In January 2008, I spent a week in
Athens, Greece, as a guest of
the Hellenic Physics Society
participate in the Second
International Science and Art Conference
. I am very grateful to
the Society, to Prof. Nikolaos G. Nicolis, and to Dr. Dimitra
Lelingou, coordinator of the organizing committee, for inviting me to
and for making many excellent
arrangements. This web page shows one of the workshop activities I led
during the visit.
Start with five copies of the template
heavy colored paper.
Cut out the squares. (And special
thanks to Susan Ligthart, right, who translated for me.)
There are six squares in each of five colors, thirty in total.
Each square has four slots, two long
and two short. Cut exactly to the end of each line.
Slide a long slot and a short slot
together. Make a cycle of five, with five different colors.
Then add a third square to each pair,
making small triangles.
The color pattern is important. Each square mates with four squares of
Squares with parallel edges are the same color.
Continue to build all around the sphere, being sure to make nice
The last piece is a bit tricky. It has to bend around four others.
The result is very pretty. You can see it as five cubes, one in each

templates and some related constructions, see this paper
Looking inside through the holes is nice too.
The conference was held at the "Gazi"
Technopolis, which is an old gas works that has been converted
beautifully into a conference center and industrial museum. Two gas
storage tanks have been replaced with circular buildings, while
retaining the old surrounding iron work. The above building contains
the main lecture hall, where I presented a paper surveying my sculpture
Of course I also visited wonderful historical sites, such as the
