I started programming computers as a hobby in 1966, and have continued the practice, on again and off again, for the past 50 years.  My interest has always been in using computers to improve my understanding of complex physical systems.  In recent decades there has been substantial growth of interest in dynamic physical systems, especially of the adaptive kind.  My programming hobby has followed along.  Now, in retirement, I have opportunity to dig a little deeper into many things that I had to pass over, or examine only quickly,  during my working life.
