature should be built on African rather than European foundations.  His epic poem Song of Lawino (East African Publishing House, 1966) is a narrative poem written in the voice of Lawino who appeals to her husband Ocol to stay true to his own customs, and to abandon his desire to be white.  Here is a section of that poem that addresses a system for counting years.from   Song of […]

Το κείμενο που αναρτώ είναι της συναδέφλου Δέσποινας Ν., που είναι φιλόλογος και τεκμηριώνει με τον δικό της ιστορικό τρόπο την επιλογή της στο "ΟΧΙ".  Το αναρτώ για τρεις κυρίως λόγους:  1ο. Ως απάντηση σε εκείνους τους μαθηματικούς που θεωρούν ότι η μαθηματική λογική […]

2:37 PM | A Voice Meant to be Spoken
     Last month the Library of Congress named a new poet laureate, Juan Felipe Herrera, a Californian and Mexican-American whose work often involves oral performance  - as in “187 Reasons Mexicanos Can’t Cross the Border,” (City Lights, 2007).  As I have learned about this poet I have found that I identify with his process,  "I write while I’m walking, on little scraps of paper,” he said.  (Wasn't walking also a writing strategy for William […]

Welcome to Season 3 of Geometry Daily! I will continue what I did in 2012 (Season 1) and 2013 (Season 2): Creating a new minimal geometric composition each day.Oh wow, that was some time ago since the last post. I did a lot of collaborations, prints, shirts, etc. Also, I settled in my new job at the university and had some serious family time. Now it’s time to do what I love and it’s more fun than ever!The rules do not change: square format, one clear idea, simulated print of no more than […]

9:25 PM | Sex, Maths, and the Brain
I found this poetry in an abstract (with a link posted at "Women in Maths" on Facebook) for a lecture by Professor Gina Rippon entitled "Sex, Maths, and the Brain" at Aston University in Birmingham, England, on 30 June 2015.  Enjoy!Is there such a thing as a maths brain? Are mathematicians born or made?  Is the lack of girls in maths subjects a 'brain' problem? . . . the under-representation of women in mathematics is not a "biological […]

8:15 AM | 360 Video for Tau Day
I made a Tau Day video with a full Tau radians. I don’t usually make Tau Day videos (just the one), but in the past few days people have been asking, and so I found myself thinking: if I were to make a Tau Day video, what would it be? Here I’ve been busy working with […]

11:15 AM | The power of eleven
One of my recent poetry acquisition treasures is Measure for Measure:  An Anthology of Poetic Meters, edited by Annie Finch and Alexandra Oliver (Everyman's Lbrary, 2015).  From DC poet and friend, Paul Hopper, a few weeks ago I received comments about one of the sections of this collection  -- a section containing stanzas in hendecasyllabics, that is, in 11-syllable lines  Hopper has sent a sample quatrain of hendecasyllabics that points to "Into Melody" by Lewis […]

10:03 PM | Found poetry -- Mary Cartwright
Recently I have been reading about mathematician Mary Cartwright (1900-1998) and working to develop a poem about her -- relying on a fine article/interview by my friend Jim Tattersall published in the The College Mathematics Journal (September 2001).  Her work on the foundations of chaos theory was prominently presented in a 2013 BBC News article.   A couple of days ago my acquisition of Rachel Swaby's book -- Headstrong Women:  52 Women Who Changed Science and the World  […]

     Sometimes we find things of great value when we are looking for something else -- in fact, Argentinian writer Jorge Luis Borges has said, The best way to find a good thing is to go looking for something else . . .     One of my recent stumbles (while looking for work by Borges) was onto the website of Robert Ronnow -- and I have found it a fun place to browse.  Here is a sample, a poem from his recent collection, The Scientific Way to Do […]

Reading today's Washington Post, a surprising statistic:               Sharks don't kill               as   many               as cows do.  In the years 2001 to 2013 in the US an average of 20 deaths annually were caused by cows, compared with 1 during each of those […]

Baseball fans do lots of dumb things. Wear a foam finger. Act like they’re smart because they correctly chose the attendance from the four choices on the big board. Throw trash at the lower levels. Streak the field. Root for the Yankees. (And while we’re at it, the 1980’s called. They want “The Wave” back.) […]

12:49 PM | 5 People Born in the 1800’s — and Still Alive!
There’s been a big deal made this week about the five people still alive who were born in the 1800’s, and rightfully so. As I wash down an A1 Peppercorn Burger from Red Robin and a bag of Cheetos with a Dr Pepper, I’m not even sure I’ll make it to 50, let alone 115. I feel bad […]
12:40 PM | A portrait of TB in numbers
Poet Sarah Browning recently directed me to "Tuberculosis in Numbers," a fine poem by M.

Brett Gaffney         “In the past, we have been unable to get a true picture of the TB situation        in Louisville due to the method of keeping statistics.” – Dr. Oscar O.

Walk him, and pitch to the rhino. (If you’re wondering what my favorite joke is, read all about it in Make Your Own (Math) Joke.) […]

Poetry found in the words of Galileo Galilei (1564-1642): "Philosophy is written in this grand book, the universe, which stands continually open to our gaze.  But the book cannot be understood unless one first learns to comprehend the language and read the lettersin which it is composed.It is written in the language of mathematics, and its characters are triangles, circles, and othergeometric figures without which it is humanly impossible to understand a single word of it.”Galileo […]
