Abstract
As a layman to the field of cosmogony, one of the greatest problems I face is that of trying to visualize each contrasting view of origins. This difficulty has at last been overcome in a filmstrip which contains lucid diagrams that are excellent from the standpoint of art, and in addition are based upon detailed research. Although it is thus squarely rooted in the data, this presentation is not "stuffy" and the documentation actually adds to the general appeal of this filmstrip.
