ROBINSON, Pres., Summer Session Engineers. arrived from Harvard, is conducting a graduate course in spectroscopy. This sience dealing with the spec- trum of atoms which send out light vibrations, In spectroscopy an attempt is made to gain information about the atoms which are the source of the vibra- tions by measuring the vibrations themselves.. Professor Saunders gives this simile: "It is as though we went to a concert with our eyes closed, and listened carefully and even made measurements to find sound vibra- tions that were coming to us, and then tried to reason out without op- Exchange Notes :New York U'niversity-Students of the merchandising apd retailing ening our eyes, what kind of instru- ments those came from. We would find in that case mathematical laws connecting the vibrations from which we could infer the general form of the sources of these vibrations, or of these musical instruments. "And so much vibrations emmitted by atoms relationships have beenl found which have given a better idea of the construction of these atoms than has been obtained from any oth- er single mode of approach to this. difficult subject. The course in spec- troscopy deals with experimental re- sults of such studies." Summer School Law- books. New and second-hand 'at Water's.-.Adv.
