Amateur theoretical physicist and coder by necessity. (I learned a HOL called MAD at the University of Michigan in about 1968, and not finding a job in physics in 1972 I managed to land a job as a coder. My penultimate coding achievement was coding a Kalman filter in my employer`s unique proprietary assembly language on a fixed point computer by developing a set subroutines emulating floating point options. After I did some programming of aircraft flight management in FORTRAN I graduated into systems analysis and management where I did no useful (programming) work for the next 30 years. As a retiree I am learning C on my own and returning to physics using it.
