The motional mass of the electron : A reconsideration of present views supporting the lorentz and einstein equations

A new approach is offered to aid in the understanding of the physical phenomenon of the interaction of a moving electron and a deflecting electric field. Issue is taken with classical theory and proof is advanced to show that the mass of an electron is constant and independent of velocity but the inertia and elasticity of the electric field cannot be neglected. This material is scheduled for presentation as a conference paper for discussion at the AIEE winter meeting, New York, N. Y., January 27–31, 1947. ELECTRICAL ENGINEERING presents this material to stimulate debate on an important and controversial topic. Comments are invited.
