Excerpt from The Elements of Electricity and Magnetism: A Text-Book for Colleges, and Technical Schools
The elementary theory of electricity and magnetism is essentially an extension of the science of mechanics,* and the purpose of this book is to develop the science of electricity and magnetism from this point of view.
The study of elementary physics, in one of its important phases is imaginative like the study of geometry, its purpose is to rationalize our experience of physical conditions and things, and the building up of the rational structure of physics should be the chief function of a text-book for students. This text has been prepared in accordance with this idea.
The attempt has been made throughout to bring simple practical applications into the mind of the student. It would perhaps be ridiculous in a descriptive treatise on physics for college men to consider in detail those things which are universally and perfectly known, but it is precisely such things that should be referred to in a rational treatise. If one is to rationalize, one must rationalize about something. It is a mistake, however, to shape science instruction prematurely to practical (economic) ends, but such "practical" instruction is a very different thing from the rational study of the things of everyday life. Elementary science instruction must be made to touch upon the things of everyday life if it is to be effective. In no other way can what is best in science be realized anew in each succeeding generation of men.
