Wave-particle duality is a term used to describe the modeling of nature by both wave theory and particle theory. In essence, physical phenomena (e.g. electrons, photons, etc.) can exhibit varying degrees (sometimes determined by the experiment...

The nature of light is a very old issue in the history of science, dating back at least to Greek times. The prevalent belief among eighteenth-century natural philosophers was that light was made up of particles, not waves. The revival of the wave...

At first, light was assumed to behave like a shower of particles. With further research, it was decided light actually behaved like waves. Then, in the twentieth century with even further research, it appeared again as if light behaved in many ways like...

Two-slit experiments performed earlier by Tsuchiya et al. and recently by Afshar et al. demonstrate the joint wave-particle properties of the single indiviual photon, and agree with Einstein's argument against Complementarity. These results cannot be explained by conventional theory in which Maxwell's equations...
