Excerpt from Discussion of the Precision of Measurements: With Examples Taken Mainly From Physics and Electrical Engineering The material presented in this volume is the outcome of several years' teaching of the subject. In a less complete form it was prepared for lecture notes and was printed in pamphlet form, but not published, by the Massachusetts Institute of Technology in 1888, having appeared in the Technology Quarterly and in the Electrical Engineer in 1887. In this revised form, the author has felt that it perhaps possessed sufficient completeness and originality to be of interest or value to students and teachers, and therefore to merit publication. In venturing to urge the importance of the subject as a course of study for engineers and for students of physics or other pure sciences, the author would suggest the value of the attitude of mind produced by it. One who has in any reasonable degree mastered its methods, although he may never apply them directly, will not only have increased his power to intelligently scrutinize experimental results, but will have acquired a tendency to do so. And it is perhaps not too much to hope that he may acquire a notion of a judicious distribution of effort which, with the best of results to himself, he may carry into quite other matters.
