Ultimate Frisbee
-
I play as much as I can, which usually ends up being twice a week, or
so. Here in Durham, NC, it's not so remarkable to play through the
winter. But even back in Minnesota, from whence I just came, we
still weren't bothered by such trifles as "cold" or "snow": it's
surprisingly unpainful to play outside in the middle of winter, even
when it's -20 Celsius (around 0 Fahrenheit). In 2006-2007, I was in
Ann Arbor, Michigan, where the frisbee players enjoy the cold
reasonably as much as Minnesotans.
  The sequence of two pictures above was captured by
Dan Stedman (great shots,
Skip!), a General Lee
teammate, at
Cooler
2006, in Delafield, Wisconsin. A couple of seconds after these
photos were taken, Tiffany
Davis (number 01, in orange -- duh!) was already in
the end zone, where she caught the continuation pass.
The defender is John Fieberg, also from the Twin Cities. More
Frisbee photos, mostly
General Lee in 2006 and 2007, but also one Huzzah team photo.
Music
-
Here is a scan and analysis of a fugue I
wrote, which (faded using the image viewing program ``xv'') doubles as
the background for the page you're reading. Yes, that is my
handwriting -- I work with a real calligraphy pen, dipped in ink. I
dream someday of having links here to more of my music, including some
Baroque style dances, inventions, preludes, etc. Maybe I'd scan in
the symphonic material, too. With some luck, I'd even be able to set
up a link to some sort of electronic performance of some of these
things.
My favorite composers are Bach, Dvorak, Schubert, and Handel. Mozart is
sometimes quite good, too, but usually I prefer it when he's being
serious (Mass in c, Requiem in d, later symphonies, some piano
concertos). Palestrina and Victoria wrote some supremely beautiful
counterpoint, but I unfortunately don't own much. I do also like various
kinds of rock and popular music, but my feeling is that I can listen to
that nearly anywhere, when someone else is playing it for themselves. So
I listen mostly to classical at home.
Biochemistry
-
I did laboratory research at the National Institutes of Health (NIH) in
Bethesda, Maryland for a few summers in a row in the early 90s, on
gene regulation and expression in mammalian cells and yeast, and on
protein interaction in yeast. I still try to keep informed on such
subjects. I enjoy discussing biochemistry, molecular biology,
genetics, and other kinds of biology with researchers, for their
perspectives and for potential projects relating to mathematics.
During the 2007-2008 academic year, I took part in the
IMA Thematic Year on
Mathematics of Molecular and Cellular Biology.
Physics
-
Toward the end of grad school, I developed a side interest in
theoretical physics. I never took physics beyond high school, but
knowing some requisite math makes certain kinds of physics rather
accessible, as these things go (e.g., quantum mechanics = quantum
field theory in zero plus one dimensions).
