It is proposed that the electron should be considered classically as a charged conducting surface, with a surface tension to prevent it from flying apart under the repulsive forces of the charge. Such an electron has a state of stable equilibrium with spherical symmetry, and if disturbed its shape and size oscillate. The equations of motion are deduced from an action principle and a Hamiltonian form alism is obtained. The energy of the first excited state with spherical symmetry is worked out… Expand
The Nature of the electron
Through investigating history, evolution of the concept, and development in the theories of electrons, I am convinced that what was missing in our understanding of the electron is a structure, intoExpand
Models of the Classical Electron after a Century
The point charge and the extended charge as models of the classical electron are studied. The problems inherent to each model with respect to self-interaction are disclosed and the possible solutionsExpand
Classical Electron Models
An electron, in an Abraham-Lorentz-Poincare model, is a uniformly charged spherical shell (Abraham, 1903, 1904; Lorentz, 1952; Poincare, 1905, 1906). A non-electromagnetic (“mechanical”) attractiveExpand

The Dirac equation, which was derived by combining, in a consistent manner, the relativistic invariance condition with the quantum probability principle, has shown its fecundity by explaining theExpand
Classical time-symmetric electrodynamics
A brief review of the classical aspects of the absorber theory of radiation is presented. The divergences which arise from the use of time-symmetric electrodynamics are pointed out. It is shown thatExpand

Supermembranes, Superstrings, and Supergravity
A fundamental problem in particle physics concerns the structure of elementary particles: whether they are pointlike or extended objects. Lorentz [1] already considered relativistic models for anExpand
