(A) Symposium on Illumination Lighting Calculations Encyclopédie photométrique

Abstract

THE march of progress in illuminating engineering is aptly illustrated by the three books before us. (1) The first of these, “A Symposium on Illumination”, comprises a series of lectures by experts, delivered in London under the joint auspices of the National Illumination Committee and the Illuminating Engineering Society in 1933. The book covers a wide field. Mr. C. C. Paterson's initial address on “Light in the Service of Mankind” is followed by lectures on radiation, gas and electric lamps, photometry, daylight and various applications (public lighting, etc.). The book thus represents a survey of modern knowledge, in the main simple andconcise. As Lieut.-Col. Kenelm Edgcumbe suggests in his foreword, it should be of interest to the non-technical, or at least the semi-technical reader. Probably, however, the chief appeal of the book will be to students, giving them an insight into a subject on which everyone ought to know something.
