Excerpt from Laboratory Exercises in Elementary Physics: A Manual for Students in Academies and High Schools
This little work is, as its name implies, simply a manual of exercises in elementary physics. No claim is made that it embraces all the exercises suitable for work of this grade. It is believed, however, that the exercises as herein presented constitute a sound basis for a strong, rational, and flexible course in elementary laboratory physics.
There has been no attempt in this book to usurp the functions of the teacher. Much of the details of the work are most effective when they come directly from him. The inspiration must also come, in large measure, from the instructor; no book can take his place in this particular.
In handling laboratory work in physics of any grade, the instructor is confronted at all times with the serious problem of providing apparatus. This problem is all the more serious in view of the fact that good work, even in elementary physics, is quite impossible without reasonably good apparatus. Speaking to this very point, Professor Nichols has said: "The list of instruments essential to the carrying on of an effective course in laboratory physics is not a large one. It includes certain standard apparatus, such as the balance, the air-pump, the thermometer, the projecting lantern, the electrical machine, and the galvanometer; together with such accessories as are necessary to use with these instruments. Without such an equipment, no college or school should attempt to give instruction in physics."
