- Math 323-09 (Spring 2016): Calculus III
- Class home page.
- Math 510 (Spring 2016): Introduction to Graph Theory: Graphs and Geometry
- Course home page. (To appear soon.)
- The course includes an introduction to graph theory and hyperplane arrangements. It is helpful but not essential to have seen graph theory. It is important to be comfortable
with rigor, proofs, and abstraction.

Quotations of the Month
Proclaim Liberty throughout all the Land
The Liberty Bell
unto all the Inhabitants Thereof
(from Leviticus 25:10)
They that can give up
Benjamin Franklin, 1755
to obtain a little temporary safety
deserve neither liberty nor safety.
'Tis better to have loved and flossed
Than never to have flossed at all.
