Annotation:
This book includes formulae for which some knowledge from a college course, would help but is not essential to enjoy the book. It is for future students of science subjects and also for those simply interested in Astronomy and Astrophysics. It will help a reader to know that this book is specifically an introduction to this fascinating subject, with the intention of providing a very wide overview assisted by many illustrations, putting it ahead of similar books but without going too deeply into the details which The Specialist might expect. This keeps the book more readable to the popular science enthusiast who may go on to seek more advanced material.
I have to thank my friend Howard Murray, Stockport, England for his translation from my English writings. He enjoyed the work but of course kept the book British concerning the selection of some phrases. American readers surely will forgive this.
