From September through November, 2018,
a math-themed performance called
The Seven Bridges of Königsberg
popped up on the Georgia Tech campus and
around Atlanta, commemorating the birth of graph theory
in an article of Euler in 1736, with original music and dance.
Here
and
here
are some promotional
materials. Updated links will be posted when available.

* The Skiles building

pictures)
shows as a rectangle with a hole in it
and bears the number 2. To see it in relation to the whole campus,
go to
"Map Home".
My office location is in the southwest corner of the building.
The opinions on this and any of my pages at locations in

are my own, or else satirical, or honest errors. They are not
necessarily those of
Georgia Tech,
although most of them should be.
