Scientific Computing Experience
I have substantial computer experience, including
extensive experience in the languages: C, Fortran, Pascal, ADA, SIMSCRIPT, 6502
machine language, Mathematica, Maple, MatLab and MathCad. I have also spent time working on the
following platforms and operating systems:
VMS, UNIX, DOS, Windows 3.1, Windows 95/98/NT, and Silicon Graphics
including the forms graphics library.
FAMILY, then flying small airplanes, science fairs, cycling including velodrome (including in the past track) racing, cross country skiing, rowing, sea kayaking, choir. In 1991, I was a collegiate national cycling champion.
When I first got to USNA
Here I am in 1973 at USNA. Above left is just after I joined the sailing team. Above right is me in front of Chauvenet Hall, right after I joined the faculty, not too long after I graduated from grad school, and just before my first Nobel prize.
Here I am in 1971. In this picture, I am conferring with current faculty member at USNA, and a former colleague of mine who gave me a horse ride long before we were on the same faculty together.
