This book describes a number of simple methods for showing that light is polarised and determining the direction of vibration. It is based on a demonstration lecture, called 'Polar Explorations in Light' developed for young audiences, at the Royal Institution of Great Britain. "This is a fascinating book giving a wealth of details and examples of polarization ? There are wonderful color photographs ? Teachers will find this an interesting source of valuable information, well beyond what is found in most textbooks. Good students will find it fascinating reading but going well beyond what they will require for examinations."-Geoff Auty, School Science Review "David Pye's slim volume belongs to that rarest category of books that facture an inviting description of physical phenomena, simple demonstrations, lucid explanations, and a coherent story line ? Pye's deft descriptions and the photogenic opulence of optical phenomena ensure that physics is never short-changed in this volume ? a profusion of illustrations in straightforward language ? all optics researchers should buy this book ? ideal gift to steer undergraduate and graduate students toward the study of optics."-Akhlesh Lakhtakia, Optics & Photonics News
