*Casablanca*. Except it’s not what Ilsa, played by Ingrid Bergman, actually said, which was “Play it once, Sam, for old times' sake . . . [NO RESPONSE] . . . Play it, Sam. Play 'As Time Goes By.'”

This month’s column is in response to
the emails I receive from time to time asking for a reference to
articles I have written for the MAA since I began on that
mathemaliterary journey back in 1991. (Yes, I just made that word up.
Google returns nothing. But it soon will.)

I first started writing monthly
articles for the MAA back in September 1991 when I took over as
editor of the Association’s monthly print magazine

*FOCUS*. When I stepped down as*FOCUS*editor in January 1996, the MAA launched its website, and along with it*Devlin’s Angle*.
During that time, in addition to moving
from print to online, the MAA website went through two overhauls,
leaving the archives spread over three volumes:

January 1996 – December 2003

January 2004 – July 2011

August 2011 – present

Throughout those 23 years, I’ve
wandered far and wide across the mathematical and mathematics
education landscape. But three ongoing themes emerged. None of them
was planned. In each case, I simply wrote something that generated
interest – and for one theme considerable controversy – and as a
result I kept coming back to it.

I continue to receive emails asking
about articles I wrote on the first two of those three themes, and
the third is still very active. So I am devoting this month’s
column to providing an index to those three themes.

I’ll start with the most
controversial: what is multiplication? This began innocently enough,
with a throw-away final remark to a piece I wrote back in 2007. I
little knew the firestorm I was about to unleash.

**Mathematical Thinking**

I first started making the distinction
between mathematics and mathematical thinking in the early 1990s,
when an extended foray into mathematical linguistics and then
sociolinguistics led to an interest in mathematical cognition that
continues to this day.

No introduction necessary. MOOCs are
constantly in the news. Though I was one of the early pioneers in
developing the Stanford MOOCs that generated all the media interest
in 2012, and I believe the first person to offer a mathematics MOOC
(Introduction to Mathematical Thinking), the idea goes back to a
course given at Athabasca University in Canada, back in 2008.
