Research Films in Biology, Anthropology, Psychology, and Medicine

Man has distinguished himself from all other animal species by his ability to formulate coherent thoughts, to express them in a number of languages, and to record them permanently through such media as canvas, paper, film, and magnetic tape. This excellent practice has led in the field of the experimental sciences to an ever-growing literature of journals, monographs, reviews, and books which has now reached the stage where, on an average during the last twenty years, two new scientific journals have started publication every day (1465). This extremely rapid growth of scientific knowledge has brought with it, in turn, a host of new ideas and new words. It has therefore become more important than ever to define precisely the frame of reference on which alone an exchange of ideas can be based. Such definitions are particularly needed in the field of cinematography.
