Synopsis
Excerpt from Practical Physics
The World War has had many notable results, not the least important of which are: first, that it awakened a popular interest in and appreciation of physical and chemical science hitherto unmatched in the world's history; and second, that it led to an unparalleled concentration of able minds on practical or applied as distinguished from pure or theoretical physics and chemistry. There resulted many new applications of the fundamental principles of these sciences. Of these we have attempted to describe only such as seemed to us important in peace as well as in war; but even the few selected form an important addition to the domain of practical physics. We have doubtless included in this book more material than it is advisable for any class to undertake in a single year. This gives the teacher an opportunity to adapt his instruction to local needs and to the time available. We believe that it is most important to select Carefully just what material can best be used and to teach that thoroughly, rather than to try to touch upon many topics superficially. The present edition is as nearly like our former book in spirit, pedagogical method, and general content as the passage of nine years permits. In particular, we have tried to arrange the material in the most teachable order, to give clear and con cise summaries at the ends of the chapters, to set practical rather than artificial problems, to minimize the arithmetical drudgery involved in solving them, and to suggest many ques tions designed to get students into the habit of seeking useful information from the mechanics, artisans, engineers, and others whom they meet outside the classroom.
Présentation de l'éditeur
This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.
