Belgian Puzzle Art
From the Belgian artist of the March 25 New Yorker cover —
“There comes a time when the learner has identified
the abstract content of a number of different games
and is practically crying out for some sort of picture
by means of which to represent that which has been
gleaned as the common core of the various activities.”

the abstract content of a number of different games

Sunday School
The late mathematics educator Zoltan Dienes in 2002 published
an article containing the following cryptic confession —
"Nowhere will I give away how I stole these patterns
from the mathematician's secret closet."
Some of the patterns he may have been referring to were
hardly secret. See a website recorded in the Internet Archive
on the Feast of St. Nicholas, 2000.

Dienes reportedly died at 97 on Jan. 11, 2014.
From this journal on that date —
A star figure and the Galois quaternion.
The square root of the former is the latter.
