And such an anthology, which brings together such names as Hooton, Zinsser, Stanley, Galdston, Jaffe, DeKruif, Haldane, Hogben, Russell, Einstein, Kaempffert, Sears, Huxley, Millikan and as many more, up to the number of 33. The basis of selection is contemporary science, advancing frontiers of learning and knowledge of the nature of things, limited to a period of ten years, and written so that the layman can ""read, mark, learn and inwardly digest"". The first group deals with the biological sciences with the main emphasis on Life; the second part with the physical sciences with the emphasis on Energy. There is no attempt to present an orderly build-up of subject; there are necessarily divergent opinions. Stimulating survey for the man in the street which may take some near-scientists to primary sources. That it has the mark of scientific approval is evidenced by its choice by the Scientific Book Club.
