National Publicity Studios photograph WHITE, you might think, is white (the opposite of black), and that's all there is to be said about it, but P. Carlyon Coates and his photo-electric reflectometer, above, know better. As Mr. Coates will explain in a "Science Commentary" talk from YA and YZ stations at 9.15 p.m. on Tuesday, March 24, the photoelectric reflectometer measures whiteness—whether, for instance, a sheet has retained its original colour after, say, half a dozen washings of a given kind. This is part of the job done for the launderers, dry-cleaners and dyers of New Zealand by their Research Institute, which has its laboratory at the Wellington Hospital. Apart from commercial launderers and cleaners, most hospital boards are members of the Institute. In his "Science Commentary" talk, Mr. Coates, who directs the Institute's work, will talk about its research and the service it gives to members in other ways, and he will mention some of the surprising indirect results of its investigations
