Excerpt from 1000 Exercises in Physics
The aim of these Exercises is to render assistance to the general teacher in preparing for his daily work; to the inexperienced teacher, by suggesting the turn which his instruction should take; to the pupil, by enabling him to make a careful self-examination of his attainments. He who interprets the last statement as being an encouragement to cramming, must, to be consistent, object to all questions, whether oral or written, whether by teachers or by authors. By placing copies in the hands of his pupils after the different branches of physics have been thoroughly discussed in the laboratory and classroom, noting such questions as he would have them ponder, and encouraging them to extend their information beyond the limits of their prescribed text-book, the author expects these Exercises to become a valuable auxiliary in his instruction.
Inquiries have been pushed into the field of speculative science, so that the pupil may catch a glimpse of the future physics as descried by Rowland, Thomson, Maxwell, and others; and a view of these things, hurried though it be, will, it is hoped, awaken in him a desire to peer more deeply into the mysteries of nature.
The author hopes that errors in the following pages will be treated with leniency; and, on the ground of being a much-employed teacher, begs to be excused from answering questions upon the subject matter, - the usual penalty for preparing a book.
