FQXi essay & dedication

Posted in Uncategorized on February 14, 2011 by quantummoxie

My father-in-law passed away quite unexpectedly just over a week ago.  He was like a second father to me. He was young (68) and in reasonably good health (he’d been given a clean bill-of-health from his cardiologist just recently).  When he passed away, I was about two-thirds of the way through an essay for the latest FQXi contest and so I dedicated it to him.  You can read and vote on the essay here. I’ll miss Larry very much.
