1:58 PM | Thanksgiving, 2015
Thinking toward Thanksgiving Day tomorrow, I am grateful for  -- in addition to my children and grandchildren who will gather -- all of the mathematic and poetic voices that help me see our world. Happy Thanksgiving wishes for all who read here!

10:12 PM | Quoting Isaac Newton . . . . a "found" poem
     I do not know what     I may appear to the world;     but to myself I seem to have been     only like a boy playing on the seashore,     and diverting myself now and then     finding a smoother pebble     or a prettier shell than ordinary,     whilst the great ocean of truth     lay all undiscovered before […]
10:40 AM | Never Ask a Mathematician for Directions
I spent my formative years in a very rural county. Roads didn’t have names, or at least they didn’t have road name signs. In college, my urban friends used to claim that if you asked someone in my hometown for directions, they’d say: Go about a half mile, and turn left at Old Man Johnson’s […]

7:16 PM | "Ο ονομαστής, ο παρονομαστής" κι άλλα όμορφα στα κλάσματα!
Οι μέρες στο Γυμνάσιο περνούν πολύ γρήγορα. Ο χρόνος, όσο συναναστρέφομαι τους μικρούς μαθητές, γίνεται υπερκινητικός και φασαριατζίδικος. Ένα μελίσσι που ορμά στη γύρη. Μια μάζα ήχου, χρώματος και λάμψης, που άλλοτε μου αφήνει μια γλυκιά γεύση στα χείλη κι άλλοτε ένα ηχηρό […]

5:14 PM | Axiom: A Mathematics of Poetry
Today in a Facebook posting by Susanne Pumpluen I learned of Discov-her, an online journal featuring stories about women in Science. * * *      The following poetry offering is by Richard Smyth who has written a parody of an introduction to the mathematics of logic (specifically Laws of Form by G Spencer Brown*, Julian Press, 1972).  Smyth founded Anabiosis Press which offers the poetry journal Albatross and which has now evolved into Anabiosis […]

1:18 PM | Don’t Drink the Flavor Aid
Okay, boys and girls. Time for a pop quiz. Question 1. What cyanide-laced drink did 913 members of the Peoples Temple consume on November 18, 1978, as part of the largest mass murder-suicide in modern history? If you said Kool-Aid, well, you’d be in good company. Most Americans think that that was the drink of […]

1:51 PM | Encouragement from fathers, a second view
     Despite the importance of fathers' encouragement (as noted in my post on 13 November), some women oppose their fathers' views.  Recently I have been enjoying Rachel Swabby's Headstrong: 52 Women Who Changed Science and the World  (Broadway Books, 2015) and yesterday my reading focused on her bios of Maria Agnesi (1718-1799) and Ada Lovelace (1815-1852) and the roles their fathers played in their lives.  Agnesi was a child prodigy who wished to be a nun […]

9:28 PM | Encouragement from fathers
     It was my observation as a professor in a mostly-male mathematics department that the men who joined me in supporting opportunities for women were fathers of daughters.  They had come to see the world from a new perspective -- and saw that it needed changing.  Somewhat along these lines was a recent Washington POST article that told of recent research findings about socially responsible behavior from CEO's with daughters.      With […]
12:17 PM | Prime Time at NCTM Minneapolis
This afternoon, I’ll be presenting “Experience the Math Practices with Games and Online Tools” at the NCTM Regional Conference in Minneapolis. So if you unwittingly find yourself in the Minneapolis Convention Center at 1:30 p.m. today, please stop by. But how cool is this? My session is #210, and today is Friday, November 13. Awesome, huh?

2:36 AM | Wait, Wait… I’ve Got a Math Question
“Not My Job” is a segment on the NPR game show Wait, Wait… Don’t Tell Me! During the segment, host Peter Sagal asks a celebrity three questions, on a topic about which they likely have no clue. For instance, Cindy Crawford was asked questions about scale models, not supermodels; Rob Lowe was asked questions about […]

4:29 PM | Limericks for Hedy Lamarr
     When seeking to draft a poem quickly, it is useful to have some sort of pattern to follow -- a pattern helping to dictate word choice.  This morning, upon discovering Google's online celebration of the 101st birthday of inventor and actress Hedy Lamarr, I have wanted to join the commemoration with a poem.  A verse pattern rather often used by hasty math writers is the limerick (see links below) -- and I have today constructed this pair of limericks to praise […]

   Φέτος στη Β' Γυμνασίου, διδάσκοντας τις εξισώσεις α' βαθμού είχα την ευκαιρία να παρουσιάσω στα παιδιά, και να συζητήσω διεξοδικά μαζί τους, το περιβόητο μοντέλο της ζυγαριάς! Πάντα έκανα αναφορά στη ζυγαριά, κατά τη διδασκαλία της πρωτοβάθμιας εξίσωσης  στην Α' Λυκείου, […]

Στο 32ο ετήσιο Συνέδριο της Ελληνικής Μαθηματικής Εταιρείας είχα την τιμή και τη χαρά να παρουσιάσω την εργασία μου με τίτλο: ΜΕ ΠΟΙΟ ΜΟΝΤΕΛΟ ΓΡΑΜΜΑΤΙΣΜΟΥ ΜΠΟΡΕΙ ΝΑ ΕΠΙΤΕΥΧΘΕΙ Ο ΜΑΘΗΜΑΤΙΚΟΣ ΓΡΑΜΜΑΤΙΣΜΟΣ; ΠΕΡΙΛΗΨΗ: Ο μαθηματικός γραμματισμός, όπως ορίζεται σήμερα, […]
1:08 PM | Artificial Intelligence in the Library . . .
     Libraries are wonderful places and library book sales are temptations impossible to resist -- and so, during a recent trip to Boston and exploration of the historic public library buildings on Boylston Street, I purchased a copy of Living Proof  (Florida International University Press, 1985) by Edmund Skellings (1932-2012).  Born in Boston and a poet laureate of Florida, Skellings was a pioneer in the application of computers to the arts and humanities.  […]

9:56 AM | The Life and Times (and Fractions) of Eliza Acton
You may know Eliza Acton as an English poet or Victorian cookbook author, but I prefer to think of her as the Queen of MP.6. CCSS.Math.Practice.MP6: Attend to precision. Her bestselling Modern Cookery for Private Families — which was first published in 1845, ran through 13 editions by 1853, remained in print until 1918, was reissued in 1968 and 1974, and […]

1:48 AM | Mathematics and Poetry ARE Similar
        A recent email request sent me looking for a one-page article / quiz I had published in the American Mathematical Monthly in 1992 -- a list of 17 statements (quotations) each with a word missing.   The missing words are either "mathematics" or "poetry" (or a related word).  My claim is that, without using the author's name as a clue, it is difficult to decide which of these arts is intended.  I offer here the first four of the statements and […]

     Australian teacher and  poet Erica Jolly is convinced that breaking down the barriers that make silos of sciences and humanities subjects will promote better education systems and improve job prospects for students.  She brings mathematics into this engaging poem found in Holding Patterns, an online book of physics and engineering poems, part of the "Science Made Marvelous" project.Sculpture at Questacon (Australia National Science and Technology […]

7:04 PM | ΣΕ ΦΑΣΗ ΜΕΤΑΒΑΣΗΣ από το Λύκειο στο Γυμνάσιο
  Την τρέχουσα σχολική χρονιά, αποσπασμένη σε Γυμνάσιο ούσα, διδάσκω και στις τρεις τάξεις τα γυμνασιακά μαθηματικά για πρώτη φορά. Στο μακρινό παρελθόν, πριν ακόμη διοριστώ, είχε τύχει ενίοτε να ασχοληθώ με κάποια τάξη του Γυμνασίου, αλλά ποτέ με όλες μαζί ταυτόχρονα και […]

9:46 PM | Shepard Tones
I had the idea for this one while I was filming a microwave video. Outside, the San Francisco fog was rising and disappearing off of the hills, then re-condensing as clouds above. It was mesmerizing. The ever-rising effect of this fading in-and-out reminded me of Shepard tones, and I thought, I should film this and […]

4:03 PM | Celebrating waves of light . . .
     On October 8, Scotland's celebration of National Poetry Day had the theme "Light."  An online collection of themed poems suitable for children is available here.  From my Romanian friend, Doru Radu, who attended that celebration, I received poem-cards from the event. One of the cards contained a poem by filmmaker and poet Margaret Tait (1918-1999). I include that poem with its accompanying image below.   Did you say it's made of […]
10:51 AM | Fractional Eggs
I search for new recipes at allrecipes.com all the time. This morning, a search yielded a delicious recipe for pumpkin pancakes, which sounded like the perfect breakfast for a crisp fall morning. One of the things I love about allrecipes is the ability to customize the number of servings. The default number of servings for […]

9:31 PM | Use a phone App to find mathy poems
A day late, Happy Birthday, E. E. Cummings (b 14 October 1894, d 3 September 1962).     One of my favorite poetry sites is PoetryFoundation.org -- publisher of POETRY Magazine and supplier of a wonderful phone app (also entitled POETRY).  The app offers access to an enormous data-base of poems, sorted into categories that may be accessed using a SPIN feature, activated by touch.  Spinning the upper layer of categories can lead to "Humor" or "Joy" or […]

4:45 PM | Daughter and Father - a warm geometry . . .
     Kate Stange is a mathematician -- from the Canadian province of Ontario and now at the University of Colorado -- whose father, Ken Stange, is a visual artist and poet. I met them on the internet via our combined interests in the intersections of poetry and mathematics. Lots of years ago, Kate gathered an online anthology of mathy poems. One of her recent online ventures is the development of WIN -- Women in Number Theory.  Below I offer one of Ken Stange's […]
3:49 PM | Toward Infinity . . .
     During summer teaching opportunities a dozen or more years ago in Deva, Romania I met Doru Radu who taught English there -- and our mutual love of poetry led us to collaborate on English translations of work by Romanian poets George Bacovia and Ileana Malancioiu.  Now Doru is in Poland and he is translating Polish poetry into Romanian.  One of his favorite poets is Ewa Lipska -- a poet I have met via Poetry International.  Below is her poem "Newton's […]

9:07 AM | as i think i am
How I made this video: first I wrote the script then I figured out the shots I wanted and wrote those down too. Then I collected plastic teabag wrappers for a year and old earplugs and an honest grit of polenta. I looked at it sometimes, in that year. The script. At 10:48pm on Tuesday September […]

Were a state assessment item writer to get his hands on the puzzle that I discuss below, I believe that this is what the problem might look like: Fifteen congruent segments labeled A-O are arranged horizontally and vertically to form five squares, with five of the segments shared by two squares each.
