ABSTRACT
I thank you for the opportunity to speak to the International Union of Pure and Applied Physics and the Corporate Associates of the American Institute of Physics. It is particularly appropriate that I voice my gratitude and appreciation for the invitation because I, in many ways, am an outsider to this audience of physicists. For example, I am in no way now a practising physicist. By this, I mean one who studies, teaches, and carries out research on the behavior of matter or one who applies to advanced technical projects the new insights gleaned from such research; and more than 20 years have passed since I was a serious student of physics. Clearly, I am not a practising physicist.
