Excerpt from The Atom
While the present volume is in the main devoted to an exposition of a new theory of the atom, the results which are incident to this theory have assumed an unexpected importance. New theoretical values for Rydberg's constant and Planck's constant have been obtained, from which numerical values of all of the important constants connected with the electrons have been derived, namely Planck's constant, the electronic charge, the masses of the electron and hydrogen nucleus. These agree within the limits of error with the direct experimental determination of these constants.
These new theoretical expressions have supplied the missing equation by means of which the dimensions of the two aetherial constants, specific inductive capacity and magnetic permeability, income separately known, a matter the importance of which has recently been emphasized by Sir Oliver Lodge. Not only have the dimensions of the two aetherial constants been found in terms of length and of time, but those of ordinary mass as well, so that the dimensions of all kinds of quantities, - electrical, magnetic and mechanical, - are capable of expression in terms of length and of time alone. A table of dimensions has been prepared giving the dimensions of the more common units in terms of length and of time, referred to as the space-time system of units.
