To arrive at results consistent with the relevant experiments, radiation of a given frequency f had to be treated as though it consisted of energy atoms (photons) of the individual energy hf, where h is Planck's universal constant. It is wonderful to share it with many of my SNO colleagues and their partners here in Stockholm and with hundreds more who contributed so much to our success, at Queen’s and our other Canadian and international institutions.” Professor Emeritus George Ewan speaks at the Physics Nobel Prize Dinner held in honour of Dr.
