John Petrakis, Economics; Richard Shoemaker, Business Administration; Charles Sehgman, Accounting; Fred Smith, Business Seminars; Raymond Gold, Business Administration; Russell Yoas, Business Ad- ministration. Business Administration, the largest department of the curriculuiTi, has the Dean of Academic Affairs, as the chairman. In addition to the speciahzed part- time instructors, Mr. Charles Sehgman, member of the Board of Trustees, has joined the faculty. Be- cause of his experience and study of the political and fiscal matters in South America last summer, Mr. Seligman contributed many interesting and broadening aspects in his class lectures. Mr. Seligman gives new insight into South American problems. Future Business Men and dates attend S.A.M. dinner. 23

Chemistry Through The Microscope Morton Huber Though more commonly identified with the bi- ologist, the microscope is a versatile tool for the chemist as well. Crystal patterns whose delicate but complex design and color harmony put the abstract painter to shame are a miracle of an in- telligence beyond our own. Who can peer into this hidden world of beauty without feeling the chal- lenge of research and at the same time a reverence for the vast unknown realm that lies literally at our finger tips? Too often the visible every day world lulls us into the false belief that we are masters of all we survey. More than a century ago Pasteur used the mi- croscope to separate crystals of optically active com- pounds whose identical chemical properties would not permit separation by any other known means. The polarizing microscope serves the metallurgist daily by locating invisible strains and imperfections. and S cience It can detect the presence of foreign matter that might affect the tensile strength or maleability of the metal. Even transparent crystals of pure chem- ical compounds show color patterns that aid in the identification of the compound. The electron microscope provides us with in- formation about protein molecules tinier than the smallest microbe. In contrast to the conventional microscope, its optical system depends upon bend- ing a beam of electrons instead of the usual series of glass lenses. This modern miracle is helping to reveal the structure of chromosomes, nucleic acids, viruses, and may prove to be a most useful tool in the final understanding of the nature of cancer and the miracle of reproduction. Our own work with the microscope is limited at the moment to studying the growth patterns of crystals, and to classifying them into geometrical groups. This information gives the microscope con- siderable importance in the field of qualitative analysis. 25
