摘要:

The detailed quantitative theory of a two-carrier, constant potential, electrostatic generator is given. It is shown that if the inductor of such a machine is held at constant potential, the collector voltage also approaches a constant value, which is proportional to the potential of the inductor, the factor of proportionality depending only on the geometry of the machine. It is shown that a Van de Graaff machine can be considered as a generator of the same type except that the two separate carriers are replaced by a single continuous belt. Some erroneous conclusions commonly made with respect to the action of the Van de Graaff machine are discussed. It is pointed out that a possible advance in the application of belt-type generators is operation in series to attain higher voltages.

摘要:

The equations for the speed of waves in the following cases are derived in an elementary way: transverse waves along a stretched wire and through an elastic solid; longitudinal waves through a fluid in a uniform tube, through a uniform rod, and along a stretched spring; long gravity waves through a shallow canal. Several errors in previously published derivations are pointed out.

摘要:

The work of Dirac, Bopp, Hönl, and Wessel on the theory of the electron is briefly reviewed. The equations of motion, with a variable rest mass, are integrated to obtain the velocities. The initial condition in this development can be so chosen that one obtains a motion which is analogous to the “zitterbewegung” first derived by Schrödinger. The connection between spin and radiation reaction force is clarified.
