This book is an attempt to share some of the fascinating and exciting ideas of modern theoretical physics with a non-mathematical audience. I also hope to give some appreciation of the exceptionally creative people who have generated these ideas. I had no intention of writing a comprehen- sive history of these ideas, however; I apologize to those physicists whose important contributions I may have omitted. Several people have contributed directly to the writing of this book, and I would like to take this chance to thank them. Clive Horwood of Praxis Publishing and Paul Farrell of Copernicus...

A unified treatment of the various techniques used for distance determination. The text begins by describing methods to measure distances on Earth, then gradually climbs the "distance ladder" to enable us to estimate the distance to the farthest objects, ending with a discussion of particle horizons within an expanding and inflationary universe. Aimed at first-year astronomy and astrophysics undergraduates, the book emphasises general physical principles rather than mathematical detail, and is enhanced and complemented by many worked examples, questions and problem-solving exercises at the...

Using data collected from all parts of the continent, this book is a study of the health of Australia's original inhabitants over 50,000 years. It represents the first continental survey of its kind and is the first to quantify and describe important aspects of Australian hunter-gatherer health. Major categories of disease described are: stress, osteoarthritis, fractures, congenital deformations, neoplasms and non-specific and treponemal infections. The author also describes some surgical techniques used by Aboriginal people. A broad-ranging book offering fresh insight into the study of...
