The Quantum Theory of Light

Abstract
R Loudon Oxford: University Press 1973 pp xii + 338 price £7.50 One merit of Professor Loudon's book, uncommon in its field even in the attempt, is that he has cast it successfully in the tradition of normal physics texts. He starts roughly where undergraduate quantum mechanics courses leave off; introduces his topics as recognizably physics problems; keeps the mathematics to a reasonable minimum; and finally leaves the reader well placed not only to penetrate further technicalities but also to appraise them in context, and all the better for having been approached as a sane physicist, instead of being supposed ignorant of Planck's constant at the start and poised for engineering applications at the end.
