Physics

Abstract

THE high standard set in the author's “Heat, Light, and Sound” is fully maintained in the present work, which covers roughly the school certificate or matriculation range. For students following a school course it would be difficult to imagine a more efficient or attractive presentation of a subject which, thanks largely to the universal interest in wireless, may be regarded as the most popular branch of science, but is often handicapped by heavy or unimaginative treatment. The historical development is prominent throughout. This, as is nowadays generally realised, adds greatly to the reality and interest of science. Here, moreover, instead of the great pioneers being left as little more than names, they are made to ‘live’ by judicious sketches of their life and times, with portraits, numerous extracts from their original papers, and reproductions of their diagrams and apparatus. The lesser known experimenters receive due recognition, in which connexion Bennett's work and original illustrations are notable. Equally with the historical aspect a practical line of study is followed, aided by a wealth of simple diagrams and numerous ingenious and up-to-date modifications or improvements of the usual experiments. Practical applications to everyday life are emphasised.
