Author Description

Excerpt from Elementary Physics The purpose of this book is to make the pupil acquainted with the more elementary facts of physics and physical chemistry, to give some idea of methods of experimentation, to illustrate the drawing of conclusions from experiments and observations, and to show that theories are merely attempts to explain, by means of certain suppositions, various phenomena whose existence is unquestioned but whose nature can not be more satisfactorily explained by other means. In order to secure these results within the time usually devoted to physics in a high-school course, it is necessary to limit the number of phenomena selected for study. In this selection we have been influenced not only by the desire to choose those phenomena most worthy of study, but also by the necessity of confining the choice to those phenomena which admit of a logical treatment within the limits of this book. It is considered inexpedient to attempt to include all matters of popular interest. If the material here selected does not fully occupy all the time of the pupil, the teacher may with profit add a discussion of various other subjects of direct interest to his immediate community. The arrangement of this material in chapters is due to the following considerations. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
