Lots of "Ah-ha!" problems.

### Continuing tradition: mathematics REU

Since 2001, I have been a contributor each summer to
the **"Research Experience for Undergraduates"** program run
by the
University of Chicago Department of Mathematics
(until 2011 under
VIGRE grants
from the NSF), directed by
Peter May.
For many years I gave an 8-week series on various topics
in Discrete Mathematics, and every year I gave a 4-week
intensive introductory series in the **"Apprentice program"** covering
**Linear Algebra** and its applications to graph theory,
combinatorics, probability theory, and algorithms,
as well as elementary **Number Theory**.
Both types of courses have been
accompanied by a potpourri of **fun problems**.
Course content is documented in great detail
on the web pages below.
In addition to the Math REU series, in summer 2014 an REU was
offered by the
**
Chicago Center for the Theory of Computing
and allied areas** (also listed below).
