Ahrens, Walter R.; Harley, Theodore L.; Burns, Elmer E. – P. Blakiston's Son & Co., 1917
While the new movement in the teaching of physics--the study of the physics of daily life--is the keynote of the recent text-books, yet the laboratory manuals still adhere to the old method, leaving the presentation of material from everyday life to the text-book alone. It is the authors' belief that the manual as well as the text-book should be…
