Page 757 - If the signal frequency is very large compared with the electron gyrofrequency and the collision-frequency, one may write where e and m are the charge and mass respectively of the electron, and e0 is the permittivity of free space.
Page 765 - ... is the angle between the direction of motion of the particle and the direction of r.
Page 323 - N is the atomic density, e and m are the charge and mass of the electron, respectively, A is the mean free path and < v > is the average agitation velocity of the electrons.
Page 765 - C is the velocity of light, and 9 is the angle between the direction of motion of the particle and the observed beam.
Page 549 - If light is subject to gravity, if in any real sense light has weight, it is natural to trace the consequences of such a fact. One of these consequences would be that a sufficiently massive and concentrated body would be able to retain light and prevent its escaping.

Page 115 - Rejecting entirely the idea of magnetic or electric substance, the magneton may be regarded as an inner limiting surface of the aether, formed like an anchor ring. The tubes of electric induction which terminate on its surface give it an electric charge, the magnetic tubes linked through its aperture make it a permanent magnet.
