It seems to me that my professional career has spanned a period of progressive and rapid changes, including as it does the start of the nuclear age, space travel and the second World War and a period, since that war, of development in technologies that has stemmed in large part from the need to defend ourselves. Underlying this need, it appears to me, has been a major increase in speed whether in communications or in weapons which, in turn, has made the reaction time to events as they occur even shorter.
