What's the news?

None, my lord, but that the world's grown honest.

Then is doomsday near; but your news is not true.

## 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]).
