When we first approached some colleagues allover the world to sound them about a volume dedicated to Professor John Xanthakis on the occasion of completing twenty-five years of scientific activities as fellow of the National Academy of Athens, any possible doubts as to the feasibility of the project were quickly dispelled by their warm and encouraging response. In a short time 50 authors from 15 countries, coming from a wide range of Professor Xanthakis' immediate colleagues, pupils and friends joined to produce the 36 contributions included in this volume. Some of those who where originally approached found themselves un able to contribute, because of the time-limit necessarily imposed. Happi ly, they were only few in number, and we should like to record our grat itude to them for their good wishes for the success of the venture. Their warm words were among the many sources of inspiring encouragement extended to us.
