## My Baby Daughter

Here's a picture or two. Of course, she's 5 now, and I don't have any pictures of my son up yet...

## My Mathematical Interests

I am interested in fluid flow, dynamo theory (planetary and solar magnetic fields), evolutionary ecology, and finance. I guess that's mathematics. They all involve PDE's of some sort and diffusion.

## My Pedagogical Interests

I would like to introduce every mathematical idea with an appropriately chosen real world problem, and lecture for no more than 15 minutes at a time --- a mere 3 minutes longer than the typical attention span. (The additional time allows for jokes which don't require attention.)

I would also like to introduce beginning college students to a full range of useful mathematics, including "nontraditional" applications such as codes & security, data compression, error correction in addition to standard topics such as differential equations.

A brief article, "Another Way To Graph a Sequence," (College Mathematics Journal, Vol. 27, No. 3, May 1996, pp 208-9) describes a useful way to graph a sequence so that limits superior and inferior can be apprehended visually. A Mathematica notebook (or a new version ) provides a reasonable way to explore the idea: plot (1/n, a[n]) instead of the usual (n, a[n]).
