Hay
Kia
ora!
(Hello! in the language of
the New Zealand Maori people.)
My early years were spent
alternating between my birthplace New Zealand and
the U.S., with the intervals increasing
progressively. Two years in NZ, three years in the
US, four years in NZ
and then, destroying
the sequence, some twenty-plus years back in the
US.
After graduating from high
school in Iowa City, Iowa, I went to college for a
year and dropped out. Yes, I was a college dropout
! For a couple of years I worked a lot of
mostly-dull and unrewarding jobs. This life
eventually lost its appeal and I returned to give
the University of Iowa another try. After
completing an undergraduate degree with a major in
computer science, I set off to the sunny southwest
and the University of Arizona, where I completed
masters and doctoral degrees in computer science
with minors in mathematics. It was during these
years as a graduate student that I moved to Phoenix
and began teaching mathematics and computer
science, first at Phoenix College and, later, at
Mesa Community College.
Today, I teach software
design classes at Clemson University in South
Carolina. I also indulge my lifetime interest in
handcrafts -- making soap and ceramic and stained
glass pieces. I also keep fit and maintain mental
health by jogging regularly.
Many people who know me
through my crafts and physical activity are
surprised to learn of my love of mathematics and
mathematics teaching. For me, all my activities are
interrelated. I see and use mathematics everywhere.
For example, many of my ceramic and stained glass
designs are geometric and require careful analysis
of the angles, and strong 3-D visualization skills.
My most recent project is a great ditrigonal
icosidodecahedron. I am constructing it from twelve
hexagons and sixty triangles.
My jogging routine is
riddled with mathematics. I keep track of mileage
and increase my mileage by a sensible percentage
each week. I also need to make sure that my
distances have increased to 13.1 miles just before
I'm due to run a half-marathon. I am aware of my
heart rate and try to keep it within the lower end
of my training zone (65%-70% of
maximum).
I try to help students see
and enjoy the math that is all around them. I like
to show them how math allows you to make beautiful
things, to arrive at wondrous results, and to
record precisely the steps used for later
reference. To truly enjoy mathematics I believe
students need to do math, see math, and even feel
math.
