"In tonight's Science Review R M Sillitto discusses the latest attempt to construct an organ which will play harmoniously in any key. This is the McClure Organ at present [1952] in the University of Edinburgh."

"Of all the bodies concerned - the Sun, the Earth and the other planets, and the moons of the planets - the body most accessible to us is the Earth. So - could one weigh the Earth? "

". . . it isn't anything in the nature of science that may make its practitioners Philistines - it's the specialisation of modern education that may make Philistines of people who pursue advanced studies in any field"

"In the 18th century, as the result of a marriage between a Clerk and a memberof the much grander Maxwell family, an estate at Middlebie in the south-westof Scotland came into the possession of the Clerks, but with a condition thatthe holder of the estate must not hold a Clerk property, and must be calledMaxwell."

"These waves are not approximations to some subtler truth : they are precise, valid solutions of correctly formulated problems in quantum optics."

"In fact, I think that if we abolished the word 'photon'from our vocabulary for ten years, we should find thatwe could get on perfectly well without it"

"So we believe we now understand why the Maxwell theory was so successful in supporting the design and analysis of all opticalexperiments and all optical instruments known before 1960; and why the Maxwell theory will continue to beuseful in much of optical and most of radio science in the future. But in additionwe have glimpses of a wider range of phenomena, still largely unexplored andunexploited – and still relying on the Maxwell theory for the classical foundationon which quantum optics has to be built."

" . . . but I’ve been delighted and excited tosee how much insight into optical systems and diffraction comes from a systematicuse of symmetry ideas - even for someone like myself who hasn’t yetachieved any grasp of group theory!"

"This is a spectacular finale to a remarkable book. . . . This, of course, is not the end of the story. Some day, someone will be writing about the fusion of quantum mechanics and general relativity into a true 'theory of everything'. But that is for another generation!"

"Principles of Optics is, and will remain for many years, an indispensable and vital component in any optical library . . . It is a splendid book."
