Excerpt from The Study of Electricity, by the Deductive Method
Many years ago the author discovered the fact that an endless flexible shaft revolving about its geometric axis was a helpful analogy of the transmission of energy by electricity. The applications of this analogy have been extended at intervals, and a pamphlet on the subject was published in 1915.
The analogy when used in connection with a single working hypothesis has universal application, affording the student the advantage of the deductive method of study. A considerable number of students have from time to time expressed their appreciation of the assistance they have derived from the use of this analogy.
Only quite recently has the attempt been made to extend the analogy and its accompanying working hypothesis to the solution of all the problems of electric transmission of energy by both direct and alternating current. The result has led to the publication of this book.
Caution - The student or the critical reader should keep clearly in mind that the analogy used as a basis for deductive study is not here presented as a theory. Neither the value nor the results of the method are at all dependent upon our views as to the probability of the real existence of the elementary flexible shafts referred to in the analogy.
