As it was said by one of the participants to this workshop"e; In our attempts to understand the spectral evolution of galaxies, we are fortunate indeed to have the ability to look back in time and observe galaxies as they were billions of years ago.

The idea to hold a conference on the Evolution of Close-Binary X-ray sources grew in the summer of 1984.

Plant hormone research is the favorite topic of physiologists.

This is a textbook on classical mechanics at the intermediate level, but its main purpose is to serve as an introduction to a new mathematical language for physics called geometric algebra.

This book sets forth and builds upon the fundamentals of the dynamics of natural systems in formulating the problem presented by Jacobi in his famous lecture series "e;Vorlesungen tiber Dynamik"e; (Jacobi, 1884).

Over the last decade we have witnessed a rapid change in our understanding of the late stages of stellar evolution.

Recent advances in observational and theoretical efforts in understanding the nature of cataclysmic variables had reached such maturity that there existed a strong, shared feeling among the workers in this field that an international colloquium sponsored by the International Astronomical Union would be timely.

Interest in statistical methodology is increasing so rapidly in the astronomical community that accessible introductory material in this area is long overdue.
