In this book, the interesting results of similar works carried out by both authors independently, is presented in a unique manner. This book is written as a token of exchange between the East and the West and it is hoped that it will lead to greater cooperation between the scientists.

This unique volume is a collection of papers on various problems in astrophysics and cosmology — from planetary motion to the arrow of time — that are closely linked by the common spirit, technique and methodology of chaos.

This volume is dedicated to Riccardo Giacconi for his sixty-fifth birthday, on the occasion of his being awarded a “Laurea Honoris Causa” in physics at the University of Rome “La Sapienza”. A meeting was held in his honor, and presentations were given that reflected the state-of-the-art of research on subjects related to Giacconi's scientific interests and achievements through the decades. This volume is based upon the papers presented at that meeting. It provides a tribute to Riccardo Giacconi for his outstanding contributions towards opening up the entire field of high energy astrophysics.
