Sometimes I do things other than math. Here are some photos.
I like rivers. This is me on the South Fork of the American River.
Here I am in some inflatable doo-hicky on the Tuolomne River.
I also like rocks. One of my favorite collections of them is the Buttermilks near Bishop, California.
This one is in Fontainebleau, France.
When I lived in Berkeley, I had a garden. Here it is in the late winter of 2010.
These are my tomatoes in the summer of 2010.
