Excerpt from A Manual of Physics: Being an Introduction to the Study of Physical Science, Designed for the Use of University Students The best advice which can be given to a student of physics regarding the books which he should read is to use separate works written on the various branches of the subject by the leading physicists of the day. Yet this advice has one evident disadvantage. The student who follows it may not get so complete a view of the essential unity and interdependence of the various branches of his subject as it is desirable that he should. And, besides this, there is no doubt that a small volume which gives, as far as is possible, a review of the elements of the whole subject, is a desideratum to the student while in attendance on University classes. I have undertaken the writing of this work in the hope that it may to some extent meet that want. I have throughout endeavoured to bring into prominence the necessity for, and the value of, scientific hypotheses - a matter regarding which very hazy notions are only too common. It has also been my aim to make the treatment of the mathematical portions of the text as simple as possible. In this connection I have not adopted the process which has recently been termed 'calculus-dodging, ' for the reason that the elementary methods of the calculus are more simple, certainly are more natural, than the methods by which they are usually supplanted. At the same time it may be well to remark that any student, who desires to do so, may simply assume the results of the mathematical portions, and use the remainder (which is much the larger part) of the text in his study of experimental physics. In writing a text-book on general physics it is impossible, if justice is to be done to the subject, to avoid borrowing methods from the writings of the masters.
