Sometimes I think we're alone in the universe, and
sometimes I think we're not.
In either case the idea is quite staggering.

Current Project:

I am currently at work on a web-based epidemiology course in conjunction with Drs. Mark Wilson (of Biology and Epidemiology, University of Michigan) and Geoff Jacquez (of Ann Arbor-based BioMedware, Inc.).


"I'm sorry to say that the subject that I disliked was mathematics. I have thought about it. I think the reason was that mathematics leaves no room for argument. If you made a mistake, that was all there was to it."
Malcolm X, from The Autobiography of Malcolm X,
51st on one list of greatest non-fiction of the 20th century.
I'm sorry that I didn't get a chance to talk to Malcolm X about mathematics!

Bertrand Russell had a more positive take on it.


Let's go to the movies!

My dad and I made some movies over the summer which I really like. Have a look at his home page for them (and some other images representing our cooperative research). Those movies are not as big and slow as the others which follow below (but they're still big and slow!). Here's my dad's latest creation (created using a new technique of ours), which he's carving in wood.

As a graduate student I made an mpeg movie using the UNIX shell script make_movie. It shows how the weights in an interpolation scheme change as a function of the smoothness of the data (for those "in the know", as the nugget varies).

Here's another one, showing how neighbor weight is a function of the position at which one is interpolating, for a spherical model. Here's the same thing, only for the gaussian model. They're very similar.

Finally, I have one showing Abe Lincoln being unceremoniously decomposed, then recomposed, via the Singular Value Decomposition.

Other things to do with html files:

  • Run telnet from within them: telnet sabio, the library server at the University of Arizona.
  • Help people pick up software: To get a copy of our UNIX version of the popular PC geostatistical software Geo-EAS, visit the Geo-EAS Home Page.

  • Presentations on-line:
