Excerpt from Practical Physics, Vol. 1: A Laboratory Manual Fro Colleges and Technical Schools

The authors believe that physical laboratory work should accompany lecture and recitation work in physics from the beginning of the study of this science in the college or technical school, and they believe that a laboratory manual should set forth a series of definite exercises. A general discussion of how to measure a thing is, in their opinion, not a satisfactory basis for the laboratory work of a student. This laboratory manual has been prepared with these ideas in mind.

A group of students who are beginning a laboratory course on the basis of this manual should be required to study the intro-ductory chapter, and to solve the problems illustrating the calculation of probable error.

The system which has been used with great satisfaction by the authors in the assignment of laboratory exercises is described on page 2. The authors believe that one of the most important aspects of laboratory work in physics is that it gives to the student a series of more or less distinctly theoretical problems based upon experimental data obtained by themselves, and in accordance with this idea, the authors believe that a student should be required to work up his laboratory reports outside of the laboratory as specified on page 3.

This manual is issued in three small volumes. The first volume is devoted to Precise Measurements and to Experiments in Mechanics and Heat, the second volume is devoted to Elementary and Advanced Measurements in Electricity and Magnetism, and the third volume is devoted to Photometry and to Experiments in Light and Sound.
