Reseña del editor

It is of fundamental importance to be able to predetermine with .as much numerical accuracy as possible, the phenomena which may take place in electrical systems. It is of importance first, because such predetermination, when possible, can be made at much less expense and trouble than is required to obtain the same information experimentally; and second, because information so obtained opens a way to new developments and improvements in the application of scientific knowledge. To predetermine in a numerical way what may happen in electrical systems imder different conditions requires that the various phenomena be expressed in a mathematical form or the equivalent thereof. Of cotirse it is not the mathematical expressions themselves which are of main interest, but these expressions are necessary since they afford the only means at our disposal, other than experimental investigation, by which the desired knowledge may be obtained. In this volume an attempt has been made to set forth the mathematical developnents leading to solutions for a number of problems arising in connection with the transmission of electrical ;energy over metallic circuits. The fundamental equations for the propagation of currents and voltages along an electrical circuit consisting of parallel conductors or the equivalent thereof have been developed and presented by a number of writers Heaviside, iF leming, Pupin, Steinmetz, Kennelly and others; but it has been Kthe writers experience to note that the application of these developments to present-day engineering problems has been comparatively rare. This has been due partly to the unfamiliarity of a great many of engineers with the particular type of mathematics necessarily involved in such discussions, and partly to the fact that the presentation of the material in various publications has not been in such a form as particularly to invite
