Query: Enjoyable overview for all interested in modern physics

This book is very readable and enjoyable to dip into.It is in no way a technical treatise, more a detailed glossary (topics are presented from A to Z ),yet a great deal of work has gone into making it such a comprehensive overview.It is a handy quick-reference guide to conceptually challenging subject matter.No knowledge of higher mathematics is required to understand most of the material in this book yet most topics and people concerned with the development of modern physics are covered.I particularly liked the appendix at the back which is in the form of a timeline of notable events,discoveries and dates of birth of contributing physicists.As a teacher of physics in the 16-19 age range I would recommend it (and have done so on several occasions)as a background reference to all students intending to study physics at degree level. The interested layperson will also find it stimulating and accessible.Well worth the money.Buy it.
