The Particle Enigma

Wheeler’s “charge without charge” concept where 3-dimensional space is represented as a 2-dimensional hypersurface with a wormhole. The dimension off the surface has no physical meaning. The lines threading the wormhole are the electric field lines. [Adapted from J.A. Wheeler, Phys. Rev. 97, 511 (1955)]

The idea that particles are the basic constituents of all matter dates back to ancient times and formed the basis of physical thought well into modern times. The debate about whether light was a wave or a stream of particles also lasted until relatively recently. It was the advent of de Broglie’s work and its implications that revolutionized the concept of an elementary particle — but unfortunately did not banish the idea of a point particle despite its difficulties in both classical and quantum physics. Some of these problems are discussed in this essay, which covers chiral oscillations, Penrose’s “zigzag” picture of particles satisfying the Dirac equation, and some ideas derived from string theory.
