Ss a ig Om ad fr The SCIENCE READER’S COMPANION The reader of Science Fiction will welcome this handy “companion” and the assistance that it will afford him in understanding some of the words and terms that are encountered in his reading. It will be of value also to the student in all branches of science, and to the layman whose interests are mainly in the reading of “popular science” books. THE SCIENCE READER’S COMPANION has been compiled by a group of experts into a comprehensive book of reference, giving simple explanations and clear definitions of modern scientific terms and technical words, enlarging on many of them by diagrams and illustrations.
