Antimatter What if everything was antimatter, EXCEPT Earth? Sean Gallagher This one doesn't end well for us. But—unlike most scenarios involving the word "antimatter"—the end is surprisingly slow and drawn-out. The whole universe is matter, as far as we can tell. No one is sure why there's more antimatter than matter, since the laws of physics are pretty symmetrical, and so there's no reason to expect there to be more of one than the other.[1]Although when it […]

The Golden Rule of Food Shopping: Never shop for groceries when you’re hungry. Corollary for Mattress Shopping: Never shop for a mattress when you’re tired. When buying a mattress, Consumer Reports recommends that you lie down on “lots of mattresses” in the store and spend at least 15 minutes on each mattress — five minutes lying on […]

A special issue of the Journal of Mathematics and the Arts entitled "Poetry and Mathematics" is now available online at this link.  An introduction by guest editor Sarah Glaz is available (for free download) here.   In this opening piece, one of the items that Glaz includes her own translation of a math-puzzle poem from Bhaskara's (1114-1185) Lilavati that is charming.  I offer it here:        Ten times the square root of a […]

Visit Every State How fast could you visit all 50 states? —as discussed by Stephen Von Worley on Data Pointed This week's article is a little different. Instead of answering one of your questions, I'm going to look at someone else's answer to a question, and how thinking about that answer raised some new questions of my own. Eventually, the whole thing sucked me down a rabbit hole of calculations from which I barely escaped. In the summer of 2012, the blog Twelve Mile Circle […]

Every poem has a climate -- a collection of emotional tones that overlay and underlay its words. Today -- as the U.N. meets in NY to discuss the future climate of our planet -- I have been looking for mathy poems with a climate of advocacy, verses that let the world know that we must, soon and vigorously, take action to keep our earth habitable.      One of the things I found is a poem (involving a couple of numbers and mathy words) by Simon […]

Old farts will know the answer to this old trivia question: What two letters do not appear on a phone? And if your phone still looked like this… then it would be a reasonable question. But phones don’t look like that anymore. They look like this… in which case, it’s a really dumb question. (The Q […]

Today I want to call attention to the growing global concern about climate change accentuated by the United Nations Climate Summit that opens September 23. Tomorrow (September 21) I will travel on a 6 AM bus  from Silver Spring to NYC to be part of the People's Climate March.  It is said that more than 500 buses of protesters are heading to New York. 29 marching bands will provide the soundtrack. 26 city blocks are being cordoned off for the march's […]

A ditloid is a puzzle in which a fact must be discerned from the numbers and abbreviated letters in the clue. For example, 7 D in a W is a ditloid for “7 Days in a Week,” and 20 V on a D is a ditloid for “20 Vertices on a Dodecahedron.” Here’s a ditloid in honor of International Talk Like […]

Balloon Car My 12-year-old daughter is proposing an interesting project. She is planning to attach a number of helium balloons to a chair, which in turn would be tethered by means of a rope to a Ferrari. Her 13-year-old friend would then drive the Ferrari around, while she sits in the chair enjoying uninterrupted views of the countryside. Leaving aside the legal and insurance difficulties, my daughter is keen to know the maximum speed that she could expect to attain, and how many helium […]

Lee Lorch was a mathematician known for his social activism on behalf of black Americans as well as for his mathematics. He died in February of this year in Toronto, at age 98.  A life-long communist and a life-long crusader.  Last Thursday I attended a memorial service  (organized by Joe Auslander, a poetry-lover who one day had introduced me to the work of Frank Dux) for Lorch -- sponsored by the Mathematical Association for America and held at the MAA […]

Before reading 365 Things That Make You Go Hmmm…, I hadn’t realized that I’d been on Earth for 1.3 billion seconds, and I never thought about what someone would feel like after spending a day in my mind. That’s the beauty of this incredible book — it asks you to think about things that you’ve probably […]

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 […]

To show my sons what Siri can do, I asked her (it?) the following question: What is 6 + 4? Siri told me, “The answer is 10.” But she also provided a bunch of other information pulled from Wolfram Alpha, including the following data: This data appears to be taken from dissertation research by B. A. Fierman which […]

All of the following jokes were borrowed from Reader’s Digest, which I’m sure they borrowed from elsewhere. Did you hear about the mathematician who’s afraid of negative numbers? He’ll stop at nothing to avoid them. How easy is it to count in binary? It’s as easy as 01 10 11. A Roman walks into the […]

We computer-screen readers all know hypertext; when we read along in Wikipedia or some other online document and come across an underlined term whose font color is light blue -- at such a point we may decide to keep on reading as if we had not noticed the light blue "hyperlink," or we may locate our cursor on that text, click our mouse, and link to a new screen of visual information.     My first encounter with hypertext poetry was the work of Stephanie […]

When my college roommate contracted crabs, he went to CVS to buy some lice cream. As you can imagine, he didn’t want to announce to the world what he was buying or why, so he put the box on the counter with a notepad, a bottle of aspirin, a pack of cigarettes, a bag of […]

Publishing a blog about poetry and mathematics brings me new connections -- it is not unusual for a day to begin with an email from another poetry-math enthusiast who wants to share a link or a poem. One of these is retired USC biochemist Paul Geiger.        Using as raw material a poem by Shel Silverstein, Geiger created a 9x9 syllable-square:S.C.S. STOUT     by Paul Geiger       Apologizing and Acknowledging Shel […]

Do you know what the following graph represents? Sine on the dotted line. If you tell that joke to the right audience, you’ll likely hear a triggle. (If you tell it to the wrong audience, you’ll likely hear the sound of tomatoes whizzing past your head.) Triggle is a portmanteau, a combination of two or […]

All the Money People sometimes say "If I had all the money in the world ..." in order to discuss what they would do if they had no financial constraints. I'm curious, though, what would happen if one person had all of the world's money? Daniel Pino So you've somehow found a way to gather all the world's money. We won't worry about how you did it—let's just assume you invented some kind of money-summoning magic spell. Physical currency—coins and […]

This year's math-arts conference, Bridges 2014, was in Korea.  And a dozen of us who write poetry-with-mathematics -- unable to attend in person -- worked with coordinators Sarah Glaz and Mike Naylor to offer (on August 16) a virtual reading of work videotaped in advance by the poets.      The virtual reading is here on YouTube.       Mathematician-poet participants (links are to poems posted in this blog)  include […]

It was my good fortune last weekend to meet the sister-in-law of one of my neighbors, mathematician and Harvey Mudd professor, Rachel Levy.  Levy is also a blogger and her postings in Grandma Got STEM tell of achievements of women in science.     I have looked for a poem to pair with my mention here of  Grandma Got STEM.  Although the following poem by Tami Haaland (found at the Poetry Foundation website) is not mathematical, it […]

Walking New York Could a person walk the entire city of NY in their lifetime? (including inside apartments) Asaf Shamir Like the answer to Paint the Earth, the answer to the first part of this question is pretty straightforward to look up. But what if it weren't? Can we figure out the answer from things we already know? Let's look at a few ways of estimating it. First of all, how wide is a street? I've never seen one of those flashing crosswalk countdowns signs start with less […]

Into the Blue If I shot an infinitely strong laser beam into the sky at a random point, how much damage would it do? Garrett D. A lot of the time, if a question includes the word "infinity," the answer is "an infinite amount"—when there's an answer at all. An infinitely strong laser pointer would deliver an infinite amount of energy to the air in its path, which would in turn radiate an infinite amount of energy in all directions, which would destroy everything.

Saying that I like KenKen® would be like saying that Sigmund Freud liked cocaine.

I love to create math games almost as much as I love to play them. My favorite professional project was leading the development of Calculation Nation. And my favorite game on the site is neXtu, though other games on the site may promote more sophisticated mathematical thinking. I have many reasons to love my wife, […]
