``That may be true,'' he acknowledged, ``but it's completely accurate, and as
long as the answer is right, who cares if the question is wrong? If you want
sense, you'll have to make it yourself.''

My favorite mathematical expression.

My favorite mathematical picture: the
level curves of the 3D surface of

z = sin(x + y) sin(x - y) / tan^{-1}(x^{2} - y)
= (cos y^{2} - cos x^{2}) /
tan^{-1}(x^{2} - y),

which I denote "the lobo function" as it resembles the
University of New Mexico mascot.

Some photographs that I have taken.

A photo of me in Four Windows Lava
Tube, El Malpais, New Mexico

(taken by
Kenneth Ingham)--the silvery flecks
are the microbe actinomycetes.

A photo of me "jawboning" in Raleigh, North
Carolina (taken by Eugenio Roanes-Lozano).

What is a Ph.D. worth? The answer I learned
in St. Kitts!

The meaning of life, the universe and
everything.

My vita (for those that care about that kind of
thing).
